    Although trichomoniasis has received attention as a cause of death among mourning doves (Zenaidura macroura),  ittle work has been done on other diseases of this species. Kossack and Hanson2 reported the occurrence of pox lesions in mourning doves in Illinois. Rosen3 reported that "pigeon pox" had caused a severe mortality in a mourning dove flock near Yreka, Siskiyou County, California. A severe outbreak of pox that occurred in a captive flock of mourning doves at the Patuxent Research Refuge further emphasizes the need for more study of this disease as a cause of dove mortality. Twenty-two mourning doves were live trapped on the Agricultural Research Center, Beltsville, Maryland, in September, 1958. The doves were examined for presence of Trichomonas gallinae and, when found to be free of trichomonads, were made the nucleus of a captive dove colony. A mourning dove that had a small, pink nodule on the left eyelid was captured on the Agricultural Research Center on September 17, 1958. The nodule was excised and the cut surface was treated with tincture of merthiolate. The dove then was added to the dove colony.

  2. Transcontinental mourning dove recovery

    A Mourning Dove (Zenaida macroura) banded in New York has been reported shot in California. On 25 August 1969, near Palmyra (43°00' N, 77°10' W), New York Department of Environmental Conservation personnel placed U. S. Fish & Wildlife Service band 883-97279 on the leg of a hatching-year Mourning Dove of unknown sex. During the first weekend of the dove season in September 1970, Stan Solus (P.O. Box 594, Seiad Valley, California) recovered the band from a dove he shot in the Shasta Valley, Siskiyou County, California (41°30' N, 122°20' W). As Mr. Solus included the band with his reporting letter and, in response to my asking him for verification, reaffirmed his original information, the recovery has been accepted as authentic. I suggest this vagrancy may be explained by assuming that the inexperienced New York bird got emotionally involved with a western bird with which it shared winter quarters, perhaps in Mexico, and thus the following year ended up a flower child in California.

    Mourning dove (Zenaida macroura) call-count surveys in Mississippi, USA, suggest declining populations. We used available mourning dove call-count data to evaluate long-term mourning dove habitat relationships. Dove routes were located in the Mississippi Alluvial Valley, Deep Loess Province, Mid Coastal Plain, and Hilly Coastal Plain physiographic provinces of Mississippi. We also included routes in the Blackbelt Prairie region of Mississippi and Alabama, USA. We characterized landscape structure and composition within 1.64-km buffers around 10 selected mourning dove call-count routes during 3 time periods. Habitat classes included agriculture, forest, urban, regeneration stands, wetland, and woodlot. We used Akaike's Information Criterion to select the best candidate model. We selected a model containing percent agriculture and edge density that contained approximately 40% of the total variability in the data set. Percent agriculture was positively correlated with relative dove abundance. Interestingly, we found a negative relationship between edge density and dove abundance. Researchers should conduct future research on dove nesting patterns in Mississippi and threshold levels of edge necessary to maximize dove density. During the last 20 years, Mississippi lost more than 800,000 ha of cropland while forest cover represented largely by pine (Pinus taeda) plantations increased by more than 364,000 ha. Our results suggest observed localized declines in mourning dove abundance in Mississippi may be related to the documented conversion of agricultural lands to pine plantations.

  6. An observation of a partially albinistic zenaida macroura (Mourning Dove)

    Berdeen, James; Otis, D.L.

    2011-01-01

    Abstract Three of the 4 forms of albinism that occur in avifauna have been detected in Zenaida macroura (Mourning Dove). Albinism is rare in this species, and the incidence rate of each age and sex cohort is not well known. Consequently, we examined the pigmentation of Mourning Doves encountered in the Coastal Plain of South Carolina, and classified the age and sex of all individuals. One adult male Mourning Dove had unusually light coloration of some feathers and the upper mandible. This pigmentation is consistent with partial albinism. This was the only individual out of 10,749 examined that appeared to be albinistic. This low incidence rate of albinism supports the conclusion that this condition is relatively rare in Mourning Doves (Mirarchi 1993).

  7. Haemoproteus, a blood parasite, in domestic pigeons and mourning doves in Maryland

    Knisley, J.O.; Herman, C.M.

    1967-01-01

    The occurrence of Haemoproteus in pigeons throughout the world and in mourning doves in the United States is reviewed. Haemoproteus has previously been reported only once from pigeons in Maryland. During this study it was found in all of 18 pigeons from one area but in none of 12 from an adjacent area. No infections were found in 90 Maryland mourning doves. All of the 10 mourning doves from Florida were infected whereas 60 nestlings from Texas and Mississippi had no parasites. None was found in 358 nestling white-winged doves from Texas.

  8. Using fecal glucocorticoids for stress assessment in Mourning Doves

    2003-01-01

    Fecal glucocorticoid assays provide a potentially useful, noninvasive means to study physiological responses of wildlife to various stressors. The objective of our study was to validate a method for measuring glucocorticoid metabolites in Mourning Dove (Zenaida macroura) feces. We validated the assay using standard procedures (e.g., parallelism, recovery of exogenous corticosterone) to demonstrate that the assay accurately and precisely measured glucocorticoid metabolites in Mourning Dove fecal extracts. We conducted adrenocorticotropin (ACTH) challenge experiments to validate the assay's ability to determine biologically important changes in fecal glucocorticoids. Fecal glucocorticoid levels increased significantly approximately 2-3 hr after administration of ACTH at 50 IU per kg body mass to wild Mourning Doves held in captivity. In contrast, fecal glucocorticoid metabolites did not increase in control birds, birds that received saline injections, or a lower dose of ACTH (1 IU per kg body mass). Variation in overall fecal glucocorticoid metabolite levels may have been influenced by season and the length of time birds were held in captivity. Non-invasive fecal glucocorticoid metabolite analyses, in combination with demographic information, may have considerable utility for monitoring the effects of natural and anthropogenic disturbances on Mourning Dove populations.

  9. Mourning Dove nesting habitat and nest success in Central Missouri

    Drobney, R.D.; Schulz, J.H.; Sheriff, S.L.; Fuemmeler, W.J.

    1998-01-01

    Previous Mourning Dove (Zenaida macroura) nesting studies conducted in areas containing a mixture of edge and continuous habitats have focused on edge habitats. Consequently, little is known about the potential contribution of continuous habitats to dove production. In this study we evaluated the relative importance of these two extensive habitat types by monitoring the habitat use and nest success of 59 radio-marked doves during 1990-1991 in central Missouri. Of 83 nests initiated by our marked sample, most (81.9%) were located in edge habitats. Although continuous habitats were selected less as nest sites, the proportion of successful nests did not differ significantly from that in edge habitats. Our data indicate that continuous habitats should not be considered marginal nesting habitat. If the intensity of use and nest success that we observed are representative regionally or nationally, continuous habitats could contribute substantially to annual Mourning Dove production because of the high availability of these habitats throughout much of the Mourning Dove breeding range.

  10. Aging mourning doves by outer primary wear

    Science.gov (United States)

    Wight, H.M.; Blankenship, L.H.; Tomlinson, R.E.

    1967-01-01

    Many immature mourning doves (Zenaidura macroura) cannot be aged by the conventional white-tipped primary covert method if molt has proceeded beyond the 7th primary. A new method of aging doves in this group is based on the presence (immature) or absence (adult) of a buff-colored fringe on the tips of the 9th and 10th primaries. Experienced biologists were nearly 100 percent accurate in aging wings of 100 known-age doves from eastern and midwestern states. The technique is not as reliable for doves from southwestern United States because of added feather wear, apparently from harsh vegetative and soil conditions.

    1978-01-01

    Results confirmed pairing as the primary factor influencing perch-cooing rates of wild mourning doves (Zenaida macroura). Marked unmated males cooed at substantially higher rates (6.2x) than mated males, had greater probability of cooing (2.3x) during 3-minute periods, and continued cooing longer each morning than mated males. Population density was not a major factor affecting cooing. Unmated males cooed more frequently in the presence of other cooing doves (P < 0.05) than when alone, but the number of additional doves above 1 was unimportant. Cooing rates of both mated and unmated males on areas with dissimilar dove densities were not significantly different. Within limits of standard call-count procedure, weather exerted no detectable influence on cooing.

  13. Primary feather molt of adult mourning doves in North and South Carolina

    Science.gov (United States)

    Haas, G.H.; Amend, S.R.

    1979-01-01

    Examination of 8,141 adult mourning doves (Zenaida macroura) in North and South Carolina revealed that substantial numbers complete primary feather molt in September. Adult mourning doves shed primaries at the rate of 1 per 14 days. No difference was found in this rate between sexes or among years, 1969-74. The initiation of molt differed from year to year, and female molt always preceded male molt. Available data show that southern doves complete primary molt a month earlier than northern doves. Therefore, age based on primary molt can be biased upward if all molt-complete wings from southern hunting samples are considered immature.

    1971-01-01

    Eggs (n = 452) of the mourning dove (Zenaidura macroura) were collected from 9 states in 1969 and 11 states in 1970, and shell thickness was compared with that of eggs (n = 97) collected from 24 states during the years 1861 to 1935. Mean shell thickness did not differ significantly in the test groups.

  15. Evaluating call-count procedures for measuring local mourning dove populations

    Science.gov (United States)

    Armbruster, M.J.; Baskett, T.S.; Goforth, W.R.; Sadler, K.C.

    1978-01-01

    Seventy-nine mourning dove call-count runs were made on a 32-km route in Osage County, Missouri, May 1-August 31, 1971 and 1972. Circular study areas, each 61 ha, surrounding stop numbers 4 and 5, were delineated for intensive nest searches and population estimates. Tallies of cooing male doves along the entire call-count route were quite variable in repeated runs, fluctuating as much as 50 percent on consecutive days. There were no consistent relationships between numbers of cooing males tallied at stops 4 and 5 and the numbers of current nests or doves estimated to be present in the surrounding study areas. We doubt the suitability of call-count procedures to estimate precisely the densities of breeding pairs, nests or production of doves on small areas. Our findings do not dispute the usefulness of the national call-count survey as an index to relative densities of mourning doves during the breeding season over large portions of the United States, or as an index to annual population trends.

  16. Unretrieved shooting loss of mourning doves in north-central South Carolina

    Science.gov (United States)

    Haas, G.H.

    1977-01-01

    Unretrieved loss for mourning doves (Zenaida macroura) in north-central South Carolina was between 27 and 41 percent of the retrieved kill for the 1973 through 1975 hunting seasons based on 1,396 doves shot by 281 hunters. Dove hunters hunted in groups, fired 8.6 shots per retrieved dove, and engaged in a substantial number of illegal activities. Increased dove populations and hunter bag resulted in increased unretrieved loss, numbers of shots per bagged bird, and illegal activities. Retriever dogs increased the efficiency of dove hunters.

  17. Survival models for harvest management of mourning dove populations

    Science.gov (United States)

    Otis, D.L.

    2002-01-01

    Quantitative models of the relationship between annual survival and harvest rate of migratory game-bird populations are essential to science-based harvest management strategies. I used the best available band-recovery and harvest data for mourning doves (Zenaida macroura) to build a set of models based on different assumptions about compensatory harvest mortality. Although these models suffer from lack of contemporary data, they can be used in development of an initial set of population models that synthesize existing demographic data on a management-unit scale, and serve as a tool for prioritization of population demographic information needs. Credible harvest management plans for mourning dove populations will require a long-term commitment to population monitoring and iterative population analysis.

  18. A new stratification of mourning dove call-count routes

    Science.gov (United States)

    Blankenship, L.H.; Humphrey, A.B.; MacDonald, D.

    1971-01-01

    The mourning dove (Zenaidura macroura) call-count survey is a nationwide audio-census of breeding mourning doves. Recent analyses of the call-count routes have utilized a stratification based upon physiographic regions of the United States. An analysis of 5 years of call-count data, based upon stratification using potential natural vegetation, has demonstrated that this uew stratification results in strata with greater homogeneity than the physiographic strata, provides lower error variance, and hence generates greatet precision in the analysis without an increase in call-count routes. Error variance was reduced approximately 30 percent for the contiguous United States. This indicates that future analysis based upon the new stratification will result in an increased ability to detect significant year-to-year changes.

  19. Importance of structural stability to success of mourning dove nests

    Science.gov (United States)

    Coon, R.A.; Nichols, J.D.; Percival, H.F.

    1981-01-01

    Studies of nest-site selection and nesting habitats often involve a "characterization" of nests and of habitats in which nests are found. Our objective in the present work is to identify nest-site characteristics that are associated with variation in components of Mourning Dove (Zenaida macroura) fitness (e.g. the probability of a nest succeeding), as opposed to simply "characterizing" dove nest sites. If certain nest- site characteristics affect the probability that a nest will succeed, then we suspect that these characteristics will be associated with either concealment (the probability of detection by certain predators) or structural stability (the probability of eggs or entire nests falling to the ground as a result of wind, rain storms, parental activity, etc.). Although other workers agree that structural stability is an important determinant of Mourning Dove nesting success (e.g. McClure 1944: 384; Woolfenden and Rohwer 1969: 59), we are aware of no actual tests of this hypothesis.

  20. Reward banding to determine reporting rate of recovered mourning dove bands

    Tomlinson, R.E.

    1968-01-01

    Reward bands placed on the other leg of certain regularly banded immature mourning doves (Zenaidura macroura) were used to develop information on reporting rates of recovered dove bands. Reports from 15 widely separated sections of the United States showed considerable variation in recovery rate of doves both with and without reward bands. The overall percentages of banded doves that were reported as recovered were 9.69% for those with reward bands and 3.83% for controls. The bandreporting rate for states influenced by publicity was 66%; that for states not influenced was 32%.

  1. Population demographics of two local South Carolina mourning dove populations

    Science.gov (United States)

    McGowan, D.P.; Otis, D.L.

    1998-01-01

    The mourning dove (Zenaida macroura) call-count index had a significant (P 2,300 doves and examined >6,000 individuals during harvest bag checks. An age-specific band recovery model with time- and area-specific recovery rates, and constant survival rates, was chosen for estimation via Akaike's Information Criterion (AIC), likelihood ratio, and goodness-of-fit criteria. After-hatching-year (AHY) annual survival rate was 0.359 (SE = 0.056), and hatching-year (HY) annual survival rate was 0.118 (SE = 0.042). Average estimated recruitment per adult female into the prehunting season population was 3.40 (SE = 1.25) and 2.32 (SE = 0.46) for the 2 study areas. Our movement data support earlier hypotheses of nonmigratory breeding and harvested populations in South Carolina. Low survival rates and estimated population growth rate in the study areas may be representative only of small-scale areas that are heavily managed for dove hunting. Source-sink theory was used to develop a model of region-wide populations that is composed of source areas with positive growth rates and sink areas of declining growth. We suggest management of mourning doves in the Southeast might benefit from improved understanding of local population dynamics, as opposed to regional-scale population demographics.

  2. Upper digestive tract trichomoniasis in mourning doves and other birds

    Science.gov (United States)

    Stabler, R.M.; Herman, C.M.

    1951-01-01

    This paper, while partially a review of previously published reports from North America, presents many new records on the occurrence of Trichomonas gallinae in North American columbiform birds. Evidence is presented that the .infection is present throughout most of the United States and on occasion has reached epizootic proportions in mourning doves and band-tiled pigeons in isolated areas. An extensive epizootic is reported involving several thousand eastern mourning doves in the Southeastern States during the summer of 1950. Although probably the chief means of transmission is from. parent to offspring in columbiform birds (and the occurrence of infection in nestling mourning doves demonstrates that this mode of inoculation occurs) in severe epizootics there also is undoubtedly a transmission by contamination of water or food besides, or as well as, the parent to offspring transfers. When T. gallinae is implanted in clean pigeons it becomes evident that there is a variety of strains of the organisms and that they differ considerably in virulence. Some strains may kill almost every recipient, while others, though they readily infect, never produce the slightest discomfort or pathology. Nonlethal infections produce an immunity to all strains tested. In some cases, however, when these double-strain infections are further inoculated into. clean birds, the effects of either the nonlethal or the killing strain may predominate. The mechanism by which this virulence acts in the blrds is undoubtedly an important factor in determining the morbidity or mortality that may occur in a population. The prevalence of trichomoniasis in native pigeons and doves presents many practical as well as academic problems. Ultimate application of control measures, evenon an experimental basis, must await further knowledge of many more basic facts.

  3. Spent shot availability and ingestion on areas managed for mourning doves

    2002-01-01

    Mourning dove (Zenaida macroura) hunting is becoming increasingly popular, especially in managed shooting fields. Given the possible increase in the availability of lead (Pb) shot on these areas, our objective was to estimate availability and ingestion of spent shot at the Eagle Bluffs Conservation Area (EBCA, hunted with nontoxic shot) and the James A. Reed Memorial Wildlife Area (JARWA, hunted with Pb shot) in Missouri. During 1998, we collected soil samples one or 2 weeks prior to the hunting season (prehunt) and after 4 days of dove hunting (posthunt). We also collected information on number of doves harvested, number of shots fired, shotgun gauge, and shotshell size used. Dove carcasses were collected on both areas during 1998-99. At EBCA, 60 hunters deposited an estimated 64,775 pellets/ha of nontoxic shot on or around the managed field. At JARWA, approximately 1,086,275 pellets/ha of Pb shot were deposited by 728 hunters. Our posthunt estimates of spent-shot availability from soil sampling were 0 pellets/ha for EBCA and 6,342 pellets/ha for JARWA. Our findings suggest that existing soil sampling protocols may not provide accurate estimates of spent-shot availability in managed dove shooting fields. During 1998-99, 15 of 310 (4.8%) mourning doves collected from EBCA had ingested nontoxic shot. Of those doves, 6 (40.0%) contained a?Y7 shot pellets. In comparison, only 2 of 574 (0.3%) doves collected from JARWA had ingested Pb shot. Because a greater proportion of doves ingested multiple steel pellets compared to Pb pellets, we suggest that doves feeding in fields hunted with Pb shot may succumb to acute Pb toxicosis and thus become unavailable to harvest, resulting in an underestimate of ingestion rates. Although further research is needed to test this hypothesis, our findings may partially explain why previous studies have shown few doves with ingested Pb shot despite their feeding on areas with high Pb shot availability.

  4. Immunologic status of mourning doves following an epizootic of trichomoniasis

    Science.gov (United States)

    Kocan, R.M.; Amend, S.R.

    1972-01-01

    An epizootic of trichomoniasis in mourning doves at the Carolina Sandhills National Wildlife Refuge began in 1969 and continued into 1970. The disease was seen in 16% of the adults and 2% of the immatures in 1970, but only one immature bird out of 37 surveyed (3%) carried Trichomonas gallinae. Challenge infection of 33 doves from the epizootic area showed 85 percent to be resistant to trichomoniasis, compared to 69 percent resistance in doves from Maryland, where no epizootic has occurred for at least 3 years. Plasma protein changes which occurred following challenge infection were identical in CSNWR and Maryland doves which showed evidence of disease. Of the doves which showed no signs of disease, those from the CSNWR exhibited no change in beta globulins, identical to the response in pigeons which survive an infection by T. gallinae, but they had some tissue invasion by the parasite.

  5. Rapid change in the defense of flightless young by a mourning dove parent

    Science.gov (United States)

    Berdeen, James; Otis, D.L.

    2011-01-01

    We report that an adult-sized Zenaida macroura (Mourning Dove), presumably a parent, rapidly decreased risk taken in defense of a juvenile as the likelihood of predation to the juvenile increased. We attribute this decrease in risk taken to (1) the parent's perception that the risk of predation had increased to the extent that a continuation of defensive behaviors would not prevent the death of the juvenile, and (2) its attempt to minimize its own risk of death. It may be that there is a threshold beyond which Mourning Dove parents will forgo the risk of additional defense of offspring in favor of making another reproductive attempt.

  6. Changes in land use as a possible factor in Mourning Dove population decline in Central Utah

    Ostrand, William D.; Meyers, P.M.; Bissonette, J.A.; Conover, M.R.

    1998-01-01

    Mourning Dove (Zenaida macroura) population indices for the western United States have declined significantly since 1966. Based on data collected in 1951-1952, in Fillmore, Utah, we examined whether there had been a local decline in the dove population index since the original data were collected. We then determined whether habitat had been altered, identified which foraging habitats doves preferred, and assessed whether changes in land use could be responsible, in part, for a decline in the local population index. We found that dove population indices declined 72% and 82% from 1952-1992 and 1952-1993, respectively. The most dramatic change in habitat was an 82% decline in land devoted to dry land winter wheat production and a decline in livestock feed pens. Doves foraged primarily in harvested wheat fields, feed pens, and weedy patches. We hypothesize that a decrease in wheat availability during the spring and the consolidation of the livestock industry have contributed to a population decline of Mourning Doves in central Utah.

    Burger, J.; Kennamer, R.A.; Brisbin, I.L. Jr.; Gochfeld, M.

    1998-01-01

    Recreational and subsistence hunters and anglers consume a wide range of species, including birds, mammals, fish and shellfish, some of which represent significant exposure pathways for environmental toxic agents. This study focuses on the Department of Energy's (DOE's) Savannah River Site (SRS), a former nuclear weapons production facility in South Carolina. The potential risk of contaminant intake from consuming mourning doves (Zenaida macroura), the most popular United States game bird, was examined under various risk scenarios. For all of these scenarios the authors used the mean tissue concentration of six metals (lead, mercury, cadmium, selenium, chromium, manganese) and radiocesium, in doves collected on and near SRS. They also estimated risk to a child consuming doves that had the maximum contaminant level. The authors used the cancer slope factor for radiocesium, the Environmental Protection Agencies Uptake/Biokinetic model for lead, and published reference doses for the other metals. As a result of their risk assessments they recommend management of water levels in contaminated reservoirs so that lake bed sediments are not exposed to use by gamebirds and other terrestrial wildlife. Particularly, measures should be taken to insure that the hunting public does not h ave access to such a site. Their data also indicate that doves on popular hunting areas are exposed to excess lead, suggesting that banning lead shot for doves, as has been done for waterfowl, is desirable

  9. Mourning dove population trend estimates from Call-Count and North American Breeding Bird Surveys

    Sauer, J.R.; Dolton, D.D.; Droege, S.

    1994-01-01

    The mourning dove (Zenaida macroura) Callcount Survey and the North American Breeding Bird Survey provide information on population trends of mourning doves throughout the continental United States. Because surveys are an integral part of the development of hunting regulations, a need exists to determine which survey provides precise information. We estimated population trends from 1966 to 1988 by state and dove management unit, and assessed the relative efficiency of each survey. Estimates of population trend differ (P lt 0.05) between surveys in 11 of 48 states; 9 of 11 states with divergent results occur in the Eastern Management Unit. Differences were probably a consequence of smaller sample sizes in the Callcount Survey. The Breeding Bird Survey generally provided trend estimates with smaller variances than did the Callcount Survey. Although the Callcount Survey probably provides more withinroute accuracy because of survey methods and timing, the Breeding Bird Survey has a larger sample size of survey routes and greater consistency of coverage in the Eastern Unit.

  10. Mourning dove hunting regulation strategy based on annual harvest statistics and banding data

    Otis, D.L.

    2006-01-01

    Although managers should strive to base game bird harvest management strategies on mechanistic population models, monitoring programs required to build and continuously update these models may not be in place. Alternatively, If estimates of total harvest and harvest rates are available, then population estimates derived from these harvest data can serve as the basis for making hunting regulation decisions based on population growth rates derived from these estimates. I present a statistically rigorous approach for regulation decision-making using a hypothesis-testing framework and an assumed framework of 3 hunting regulation alternatives. I illustrate and evaluate the technique with historical data on the mid-continent mallard (Anas platyrhynchos) population. I evaluate the statistical properties of the hypothesis-testing framework using the best available data on mourning doves (Zenaida macroura). I use these results to discuss practical implementation of the technique as an interim harvest strategy for mourning doves until reliable mechanistic population models and associated monitoring programs are developed.

    Distinct acoustic whistles are associated with the wing-beats of many doves, and are especially noticeable when doves ascend from the ground when startled. I thus hypothesized that these sounds may be used by flock-mates as cues of potential danger. To test this hypothesis, I compared the responses of mourning doves ( Zenaida macroura), northern cardinals ( Cardinalis cardinalis), and house sparrows ( Passer domesticus) to audio playbacks of dove ‘startle wing-whistles’, cardinal alarm calls, dove ‘nonstartle wing-whistles’, and sparrow ‘social chatter’. Following playbacks of startle wing-whistles and alarm calls, conspecifics and heterospecifics startled and increased vigilance more than after playbacks of other sounds. Also, the latency to return to feeding was greater following playbacks of startle wing-whistles and alarm calls than following playbacks of other sounds. These results suggest that both conspecifics and heterospecifics may attend to dove wing-whistles in decisions related to antipredator behaviors. Whether the sounds of dove wing-whistles are intentionally produced signals warrants further testing.

    Riparian forests of the American Southwest are especially prone to changes in composition and structure due to natural and anthropogenic factors. To determine how breeding mourning doves (Zenaida macroura) respond to these changes, we examined nest site use and nest survival in control plots, fuel reduction plots before and after mechanical thinning, and post-wildfire...

    We examined results from the first national-scale effort to estimate mourning dove (Zenaida macroura) age ratios and developed a simple, efficient, and generalizable methodology for calibrating estimates. Our method predicted age classes of unknown-age wings based on backward projection of molt distributions from fall harvest collections to preseason banding. We estimated 1) the proportion of late-molt individuals in each age class, and 2) the molt rates of juvenile and adult birds. Monte Carlo simulations demonstrated our estimator was minimally biased. We estimated model parameters using 96,811 wings collected from hunters and 42,189 birds banded during preseason from 68 collection blocks in 22 states during the 2005–2007 hunting seasons. We also used estimates to derive a correction factor, based on latitude and longitude of samples, which can be applied to future surveys. We estimated differential vulnerability of age classes to harvest using data from banded birds and applied that to harvest age ratios to estimate population age ratios. Average, uncorrected age ratio of known-age wings for states that allow hunting was 2.25 (SD 0.85) juveniles:adult, and average, corrected ratio was 1.91 (SD 0.68), as determined from harvest age ratios from an independent sample of 41,084 wings collected from random hunters in 2007 and 2008. We used an independent estimate of differential vulnerability to adjust corrected harvest age ratios and estimated the average population age ratio as 1.45 (SD 0.52), a direct measure of recruitment rates. Average annual recruitment rates were highest east of the Mississippi River and in the northwestern United States, with lower rates between. Our results demonstrate a robust methodology for calibrating recruitment estimates for mourning doves and represent the first large-scale estimates of recruitment for the species. Our methods can be used by managers to correct future harvest survey data to generate recruitment estimates for use in

  15. Re-analysis of a banding study to test the effects of an experimental increase in bag limits of mourning doves

    In 1966-1971, eastern US states with hunting seasons on mourning doves (Zenaida macroura) participated in a study designed to estimate the effects of bag limit increases on population survival rates. More than 400 000 adult and juvenile birds were banded and released during this period, and subsequent harvest and return of bands, together with total harvest estimates from mail and telephone surveys of hunters, provided the database for analysis. The original analysis used an ANOVA framework, and resulted in inferences of no effect of bag limit increase on population parameters (Hayne 1975). We used a logistic regression analysis to infer that the bag limit increase did not cause a biologically significant increase in harvest rate and thus the experiment could not provide any insight into the relationship between harvest and annual survival rates. Harvest rate estimates of breeding populations from geographical subregions were used as covariates in a Program MARK analysis and revealed an association between annual survival and harvest rates, although this relationship is potentially confounded by a latitudinal gradient in survival rates of dove populations. We discuss methodological problems encountered in the analysis of these data, and provide recommendations for future studies of the relationship between harvest and annual survival rates of mourning dove populations.

  16. A comparison of the nesting success of mourning doves and American robins in conventionally managed and organic orchards

    1992-01-01

    A comparative study was undertaken to document more closely the effects of operational pesticide use on non-target avian species. Mourning Dove (Zenaida macroura) and American Robin (Turdus migratorius) nesting activity was monitored in three organic and three conventional orchards during two breeding seasons. Surveys were conducted to characterize the avian community within orchards under both management practices. Organophosphorus (OP) and carbamate pesticides, known to be extremely toxic to birds, were repeatedly sprayed during the peaks in dove and robin breeding activity. Spray card tests revealed that OP pesticides were deposited on 85.5% of the nests tested during routine spray operations. The threat of direct pesticide exposure to eggs, nestlings, and adult birds was considerable. Nest daily survival rates (DSRs) for both doves and robins, were significantly higher in the organic orchards than in the conventional orchards in 1991 and years combined (P < 0.05). Species diversity was significantly greater in the organic orchards (H = 2.43) than in the conventional orchards (H = 1.79). Results suggest that repeated applications of pesticides, within the conventional orchards, directly or indirectly, affected the reproductive success of doves and robins, as well as influenced species diversity within the treated orchards. Organic orchards appear to provide more favorable nesting and foraging habitat for birds than conventional orchards.

    We examined 115 hunter-killed mourning doves (Zenaida macroura) from 4 states (Arizona, Pennsylvania, South Carolina, and Tennessee, U.S.A.) in 1998 and 1999 to investigate geographical variation in the prevalence and intensity of intestinal helminth infections. Four intestinal helminth species were identified: Killigrewia delafondi, Ornithostrongylus crami, Ascaridia columbae, and Capillaria obsignata. The number of worms (all helminth species combined) per infected bird ranged from 1 to 166 (mean ± SE = 12.7 ± 7.45, median = 2.0). Filarids. Aproctella stoddardi, were found in 2 birds but were probably adhering to the outside of the intestine. Overall, 18% of the doves were infected with 1 or more species of helminths. The percentage of doves infected with at least 1 helminth species varied from 4% in Arizona to 27% in South Carolina. Mixed infections occurred in only 3 individuals (14% of infected birds). We found no significant differences in prevalence of infection among any of the 4 helminths by host age or sex, and prevalences were too low to test for differences among states. The intensity of O. crami was higher in males than in females but did not differ significantly among states. Intensities of the other 3 helminths did not differ by sex or state, and we found no differences in helminth intensity by age. Intestinal length was significantly greater in infected than in uninfected birds.

  18. Individual variation in baseline and stress-induced corticosterone and prolactin levels predicts parental effort by nesting mourning doves

    2009-01-01

    Endocrine systems have an important mechanistic role in structuring life-history trade-offs. During breeding, individual variation in prolactin (PRL) and corticosterone (CORT) levels affects behavioral and physiological processes that drive trade-offs between reproduction and self-maintenance. We examined patterns in baseline (BL) and stress induced (SI; level following a standard capture-restraint protocol) levels of PRL and CORT for breeding mourning doves (Zenaida macroura). We determined whether the relationship of adult condition and parental effort to hormone levels in wild birds was consistent with life-history predictions. Both BL PRL and BL CORT level in adults were positively related to nestling weight at early nestling ages, consistent with the prediction of a positive relationship of hormone levels to current parental effort of adults and associated increased energy demand. Results are consistent with the two hormones acting together at baseline levels to limit negative effects of CORT on reproduction while maintaining beneficial effects such as increased foraging for nestling feeding. Our data did not support predictions that SI responses would vary in response to nestling or adult condition. The magnitude of CORT response in the parents to our capture-restraint protocol was negatively correlated with subsequent parental effort. Average nestling weights for adults with the highest SI CORT response were on average 10–15% lighter than expected for their age in follow-up visits after the stress event. Our results demonstrated a relationship between individual hormone levels and within population variation in parental effort and suggested that hormonal control plays an important role in structuring reproductive decisions for mourning doves.

    The Socorro dove Zenaida graysoni , endemic to Socorro Island, was last reported in the wild in 1972. Fortunately, the species has been propagated in zoos in Europe and the United States, and plans are under way to re-introduce it to its native habitat. This will be the first known attempt to return a bird species extinct in the wild to its ancestral island. In order to assess the disease threats the Socorro dove may face, the avifauna of Socorro Island, with a specific focus on Socorro ground doves Columbina passerina socorroensis and mourning doves Zenaida macroura , as well as Socorro doves in captivity, were screened for blood parasites of the genera Plasmodium , Haemoproteus, Leucocytozoon, and Trypanosoma spp. We found Haemoproteus spp. in 17 (74%) of 23 Socorro ground doves, 23 (92%) of 25 mourning doves, and 3 (14%) of 21 northern mockingbirds; none of the other bird species showed infections. Here, we report the phylogenetic analysis of 19 distinct lineages of Haemoproteus spp. detected in birds of Socorro Island and compare their evolutionary relationships to parasites detected in the avifauna of the Galápagos Islands, continental Latin America, and Europe. Microscopic examination revealed 1 mourning dove infected with Plasmodium ( Haemamoeba ), thus underscoring the importance of using both PCR and microscopy when analyzing avian blood samples for hemosporidian parasites. The study confirms that the Socorro dove will most likely be exposed to Haemoproteus spp. that currently infect mourning doves and Socorro ground doves of Socorro Island. A monitoring program for both birds and vectors should be implemented to establish the prevalence of Plasmodium sp. and as a necessary conservation measure for critically endangered birds on the island.

    1970-01-01

    The examination of 7,892 adult doves in Missouri between 1953 and 1965 showed that less than 2.5% of adult doves completed their molt before October 1. Adult doves of both sexes began molting their primary feathers during early June in Missouri and lost the last (tenth) primary during the latter half of October. Approximately 140-150 days were required to complete the molt. Thus, early-hatched immatures, which begin their primary molt 25-30 days after hatching, contributed the bulk of the wings with completed molts in September. By correctly classifying September samples of dove wings with a completed molt as young-of-the-year a more accurate young:adult ratio is obtained.

    Mourning dove (Zenaidura macroura) breast muscle samples from birds collected in 1970-71 from Rhode Island, Pennsylvania, Maryland, Missouri, Kentucky, Virginia, Arkansas, Tennessee, North Carolina, South Carolina, Mississippi, Alabama, Georgia, Louisiana, and Florida were found to contain residues of DDT, DDE, DDD, polychlorinated biphenyls, dieldrin, mirex, mercury, and heptachlor epoxide in amounts not considered hazardous to consumers, human or nonhuman. There were 145 birds involved, 7 to 10 from each State. Residues of DDT plus DDE plus DDD averaged 5.83 ppm lipid weight (0.068 ppm wet weight); those of PCB's, 9.75 ppm lipid weight (0.121 ppm wet weight); compounds were found in all birds. Heptachlor epoxide and dieldrin were found in little more than trace amounts: heptachlor in all birds, dieldrin in 73. Mirex was found only in birds from South Carolina, Georgia, and Florida, averaging 4.32 ppm lipid weight (0.046 ppm wet weight) in eight birds. Less than 0.05 ppm (wet weight) mercury was found in all birds except 10, in which it ranged from 0.07 to 0.67 ppm. The 10 were from Rhode Island, Pennsylvania, Maryland, Virginia, Tennessee, and Alabama.

  9. Mourning the dead, mourning the disappeared: the enigma of the absent-presence.

    Taiana, Cecilia

    2014-12-01

    Freud's interest in the impact of death on the living goes back further than Mourning and Melancholia (1917e, [1915]). In Totem and Taboo (1912-13) Freud noted the ambivalence of the emotions we experience in relation to the dead. In this paper, I focus on Mourning and Melancholia as a landmark in the understanding of both the normal and psychopathological aspects of mourning and depressive processes in human beings. Mourning and Melancholia bridges Freud's first and second topographic theories of the psychic apparatus and constitutes for many authors the foundation of his theory of internal object relations. With this psychoanalytic understanding of mourning as a framework, I discuss 'special mourning processes,' such as the those confronted by psychoanalysts in Argentina when treating the relatives of thousands of people who were 'disappeared' by the military dictatorship in the 1970s; they are 'special' in the sense that the external reality [which] constitutes the starting point of the psychic mourning process, as described by Freud, is absent. I argue that the 'absent-presence' of the body as an enigmatic message initiates a special mourning process that bears certain characteristics of, and is isomorphic to, Laplanche's seduction theory.

  10. Paradoxes of maternal mourning.

    Science.gov (United States)

    Brice, C W

    1991-02-01

    It has been customary to conceptualize mourning as a phasic or stage phenomenon (Lindemann 1944; Parkes 1972; Bowlby 1980; Knapp 1986). Such a conceptualization has proved to be of tremendous didactic value, especially in terms of succinctly organizing and communicating the major affects, behaviors, and reactions of mourning. It is, however, my belief, based upon clinical experience with many forms of bereavement, that the phenomenon of mourning is not comprised of clearly delineated stages and phases. I have come to conceptualize the phenomenon of mourning the death of a loved person as involving the bereaved's struggle with a series of more or less unresolvable paradoxes rather than as a progression through stages that possess relatively distinct and predictable beginning and ending points. The specific paradoxes encountered by a bereaved person differ, of course, in accordance with the relationship that was lost (mother, father, spouse, child, or sibling), the developmental stage of the bereaved (childhood, adolescence, adulthood, or maturity), the type of death (sudden or prolonged), and the cause of death (illness, murder, suicide, or accident). In this paper, I will address those paradoxes that seem specific to maternal mourning - that is, to mothers who are mourning the death of a child.

    Full Text Available Motives for preparing this paper, are personal and professional, there is mutual interference. Ending of the paper is considered as synchronicity, in author s personal mourning. A mourning, as hard experience, but also as a chance for development, integration of somebody s own capacities, embodied in relationship with another, is close connected with individuation, that is represented as spontaneous, unconcious process of self development of personality with the aim of searching unity and wholesness of personality, following number of compensations toward balance and wholesness as final aim, but also is considered as ideal. In close conection with individuation is transcedental function that integrates conscious and unconcsious attitude, overcomes struggle of consiousness and unconsciousness. In paper, there are examples of two myths, myth about Demetra and Persefona, and Orpheus and Euridica, that show possible individuation directions throughout mourning process. Individation is, there, put in the context of death and Under World. Beside individual, there is consideration of colective mourning, although that approach is restricted for some reasons. There is question of capacity of society for mourning.

  12. The missing tombstone: reflections on mourning and creativity.

    Science.gov (United States)

    Ornstein, Anna

    2010-08-01

    There are differences as well as similarities between mourning occurring after the loss of a single individual under ordinary civilized conditions, and mourning after multiple losses under traumatic conditions. A brief review of the psychoanalytic theory of mourning articulated by Freud in 1917 and modified in the 1960s is followed by an equally brief review of the relationship between artistic creativity and mourning. Because survivors of major disasters who suffer multiple losses need time to recover before they can engage the emotionally demanding task of mourning, the mourning process in these cases is frequently delayed. "Memorial spaces" appear to facilitate delayed mourning because such spaces are responsive to a deeply felt need by survivors of major tragedies to articulate what they experience as unspeakable and unshareable. The memories and the pain associated with them are then welcome because mourning is not about forgetting; mourning is about remembering, a process that may take a lifetime.

    Though a young child cannot mourn like an adult, optimal responses may be distinguished from pathological ones and used to define "childhood mourning." Aspects of mourning such as identification and decathexis must be related to the child's developmental level. Creative use of an "imaginary parent" may help master a parent loss.

  14. Mourning beyond melancholia: Freud's psychoanalysis of loss.

    Science.gov (United States)

    Clewell, Tammy

    2004-01-01

    Freud's mourning theory has been criticized for assuming a model of subjectivity based on a strongly bounded form of individuation. This model informs "Mourning and Melancholia" (1917), in which Freud argued that mourning comes to a decisive end when the subject severs its emotional attachment to the lost one and reinvests the free libido in a new object. Yet Freud revised his mourning theory in writings concerned with the Great War and in The Ego and the Id (1923), where he redefined the identification process previously associated with melancholia as an integral component of mourning. By viewing the character of the ego as an elegiac formation, that is, as "a precipitate of abandoned object-cathexes," Freud's later work registers the endlessness of normal grieving; however, it also imports into mourning the violent characteristics of melancholia, the internal acts of moralized aggression waged in an effort to dissolve the internal trace of the other and establish an autonomous identity. Because it is not immediately clear how Freud's text offers a theory of mourning beyond melancholy violence, his account of the elegiac ego is shown here to ultimately undermine the wish for an identity unencumbered by the claims of the lost other and the past, and to suggest the affirmative and ethical aspects of mourning.

    Since depression, according to OMS, is such a worldwide condition, it is necessary to be able to distinguish a normal mourning from a pathological mourning and a depression, so as to qualify patients and health professionals to be able to support a normal mourning without medicating it nor hurrying (hasting) it, as well as being able to treat a depression adequately when it appears as a complication. Attachment theory focuses on mourning after loss with notions such as 1- acceptance of search for the lost person as a normal fact; 2- that mourning in children may have non-pathological outcomes; 3- that a non-processed mourning may be transmitted in an intergenerational way, and 4- also defines which elements may determine a pathological mourning or a depression. A clinical case is presented with an analysis of these notions.

    2007-01-01

    Depression and suicidality after first episode of psychosis are well-documented responses in patients with schizophrenia (Addington, Williams, Young, & Addington, 2004). The understanding of depression and suicidality has been increasingly refined through careful study. Researchers have identified a number of factors that may cause depression such as insight into the illness, feelings of loss and inferiority about the illness as a damaging life event, hopelessness about having a viable future with the illness and mourning for losses engendered by the illness. The authors argue that grief and mourning are not just an occasional reaction to the diagnosis of schizophrenia, but are a necessary part of coming to terms with having the illness. They offer three case examples, each of which illuminates a distinct way in which psychosis and mourning may be related--psychosis as a loss of former identity, psychosis as offering meaning and transformation, and psychosis as a way of coping with the inability to mourn. In their view, recovery depends on mourning illness-related losses, developing personal meaning for the illness, and moving forward with "usable insight" and new identity (Lewis, 2004) that reflects a new understanding of one's strengths and limitations with the illness.

    The author attempts to develop some of the basic models and concepts relating to mourning processes in psychotic patients on the assumption that situations of loss and mourning are key moments for psychoanalysis, psychotherapy, and therapeutic approaches in general. Secondly, he reminds us that 'mourning processes in psychotics' are not always 'psychotic mourning processes', that is to say, that they do not necessarily occur within, or give rise to, a psychotic clinical picture. These ideas are illustrated by a number of sessions and vignettes concerning two psychotic patients in psychotherapeutic and psychoanalytic treatment. In theoretical terms, it seems vitally important in this context to combine a relationship-based approach within a framework of special psychoanalytic psychopathology with an updated view of processes of mourning and affective loss. A fundamental requirement at clinical level is to determine the role to be played by psychoanalytically based treatments in combined, integrated or global therapies when working with psychotic patients. For this purpose, the paper ends by outlining a set of principles and objectives for such treatments. Copyright © 2010 Institute of Psychoanalysis.

    2012-09-01

    African mourning of loss of lives in South Africa has been shaped by discursive practices of both traditional African cultures and the sociopolitical developments under apartheid and in post-apartheid South Africa. This article reports on changes in mourning practices on the basis of a literature review and uses a collection of examples to highlight the navigation of some cultural and gendered issues relating to mourning, against the backdrop of the everyday experiences of loss of life in South Africa due to violence and HIV/AIDS. The article draws on African womanist and feminist scholarship and focuses on the intersections between cultural and gender practices of bereavement in the lives of professional urban African women. The authors argue for the use of positioning theory and witnessing practices to honor and story the ongoing struggle of African women as these women take different agentic positions by accepting, questioning, resisting, and/or changing cultural mourning practices while they compassionately witness the self and others in the narratives they live.

    A bereavement during pregnancy is difficult to mourn: a pregnant woman is so increasingly preoccupied with the new life that mourning is interrupted and often impossible to resume later. This may lead to idealisation of the child as a reincarnation of the dead person or child abuse. A bereaved woman should be helped to mourn at the time of death and to keep alive the expectation of future mourning once her baby is thriving. PMID:572731

    Grief is a natural part of life and it is always individual. Researchers have tried and still try to develop different theories to interpret, explain, and approach this particular phenomenon. The aim of the authors was to review the theoretical literature of mourning and to present new bereavement theories for domestic professionals. From the first half of the 20th century until presently mourning theories have undergone significant changes. Today the determinant models includes the flexible, coping-oriented dual process model, meaning reconstruction model which focuses on the meaning making, and the model which focuses on the development after the loss. The authors conclude that experts, who work in the clinical area should know the prevailing theories of grief, because they encounter often with loss at work. The presented models may contribute to more efficient work, to better understanding of the mourning process and to a better support of families.

    Death is an event that always breaks into family life in a surprising way. Of all the deaths, suicide is the one which more strongly questions the functionality of a family and increases the risk of difficulties in the mourning process. Families in which a suicide has occurred are exposed to a greater possibility of disintegration, disorganization and pathological expressions in their members. To present a reduced and circumscribed narrative revision, restricted to examine the relationship between suicide and the mourning process in the family. The suicide of a loved one is an event that may contribute to pathological grief and mental dysfunctions in surviving relatives. Death in the family is a natural phenomenon. However, death by suicide is one of the phenomena that can generate more alterations in the structure and organization of the family, due to the difficulty related to the mourning process.

    Data are summarized from a 10 year study of the Zenaida Dove (Zenaida aurita) in Puerto Rico and its offshore islands. The dove displays sexual size dimorphism, with males generally larger than females: Most activities (feeding, courtship, fighting) occurred in mornings and afternoons, whereas loafing and maintenance activities were more prevalent at mid-day. I recorded 77 plant species used as food by Zenaida Doves in Puerto Rico. Major food species uncluded Scleria lithosperma, Argemone mexicana, Croton rigidus, Phyllanthus amarus, Cordia angustifolia, Zanthoxylum martinicense, Euphorbia heterophylla, and several species of legumes. Zenaida Doves have two major vocalizations: the 'Coo', or Advertisement Call, given in assertive and sexual contexts, and the Nest Call, primarily used at or near the nest. Doves nested in a wide variety of habitats, including forest edge, mangrove forest, dry scrub, and mixed agriculture-urban areas. Nests were generally placed in trees, but doves nested on the ground where certain terrestrial predators were absent. Nests were found in all months of the year, although a breeding peak occurred from March through Mayor July. Doves replaced clutches when nests were destroyed, and recycled up to four times in a season. Males selected nest sites and initiated building. Eggs (2) were laid on alternate days, beginning about two days after the nest was completed. Incubation and nestling stages averaged 13.9 :t 0.5 [SE] and 14.3 :t 0.6 days. The male attended the nest from mid-morning (X = 08:59 hr) through mid-afternoon (x = 16:53), then the female took over incubation and brooding duties for the night. Nests were continuously covered from the laying of the first egg through day seven of the nestling stage. Thereafter, adult attendance dropped steadily until day 14, when they carne to the nest only for chick feedings. Chicks (days 0-15) showed a mean daily weight gain of 18.3% and attained a fledging weight of about 120g (81% of adult weight

    Full Text Available Derrida’s highly personal mourning texts are collected and published in a unique book under the title The Work of Mourning edited by Pascale-Anne Brault and Michael Naas, two outstanding translators of Derrida’s works. The English collection is published in 2001, while the French edition came out later in 2003 titled Chaque fois unique, la fin du monde (Each Time Unique, the End of the World. In his deconstructed eulogies, Derrida, being in accordance with ‘the mission impossible’ of deconstruction, namely, ‘to allow the coming of the entirely other’ in its otherness, seems to find his own voice. In my paper, I will focus on this special segment of Derrida’s death-work (cf. life-work; namely, on his mourning texts written for his dead friends, paying special attention to the rhetoric ‘circling around’ fidelity, friendship, and the other in his textual mourning.

    This paper connects the work of Melanie Klein on mourning to the pastor's work with the grief sufferer. Klein holds that mourning is an illness of manic depressive character rooted in infantile development. Klein's description of manic defenses in the face of loss has adult behavioral analogues with which the pastor must deal to bring mourning to resolution.

  10. Survival, fidelity, and recovery rates of white-winged doves in Texas

    KAUST Repository

    Collier, Bret A.

    2012-03-12

    Management of migratory birds at the national level has historically relied on regulatory boundaries for definition of harvest restrictions and estimation of demographic parameters. Most species of migratory game birds are not expanding their ranges, so migratory corridors are approximately fixed. White-winged doves (Zenaida asiatica), however, have undergone significant variation in population structure with marked range expansion occurring in Texas, and range contraction in Arizona, during the last 30 years. Because >85% of white-winged dove harvest in the United States (approx. 1.3 million annually) now occurs in Texas, information on vital rates of expanding white-winged dove populations is necessary for informed management. We used band recovery and mark-recapture data to investigate variation in survival and harvest across 3 geographic strata for white-winged doves banded in the pre-hunting season in Texas during 2007-2010. We banded 60,742 white-winged doves, recovered 2,458 bands via harvest reporting, and recaptured 455 known-age birds between 2007 and 2010. The best supporting model found some evidence for geographic differences in survival rates among strata (A-C) in both hatch-year (juvenile; A = 0.205 [SE = 0.0476], B = 0.213 [SE = 0.0278], C = 0.364 [SE = 0.0254]) and after-hatch year (adult; A = 0.483 [SE = 0.0775], B = 0.465 [SE = 0.0366], C = 0.538 [SE = 0.251]) birds. White-winged doves had a low probability of moving among strata (0.009) or being recaptured (0.002) across all strata. Harvest recovery rates were concordant with estimates for other dove species, but were variable across geographic strata. Based on our results, harvest management strategies for white-winged doves in Texas and elsewhere should consider differences in population vital rates among geographic strata. © 2012 The Wildlife Society.

  13. Anna Freud and the Holocaust: mourning and survival guilt.

    Science.gov (United States)

    Hartman, John J

    2014-12-01

    This article explores the period of Anna Freud's life after she was informed of the deaths of her aunts in Nazi concentration camps during World War II. Understanding of this period may be enhanced by consideration of the role of the Holocaust in her complicated mourning process. A series of her dreams is re-examined from the point of view of survivor guilt and the complicated mourning of her father in the context of the Holocaust. It is argued that unconscious reproaches against her father led to an identification with him that included his 'decision' to leave his sisters in Vienna. Survivor guilt in relation to her aunts' murders is seen as one of the complicating factors in the mourning process. In addition the article discusses the possible role of this period, particularly her work with child concentration camp survivors, in her post-war writing. The noted duality in her work between innovation and conservatism is explored in terms of an outcome of the mourning process of this period. It is argued that her views on mourning, trauma, attachment, and the widening scope of indications for psychoanalysis were influenced by the outcome of her mourning process. Finally, an irony is noted in the fact that her attitude about altruism never changed despite the role of the altruism of others in her rescue from the Nazis.

  16. Lead concentrations in the bones of city and country doves

    Energy Technology Data Exchange (ETDEWEB)

    Siegfried, W.R.; Frost, P.G.H.; Redelinghuys, E.P.; van der Merwe, R.P.

    The lead content of bones of laughing doves Streptopelia senegalensis was assayed by means of atomic absorption spectrophotometry. A significant difference in the mean lead content was found between two groups of wild doves. The one group was taken in the city of Cape Town, and the other group 50 km away in rural farmland near Stellenbosch. The bones of the urban doves contained on average seven times more lead per unit weight of tissue than those of their rural con-specifics. Concentrations of lead in the bones of rural and urban doves are approximately 70% and 80% below those recorded for corresponding pigeon Columba livia populations in Pennsylvania, USA. These differences between urban and rural populations are believed to reflect the relatively greater degree of lead in the atmosphere of the urban environment, presumably as a result of motor car exhaust emissions. 2 references, 1 table.

  18. Unresolved mourning, supernatural beliefs and dissociation: a mediation analysis.

    Science.gov (United States)

    Thomson, Paula; Jaque, S Victoria

    2014-01-01

    Unresolved mourning is marked by disorganized behavior and states of mind. In this study, we speculated that pathological dissociation would mediate the effects of unresolved mourning on supernatural beliefs. This hypothesis was determined based on findings that indicate an association between higher levels of dissociation, stronger beliefs in the supernatural and unresolved mourning. We examined two groups of participants, one classified as non-unresolved (non-U) (n = 56) and the other as unresolved (n = 26) (U) with respect to past loss/trauma as measured by the Adult Attachment Interview (AAI). Two self-report instruments were administered to measure supernatural beliefs and dissociation. As hypothesized, the multivariate analysis of variance indicated mean differences between the two groups. The unresolved group had greater belief in the supernatural and more pathological dissociative processes. The mediation analysis demonstrated that pathological dissociation fully mediated the effects of unresolved mourning on supernatural beliefs.

    Band recoveries provide requisite data for evaluating the spatial distribution of harvest relative to the distribution of breeding stocks for a wide variety of migratory species. We used direct and indirect band-recovery data to evaluate the distribution and derivation of harvest of white-winged doves (Zenaida asiatica) banded before hunting season in 3 distinct strata in Texas, USA, during 2007-2010. We banded 60,742 white-winged doves during 2007-2010, and based on 2,458 harvest recoveries, the majority (>95%) of white-winged dove harvest occurred during the first 2 months of the hunting season (Sep-Oct). Juvenile white-winged doves represented a greater percentage of the direct recoveries than adults across all strata (north = 80%, central = 69%, south = 82%) and the majority of direct band recoveries (north = 75%, central = 90%, south = 78%) occurred within the original banding strata. Age-specific weighting factors and harvest derivation indicated that both juvenile and adult harvest were highest within the strata of original banding. Harvest distribution data corrected for band-reporting rates indicated high fidelity of white-winged doves to specific geographic strata, with little interplay between strata. Our results suggest that population vital-rate estimates for survival and harvest for use in future Adaptive Harvest Management should focus on stock-specific levels. © 2012 The Wildlife Society.

  4. Effects of Divergent Selection Body Weight and the Quail Laying Eggs on some Physical and Mechanical Properties of Japanese Quail Eggs

    2016-08-01

    Full Text Available Introduction Breeding quail and quail egg industrial production because of the high nutritional value of these products has been developing these years. Considering the high demand and economical production, further development in the future is predicted. In order to design and effective utilization of the equipment for transportation, separation, packaging and storage, the physical and mechanical properties of quail eggs are needed. It is of great importance to study the factors which are influencing these properties. Strength of the shell is an important factor in determination of quail egg quality. Quail egg shell strength depends on several variables including specific gravity, egg weight and volume, shell thickness, weight and percentage of shell, hardness, breaking force, breaking energy, egg surface, farming conditions, type and species of birds, nutrition and geometric characteristics of eggs. Materials and Methods In this paper, initially in three phases, at 15 weeks, 19 weeks and 23 weeks, shell strength changes and physical properties of quail eggs on 90 quails during their first period of laying eggs were studied. Measured properties were included dimensions, weight, volume, specific gravity, shell thickness, weight and percentage of shell, breaking force, breaking energy, egg surface and some other properties. In the second part the effects of divergent selection for the bird’s body weight at four weeks of age on the quail eggs of fifth generation were studied. Measured properties were included dimensions, weight, volume, breaking force, breaking energy and some factors for direct and indirect measurement of strength of quail eggs. For direct measurement of the strength of eggshell of quail, two methods were employed: The first method was quasi-static compression test between two parallel plates of the universal testing machine and the second method was measuring specific gravity. In the first method, eggs were compressed between

    2001-04-01

    Japanese quail are small galliforms that are migratory and generally live 2 to 3years in the wild. Although there is evidence for other environmental cues, they primarily respond to long daylength for regulation of reproduction. In contrast to the Common Tern, a long-lived sea bird that shows little evidence of reproductive aging, Japanese quail follow a well-defined process of aging with evidence of declining function in reproductive, metabolic, and sensory systems. Our studies focus on neuroendocrine changes associated with reproductive aging in the Japanese quail, with emphasis on the male in order to study both endocrine and behavioral components of reproduction and the process of reproductive aging.

    2004-04-01

    This article describes the three stages of normal and pathological mourning, emphasizing the constellation embodied in Judaism for this process. These stages are: shock, acute mourning, working through and reconciliation. We present the important question: "How to define pathological mourning?" It is certainly not only a matter of extending beyond the accepted time limits of the mourning process, but also a question of the intensity of mourning in ones daily life, the degree of being preoccupied with it, and the degree of priority that this mourning process has in an individual's life. A number of forms of pathological mourning, during the three mentioned stages, are described, with special attention to Jewish mourning rituals, especially: The "rending of the garments" (Kriyah), the Kaddish, the Shiva, and the termination of mourning after a fixed period of time. One of the possible interpretations of these rituals is that they prevent and neutralize manifestations of aggression and violence. This is an analogue to the function of biological (genetic) rituals which according to the theory of Konrad Lorenz, also minimize the dangerous aggression between the species in nature. The religious ritual converts an aggressive behavior to a minimal and symbolic action, often re-directed, so that an originally dangerous behavior becomes a ritual with an important communicative function.

    2017-11-01

    The authors describe a spontaneous case of amyloid A (AA) amyloidosis in an adult female Japanese quail ( Coturnix japonica). The bird developed AA amyloidosis secondary to chronic peritonitis caused by a Gram-negative bacillus infection. Mild amyloid deposition was also identified in the intestinal tract of apparently healthy adult individuals, suggesting that quail may develop intestinal amyloidosis with age. Based on these observations, it was hypothesized that quail can develop AA amyloidosis following inflammatory stimulation with lipopolysaccharide (LPS). Therefore, adult quail were repeatedly injected with LPS and the development of AA amyloidosis was confirmed. The amyloid deposition in this model increased when quail amyloid was intravenously injected as an amyloid-enhancing factor. The experiments were repeated with young quail, but amyloid deposits were not observed following LPS injections. However, AA amyloidosis did develop when quail amyloid was injected in addition to LPS. These results indicated that adult quail develop AA amyloidosis after inflammatory stimulation with LPS. Furthermore, quail AA amyloidosis was shown to have transmissibility regardless of age. Interestingly, the authors found that administration of chicken amyloid fibrils also induced AA amyloidosis in young quail. This is the first report of cross-species transmission of avian AA amyloidosis.

    Left ventricular assist devices (LVADs) have progressively evolved, particularly in the last 10 years, to serve patients affected by severe heart failure as a bridge to transplant or destination therapy. The survival rate and quality of life of pre- and postimplant patients, as well as caregivers' perceptions and distress, are under investigation by the scientific community. But what caregivers think and feel after the loss of their loved one has not so far been examined. We contacted 16 principal caregivers of deceased LVAD patients by telephone. They were asked to evaluate their experience with LVADs and were administered a specific questionnaire about their mourning, the Caregiver Mourning Questionnaire (CMQ), to evaluate their perceptions of the physical, emotional, and social support-related problems that they had experienced during the previous 3 months. Positive aspects reported by the caregivers were the patient's overall subjective well-being and increased survival. Negative aspects were the difficulty to manage infections and the driveline, and the incomplete autonomy of the patient. Half of the caregivers reported not being preadvised about many of the problems they would face. The CMQ revealed that numerous caregivers had health problems, difficulty in sleeping, eating disorders, lack of energy, and loneliness. Use of psychotropic drugs and regrets about how they assisted their loved one also emerged. In conclusion, caregivers of LVAD patients may experience complicated mourning. Our data support in particular the need for an early intervention of palliative care which could prevent or reduce complicated mourning.

  12. Mourning, dreaming, and the discovery of the oedipus complex.

    Science.gov (United States)

    Mahon, Eugene J

    2013-10-01

    The author argues that the structure of mourning and the structure of the Oedipus complex are triadic, the latter being obvious and easy to conceptualize, while the former is quite subtle. When it is the father who is mourned, the son must repeatedly invoke the dead object so that libidinal cathexis can be reinvested in living objects. Such was the situation in which Freud found himself in 1896 when his father died--the triadic nature of the Oedipus complex ironically not yet discovered by him. In the author's belief, Freud's mourning and his attendant rich dream life occurring between 1896 and 1897 gave him access to the unconscious raw material that would eventually help him conceptualize the triadic structure at the instinctual core of the Oedipus complex. © 2013 The Psychoanalytic Quarterly, Inc.

    This experiment was conducted with Japanese quails at the poultry production farm (Poultry Research Unite, Nuclear Research Center, AEA, Inshas, Egypt) to determine the effects of stocking density on the growth, carcass composition, feed conversion, feed efficiency, corticosterone level, immune response and profit potential. A total of 924 Japanese quail chicks were brooded at 2 weeks of age in batteries at 44, 88 and 176 birds / m2 each of 3 replicates. Chicks brooded at 44 and 88 bird / m2 were grew significantly (P<0.05) during the experimental period more than those brooded at 176 bird/m2. Increasing birds density was associated with significant (P<0.05) increase in serum corticosterone level, carcass protein percent, live body weight per m2 and monetary returns. Carcass fat percent and immune response were reduced sharply with increasing quail stocking density. On the other hand, feed conversion was reduced, while feed efficiency was improved (P<0.05) by increasing quail stocking density

    Young Bobwhite quail (Colinus virginianus) were fed low and adequate protein purified diets with and without excess methionine to evaluate factors affecting methionine toxicity. Growth of quail fed an adequate protein (27%) diet, without supplemental glycine, was depressed by 1.75% and 2.25% excess methionine. Supplemental glycine (.3%) alleviated growth depression caused by 2.25% excess methionine. Quail fed 1.75% and 2.25% excess methionine developed signs of toxicity characterized by weakness, a lowered, outstretched neck when moving, and ataxia. In addition, quail would fall on their sides when disturbed and spin with their heads retracted. These conditions were transient in nature. Growth of quail fed a low protein (18.9%) diet was depressed by 1% and 1.5% excess methionine and DL-homocystine. Quail fed 1% and 1.5% excess methionine in this diet also developed signs of toxicity, the incidence of which was greater and the duration longer than occurred with quail fed adequate protein. Supplementing a low protein (20.15%) diet with .3% or .6% glycine or threonine or a combination of these amino acids did not alleviate growth depression caused by 1.5% excess methionine; however, 2% and 3% supplemental glycine were somewhat effective. Supplements of glycine (2%, 3%) and threonine (1%) completely reversed growth depression from 1% excess methionine but did not influence growth of controls, indicating that both amino acids counteract methionine toxicity. Both glycine and threonine alone improved growth by about the same extent in diets with 1% or 1.5% excess methionine; however, these amino acids alleviated less than 30% of the growth depression resulting from 1.5% excess methionine. The effectiveness of glycine in alleviating methionine toxicity in a low protein diet was decreased, and hemoglobin levels were depressed with 1.5% excess methionine compared to less amounts.

  19. New mourners, old mourners: online memorial culture as a chapter in the history of mourning

    2015-04-01

    How does online mourning differ from offline mourning? Throughout history, demographic, social and technological changes have altered mourners' social relationships with both the living and the dead, and hence their experiences of grief. Online technologies comprise the latest chapter in this story; earlier chapters include family/community mourning (pre-industrial), private mourning (twentieth century) and public mourning (turn of the millennium). Pervasive social media in which users generate their own content have significantly shifted mourners' social interactions and the norms that govern them, partly in new directions (such as enfranchising previously stigmatised griefs; more potential for conflict between mourners and others) but partly returning to something more like the relationships of the pre-industrial village (such as everyday awareness of mortality, greater use of religious imagery, more potential for conflict among mourners). Online, mourners can experience both greater freedom to be themselves and increased social pressure to conform to group norms as to who should be mourned and how.

  20. Materializing Mourning: Dickens, Funerals, and Epitaphs

    Full Text Available Dickens was fascinated with the material culture of the nineteenth century — with things, and the way in which they mediate feelings, relationships, and identities. While satirized as ‘Mr Popular Sentiment’ for some of his deathbed scenes, it is the material culture of mourning that most persistently engages his imagination. Alongside precious objects that attempt to bind the living and the dead in his fiction, we find other forms of commemoration which raise questions about the authenticity of the sentiments memorial objects are meant to express, questions that seem to have a particular urgency in the context of a rapidly developing commodity culture. This essay investigates some of the ways in which Dickens’s ambivalent attitude towards the material culture of mourning emerges in his writing.

    Full Text Available ABSTRACT Quail is an important and interesting group of galliform birds. The Common quail (Coturnix coturnix; the Japanese quail (Coturnix japonica; the Panda quail (Coturnix japonica; the Dotted white quail (Coturnix japonica and the Bobwhite quail (Colinus virginianus were used in this study. PCR-RFLP and SDS-proteins were performed to reveal the genetic characterization and genetic relationship of the studied quails. Analysis of fragments generated by digestion of PCR product with restriction enzyme NlaIII recorded highly polymorphic restriction profiles. There is a wide intraspecific COI, SEMA3E and TLX genes variability among the studied quails. Protein bands varied from10 to 18 between quails with minimum number of bands were in the Dotted white quail (10 bands and the maximum were in the Japanese quail (18 bands as measured by SDS-polyacrylamide gel electrophoresis. The Dotted white quail revealed the lowest similarity to the Bobwhite with a coefficient of 0.18 while The similarity coefficients between the Common quail and each one of the other quails were 0.67, 0.62, 0.45 and 0.42 for the Japanese, Panda, Dotted white and the Bobwhite quails, respectively. The results indicate that, PCR-RFLP and protein analyses are good techniques to evaluate genetic characterization and genetic relationship of these quails.

  2. The death of mourning: from Victorian crepe to the little black dress.

    Mourning is a natural response to loss. In the late eighteenth century and throughout the nineteenth century, in England and France, the bereaved was expected to follow a complex set of rules, particularly among the upper classes, with women more bound to adhere to these customs than men. Such customs involved wearing heavy, concealing, black costume and the use of black crepe veils. Special black caps and bonnets were worn with these ensembles. Widows were expected to wear these clothes up to four years after their loss to show their grief. Jewelry often made of dark black jet or the hair of the deceased was used. To remove the costume earlier was thought disrespectful to the deceased. Formal mourning culminated during the reign of Queen Victoria. Her prolonged grief over the death of her husband, Prince Albert, had much to do with the practice. During the succeeding Edwardian rule, the fashions began to be more functional and less restrictive, but the dress protocol for men and women, including that for the period of mourning, was still rigidly adhered to. When World War I began, many women joined the workforce. Most widows attempted to maintain the traditional conventions of mourning, but with an increase in the number of casualties, it became impractical for them to interrupt their work in order to observe the seclusion called for by formal mourning etiquette. Never had the code of mourning been less strictly applied than during this period. The mourning outfits of the time were modest and made of practical materials. Little jewelry and few other accessories were used. Certain aspects of traditional mourning were still followed, such as the use of jet beading, crepe trim, and widows' caps. However, the hemlines fell above the ankle, the veil was used to frame the face instead of cover it, and the v-neckline left the chest and neck bare. During the following decades, gradually the rules were relaxed further and it became acceptable for both sexes to dress in

    Full Text Available Toda vida humana está sometida a la experiencia múltiple y constante de la pérdida, por ello queda constituida como un sistema de duelos. Los efectos subjetivos que tales acontecimientos provocan pueden ser vividos en diversos registros. Con ocasión de un duelo, todo el sistema simbólico es llamado para trazar con él un borde al agujero provocado por una ausencia. Sin embargo, como constatamos de modo también reiterativo, las palabras desfallecen a la hora de nombrar lo que se lleva el muerto con su ausencia. ¿Cuál es pues el lugar de los escritos ante tales desfallecimientos? Después de plantear algunas consideraciones sobre las condiciones a un tiempo subjetivas y colectivas del duelo, propondré una conjetura sobre la articulación entre el duelo y la escritura. // Every human life is subject to a manifold and permanent experience of loss, and so ends up constituted by a system of mourning. The personal effect of such events may be faced in different ways. When coming up against a mourn, the whole symbolic system is called into action to enclose the void produced by absence. However, there is also a persistent collapse of words when attempting to name what is taken away by the dead person absence. So, what would be the role of writing against these afflictions? After putting forward some remarks on both subjective and social conditions of mourn, I will suggest a way by which writing and mourn may be bonded together.

  4. The characteristics and experiences of anticipatory mourning in caregivers of teenagers and young adults.

    This article reports a systematic review of literature undertaken to identify characteristics and experiences of anticipatory mourning in caregivers of teenagers and young adults with life-limiting or life-threatening conditions. A comprehensive literature search was conducted using the key words 'anticipatory', 'mourning', 'grief', and synonyms. This review focused on six studies that met inclusion criteria and reported characteristics of anticipatory mourning in caregivers of teenagers and young adults. Characteristics and experiences were sorted into four main themes: symptoms; a sense of loss; caregiver behaviour; and the unique experience of caring for, or losing, a teenager or young adult. The review suggests that there are characteristics and experiences of anticipatory mourning that are unique to caregivers of this age group. The review also suggests that consideration of anticipatory mourning is important in offering holistic care to young adults and their caregivers, and points to the need for further research in this area.

    Full Text Available Animals with socially monogamous mating systems are valuable for discovering proximate mechanisms of prosocial behavior and close social relationships. Especially powerful are comparisons between related species that differ in monogamous tendency. Birds are the most socially monogamous vertebrates. Thus far most research on mechanisms of pairing has used zebra finches, which do not have a relative with a different mating system, however. The goal of the experiments reported here was to develop a new comparative avian system by studying the pairing behavior of a reportedly strongly monogamous quail, the king quail (Coturnix chinensis, a species in the same clade as the less monogamous Japanese quail (Coturnix japonica, the subject of much prior research. In Experiment 1 male-female pairs of king quail housed together were initially avoidant or aggressive but most rapidly progressed to allopreening and huddling. A separation-reunion paradigm reliably elicited both of these behaviors in males that had cohabited for one week. In Experiment 2 the allopreening and huddling behavior of males in cohabiting pairs was highly selective, and a majority of the males were aggressive toward a familiar female that was not the cohabitation partner. In Experiment 3 males were separated from their female cohabitation partners for 9-10 weeks and then given two-choice tests. All but one male spent more time near an unfamiliar female, which may have reflected aggression and shows recognition of and memory for the past pairing experience. Thus king quail show robust, selective and easy to measure pairing behavior that can be reliably elicited with simple separation-reunion testing procedures. Copulation is rarely seen during tests. The behavior of king quail is a striking contrast to that of Japanese quail, providing a new comparative system for discovering mechanisms of behavior related to close social relationships and monogamy.

  10. Detection of Marek's disease virus DNA in Japanese quail susceptible to atherosclerosis

    Pyrzak, R.; Shih, J.C.H.

    1986-01-01

    Marek's disease virus (MDV) was demonstrated as an etiological agent which causes atherosclerosis in the chicken. Since herpes viruses are ubiquitous, incidences of viral atherogenesis in humans and other animals were speculated. In this laboratory, the atherosclerosis susceptible (SUS) and resistant (RES) Japanese quail were developed as the animal model for atherosclerosis research. The susceptibility of the animal might be due to an infection of MDV or a related quail herpes virus (QHV). An initial attempt to isolate viruses from quail and an agar gel precipitin test for MDC were not positive. A DNA hybridization technique was used to determine whether the MDC-DNA existed in the quail cell. The gene library of MDV EcoRl DNA fragments was used to prepare the DNA probe, labeled with [ 32 P] by nick translation. Dot hybridizations were carried out by mixing the MDV-DNA probe with DNAs isolated from quail tissues. A high stringent condition was used. From this experiment it was found that the tissues from the SUS quail were hybridization positive, but most of them from RES quail were negative. When aortas were compared, the severe atherosclerotic had a strong hybridization (3-4 cop. of genome/cell) whereas the others hybridized moderately (1 cop./cell). It was concluded that genes from MDV or a QHV indeed existed in Japanese quail

    Brachiocephalic arteries in quails are large arteries which are arising separately from the aortic arch. The aim of the present study was to determine the histomorphometric aspects of brachiocephalic arteries in the Japanese quail. The different layers of the brachiocephalic artery were studied quantitatively in 10, 20 and 60 days-old Japanese quail; (n = 6) and both sexes. Luminal diameter, thickness of the intima, media and adventitia, the percentage of the intima, media and adventitia, as compared with the total wall thickness were determined. It was found that luminal diameter and whole artery thickness increased by age (p < 0.05). In addition, the tunica media was the thickest layer, then tunica intima and at last tunica adventitia (p < 0.05). The muscularity of the right brachiocephalic artery was more than that of the left one (p < 0.05). Histomorphometric study of brachiocephalic arteries of Japanese quails showed that increasing of age causes increase of internal and external diameters of the artery and this increase in females was more than males.

    The pharmacokinetics of enrofloxacin and marbofloxacin was studied in Japanese quails and common pheasants. Healthy mature birds from both species and both genders were treated intravenously and orally with enrofloxacin (10 mg/kg) and marbofloxacin (5 mg/kg). After intravenous administration enrofloxacin was extensively metabolised to ciprofloxacin. Metabolites of marbofloxacin were not detected. Values of volume of distribution were respectively 4.63 l/kg and 3.67 l/kg for enrofloxacin and 1.56 l/kg and 1.43 l/kg for marbofloxacin. In quails, total body clearance values were higher than those in pheasants and other avian species. After oral application enrofloxacin was rapidly absorbed in quails, more rapidly than marbofloxacin. Pheasants absorbed both antimicrobials at a lower rate. Higher bioavailability was observed for marbofloxacin (118%). Relatively low bioavailability was established in quails for enrofloxacin (26.4%), accompanied by extensive conversion to ciprofloxacin. Generally, quails absorbed and eliminated both fluoroquinolones more rapidly than pheasants; the latter showed pharmacokinetics similar to poultry. Because of favourable pharmacokinetic properties, marbofloxacin should be preferred for oral administration in Japanese quails and pheasants for treatment of infections caused by equally susceptible pathogens.

    Previous observers, following Freud's formulations in Mourning and Melancholia, have disagreed over the question of whether the child can mourn. To support the thesis that the child does mourn but in a different way from the adult, the author focuses on the importance of the child's identification with the lost love object, the narcissistic regression, and the associated autoerotic activities. Clinical material is presented from the analysis of a latency child and of an adult, both of whom lost their mothers during childhood.

    Full Text Available An enteric syndrome observed in semi-intensively reared quails is described. The affected birds showed depression, severe diarrhoea and dehydration. The mortality occurred particularly in young birds. At necropsy, the prominent lesion was catarrhal enteritis. Laboratory investigations demonstrated the presence of coronavirus in the gut of dead animals. No additional pathogens were detected. To our knowledge, this is the first evidence for the presence of CoVs in quail with enteritis.

This research aimed at evaluating the live performance, egg quality, biometry of the reproductive system, and the gastrointestinal tract of Japanese quails (Coturnix coturnix japonica exposed to artificial light-emitting diodes (LED of different colors in comparison with fluorescent lamps. A total of 240 Japanese quails were distributed in completely randomized experimental design with four treatments (fluorescent lamp, and green, red, or blue LED lamps with six replicates of 10 birds each. Average egg weight and eggshell thickness were different (p0.05. The oviduct of 64-d-old hens exposed to green LED lighting was shorter (p<0.05 than those exposed to the fluorescent lamp. Red LED can be used to replace the fluorescent lamps, as they promote the same live performance, egg quality, and morphological development of the reproductive tract of laying Japanese quails.

    To explore the mourning process of people with dementia who have lost their spouse, using family caregivers' and professionals' perspectives and to devise grief care for people with dementia. There have been studies on the loss of one's spouse; however, little is known about widows and widowers with dementia as they may find it hard to tell their perception and feelings to others accurately because of cognitive impairment. Qualitative descriptive study using semi-structured interviews. Seven family caregivers and six professional caregivers from day care centres were interviewed between June and September 2015. Qualitative content analysis was used to identify mourning behaviours of people with dementia. In the mourning process of people with dementia, different behaviours were found according to dementia stages and different circumstances. In FAST2, they could remember their spouse's death. In FAST4 -6, it took 1 year to be able to perceive their spouse's death and more time to store it. In FAST 7, people with dementia did not discern his spouse's death throughout the process. Furthermore, it was revealed that people with dementia followed a different mourning process from conventional ones. In the care of widows and widowers with dementia it is crucial to adjust circumstances to allow people with dementia to guess reality. Further studies are needed to clarify differences between the mourning process of people with dementia and that of intact older people to develop a grief model and educational programmes. © 2017 John Wiley & Sons Ltd.

    2017-04-01

    Full Text Available Parasitic nematodes that infect quail have been understudied and long been dismissed as a problem in quail management. Within the Rolling Plains ecoregion of Texas, an area that has experienced quail population “boom and bust” cycles and ultimately a general decline, the need to determine why Northern bobwhite (Colinus virginianus populations are diminishing has increased in priority. Previously, caecal parasites have been documented to cause inactivity, weight loss, reduced growth, inflammation to the caecal mucosa, and even death. The caecal worm Aulonocephalus pennula is an intestinal nematode parasite that is commonly found within the caecum of quail, as well as many other avian species. In the Rolling Plains ecoregion, A. pennula has been documented to have as high as a 98% prevalence in bobwhite quail samples; however, the effect it has on its host is not well understood. The present study documents A. pennula causes no pathological changes within the caeca of the Northern bobwhite. However, there is concern for disruption of digestion and the possible implications of infection for wild bobwhite quail survival are discussed.

    1998-01-01

    We compared reproductive and physiological responses of captive female northern bobwhite (Colinus virginianus) and scaled quail (Callipepla squamata) under control and water deprivation conditions. Scaled quail required less food and water to reproduce successfully under control conditions than northern bobwhite. Additionally, in scaled quail, serum osmolality levels and kidney mass were unaffected by water deprivation, whereas in northern bobwhite, serum osmolality levels increased and kidney mass declined. This finding indicates that scaled quail may have osmoregulatory abilities superior to those of northern bobwhite. Under control conditions, northern bobwhite gained more body mass and produced more but smaller eggs than scaled quail. Under water deprivation conditions, northern bobwhite lost more body mass but had more laying hens with a higher rate of egg production than scaled quail. Our data suggest that northern bobwhite allocated more resources to reproduction than to body maintenance, while scaled quail apparently forego reproduction in favor of body maintenance during water deprivation conditions.

  19. Effect of chamomile extract on the welfare of laying Japanese quail

    Full Text Available ABSTRACT The objective of this study was to evaluate the effect of chamomile extract on Japanese quail on their performance, animal behavior, tonic immobility, body injuries, and surface temperature. The trial was conducted using 108 quail distributed in a completely randomized experimental design, with three treatments (0, 2.5, and 5.0 g chamomile/kg of feed, six replicates, and six birds per treatment, evaluated in six measures repeated in time (14, 28, 42, 56, 70, and 84 days of trial. The inclusion of chamomile presented a quadratic effect on sitting behavior, estimating the inclusion of 1.8 g chamomile/kg to maximize this behavior. There was a decreasing linear effect for aggressive pecking, that is, the higher the inclusion of chamomile in the diet, the lower the expression of this behavior. The inclusion of 1.8-5.0 g chamomile/kg in a Japanese quail diet reduces the behavior of aggressive pecking, in addition to keeping the birds seated longer. These results are innovative because they show in the literature for the first time that chamomile supplemented in Japanese quail diets has the capacity to modulate the behavior of the quail, leading to an improvement in the welfare of quail raised in cages.

    1974-01-01

    Four experiments were conducted to examine the riboflavin, niacin, pantothenic acid and choline requirements of young Bobwhite quail. Quail fed purified diets deficient in either riboflavin, niacin, pantothenic acid or choline grew poorly and high mortality occurred by 5 weeks of age. Under the conditions of these experiments, it was found that: (1) young quail require approximately 3.8 mg. riboflavin/kg. diet for satisfactory growth and survival; (2) no more than 31 mg. niacin/kg. diet are required for normal growth and survival of young quail; (3) the requirement for pantothenic acid is higher than has previously been reported, quail in these studies requiring 12.6 mg. pantothenic acid/kg. feed for growth and survival; and (4) the requirement for choline for reducing mortality is approximately 1000 mg./kg., while the amount necessary for normal growth of young quail is no greater than 1500 mg./kg. when the diet contains ample amounts of methionine. Quail fed a niacin-deficient diet developed stiff, shortened feathers and an erythema about the head; those receiving a riboflavin-deficient ration developed enlarged hocks and bowed legs, as did quail fed diets low or devoid of choline. Aside from slow growth, poor feathering was the only other indication that a deficient diet was being fed when quail were placed on a basal ration without pantothenic acid for five weeks.

  1. Characterization of Rous sarcoma virus-related sequences in the Japanese quail.

    1986-08-01

    We detected sequences related to the avian retrovirus Rous sarcoma virus within the genome of the Japanese quail, a species previously considered to be free of endogenous avian leukosis virus elements. Using low-stringency conditions of hybridization, we screened a quail genomic library for clones containing retrovirus-related information. Of five clones so selected, one, lambda Q48, contained sequence information related to the gag, pol, and env genes of Rous sarcoma virus arranged in a contiguous fashion and spanning a distance of approximately 5.8 kilobases. This organization is consistent with the presence of an endogenous retroviral element within the Japanese quail genome. Use of this element as a high-stringency probe on Southern blots of genomic digests of several quail DNA demonstrated hybridization to a series of high-molecular-weight bands. By slot hybridization to quail DNA with a cloned probe, it was deduced that there were approximately 300 copies per diploid cell. In addition, the quail element also hybridized at low stringency to the DNA of the White Leghorn chicken and at high stringency to the DNAs of several species of jungle fowl and both true and ruffed pheasants. Limited nucleotide sequencing analysis of lambda Q48 revealed homologies of 65, 52, and 46% compared with the sequence of Rous sarcoma virus strain Prague C for the endonuclease domain of pol, the pol-env junction, and the 3'-terminal region of env, respectively. Comparisons at the amino acid level were also significant, thus confirming the retrovirus relatedness of the cloned quail element.

    Quantitative security analysis evaluates and compares how effectively a system protects its secret data. We introduce QUAIL, the first tool able to perform an arbitrary-precision quantitative analysis of the security of a system depending on private information. QUAIL builds a Markov Chain model...... of the system’s behavior as observed by an attacker, and computes the correlation between the system’s observable output and the behavior depending on the private information, obtaining the expected amount of bits of the secret that the attacker will infer by observing the system. QUAIL is able to evaluate...... the safety of randomized protocols depending on secret data, allowing to verify a security protocol’s effectiveness. We experiment with a few examples and show that QUAIL’s security analysis is more accurate and revealing than results of other tools...

    Investigated were effects of gas mixture with up to 3.0 kgs/cm2 of krypton on the embryonic development of domesticated Japanese quail (Coturnix coturnix japonica dom.). Results demonstrated absence of a serious krypton effect on Japanese quail embryos. Development of embryos proceeded in due course; morphometrically the experimental embryos were essentially similar to controls. It should be noted that despite exposure to acute hypoxic hypoxia during the initial 12 hours of development in the krypton-containing gas mixture, viability of quail embryos was high enough which can be ascribed to the krypton protective action. Besides, an additional experiment showed that krypton partial pressure of 5-5.5 kgs/cm2 produces the narcotic effect on adult Japanese quails.

  6. Socially shared mourning: construction and consumption of collective memory

    2015-04-01

    Social media, such as YouTube, is increasingly a site of collective remembering where personal tributes to celebrity figures become sites of public mourning. YouTube, especially, is rife with celebrity commemorations. Examining fans' online mourning practices on YouTube, this paper examines video tributes dedicated to the late Steve Jobs, with a focus on collective remembering and collective construction of memory. Combining netnography with critical discourse analysis, the analysis focuses on the user comments where the past unfolds in interaction and meanings are negotiated and contested. The paper argues that celebrity death may, for avid fans, be a source of disenfranchised grief, a type of grief characterised by inadequate social support, usually arising from lack of empathy for the loss. The paper sheds light on the functions digital memorials have for mourning fans (and fandom) and argues that social media sites have come to function as spaces of negotiation, legitimisation and alleviation of disenfranchised grief. It is also suggested that when it comes to disenfranchised grief, and grief work generally, the concept of community be widened to include communities of weak ties, a typical form of communal belonging on social media.

    How might gay and lesbian literature be read not as a mimetic representation of homosexuality, but as an activity linked to problems of subjectivity and historiography? Reading Dale Peck's novel Martin and John alongside passages from Friedrich Nietzsche's "On the Uses and Disadvantages of History for Life" and Sigmund Freud's "Mourning and Melancholia," this essay argues for an understanding of Peck's text as an attempt to link two apparently different processes of import to contemporary gay male subjects in particular: the writing of what Nietzsche terms "critical history," and the mourning of those lost to HIV disease. It concludes by linking Martin and John to feminist critiques of identity and traditional historiography, as well as noting the connection between these two critiques.

    2002-03-01

    Full Text Available Abstract In line with the Gifu University's initiative to map the Japanese quail genome, a total of 100 Japanese quail microsatellite markers isolated in our laboratory were evaluated in a population of 20 unrelated quails randomly sampled from a colony of wild quail origin. Ninety-eight markers were polymorphic with an average of 3.7 alleles per locus and a mean heterozygosity of 0.423. To determine the utility of these markers for comparative genome mapping in Phasianidae, cross-species amplification of all the markers was tested with chicken and guinea fowl DNA. Amplification products similar in size to the orthologous loci in quail were observed in 42 loci in chicken and 20 loci in guinea fowl. Of the cross-reactive markers, 57.1% in chicken and 55.0% in guinea fowl were polymorphic when tested in 20 birds from their respective populations. Five of 15 markers that could cross-amplify Japanese quail, chicken, and guinea fowl DNA were polymorphic in all three species. Amplification of orthologous loci was confirmed by sequencing 10 loci each from chicken and guinea fowl and comparing with them the corresponding quail sequence. The microsatellite markers reported would serve as a useful resource base for genetic mapping in quail and comparative mapping in Phasianidae.

    2004-11-01

    Dove ovarian follicle is a complex structure composed of oocyte surrounded by a somatic compartment consisting of theca externa, theca interna and granulosa. The structure of ovarian follicle (1 and 2 mm) of dove was studied by electron microscopy. The granulosa was pseudostratified in the 1-mm-diameter follicles and stratified with two or three irregular rows of cells in the 2-mm-diameter follicles. In the larger follicle indentations between oocyte and granulosa cells become more numerous and the microvilli of granulosa cell elongated to form a zona radiata with similarly elongated oocyte microvilli. Lining bodies were present at the tips of granulosa microvilli and in the cortical region of the oocyte. In the oocyte cortex were observed coated pits, coated vesicles, dense tubules, multivesicular bodies and primordial yolk spheres. Primordial yolk spheres may contain lining bodies and were observed fused with dense tubules and multivesicular bodies or associated with smooth cisternae.

    2013-09-01

    The lack of preparation for dealing with death and the absence of the loved one may lead to organic and psychological reactions that, due to the adaptive capacity of the individual to the period of mourning, may result in interference in feeding habits and consequently on the person's nutritional status. This article addresses the effects of recent mourning on feeding behavior, followed by the analysis of the dietary interview from various standpoints. This includes the postmortem nutrition and feeding habits of the bereaved and the implications of this process on hunger, on thirst and on family cooking, with a focus on nutritional behavior and on the decisions that surround it. This is a review of the literature on the theme of death and mourning, which seeks to contextualize this theme around reflections based on this experience. It emphasizes the interaction of nutrition with the science of thanatology, which is an area still not properly examined and lacking study. The identification of this influence and its implications enables better planning of food strategies, contributing greatly to actions for coping and support during mourning.

    Full Text Available An experiment was conducted to study the effect of various probiotics on the performance of Japanese Quails. One hundred Japanese quail chicks were weighed individually and they were uniformly distributed equally to four dietary treatments consisting 25 birds in each. The starter and finisher diets were containing ME 2800 and 2600 Kcal/kg and protein 25 and 23 % respectively. The group T0(Controll fed standard quail diet and T1,T2 and T3 were fed probiotic Saccharomyces cerevisiae, Lactobacillus sporogenes and Saccharomyces boulardii @ 0.05 % in diet. The study was conducted for six weeks in the same managemental condition. Weekly live body weight and feed consumption were recorded. The group supplemented with Saccharomyces cerevisiae resulted in significantly higher growth rate and showed higher weight gain. The average feed efficiency and nitrogen retention were significantly higher in group supplemented with Saccharomyces cerevisiae. The cost of production /100gm of meat was found to be Rs.7.10, 6.84, 7.55 and 8.37 respectively in T0 to T3 groups. Thus, the study indicated that supplementation of Saccharomyces cerevisiae in the diet of Japanese quails was effective in improving performance of the quails. [Vet World 2009; 2(8.000: 321-322

  13. Stimulation of Egg Production in Japanese Quails by Enriching Feed with Residual Yeast

    2010-05-01

    Full Text Available Quail eggs are more and more approved for consumers because they bring many benefits to the human body. Therefore, quails breeding for eggs production have become a very profitable business. Residual yeast may be a nutritional supplement, especially rich in vitamins and proteins. This article studies the influence of residual beer yeast on egg laying in Japanese quails. In order to be integrated into the diet of quails the yeast has undergone a process of autolysis; its influence has been examined on separate groups. The results were reported as a percentage compared with the control group, where the feed does not contain this supplement. Due to its content rich in vitamins and proteins, the residual beer yeast used in feeding the quails bred for eggs stimulates egg laying.

  14. Between the imaginary and the real: photographic portraits of mourning and of melancholia in Argentina.

    Reineman, Julia

    2011-10-01

    During Argentina's 'Dirty War' (1976-83), the military regime attempted to erase an entire population; today the photographs of the dead/missing stand in defiance, contradicting that attempted erasure of the desaparecidos. In this essay, I explain the connection between photography and loss, and how photography fits within Lacan's understanding of the Imaginary, the Symbolic, the Real, and the 'gaze'. I discuss complicated mourning (circumstances which inhibit/delay mourning) and the difficulties created by political disappearances: as long as the family members maintain the belief that their loved one(s) might still be alive, they cannot begin the process of mourning the permanently lost object. Beginning with the Madres de Plaza de Mayo and, using the web-based art exhibits of Marcelo Brodsky and Inés Ulanovsky, I analyze the role of the photograph in Argentina, how it serves as a linking object, how it is used to symbolize the dead/missing, and how it can function to facilitate mourning, or to serve as proof of pathological melancholia. I argue that such artistic representations of loss function to reinscribe healthy mourning rituals within the Argentine society. Copyright © 2011 Institute of Psychoanalysis.

  16. Mourning, Memorials, and Religion: A Psychoanalytic Perspective on the Park51 Controversy

    Directory of Open Access Journals (Sweden)

    Nathan Carlin

    2011-06-01

    Full Text Available This article summarizes a version of the “mourning religion” thesis—derived from the work of Peter Homans and further developed and advanced by William Parsons, Diane Jonte-Pace, and Susan Henking—and then demonstrates how this thesis can shed light on the Park51 controversy. We argue that the Park51 controversy represents a case of incomplete cultural mourning of an aspect of American civil religion that manifests itself in melancholic rage by means of protests, threats to burn the Qur’an (as well as actual burnings of the Qur’an, and vandalism of mosques around the United States. We explore various losses—military, economic, and symbolic—and note that these losses remain ambiguous, therefore preventing closure and productive mourning. The fact that a permanent memorial still has not been built at Ground Zero reflects, and perhaps exacerbates, this incomplete cultural mourning. Also, the fact that Freedom Tower, the building to replace the Twin Towers, is to be 1776 feet tall reflects that the losses related to 9/11 are connected to American civil religion, as 1776 is a sacred year in American history. Setting aside the ethics and the politics related to this controversy, we attempt here to understand this controversy from a psychoanalytic perspective.

    Fertile Japanese quail eggs were exposed to continuous wave microwave radiation at an intensity of 5 mW/cm 2 (50 W/m 2 ) and a frequency of 2450 Mhz. The absorbed power density was determined to be 4.03 W/kg. The eggs were exposed throughout the first 12 days of the normal incubation period of 17.5 days. Non-exposed control eggs were incubated in a chamber identical to the exposure chamber. After hatching, exposed and control quail were reared in the conventional laboratory manner. Weekly body weight measurements were made to compare the growth patterns of exposed and control quail. The weights of the exposed male at the ages of 4 and 5 weeks were 12 and 7%, respectively, less than the control males. These differences approached statistical significance (P<=0.05). At 5 weeks of age the quail were challenged with sheep red blood cells (SRBC) and the levels of the anti-SRBC antibodies were determined. The levels of specific anti-SRBC antibodies, determined 4 days after antigen challenges, were of the same magnitude for both the exposed and control quail. Following this assessment of humoral immunity, the quail were sacrificed and the bursa of Fabricius and spleen were removed and a comparison was made of exposed and control birds. The weights of the bursa of Fabricius and spleen were not altered significantly by the microwave exposure. (author)

    To investigate the status, problems and prospects of Japanese quail (Coturnix coturnix japonica) farming in selected areas of Bangladesh. The study was conducted in 14 districts of Bangladesh, viz., Dhaka, Narayanganj, Munshiganj, Mymensingh, Netrakona, Faridpur, Jessore, Khulna, Satkhira, Kushtia, Bogra, Naogaon, Comilla, and Sylhet during the period from July 2011 to June 2012. A total of 52 quail farmers were interviewed for data collection using a structured questionnaire. Focus group discussions were also carried out with unsuccessful farmers and those want to start quail farming. Workers of quail farms, quail feeds and medicine suppliers, quail eggs and meat sellers were also interviewed regarding the issue. Out of 52 farms, 86.5% were operated by male, 67.3% farmers did not receive any training and 92.3% farmers had no earlier experience of quail farming although 58.0% farmers primary occupation was quail farming. Most of the farms (63.4%) were mixed in type having ≤5000 birds of two or three varieties. About 80.7% farms were operated separately round the year with no other poultry and 83.0% farmers wanted to expand their farming. The average pullet weight 145.0±0.12, 110.0±0.07, 120.0±0.22, and 128.0±0.17 g; age at the first lay 46.0±0.04, 42.0±0.31, 42.0±0.09, and 45.2±0.05 days; rearing period 15.0±0.01, 12.0±0.14, 15.0±0.32, and 15.2±0.18 months; culling period 15.5±0.14, 13.0±0.06, 15.0±0.03, and 15.4±0.26 months were for layer, parent stock, hatchery, and mixed farms, respectively. Most of the layer farms had an average egg production of ≤5000/day and net profit BDT 0.75/egg. However, an average number of birds, hatchability and net profit per day-old-chick were ≤5000, 76.8% and BDT 2.75, respectively, in the hatchery. Broiler quails were sold at 30 days with mean weight of 110.8 g and net profit BDT 9.02/bird. The major constraints of quail farming were higher feed price, outbreak of endemic diseases, lack of proper knowledge

  19. The dynamic interplay of mourning and forgiveness in the early development of the self and psychic structure.

    2014-04-01

    Mourning has received considerable attention in the psychoanalytic literature. Beginning with Freud's 1917 investigation, the central role of mourning in psychical development via identification has been articulated and subsequently elaborated upon by various authors (e.g., Klein, 1940; Schafer, 2005). Forgiveness, on the other hand, has until recently received considerably less attention, perhaps because of the strong religious and moral connotations often associated with it (Lansky, 2009a). Contemporary writers exploring the psychoanalytic implications of mourning and forgiveness, however, have suggested the importance of both in normal psychical development. The purpose of this paper is to propose an integrated model of mourning and forgiveness and explore its potential role in nascent infant development.

    A type of feather structure abnormality in Japanese quail resulting in shortened barbs on contour feathers was found to be controlled by a single autosomal recessive gene, sh (short barb). The mutation was first identified in a full-sib family from the University of British Columbia wild type line. Unlike other feather structure mutations in Japanese quail reported previously in literature, the short barb mutation is not associated with poor reproduction.

    Compared to the many studies on the physiological and toxicological effects of selenium (Se) in mammals, avian Se metabolism is still an unexplored topic. Some birds are useful as poultry for human nutrition. Moreover, birds belong to higher trophic levels in the biosphere and thus may play an important role in Se circulation in the ecosystem in the same way as mammals do. In this study, we analyzed the distribution and metabolism of Se in an experimental bird, the Japanese quail, which was fed drinking water containing sodium selenite or selenomethionine (SeMet). The highest concentration of Se was detected in the pancreas, followed by down feathers, liver, and kidneys. SeMet was more efficiently incorporated into the quail than selenite. The specific and preferable distribution of Se to the high molecular weight fraction in the serum of the quail was observed only in the SeMet-ingestion group. As in mammals, selenosugar and trimethylselenonium were the major metabolites in quail excreta. Three unknown Se metabolites were detected by HPLC-ICP-MS. Although part of the metabolic pathway of Se in the Japanese quail fed selenite and SeMet was the same as that observed in mammals, the bird also showed certain avian-specific metabolic process for Se.

  6. Quail FMO3 gene cloning, tissue expression profiling, polymorphism detection and association analysis with fishy taint in eggs.

    Directory of Open Access Journals (Sweden)

    Fengtao Mo

    Full Text Available Quail eggs comprise a significant and favourable part of table eggs in certain countries. Some quail eggs, however, present fishy off-flavor which directly influences their quality. It is reported that flavin-containing monooxygenase 3 (FMO3 is associated with fish-odour trait in human and animal products. FMO3 is responsible for the degradation of trimethylamine (TMA in vivo. Loss-of-function mutations in FMO3 gene can result in defective TMA N-oxygenation, giving rise to disorder known as "fish-odour syndrome" in human, as well as the fishy off-flavor in cow milk and chicken eggs. In order to reveal the genetic factor of fishy taint in quail eggs, we cloned the cDNA sequence of quail FMO3 gene, investigated FMO3 mRNA expression level in various tissues, detected SNPs in the coding region of the gene and conducted association analysis between a mutation and the TMA content in quail egg yolks. The 1888 bp cDNA sequence of quail FMO3 gene encoding 532 amino acids was obtained and characterized. The phylogenetic analysis revealed quail FMO3 had a closer relationship with chicken FMO3. The FMO3 mRNA was highly expressed in liver and kidney of quail. Nine SNPs were detected in the coding sequence of quail FMO3 gene, including a nonsense mutation (Q319X which was significantly associated with the elevated TMA content in quail egg yolks. Genotype TT at Q319X mutation loci was sensitive to choline. With addition of choline in the feed, the quails with homozygote TT at the Q319X mutation loci laid fish-odour eggs, indicating an interaction between genotype and diet. The results indicated that Q319X mutation was associated with the fishy off-flavor in quail eggs. Identification of the unfavorable allele T of quail FMO3 gene can be applied in future quail breeding to eliminate fishy off-flavor trait in quail eggs.

    Japanese Quail were exposed to a concentration of 300 to 350 ppm CO to maintain an equilibrium carboxyhemoglobin concentration of 30% for a period of 4 weeks. Compared to a control group of birds maintained in an identical chamber, the CO-exposed quail demonstrated increases in hematocrit ratio and hemoglobin concentration. At the end of the exposure period, the CO-exposed quail had significantly larger plasma glucose concentrations than the control birds. Cardiac and skeletal muscle carbohydrate stores were not affected by chronic CO exposure.

    Qualified food composition data on lipids composition are needed to evaluate intakes as a risk factor in the development of heart disease. Proximal composition, cholesterol and fatty acid content of chicken and quail eggs, usually consumed or traded, were analysed. Proximal composition were determined using AOAC (1984) specific techniques; lipids were extracted by a Folch's modified technique and cholesterol and fatty acids were determined by gas chromatography. Results corroborate the stability of eggs composition. Cholesterol content of quail eggs is similar to chicken eggs, but it is almost the half content of data registered in Handbook 8. Differences may be attributed to the analytical methodology used to obtain them. This study provides data obtained with up-date analytical techniques and accessory information useful for food composition tables.

    Full Text Available Fumarolic Ice caves on Antarctica’s Mt. Erebus contain a dark oligotrophic volcanic ecosystem (DOVE and represent a deep biosphere habitat that can provide insight into microbial communities that utilize energy sources other than photosynthesis. The community assembly and role of fungi in these environments remains largely unknown. However, these habitats could be relatively easily contaminated during human visits. Sixty-one species of fungi were identified from soil clone libraries originating from Warren Cave, a DOVE on Mt. Erebus. The species diversity was greater than has been found in the nearby McMurdo Dry Valleys oligotrophic soil. A relatively large proportion of the clones represented Malassezia species (37% of Basidomycota identified. These fungi are associated with skin surfaces of animals and require high lipid content for growth, indicating that contamination may have occurred through the few and episodic human visits in this particular cave. These findings highlight the importance of fungi to DOVE environments as well as their potential use for identifying contamination by humans. The latter offers compelling evidence suggesting more strict management of these valuable research areas.

    Northern bobwhite (Colinus virginianus) and Scaled quail (Callipepla squamata) have been declining steadily throughout much of their historical range over the past few decades. Even the Rolling Plains of Texas, historically rich with wild quail and one of the last remaining quail strongholds, has been suffering a population decline, most notably since 2010. Gambel's quail (Callipepla gambelii) have also been experiencing their own decline throughout their respective range, but not as significant as that of other species of quail. Eyeworms (Oxyspirura petrowi) in quail have been recognized for years but not thoroughly studied until recently. New research reveals that O. petrowi infection can cause inflammation, oedema, and cellular damage to the eye of the quail host. The objective of this research was to better understand the prevalence of the eyeworm infection in different quail species, expand on known distribution, and determine if there is a relationship between location and species infected with eyeworms. Northern bobwhite, Scaled quail and Gambel's quail were hunter-donated from one county within Texas, New Mexico and Arizona, and examined for the prevalence, mean abundance and mean intensity of eyeworm infection from November 2013 to February 2014. Quail from every location were found to have individuals with a varying degree of eyeworm infection. This is the first study to document eyeworm infection in Gambel's quail and in quail in New Mexico and Arizona, and reports the highest eyeworm infection found in Northern bobwhite and Scaled quail.

    Full Text Available TYR (Tyrosinase and TYRP1 (Tyrosinase-related protein 1 play crucial roles in determining the coat color of birds. In this paper, we aimed to characterize the relationship of TYR and TYRP1 genes with plumage colors in Korean quails. The SNPs were searched by cDNA sequencing and PCR-SSCP in three plumage color Korean quails (maroon, white and black plumage. Two SNPs (367T→C and 1153C→T were found in the coding region of TYRP1 gene, but had no significant association with plumage phenotype in Korean quails. The expression of TYR was higher in black plumage quails than that in maroon plumage quails. In contrast, the expression of TYRP1 was lower in black plumage quails than that in maroon plumage quails. This study suggested that the melanic plumage color in Korean quails may be associated with either increased production of TYR or decreased production of TYRP1.

    Coturnix chinensis (blue-breasted quail) has been classically grouped in Galliformes Phasianidae Coturnix, based on morphologic features and biochemical evidence. Since the blue-breasted quail has the smallest body size among the species of Galliformes, in addition to a short generation time and an excellent reproductive performance, it is a possible model fowl for breeding and physiological studies of the Coturnix japonica (Japanese quail) and Gallus gallus domesticus (chicken), which are classified in the same family as blue-breasted quail. However, since its phylogenetic position in the family Phasianidae has not been determined conclusively, the sequence of the entire blue-breasted quail mitochondria (mt) genome was obtained to provide genetic information for phylogenetic analysis in the present study. The blue-breasted quail mtDNA was found to be a circular DNA of 16,687 base pairs (bp) with the same genomic structure as the mtDNAs of Japanese quail and chicken, though it is smaller than Japanese quail and chicken mtDNAs by 10 bp and 88 bp, respectively. The sequence identity of all mitochondrial genes, including those for 12S and 16S ribosomal RNAs, between blue-breasted quail and Japanese quail ranged from 84.5% to 93.5%; between blue-breasted quail and chicken, sequence identity ranged from 78.0% to 89.6%. In order to obtain information on the phylogenetic position of blue-breasted quail in Galliformes Phasianidae, the 2,184 bp sequence comprising NADH dehydrogenase subunit 2 and cytochrome b genes available for eight species in Galliformes [Japanese quail, chicken, Gallus varius (green junglefowl), Bambusicola thoracica (Chinese bamboo partridge), Pavo cristatus (Indian peafowl), Perdix perdix (gray partridge), Phasianus colchicus (ring-neck pheasant), and Tympanchus phasianellus (sharp-tailed grouse)] together with that of Aythya americana (redhead) were examined using a maximum likelihood (ML) method.

    Experiments were conducted with young Bobwhite quail (Colinus virginianus) to investigate the effect of differing dietary protein levels and nondetrimental amounts of excess methionine on choline needs. Growth and feed consumption of quail fed an adequate (27.3%) protein purified diet supplemented with 2000 mg/kg of choline were unaffected by increasing the level of excess methionine to 1.75%; however, greater amounts (2.0%, 2.25%) of excess methionine depressed growth (P less than .01), reduced feed consumption (P less than .01), and decreased feed utilization (P less than .05). Quail fed a purified diet containing 13.85% protein and 515 mg/kg of choline grew poorly. Growth was unaffected by additional choline in this diet. Growth was suboptimal among quail fed purified diets containing adequate or high (41.55%) levels of protein in which choline was limiting; however, a high level of protein did not in itself affect performance. Growth was improved by supplemental choline in these diets. Growth of quail fed purified diets with up to 1.35% excess methionine which were limiting (531 mg/kg) in choline was less than that of groups fed 2000 mg/kg of added dietary choline (P less than .01); however, excess methionine did not significantly influence growth of quail fed choline-deficient diets. These experiments indicate that neither high dietary protein nor excess methionine, fed at non-growth-depressing levels, increases dietary choline needs for young Bobwhite quail.

  16. Presence, Mourning, and Beauty: Elements of Analytic Process.

    Markman, Henry C

    2017-12-01

    Analyst and patient occasionally arrive at moments of heightened meaning and aliveness. These moments can be transformative and lead to psychic change in the patient. They give life and arouse hope, and feel "real" in a new way, though often entailing emotional turbulence. Specific internal work must be done by the analyst to allow for and foster these experiences. This involves a kind of mourning process in the analyst that allows for "presence" and "availability" as described by Gabriel Marcel, and for the "at-one-ment" described by Bion. These transforming moments can be viewed in an aesthetic realm, along the lines of Keats's "Beauty is truth, truth beauty." This embodies the analytic value of emotional truth. These moments are shared and their emergence is an intersubjective creation. Clinical illustrations show how the internal work of mourning by the analyst through directed introspection allows for presence and availability, and then for shared moments of beauty with the patient.

  17. Entextualising mourning on Facebook: stories of grief as acts of sharing

    2015-04-01

    Web 2.0 mourning is said to afford increased opportunities for the deceased's and mourners' visibility as well as create in the bereaved an increased sense of social support through the participatory entextualisation of mourning. So far, however, there has been little systematic attention to the uses of narrative in social network sites. The present article addresses this gap by providing an analysis of entextualised moments of mourning as stories shared by a single author over a six-month period on a Facebook Rest in Peace memorial group. The article foregrounds heterogeneity in narrative activity across posts, linking diversity in ways of telling to different types of the online mourner's positioning at three interrelated levels of discourse construction: (1) the representation of the event of death, (2) the alignment (or disalignment) with the dead and the networked mourners and (3) the poster's self. It is argued that telling stories on Facebook memorial sites constitutes an act of sharing affording networked individuals resources for making meaning out of the meaninglessness of a loved one's death in ways that can help render the painful experience of loss tellable and also create a sense of ambient affiliation or affinity with networked mourners.

    Full Text Available The objective of this study was to evaluate the potassium requirement for laying Japanese quails. Two hundred and forty quails were distributed in a randomized block design, with five treatments and six replicates, with eight birds each. The treatments consisted of a basal diet deficient in potassium (K (2.50 g/kg, supplemented with potassium carbonate, to replace the inert, to reach levels of 2.50, 3.50, 4.50, 5.50 and 6.50 (g/kg of K in the diet. There was a quadratic effect of K levels on feed intake, egg production, egg mass and feed conversion per egg mass and per egg dozen, estimating the requirements of 4.26, 4.41, 4.38, 4.43 and 4.48 (g/kg of K diet, respectively. There was no significant effect on the levels of K in the diet on egg weight, albumen weight, percentage of yolk or shell and yolk color. However, yolk and shell weights reduced and the albumen percentage increased linearly with increasing levels of K in the diet. Despite the reduction of shell weight, the increased levels of K did not influence the specific gravity and shell thickness. The use of 4.41 g/kg of potassium is recommended in the diet for laying Japanese quails.

    1982-01-01

    A study was conducted to examine the protein requirement of young endangered masked Bobwhite quail (Colinus virginianus ridgwayi). Five practical starting rations containing 24 to 32% protein were fed alone and supplemented with methionine for 5 weeks. Supplemental methionine significantly improved growth of quail fed diets containing 24 and 26% protein. Increasing the protein level improved growth of quail fed unsupplemented diets but did not do so when diets contained supplemental methionine. A methionine-supplemented ration containing 24% protein appeared adequate for supporting rapid growth of masked Bobwhite quail.

  1. Genetic evaluation of European quails by random regression models

    2012-09-01

    Full Text Available The objective of this study was to compare different random regression models, defined from different classes of heterogeneity of variance combined with different Legendre polynomial orders for the estimate of (covariance of quails. The data came from 28,076 observations of 4,507 female meat quails of the LF1 lineage. Quail body weights were determined at birth and 1, 14, 21, 28, 35 and 42 days of age. Six different classes of residual variance were fitted to Legendre polynomial functions (orders ranging from 2 to 6 to determine which model had the best fit to describe the (covariance structures as a function of time. According to the evaluated criteria (AIC, BIC and LRT, the model with six classes of residual variances and of sixth-order Legendre polynomial was the best fit. The estimated additive genetic variance increased from birth to 28 days of age, and dropped slightly from 35 to 42 days. The heritability estimates decreased along the growth curve and changed from 0.51 (1 day to 0.16 (42 days. Animal genetic and permanent environmental correlation estimates between weights and age classes were always high and positive, except for birth weight. The sixth order Legendre polynomial, along with the residual variance divided into six classes was the best fit for the growth rate curve of meat quails; therefore, they should be considered for breeding evaluation processes by random regression models.

    This experiment investigated the effect of betaine supplementation to low methionine diet on egg quality of quails. A total of 340 laying quails (Coturnix coturnix japonica) was divided into 4 dietary treatments with 5 replicates of 17 quails each. The experiment was assigned in a completely randomized design. The four dietary treatments were the low methionine diet (0.3% methionine) without betaine supplementation and the low methionine diet supplemented with 0.07, 0.14, and 0.21% betaine. The experimental diets were applied for 8 weeks and the egg quality traits were measured at the age of 16 and 20 weeks. The data were subjected to analysis of variance, and when the treatment indicated significant effect, it was continued to orthogonal polynomial test to determine the optimum level of betaine. Increasing dietary levels of betaine increased the fat content of the egg with the linear regression of y = 11.0949 + 4.1914x (R2 = 0.18). However, supplementation of betaine did not affect protein content, yolk, albumen, and eggshell percentage. It can be concluded that betaine supplementation up to 0.21% to low methionine diet only had little effect in improving the quality traits of quail eggs.

    Trenbolone acetate is a synthetic androgen that is currently used as a growth promoter in many meat-exporting countries. Despite industry laboratories classifying trenbolone as nonteratogenic, data showed that embryonic exposure to this androgenic chemical altered development of the immune system in Japanese quail. Trenbolone is lipophilic, persistent, and released into the environment in manure used as soil fertilizer. This is the first study to date to assess this chemical's immunotoxic effects in an avian species. A one-time injection of trenbolone into yolks was administered to mimic maternal deposition, and subsequent effects on the development and function of the immune system were determined in chicks and adults. Development of the bursa of Fabricius, an organ responsible for development of the humoral arm of the immune system, was disrupted, as indicated by lower masse, and smaller and fewer follicles at day 1 of hatch. Morphological differences in the bursas persisted in adults, although no differences in either two measures of immune function were observed. Total numbers of circulating leukocytes were reduced and heterophil-lymphocyte ratios were elevated in chicks but not adults. This study shows that trenbolone acetate is teratogenic and immunotoxic in Japanese quail, and provides evidence that the quail immune system may be fairly resilient to embryonic endocrine-disrupting chemical-induced alterations following no further exposure posthatch.

    This study proposes through a case illustration that psychoanalytic patients who can process both aggression and loss through a mourning process are able to free themselves from pathological self attack when the object relations work of attachment, psychic holding, and separation transpires. In the case of Helen discussed here, transformation through a "developmental mourning process" results in the evolution of powerful psychological capacities for interiority, self agency, and interpersonal compassion. This developmental mourning process is endowed with the assimilation and psychic fantasy symbolization of aggression.

    To compare the histological, morphological and the biophysical measurements between hen and quail corneas, in order to determine which of them were better suited for use as an animal model for research into corneal refractive surgery. A study was performed using the biophysical measurements of the cornea (curvature, thickness, refraction, and axial length) of 20 animals (10 hens and 10 quails). The corneas were then prepared for histological analysis under microscopy light. The analysis showed that both groups have the same number of corneal layers as the human cornea and with an evident Bowman's layer. The thickness of the hen cornea and axial length of the eye, 225.3±18.4μm and 12.8±0.25mm, respectively, were larger than that of the quail (Phen central cornea, 3.65±0.08mm, was greater than that for the quail (Ppower of each cornea was similar.

    The present study was carried out at the poultry farm found in the Nuclear Research Center, Atomic Energy Authority, Inshas, Sharkia Governorate, Egypt, during January 2009. A total number of two hundreds and seventy five quail eggs were used in an experiment of a completely randomized design to estimate hatchability percentage, chick weight at hatch, growth performance, some blood parameters and carcass traits of Japanese quails as affected by injecting their eggs with pyridoxine. Eggs were divided into 5 groups (55 eggs each); the first group (without injection) was served as control while the second group was injected in the width end of the egg with 500 μl saline. The third, fourth and fifth groups were injected in the width end of the Japanese quail eggs with 40, 80 and 120 μg pyridoxine, respectively, dissolved in 500 μl saline. Hatchability percentage, live body weight, daily body weight gain and some organ weights (liver, gizzard and heart) were studied. At the end of the experiment, blood samples were collected for analyses. It was observed that the groups of quail eggs received 120 μg pyridoxine injection recorded the highest hatchability percent. Chick weight at hatch was non-significantly affected by saline solution injection. The birds hatched from the groups of quail eggs received 120μg pyridoxine recorded the highest live body weight, especially during the 2 nd and 3 rd weeks of age. The daily body weight gain was significantly affected by pyridoxine injection only during the intervals of 1 to 2, 3 to 4 and from 1 to 6 weeks of age. Serum total protein, albumin and globulin concentrations were highly significantly elevated in the birds hatched from the groups of quail eggs received 120μg pyridoxine than other groups. Serum AST activity was highly significantly increased in the birds hatched from the groups of quail eggs received 40 μg pyridoxine than other groups while serum ALT activity and calcium concentration were non

    European quail (Coturnix c. coturnix) may share with Japanese quail (Coturnix c. japonica) its potential as an intermediate host and reservoir of avian influenza viruses (AIV). To elucidate this question, European quail were experimentally challenged with two highly pathogenic AIV (HPAIV) (H7N1/HP and H5N1/HP) and one low pathogenic AIV (LPAIV) (H7N2/LP). Contact animals were also used to assess the viral transmission among birds. Severe neurological signs and mortality rates of 67% (H7N1/HP) and 92% (H5N1/HP) were observed. Although histopathological findings were present in both HPAIV-infected groups, H5N1/HP-quail displayed a broader viral antigen distribution and extent of microscopic lesions. Neither clinical nor pathological involvement was observed in LPAIV-infected quail. Consistent long-term viral shedding and effective transmission to naive quail was demonstrated for the three studied AIV. Drinking water arose as a possible transmission route and feathers as a potential origin of HPAIV dissemination. The present study demonstrates that European quail may play a major role in AI epidemiology, highlighting the need to further understand its putative role as an intermediate host for avian/mammalian reassortant viruses.

    Full Text Available Background: Quail eggs as a food item have recently been introduced into the diet of some Cameroonians. These eggs are being sold in local markets, but with many unfounded health claims. One claim is that quail eggs can reduce blood glucose levels in diabetics. It was therefore necessary to evaluate the effect of consuming quail eggs on blood glucose levels, lipid profiles, and oxidative stress parameters in diabetes-induced rats. Methods: Twenty Wistar rats weighing, on average, 250 g were divided into four groups of five rats each. Group 1 consisted of rats with normal blood glucose, and the other three groups (2, 3, and 4 consisted of diabetes-induced rats achieved by intravenous injection of streptozotocin. During 16 days, rats in groups 1 and 2 received distilled water; and rats in groups 3 and 4 received quail and chicken eggs, respectively, with gastroesophageal probe at a dose of 1 mL/200 g body weight. Fasting blood glucose levels were determined in all the groups on the 1st, 7th, 14th, and 17th days after induction of diabetes. On the 17th day, the fasting rats were sacrificed, and blood and liver samples were collected for biochemical analyses. Results: In 17 days, the consumption of quail and chicken eggs had no effect on blood glucose levels of diabetic rats. Total cholesterol levels were higher in groups 3 (75.59 mg/dL and 4 (59.41 mg/dL compared to group 2 (55.67 mg/dl, although these differences were not significant (all p>0.05. Triglyceride levels were significantly higher (p <0.05 in groups 3 (106.52 mg/dL and 4 (109.65 mg/dL compared to group 2 (65.82 mg/dL. Quail eggs had no effect on oxidative stress parameters (malondialdehyde, hydroperoxides, and catalase. Conclusions: The consumption of quail eggs by diabetic rats at the tested dose had no effect on blood glucose level and oxidative stress parameters and may have a negative effect on lipid profile.

    Perinatal intimate partner violence (IPV) is common and has significant negative health outcomes for mothers and infants. This study evaluated the effectiveness of an IPV intervention in reducing violence among abused women in perinatal home visiting programs. This assessor-blinded multisite randomized control trial of 239 women experiencing perinatal IPV was conducted from 2006 to 2012 in U.S. urban and rural settings. The Domestic Violence Enhanced Home Visitation Program (DOVE) intervention group (n = 124) received a structured abuse assessment and six home visitor-delivered empowerment sessions integrated into home visits. All participants were screened for IPV and referred appropriately. IPV was measured by the Conflicts Tactics Scale2 at baseline through 24 months postpartum. There was a significant decrease in IPV over time (F = 114.23; p < 0.001) from baseline to 1, 3, 6, 12, 18, and 24 months postpartum (all p < 0.001). Additional models examining change in IPV from baseline indicated a significant treatment effect (F = 6.45; p < 0.01). Women in the DOVE treatment group reported a larger mean decrease in IPV scores from baseline compared to women in the usual care group (mean decline 40.82 vs. 35.87). All models accounted for age and maternal depression as covariates. The DOVE intervention was effective in decreasing IPV and is brief, thereby facilitating its incorporation within well-woman and well-child care visits, as well as home visiting programs, while satisfying recommendations set forth in the Affordable Care Act for IPV screening and brief counseling.

    Full Text Available The world united in unprecedented ways in mourning the global icon Nelson Mandela, an emotionally charged historical event in which digital visuality played an influential role. The memorial service for Nelson Mandela on Tuesday, 10 December 2013, gathered dignitaries and celebrities from around the world at the First National Bank Stadium in Johannesburg, to mourn the passing of Madiba and to celebrate his life work. At the Grand Parade in Cape Town, the event was broadcast on large public screens, followed by live music performances and narrowcast interaction with the audience. Building on recent research on public screens during global media events, this article addresses the mediated mourning rituals at the Grand Parade in terms of a sacred drama. Focusing on social relationality, the article discusses how digital visuality mediated a sense of global communitas, thus momentarily overcoming historical frictions between the global north and the global south, while expanding the fame of Madiba. Paying attention to the public display of visual memory objects and the emotional agency of images, it argues that digital visuality mediated social frictions between the living and the dead, while recasting a historical subject as a historical object. The article further discusses how digital visuality mediated cultural frictions of apartheid and xenophobia, through the positioning of Mandela in the pantheon of Pan-African icons, thus underlining the African origin of this global icon. The analysis is based on ethnographic observations and experiences in Cape Town.

    2017-04-03

    Much has been written on the successful lesbian, gay, bisexual, transgender, and intersex movement in South Africa, and the resulting institutionalization of sexual minority rights. Comparatively less has been written about the forms of activism undertaken specifically by Black lesbians that are not oriented toward legal change. In this article, I assert the need to examine public demonstrations of mourning as an act of Black lesbian resistance to violence in South Africa. Based on in-depth interviews with members of Free Gender, a Black lesbian organization, I argue that members' conceptualizations of mourning as providing community support force a reconsideration of what it means to be human. In order to grasp the decolonial potential of Free Gender's activism, I draw on Sylvia Wynter's argument that a singular Western bourgeois conception of human has come to dominate globally.

    Full Text Available Katuk (Sauropus androgynus L Merr is known to contain carotenoids, vitamin E, vitamin C, protein, and sterol compounds. This study was aimed to determine whether phytosterol in Sauropus androgynus (SA leaf affected the reproductive system of female quails. One hundred and fifty female quails were raised from 2-27 weeks old and divided into three dietary treatment, with five replicates and 10 quails in each replicate. The treatment diets were: 1 control group: diet without katuk leaf meal; 2 diet with 9% SA ethanol extract (TEK; 3 Diet containing 9% SA meal (TDK. The TDK-fed quails laid their first eggs at 46 day of age, compared with the TEK (52 day and the control groups (53 day. The highest fertility (94.55% and hatchability (93.29% were obtained from the TDK fed quails at the age of 23 and 24 weeks, respectively. These findings indicated that the reproductive system of female quails were improved not only by phytosterol in SA leaf, but also by the β-carotene, vitamin C, α-tocopherol in SA leaf.

    Full Text Available The identification of migration routes, wintering grounds and stopover sites are crucial issues for the understanding of the Palearctic-African bird migration system as well as for the development of relevant conservation strategies for trans-Saharan migrants. Using miniaturized light-level geolocators we report a comprehensive and detailed year round track of a granivorous trans-Saharan migrant, the European Turtle Dove (Streptopelia turtur. From five recovered loggers, our data provide new insights on migratory journeys and winter destinations of Turtle Doves originating from a breeding population in Western France. Data confirm that Turtle Doves wintered in West Africa. The main wintering area encompassed Western Mali, the Inner Delta Niger and the Malian/Mauritanian border. Some individuals also extended their wintering ranges over North Guinea, North-West of Burkina Faso and the Ivory-Coast. Our results reveal that all individuals did not spend the winter period at a single location; some of them experienced a clear eastward shift of several hundred kilometres. We also found evidence for a loop migration pattern, with a post-breeding migration flyway lying west of the spring route. Finally, we found that on their way back to breeding grounds Turtle Doves needed to refuel after crossing the Sahara desert. Contrary to previous suggestions, our data reveal that birds used stopover sites for several weeks, presumably in Morocco and North Algeria. This later finding is a crucial issue for future conservation strategies because environmental conditions on these staging areas might play a pivotal role in population dynamics of this declining species.

    Four experiments were conducted with purified diets to examine the influence of protein level and to estimate the sulfur amino acid (S.A.A.) requirement of young Bobwhite quail (Colinus virginianus). These studies demonstrated (I) that 26% protein was sufficient for rapid growth when the diet was supplemented with methionine; (2) that diets containing higher levels of protein (29.3% and 31.3%) failed to support satisfactory growth unless they contained supplemental methionine; and (3) that young Bobwhite quail require no more than 1.0% sulfur-containing amino acids for optimal growth and efficiency of feed utilization. A fifth experiment was conducted to examine the protein and S.A.A. requirements of young Bobwhite quail using practical rations and to compare results with those obtained with purified diets. Diets containing 24%, 26% and 28% protein were supplied with and without supplemental methionine in a five week study. Results showed significant growth responses to protein and supplemental methionine. Responses showed that Bobwhite quail require no more than 26% protein for maximum growth and efficiency of feed utilization when the S.A.A. level of the diet was approximately 1.0%. The results were in close agreement with those obtained with purified diets. These findings define more precisely than had been known the quantitative requirements of young Bobwhite quail for protein and for the S.A.A. necessary for optimal growth.

    Full Text Available The objective of this study was to estimate the nutrient requirements of digestible threonine for meat-type quails (Coturnix coturnix sp in the growth phase. A total of 1350 not sexed meat-type quails were distributed in a completely randomized design with six threonine levels (10.80, 11.50, 12.20, 12.90, 13.60 and 14.30 g/kg as fed, five replications and 45 quails per experimental unit, from 1 to 14 days of age. The threonine levels in the diet had a quadratic effect on body weight, feed intake and weight gain. Estimates for highest body weight (79.41 g, feed intake (128.96 g/bird and weight gain (70.73 g were observed with diets containing 12.60 g/kg of digestible threonine. According to the LRP model, the threonine intake was estimated at 13.40 g/kg of digestible threonine. Protein deposition rate and energy retained in the carcass showed quadratic effect, with estimated digestible threonine levels of 11.80 and 12.00 g/kg in the diet for maximum protein deposition rate (2.00 g/bird and retained energy in the carcass (15.88 kcal/g, respectively. There was a linear effect on feed cost per kg of live weight gain as threonine levels were increased. Nutritional requirement of digestible threonine for meat-type quails for maximum growth is 12.60 g/kg, corresponding to a digestible threonine:digestible lysine ratio of 67.02.

    Full Text Available Aim: Genotype VII Newcastle disease virus (NDV is the most predominant NDV strains that circulating in Malaysia; thus, this study was aimed to determine the susceptibility of Japanese quails toward genotype VII NDV. Clinical signs, gross pathological lesions of organs, positive detection of virus in organs and cloacal swabs, as well as the expression of the antibody titer, were used as parameters to assess the susceptibility of Japanese quails following infection of genotype VII NDV. Materials and Methods: About 20 quails were divided into three groups (n=8 for Groups A and B; n=4 for the control group. The quails in the Groups A and B were infected via intraocular route with 0.03 ml of 103.5 ELD50 and 107.0 ELD50 of NDV strain IBS 002, respectively, while the control group received 1x phosphate-buffered saline. Cloacal swabs and necropsy were taken on day 7 post-infection for all quails were subjected to one-step reverse transcription real-time quantitative polymerase chain reaction (RT-qPCR for detection of virus and examination for gross pathological lesion, respectively. Blood serums of infected quails were taken on day 10, 14, and 21 post-day infections and were subjected for hemagglutination inhibition (HI assay. Results: Depression and ruffled feathers, trachea rales, leg paralysis, and torticollis were shown in some of the quails in both infected groups. Based on statistical analysis, there was no significant difference (p>0.05 in clinical signs between the infected groups. The results for RT-qPCR were found to be negative for all groups, and no gross pathological lesions of organs observed for quails in both infected groups. Trachea, proventriculus, and cecal tonsil were taken for the detection of NDV by RT-qPCR, and some of the organ samples showed positive detection of virus in both infected groups. HI assay showed an increase in mean titers of antibody across time and between infected groups. Conclusion: In summary, Japanese quails

    Eurasian collared doves (Streptopelia decaocto) are thought to originate from India and they have colonized, throughout the centuries, the Middle East and, more recently, Mediterranean countries such as Italy and Spain. In the present paper we report of the isolation and characterization of Newcastle disease viruses (NDV) obtained from Eurasian collared doves during 2000-2001, and compare them to isolates obtained from feral pigeons (Columba livia) during the same period. All isolates could be classified as avian paramyxovirus type 1 (APMV1) and belonged to the pigeon variant group (PPMV1), as their haemagglutinating activity was inhibited by mAb 161/617 which is specific for PPMV1. The intracerebral pathogenicity indices ranged from 0.68 to 1.38 and all isolates contained multiple basic amino acids at the deduced cleavage site of the fusion protein, which is a typical feature of virulent viruses. Phylogenetic analysis of the isolates indicate that 18/20 of these form a separate cluster from the isolates obtained from pigeons in the same period. These findings suggest that different lineages are circulating in feral pigeon populations, and that a separate lineage affects Eurasian collared doves.

    Full Text Available The functional development of the small intestine was investigated in Japanese quail chicks subjected to simulated microgravity (hypodynamy on the second day after hatching and reared under these conditions to 63 days of age. On days 5, 7, 14, 21, 28, 35, 42, 56 and 63 the activity of brush-border-bound alkaline phosphatase (AP in the duodenum and jejunum were determined in experimental animals as well as in control quail chicks housed in a floor box during these periods. As compared with control quails the experimental animals displayed a significantly increased enzyme activity until day 42 in the duodenum and day 35 in the jejunum (P < 0.001 whereas in older quails no significant enzymatic differences between these groups was found. However, a decrease in food consumption due to a partial physical constraint cannot be excluded. Moreover, the results suggested that the activity of AP in the control birds did not change substantially during all the periods examined. In contrast, in older hypodynamy quail the AP activity significantly decreased in the duodenum on days 56 and 63 and in the jejunum on days 42, 56 and 63, respectively. These results indicate that a the enhanced intestinal function in early periods of life may reflect the higher sensitivity of small intestine to simulated weightlessness, b the decrease of the AP activity in older animals to the level of controls might be considered as a part of intestinal mechanisms involved in adaptation of quail chicks to long-term hypodynamy, c different activity of AP in the small intestine of Japanese quail may not have resulted only from hypodynamy but also due to decreased food intake.

    The Eurasian Collared Dove (Streptopelia decaocto) is one of the most successful biological invaders among terrestrial vertebrates. However, little information is available on the genetic diversity of the species. A total of 134 Eurasian Collared Doves from Europe, Asia and the Caribbean (n = 20) were studied by sequencing a 658-bp length of mitochondrial DNA (mtDNA) cytochrome oxidase I (COI). Fifty-two different haplotypes and relatively high haplotype and nucleotide diversities (Hd±SD = 0.843±0.037 and π±SD = 0.026±0.013) were detected. Haplotype Ht1 was particularly dominant: it included 44.03% of the studied individuals, and contained sequences from 75% of the studied countries. Various analyses (FST, AMOVA, STRUCTURE) distinguished 2 groups on the genetic level, designated 'A' and 'B'. Two groups were also separated in the median-joining network and the maximum likelihood tree. The results of the neutrality tests were negative (Fu FS = -25.914; Tajima D = -2.606) and significantly different from zero (P≤0.001) for group A, whereas both values for group B were positive (Fu FS = 1.811; Tajima D = 0.674) and not significant (P>0.05). Statistically significant positive autocorrelation was revealed among individuals located up to 2000 km apart (r = 0.124; P = 0.001). The present results provide the first information on the genetic diversity and structure of the Eurasian Collared Dove, and can thereby serve as a factual and comparative basis for similar studies in the future.

  10. Dying, mourning, and spirituality: a psychological perspective.

    Science.gov (United States)

    Marrone, R

    1999-09-01

    Based in an unfortunate tradition that stretches back in time to Watson's behaviorism and Freud's psychoanalysis, psychology has tended to reject and to pathologize matters of the spirit. In the past 30 years, however, with the advent of what has been termed the cognitive revolution, psychology has greatly expanded the scope of its subject matter. Psychologists and thanatologists have begun to unravel the cognitive underpinnings of our assumptive world and the transformation of those underpinnings in times of crisis and stress. This article examines the cognitive basis of the spiritual experience and the use of cognitive assimilation, accommodation strategies during the process of mourning the death of a loved one, as well as during the process of living our own dying. Of special importance to mental health professionals and clergy, new research on dying, mourning, and spirituality suggests that the specific ways in which people rediscover meaning--such as belief in traditional religious doctrine, the afterlife, reincarnation, philanthropy, or a spiritual order to the universe--may be less important than the process itself. In other words, in the midst of dealing with profound loss in our lives, the ability to reascribe meaning to a changed world through spiritual transformation, religious conversion, or existential change may be more significant than the specific content by which that need is filled.

    The paper is an inquiry into the poetics of mourning and faith-based intervention in maladaptive grieving processes in Ethiopia. The paper discusses the ways that loss is signified and analyzes the meanings of ethnocultural and psychospiritual practices employed to deal with maladaptive grief processes and their psychological and emotional after-effects. Hermeneutics provided the methodological framework and informed the analysis. The thesis of the paper is that the poetics of mourning and faith-based social interventions are interactionally based meaning making processes. The paper indicates the limitations of the study and their implications for further inquiry.

    Two experiments were conducted to examine the effect of oxytetracycline-supplemented diets on mortality of young endangered masked bobwhite quail (Colinus virginianus ridgwayi). Inclusion of oxytetracycline at 200 g per ton in the feed for 6 weeks resulted in a marked, significant reduction in mortality of young masked bobwhite quail raised in captivity. Including the antibiotic in feed during the first week of life reduced mortality as effectively as feeding it for a longer period.

    2013-02-04

    Camouflage is conferred by background matching and disruption, which are both affected by microhabitat. However, microhabitat selection that enhances camouflage has only been demonstrated in species with discrete phenotypic morphs. For most animals, phenotypic variation is continuous; here we explore whether such individuals can select microhabitats to best exploit camouflage. We use substrate selection in a ground-nesting bird (Japanese quail, Coturnix japonica). For such species, threat from visual predators is high and egg appearance shows strong between-female variation. In quail, variation in appearance is particularly obvious in the amount of dark maculation on the light-colored shell. When given a choice, birds consistently selected laying substrates that made visual detection of their egg outline most challenging. However, the strategy for maximizing camouflage varied with the degree of egg maculation. Females laying heavily maculated eggs selected the substrate that more closely matched egg maculation color properties, leading to camouflage through disruptive coloration. For lightly maculated eggs, females chose a substrate that best matched their egg background coloration, suggesting background matching. Our results show that quail "know" their individual egg patterning and seek out a nest position that provides most effective camouflage for their individual phenotype. Copyright © 2013 Elsevier Ltd.

  15. Determining population trends and conservation status of the common quail (Coturnix coturnix in Western Europe

    Puigcerver, M.

    2012-01-01

    Full Text Available In this paper we review the conservation status and population trends of the common quail (Coturnix coturnix from 1900 to the present. Data are sometimes contradictory with regard to the status of this species as it has some features that make it difficult to produce reliable population estimates. Recent data clearly suggest, either at a local scale or at a trans–national scale, that the Atlantic common quail populations have remained stable in the last two decades, and that restocking practices with farm–reared quails (hybrids with the Japanese quail, Coturnix japonica do not affect our estimates. The complex movement patterns showed by this species require special attention. Analysis of ring recoveries can give important information, especially about the nomadic movement of quails in search of suitable habitats after the destruction of winter cereal crops due to harvesting. Thus, when developing a breeding distribution model for this species, continuously updated information on seasonal habitat and weather must be included for optimal prediction. Including fortnightly data of vegetation indices in distribution models, for example, has shown good results. Obtaining reliable predictions about changes in species distribution and movements during the breeding period could provide useful knowledge about the conservation status and population trends and would help in the design of future management measures.

    R. RANVAUD

    Full Text Available Farmers in the Paranapanema Valley (São Paulo, Brazil have reported problems with flocks of Eared Doves (Zenaida auriculata eating sprouting soybeans. In this region these birds breed colonially in sugar-cane, and eat four crop seeds, using 70% of the dry weight, in the following order of importance: maize, wheat, rice, and soybeans. Three weeds (Euphorbia heterophylla, Brachiaria plantaginea, and Commelina benghalensis were important. This information suggests that the doves adapted particularly well to the landscape created by the agricultural practices in the region, exploiting many available foods.

    1980-01-01

    An infectious agent was isolated from the liver of bobwhite quails (Colinus virginianus, L. 1758). The agent was sensitive to chloroform and its multiplication was inhibited by 5-iodine-2-deoxy-uridine. It passed filters with a pore diameter of 220 nm and more but not 100 nm filters. Electron microscopic examination revealed numerous nucleocapsids with hollow capsomeres and few enveloped particles in the supernatant fluids of infected cultures. The nucleocapsids were calculated to have 162 capsomeres on their surface. Using the plaque reduction method for neutralization tests no serological cross reactions could be detected between the quail isolate and sera against Marek's disease virus, turkey herpes-virus (HV), duck enteritis HV, infectious laryngotracheitis HV, amazon parrot HV, great horned owl HV, eagle owl HV, snowy owl HV, falcon HV, pigeon HV, Lake Victoria Cormorant HV, and stork HV. The isolate from bobwhite quail did only cross-react with antiserum against crane HV. It is concluded that the isolated virus is a member of the avian herpesvirus group and it is proposed to tentatively term it herpesvirus colinum (from Colinus virginianus = bobwhite quail).

    Coniine, an alkaloid of Conium maculatum (poison hemlock), was administered by gavage to immature chickens, quails, and turkeys at 0, 25, 50, and 100 mg/kg body weight. At 25 mg coniine/kg body weight, clinical signs were observed only in quails (2/10) and consisted of excitement, depression, hypermetria, seizures, opisthotonos, and flaccid paralysis. Chickens (9/10) and quails (8/10) dosed at 50 mg/kg body weight were affected, and several birds of each species died (2/10 and 5/10, respectively). Turkeys (7/10) were affected only when dosed at 100 mg/kg body weight, and quails (6/10), turkeys (4/10), and chickens (10/10) died at this dose. There were no gross or microscopic lesions. Coniine was detected in skeletal muscle and liver of birds dying after ingestion and was present in some survivors 7 days post-treatment.

  20. Spatial orientation in Japanese quails (Coturnix coturnix japonica.

    Directory of Open Access Journals (Sweden)

    Tim Ruploh

    Full Text Available Finding a given location can be based on a variety of strategies, for example on the estimation of spatial relations between landmarks, called spatial orientation. In galliform birds, spatial orientation has been demonstrated convincingly in very young domestic chicks. We wanted to know whether adult Japanese quails (Coturnix coturnix japonica without food deprivation are also able to use spatial orientation. The quails had to learn the relation of a food location with four conspicuous landmarks which were placed in the corners of a square shaped arena. They were trained to find mealworms in three adjacent food cups in a circle of 20 such cups. The rewarded feeders were located during training between the same two landmarks each of which showed a distinct pattern. When the birds had learned the task, all landmarks were displaced clockwise by 90 degrees. When tested in the new situation, all birds redirected their choices with respect to the landmark shift. In subsequent tests, however, the previously correct position was also chosen. According to our results, quails are using conspicuous landmarks as a first choice for orientation. The orientation towards the previously rewarded location, however, indicates that the neuronal representation of space which is used by the birds also includes more fine grain, less conspicuous cues, which are probably also taken into account in uncertain situations. We also presume that the rare orientation towards never rewarded feeders may be due to a foraging strategy instead of being mistakes.

  2. Path(os of Mourning. Memory, Death and the Invisible Body in Derek Jarman’s Blue

    Directory of Open Access Journals (Sweden)

    Nicoletta Vallorani

    2010-10-01

    Full Text Available The essay addresses two quite complex issues. The first one is the virulence of the hostility toward  gay men that the AIDS pandemic has released: this is the backdrop against which Jarman's extended elaboration and mourning for his own death  is performed, after his diagnosis as body-positive in 1986. The second issue  links to the open question of public mourning and its relation to AIDS in the early 90s, when the AIDS epidemic is not at its height, but it is certainly more visible than before, and many artists register the impact of the new sensibility this medical and social emergency actually moulds.  Considering a specific time span (the 90s and  focusing mostly on cinema a strategic, privileged arena where gay cultures resist to social and cultural sanctions, this work elaborates on how AIDS as a deathly social and cultural destiny has suggested strategies of mournings that introduce new artistic practices. The analysis is specifically focused on Derek Jarman's last works, culminating in the film Blue (1993.

Based upon estimates of the median lethal dosage, there was up to a two-fold enhancement of parathion toxicity in birds chronically exposed to heat or cold. Twenty-four hours after administration of a low dosage (4 mg/kg body wt, po), there was markedly greater cholinesterase inhibition in surviving heat-exposed quail compared with those reared at 26.degree. C (e.g., brain acetylcholinesterase depression of 42% versus 12%). There were no differences in hepatic activities of parathion oxidase, paraoxonase, or paraoxon deethylase which could account for greater toxicity to chronically heat-exposed birds. In contrast, 4 mg parathion/kg wt elicited less plasma cholinesterase inhibition in cold-exposed quail compared to thermoneutral controls (e.g., birds is substantially influenced by environmental temperature.

    Full Text Available Aiming to assess isoleucine levels in low protein diets for laying Japanese quails, 648 quails of 182 days of age were distributed in experimental block design with six treatments and six replicates of 18 birds each. Treatments consisted of a basal level corresponding to 0.672% isoleucine and supplemented with isoleucine to the levels of 0.816, 0.960; 1.104; 1.248%. The experimental diets were compared to a control diet containing 20% CP. The parameters studied were: performance, egg quality, total solids and nitrogen in the excreta. There was a linear increase only for isoleucine intake with increasing levels of isoleucine in the diets. The comparison of mean values of each combination of isoleucine levels for diets with 16% CP with the control with 20% CP showed that the intake of CP and isoleucine, egg weight, nitrogen excretion and yolk color were significantly affected. For Japanese quail fed diets with 16% CP, with isoleucine level at 0.672%, meets the requirements for obtaining satisfactory performance and egg quality and promoted a reduction in nitrogen excretion.

    This article uses the dual process model (DPM) in an analysis of the national mourning of tens of thousands of disappeared in Chile and Argentina by adapting the model from the individual to the collective level where society as a whole is bereaved. Perpetrators are also involved in the national mourning process as members of a bereaved society. This article aims to (a) demonstrate the DPMs significance for the analysis of national mourning in post-conflict societies and (b) explain oscillations between loss orientation and restoration orientation in coping with massive losses that seem contradictory from a grief work perspective.

    Full Text Available Threonine, like most amino acids, is traditionally noted for its role in protein synthesis. However, dietary threonine concentration required for the maximum performance of Japanese quails is yet to be determined, therefore, a study was conducted to determine the optimum threonine requirement of Japanese quail chicks in the tropical environment. A total of four hundred and fifty, two weeks old quail chicks (mixed sexes were randomly allocated to five dietary treatments (0.67, 0.81, 0.95, 1.08 and 1.22 % total threonine and replicated thrice in a completely randomized design (CRD. There were no significant differences (P>0.05 in average weight gain, average feed intake, feed conversion ratio and age at first lay of quails fed the dietary treatments. Weight of first egg laid was significantly (P0.05 similar for all treatments. There were significant differences (P0.05. It was concluded that the performance of birds were not influenced by the dietary treatments up to the highest dietary level of threonine studied (1.22%. Therefore, it is possible that the optimum dietary level of threonine may be above 1.22 %. Further studies will be necessary to establish higher doses of dietary threonine requirement of Japanese quails reared under tropical climatic environment.

    Full Text Available ABSTRACT This study was conducted to investigate the effects of transient treatment with propylthiouracil (PTU on some reproduction traits and live weight of quails. The trial lasted 8 weeks. To accomplish this goal, 700 1-day-old quail chicks were used, randomly divided into 8 groups. PTU was added to feed by 0.1% and 0.5% /wt. The first 4 groups had 0.5% PTU at the age of 2-4, 4-6, 6-8 and 2-8 wk., respectively. The 5 th, 6 th and 7 th groups had 0.1% PTU at the age of 2-4, 4-6 and 6-8 wk., respectively, and the 8 th group was the control with no PTU. Quails were bled at 60 days of age. Then right and left testes were taken out and weighed. At the end of the trail, least square means of the live weight of the treatment groups were higher than the control (p<0.05. Similar results (p<0.05 were observed for testis weight, testis diameter and fertility rate. As a result, it can be said that the inclusion of PTU in quail rations positively affects the live weight and reproduction traits of quails.

    Stress-induced glucocorticoids can dampen learning and spatial memory via neuronal damage to the hippocampus. Cognition losses can be transient (associated with acute stress episodes) or permanent as in aged individuals who show chronic glucocorticoid-induced accelerated brain aging and neurodegeneration (dementia). Thus, chronic versus acute stress effects on spatial memory responses of quail selected for reduced (low stress, LS) or exaggerated (high stress, HS) plasma corticosterone (B) response to brief restraint were assessed. Aged food-motivated male LS and HS quail were tested for 10 min in a feed-baited 8-arm radial arm maze (RAM) 1) at 255 d of age (quail who had experienced lifelong management stressors but who were otherwise never intentionally stressed; that is, chronically stressed birds), 2) on the next day post-acute stressor treatment (5 min of restraint), and 3) on the next day without treatment (acute stress recovery). The RAM tests used the win-shift procedure in which visited arms were not rebaited. Radial arm maze performance was measured by determination of the total number of arm choices made, the number of correct entries made into baited arms out of the first 8 choices, the time required to make a choice, and the number of pellets eaten. Line effects (P LS), and number of pellets eaten (HS RAM testing nor its interaction with line further influenced these variables. Thus, although selection for divergent plasma B responsiveness to an acute stressor was found to be associated with severe impairment of spatial memory in aged male HS compared with LS quail, the observed spatial memory impairments (HS > LS) could not be further altered by acute stressor treatment. Line differences in cognition may reflect lifelong management-induced stress episodes that periodically produce higher plasma B responses in HS than LS quail, which underlie HS quail memory deficits, or other etiologies, or both.

    The objective of this study was to evaluate the effect of feed supplement (FS) contained earthworm meal (EWM) on production performance of laying quails. Twenty weeks-old of 360 Coturnix coturnix japonica quails were used in a Completely Randomized Design (CRD) with three dietary treatments A = CD (control without FS), B = CD + 0.250 % of FS, and C = CD + 0.375 % of FS during 6 weeks of experimental period. Each treatment in 4 equal replicates in which 30 quails were randomly allocated into 12 units of cages. Variable measured were feed intake, feed conversion ratio, feed efficiency, mortality rate, hen day production, egg weight, and egg uniformity. Data were statistically analyzed by One Way ANOVA and the differences among mean treatments are analysed using Duncan’s Multiple Range Test (DMRT). The results showed that administration of 0.375% FS based on earthworm meal, fermented rice bran, and skim milk impaired the feed conversion ratio and increased the feed efficiency. The experimental treatments did not effect on feed intake, mortality, hen day production, egg weight, and egg uniformity of quail. It is concluded that administration of feed supplement improved the growth performance of quail.

    The aim of the present study was to evaluate the effect of lighting programs for male and female meat quails raised in an equatorial region on performance and carcass traits. A total of 1,500 sexed quails (Coturnix coturnix) was distributed in a completely randomized design in a 2 × 3 factorial arrangement, with 2 sexes (male and female) and 3 lighting programs (natural, intermittent, and continuous) with 5 replicates of 50 birds. The lighting programs were applied in the period from 7 to 49 d of age, being natural (12 h and 30 min of natural light and 11 h and 30 min of dark), intermittent (12 h and 30 min of natural light and 5 h and 30 min of artificial light, alternating lighting periods with one h and 06 min and periods of darkness with one h and 12 min), and continuous (23 h of natural + artificial light and one h of dark). Regardless of lighting program, female quails were heavier than males, and birds subjected to natural light weighed less than those exposed to continuous and intermittent lighting programs. Quails exposed to intermittent and continuous light presented higher weight gain and feed intake, and worse feed conversion ratio compared to birds under a natural light regimen. It is concluded that in an equatorial region, it is possible to use a lighting program with only natural light for raising male and female meat quails from 7 to 49 d of age. © 2017 Poultry Science Association Inc.

    The gut microbiota is involved in host behaviour and memory in mammals. Consequently, it may also influence emotional behaviour and memory in birds. Quail from two genetic lines with different fearfulness (LTI: long tonic immobility, n=37; STI: short tonic immobility, n=32) were either or not supplemented with a probiotic (Pediococcus acidilactici) from hatching. Emotional reactivity was measured in a tonic immobility test (d6 and 7 of age) and two open-field tests (d13-15; d22-24). Memory was measured in a test rewarded with mealworms, where quail had to remember the cups previously visited (d34-36). Quail endured a 5-days stress period from days 17 to 21 to help revealing the potentially beneficial effect of the probiotic. As expected, STI quail were less fearful compared to the LTI quail (p0.05), except in the tonic immobility test where supplemented STI quail had lower immobility duration (p=0.0001). Regarding the memory test, the two lines had similar performances. Quail fed with probiotics made fewer errors (p=0.040). There was no significant correlation between traits of emotional reactivity and of memory. In conclusion, the supplementation with Pediococcus acidilactici as a probiotic, affected a specific trait of emotional reactivity in STI quail, and improved memory in both lines, whichstrengthens the idea that the influence of gut microbiota on the host behaviour and memory seen in mammals is shared by birds.

    Background: Quail eggs contain a considerable amount of complete nutritional sources such as carbohydrates, proteins, fats, and micronutrients. However, they also have a high cholesterol level, which can potentially cause atherosclerosis and chronic heart diseases. The response of the body to foods containing is influenced by factors such as ethnicity, genetics, and hormonal and nutrient status of the consumer. The cholesterol level of quail eggs can be reduced by manipulating the feed using supplemental organic feed. Organic quail eggs have been believed to correct the lipid profile of white mice during the lactation phase. Purpose: The aim of this study was to analyze the effect of feed containing organic quail eggs on the blood lipid profile of white mice (Rattus norvegicus L.) during the lactation phase. Materials and Methods: This experimental study was conducted using a completely randomized design with four experiments and five repetitions. Experimental mice: T0 mice were used as control; T1 mice were supplemented with quail eggs produced by quails that were fed with standard feed; T2 mice were supplemented with eggs produced by quails fed with standard organic feed; and T3 mice were supplemented with eggs produced by quails fed with organic feed with the addition of cassava leaf flour, mackerel flour, and turmeric powder. Quail egg supplementation was administered to the mice from the early pregnancy period till the end of the lactation phase. The acquired data were analyzed using ANOVA. SPSS version 16.0 software for Windows was used for data analyses. Results and summary: Feeding the white mice with different compositions of organic quail egg supplements had no effect on the consumption of feed and water, body weight, and lipid profile (including total cholesterol, LDL, HDL, and triglyceride) during the lactation phase (P > 0.05).

    The effect of different doses of gamma irradiation on the embryonic development of quail and hen's eggs was examined. The goals of the examinations were to determine the LD 50 and LD 100 values, to establish the effect of single and multiple irradiation on embryonic development and to get some information on the embryonation of eggs produced by quails and their progeny grown from irradiated eggs. It was shown that 200 rad dose has significant stimulation effect of the hatching results of quail eggs. The LD 50 and LD 100 values were about 800 to 850 rad and 1600 rad, respectively. Repeated irradiation on the progeny-generations proved to be unambiguously deleterious on embryonation. High doses changed the rhythm of embryonal mortality, showing a peak under the irradiation and in the first three days of incubation, and significantly enhanced the number of teratological types.

    This investigation aims to study the possibility of using gamma irradiation for improving the microbial safety quality of quail carcasses. One hundred quail carcasses were examined for the presence of salmonella. The examination illustrated that 70 carcasses from all examined carcasses were positive for salmonella. therefore, the contaminated quail carcasses were gamma irradiated at 2, 4 and 6 kGy doses and the effects of these treatments on the microbiological aspects and chemical properties of samples under investigation were evaluated. The results indicated that, the chemical composition of samples did not alter by gamma irradiation treatment. Furthermore, irradiation of samples at doses of 2, 4 and kGy greatly reduced its microbial count. Moreover, irradiation doses of 2 and 4 kGy completely destroyed salmonella and enterococcus faecalis, respectively. In addition, the acid value, peroxide value and thiobarbituric acid value were increased after irradiation. On the other hand, irradiation treatment had no real effects on the total volatile basic nitrogen content and amino acid composition of samples under investigation

    Full Text Available ABSTRACT: This trial was carried out to evaluate the effects of dietetic metabolizable energy levels on performance and carcass traits of meat quails from 15 to 35 days old. Five hundred sixty, 15-d old, meat quails were randomly assigned to five treatments (2.850; 2.950; 3.050; 3.150 e 3.250kcal of ME kg-1 of diet, with eight replicates and fourteen birds per experimental unit. Feed intake, protein and lysine intake and feed conversion decreased linearly as the metabolizable energy content of diets increased (P0.05 by the treatments. Diets did not influence (P>0.05 carcass traits as dry matter, moisture and protein content in carcass. However a quadratic effect (P<0.04 were observed on carcass fat content. Based on these results, the adequate metabolizable energy level to ensure better meat quails' growth is 3.250kcal of ME kg-1 diet, that corresponds to a metabolizable energy: crude protein ratio of 139,24.

    The study was conducted to evaluate the feed efficiency of quail diets containing different concentrations of metabolizable energy (ME) and crude protein (CP) with constant ratio and supplemented with methionine. Four hundred laying quails (Coturnix coturnix japonica) were randomly assigned to four experimental diets in a 2×2 factorial arrangement. Each dietary treatment used 5 replicates of 20 quails. Two basal diets were formulated to contain 2,800 kcal kg-1 ME and 18.7% CP (High ME-CP) and 2,600 kcal kg-1 ME and 17.3% CP (Low ME-CP). Each basal diet was supplemented with 0 and 0.12% methionine. The High ME-CP diets generated lower feed consumption but higher egg mass and feed efficiency (Pprotein efficiency ratio (PHigh ME-CP supplemented with methionine resulted the highest feed efficiency followed by the Low ME-CP supplemented with methionine, while both High ME-CP and Low ME-CP without methionine supplementation resulted the lowest feed efficiency (PHigh ME-CP supplemented with 0.12% methionine provided benefit to improve the feed efficiency in laying quails.

Data on egg production, feed conversion (kg feed intake/kg eggs and dozen eggs, egg weight, egg specific gravity, eggshell thickness and weight, Haugh unit, yolk index, albumen index and mortality (% of 144 quails were evaluated for 112 days, divided in eight cycles of 14 days. Birds were distributed according to a randomized block experimental design into four treatments (control; 0.3ppm Se; 60ppm Zn and 0.3ppm Se + 60ppm Zn with six replicates each. There were no differences (p> 0.05 in egg production (%, egg mass (g/hen/day, feed conversion per egg mass (kg/kg, feed conversion per dozen eggs (kg/dz, average egg weight (g, egg specific gravity, eggshell thickness and weight (g, Haugh unit, yolk index, albumen index and mortality (%. However, quails fed the combination of Se and Zn presented higher (p < 0.05 feed intake (28.73 g/hen/day. Those fed only organic selenium had higher average daily egg production (30.17 eggs/day, and those fed the diet only supplemented with zinc presented higher mortality (p < 0.05. The results of the present study suggest that the supplementation of organic trace minerals in Japanese quails diets submitted to heat stress does not significantly influence quail performance and internal egg quality, whereas the supplementation of the combination of organic Zn and Se increases feed intake.

    A total number of 800 Japanese quail eggs were obtained from a parent flock maintained the poultry research unit of the Biological Application Department, Nuclear Research Centre at Inshas, Egypt, and used in the present study. Before incubating the eggs, they were divided into two equal groups of 400 eggs each; the 1 st group was exposed to a low level of gamma irradiation at 50 rad before sitting while the 2 nd group did not exposed to gamma irradiation. After hatching of the two groups, fertility, hatchability, embryonic mortality and hatching weight were determined. Hatched quail chicks from each group (1 and 2) were divided into four identical subgroups and all fed the basal diet but with a different supplement. The diet of the 1 st subgroup was supplemented with 2.5% Lactobacilli, the 2 nd with 1.5% lactose, the 3 rd with 2.5% Lactobacilli plus 1.5% lactose, while the 4 th subgroup was fed the basal diet only and served as control. The results showed decreased embryonic mortality and increased hatchability and hatching weight due to exposing quail eggs to low level of gamma radiation as compared to non-exposed eggs. The average body weight and the relative weights of carcass, testis and oviduct, egg production, egg weight, serum total protein, albumin, globulins, RBC, WBC and Hb values were increased significantly (P th week due to adding Lactobacilli and lactose to the basal diet. Significant reduction (P<0.05) in the intestinal wall index was observed due to adding Lactobacilli and lactose to the basal diet of hatched quails. In conclusion, adding Lactobacilli and/or lactose to the basal diet of hatched Japanese quails improved performance as well as blood constituents and intestinal wall index. The magnitude of this improvement was even greater when both supplements were combined. In addition, the exposure of eggs to low level of gamma radiation (50 rad) improved hatchability and hatching weight of Japanese quail eggs, but no relationship to dietary

    Full Text Available The shelf-life of 3 batches (Q1, Q2, Q3 of quail meat, were examined. Q1 were cut and seasoned with commercial olive oil, stoned green olive and sliced bacon. Q2 were divided into two subgroups: Q2.1 produced in the previously described conditions; Q2.2 seasoned also with rosemary. Quails were placed in lowdensity polystirene barrier trays and aerobically packaged. Q3 quails were boiled in salted hot water for 40 min, seasoned with myrtle leafs, placed in low density polyethylene bags and vacuum packaged. All samples were stored at +2 and +7°C. Analysis were conducted at 0, 3, 7, 9 and 14 days (T0, T3, T7, T9, and T14, respectively. For all the samples, pH measurement and microbial analysis [total viable count (TVC, Enterobacteriaceae, E. coli, Lactobacillus spp. (LAB, Pseudomonas spp., Brochothrix thermosphacta, coagulase-negative Staphylococci (CNS, Enterococcus spp., yeasts and moulds, Salmonella spp., Listeria monocytogenes] were performed. Initial TVC levels of fresh quails (ca. 4 log CFU/g were rather high and this may be due to the microbial population of the raw material. In Q1 and Q2.1 samples, TVC reached the value of 7 log, which is considered as the upper acceptability limit for fresh poultry meat (after T9 under storage at +2°C and after T7 at +7°C. In Q2.2 samples such limit was reached earlier, after T3. In Q3 samples, lower TVC levels were recorded and did not reach the above mentioned limit, not even at the end of storage. However, mean counts >5 log were reached, maybe because of a post-cooking cross-contamination. Salmonella spp. prevalence was 33% in Q1, Q2.1 and Q2.2 samples.

    In Japanese quail, we previously described a sexual dimorphism of the parvocellular vasotocin system of the limbic region that, as the reproductive behavior, is steroid-sensitive and is organized during embryonic life by the exposure to estradiol. We verified in this study whether diethylstilbestrol, a chemical xenoestrogen, has analogous organizational effects on the vasotocin system of limbic regions and on copulatory behavior of male Japanese quail. We injected in the yolk sac of 3 day-old quail embryos diethylstilbestrol or estradiol benzoate (a treatment which suppresses male copulatory behavior in adulthood and reduces vasotocin innervation), or sesame oil (control). No further hormonal manipulations were performed after hatching. Sexual behavior was recorded in males at the age of 6 weeks. Estradiol- and diethylstilbestrol-treated males exhibited a total suppression of copulatory behavior. After behavioral tests, all males were sacrificed and brain sections processed for vasotocin immunocytochemistry. Significant decrease in the density of vasotocin immunoreactivity was detected in the medial preoptic nucleus, in the bed nucleus of stria terminalis, and in the lateral septum of diethylstilbestrol-treated males. The magnocellular vasotocin neurons were, in contrast, not affected. In conclusion, the present data demonstrate that embryonic treatment with diethylstilbestrol induces a full sex reversal of behavioral phenotype as well as a significant decrease of vasotocin expression in the preoptic-limbic region in male Japanese quail. Therefore, the parvocellular vasotocin system could represent an optimal model to investigate the effects of pollutants on neural circuits controlling reproductive functions.

    Full Text Available Descendants ( of S18 generation of Japanese quails (Coturnix coturnix japonica, selected for low (line 11, n=15 or for high (line 12, n=6 yolk cholesterol content were used for this experiment. The high (12 and low (11 lines were developed from a control egg type (line13 wild color plumage stock 07, from Poultry Breeding Station in Ivanka at Danube (Slovakia that was maintained without conscious selection. The results of selected lines were compared to this one from unselected lines, egg type (line 13, n=15 and meat type (line 8, n=15, to study productive performance (growth and carcass weight as well as meat quality traits (intramuscular collagen properties, fatty and cholesterol content. The birds were grown up to 35 days of age. Quails were fed ad libitum with commercial diets according to their ages. Animals had free access to water during the experiment. The body weight of the quails was controlled every week (from week 1 to 5. At the slaughter (at avg. weight of 104.0, 107.7, 110.6 g vs 209.3 g for lines 11, 12, 13 vs 8, respectively; P<0.05 the hot carcass weight was recorded and dressing percentage was calculated. Pectoralis superficialis muscles were removed from the carcasses to assess intramuscular collagen (IMC properties (collagen and crosslink concentrations, intramuscular lipid and cholesterol contents. Growth and slaughter performance, intramuscular fat percentage and IMC properties of Pectoralis superficialis were not different between the birds selected for low (line 11 and high (line 12 yolk cholesterol content and were also found to be similar between the quails of egg type and those selected for yolk cholesterol content (lines 11 and 12. Compared to the birds of egg type line and those selected for yolk cholesterol content, the quails of meat type had higher growth and carcass traits (P<0.05, while meat quality traits were found to be similar.

    Full Text Available The main purpose of this study is to extend the microscopic investigations of the pecten oculi in the quail in order to add some information on the unresolved functional anatomy of this unique avian organ. The pecten oculi of the quail was studied by scanning electron microscopy. Eighteen- to-twenty two highly vascularised accordion-like folds were joined apically by a heavily pigmented bridge of tissue, which holds the pecten in a fanlike shape, widest at the base. The structure of the double layered limiting membrane was recorded. The presence of hyalocytes with macrophage-like appearance was illustrated. It is assumed that the pecten oculi of the quail resembles that of the chicken. Illustrated morphological features of this species may add information on the active physiological role of the pecten. But still, the functional significance of this organ is a matter of controversies.

    The experimental work aimed at the quantitative ultrastructure of the myocardial cells of the Japanese quail Coturnix coturnix japonica during hypergravitation, hypodynamism and space flight in a Soviet satellite. For the determination of quantitative changes of the myocardial ultrastructure a morphometrical method was used with parameters like the number of mitochondria, average mitochondrial size, relative mitochondrial volume, deficiency of cristae and relative volume of myofibrils. The quails were observed in 3 groups. The absolute control consisted of quails living in normal Earth conditions, in the laboratory group the quails were exposed to conditions of hypergravitation and hypodynamism in a specially constructed centrifuge, and in the flying group the quails were exposed to space flight in a Soviet orbital station MIR. In the group of absolute controls no pathological changes of the myocardial ultrastructure were found. In the flying group there were no significant changes, with the exception of decreased relative volume of myofibrils, which however agrees with the findings on symptoms corresponding to human and animal heart weakness during space flights. In the laboratory group, pathological changes were observed in each of the fractions. The most significant pathological findings were found in the group controls in the center and in hypergravitation combined with hypodynamism. It can be concluded that the laboratories can simulate conditions induced by the start and flight of space ships. (Fig. 2, Ref, 8.)

    1996-02-01

    Site faithfulness and general movement patterns of five rock dove (Columba livia) flocks were estimated in order to evaluate their efficacy as radiological indicators on the Hanford Site. Of 367 individually marked birds, 311 were resighted or recaptured at least once during onsite and offsite monitoring. Average site faithfulness for all flocks from resightings was 87.1% and was not significantly different than a hypothesized 90% site faithful distribution. Average site faithfulness from pooled resightings and recaptures was 91.3%, which was also not significantly different than a 90% distribution. Since Hanford rock doves exhibit site faithfulness and can be easily monitored, I conclude that they can be used as radiological indicators. I found 107 birds at 21 different locations during offsite surveys in agricultural areas adjacent to the Hanford Site. Mean movement distances from capture areas to offsite locations for each of the five flocks were significantly different. Mean movement distances from capture areas to offsite locations for each flock were highly correlated with closest possible distances for each flock. Mean movement directions from capture areas to offsite locations for each flock were significantly different than random movement patterns for each flock.

    Full Text Available Katuk (Sauropus androgynus L Merr is known to contain carotenoids, vitamin E, vitamin C, protein and phytosterol compound. This study was aimed to determine the ability of phytosterols in Sauropus androgynus (SA leaf to obtain poultry product that has low cholesterol content. One hundred fifty female quails were raised from 2-27 weeks old, divided into three treatment diets, five replicates with 10 quails in each replicate. The treatment diets were: 1 Control group: diet without katuk leaf meal; 2 Diet with 9% SA ethanol 70% extract (SAE; 3 Diet containing 9% SA meal (SAM. Kolesterols were determined with CHOD-PAP-Method by Human, there is enzymatic Colorimetric Test for Cholesterol with Lipid Clearing Factor. The result showed that total cholesterol in the egg yolk, carcass and liver of SAE and SAM treated quails were lower (P<0.05 than that of the control-treated quails, except the cholesterol content in the serum. These findings indicated that the cholesterol concentration of female quails was decreased due to phytosterol content in katuk leaf.

    State dependent learning effects have been widely studied in a variety of drugs of abuse. However, they have yet to be studied in relation to sexual motivation. The current study investigated state-dependent learning effects of cocaine in male Japanese quail (Coturnix japonica) using a sexual conditioning paradigm. Cocaine-induced state-dependent learning effects were investigated using a 2×2 factorial design with training state as one factor and test state as the other factor. During a 14-day training phase, male quail were injected once daily with 10mg/kg cocaine or saline and then placed in a test chamber after 15min. In the test chamber, sexual conditioning trials consisted of presentation of a light conditioned stimulus (CS) followed by sexual reinforcement. During the state dependent test, half of the birds received a shift in drug state from training to testing (Coc→Sal or Sal→Coc) while the other half remained in the same drug state (Coc→Coc or Sal→Sal). Results showed that male quail that were trained and tested in the same state (Coc→Coc or Sal→Sal) showed greater sexual conditioning than male quail that were trained and tested in different states (Sal→Coc) except when cocaine was administered chronically prior to the test (Coc→Sal). For the latter condition, sexual conditioning persisted from cocaine training to the saline test. The findings suggest that state dependent effects may alter sexual motivation and that repeated exposure to cocaine during sexual activity may increase sexual motivation which, in turn, may lead to high risk sexual activities. An alternative explanation for the findings is also discussed. Copyright © 2014 Elsevier Inc. All rights reserved.

  19. Sex Determination of Japanese Quails (Coturnix Coturnix Japonica using with Zoometric Measurements

    2017-09-01

    Full Text Available The difficulty of sex determination in most poultry species causes significant financial losses for poultry production as birds cannot be separated at early stages of growth for meat or egg production. Therefore it is important to determine bird’s sex with zoometric parameters. This study was carried out to determine the sex of Japanese quails with zoometric measurements, such as live weight, body length, chest depth and chest width. Eighty-eight male and female Japanese quail chicks were used individually for live weight, chest depth (mm, chest width (mm and body length (mm with using digital scaled balance and caliper for every week over a period of six weeks. The weekly collected data were applied to t test for estimating the sex discrimination. The Pearson’s correlation was applied for examining the interrelationship between sex and biometric traits. The results indicated that there was a significant positive correlation between live weight and body length beginning with the 2nd week. Therefore, zoometric measurement of these body traits is suitable for discriminating the sex of Japanese quails in early phase of life.

    2014-06-01

    Full Text Available Antibacterial, anti-inflammatory and antiparasitic properties have been associated with the extract of pomegranate (Punica granatum in several animals and conditions. The Japanese quail (Coturnix japonica, originated from North Africa, Europe and Asia, is used worldwide as an experimental animal and model for aviculture. The current study investigated the effects of the pomegranate pericarp aqueous extract on the shedding, viability and morphometry of three Eimeria spp. from Japanese quails, besides the weight gain and genotoxic activity. Although the pomegranate is recognized by multiple properties, including anti-coccidial, in the current study the results are contrary. The treated group shed greater amount of oocysts; the sporulation times and viability were similar in both groups; despite some morphometric differences, these were not expressive; weight gains were similar; and the pomegranate had insignificant effect genotoxic. Finally, these results suggest that the pomegranate pericarp extract did not influence on Eimeira spp. from Japanese quails; therefore, the pomegranate pericarp extract is not suggested in the prevention/treatment of coccidiosis in Japanese quails, or at least not using methods of preparation and administration applied in this study.

    Full Text Available En el presente texto se articulan desarrollos realizados por Freud y Lacan a propósito del duelo con el fin de responder a la relación entre éste y lo que Lacan propone en Televisión sobre la tristeza y el rechazo del inconsciente. Para tales fines, se parte de las preguntas e intentos de respuestas dadas por Freud en el plano de la economía libidinal a propósito del duelo, para pasar a los desarrollos de orden ético y moral que Lacan plantea a propósito de la tristeza. De esta forma, el rechazo del inconsciente presente en las psicosis se distingue del que tiene lugar en el duelo, al considerar la tristeza un afecto que dará cuenta del rechazo del deseo del Otro. // This text articulates developments made by Freud and Lacan about mourning to attempt a response on how this relates to Lacan‟s proposal in Television about sadness and rejection of the unconscious. To do this, the text departs from the questions and answers given by Freud in the field of the economy of the libido referring to mourning and then moves on to the ethical and moral aspects that Lacan refers about sadness. Consequently, from this perspective the rejection of the unconscious in the psychosis is different from the one that takes place in mourning, considering sadness as an affection that will evidence the rejection of the desire of the Other.

    Forty-eight scaled quail (Callipepla squamata) were collected during August 2002 at Elephant Mountain Wildlife Management Area in Brewster County, Texas, and examined for helminths. Eight species of helminths were found (5 nematodes and 3 cestodes), representing 2,811 individuals. Of these species, Gongylonema sp., Procyrnea pileata, and Choanotaenia infundibulum are reported from scaled quail for the first time. Prevalence of Aulonocephalus pennula, Gongylonema sp., Oxyspirura petrowi, Physaloptera sp., P. pileata, C. infundibulum, Fuhrmannetta sp., and Rhabdometra odiosa was 98, 2, 56, 4, 60, 2, 25, and 35%, respectively. Aulonocephalus pennula numerically dominated, accounting for 88% of total worms. Statistical analyses were performed on the 5 species with > or = 25% prevalence using the after-hatch-year host sample (n = 38). Prevalence of P. pileata was higher (P = 0.049) in females than in males and higher (P = 0.037) in the sample collected from the site that had spreader dams (berms 1-2 m high and 4-55 m long constructed in varying sizes to catch and retain rainfall) than the control site (no spreader dams). Higher rank mean abundance of A. pennula and O. petrowi (P = 0.0001 and P = 0.0052, respectively) was found in the host sample collected from the site that had spreader dams than the control site. A host gender-by-collection site interaction (P = 0.0215) was observed for P. pileata. Findings indicate that scaled quail are acquiring indirect life cycle helminths in arid western Texas habitats.

The analysis and assembly of the generated sequences is ongoing. Access to the whole genome sequence from these two species will enable enhanced...... comparative studies towards the chicken genome and will aid in identifying evolutionarily conserved sequences within the Galliformes. The obtained sequences from quail and partridge represent a beginning of generating the whole genome sequence for these species. The continuation of establishing the genome...

  7. COMPARATIVE EFFICACY OF DETOMIDINE AND DETOMIDINE - KETAMINE COCKTAIL IN QUAILS

    Directory of Open Access Journals (Sweden)

    U. F. Durrani, M. Ashraf and A. Khalid¹

    2005-10-01

    Full Text Available Twenty adult healthy quails (Coturnix coturnix were divided into two equal groups. One group was administered detomidine (2.4 mg/kg, I/M and other group was administered detomidine-ketamine cocktail (1.2 mg/kg + 30 mg/kg, I/M. Detomidine slowly and smoothly induced a light sedation accompanied by superficial analgesia, hypoventilation, hypothermia and bradycardia in all birds. Detomidine-ketamine cocktail rapidly and smoothly induced a deep anaesthesia accompanied by deep analgesia, hypoventilation, hypothermia and bradycardia and complete loss of all reflexes in all birds. In both groups, recovery from sedation and anaesthesia was smooth and of short duration. From this study it was concluded that for minor and least painful procedures in quails detomidine can be used alone, while for major and painful surgical procedures detomidine-ketamine combination should be preferred.

    2014-08-01

    The current research was conducted to compare growth, carcass traits, pH, intramuscular collagen (IMC) properties, and genetic bases of IMC and carcasses (breast-muscle weight) of different lines and generations of adult males and females of Japanese quail (Coturnix japonica). Forty-four quails (generation F0), 22 Pharaoh (F-33) meat-type males and 22 Standard (S-22) laying-type females, were crossed to produce the F1 hybrids generation. The F2 generation was created by mating one F1 male with one F1 female, full siblings. The birds, randomly chosen from F0 (22 males and 22 females), F1 (22 males and 22 females), and F2 (84 males and 152 females) were raised to 20 wk of age in collective cages. Quails were fed ad libitum commercial diets. At slaughter, all birds were individually weighed (after a fasting period of 12 h) and dressing yield (without giblets) was calculated. The carcasses were then dissected. Genomic DNA was extracted from all of the blood, and 30 microsatellite markers located on 2 quail chromosomes were genotyped. The F -: 33 quails had higher in vivo and postmortem performances and a higher abdominal fat percentage than those of the egg line. Meat from S -: 22 quails had a slower collagen maturation (hydroxylysylpyridinoline crosslink/collagen) and a higher ultimate pH. The F1 and F2 generations showed an evident sexual dimorphism, and an additional effect could be due to hybrid heterosis evident in F2. Meat from quails of F1 and F2 generations had a lower IMC amount with a higher degree of collagen maturation compared with parental lines. Two statistically significant QTL have been detected on quail chromosome 2 (CJA02): a QTL with an additive effect (0.50) for IMC in the marker bracket GUJ0037 and GUJ0093; a second QTL with additive (1.32) and dominant (1.91) effects for breast-muscle weight in the marker bracket GUJ0084 and GUJ0073. To our knowledge, this is the first report of a QTL associated with breast-muscle weight and IMC in quail and

  12. Opportunities for mourning when grief is disenfranchised: descendants of Nazi perpetrators in dialogue with Holocaust survivors.

    Science.gov (United States)

    Livingston, Kathy

    2010-01-01

    This article explores the concepts of unmourned and disenfranchised grief as a way to understand the experiences of adult children of Nazi perpetrators, who grew up with cultural norms of grieving alone or in silence. The scholarly literature on descendants of Nazis reflects a group unlikely to warrant empathy or support from others because of the stigma surrounding their family's possible involvement in the Holocaust atrocities. This article uses, as a case study approach, the testimony given by Monika Hertwig, the adult daughter of a high ranking Nazi, who appears in the documentary film, Inheritance. From the perspective of disenfranchised grief, defined as grief that is not socially recognized or supported, the article links Monika's testimony with existing research from in-depth interviews with other descendants of Nazis to suggest that, as a group, they lacked permission to grieve their deceased parents, acknowledgment of their grief, and opportunities to mourn. Based on the theory that the effects of grief can be transgenerational, the disenfranchisement experienced by the "children of the Third Reich" does not have to pass to subsequent generations if opportunities for mourning are made possible and some resolution of grief occurs. Studies have shown that ongoing dialogue groups between Holocaust survivors and descendants of Nazis provide opportunities for mourning to both groups.

    Full Text Available The aim of the current work was to examine the influence of Bulgarian phytoproduct VemoHerb T (dry extract of Tribulus terrestris –TT on laying productivity of Japanese quails (Coturnix coturnix japonica and their egg morphological and sensor properties. A trial was organized with 52 female and 16 male Japanese quails from the breed Faraon at the age of 44 days randomly divided in four groups – control and three experimental groups, 13 female and 4 male each. All birds were fed ad libitum the same compound feed for Japanese quails. The trial lasted 10 weeks. The experimental groups received with the drink water the tested product in following daily doses: 4mg/kg body weight (10weeks; 10mg/kg body weight (the first 5 weeks of the trial; 10mg/kg body weight (10 weeks for Ist, IInd , IIInd experimental groups respectively. The addition of TT-extract improved significantly the laying productivity. It was found significant higher values of egg weight, albumen - and yolk weight in quails from IInd and IIIrd experimental groups. There was a tendency to increase the egg shell weight and egg shell thickness in all treated groups in comparison to the control group. The usе of VemoHerb T did not aggravate the sensor properties of the quails’ eggs.

    Full Text Available One hundred and eighty 7-week-old laying quail were fed various diets over a 12-week period. The diets included a control diet (without essential oil mixture (EOM or antibiotics (ANTs, a basal diet including EOM (24 mg/kg feed, and a basal diet including an ANT (avilamycin, 10 mg/kg feed. Each treatment comprised 4 replications with 4 cages (15 quail per cage, amounting to 60 quail per treatment group. Diets (in mash form and water were provided for ad libitum consumption. EOM consisted of 6 different essential oils derived from the following herbs: oregano (Origanum sp., laurel leaf (Laurus nobilis L., sage leaf (Salvia triloba L., myrtle leaf (Myrtus communis, fennel seeds (Foeniculum vulgare, and citrus peel (Citrus sp.. In comparison with the control diet, adding supplements such as EOM and ANTs to the basal diet increased egg production in quail (P<0.001. However, egg production was similar between EOM and ANT treatment groups. Moreover, there were no differences between the treatment groups with regard to egg weight. Feed intake was not affected by EOM or ANT supplementation, whereas feed conversion ratio was significantly improved by EOM and ANT supplementation. Thus, we concluded that EOM has beneficial effects as a dietary supplement on egg production and feed conversion ratio.

    The present functional neuroimaging study focuses on the iconography of mourning. A culture-specific pattern of body postures of mourning individuals, mostly suggesting withdrawal, emerged from a survey of visual material. When used in different combinations in stylized drawings in our neuroimaging study, this material activated cortical areas commonly seen in studies of social cognition (temporo-parietal junction, superior temporal gyrus, and inferior temporal lobe), empathy for pain (somatosensory cortex), and loss (precuneus, middle/posterior cingular gyrus). This pattern of activation developed over time. While in the early phases of exposure lower association areas, such as the extrastriate body area, were active, in the late phases activation in parietal and temporal association areas and the prefrontal cortex was more prominent. These findings are consistent with the conventional and contextual character of iconographic material, and further differentiate it from emotionally negatively valenced and high-arousing stimuli. In future studies, this neuroimaging assay may be useful in characterizing interpretive appraisal of material of negative emotional valence. © The Author (2017).

    The objectives of this study were to determine the effect of selenium (Se) from Se-enriched kale sprout (Brassica oleracea var. alboglabra L.) on the performance and Se concentrations in tissues of growing Japanese quails. Two hundred quails were divided into five treatments. Each treatment consisted of four replicates and each replicate contained ten quails in a completely randomize design. The experiment was conducted for 5 weeks. The treatments were T1, control diet; T2, control diet plus 0.2 mg Se/kg from sodium selenite; T3, T4, and T5, control diet plus 0.2, 0.5, and 1.0 mg Se/kg from Se-enriched kale sprout. The results revealed that Se supplementation had no impact on feed intake, performance, and carcass characteristics of quails (p > 0.05). However, Se supplementation from both sodium selenite and Se-enriched kale sprout increased (p kale sprout. The results indicate that Se from Se-enriched kale sprout offers no advantage over Se from sodium selenite on tissue Se concentration.

    Full Text Available Quail egg production has experienced a steep rise in the last decade. Nutrition is the main factor affecting productive potential in the poultry industry, as appropriate nutritional management is necessary to ensure the maintenance of optimal physical conditions, growth and the production of high quality products. Meat and bone meal (MBM has often been used in the poultry industry as an alternative and cost-effective source of protein in partial replacement of corn and soybean meal. However, there have been no studies to date that have investigated the effect of dietary MBM on the performance of quail or on the costs of production in the starter phase. This is particularly important considering that this phase is characterized by large investments by producers, without immediate economic return. In this study, we investigated whether partial replacement of soybean meal (SBM by meat and bone meal (MBM in the diet of Japanese quail during the starter phase is a viable alternative that would maintain or improve their productive and economic performance. Our results show that the inclusion of MBM in the diet of quail reduces feeding costs by up to 6% without impairing productive performance.

    The Hawk-Dove game played between individuals in populations of finite dimension is analyzed by means of a stochastic model. We take into account both cases when all individuals in the population are either phenotypically homogeneous or heterogeneous. A strategy in the model is a gene representing the probability of playing the Hawk strategy. Individual interactions at the microscopic level are described by a genetic algorithm where evolution results from the interplay among selection, mutation, drift and cross-over of genes. We show that the behavioral patterns observed at the macroscopic level can be reproduced as the emergent result of individual interactions governed by the rules of the Hawk-Dove game at the microscopic level. We study how the results of the genetic algorithm compare with those obtained in evolutionary game theory, finding that, although genes continuously change both their presence and frequency in the population over time, the population average behavior always achieves stationarity and, when this happens, the final average strategy played in the population oscillates around the evolutionarily stable strategy in the homogeneous population case or the neutrally stable set in the heterogeneous population case.

    Following methods described by Louis Bureau (1911, 1913) in France,tabulations were made (1) of the ages at which captivity-reared bob-white quail (Colinus virginianus) dropped their juvenal remiges, and (2) the rates at which post-juvenal replxcement primaries grew. These were arranged so as to permit the determination of age in healthv birds from one to five months of age. The degree of individual variation was much greater than that found by Bureau, however. and limits accuracy in age determination after the 10th week..... The post-juvenal wing molt began on the birds' 28th day and ended when the quail were 146 to 154 days old.The post-juvenal body molt was found to take place largely between the 70th and 100th days. The juvenal rectrices were renewed from the 62nd to the 122nd days, the new feathers being as long as their longest coverts when the birds were 116 days old. The color of the tarsi varied from pink, at 32 days of age, to straw color at 60 days, and yellow-gray from 83 to 180 days. At six months, the color of the beak was identical with that of adults.....Unlike several other game bird species, the flexibility of the lower jaw was not an accurate index to age in bob-whites older than 11 weeks. Rigor mortis and freezing were found to hinder the testing of this criterion.

    The avian haemosporidian parasites (phylum Apicomplexa) are taxonomically diverse and cosmopolitan in distribution; infecting most bird families. Sources of concern are reports of clinical haemosporidian infections in birds kept as part of zoo and aviary collections. Recently, severe and acute mortality episodes have been reported in masked bobwhite quail (Colinus virginianus ridgwayi), an endangered subspecies from the American Southwest. Two hundred and five eggs of the captive flock held in Arivaca, Arizona, were hatched at a zoo in the American Southwest. Thirty four sub-adult or adult animals had lesions associated with tissue phases of hemoparasites, especially vasculitis, ventricular leiomyositis and ulcerative pododermatitis. Molecular techniques applied to blood collected from the zoo’s last twelve remaining animals resulted in the detection of a Plasmodium juxtanucleare-like and Haemoproteus sp. parasites. A Raven (Corvus corax), in a contiguous exhibit, was positive for the same Plasmodium juxtanucleare-like parasite, but remained asymptomatic for three years following detection. These findings indicate that other birds in the exhibit within the zoo premises could act as reservoirs. We conclude that haemosporidian infections could be a factor in the demise of the captive masked bobwhite quails housed at the zoo. We suggest that active surveillance for haemoporidian parasites should be incorporated as a precaution to ex-situ conservation efforts of susceptible endangered species. PMID:21726940

    Full Text Available Ornithobacterium rhinotracheale (ORT is a respiratory pathogen which has been isolated throughout the world from numerous bird species. The present study was designed to isolate and characterize the ORT from domestic turkeys, quails and pigeons. For this purpose, 250 samples from each bird species (turkey, quail and pigeon with or without respiratory signs were tested by taking of tracheal swabs. In addition, respiratory tissue samples (tracheal and lung, from 250 slaughtered turkeys, 50 slaughtered quails and 100dead pigeons were also subjected to culture for ORT as tracheal swabs. Respiratory tissues were also tested for bacterial DNA by using polymerase chain reaction (PCR. In general, 30 isolates including 4 isolates from turkeys, 3 isolates from quails and 23 isolates from pigeons were identified as ORT by bacteriologicalmethod and then confirmed by PCR. Bacterial DNA was detected in 20%, 50% and 35% of respiratory tissues in turkeys, quails and pigeons respectively. Five ORT isolates from pigeon and all four isolates from turkey showed smaller colony size, while other isolates had larger colonies when cultured in blood agar. Fifty percent of the isolates with larger colony but none of the isolates with small colony size could agglutinate red blood cells (RBCs. All of the isolates were sensitive to danofloxacin and chloramphenicolwhile more than 90% of pigeon isolates were resistant to ampicillin. All of turkey and quail and 30% of pigeon isolates were resistant to tetracycline. Our ORT isolates showed high identity (98%- 100% insequence of 16S rRNA gene to related data in GeneBank.

    Full Text Available In the first experiment, the chemical composition, apparent metabolizable energy (AME, AME corrected for nitrogen (AMEn, true metabolizable energy (TME, TME corrected for nitrogen (TMEn values of the sweet almond meal were determined in adult Leghorn cockerels. The second experiment was performed to evaluate the effects of different levels of sweet almond meal at 0, 100, 200 and 300 g/kg on Japanese quail's growth performance, some blood metabolites, relative weight of different organs, meat quality and egg yolk cholesterol in a completely randomized design with 288 Japanese quails including 4 treatments, 4 replicates and 18 birds per replicate. The metabolizable energy values of sweet almond meal were following: AME = 3734, AMEn = 3648, TME = 3908, TMEn = 3746 kcal/kg as fed basis. Feed intake, feed conversion ratio and live weight gain and relative weight of different organs in the birds fed diets with different levels of the sweet almond meal were not statistically different from control. A sweet almond meal at 300 g/kg level showed the lower serum total cholesterol and low-density lipoprotein (P < 0.05 compared to control and 100 g/kg sweet almond meal. Dietary treatments had no significant effect on the total cholesterol content of quail's eggs. Malondialdehyde concentration in breast meat samples after 40 days freezing decreased, whereas the level of sweet almond meal increased (P < 0.01. In general, a sweet almond meal without any adverse effect on growth performance is a good source of energy and protein and can be used up to 300 g/kg of the Japanese quail diets.

    Northern bobwhite (Colinus virginianus) and scaled quail (Callipepla squamata) have experienced chronic declines within the Rolling Plains ecoregion of Texas. Parasitic infection, which has long been dismissed as a problem in quail, has not been studied thoroughly until recently. A total of 219 northern bobwhite and 101 scaled quail from Mitchell County, Texas were captured and donated from 2014 to 2015, and examined for eyeworm (Oxyspirura petrowi) and caecal worm (Aulonocephalus pennula) infections. In 2014, bobwhites averaged 19.6 ± 1.8 eyeworms and 98.6 ± 8.2 caecal worms, and 23.5 ± 2.1 eyeworms and 129.9 ± 10.7 caecal worms in 2015. Scaled quail averaged 4.8 ± 1.0 eyeworms and 50 ± 6.8 caecal worms in 2014, and 5.7 ± 1.3 eyeworms and 38.1 ± 7.1 caecal worms in 2015. This study expands the knowledge of parasitic infection in quail inhabiting the Rolling Plains of Texas. A significant difference was documented in O. petrowi infection between species but there was no significant difference in A. pennula between quail species. No significant difference was detected in parasite infection between the sexes of both northern bobwhite and scaled quail. This study also documented the highest reported O. petrowi infection in both species of quail. Additional research is needed on the life history and infection dynamics of O. petrowi and A. pennula infections to determine if there are individual- and/or population-level implications due to parasitic infection.

  12. Modified saponification and HPLC methods for analyzing carotenoids from the retina of quail: implications for its use as a nonprimate model species.

    To investigate carotenoid content in the retina of Japanese quail (Coturnix japonica), for comparison with carotenoids in human retina, and to assess the effects of different saponification procedures on the recovery of quail retinal carotenoids. Extracted retinal carotenoids were saponified with methods adapted from recent studies, then identified and quantified with reverse-phase high-performance liquid chromatography (HPLC). To assess the effects of saponification conditions on carotenoid recovery from quail retina, we varied base concentration and the total time of saponification across a wide range and again used HPLC to compare carotenoid concentrations among conditions. Astaxanthin and galloxanthin were the dominant carotenoids recovered in the quail retina, along with smaller amounts of five other carotenoids (lutein, zeaxanthin, 3'-epilutein, epsilon-carotene, and an unidentified carotenoid). Astaxanthin was sensitive to saponification conditions; recovery was poor with strong bases (0.2 and 0.5 M KOH) and best with weak bases (0.01 and 0.2 M KOH). In contrast, xanthophyll carotenoids (galloxanthin, zeaxanthin, lutein, 3'-epilutein, and the unknown) were best recovered with strong base after 6 hours of saponification at room temperature. The recovery of epsilon-carotene was not affected by saponification conditions. Separate chemical hydrolysis procedures--using a strong base to recover xanthophylls and a weak base to recover astaxanthin--should be used for maximizing recovery of quail retinal carotenoids. Because the dominant carotenoids in quail retina are absent in human retina, and because of their different packaging (e.g., esterified in oil droplets) and light-absorbance properties compared with xanthophylls in the human eye, use of the quail as a model organism for studying human retinal carotenoids should be approached with caution.

  13. DDE increased the toxicity of parathion to coturnix quail

    1977-01-01

    Adult male Japanese quail (Coturnix coturnix) were exposed to DDE or chlordane in the diet and subsequently dosed with parathion or paraoxon. Pretreatment with 5 or 50 ppm DDE in the diet for 12 weeks resulted in increased cholinesterase (ChE) activity in plasma, but not in the brain. Dietary concentrations of 5 and 50 ppm DDE caused increased susceptibility of quail that were challenged with parathion or paraoxon. The increased mortality resulting from DDE pretreatment was reflected in brain ChE inhibition. The synergistic action of DDE was apparent after 3 days of exposure to 50 ppm DDE and 1 week of exposure to 5 ppm DDE. Birds exposed for 3 weeks to 5 or 50 ppm DDE retained their DDE-potentiated sensitivity to parathion after 2 weeks on clean diet. Chlordane pretreatment resulted in decreased susceptibility (antagonism) to parathion, but not to paraoxon dosage. Implications of differing responses in ChE and mortality among controls, DDE-, and chlordane-pretreated birds after parathion or paraoxon dosage are discussed.

    Full Text Available This experiment was conducted to analyze the performance and carcass characteristics of European quail fed agroindustry residue of guava in substitution of corn. 140 birds were used, distributed in a completely randomized design. The treatments consisted of a control diet and four diets with levels of guava waste inclusion (2.5, 5.0, 7.5 and 10.0% to a diet based on corn and soybean meal. There were no significant differences (P> 0.05 for the variables: weight gain, feed intake, feed conversion, feed efficiency, weight and carcass yield and prime cuts (breast, drumstick and thigh wings, back , neck, head, feet and foodstuffs organs (heart, liver and gizzard. The guava waste can be used as alternative ingredient in the diets of European quail in the period of 16-38 days of age, up to the level of 10% inclusion without depressing the performance and yield of poultry carcasses.

    This experiment was conducted to evaluate the effects of adding medicinal plants to Japanese quail diet on their performance and some metabolic functions. Four hundred, one day old, unsexed Japanese quails were used in this study. Quails were divided equally into four groups of 100 birds each according to medicinal plant additives. Group one was control (without additives, and the other groups contained 0.3% from anise (group 2), chamomile (group 3) and ginger (group 4). The end of the experiment was terminated when birds were 6 weeks old. Body weight, feed intake, some organs weight and some blood parameters were measured.The results indicated that addition of medicinal plants (anise, chamomile and ginger) improved growth rate, carcass and the relative weights of spleen, ovary and testis. Also, significant increases were observed in RBC, WBC, Hb, PCV, total protein and globulin. There was reduction in cholesterol in treated groups as compared to the control.The present results confirmed the beneficial effects of dietary medicinal plants (anise, chamomile and ginger) to improve the health condition as well as the productive and physiological characteristics of quails

    This report provides baseline environmental information for the property identified for possible expansion of the Yakima Firing Center. Results from this work provide general descriptions of the animals and major plant communities present. A vegetation map derived from a combination of on-site surveillance and remotely sensed imagery is provided as part of this report. Twenty-seven wildlife species of special interest (protected, sensitive, furbearer, game animal, etc.), and waterfowl, were observed on the proposed expansion area. Bird censuses revealed 13 raptorial species (including four of special interest: bald eagle, golden eagle, osprey, and prairie falcon); five upland game bird species (sage grouse, California quail, chukar, gray partridge, and ring-necked pheasant); common loons (a species proposed for state listing as threatened); and five other species of special interest (sage thrasher, loggerhead shrike, mourning dove, sage sparrow, and long-billed curlew). Estimates of waterfowl abundance are included for the Priest Rapids Pool of the Columbia River. Six small mammal species were captured during this study; one, the sagebrush vole, is a species of special interest. Two large animal species, mule deer and elk, were noted on the site. Five species of furbearing animals were observed (coyote, beaver, raccoon, mink, and striped skunk). Four species of reptiles and one amphibian were noted. Fisheries surveys were conducted to document the presence of gamefish, and sensitive-classified fish and aquatic invertebrates. Rainbow trout were the only fish collected within the boundaries of the proposed northern expansion area. 22 refs., 10 figs., 4 tabs.

    2015-06-01

    Full Text Available A comparative histomorphological study was conducted on thymus of broiler chicken, duck and quail. The thymus of all three species of post-hatch (adult birds showed a thin connective tissue capsule. However, fine septa originating from the capsule divided the organ into incomplete but distinct lobules in chicken, whereas lobules were ill defined in both quail and duck. Each lobule, in turn, was composed of a peripheral cortex, densely studded with lymphocytes and a central medulla that was enriched with epithelial reticular cells. So, the cortex appeared more basophilic than that of medulla. But the concentration of lymphocyte, an immune competent cell was highest in chicken followed by duck and quail. Hassall’s corpuscles like structures were found inside the medulla as pale stained diffuse body. General histo-architecture was almost similar in all the birds.

    Researches of features of lipid composition, functioning of the system of antioxidant defense, maintenance of lipid peroxidation products in the quail's pancreas on the early postnatal ontogenesis stages are conducted for actions of nitrates and feeding with amaranth's seeds in mixed fodder. The arrival of nitrates in the organism of quails results in the decline of general lipids maintenance and nonetherified fat acids in the pancreas. Using of amaranth's seeds in mixed fodder on the background of the nitrate loading results in the increase of activity of the enzimes system of antioxidant defence, the growth of general lipid level in the quail's pancreas. Thus in correlation with separate classes of lipid maintenance of cholesterol goes down for certain, whereas the maintenance of triacylglycerols and ethers of cholesterol rises. The results obtained in the researches show the ability of amaranth's seeds to avert oxidative stress in quail's pancreas under nitrates influence.

    1. The effects of ascorbic acid (L-ascorbic acid) and melatonin supplementation on performance, carcase characteristics, malondialdehyde (MDA) as lipid peroxidation indicator, ascorbic acid, retinol, tocopherol and mineral status in the Japanese quail (Coturnix coturnix japonica) exposed to high ambient temperature were evaluated. 2. Two hundred and forty Japanese quails (10 d old) were randomly assigned to 8 treatment groups consisting of 10 replicates of three birds each. The birds were kept in a temperature-controlled room at 22 degrees C (Thermoneutral, TN groups) or 34 degrees C (for 8 h/d; 09:00 to 17:00 h; Heat stress, HS groups). Birds in both TN and HS were fed either a basal (control) diet or the basal diet supplemented with 250 mg of L-ascorbic acid/kg of diet (Ascorbic acid group), 40 mg of melatonin/kg of diet (Melatonin group) or both (Ascorbic acid + Melatonin group). 3. Supplementing heat-stressed quails with ascorbic acid and melatonin improved performance compared with the control group. Effects generally were greatest in quails supplemented with both ascorbic acid and melatonin. 4. Although supplementation did not consistently restore the concentrations of serum ascorbic acid, retinol and tocopherol to those of TN groups, these concentrations increased significantly with supplementation. Furthermore, serum and liver MDA and serum cholesterol and glucose concentrations were lower in the supplemented groups than in the heat-stressed controls. 5. Within each environment, excretion of Ca, P, Mg, Zn, Fe and Cr were lowest in the combination group and, in all cases, highest in the HS group. Interactions between diet and temperature were detected for live weight gain, cold carcase weight, MDA, ascorbic acid, tocopherol concentrations and excretion of zinc. 6. The results of the study indicate that ascorbic acid and melatonin supplementation attenuate the decline in performance and antioxidant and mineral status caused by heat stress and such

    Full Text Available Death and mourning that follows it are experiences that occurs in everyone`s life at one time. There are unavoidable, painful, sad experiences even for adults who are able to manage their own emotions, and evenmore for children who, at least in early childhood and elementary school aren't able to understand on their own what it's happening in that moment, and how to manage their sadness and live the mourning period properly. Due to the fact that children are not yet fully developed cognitively, cannot understand on their own the concept of death. At that age, death seems for them not to be permanent. Children believe that death is a reversible process that the person in their family is temporarily left and they will return at any moment, and they will wait and ask for that moment long after the actual death, if lacked of any other information. Moreover, children think that death is avoidable, since - at that age, self-centeredness is somehow a characteristic of their personality and death hasn't affected their own person; therefore, when death occurs in their family, their reality will be brutally shaken and they will be very disoriented. Also, in early childhood, kids have a symbolic, magical perspective about death; they imagine it as a devil, a monster or a black lady with a scythe and many other images, far from a realistic perspective. Considering this aspects, it is very important that a realistic, honest, adapted to their age perspective of death when it affects their family. Unfortunately, in many cultures, death is still a taboo. It still exists the belief of overprotecting children from suffering by hiding the death of a close family member, lying them and taking them far away so that they cannot see the dead person. But actually, by practicing this, parents, teachers and persons around the children only make him be more disoriented and suffer more by not knowing what happened with the person they love. As a parent or teacher, it is

    The objective of the present study was to estimate heritabilities as well as genetic and phenotypic correlations for egg weight, specific gravity, shape index, shell ratio, egg shell strength, egg length, egg width and shell weight in Japanese quail eggs. External egg quality traits were measured on 5864 eggs of 934 female quails from a dam line selected for two generations. Within the Bayesian framework, using Gibbs Sampling algorithm, a multivariate animal model was applied to estimate heritabilities and genetic correlations for external egg quality traits. The heritability estimates for external egg quality traits were moderate to high and ranged from 0.29 to 0.81. The heritability estimates for egg and shell weight of 0.81 and 0.76 were fairly high. The genetic and phenotypic correlations between egg shell strength with specific gravity, shell ratio and shell weight ranging from 0.55 to 0.79 were relatively high. It can be concluded that it is possible to determine egg shell quality using the egg specific gravity values utilizing its high heritability and fairly high positive correlation with most of the egg shell quality traits. As a result, egg specific gravity may be the choice of selection criterion rather than other external egg traits for genetic improvement of egg shell quality in Japanese quails.

    this investigation aims to study the possibility of using gamma iraadiation or sodium tripolyphoshate (STPP) for increasing shelf-life of quail carcasses during cold storage. The quail carcasses were gamma irradiated at 4, 6 and 8 kGy or soaked in 3% STPP. The effect of these treatments on the organoleptic, microbiological aspects and chemical properties of samples under investigation were evaluated during cold storage (4± 1C degree). The results indicated that, the chemical compositions of samples did not alter by gamma irradiation or soaking in STPP. Futhermore, treatment had no deterious effects on the organoleptic properties of quail samples. Meanwhile, irradiation of samples at doses of 4, 6 and 8 kGy or soaking in STPP greatly reduced its microbial count and prolonged the shelf-life for 15,21,24 and 9 days at 4 ± 1 Cdegree in comparison with 6 days for control samples. Moreover, the acid value (A.V), peroxide value (P.V) and thiobarbituric acid (TBA) value were increased after irradiation, while total volatile basic nitrogen (TVBN) content had no real change by this treatment. On the other hand, soakking in STPP treatment decreased these values and gradual increases were observed during cold storage

    Poultry production is considered one of the prospective opportunities to accomplish sustainable and quick production of superior protein to challenge the growing mandate for animal protein. Therefore, this study was aimed to explore the difference on growth performance, carcass traits, meat quality and amino acid profile of different Japanese quails strains. A total of 480 quail chicks of four different plumage colors (120 of each white, golden, gray and brown) were collected after hatching. At 6 week of age, birds were stunned and decapitated to determine the physical meat quality, thiobarbituric acid reactive substances and amino acid profile. White quails had the highest weight of slaughter, carcass, dressing, carcass yield, liver, gizzard, heart and spleen (197.27 g, 169.27 g, 91%, 82%, 6.63 g, 6.53 g, 2.27 g and 0.40 g, respectively). Also, they had the highest Ph U , lightness, yellowness and water holding capacity with the lowest level of redness, cooking losses and thiobarbituric acid in pectoral (6.28, 46.40, 12,46, 22.17, 9.20, 19.21 and 0.44, respectively) and thigh muscles (6.37, 42.30, 11.51, 26.01, 10.12 and 0.93, respectively). Moreover, they possessed the highest level of all essential (11.68 and 10.16 g/100 g protein in pectoral and thigh muscles, respectively) and non essential amino acids (13.27 and 12.54 g/100 g protein in pectoral and thigh muscles, respectively). Therefore, the current study revealed that white quails had the heaviest body weight with the best carcass traits and meat quality.

    The current study was conducted to evaluate the effect of adding some probiotics into diets of Japanese quails on productive and reproductive performance, blood constituents, immune response and intestinal wall thickness. A total number of 500 one day old, unsexed Japanese quail chicks were used. Five experimental groups were assigned in the present study, where the 1st group (G1) was provided with protexin at 5 g/litre (5 days weekly). The 2nd group (G2) contained medi stress of 0.75 g/litre (5 days weekly), the 3rd group (G3) was fed a basal diet contained bioaction at 5g/kg, the 4th group (G4) involved a basal diet with active dried yeast (Saccharomyces cerevisiae) at 0.1 g/kg daily and group 5 were fed the basal diet without probiotics supplementation (control). The results showed that the average body weight, egg production and egg weight were significantly increased due to adding probiotics and 0.1g/kg yeast into diets. Feed conversion ratio and mortality were improved significantly and the most improvement was recorded at 1.0% yeast and protexin. Similar improvement was recorded for hatch ability and hatching weight. There were reductions in intestinal wall thickness due to adding 0.1 g/kg yeast or protexin. The values of HI titer against sheep RBCs were increased significantly as compared to the control, which may lead to an enhancement of immune response of Japanese quails. Blood protein, globulin and FSH hormone were increased significantly. In conclusion, adding some probiotics into diets of Japanese quails improved productive, reproductive performance, blood constituents, immune response and intestinal wall thickness.

    This is a study using the Heideggerian theoretical-phenomenological approach, which sought to understand the significances of the life experience for the long-lived elderly person in the process of death/dying and mourning. It was conducted in 2009 with 16 long-lived senior citizens of both genders who were aged between 80 and 90, members of a community center for the elderly located in a suburban neighborhood of the city of Salvador in the state of Bahia, Brazil. The results showed that the long-lived elderly person experiences the mourning status process when relatives and friends become ill and die. Furthermore, they gave ambiguous reports with respect to the fear of death. With the attributed significances, it was possible to arrive at the unit of significance, namely the authenticity and lack of authenticity of the individual regarding imminent death. The conclusion reached is that long-lived elderly individuals faced with the process of death/dying and mourning is apparent or concealed in accordance with the moment they are experiencing and the opportunities that present themselves, in other words, it is greatly influenced by their past.

    Mosquitoes in the Culex pipiens complex are competent vectors of West Nile virus (WNV; family Flaviviridae, genus Flavivirus) in the laboratory, and field-collected mosquitoes have tested positive for the virus in California and elsewhere. A better understanding of Cx. pipiens complex blood-feeding patterns will help define the threat that these mosquitoes pose to human health and their role in WNV amplification in northern California. We collected blood-engorged Cx. pipiens complex mosquitoes from resting sites near and away from human habitation in Sacramento and Yolo Counties. Cytochrome c oxidase 1 gene sequences were used to identify the vertebrate species from which blood meals were taken. Of 330 engorged mosquitoes collected at 28 sites from June through August 2007 and May through August 2008, >99% fed on an avian host. Three mosquitoes contained bovine blood and none had fed on a human. American Robins (Turdus migratorius) were bitten most often, and the proportion of American Robin blood meals increased significantly over the summer. Other important avian hosts included House Finches (Carpodacus mexicanus), Barn Swallows (Hirundo rustica), Western Meadowlarks (Sturnella neglecta), and Mourning Doves (Zenaida macroura). In rural areas, Barn Swallows, Brewer's Blackbirds (Euphagus cyanocephalus), and House Sparrows (Passer domesticus) were frequent hosts. In settings near human habitation, Mourning Doves and Western Meadowlarks were common hosts. Our data indicate that in north central California mosquitoes in the Cx. pipiens complex may be more important as epiornitic than epidemic vectors of WNV.

    The aim was to determine the chemical composition of solar dried blood and rumen content (DBRC) and further ascertain the concentration at which DBRC could be included in Japanese quail diets without any adverse effect on its performance. Feeding trial on the effect of DBRC on performance of Japanese quails was studied up to 5 weeks. 252 numbers of day old (Nandanam Type III breed) Japanese quails were purchased from Poultry Research Station, Madhavaram and divided into 7 batches (control+ six treatments) each consisting of 36 birds. The DBRC was included at 0%, 5%, 10%, 15%, 20%, 25% and 30% in diets as control, treatment-1 (T1), treatment-2 (T2), treatment-3 (T3), treatment-4 (T4), treatment-5 (T5) and treatment-6 (T6) respectively in a completely randomized design to replace soybean meal in Japanese quail feed. The birds were provided with ad-labidum feed and drinking water ad-libitum during the entire experimental period. The crude protein (CP), crude fiber (CF), ether extract (EE) and ash contents of DBRC were 35.87%, 17.40%, 3.6% and 12.6%, respectively. The amount of essential amino acids and non-essential amino acid content were found to be 12.98 and 4.87 (g/100 g of feed) respectively in DBRC feed. Result showed that all birds fed DBRC diets performed better than the control group. Mortality was unaffected by dietary treatments. There was a significant difference (p<0.01) observed in weight gain in treatment groups compared to the control. Up to 30% DBRC could be incorporated in the diets of Japanese quails without any adverse effects on its performance.

    Full Text Available The current study was conducted to investigate the effect of short-term divergent selection on the shape growth curve in different lines of Japanese quail. The Quail lines utilized in this study were two divergently selected for high (HW and low (LW 4-wk body weight during 7 generation and also a control line (C. The Richard function parameters were used to describe growth curves of different lines. The weight at hatch was approximately similar among lines (8.08 g, 7.55 g and 8.76 g for HW, LW and C line respectively. The results of current study indicated that the selected lines (HW & LW were immediately diverged from the C line after hatch. Sexes within each line had no difference in average growth rate, age and body weight at inflection point and adult body weight. However significant differences were found in the growth curve parameters among lines. The results of current study indicated that short term divergent selection for 4-wk BW in Japanese quail can change the growth pattern and the carcass compartments of the selected birds. Therefore to avoid undesirable side effects due to selection in Japanese quails it is recommended to consider the growth pattern changes of the selected birds in the breeding programs

    Five groups of 30 male Japanese quail, each 7-w-old, were fed diets containing 0, 1, 3, 5, or 10% (w/w) of dehulled H dolosum seed. Half of the birds from the each group were killed at 6 and 24 w after beginning of the trial. At the end of 6th w, neither mortality nor clinical sign occurred in test groups. In the 5 and 10% inclusion levels, mild to moderate hepatic injury was detected as evidenced by mild karyomegaly, moderate fatty change, focal or portal fibrosis, bile duct hyperplasie, and ovalocyte proliferation along with lower serum protein and albumin levels. By the termination of the experiment (24 w), 5 birds died in the 10% dosed group. Hepatic cirrhosis was the most prominent finding in the 5 and 10% group; at these levels, serum protein and albumin values decreased significanty while billuribin and ALP levels increased. Based on relative weights and histological evaluations, testicularatrophywasdosedependent. These results partly affirm earlier studies that the quail is highly resistant to the toxic effects of H dolosumseed. However, the resistance to H dolosum is less than Senecio Jacobae and Crotalaria spectabilis when considering tissue injury.

    Cadmium was fed to young Japanese quail, at a level of 75 mg. per kg. of diet, from hatching to 4 weeks of age. Cadmium produced gross, microscopic, and ultrastructural lesions in the proximal small intestine of these quail, similar to those occurring in human malabsorption syndromes, celiac disease, nontropical sprue, and tropical sprue. The small intestines of the quail were dilated and thin walled. Villi were short and thick and had a dense cellular infiltrate in the lamina propria. The striated border was thin but stained for neutral mucopolysaccharides, as did the normal border. Some villi were covered with stratified epithelial cells. Hypertrophy and hyperplasia of goblet were seen, but the mucin stained for weakly acidic mucopolysaccharides, as did the normal cells. At the ultrastructural level, microvilli of both absorptive and goblet cells were markedly shortened, particularly near the tips of the villi. Absorptive cells were atrophic, and there was s diminution of the usual cellular organelles. Granular cisternae were long and tortuous, mitochondria were dense and small, and large lysosome-like bodies and large lipid droplets accumulated in the cytoplasm, but there was a decrease in the normal small, pale and dark lipid droplets. The cellular infiltrate of the lamina propria included groups of plasma cells with dilated cisternae. There were large, irregular, electron-dense bodies in the endothelium of large veins and degeneration of some nerve plexuses in the muscularis propria. 31 references, 21 figures.

    Full Text Available Aim: The growth promoting effect of the blue-green filamentous alga Spirulina platensis (SP was observed on meat type Japanese quail with antibiotic growth promoter alternative and immune enhancing power. Materials and Methods: This study was conducted on 180 Japanese quail chicks for 4 weeks to find out the effect of diet type (vegetarian protein diet [VPD] and fish meal protein diet [FMPD]- Spirulina dose interaction (1 or 2 g/kg diet on growth perfor-mance, gut microbiota, and sensory meat quality of growing Japanese quails (1-5 weeks old. Results: Data revealed improvement (p<0.05 of weight gain, feed conversion ratio and European efficiency index due to 1, 2 g (SP/kg VPD, and 2 g (SP/kg FMPD, respectively. There was a significant decrease of ileum mean pH value by 1 g (SP/kg VPD. Concerning gut microbiota, there was a trend toward an increase in Lactobacilli count in both 1; 2 g (SP/kg VPD and 2 g (SP/kg FMPD. It was concluded that 1 or 2 g (SP/kg vegetarian diet may enhance parameters of performance without obvious effect on both meat quality and gut microbiota. Moreover, 1 and/or 2 g (SP may not be invited to share fish meal based diet for growing Japanese quails. Conclusion: Using of SP will support the profitable production of Japanese quails fed vegetable protein diet.

    The authors conducted in-depth interviews with 38 mothers and fathers who had lost an infant. The focus of the interview was aggression and guilt during mourning work. The participants felt strong shame after separation. Phenomena such as strong irrational guilt, aggression, and hesitation toward others were similar to feelings typical of the paranoid-schizoid position. However, mourners did not lose their sense of reality, continued to do daily chores, and kept taking care of others. In this period, mourners were in disintegration, similar to individuals in the paranoid-schizoid position. Shame may be the feeling in the residue of the paranoid-schizoid position, through which they felt persecuted by others, their partner, relatives, and God. Their aggression was strong, but generally their aggression and impulses came to be used constructively and they progressed to integration. At the moment their children died, mourners fluctuated between disintegration and integration. After a certain interval, fluctuation subsided or integration predominated. In times of fluctuation, containers were very important for mourners to move toward integration. Participants reported changes in their lifestyle after the loss of a child. Mental health professionals should view aggressive impulses among such people during mourning not as an obstacle, but rather as a means to move toward integration. The authors speculate that a psychotherapist can serve as a container for mourners.

    Full Text Available Co-administration of vitamin E and selenium has positive effects on growth performance of avian species, but their effect is not fully elicited in the Japanese quail. Also, controversial reports exist for the effect of vitamin E and selenium on avian performance. This study was designed to investigate the effect of different levels of selenium (0, 0.2 and 0.4 mg/kg and vitamin E (0, 150 and 300 mg/kg in the diet of the Japanese quail. Birds received mesh diet from the start of the study, then selenium and vitamin E were added on day 17. At the end of the study, after food deprivation for 6 hours, Japanese quail (1 male and 1 female were selected and blood samples collected for biochemical investigations and determination of glucose, albumin, total protein, cholesterol, triglyceride, HDL and LDL levels. There was significant decrease in cholesterol, glucose, and triglyceride levels and significant decrease in albumin and total protein levels on day 35 (p

    Eurasian collared doves (Streptopelia decaocto) have expanded their range across the United States since their introduction several decades ago. Recent mortality events in Eurasian collared doves in Arizona and Montana, USA, during the winter of 2009-2010 were the result of pigeon paramyxovirus (PPMV), a novel disease agent. The first instance of mortality by this emerging infectious disease in this species occurred in Florida in 2001 with subsequent disease events in 2006 and 2008. Full diagnostic necropsies were performed on carcasses from the three states. PPMV was identified by RT-PCR and virus isolation and was sequenced to the VIb genotype of avian paramyxovirus-1 (APMV). Other APMVs are common in a variety of free-ranging birds, but concern is warranted because of the potential for commingling of this species with native birds, virus evolution, and threats to domestic poultry. Improved surveillance for wildlife mortality events and efforts to prevent introduction of non-native animals could reduce the threat of introducing new pathogens.

    1995-05-01

    Divergent lines of Japanese quail Coturnix japonica showing high (HSR) or low (LSR) levels of social reinstatement (SR) behaviour (as measured in a treadmill apparatus) have been developed. However, it was not known if selection had influenced social reinstatement tendencies in a general or a species-specific fashion. Therefore, the present study compared the SR behaviour of quail chicks of the HSR and LSR lines and of a Control line when the goal box of the treadmill was empty or when it contained small, same-species groups of either Japanese quail, domestic fowl or Guinea fowl chicks. The results clearly demonstrated that the SR behaviour of Japanese quail chicks is species-specific and that this specificity has not been influenced during genetic selection, over sixteen generations, of the HSR and LSR lines. The HSR chicks showed more locomotor activity in the treadmill than did those of the other lines regardless of the nature of the goal-box stimulus. The results are discussed in terms of general activity, underlying fearfulness and social motivation.

    Full Text Available ABSTRACT These experiments were performed to determine the chemical composition, coefficients of nutrient and energy metabolizability, amino acid composition, and cytotoxicity of different castor oil meals subjected to different detoxification processes and added to the diet of Japanese quails. In the trial, 180 46-d-old female Japanese quails were distributed according to a completely randomized design into five treatments and with replicates of six bird each. The treatments consisted of following detoxification methods of castor oil meal: Castor oil meal A (CMA - recovery in alcohol at 80 °C for 20 minutes and drying at 80 °C; castor oil meal B (CMB and C (CMC - recovery in alcohol at 80 °C for 6 minutes, neutralization with 5% NaOH, and drying under direct sunlight sun for two days (CMB or pelleted (CMC; castor oil meal D (CMD - recovery in alcohol at 110 °C for 15 minutes and drying at 110 °C. Castor oil meal was added replacing 20% of the reference diet. There was slight chemical composition variation (1.21% in crude protein, 6% in dry matter, 2.2% in ether extract and 64 kcal/kg in gross energy among the castor oil meals submitted to the different treatments. The castor oil meal submitted to treatment C showed the highest amino acid values. In the cytotoxicity test, treatment D presented lower ricin activity. Castor oil meals A, C, and D may be included in Japanese quail diets; however, castor oil meal D is recommended due to the simplicity its industrial process, its low toxicity, and metabolizability coefficients obtained.

    This study aimed to determine the effectiveness of Se from hydroponically produced Se-enriched kale sprout (HPSeKS) on productive performance, egg quality, and Se concentrations in egg and tissue of laying quails. Two-hundred quails, 63 days of age, were divided into four groups. Each group consisted of five replicates and each replicate had ten birds, according to a completely randomized design. The experiment lasted for 6 weeks. The dietary treatments were T1 (control diet), T2 (control diet plus 0.2 mg Se/kg from sodium selenite), T3 (control diet plus 0.2 mg Se/kg from Se-enriched yeast), T4 (control diet plus 0.2 mg Se/kg from HPSeKS). The findings revealed that productive performance and egg quality of quails were not altered (p > 0.05) by Se sources. Whole egg Se concentrations of quails fed Se from HPSeKS and Se-enriched yeast were higher (p  0.05), but higher (p < 0.05) than that of quails fed Se from sodium selenite. The results reveal that Se from HPSeKS did not change the performance and egg quality of quails. The effectiveness of Se from HPSeKS was comparable to that of Se-enriched yeast, which was higher than that of Se from sodium selenite.

    This experiment was conducted to evaluate the effect of adding Eucalyptus globules Egypt to Japanese quail diet on performance and some metabolic functions and immunity. Four hundred,one day old, unsexed japanese quails were used in this study. Quails were divided equally into four groups containing 100 birds in each. Each group contained 4 replicates of 25 birds. Group one was supplemented with 1% Egypt in basal diet, group two was supplemented with 2% Egypt in basal diet, group three was used as negative control (-ve)without any addition of antibiotic in diet or water, while group four represented the positive control (+ ve) by addition antibiotics (0.5 g neomycin sulphate +0.5 g oxytetracyclin) in drinking water for 5 days post hatching. The experimented diet contained 3200 Kcal ME/kg and 24% crude proteins. The end of the experiment was terminated when birds were 6 weeks old. Body weight, mortality, some organs weighs and some blood parameters were measured and some microbial population of small intestines was counted. Results indicated that the addition of Egypt led to significant increase in quails body weights, spleen, bursa and ovary and the measures of total proteins, globulins, haemagglutination inhibition (HI)and triiodothyronine (T3). Decrease in mortality ratio and less counts of microflora and salmonella of gut were also achieved as a result of diet camphor addition

    Full Text Available H9N2 avian influenza A viruses are endemic in poultry of many Eurasian countries and have caused repeated human infections in Asia since 1998. It has been also reported that H9N2 can cause high mortality in commercial broiler farms in Iran previously. However there was no report of H9N2 outbreak in any other species. In order to evaluate the pathogenicity of H9N2 virus in Japanese quail, 145 Japanese quail were randomly divided into 5 separate groups (116 quails in the treatment and 29 quails in the control groups. The experimental groups infected via oral rout, eye drop, intramuscular injection and spray method at the age of 32 days with 106.5 EID50/bird. The virus A/chicken/Iran/ZMT-101/98(H9N2 was kindly provided obtained from Razi vaccine& serum institute with EID50=108. The blood samples were experimented the day before use to show freedom from antibodies to influenza A and more specifically, the H9 subtype. The clinical signs and antibody titer of the infected chicks were also monitored. Five birds of each group were bled at 10 and 20 days post infection (DPI, and 20 birds of each group at 30 DPI were bled. The immune response to infection was measured by Haemmaglutination Inhibition (HI test using the H9N2 virus as antigen. Feed & water consumption were recorded on daily bases before and after inoculation. Body weight of each group was also recorded on weekly bases before and after inoculation. During the current study clinical signs such as sneezing, gasping, depression observed in challenged groups followed by decreasing in laying (1-17%. High HI antibody titers of AIV subtype H9 was seen in 10 DPI. The quails exhibited no decrease in food and water consumption and all quails were growing well and did not show any abnormality.

    Clothianidin (CTD) is a neonicotinoid developed in the 1990s as an insecticide having selective toxicity, but it was later found to cause reproductive abnormalities in rats through oxidative stress. There is an attempt to preserve endangered animals, including the Japanese crested ibis, in Japan. However, there is a concern that neonicotinoid affects the reproduction of this bird, since it is used in its habitat. CTD toxicity in the birds is poorly understood, so we investigated whether or not the daily oral administration of CTD has any deleterious effects on the reproductive functions of mature male quails as experimental animals. The animals were randomly divided into four groups of 6 or 7 quails each, treated orally with 0, 0.02, 1 or 50 mg CTD/kg body weight (Control, CTD0.02, CTD1 and CTD50). After that the males bred with untreated females to estimate the egg weights, and rates of fertilization and normal development, the testes, liver and spleen were examined histologically. Vacuolization and the number of germ cells having fragmented DNA in seminiferous tubules, and the number and size of vacuoles in hepatocytes increased dose-dependently. There were no significant differences in egg weights and fertilization rates between the groups, but some eggs of the CTD1 and CTD50 groups failed to develop, and embryonic length decreased dose-dependently. Thus, it was found that CTD affected the reproduction of the male quail through the fragmentation of germ cells and the inhibition or delay of embryonic development.

    The objective of this study was to investigate the effects of L-cysteine-coated iron oxide nanoparticles on reproductive performance in breeder quails. The five treatment diets consisted of (i) negative control diet not supplemented with iron, (ii) positive control diet supplemented with 60 mg/kg of Fe 3 O 4 and (iii) experimental diets supplemented with 0.6, 6 and 60 mg/kg of L-cysteine-coated iron oxide nanoparticles. A total of 100 seven-day-old quail chicks were weighed and randomly placed to five groups of five replicate cages. Four quails (one male and three females) were raised in each cage (50 × 15 × 17 cm). Egg production, feed consumption and egg weight were recorded daily and calculated on a hen per day basis. Egg components, fertility, hatchability and day-old chicks hatched from their eggs were measured at the end of the experiment. The percentage of egg production and egg mass of the 6 mg/kg Fe 3 O 4 -Cys NPs group were significantly higher than those of the control groups. Throughout the experimental period, the highest weekly egg weight was recorded for the 60 mg/kg Fe 3 O 4 -Cys NPs group. Fertility was improved by diet supplemented with iron, both FeSO 4 and Fe 3 O 4 -Cys NPs. The breeder fed Fe 3 O 4 -Cys NPs had the highest day-old chicks weight. The results of this study showed that Fe 3 O 4 nanoparticles that were coated by L-cysteine could improve availability and utilization of iron in diet. Finally, it was proposed that Fe 3 O 4 -Cys NPs could be used as feed additives in quails. © 2017 Blackwell Verlag GmbH.

    Full Text Available The aim of our study was to investigate effects of increased testosterone content in egg yolk on early behaviour of 1- and 2-day-old Japanese quail. Three different doses of testosterone (0.25; 2.5 and 25 ng, not exceeding a physiological range, were examined in three separate experiments. Testosterone propionate dissolved in 20 μl olive oil was injected into the yolk before the onset of incubation. Behaviour of newly hatched chicks was recorded in response to both a novel environment in the open-field test and manual restraining in the test of tonic immobility (TI. Behavioural consequences of embryonic exposure to elevated testosterone were observed in the open-field test in all three experiments which indicated inhibition of behavioural responses in hatchlings. Birds treated with testosterone in ovo displayed longer latency to leave the start square, decreased locomotor activity, enhanced defecation and lower number of distress calls as compared to control birds. In TI test, the influence of treatment was manifested at the highest concentration only. Hatchlings from testosterone treated eggs expressed longer duration of TI and required less attempts to induce TI in comparison with the control group. Our results demonstrated increased fearfulness of Japanese quail chicks hatched from eggs with experimentally elevated testosterone content. The effect is specific for a short period after hatching since previous studies reported stimulatory effect of yolk testosterone on behaviour of Japanese quail later in ontogeny.

    This study was conducted in two separate experiments. Experiment I was conducted to investigate the effects of hemp seed (HS) on meat quality traits, and experiment II was designed to determine egg fatty acid (FA) composition in Japanese quail (Coturnix coturnix japonica). In experiment I and experiment II treatments, groups were as follows: (i) control (not included HS0), (ii) 5% HS inclusion to diets, (iii) 10% HS inclusion to diets and (iv) 20% HS inclusion to diets. In experiment I, a total of 192 7-day-old-quail were fed with HS diets for 5 weeks, and end of the experiment I, a total of 64 quail (16 each) slaughtered and meat samples were analysed for meat colour, pH, cooking and thawing loss and FA composition. In experiment II, a total of 120 8-week-old laying quail were fed with experimental diets for 6 weeks and egg FA composition were determined. Breast meat cooking loss was significantly lower in 20% supplemented group (p egg samples were linearly increased with increasing the dietary HS ratio (p eggs (p egg yolk omega-3 FA content and decrease cooking loss of quail meats. © 2017 Blackwell Verlag GmbH.

    Understanding how past climatic oscillations have affected organismic evolution will help predict the impact that current climate change has on living organisms. The European turtle dove, Streptopelia turtur, is a warm-temperature adapted species and a long distance migrant that uses multiple flyways to move between Europe and Africa. Despite being abundant, it is categorized as vulnerable because of a long-term demographic decline. We studied the demographic history and population genetic structure of the European turtle dove using genomic data and mitochondrial DNA sequences from individuals sampled across Europe, and performing paleoclimatic niche modelling simulations. Overall our data suggest that this species is panmictic across Europe, and is not genetically structured across flyways. We found the genetic signatures of demographic fluctuations, inferring an effective population size (Ne) expansion that occurred between the late Pleistocene and early Holocene, followed by a decrease in the Ne that started between the mid Holocene and the present. Our niche modelling analyses suggest that the variations in the Ne are coincident with recent changes in the availability of suitable habitat. We argue that the European turtle dove is prone to undergo demographic fluctuations, a trait that makes it sensitive to anthropogenic impacts, especially when its numbers are decreasing. Also, considering the lack of genetic structure, we suggest all populations across Europe are equally relevant for conservation.

    Nanotechnology is extensively used in all parts today. Therefore, nano synthesis is also significant in all explored areas. The results of studies conducted have revealed that nanoparticle synthesis is performed by using both chemical and physical methods. It is well known that these syntheses are carried out at high charge, pressure and temperature in harsh environments. Therefore, this study investigated green synthesis method that sustains more mild conditions. In this study, quail egg yolk having high vitamin and protein content was prepared for green synthesis reaction and used for the synthesis of platinum nanoparticles in the reaction medium. Reaction situations were optimised as a function of pH, temperature, time and concentration by using quail egg yolk. The results showed that the highest platinum nanoparticles were synthesised at 20 °C and pH 6.0 for 4 h. Also, optimal concentration of metal ions was established as 0.5 mM. The synthesised platinum nanoparticles were characterised by using UV spectrum, X-ray diffraction and scanning electron microscope.

    Factorial correspondence analysis was performed on 341 quails from a F2 cross between two lines divergently selected on the duration of tonic immobility over 29 generations. Several fear- or stress-related traits were recorded, i.e. tonic immobility duration, number of inductions needed to induce tonic immobility, open-field behaviour (time spent walking, latency before first movement and number of defecations), asymmetry of tibia lengths and corticosterone concentration after restraint stress. Variables were categorised in classes and analysed by factorial correspondence analysis. The first axis was mostly described by open-field behaviour, and the second by tonic immobility traits (duration of tonic immobility and number of inductions), which showed that these behaviours were almost independent. No relationship was found between axes of the factorial correspondence analysis and corticosterone concentration or asymmetry of tibia lengths, showing that these variables reflected other characteristics of stress susceptibility than those described by tonic immobility and open-field behaviour. These results show that reaction to stress of quails is a multidimensional trait and cannot be summarised by one trait.

    Full Text Available The role of Defensive exclusion (Deactivation and Segregated Systems in the development of early relationships and related to subsequent manifestations of symptoms of eating disorders was assessed using the Adult Attachment Projective Picture System (AAP. Fifty-one DSM-IV diagnosed women with anorexia participated in the study. Anorexic patients were primarily classified as dismissing or unresolved. Quantitative and qualitative analyses of defensive exclusion were carried out. Results showed potential benefits of using the AAP defense exclusion coding system, in addition to the main attachment classifications, in order to better understand the developmental issues involved in anorexia. Discussion concerned the processes, such as pathological mourning, that may underlie the associations between dismissing and unresolved attachment and anorexia. Implications for developmental research and clinical nosology are discussed.

    A population approach was used to evaluate the pharmacokinetic parameters of 3 fluoroquinolones administered to Japanese quail (Coturnix coturnix japonica). Healthy adult quail (n = 50) were divided into 3 groups, each administered a separate intravenous and oral dose of the compounded drug: enrofloxacin at 10 mg/kg (n = 18; 9 male, 9 female), danofloxacin at 10 mg/kg (n = 12; 6 male, 6 female), and marbofloxacin at 5 mg/kg (n = 20; 10 male, 10 female). A fourth group was used as a control (n = 5). Enrofloxacin was metabolized extensively to ciprofloxacin, while no metabolites of either danofloxacin or marbofloxacin were detected. The volume of distribution was high, greater than 1 in all cases, and highest for danofloxacin, followed by enrofloxacin, then marbofloxacin. The total body clearance was higher in quail than that reported for other avian species with the exception of ostriches. As in mammals, the lowest clearance rate of the 3 fluoroquinolones was observed for marbofloxacin. Enrofloxacin was absorbed most rapidly, followed by marbofloxacin, then danofloxacin. The highest bioavailability was observed for danofloxacin followed by marbofloxacin, while very low bioavailability with significant conversion to ciprofloxacin was observed for enrofloxacin. Population analysis showed low intersubject variability for danofloxacin and marbofloxacin in contrast to that for enrofloxacin and its main metabolite, ciprofloxacin. Because of their more favorable pharmacokinetic properties after oral administration, either danofloxacin or marbofloxacin appears to be preferable to enrofloxacin for the treatment of susceptible bacterial infection in Japanese quail.

    The purpose of this study was to provide a reference for xeroradiographic and conventional radiographic anatomy of the bobwhite quail (Colinus virginianus) as a representative of the avian order Galliformes. The heads, bodies, wings, and pelvic limbs of four adult birds were radiographed using xeroradiographic and conventional radiographic techniques. Nine xeroradiographs and their corresponding conventional radiographs were selected, and the xeroradiographs labeled to illustrate the normal anatomy of these regions. A xeroradiograph of the tarsometatarsus of the domestic peacock (Pavo cristatus) was also included to demonstrate the metatarsal spur, which is not present in the quail

    Full Text Available The objective of this study was to estimate the variance components for body weight in Japanese quails by Bayesian procedures. The body weight at hatch (BWH and at 7 (BW07, 14 (BW14, 21 (BW21 and 28 days of age (BW28 of 3,520 quails was recorded from August 2001 to June 2002. A multiple-trait animal model with additive genetic, maternal environment and residual effects was implemented by Gibbs sampling methodology. A single Gibbs sampling with 80,000 rounds was generated by the program MTGSAM (Multiple Trait Gibbs Sampling in Animal Model. Normal and inverted Wishart distributions were used as prior distributions for the random effects and the variance components, respectively. Variance components were estimated based on the 500 samples that were left after elimination of 30,000 rounds in the burn-in period and 100 rounds of each thinning interval. The posterior means of additive genetic variance components were 0.15; 4.18; 14.62; 27.18 and 32.68; the posterior means of maternal environment variance components were 0.23; 1.29; 2.76; 4.12 and 5.16; and the posterior means of residual variance components were 0.084; 6.43; 22.66; 31.21 and 30.85, at hatch, 7, 14, 21 and 28 days old, respectively. The posterior means of heritability were 0.33; 0.35; 0.36; 0.43 and 0.47 at hatch, 7, 14, 21 and 28 days old, respectively. These results indicate that heritability increased with age. On the other hand, after hatch there was a marked reduction in the maternal environment variance proportion of the phenotypic variance, whose estimates were 0.50; 0.11; 0.07; 0.07 and 0.08 for BWH, BW07, BW14, BW21 and BW28, respectively. The genetic correlation between weights at different ages was high, except for those estimates between BWH and weight at other ages. Changes in body weight of quails can be efficiently achieved by selection.

    Extensive diversity has been described within the avian oropharyngeal trichomonad complex in recent years. In this study we developed clonal cultures from four isolates selected by their different ITS1/5.8S/ITS2 (ITS) genotype and their association with gross lesions of avian trichomonosis. Isolates were obtained from an adult racing pigeon and a nestling of Eurasian eagle owl with macroscopic lesions, and from a juvenile wood pigeon and an European turtle dove without clinical signs. Multi-locus sequence typing analysis of the ITS, small subunit of ribosomal rRNA (SSUrRNA) and Fe-hydrogenase (Fe-hyd) genes together with a morphological study by optical and scanning electron microscopy was performed. No significant differences in the structures were observed with scanning electron microscopy. However, the genetic characterisation revealed novel sequence types for the SSUrRNA region and Fe-hyd gene. Two clones were identified as Trichomonas gallinae in the MLST analysis, but the clones from the racing pigeon and European turtle dove showed higher similarity with Trichomonas tenax and Trichomonas canistomae than with T. gallinae at their ITS region, respectively. SSUrRNA sequences grouped all the clones in a clade that includes T. gallinae, T. tenax and T. canistomae. Further diversity was detected within the Fe-hyd locus, with a clear separation from T. gallinae of the clones obtained from the racing pigeon and the European turtle dove. In addition, morphometric comparison by optical microscopy with clonal cultures of T. gallinae revealed significant statistical differences on axostyle projection length in the clone from the European turtle dove. Morphometric and genetic data indicate that possible new species within the Trichomonas genus were detected. Taking in consideration the diversity in Trichomonas species present in the oral cavity of birds, a proper genetic analysis is highly recommended when outbreaks occur. Copyright © 2017 Elsevier B.V.

    Full Text Available Pharmacological study on Beijing grass (Bj. grass: Murdannia loriformis showed immunomodulator and anticancer activities. Thus, the effect of Bj. grass in diets was investigated in Japanese quails (aged 0-6 weeks on growth performances, humoral immunity and carcass characteristics. 708 1-day-old quails (Corturnix type which had no vaccination program were used in this study. They were experimented using completely randomized design and were divided into 6 treatments consisted of 4 replications with 27-31 heads each. The treatments were assigned as follows: Treatment 1 (T1 no vaccination and no Bj.grass, Treatment 2 (T2 vaccination and no Bj.grass, Treatment 3 (T3 vaccination and 3% Bj.grass, Treatment 4 (T4 vaccination and 6% Bj.grass, Treatment 5 (T5 vaccination and 9% Bj.grass and Treatment 6 (T6 vaccination and 10% Bj.grass juice (w/v. Vaccination program by 1 Newcastle disease + Infectious Bronchitis and 2 Pox were given at 1 and 3 weeks. Approximately 25% of quails were bled for determination of packed cell volume, gamma globulin levels and ND-HI titers. All male quails were put to sleep at 6 weeks. The results showed weight gain in the 3rd week was different in treatments using Bj. grass and treatments using control diet which body weight gain reduced when the level of Bj. grass increased (p 0.05. It was noted that not more than 6% Bj. grass could be used in quail diet without abnormal clinical signs. However, the more grass showed the tendency of poor weight gain. There were no differences in packed cell volume or gamma IgG level and ND-HI titers did not reach protection level. For carcass characteristics, Bj. grass 3% in diet gave the best carcass characteristics. (p < 0.05 In addition there was a dose-related reduction of abdominal fat (P=0.001.

    Full Text Available The Japanese quail Coturnix japonica originated from North Africa, Europe and Asia, is used worldwide as an experimental animal and model for aviculture. The current paper characterizes Eimeria bateri, Eimeria tsunodai and Eimeria uzura recovered from C. japonica. Based on the fact that quails have a global distribution, as are their coccidia, the findings of this study should provide the means for diagnosis of those Eimeria spp. in other regions and continents. Eimeria bateri showed the greatest intensity of infection and shed oocysts from the fourth day after infection; in contrast, E. tsunodai and E. uzura shed oocysts from the fifth day after infection. The three species shared a high degree of similarity and were all polymorphic. Yet, the application of line regressions, histograms and ANOVA provided means for the identification of these species. Finally, the algorithm was very efficient since verified that resultant values were not superimposed.

    Full Text Available The objective of this study was to design a classification range of the coefficients of variation (CV of traits used in experiments with eggtype Japanese quails (Coturnix coturnix japonica. The journal Revista Brasileira de Zootecnia was systematically reviewed, using the key word 'quail' during the period of January, 2000 to 2010. The CV of feed intake (g/bird/d, egg production (%/bird/d, egg weight (g, egg mass (g/bird/d, feed conversion ratio per dozen eggs (g/dozen, feed conversion ratio per egg mass (g/g, and egg specific gravity (g/mL were collected. For each parameter, CV were classified using the following median (MD and pseudo-sigma (PS ratio as follows: low (CV MD + 2PS. According to the results, it was concluded that each parameter has a specific classification range that should be taken into account when evaluating experimental precision.

    There has been a gradual increase in production and consumption of atrazine (ATR) in agriculture to meet the population rising demands. Female reproduction is necessary for growth and maintenance of population. However, ATR impact on females and particularly ovarian developmental toxicity is less clear. The aim of this study was to define the pathways by which ATR exerted toxic effects on ovarian development of ovary and hypothalamo-pituitary-ovarian (HPO) axis. Female quails were dosed by oral gavage from sexual immaturity to maturity with 0, 50, 250 and 500 mg ATR/kg/d for 45 days. ATR had no effect on mortality but depressed feed intake and growth and influenced the biochemical parameters. Notably, the arrested development of ovaries and oviducts were observed in ATR-exposed quails. The circulating concentrations of E2, P, LH and PRL were unregulated and FSH and T was downregulated in ATR-treated quails. The mRNA expression of GnRH in hypothalamo and LH in pituitary and FSH in ovary was downregulated significantly by ATR exposure and FSH and PRL in pituitary were upregulated. ATR exposure upregulated the level of P450scc, P450arom, 3β-HSD and 17β-HSD in ovary and downregulated ERβ expression in female quails. However, ATR did not change ERα expression in ovary. This study provides new insights regarding female productive toxicology of ATR exposure. Ovary and oviduct in sexually maturing females were target organs of ATR-induced developmental toxicity. We propose that ATR-induced developmental abnormality of ovary and oviduct is associated with disruption of gonadal hormone balance and HPO axis in female quails. - Highlights: • ATR triggers arrested development of ovarian and oviduct. • Ovary and oviduct are target organs of ATR-induced developmental toxicity. • Atrazine causes hormone adjustment disorder in female quails. • Atrazine upregulates steroidogenic factor and downregulates ERβ factor in ovary. • Atrazine disrupted the hypothalamo

    Full Text Available The experiment was carried outto determine the levels of vitamin K for meat quails (Coturnixcoturnixsp from 1 to 14 days of age. Atotal of 2200 birds were used, complete by random experimental design, with 8 treatments, 5 repetitions and 55 meat quails per experimental unit. The levels of vitamin K supplementation were 0; 0.7; 1.0; 1.3; 1.6; 1.9; 2.2; 2.5 mg/kg diets. The performance was measured through weighing weekly from the birds and feed, and at the end of the experiment was carried out collects blood and bones for the assessment of bone quality parameters. The levels of vitamin K supplementation had no influence on performance orbone quality, except thatthe bone density and calcium concentration of the femur and the bone density of the tibia showeda quadratic effect, with estimates of 0.98; 0.92 and 1.18 respectively. The length of the tibia showed a linear increase according to the levels of vitamin K. There was no effect in the concentration of serum calcium, but there was a quadratic effect in the concentration of alkaline phosphatase. The vitamin K supplementation did not affect the performance of the meat quails from 1 to 14 days of age, showing that the amount of vitamin K present in ground corn and soybean meal-based diets is sufficient to meet the needs of the birds’ performance.

    Full Text Available Objective: To investigate the effect of wild black mustard seed meal on thyroid hormones (thyroxine and thyroid-stimulating hormone in Japanese quails and also study the ability of FeSO4 to alleviate the possible negative effect of mustard meal on thyroid hormones in these birds for the first time. Methods: The experimental procedure was undertaken on 28 quails which were randomly assigned to a control and 6 test groups with 4 quails in each group for 28 days, during which the control group received basic diet with no mustard meal whereas the test groups (No. 2, 3 and 4 received mustard meal (5%, 10% and 15%, respectively and test groups (No. 5, 6 and 7 received FeSO4 (1%-treated mustard meal (5%, 10% and 15%, respectively on the basic of basic diet. Results: The group fed on 15% non-treated mustard seed meal had the least thyroxine level and its level backed to normal in group fed on 15% FeSO4-treated mustard seed meal although this group had the highest alanine transaminase and aspartate transaminase levels. Conclusions: We concluded that up to 10% FeSO4 mustard seed meal could be incorporated in the quail diet successfully with the least damage to thyroids and livers, but further investigations on these birds are still needed to confirm this hypothesis.

    In rats, dopamine (DA) facilitates male sexual behavior through its combined action on D1- and D2-like receptors, in the medial preoptic area (MPOA) as well as other brain areas. In Japanese quail, systemic injections of dopaminergic drugs suggested a similar pharmacology but central injections have never been performed. Recent electrophysiological experiments demonstrated that DA effects in the MPOA of quail are mediated mainly through the activation of alpha2-noradrenergic receptors. Previous studies of DA action on behavior used specific dopaminergic agonists/antagonists and therefore unintentionally avoided the potential cross-reaction with alpha2-receptors. The present study was thus designed to investigate directly the effects of DA on male sexual behavior and to test whether the interaction of DA with heterologous receptors affects this behavior. Intracerebroventricular (i.c.v.) injection of DA or NE inhibited copulation in a dose-dependent manner. Systemic injections of yohimbine, an alpha2-noradrenergic antagonist, modulated copulation in a bimodal manner depending on the dose injected. Interestingly, a behaviorally ineffective dose of yohimbine markedly reduced the inhibitory effects of DA when injected 15min before. Together, these results show for the first time that i.c.v. injections of DA itself inhibit male sexual behavior in quail and suggest that the interaction of DA with alpha2-receptors has behavioral significance.

  6. Ovarian radiographic and direct measurements of Japanese Quail ( Coturnix coturnix japonica submitted to light restriction

    M. Albuquerque

    Full Text Available ABSTRACT Often, in pet birds, any stimulus to lay eggs is unwanted in order to reduce reproductive diseases and disorders. The objectives of this study were: to determine the time necessary to promote ovary involution after an eight hour photoperiod using laying Japanese quails (Coturnix coturnix japonica; to connect the ovarian radiographic measurements with egg production; and to compare these measurements with direct ovary data obtained at necropsy. Birds were separated into three groups: 12h/24d (control group - 12h photoperiod for 24 days, 8h/24d and 8h/36d (8h photoperiod for 24 and 36 days. After euthanasia, all cadavers were x-rayed to measure ovary length and height. Birds were necropsied to measure ovarian length and weight. Results: radiographic ovary length demonstrated strong and positive correlation (r=0.96 with direct ovary length of all three groups; laying quails showed higher ovary height (p=0.025 and length (p=0.009 than non-laying quails; eight hours of artificial light per day promotes ovary length (p=0.025 and weight (p=0.009 reduction. Conclusions: radiography can estimate the ovary measure and indicate posture; an eight hour photoperiod of 24 days is not enough to promote ovarian regression, while the use of reduced photoperiod for 36 days promotes significant ovary involution.

    A contribution to a special issue on Hormones and Human Competition.Testosterone is theorized to influence status-seeking behaviors such as social dominance and competitive behavior, but supporting evidence is mixed. The present study tested the roles of testosterone and cortisol in the hawk-dove game, a dyadic economic decision-making paradigm in which earnings depend on one's own and the other player's choices. If one person selects the hawk strategy and the other person selects the dove strategy, the player who selected hawk attains a greater financial pay-off (status differentiation). The worst financial outcome occurs when both players choose the hawk strategy (status confrontation). Ninety-eight undergraduate students (42 men) provided saliva samples and played ten rounds of the hawk-dove game with another same-sex participant. In support of the hypothesis that testosterone is related to status concern, individuals higher in basal testosterone made more hawk decisions - decisions that harmed the other player. Acute decreases in cortisol were also associated with more hawk decisions. There was some empirical support for the dual-hormone hypothesis as well: basal testosterone was positively related to satisfaction in the game among low basal-cortisol individuals but not among high basal-cortisol individuals. There were no significant sex differences in these hormonal effects. The present findings align with theories of hormones and status-seeking behavior at the individual level, but they also open up new avenues for research on hormone profiles at the collective level. Our results suggest that the presence of two or more high-testosterone members increases the likelihood of status confrontations over a limited resource that can undermine collective outcomes.

    Whole-body autoradiography of DDT- 14 C, 2,2',4,5'-tetrachlorobiphenyl- 14 C and 2,2',3,3',4,4',5,6'=octachlorobiphenyl- 14 C in laying quails indicated a strong deposition of radioactivity in the yolk of the growing follicles and the egg, confirming this to be a significant excretion route of lipophilic environmental pollutants in laying birds. A specific uptake of DDT and octachlorobiphenyl, but not of tetrachlorobiphenyl, was observed in the cortical cords of the adrenals. The octachlorobiphenyl was concentrated also in the ovarian stroma. Both DDT and the tetrachlorobiphenyl were excreted in the bile juice to the small intestine. No such excretion of octachlorobiphenyl was observed, indicating its rate of metabolization to be low. All compounds were accumulated and stored in the body fat. A previously described specific accumulation of 2,2',4,5'-tetrachlorobiphenyl in the respiratory tract of mice was not observed in the quail. (author)

    Full Text Available Out of a sample batch of 20 Japanese quails, Pharaoh race, with an age of 100 days and weighing 245 g, approximately 200 eggs were collected at the peak phase of the laying period. The eggs were measured, weighed and broken, separating the albumen from the other components. The data obtained served to calculate the physical and morphological indices. Primary chemical composition, caloricity, heavy metals content were first determined, the following data being obtained: quail eggs albumen has an average weight of 7.1025±0.061g, an average volume of 7.158±0.09cm3, an average density of 1.0168±0.0139 g/cm3 and an index (of freshness of 0.0797±0.0015. The albumen contains: 86.76% water, 13.24% dry matter, 0.835% mineral matter, 11.37% protein, 1.03% non-nitrogenous extractive substances and a caloricity of 289.498 kJ for 100 g product. The average content of heavy metals in albumen was: 1.33*10-3 ppm, for cadmium; 8.83*10-2 ppm, for zinc; 1.005 ppm, for cooper and 0.0 ppm, respectively, for lead.

    1988-01-01

    Young Japanese quail (Coturnix japonica) were administered NaF for 16 d either in their diet or by esophageal intubation. Based on the total fluoride ion (Emg F-) intake over the l6-d experimental period, fluoride administered by intubation was at least six times more toxic than that fed in the diet. Dietary concentrations of 1,000 ppm F- (Emg F- for 16 d = approx. 144) produced no mortality, whereas intubated doses produced 73% or greater mortality in all groups administered 54 mg F- /kg/d or more (Emg F- for 16 d _ approx. 23 mg). GraphIc companson of the regression of log F- ppm in femurs/mg F- intake showed that fluoride levels in the femurs of quail administered fluoride by intubation were higher than in those administered fluoride in the diet.

    Northern bobwhite ( Colinus virginianus ; hereafter bobwhite) and scaled quail ( Callipepla squamata ) populations have suffered precipitous declines across most of their US ranges. Illumina-based first- (v1.0) and second- (v2.0) generation draft genome assemblies for the scaled quail and the bobwhite produced N50 scaffold sizes of 1.035 and 2.042 Mb, thereby producing a 45-fold improvement in contiguity over the existing bobwhite assembly, and ≥90% of the assembled genomes were captured within 1313 and 8990 scaffolds, respectively. The scaled quail assembly (v1.0 = 1.045 Gb) was ∼20% smaller than the bobwhite (v2.0 = 1.254 Gb), which was supported by kmer-based estimates of genome size. Nevertheless, estimates of GC content (41.72%; 42.66%), genome-wide repetitive content (10.40%; 10.43%), and MAKER-predicted protein coding genes (17,131; 17,165) were similar for the scaled quail (v1.0) and bobwhite (v2.0) assemblies, respectively. BUSCO analyses utilizing 3023 single-copy orthologs revealed a high level of assembly completeness for the scaled quail (v1.0; 84.8%) and the bobwhite (v2.0; 82.5%), as verified by comparison with well-established avian genomes. We also detected 273 putative segmental duplications in the scaled quail genome (v1.0), and 711 in the bobwhite genome (v2.0), including some that were shared among both species. Autosomal variant prediction revealed ∼2.48 and 4.17 heterozygous variants per kilobase within the scaled quail (v1.0) and bobwhite (v2.0) genomes, respectively, and estimates of historic effective population size were uniformly higher for the bobwhite across all time points in a coalescent model. However, large-scale declines were predicted for both species beginning ∼15-20 KYA. Copyright © 2017 Oldeschulte et al.

    Full Text Available A total of 240, one-day-old quail chicks (Coturnix coturnix japonica were used to study the effects of Artichoke leaf meal (ALM and vitamin E in diet on growth performance, ileal microbial populations and intestinal morphology in a 42-d trial. This experiment was performed as a completely randomized design with 4 replicates of 15 quails each, using a 4 × 2 factorial arrangement with diet and gender as the main effects. Four dietary treatments were formulated by addition of 2 levels (1.5 and 3 percent of ALM and 300 mg/Kg vitamin E to the basal diet. Supplementing basal diet with ALM did not improve growth performance at different rearing periods, whereas dietary vitamin E increased feed intake and body weight gain at day 21 of age (P. The ileal populations of lactobacillus and coliforms was not affected by dietary ALM treatments, whereas vitamin E increased the population of total aerobic bacteria (P≤0.04. The ileal villus height (P≤0.01 and crypt depth (P≤0.008 were reduced in quails fed on diets with ALM and vitamin E. The quails fed diets containing 3 percent ALM and 300 mg/Kg vitamin E had higher villus height:crypt depth ratio. The thickness of muscularies (P≤0.04 and mucosa (P≤0.0007 layers were decreased in birds fed diets containing ALM than control birds. Birds treated with ALM and vitamin E showed a shorter intestinal length (P≤0.02 and a lower pancereas relative weight. The results of this study showed that supplementing diet by ALM (1.5 and 3% and 300 mg/Kg vitamin E did not improve growth performance, ileal microbiota pupolations and intestinal morphometric indices in Japanese quail.

    Full Text Available This experiment was conducted to evaluate the ability of inhibition of aflatoxin B1 by various sources of selenium and to compare the effect of nano selenium and sodium selenite on humoral immunity of quails. The experiment was performed in a completely randomized design (CRD using six treatments and four replicates of ten quail chicks per replicate. Two hundred forty quails were divided in six groups vis. control: without aflatoxin B1 and without selenium. Group2: 1ppm aflatoxin B1 and without selenium.

In the trial, 120 Japanese quails were distributed in six treatments with four replicates of five birds each. The following treatments were applied: feed based on corn and soybean meal, containing graded BMBM inclusions (0, 1, 2, 3, 4 or 5%. After 42 days, 20 eggs per treatment were randomly collected for three consecutive days. Ten eggs were used for yolk and albumen sample collection, and ten for total egg sample collection. It was possible to detect the dietary inclusion of 1% BMBM in the egg and its fractions. Therefore, the technique of isotopes 13C and 15N is able of tracing since 1% inclusion level of BMBM in the diet of Japanese quails in eggs and their fractions.

    2012-03-01

    Full Text Available Michael Longley’s father has been a recurring presence in the poet’s work from his earliest to his most recent collection. This paper examines the exceptional strength of that bond reflected in the varied and changing ways in which the poet has responded to it – memorizing and mourning his loss; discovering through his father’s First World War stories a means of memorialising loss of life in contemporary conflicts and a way of facing the history of the twentieth century; confronting his own ageing and sense of mortality; and marking the specific, but also representative, generational history of his family. Close readings of key poems are offered to highlight Longley’s skills in meeting his own exacting standards of aesthetic propriety and moral and social responsibility for writers of elegy in order to avoid either exploitation of tragedy and loss, or facile gestures of consolation.

    Field studies of nesting success generally require visits by the investigator to the nests under study. Such visits may themselves influence nesting success, however, and this possibility has been discussed and investigated by a number of workers with a variety of bird species. Livezey (1980) reviewed the relevant literature for duck nests and noted that most studies failed to demonstrate differences in nesting success between visited nests and those not visited. Livezey (1980) found in his own work that nest abandonment may have occurred as a result of disturbance by observers but that nest predation was not related to time spent by observers at nests or number of observers approaching nests. Various components of nesting and breeding success in seabirds are thought to be adversely affected by human disturbance and nest visitation (Gillett et al. 1975, Robert and Ralph 1975, Ollason and Dunnet 1980). Upland, ground-nesting species have also been studied (e.g. Stoddard 1931, Evans and Wolfe 1967, Henry 1969, Roseberry and Klimstra 1970, Klimstra and Roseberry 1975), and, although conclusions have varied, a number of these workers found no effect of observers on nest-predation rates.

    1989-01-01

    Steroid autoradiography and systematic and intracranial steroid treatment were undertaken to determine the neuroanatomical loci which are sufficient to activate steroid sensitive behaviors in the Japanese quail. (1) Autoradiographic localization of steroid binding cells was performed on male and female quail brains using tritiated ( 3 H) testosterone (T), estradiol (E2), or 5α-dihydrotestosterone (DHT). The distributions of labelled cells in the quail brain following 3 H-T or 3 H-E2 injection and autoradiography were similar to one another. The distribution of labelled cells following 3 H-DHT autoradiography was limited in comparison to that following 3 H-T autoradiography. Males were found to have more labelled cells than females in nucleus taeniae. (2) Intracranial implantation of minute pellets of testoterone propionate (TP) and estradiol benzoate (EB) was performed to determine neuroanatomical loci at which steroids activate sexual behavior. Both TP and EB implants in the preoptic area (POA) activated male copulatory behavior. (3) Systematic injection of aromatase inhibitor prior to and concurrent with implantation completely blocked copulatory behavior in males with TP implants in the POA but failed to block copulation in males with EB implants in the POA. (4) Intact males and castrated males given 5 dosages of systematic EB treatment were tested for sexual behavior, and blood samples from each group were assayed for E2 concentration. (5) Midbrain DHTP implants were activated crowing without significantly stimulating peripheral androgen-sensitive tissues, but the effect on crowing was not localized to any one nucleus

    Full Text Available Background and Aim: Infectious coryza (IC or snot is an infectious upper respiratory disease affecting chickens and birds, including quails, and it is caused by Avibacterium paragallinarum. The symptoms of IC are facial swelling, malodorous nasal discharge, and lacrimation. This study aimed to isolate, identify, and serotype the A. paragallinarum of snot in quails and to determine the sensitivity and resistance to several antibiotics. Materials and Methods: Nine quails from Yogyakarta, Indonesia with typical snot disease symptoms were used in this study. The nasal swab was obtained and directly streaked onto a chocolate agar plate and blood agar plate (BAP, then incubated in 5% CO2 at 37°C for 24-48 h. Staphylococcus spp. was cross-streaked onto the BAP to show the satellite growth. The observation of the morphology of the suspected colony, Gram staining, and biochemical tests (catalase test, oxidase test, urease test, peptone test, and carbohydrate fermentation such as maltose, mannitol, lactose, and sorbitol are done to identify the species of bacteria.

    In the present study, we investigated the oxidative biotransformation of 2,2',4,4'-tetrabromodiphenyl ether (BDE-47) and 2,2',4,4',5-pentabromodiphenyl ether (BDE-99) by liver microsomes from wild lesser snow geese (Chen caerulescens caerulescens) and domesticated Japanese quail (Coturnix japonica). Formation of hydroxy-metabolites was analyzed using an ultra-high performance liquid chromatography-tandem mass spectrometry-based method. Incubation of BDE-47 with avian liver microsomes produced sixteen hydroxy-metabolites, eight of which were identified using authentic standards. The major metabolites formed by liver microsomes from individual lesser snow geese were 4-hydroxy-2,2',3,4'-tetrabromodiphenyl ether (4-OH-BDE-42), 3-hydroxy-2,2',4,4'-tetrabromodiphenyl ether (3-OH-BDE-47), and 4'-hydroxy-2,2',4,5'-tetrabromodiphenyl ether (4'-OH-BDE-49). By comparison, 4-OH-BDE-42 and 4'-OH-BDE-49, but not 3-OH-BDE-47, were major metabolites of Japanese quail liver microsomes. Unidentified metabolites included monohydroxy- and dihydroxy-tetrabromodiphenyl ethers. Incubation of BDE-99 with avian liver microsomes produced seventeen hydroxy-metabolites, twelve of which were identified using authentic standards. The major metabolites formed by lesser snow goose liver microsomes were 2,4,5-tribromophenol, 3-OH-BDE-47, 4'-OH-BDE-49, 4-hydroxy-2,2',3,4',5-pentabromodiphenyl ether (4-OH-BDE-90), and 5'-hydroxy-2,2',4,4',5-pentabromodiphenyl ether (5'-OH-BDE-99). By comparison, the major metabolites produced by liver microsomes from Japanese quail included 6-hydroxy-2,2',4,4'-tetrabromodiphenyl ether (6-OH-BDE-47) and 2-hydroxy-2',3,4,4',5-pentabromodiphenyl ether (2-OH-BDE-123), but not 3-OH-BDE-47. Unidentified metabolites consisted of monohydroxy-pentabromodiphenyl ethers, monohydroxy-tetrabromodiphenyl ethers and dihydroxy-tetrabromodiphenyl ethers. Another difference between the two species was that formation rates of BDE-47 and BDE-99 metabolites were greater with liver

    The distribution of /sup 115m/cadmium and its transfer to the egg were investigated in laying Japanese quail. Furthermore, the influence of estrogens on the tissue uptake of /sup 115m/cadmium was analyzed in adult male quail. Whole-body sections of a laying quail were prepared. Autoradiograms were made in birds killed 1, 24, 48, 96, 192 and 384 hours after a single injection of /sup 115m/cadmium chloride. During the first 48 hours following the injection, high concentrations of /sup 115m/cadmium were detected in the liver, kidneys, pancreas, proventriculus, uterus and small intestine. In eggs laid, /sup 115m/cadmium was detected only in the yolk. Its amount in the yolk was the highest in the second egg and decreased afterwards in the increasing order of oviposition sequence. The amount of the second egg was 0.21 percent of the given. In the male quail after estrogenization, the concentration of /sup 115m/cadmium increased in the femur and decreased in the liver, whole blood, and blood corpuscle, but was not affected at all in the kidney or blood plasma. These effects were dependent on the dose of estradiol benzoate. The cumulative contents of /sup 115m/cadmium in feces and urine for 192 hours were 28.42 +/- 0.73 (mean +/- standard error) percent of the dose given in laying quail, 25.83 +/- 0.91 percent in untreated males, and 27.81 +/- 0.63 percent in estrogenized males. It appeared that the increased uptake of cadmium in the femur by the estrogenization was roughly parallel with the formation of intramedullary bone. 22 references, 8 figures.

A total number of 648 birds in the peak of production was distributed in a random complete block experimental design, using a 2x3 factorial arrangement (2 corn particle sizes and 3 limestone particle sizes. Birds were designated to one of two blocks, with six replicates of 18 birds each. Mean geometric diameter (MGD values used were 0.617mm and 0.723mm (corn fine and coarse particle sizes, respectively, and 0.361mm, 0.721mm, and 0.947mm (limestone fine, intermediate and coarse particle sizes, respectively. The following treatments were applied: T1: fine corn feed, with 100% fine limestone; T2: fine corn feed, with 50% fine limestone and 50% intermediate limestone; T3: fine corn feed, with 50% fine limestone and 50% coarse limestone; T4: coarse corn feed, with 100% fine limestone; T5: coarse corn feed, with 50% fine limestone and 50% intermediate limestone; T6: coarse corn feed, with 50% fine limestone and 50% coarse limestone. The experiment lasted 112 days, consisting of 4 cycles of 28 days. No significant interaction was observed among corn and limestone particle sizes for any of the analyzed parameters. There were no significant effects (p>0.05 of the tested corn particle sizes on quail performance or egg quality. There were significant (p<0.05 isolated effects of limestone particle size only on the percentage of cracked eggs, which was reduced when birds fed 50% coarse limestone (0.947mm and 50% fine limestone (0.361mm as compared to those fed 100% fine limestone. Therefore, the inclusion of 50% coarse limestone (0.947mm is recommended for quail egg production.

    2009-04-01

    The author discusses the special role played by Shakespeare's masterpiece Hamlet in the history of psychoanalysis. Freud and many of his followers have treated Hamlet as if he were a real person inhibited by the Oedipus complex. In this presentation, Hamlet is understood as the embodiment of a brilliant artistic endeavor aimed at both revealing and concealing the power of this complex. The author proposes that, if Hamlet is autobiographical, it expresses Shakespeare's inability to mourn and love until a childhood homosexual memory has emerged. Hidden in Hamlet is a cure through the recall of a childhood memory.

    The author describes her father's experience of being a Holocaust survivor and how his unfinished mourning contributed to her struggle with muteness, her own story being dwarfed by the magnitude of her father's losses. When her non-Jewish mother is chosen to be honored by Yad Vashem, the ceremony proves unexpectedly powerful. The witnessing by community, through the Internet, helps dissolve the shame and isolation, heals some of the trauma, and promotes greater psychological freedom. In creating this paper, the author memorializes her parents and her lost relatives, and succeeds in working through much that had haunted her.

    Two Japanese quail strains, respectively atherosclerosis-susceptible (SUS) and -resistant (RES), have been shown to be good models to study cholesterol metabolism and transportation associated with atherosclerosis. Our objective was to examine possible difference in cecal microbiota between these strains when fed a control diet and a cholesterol enriched diet, to determine how host genotype and diet could affect the cecal microbiome that may play a part in cholesterol metabolism. A factorial study with both strains and two diets (control, cholesterol) was carried out. Cecal content was collected from 12 week old quail that have been on their respective diets for 6 weeks. DNA was extracted from the samples and the variable region 3-5 of the bacterial 16S rRNA gene was amplified. The amplicon libraries were subjected to pyrosequencing. Principal Component Analysis (PCA) of β-diversity showed four distinct microbiota communities that can be assigned to the 4 treatment groups (RES/control, RES/cholesterol, SUS/control, SUS/cholesterol). At the Phylum level, the 4 treatment groups has distinct Firmicutes community characteristics but no significant difference in Bacteroidetes. Eubacterium dolichum was rare in RES/control but became overabundant in RES/cholesterol. An unclassified species of Lactobacillaceae was found in abundance in SUS/control but the same species was rare in RES/cholesterol. On the other hand, two Lactobacillus species were only found in RES/control and an unclassified Lachnospiraceae species was abundant in RES/cholesterol but rare in SUS/control. The abundance of four species of Lachnospiraceae, three species of Ruminococcaceae and one species of Coprobacillaceae was positively correlated with plasma Total Cholesterol, plasma LDL, and LDL/HDL ratio. Our study of cecal microbiota in these quail has demonstrated that selection for susceptibility/resistance to diet induced atherosclerosis has also affected the quail's cecal environment to host

    The outbreak of bovine spongiform encephalopathy (BSE) disease in cattle, known as m ad cow disease , make the European commission to take an action for preventing the spread of such disease by banning the feeding ruminant tissue and animal by-products to farm animals. This study suggested to compare between two basal diets originated from either plants or animal and their effects on some physiological parameters related to the bird growth. A total number of 800 one day old unsexed Japanese quails were used in this study. Quails were divided equally into two groups containing 400 birds each. Each group contained 4 replicates of 100 birds. Group one the birds were fed on animal diet and group two fed on plant diet. The two diets contained 24% crude protein (CP) and 4% fat and contains 3200 Kcal/kg diet in starter, while the layer diet contained 21% CP and 4% fat and contains 3000 Kcal/kg diet. Growth data were obtained by weighing the quails individually every week until 6 th weeks, 6 th months and 1 2th months. Eggs were collected daily and weighed for eight months starting from the onset of first egg lying. At 8 th month, a sample of 8 quails was sacrificed, organ weighted and blood samples were collected. Carcass composition was performed to determine % fat, % protein, % ash and total moisture. Hematological and histological parameters, liver and kidney functions, total protein, albumin, globulin, estradiol, testosterone, cholesterol and total lipids were evaluated. The results showed significant increase in body weights gain in one and three weeks only in animal protein diet but no difference were shown between animal and plant diet after 4 weeks and until 12 month. No difference between animal and plant diets were noted in total dry solids (TDS), fat %, ash and protein of TDS and egg production. Levels of serum estradiol, testosterone, total protein, albumin, hematological parameters and total lipids showed non-significant values. The histological parameters

    This experiment was carried out to determine the effects of the usage of dried brewing yeast in quail diets on laying performance, egg traits and blood parameters. A total of 240 Japanese quails (Coturnix coturnix japonica) aged 10 weeks were randomly allocated into one control group and three treatment groups. Each group was divided into five replicates as subgroups, comprising 12 quails each. Dried brewing yeast (Saccharomyces cerevisiae) was used at the levels of 1.5%, 3.0% and 4.5% in the diets of the first, second and third treatment groups, respectively. Soyabean meal was replaced with dried brewing yeast. The diets were formulated to be isocaloric and isonitrogenous. The experimental period lasted 18 weeks. Dietary treatments did not significantly affect body weight, daily feed intake, daily protein intake, egg production, egg weight, feed efficiency, mortality, egg shell thickness, egg albumen index, egg yolk index, egg Haugh unit, the percentages of egg shell, albumen and yolk, excreta moisture and small intestinal pH. Inclusion of 3% and 4.5% dried brewing yeast in diets reduced egg yolk cholesterol concentration as mg per yolk and mg per g yolk (P brewing yeast was significantly lower (P brewing yeast resulted in significant increases (P brewing yeast. It is concluded that dried brewing yeast can be used up to 4.5% in the diets of laying quails without adverse effects on the measured parameters.

    This study evaluated the impact of oral perfluorooctanoic acid (PFOA) on Japanese quail at concentrations found in American and Belgian workers at PFOA manufacturing facilities. Three arms of the immune system were tested; T cell, B cell, and innate immunity. After 6 weeks exposure, quail were challenged with E. coli infection to test the ultimate measure of immunotoxicity, disease resistance. The T cell response was lower in the high exposure groups. Antibody mediated, and innate immune responses were not different. Growth rate was higher, whereas thyroid hormone levels were lower in PFOA-exposed birds. Morbidity/mortality from disease challenge was not different among the control and PFOA-exposed groups, and no overt PFOA toxicity was observed pre-disease challenge. Although PFOA at ‘worst case scenario’ levels caused T cell immunosuppression, this did not translate into increased disease susceptibility, demonstrating that immunotoxicity testing must be interpreted with caution since disease resistance is the ultimate concern. -- Highlights: •Birds orally exposed to high levels of PFOA for 8 wks showed no signs of toxicity. •PFOA exposure caused immunotoxicity by suppressing the T cell mediated response. •PFOA exposure did not affect antibody mediated, or innate immunity. •PFOA exposure did not cause increased morbidity/mortality after E. coli infection. •PFOA exposed birds showed endocrinological changes that may warrant further study. -- Oral exposure of quail to the pollutant, PFOA, resulted in hormonal and immunological changes, but did not compromise disease resistance after challenge by a common avian pathogen

    This study was designed to evaluate the protective effects of Arctium lappa L. root extracts (AREs) from different extraction methods (aqueous, ethanol, chloroform and flavone) on atherosclerosis. Quails (Coturnix coturnix) were subjected to high fat diet, with or without one of the four different AREs or positive control simvastatin. Blood samples were collected before treatment, after 4.5 weeks or ten weeks to assess lipid profile (Levels of total cholesterol (TC), Triacylglycerol (TG), low-density lipoprotein (LDL) and high-density lipoprotein (HDL)). After ten weeks, the serum levels of nitric oxide (NO) as well as antioxidant and pro-oxidative status (Levels of malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), glutathione (GSH), nicotinamide adenine dinucleotide phosphate (NADPH) and glutathione peroxidase (GSH-Px)) were measured. Furthermore, aortas were collected after ten weeks treatment, aorta lipid contents (TC, TG and LDL) were assessed, and histology was used to confirm atherosclerotic changes. The results indicated that high fat diet significantly deteriorated lipid profile and antioxidant status in quail serum, while all the extracts significantly reverted the changes similar to simvastatin. Aorta lipid profile assessment revealed similar results. Histology on aortas from quails treated for ten weeks confirmed atherosclerotic changes in high fat diet group, while the extracts significantly alleviated the atherosclerotic changes similar to simvastatin. Among the different extracts, flavones fraction exerted best protective effects. Our data suggest that the protective effects of AREs were medicated via hypolipidemic and anti-oxidant effects. Underlying molecular mechanisms are under investigation.

    A review of what is known about avian physiology and the biological effects of DDE suggests that some benefit to peregrine falcon egg condition could be attained by artificially feeding DDE free prey to the female from the time of her arrival on the nesting grounds until completion of egg laying; the magnitude of potential benefit is unknown. Sporadic efforts in the past demonstrated the need for precision methods of prey delivery. Two methods were developed and tried; providing dead prey items by dropping them in a day perch, and delivery of live prey by remotely controlled release from compartments positioned at the top of the cliff occupied by the falcons. Maintaining quail in the day perch for 21 days resulted in at least one and probably two meals for the female peregrine. Of 16 live birds released (mostly pigeons) 13 were pursued and three caught. Blinding the pigeons with tape proved to be necessary to enable capture. Also, some reluctance of the male peregrine to attack pigeons was observed, and problems with equipment, visibility, and the proximity of the falcons to the release box were encountered. Manpower was the most significant resource requirement. Baiting of great-horned owls, possibly leading to owl attack on the falcons, is judged to be the largest detrimental effect of supplemental feeding. It is recommended that supplemental feeding be reserved for falcons or eyries where complete reproductive failure is expected. Plumage documentation photography was successfully conducted by a remotely controlled camera as an aid to identification of individual falcons. American robin, red-winged blackbird, starling, white-throated swift, bluebird, and mourning dove were among natural prey consumed by the peregrines before completion of egg laying. All activities in close proximity to the cliff were conducted at night to preclude direct disturbance of the falcons.

    Full Text Available Antioxidant effect of dietary soapwort extract supplementation was studied in growing Japanese quails suffering from chronic intermittent cold stress. For this purpose, a total of ninety 15-d-old quails were divided into three groups with three replicates. Chronic intermittent cold stress was applied every night between 22.00 to 06.00 h; starting at 14 °C for the first week, and gradually weekly lowered to 8 °C. Three groups were fed with corn-soy based standard diets supplemented with 0, 50, and 100 ppm soapwort extract for four weeks. At the end of the study, three males and three females were slaughtered to determine total antioxidant and oxidant status of serum, malondialdehyde, glutathione, glutathione peroxidase activity, superoxide dismutase of liver and heart tissues. Although the dietary soapwort extract had no effect on serum total antioxidant capacity, it significantly lowered the total oxidant status of serum in cold stressed quails. Glutathione and superoxide dismutase enzyme activity of liver and heart tissues were similar among groups. While the dietary soapwort extract had no effect on glutathione peroxidase activity of the heart tissue, it significantly increased glutathione peroxidase activity in the liver tissue. In relation to the control group, malondialdehyde concentrations in the liver and heart tissues were significantly lower in soapwort extract groups. These data suggest that dietary soapwort extract could alleviate the detrimental effects of oxidative stress in growing Japanese quails exposed to cold stress.

    One of the basic steps in objective analysis of sperm motility is the subdivision of a motile sperm population into slow, medium and rapid categories based on their velocity. However, for CASA analysis of quail sperm, the velocity values for categorization of slow, medium and rapid sperm have not yet been standardized. To identify the cut-off values of "velocity curvilinear" (VCL) for quail sperm categorization, we captured and analysed 22,300 tracks of quail sperm using SCA ® -CASA. The median and mean VCL values were 85 and 97 μm/s. To define the VCL cut-off values, we used two methods. In the first, we identified the upper (rapid sperm) and lower (slow sperm) cut-off values using: (i) median VCL ± 25% or ± 50% or ± 75% of median VCL value; (ii) first and third quartile values of VCL data (i.e. 25% cut-off setting); and (iii) 33% and 66% of VCL data. Among these settings, sperm categories and their corresponding motility characteristics recorded using the "25%" setting (i.e. slow ≤36 ≤ medium ≤154 ≤ rapid) were found the most realistic and coherent with male ranking by fertility. In the second method, we calculated heteroscedasticity in the total VCL data using PCA and the two-step clustering method. With this approach, the mean of the high and low clusters was 165 and 51 μm/s, respectively. Together, the mean from two methods suggested that, for SCA ® -CASA categorization of quail sperm, sperm should be classed as "rapid" at VCL ≥160 μm/s and "slow" at VCL ≤45 μm/s. © 2017 Blackwell Verlag GmbH.

    The aim of this study was to investigate the role of heat shock protein 70 (Hsp70) in oxidative stress and inflammatory damage in the spleen of quails which were induced by cold stress. One hundred ninety-two 15-day-old male quails were randomly divided into 12 groups and kept at 12 ± 1 °C to examine acute and chronic cold stress. We first detected the changes in activities of antioxidant enzymes in the spleen tissue under acute and chronic cold stress. The activities of glutathione peroxidase (GSH-Px) fluctuated in acute cold stress groups, while they were significantly decreased (p stress. The activities of superoxide dismutase (SOD), inducible nitric oxide synthase (iNOS), and nitric oxide (NO) content were decreased significantly (p stress groups. Malondialdehyde (MDA) content was significantly increased (p stress except the 0.5 h group of acute cold stress. Besides, histopathological analysis showed that quail's spleen tissue was inflammatory injured seriously in both the acute and chronic cold stress groups. Additionally, the inflammatory factors (cyclooxygenase-2 (COX-2), prostaglandin E synthase (PTGES), iNOS, nuclear factor-kappa B (NF-κB), and tumor necrosis factor-a (TNF-α)) and Hsp70 mRNA levels were increased in both of the acute and chronic cold stress groups compared with the control groups. These results suggest that oxidative stress and inflammatory injury could be induced by cold stress in spleen tissues of quails. Furthermore, the increased expression of Hsp70 may play a role in protecting the spleen against oxidative stress and inflammatory damage caused by cold stress.

    The main objectives of this study were to detect the most appropriate random regression model (RRM) to fit the data of monthly egg production in 2 lines (selected and control) of Japanese quail and to test the consistency of different criteria of model choice. Data from 1,200 female Japanese quails for the first 5 months of egg production from 4 consecutive generations of an egg line selected for egg production in the first month (EP1) was analyzed. Eight RRMs with different orders of Legendre polynomials were compared to determine the proper model for analysis. All criteria of model choice suggested that the adequate model included the second-order Legendre polynomials for fixed effects, and the third-order for additive genetic effects and permanent environmental effects. Predictive ability of the best model was the highest among all models (ρ = 0.987). According to the best model fitted to the data, estimates of heritability were relatively low to moderate (0.10 to 0.17) showed a descending pattern from the first to the fifth month of production. A similar pattern was observed for permanent environmental effects with greater estimates in the first (0.36) and second (0.23) months of production than heritability estimates. Genetic correlations between separate production periods were higher (0.18 to 0.93) than their phenotypic counterparts (0.15 to 0.87). The superiority of the selected line over the control was observed through significant (P egg production in earlier ages (first and second months) than later ones. A methodology based on random regression animal models can be recommended for genetic evaluation of egg production in Japanese quail. © 2017 Poultry Science Association Inc.

    Full Text Available This study was conducted to investigate the effects of dietary Nigella sativa meal (NSM on the growth performance, blood parameters, carcass characteristics, egg yolk cholesterol and meat quality in Japanese quail. For this purpose 300 one-day old Japanese quail chicks in a completely randomized design was used with five treatments in four replicates containing 15 birds each(. The experimental diets were control group (without NSM and diets containing 5, 10, 15 and 20% of NSM. Feed intake of birds fed diets with 5 and 15% of NSM were statistically higher than control group. Weight gain in birds fed with 15% of NSM was significantly higher than control group. Feed conversion ratio of birds fed diets with 20% of NSM was statistically higher than control. No significant treatment effect was observed on egg yolk cholesterol, blood parameters (including triglyceride, HDL and total cholesterol concentrations and meat quality parameters (TBA, WHC, Dripping loss, Cooking loss. And also the use of different levels of NSM had no any significant effect on internal organs weight, except gizzard. NSM significantly decreased feed costs compared to control group. So, by using NSM up to 15% in Japanese quails diets, can improve weight gain and feed conversion ratio and decrease feed and meat production costs.

    In the present study we detailed the distribution of GFAP-immunopositive structures within the central nervous system of the Japanese quail. Different fixation and embedding procedures were applied. The best results were obtained on frozen cryostatic sections from freshly dissected brains subsequently fixed by a short immersion in cold acetone. Immunopositive structures were observed both with immunofluorescence, and with immunoperoxidase methods. Immunoreactive cell bodies and processes were observed within the whole central nervous system, and different cell types can be identified on the basis of their topographical location and morphology. A first class of astrocytes is composed of intensely stained unipolar cells lining the inner surface of the pia mater and the large blood vessels. A second type is represented by multipolar astrocytes of variable size, provided with an irregular cell body. The last type is represented by similar elements, showing an immunonegative cell body, that can be identified only by the presence of converging processes. These three types of cells, and several isolated processes, show a differential distribution within the quail central nervous system, both in the grey and in the white matter. Present results suggest that GFAP may represent a good marker for at least part of the astroglial population in quail.

    Full Text Available A study was conducted to determine the effect of foam extract on sperm motility in the male Japanese quail (Coturnix coturnix japonica. Adult male quails (<12 weeks of heavy body weight strain were housed in individual cages and divided into 5 groups according to the size of their cloacal glands. The data indicated that the size of the cloacal gland was positively correlated with the frequency of foam secretion and total foam production. One gram of freshly collected clean foam was mixed with 1.0 mL of normal saline and homogenized for 10 minutes. After centrifugation at 35 000 rpm, the supernatant was used as 100% foam extract. The extract was diluted to 1:40, 1:20, 1:10, and 1:4 with normal saline to produce 2.5, 5.0, 10, and 25% foam extracts, respectively. 5% foam extract enhanced sperm survival at room temperature (30°–35°C for 2 to 3 hrs, whereas higher concentrations (10% and above suppressed sperm motility. From this study, it may be concluded that foam secretion and quantity of foam are directly proportional to the size of the cloacal gland and that the foam enhances and prolongs sperm motility, in vitro at an optimum concentration of 5%.

    Birds are exposed to Pb by oral ingestion of spent Pb shot as grit. A paucity of data exists for retention and clearance of these particles in the bird gastrointestinal tract. In the current study, northern bobwhite quail (Colinus virginianus) were orally gavaged with 1, 5, or 10 Pb shot pellets, of 2-mm diameter, and radiographically followed over time. Blood Pb levels and other measures of toxicity were collected, to correlate with pellet retention. Quail dosed with either 5 or 10 pellets exhibited morbidity between weeks 1 and 2 and were removed from further study. Most of the Pb pellets were absorbed or excreted within 14 d of gavage, independent of dose. Pellet size in the ventriculus decreased over time in radiographs, suggesting dissolution caused by the acidic pH. Birds dosed with one pellet showed mean blood Pb levels that exceeded 1,300 µg/dl at week 1, further supporting dissolution in the gastrointestinal tract. Limited signs of toxicity were seen in the one-pellet birds; however, plasma δ-aminolevulinic acid dehydratase (d-ALAD) activity was persistently depressed, suggesting possible impaired hematological function. © 2010 SETAC.

    This study was conducted to verify whether vitamin (Vit) E or natural clay as feed additives has the potential to modulate the deleterious effects resulting from exposure to cadmium (Cd) in growing Japanese quail. 648 Japanese quail chicks (1 week old) were used to evaluate the effects of dietary Cd (0, 40, 80 and 120 mg/kg diet) and two levels of Vit E (0, 250 mg/kg diet) or two levels of natural clay (0 and 100 mg/kg diet) to study the influences of Cd, Vit E, clay or their different combinations on growth performance, carcass traits, some blood biochemical components and Cd residues in muscles and liver. Live BW and weight gain of quails were linearly decreased with increasing dietary Cd levels. Moreover, feed conversion was significantly worsened with increasing Cd level. Mortality percentage was linearly increased as dietary Cd level increased up to 120 mg/kg diet. Carcass percentage was linearly decreased as dietary Cd level increased. While, giblets percentage were linearly and quadratically differed as dietary Cd level increased. Cd caused significant changes in total plasma protein, albumin, globulin, A/G ratio, creatinine, urea-N and uric acid concentrations as well as ALT, AST and ALP activities. Increasing dietary Cd level was associated with its increase in the muscles and liver. Dietary supplementation with 250 mg of Vit E/kg diet or 100 mg clay/kg improved live BW, BW gain and feed conversion when compared with the un-supplemented diet. Quails fed diet contained 250 mg Vit E/kg and those fed 100 mg clay/kg had the highest percentages of carcass and dressing than those fed the un-supplemented diet. Blood plasma biochemical components studied were better when birds received 250 mg of Vit E/kg diet and those received 100 mg clay/kg. Cd residues in the muscles and liver were significantly less in the birds had 250 mg of Vit E/kg or those received 100 mg clay/kg diet than those un-supplemented with Vit E.

    The effect of substitution of dietary cotton seed oil (CSO) by used restaurant oil (URO) with different percentages 25% group 2 (G2), 50% group 3 (G3) and 100% group 4 (G4) in Japanese quail diets on the fatty acids composition of their meat especially polyunsaturated fatty acids (PUFA). The effect of gamma irradiation doses (1.5, 3 and 5 kGy) at frozen storage -18 C (degree) for 2 and 4 months in comparison with unirradiated and un storage were studied. The total saturated fatty acids (SFA) in quail meat fed G4 diet (100% URO) increased significantly in comparison with SFA in G2 (25% URO) and G3 (50% URO) but there is no significant effect with G2 and G3 in comparison with G1 (100% CSO).The monounsaturated fatty acids (MUFA) and polyunsaturated fatty acids (PUFA) were not affected by G2 and G3 diet. Also, linoleic acid (C 18:2, n-6) had the same trend in those groups with range (32.75% to 33.35%). It is concluded that feeding a diet with URO 25% and 50% conserve the content of linoleic acid and the content of PUFA in quail meat. The irradiation doses and storage periods had no significant effect on the linoleic acid, MUFA and PUFA content.

    Phenotypic plasticity of organ size allows some animals to manage fluctuations of resource quality or availability. Here, we examined the phenotypic plasticity of the gastrointestinal tract of king quail (Coturnix chinensis) in a diet-fibre manipulation study. Quail were offered either a control low-fibre (high-quality) food (8.5% neutral-detergent fibre; NDF), or one of two experimental diets of higher fibre contents of 16% NDF (i.e. low-quality food). To examine whether phenotypic plasticity of organ size was associated with the fibre content per se, or as a consequence of diluting the diet energy contents by adding fibre, one of the high-fibre feeds was 'balanced' with additional energy to match that of the low-fibre control diet. Total empty dry mass of the gastrointestinal tract was significantly heavier among birds offered the unbalanced high-fibre diet as compared with those offered the control diet, with birds offered the fibrous but energy-balanced diet having guts of intermediate size. The heavier entire-gut mass (dry) of quail offered the unbalanced high-fibre diet was associated mainly with these birds having significantly heavier gizzards. Notably, the larger gizzard in the birds offered the unbalanced high-fibre diet was associated with marked increases in their metabolisability (digestion) of diet fibre. Our findings suggest that the available energy in the diet may be more important for eliciting phenotypic changes in the gut of these herbivorous birds rather than simple physical effects of diet fibre on feed intakes or on muscular compensation to fibrous ingesta. © 2014.

    Facebook not only changed the way we communicate but also the way we mourn and express grief. The social networking site allows users to interact with deceased users' walls after death. This study utilized textual analysis to categorize Facebook posts ( N = 122) on 30 deceased users' walls according to uses and gratifications theory. Most posts were found to be motivated by entertainment, followed by integration and social interaction. Facebook users posted memories, condolences, and interacted with friends and family members in the deceased user's network. Implications and potential future research are discussed.

    Full Text Available The objective of the study was to observe the effect of experimental hypodynamy simulating weightlessness in space on the structure, ultrastructure and alkaline phosphatase activity of kidney in Japanese quail (Coturnix coturnix japonica. Two days after hatching, the quails were suspended in special shirts below the cage ceiling so their feet did not touch the floor. They could consume food and water ad libitum. Experimental animals were sacrificed after 14, 21, 28, 35, 42, 49 and 56 days of hypodynamy. Birds of the same age, hatched at the same time, and fed the same diet were used as a control. Samples of kidney were processed for light (LM and transmission electron microscopy (TEM, and alkaline phosphatase (AP analysis. Short-term (14–28 days hypodynamy caused no marked damage to the structure and ultrastructure of kidneys. However, after long-term (35–59 days hypodynamy, morphological changes were observed in some cells of the proximal and distal tubules. The dying cells in proximal tubules, observed in semi-thin sections by LM, were dark and contained a nucleus of irregular shape. Observation by TEM showed that their nucleus was dark and shrivelled and the electron-dense cytoplasm contained long, dense, rod-shaped mitochondria with thin mitochondrial cristae. Microvilli were present on the apical surface of cells and formed a brush border. Sporadic dying cells were also observed in distal tubules. Large, light vacuoles were found in the cytoplasm of cells of collecting tubules, however, the structure of renal corpuscles and medullary loops remained undisturbed. Microscopical analysis by means of a direct TUNEL reaction on days 35 to 59 of hypodynamy showed a moderate occurrence of cellular apoptosis in the proximal and distal tubules of experimental Japanese quail. The activity of AP in the brush border of the proximal tubules on days 14–29 of hypodynamy was normal in experimental animals and showed no significant differences in

    Prostate cancer is a highly prevalent disease with a high likelihood of survival. If treated, survivors live with significant and lasting treatment-related side effects. Surgical treatment is associated with urinary incontinence and erectile dysfunction, and radiation leads to urinary and bowel irritability as well as erectile dysfunction. Patients who undergo hormonal treatment cope with sexual dysfunction, bone density loss, hot flashes, mood symptoms, and cardiac and metabolic disorders. Functional losses have a significant impact on patients and their partners' quality of life and are associated with distress and psychosocial morbidity. Psychosocial treatment is largely unavailable in usual care, but has been shown to reduce distress, to increase positive reappraisal of the illness, and to contribute to the recovery of sexual intimacy. Treatment for grief and mourning, typical reactions to loss, has not been introduced into psychosocial interventions but is increasingly recognized as a path toward a 'new normal' after prostate cancer treatment. © 2015 S.

    The circulating lipids of birds play essential roles for egg production and as an energy source for flight and thermogenesis. How lipid-lowering pharmaceuticals geared to prevent heart disease in humans and that are routinely released in the environment affect their metabolism is unknown. This study assesses the impact of the popular drug gemfibrozil (GEM) on the plasma phospholipids (PL), neutral lipids (NL), and nonesterified fatty acids (NEFA) of bobwhite quails (Colinus virginianus). Results show that bird lipoproteins are rapidly altered by GEM, even at environmentally-relevant doses. After 4 days of exposure, pharmacological amounts cause an 83% increase in circulating PL levels, a major decrease in average lipoprotein size measured as a 56% drop in the NL/PL ratio, and important changes in the fatty acid composition of PL and NEFA (increases in fatty acid unsaturation). The levels of PL carrying all individual fatty acids except arachidonate are strongly stimulated. The large decrease in bird lipoprotein size may reflect the effects seen in humans: lowering of LDL that can cause atherosclerosis and stimulation of HDL that promote cholesterol disposal. Lower (environmental) doses of GEM cause a reduction of %palmitate in all the plasma lipid fractions of quails, but particularly in the core triacylglycerol of lipoproteins (NL). No changes in mRNA levels of bird peroxisome proliferator-activated receptor (PPAR) could be demonstrated. The disrupting effects of GEM on circulating lipids reported here suggest that the pervasive presence of this drug in the environment could jeopardize reproduction and migratory behaviours in wild birds.

    Full Text Available We analyze what we call the novel of mourning in opposition to the novel of historical memory. While both assume a critical position with respect to the violence of the 20th century in Spain, they differ in how they deal with the losses of the past. The novel of historical memory, influenced by the internationalization of memory discourses and movements, seeks to combat the imposed forgetting through a literary recovery of forgotten cases from the past. The novel of mourning, however, seeks to break this dichotomy between forgetting/memory, understanding that the losses of the past are unrecoverable and that a more just future is only achievable by recognizing the past’s tragic nature: more than a (reopening or closing of wounds, it means living with them, also permitting a way of relating to other tragedies that would otherwise be foreign to us. As an example we analyze Ernesto Pérez Zúñiga’s Santo Diablo (2004.

    Aflatoxins (AFs) contamination of foods and live-stock feeds is an ongoing problem. In this research, the amelioration of aflatoxicosis in Japanese quails was examined by the radiation processing of their contaminated-diets, as a physical detoxifying method. Diets contaminated with two different levels of AFB 1 (2 or 5 mg kg -1 diet) were subjected to 10, 20, or 30 kGy and fed to growing Japanese quails for 5 weeks. The physiological and biochemical responses were evaluated for irradiation ability to reduce the deleterious effects of 2 and 5 mg AFB 1 kg -1 diet. A total of 270 seven-day-old Japanese quail chicks were assigned to 2 factorial arrangements of nine treatments (level of toxin and radiation dose) each consisted of three replicates with 10 quails per pen. The significant adverse effect of AFB 1 on the food consumption, body-weight gain, food conversion ratio, mortality rate and internal organ weights, from the first week onwards, were determined. Radiation processing reduced concentration of AFB 1 in all experimental diets and significantly reduced the deleterious effects of AFB 1 on food consumption, body-weight gain, food conversion ratio, and the relative weights of most observed organs, as a function of radiation dose. Muscles, liver, kidneys and heart tissues were analyzed for aflatoxin (AF) residues. The residual level of AFB 1 was significantly higher in liver than in kidneys, muscles or heart. The level in the observed organs and the muscles was lower in those received irradiated diet at high 30 kGy. Plasma samples were tested for glucose, triglyceride, cholesterol, aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), urea and creatinine. They were significantly increased in AF treated groups in comparison with those received AF-containing diet and irradiated up to 30 kGy. Birds ate contaminated diet with both level of toxin were suffered from the lower level of total proteins, albumin, globulin, phosphorus and

    The purpose of this study was to know the production performance and economic analysis in quail which use probiotic supplementation to alternate antibiotic growth promoter (AGP) to feed consumption, water consumption, egg production, egg mass, feed conversion, and feed efficiency. About 240 quails ( Coturnix coturnix japonica) at 14 weeks of age were completely randomized into four treatments, each treatment consisted of six replications and each replication consisted by 10 heads. The treatment was T0 (organic feed without AGP and without probiotic), T1 (organic feed + 0.001% AGP), T2 (organic feed + 0.005% probiotic in feed), and T3 (organic feed + 0.005% probiotic in drinking water). The probiotic consist of 1.2×10 5 CFU/g of Lactobacillus casei and Lactobacillus rhamnosus . The results showed that the probiotic supplementation both in feed and water give a significant impact to feed consumption, water intake, feed conversion, feed efficiency, and quail day production, but no statistical difference of egg mass. The T3 also show the most profitable business analysis, which has the best result in income, profit, break-even point, return cost ratio, benefit-cost ratio, and return on investment. It can be concluded that giving 0.005% probiotic in drinking water to get the best egg production and profit.

    1. The aim of the present study was to estimate genetic parameters for average egg weight (EW) and egg number (EN) at different ages in Japanese quail using multi-trait random regression (MTRR) models. 2. A total of 8534 records from 900 quail, hatched between 2014 and 2015, were used in the study. Average weekly egg weights and egg numbers were measured from second until sixth week of egg production. 3. Nine random regression models were compared to identify the best order of the Legendre polynomials (LP). The most optimal model was identified by the Bayesian Information Criterion. A model with second order of LP for fixed effects, second order of LP for additive genetic effects and third order of LP for permanent environmental effects (MTRR23) was found to be the best. 4. According to the MTRR23 model, direct heritability for EW increased from 0.26 in the second week to 0.53 in the sixth week of egg production, whereas the ratio of permanent environment to phenotypic variance decreased from 0.48 to 0.1. Direct heritability for EN was low, whereas the ratio of permanent environment to phenotypic variance decreased from 0.57 to 0.15 during the production period. 5. For each trait, estimated genetic correlations among weeks of egg production were high (from 0.85 to 0.98). Genetic correlations between EW and EN were low and negative for the first two weeks, but they were low and positive for the rest of the egg production period. 6. In conclusion, random regression models can be used effectively for analysing egg production traits in Japanese quail. Response to selection for increased egg weight would be higher at older ages because of its higher heritability and such a breeding program would have no negative genetic impact on egg production.

    Hazards of soil-borne Pb to wild birds may be more accurately quantified if the bioavailability of that Pb is known. To better understand the bioavailability of Pb to birds, we measured blood Pb concentrations in Japanese quail (Coturnix japonica) fed diets containing Pb-contaminated soils. Relative bioavailabilities were expressed by comparison with blood Pb concentrations in quail fed a Pb acetate reference diet. Diets containing soil from five Pb-contaminated Superfund sites had relative bioavailabilities from 33%-63%, with a mean of about 50%. Treatment of two of the soils with phosphorus significantly reduced the bioavailability of Pb. Bioaccessibility of Pb in the test soils was then measured in six in vitro tests and regressed on bioavailability. They were: the “Relative Bioavailability Leaching Procedure” (RBALP) at pH 1.5, the same test conducted at pH 2.5, the “Ohio State University In vitro Gastrointestinal” method (OSU IVG), the “Urban Soil Bioaccessible Lead Test”, the modified “Physiologically Based Extraction Test” and the “Waterfowl Physiologically Based Extraction Test.” All regressions had positive slopes. Based on criteria of slope and coefficient of determination, the RBALP pH 2.5 and OSU IVG tests performed very well. Speciation by X-ray absorption spectroscopy demonstrated that, on average, most of the Pb in the sampled soils was sorbed to minerals (30%), bound to organic matter (24%), or present as Pb sulfate (18%). Additional Pb was associated with P (chloropyromorphite, hydroxypyromorphite and tertiary Pb phosphate), and with Pb carbonates, leadhillite (a lead sulfate carbonate hydroxide), and Pb sulfide. The formation of chloropyromorphite reduced the bioavailability of Pb and the amendment of Pb-contaminated soils with P may be a thermodynamically favored means to sequester Pb.

    The main objective of this work was to investigate the impact of dietary chromium supplementation on growth indices, carcass yield, and some hematological and biochemical blood parameters of growing Japanese quails subjected to heat stress. A total of 360 unsexed 2-week-old Japanese quail chicks were used in a 2 × 3 factorial arrangement that had two ambient temperatures (23 ± 2 and 33 ± 2 °C) and three dietary chromium (0.00, 500, and 1000 μg Cr/kg diet as chromium picolinate). For induction of heat stress, the room temperature was set at 33 ± 2 °C from 2 to 6 weeks of age. Results showed that body weight, body weight gain, and feed intake were decreased for birds subjected to heat stress condition during 2 to 4 and 2 to 6 weeks of age. Feed conversion was not significantly (P > 0.05) affected by high ambient temperature throughout the experiment. Carcass, dressing, liver, and heart percentages were not influenced by the ambient temperature or dietary chromium or their combinations. Significant temperature × chromium combinations were observed for hemoglobin value (P = 0.025) and packed cell volume (P = 0.001). Cholesterol and glucose in plasma were increased (P = 0.004 or 0.022) in quails subjected to heat stress condition. Plasma measurements of total proteins, albumin, globulin, lipids, glucose, and A/G ratio of quail chicks were not influenced (P > 0.05) by chromium, while cholesterol was increased with increasing chromium level (P = 0.033). High ambient temperature or dietary chromium levels or their interactions did not (P > 0.05) affect plasma levels of aspartate transaminase (AST), alanine transaminase (ALT), triiodothyronine (T3), thyroxin (T4), or T3/T4 ratio of growing quails. From these observations, it can be concluded that dietary chromium supplementation of growing Japanese quail subjected to heat stress condition could beneficially affect growth performance and carcasses, as well as modulate the hematological

    Full Text Available OBJECTIVE: This study aimed to describe the trade and microbiological quality of boiled quail eggs on the waterfront of Salvador , Bahia, Brazil, from the child labor perspective. METHODS: This cross-sectional study administered semi-structured questionnaires to 40 underage vendors and performed the microbiological assessment of 40 quail egg samples as follows: mesophilic aerobic microorganism count, coagulase-positive staphylococcus count, estimation of the most probable number of total and thermotolerant coliforms/Escherichia coli, and testing for Salmonella spp.. The results were compared with the standards provided by the Resolution RDC nº 12/2001, National Sanitary Surveillance Agency. RESULTS: The vendors were mostly female (57.5% students (95.0% aged 8 to 17 years. The most common reason for working was supplementation of the family income (57.5%. The mean gross income was R$38.31/day. Most of them presented inadequate personal hygiene but they recognized that foods could cause diseases. Many (47.5% vendors reported washing their hands up to twice daily. Mean mesophilic aerobic microorganism and coagulase-positive staphylococcus counts were 2.43 and 2.01 log colony-forming unit/g, respectively, and the estimated thermotolerant coliform contamination was 0.98 log most probable number/g. Escherichia coli was found in 15.0% of the samples and none contained Salmonella spp. Most (55.0% samples were noncompliant with the legislation. CONCLUSION: The results evidenced the presence of minors selling quail eggs on beaches of Salvador and suggest risk to consumers' health because of the detected contamination and vendors' ignorance of principles of hygiene.

    Many birds use grounded running (running without aerial phases) in a wide range of speeds. Contrary to walking and running, numerical investigations of this gait based on the BSLIP (bipedal spring loaded inverted pendulum) template are rare. To obtain template related parameters of quails (e.g. leg stiffness) we used x-ray cinematography combined with ground reaction force measurements of quail grounded running. Interestingly, with speed the quails did not adjust the swing leg's angle of attack with respect to the ground but adapted the angle between legs (which we termed aperture angle), and fixed it about 30ms before touchdown. In simulations with the BSLIP we compared this swing leg alignment policy with the fixed angle of attack with respect to the ground typically used in the literature. We found symmetric periodic grounded running in a simply connected subset comprising one third of the investigated parameter space. The fixed aperture angle strategy revealed improved local stability and surprising tolerance with respect to large perturbations. Starting with the periodic solutions, after step-down step-up or step-up step-down perturbations of 10% leg rest length, in the vast majority of cases the bipedal SLIP could accomplish at least 50 steps to fall. The fixed angle of attack strategy was not feasible. We propose that, in small animals in particular, grounded running may be a common gait that allows highly compliant systems to exploit energy storage without the necessity of quick changes in the locomotor program when facing perturbations. © 2013 Elsevier Ltd.

    Elevated levels of Al have been reported in surface waters and in certain aquatic organisms including aquatic insects in areas receiving acidic precipitation. It has been suggested that Al can affect avian reproduction. In this study, Ring doves were assigned to a control group fed a diet reduced in Ca and P and to a treated group fed the same diet supplemented with 0.1% Al. A four month dosing period did not result in any effect on egg production, fertility or hatchability. Eggshell permeability was decreased initially but subsequently recovered to a normal level. Dietary aluminium suLphate did not affect plasma Ca, P nor Mg levels of adults nor did it affect the pattern of growth nor the final weight of chicks fed on the same diet. There was a tendency for Al to accumulate in the sternum of growing doves fed levels up to 1500 ppm Al. Neither reproduction nor growth of this species were influenced by levels of Al equivalent to those occuring in areas receiving acid deposition. However, the results of a preliminary experiment suggest that decreasing the dietary levels of Ca and P below 0.9% and 0.5% respectively, in combination with excess Al (0.075%) caused significant impacts upon reproduction and growth. Similar experimental findings have been reported in the literature for domestic birds where levels of dietary Al exceeded those of Ca and P. 21 refs.

    In the present study, lipase was immobilized onto two different supports, agarose and gelatin. Some physico-chemical properties of the free and immobilized lipase such as optimum temperature, optimum ph and storage stability were studied. Storage of the enzymes for 2 months showed that the free enzyme lost its activity, while the immobilized on the gelatin showed better resistance towards ph and temperature variations than that immobilized onto agarose. Four experiments were conducted to test the effect of the immobilized lipase supplementation on the productive performance of the Japanese quails. During the first 3 weeks, the addition of lipase to poultry diets caused an increase in the body weight gain of birds than the enzyme-free diet. An obvious improvement in quail day egg production during the laying period was observed with the groups fed on a diet supplemented with 3000 and 2000 I U of immobilized lipase per kilogram feed. Blood cholesterol was not affected with lipase addition, while total lipids were significantly increased. Significant reduction was also observed in thyroid hormones (T 3 and T 4 ) as compared with the control group

    This study examines the effects of operational use of pesticides on avian species inhabiting apple orchards in Pennsylvania. Mourning dove (Zenaida rnacroura) and American robin (Turdus migratorius) nests were monitored in three organic and three conventional apple orchards during 1990 and 1991. In 1991 we surveyed the avian communities of these orchards by using line transects. Organophosphorus (OP) (e.g., azinphos-methyl, phosphamidon, parathion, dimethoate), carbamate (CA) (e.g., methomyl, formetanate, oxamyl), and organochlorine (endosulfan) pesticides, known to be highly toxic to birds, were sprayed individually or in mixtures as part of routine pest management as many as 19 times during peaks in breeding activity. Spray card tests revealed that OP pesticides were deposited on 86% of the nests in conventional orchards. Daily survival rates (DSRs) for nests of both species were higher in the organic orchards than in the conventional orchards for 1991 and for years combined (p the organic orchards (H= 2.43) than in the conventional orchards (H=1.79). Repeated applications of pesticides within the conventional orchards reduced the reproductive success of doves and robins and may have lowered avian species diversity compared with organic orchards.

    The human-caused extinction of the Passenger Pigeon (Ectopistes migratorius) is one of the best known and documented of any bird. This event was particularly alarming because the Passenger Pigeon went from being one of the most numerous avian species in the world to extinct in a period of decades, when the last individual died in captivity in a Cincinnati Zoo in 1914. While a great deal of information exists on the likely direct and indirect causes of its demise, as well as information on life-history, the phylogenetic relationships of this species have been subject to considerable speculation. Here we use DNA sequences obtained from museum specimens to resolve the phylogenetic position of this species with respect to other pigeons and doves (Columbiformes). We show that the Passenger Pigeon is not related to the New World mourning doves (Zenaida) as many authors have suggested, but is the sister taxon of all other New World pigeons (Patagioenas). Biogeographic analysis suggests the Passenger Pigeon lineage may have colonized North America from Asia, and subsequently dispersed into South America, leading to a more extensive radiation of New World pigeons.

    Quail chicks encountered an autonomous mobile robot during their early development. The robot incorporated a heat source that stimulated following of chicks. The spatial behaviour of grown-up chicks was tested in an exploration test and a detour test. Chicks that grew with the mobile robot exhibited better spatial abilities than chicks grown with a static heat source. We discuss these results in the perspective of animal-robot interaction and of the role of early spatial experience on the behavioural development. (communication)

    The present study sought to assess the potential application of avian models with different developmental modes to studies on cognition and neuroscience. Six altricial Bengalese finches (Lonchura striata var. domestica), and eight precocial blue-breasted quails (Coturnix chinensis) were presented with color discrimination tasks to compare their respective faculties for learning and memory retention within the context of the two developmental modes. Tasks consisted of presenting birds with discriminative cues in the form of colored feeder lids, and birds were considered to have learned a task when 80% of their attempts at selecting the correctly colored lid in two consecutive blocks of 10 trials were successful. All of the finches successfully performed the required experimental tasks, whereas only half of the quails were able to execute the same tasks. In the learning test, finches required significantly fewer trials than quails to learn the task (finches: 13.5 ± 9.14 trials, quails: 45.8 ± 4.35 trials, P memory retention tests, which were conducted 45 days after the learning test, finches retained the ability to discriminate between colors correctly (95.0 ± 4.47%), whereas quails did not retain any memory of the experimental procedure and so could not be tested. These results suggested that altricial and precocial birds both possess the faculty for learning and retaining discrimination-type tasks, but that altricial birds perform better than precocial birds in both faculties. The present findings imply that developmental mode is an important consideration for assessing the suitability of bird species for particular experiments. © 2013 Japanese Society of Animal Science.

    Full Text Available In Emily Brontë’s Wuthering Heights, illness and death cause characters to foresee, fear and react to other characters’ deaths. In this article, I explore the significance of Cathy’s anticipatory mourning of, and response to, the eventual actual deaths of her ailing father, Edgar, and her sickly cousin, Linton. Core 19th-century perspectives and fears relating to illness and death are both evident and contested in the representation of Cathy’s anxiety and suffering. I also investigate how Cathy’s grief is exacerbated by and affects the behaviour of other characters, notably Nelly, Linton, Heathcliff, Zillah and Hareton. The depiction of these characters’ responses to Cathy’s misery enriches their portrayal, implying that Cathy’s fear and grief are integral to both the novel’s plot and its character development.

    Two grams of powdered garlic or curcumin or parsley were added separately to each kg of the diet of unsexed Japanese quail aged one day old in an attempt to evaluate growth performance, serum cholesterol, triiodothyronine hormone, small intestine thickness and caecal microbial count to improve meat quality and egg production. The quails were hold in equal 4 groups; each group contained three replicates of 30 birds. Birds were watered and fed ad libitum for 7 weeks then 69 chicks from each group (6 males and 17 females for each replicate) were transferred into laying cages for another 6 weeks while 3 birds from each replicate were slaughtered for serum cholesterol, triiodothyronine, small intestine thickness, microbial count and carcass fatty acid determination. The data revealed that addition of each of the tested herb supplements caused significant increase in body weight, while there was non-significant changes in serum cholesterol, T3, small intestine thickness and total bacterial count. In addition, there was significant increase in unsaturated fatty acids and significant decrease in saturated fatty acids of carcass. The three additives caused remarkable increases in egg production and hatch ability %, besides augmenting the fertility % and number of ovarian follicles. It may be concluded that addition of 2g garlic or curcumin or parsley powder to each kg of the diet of Japanese quail favored consumer expectation in relation to meat quality and egg production and prolonged feed preservation

  1. Comprehensive Identification of Sexual Dimorphism-Associated Differentially Expressed Genes in Two-Way Factorial Designed RNA-Seq Data on Japanese Quail (Coturnix coturnix japonica.

    Kelsey Caetano-Anolles

    Full Text Available Japanese quail (Coturnix coturnix japonica reach sexual maturity earlier, breed rapidly and successfully, and cost less and require less space than other birds raised commercially. Given the value of this species for food production and experimental use, more studies are necessary to determine chromosomal regions and genes associated with gender and breed-differentiation. This study employed Trinity and edgeR for transcriptome analysis of next-generation RNA-seq data, which included 4 tissues obtained from 3 different breeding lines of Japanese quail (random bred control, heavy weight, low weight. Differentially expressed genes shared between female and male tissue contrast groups were analyzed to identify genes related to sexual dimorphism as well as potential novel candidate genes for molecular sexing. Several of the genes identified in the present study as significant sex-related genes have been previously found in avian gene expression analyses (NIPBL, UBAP2, and other genes found differentially expressed in this study and not previously associated with sex-related differences may be considered potential candidates for molecular sexing (TERA, MYP0, PPR17, CASQ2. Additionally, other genes likely associated with neuronal and brain development (CHKA, NYAP, as well as body development and size differentiation (ANKRD26, GRP87 in quail were identified. Expression of homeobox protein regulating genes (HXC4, ISL1 shared between our two sex-related contrast groups (Female Brain vs. Male Brain and Ovary vs. Testis indicates that these genes may regulate sex-specific anatomical development. Results reveal genetic features of the quail breed and could allow for more effective molecular sexing as well as selective breeding for traits important in commercial production.

    Inulin, a group of dietary fibers, is reported to improve the metabolic disorders. In the present study, we investigated the effects of chicory inulin on serum metabolites of uric acid (UA), lipids, glucose, and abdominal fat deposition in quail model induced by a purine-rich diet. In this study, 60 male French quails were randomly allocated to five groups: CON (control group), MOD (model group), BEN (benzbromarone-treated group), CHI-H (high-dosage chicory inulin-treated group), and CHI-L (low-dosage chicory inulin-treated group). The serum UA level was significantly increased in the model group from days 7 to 28, as well as triglyceride (TG) and free fatty acid (FFA) increased later in the experimental period. The abdominal fat ratio was increased on day 28. Benzbromarone can decrease UA levels on days 14 and 28. The high and low dosage of chicory inulin also decreased serum UA levels on days 7, 14, and 28. The abdominal fat ratio, activity, and protein of acetyl-CoA carboxylase (ACC) were decreased in chicory inulin-treated groups. The activities of xanthine oxidase (XOD) and fatty acid synthase (FAS) were increased in the model group and decreased in the benzbromarone and chicory inulin groups. This study evaluated a quail model of induced hyperuricemia with other metabolic disorders caused by a high-purine diet. The results indicated that a purine-rich diet might contribute to the development of hyperuricemia, hypertriglyceridemia, and abdominal obesity. Chicory inulin decreased serum UA, TG, and abdominal fat deposition in a quail model of hyperuricemia by altering the ACC protein expression and FAS and XOD activities.

  3. Bovine meat and Bone Meal as an Economically Viable Alternative in Quail Feeding in the Final Phase

    Full Text Available ABSTRACT Bovine meat and bone meal (MBM has been used as a low-cost protein source in corn- and soybean meal-based poultry diets. However, to date, no studies investigating the effect of the dietary inclusion of MBM on the performance of Japanese quails and on egg production costs were found in literature. In this study, 600 Japanese quails in lay were distributed in a completely randomized experimental design consisting of six treatments (replacement levels of soybean meal by MBM:0, 1, 2, 3, 4, and 5% with five replicates of 20 birds each to investigate if MBM is a viable alternative to maintain or to improve the live and economic performances of these birds. Treatments consisted of a control diet, based on corn and soybean meal, with no inclusion of MBM, and diets formulated with increasing levels (1, 2, 3, 4, and 5% of MBM inclusion at the expense of soybean meal. The studied parameters were evaluated in four periods of 28 days each. Live performance parameters (egg weight, g; average egg production, %; egg weight, g; feed intake, g; feed conversion ratio per egg mass, kg/kg and per dozen eggs, dz/kg; and livability, %; egg quality parameters (proportion of egg components, yolk, albumen, eggshell %; egg specific weight, g/cm3; and economic parameter (bio-economic nutritional index were determined. Only egg weight, egg specific weight, and eggshell percentage were affected (p<0.05 by the treatments. Our results show that inclusion of bovine meat and bone meal can be added to the diet of Japanese quails in lay, causing no performance losses and promoting feed cost savings up to 5.24%.

    Full Text Available Objective Owing to the public availability of complete genome sequences, including avian species, massive bioinformatics analyses may be conducted for computational gene prediction and the identification of gene regulatory networks through various informatics tools. However, to evaluate the biofunctional activity of a predicted target gene, in vivo and in vitro functional genomic analyses should be a prerequisite. Methods Due to a lack of quail genomic sequence information, we first identified the partial genomic structure and sequences of the quail SH3 domain containing ring finger 2 (SH3RF2 gene. Subsequently, SH3RF2 was knocked out using clustered regularly interspaced short palindromic repeat/Cas9 technology and single cell-derived SH3RF2 mutant sublines were established to study the biofunctional activity of SH3RF2 in quail myoblast (QM7 cells during muscle differentiation. Results Through a T7 endonuclease I assay and genotyping analysis, we established an SH3RF2 knockout (KO QM7#4 subline with 61 and 155 nucleotide deletion mutations in SH3RF2. After the induction of myotube differentiation, the expression profiles were analyzed and compared between regular QM7 and SH3RF2 KO QM7#4 cells by global RNA sequencing and bioinformatics analysis. Conclusion We did not detect any statistically significant role of SH3RF2 during myotube differentiation in QM7 myoblast cells. However, additional experiments are necessary to examine the biofunctional activity of SH3RF2 in cell proliferation and muscle growth.

    The potential effects of spaceflight on the processes of mammalian fertilizaton, implantation and embryonic development are investigated. Five female and two male rats were placed together on Day 2 of the flight. By R+17, it was determined that both flight and synchronous females were not carrying normal pregnancies and three of the flight animals were laparotomized. The uterus and ovaries were processed for microscopic analyses. The two remaining flight females were allowed to recover from the exploratory operation, rebred with flight males and delivered normal litters. As a control for potential transplacental effects that might be interpreted as direct spaceflight effects, a series of fertilized Japanese quail (Coturnix japonica) eggs was flown on Cosmos 1129. Although all of the eggs were adversely impacted by an inflight failure of the incubator humidifier on flight Day 13, several embryos were able to progress to a developmental stage equivalent to that of a control 10-12 Day embryo.

    In February 2015, two Eurasian collared doves (Streptopelia decaocto) were submitted dead to the California Animal Health and Food Safety (CAHFS) Laboratory, Turlock branch, from a private aviary experiencing sudden, high mortality (4/9) in adult doves. In both doves, the gross and histologic lesions were indicative of acute, fatal septicemia. Grossly, there were numerous pale yellow foci, 1 to 2 mm in diameter, in the liver and spleen. Microscopically, these foci were composed of acute severe multifocal coagulative necrosis of hepatocytes and splenic pulp with infiltration of heterophils mixed with fibrin and dense colonies of gram-negative bacteria. Yersinia pseudotuberculosis was isolated from the lung, liver, spleen, heart, ovary, kidney, and trachea. The organism was susceptible to most antibiotics it was tested against, except erythromycin. Based on a retrospective study of necropsy submissions to CAHFS between 1990 and 2015, there were 77 avian case submissions of Y. pseudotuberculosis. There were 75/77 cases identified from a wide range of captive avian species from both zoo and private facilities and 2/77 cases from two backyard turkeys submitted from one premise. The largest number of cases originated from psittacine species (31/77). The lesions most commonly described were hepatitis (63/77), splenitis (49/77), pneumonia (30/77), nephritis (16/77), and enteritis (12/77). From 1990 to 2015, there was an average of three cases of avian pseudotuberculosis per year at CAHFS. Although there were no cases diagnosed in 1993 and 1994, in all other years, there were between one and eight cases of Y. pseudotuberculosis detected from avian diagnostic submissions.

    Full Text Available In this article I examine how death and loss feature in recent apocalypse fiction and suggest that, in a genre mostly concerned with finitude, there appears to be paradoxically little room for expressions of mourning. I assess contemporary attitudes towards mortality through the writings of Philippe Ariès, Zygmunt Bauman, Simon Critchley and others, and propose a psychoanalytic reading of solitary survivor narrative, inspired by the work of Martin Jay. In the final part of the article, I turn to Sigmund Freud and René Girard to explore the relation between apocalyptic teleology, melancholy, and the expectation of global catastrophe.   Narcisismo apocalittico e la difficoltà del lutto In questo articolo indago la rappresentazione della morte e della perdita nella recente letteratura apocalittica, e avanzo l’ipotesi che in un genere letterario ossessionato dall’idea di fine sembra esserci poco spazio, paradossalmente, per l’espressione del lutto. Traendo esempi da Philippe Ariès, Zygmunt Bauman, Simon Critchley, ricostruisco alcuni atteggiamenti davanti la morte che dominano il dibattito filosofico contemporaneo, e, sulla scia di Martin Jay, propongo una lettura psicoanalitica delle narrazioni dell’ultimo uomo. Nella parte finale dell’articolo, traggo spunto dalle intuizioni di Sigmund Freud e René Girard per esplorare il rapporto tra teleologia apocalittica, malinconia, e aspettative di una catastrofe globale.

    Nucleoli are the product of nucleolus organizing region activity (NOR) of specific chromosomes. Their basic function is to synthetise ribosomal RNA precursors and promote the maturation and assemblage of preribosomal RNP molecules. Information on rRNA-coding gene activity can be provided by the analysis of the number and size of nucleoli in the prophase of the first meiotic division. The morphology and ultrastructure of a nucleolus depends, among others, on the species and cell growth cycle as well as the physiological and pathological state of an organism. The purpose of this research was to determine the number and size of nucleoli in the spermatocytes of the domestic chicken and the Japanese quail. Diverse numbers and sizes of nucleoli in the cells of the analysed birds were observed. 1-4 nucleoli were identified in chicken cells (1.91 +/- 0.63 on average) and 1-2 in quail cells (1.13 +/- 0.33 on average). For the total of 957 nucleoli observed in Gallus cells, 329 were classified as large and 628 as small. In Coturnix cells, 563 nucleoli were identified (66 large and 497 small ones). An analysis of the numbers and sizes of nucleoli can be performed at the cytogenetic level and serve as an alternative source of information on rRNA encoding gene and nucleolus organising region (NOR) activities.

    Full Text Available This study was conducted to evaluate the effects of replacing maize in quail diets with graded levels of rumen filtrate-fermented cassava meal (FCM on growth and egg production performances. Cassava meal (CM was mixed with dried manure of layer at 75 g/kg CM, which was mixed with freshly collected rumen filtrate (at 1 L/5 kg CM, and finally fermented in sealed bags for 14 days. It was then sun-dried and added in grower or finisher diets at 0, 50, 75 and 100%. Then, 84 three weeks-old Japanese quails (Cortunix japonica were divided into four equal groups; the birds were randomly assigned to 0, 50, 75 and 100% FCM grower/layers diets, and were reared until 56 days of age. Daily feed consumption, weekly body weights, weight gains, feed conversion ratios (FCR, hen-day, and egg weights were monitored. The quails fed with 75% FCM were found to be superior (p0.05 effect on feed intake, body weight, and weight gain, as compared to those of fed control diets. Thus, replacing maize with FCM had no deleterious effects on growth performance, but depressed hen-day. However, better growth performance was obtained when maize was replaced at 75% FCM.

    Erectile dysfunction is a common side-effect of prostate cancer surgery that causes men suffering and hinders their sexual recovery. There are studies that describe men's and partners' distress and couples' difficulties engaging in sexual recovery. A few studies show a short-term benefit of brief psycho-social interventions such as psychoeducation and counseling. However, there is no conceptual framework to guide psychosocial treatments. We propose a model of intervention in sexual recovery that incorporates grief and mourning as a gateway to new and satisfying sexuality after prostate cancer treatment.

  11. The Violence of Post-Racial Memory and the Political Sense of Mourning

    Full Text Available In this paper I argue that “post-raciality” entails a way of remembering that depoliticizes the social meaning of memory and thus of history. Through aesthetic critique, I attempt to show how the hyper-production of memory obscures the very real forms of violence directed toward non-whites. By developing the aesthetic critiques of W.E.B. Du Bois and Walter Benjamin, I argue that representing former violence as social memory fails to adequately address subtle forms of cultural and residual violence. Furthermore, I argue that post-racial memory produces sites and representations of the past only to enact a type of social forgetting in the present. I develop a political sense of mourning as a form of resistance against the violence of post-racial memory.

    Full Text Available Our previous results showed that kisspeptin-10 (Kp-10 injections via intraperitoneal (i.p. once daily for three weeks notably promoted the egg laying rate in quails. In order to investigate the mechanism behind the effects of Kp-10 on enhancing the egg laying rate in birds, this study focused on the alternations of lipids synthesis in liver after Kp-10 injections. 75 female quails (22 d of age were allocated to three groups randomly, and subjected to 0 (control, Con, 10 nmol (low dosage, L and 100 nmol (high dosage, H Kp-10 injections via i.p. once daily for three weeks, respectively. At d 52, quails were sacrificed and sampled for further analyses. Serum E2 concentration was increased by Kp-10 injections, and reached statistical significance in H group. Serum triglyceride (TG concentrations were increased by 46.7% in L group and 36.8% in H group, respectively, but did not reach statistical significance, and TG contents in liver were significantly elevated by Kp-10 injections in a dose-dependent manner. Serum total cholesterol (Tch concentrations significantly decreased in H group, while in H group the hepatic Tch content was markedly increased. The level of non-esterified fatty acid (NEFA, apolipoprotein A1 and B (apoA1 and apoB were not altered by Kp-10 injections. The genes expression of sterol regulatory element binding protein-1 (SREBP-1, fatty acid synthetase (FAS, apolipoprotein VLDL-II (apoVLDL-II, cholesterol 7α-hydroxylase (CYP7A1 and vitellogenin II (VTG-II were significantly up-regulated by high but not low dosage of Kp-10 injection compared to the control group.

    The generation of germline chimeras by the transfer of primordial germ cells (PGCs) requires incorporation of the PGCs of the donor into the gonadal tissue of the recipient embryo. We investigated the utility of soft x-irradiation with application of a lead (12 x 3 x 0.25 mm, - 0.1 g) shield to the embryo proper for the production of chicken-quail germline chimeras. Chicken embryos shielded during irradiation for 120s (- 7.2 Gy) at stages 13 to 17 showed a hatchability of 35% (106/301), whereas the hatchability of unshielded embryos was 26% (27/105). The relative population of gonadal PGCs at stage 30 for embryos irradiated at stage 13 with or without shielding was 13 and 5%, respectively, of the value for nonirradiated controls. Chicken embryos irradiated at stages 13 or 14 with or without shielding and transfused with quail embryonic blood containing PGCs each exhibited - 130 relative population of donor PGCs in the left gonad at stage 30. Xenotransplanted hatchlings exhibited donor-derived PGCs as detected by Southern hybridization and PCR. Exposure of chicken embryos to - 7.2 Gy of x-radiation at stage 13 with the application of a lead shield to the embryo proper is thus a feasible approach to depletion of endogenous germ cells and the production of chicken-quail germline chimeras

  14. Inhibition of lipolysis in the novel transgenic quail model overexpressing G0/G1 switch gene 2 in the adipose tissue during feed restriction.

    Full Text Available In addition to the issue of obesity in humans, the production of low-fat meat from domestic animals is important in the agricultural industry to satisfy consumer demand. Understanding the regulation of lipolysis in adipose tissue could advance our knowledge to potentially solve both issues. Although the G0/G1 switch gene 2 (G0S2 was recently identified as an inhibitor of adipose triglyceride lipase (ATGL in vitro, its role in vivo has not been fully clarified. This study was conducted to investigate the role of G0S2 gene in vivo by using two independent transgenic quail lines during different energy conditions. Unexpectedly, G0S2 overexpression had a negligible effect on plasma NEFA concentration, fat cell size and fat pad weight under ad libitum feeding condition when adipose lipolytic activity is minimal. A two-week feed restriction in non-transgenic quail expectedly caused increased plasma NEFA concentration and dramatically reduced fat cell size and fat pad weight. Contrary, G0S2 overexpression under a feed restriction resulted in a significantly less elevation of plasma NEFA concentration and smaller reductions in fat pad weights and fat cell size compared to non-transgenic quail, demonstrating inhibition of lipolysis and resistance to loss of fat by G0S2. Excessive G0S2 inhibits lipolysis in vivo during active lipolytic conditions, such as food restriction and fasting, suggesting G0S2 as a potential target for treatment of obesity. In addition, transgenic quail are novel models for studying lipid metabolism and mechanisms of obesity.

    2012-06-01

    Complicated grief is a recently recognized condition that occurs in about 7% of bereaved people. People with this condition are caught up in rumination about the circumstances of the death, worry about its consequences, or excessive avoidance of reminders of the loss. Unable to comprehend the finality and consequences of the loss, they resort to excessive avoidance of reminders of the loss as they are tossed helplessly on waves of intense emotion. People with complicated grief need help, and clinicians need to know how to recognize the symptoms and how to provide help. This paper provides a framework to help clinicans understand bereavement, grief, and mourning. Evidence-based diagnostic criteria are provided to help clinicians recognize complicated grief, and differentiate it from depression as well as anxiety disorder. We provide an overview of risk factors and basic assumptions and principles that can guide treatment.

    Full Text Available An indirect ELISA for the detection of japanese quail IgG specific to Newcastle disease virus (NDV was developed. The secondary anti-quail IgG was produced in Balb/c mice, by inoculating Freund's complete adjuvant emulsified japanese quail-IgG extract. The purification of IgG was achieved using the caprilic acid method. The ELISA was compared to the haemagglutination-inhibition (HI test for antibodies to NDV. ELISA cut-off point was established through TG-ROC analysis. Total correlation was observed between the ELISA and the HI, being the ELISA efficient in the identification of positive and negative sera, with high sensitivity and specificity (100%. These results validate the use of the indirect ELISA as an alternative for the detection of NDV-specific IgG in japanese quail sera, with the advantage of high sensitivity and automation.

    Full Text Available The CaO solid derived from natural quail eggshell was calcined and employed as catalyst to produce biodiesel via transesterification of sunflower oil. The natural quail eggshell was calcined at 900°C for 3 h, in order to modify the calcium carbonate present in its structure in CaO, the activity phase of the catalyst. Both precursor and catalyst were characterized using Hammett indicators method, X-ray fluorescence (XRF, X-ray diffraction (XRD, thermogravimetric analysis (TG/DTG, CO2 temperature-programmed desorption (CO2-TPD, X-ray photoelectronic spectroscopy (XPS, Fourier infrared spectroscopy (FTIR, scanning electron microscopy (SEM, N2 adsorption-desorption at −196°C, and distribution particle size. The maximum biodiesel production was of 99.00 ± 0.02 wt.% obtained in the following transesterification reaction conditions: XMR (sunflower oil/methanol molar ratio of 1 : 10.5 mol : mol, XCAT (catalyst loading of 2 wt.%, XTIME (reaction time of 2 h, stirring rate of 1000 rpm, and temperature of 60°C.

We studied 896 meatquails. The experimental design was completely randomized with a 4x4 factorial arrangement, using four types of shedroofs (fiber cement, ceramic, straw, and painted fiber cement and four rations (with 0, 5, 10, and 15% inclusion of babassu pie. The performance variables evaluated from 14 to 28 and 14 to 40 days included food intake (FI, g/bird, mean weight gain (WG, g/bird, food conversion (FC, g/g, mean live weight on day 28 (MW28, g/bird, mean live weight on day 40 (MW40, g/bird, and energy efficiency (EF; g Mcal. After slautherthe birds on day 40, we measured the carcass weight (CW and the carcass yield (CY, %, obtained for the breast (BY, legs (LGY, and wings (WINGY. We also obtained the relative weight of the heart (HRW, liver (LRW, gizzard (GRW, and intestine (IRW. To compare the economic efficiency between the experimental rations, we analyzed the cost of ration per kg of carcass (CC and determined the gross margin (GM. Between day 14 and day 28, we found that the use of SR influenced the FI28, WG28, and the MW28 of the quails (p 0.05, but it linearly improved WG28, FC28, MW28, and EF28. Between days 14 and 40, we found that SR influenced the WG40, FC40, MW40, and EF40 of the quails (p < 0.05 and that a BP increased the FI40, WG40, and MW40 in a quadratic manner. SR and BP did not affect the CW, BY, WINGY, LGY, HRW, LRW,or IRW. However, BP influenced MGRW, which increased linearly with the inclusion of BP. We concluded that a ceramic roof provides better environmental conditions than do other shed roofs. The inclusion of BP improved the performance characteristics, and it was technically feasible to include up to 15% BP in the rations of meat quails. Based on the current cost analysis, however, the inclusion of BP is economically

    The radioiodination of ochratoxin using iodogen as an oxidizing agent was studied. The factors affecting the radioiodination yield, such as reaction time, concentration of substrate and oxidizing agent, pH, stability of iodogen coated tubes have been investigated. Separation and purification of the labelled product using thin layer chromatography and gel chromatography on sephadex G-25 column were described.A total number of 80 quail chicks at eight weeks age were divided into two groups 40 birds each. The first group (control) feed basal diet and the second group was supplemented with 0.5% active dried yeast (Saccharomyces cerevisiae) in basal diet. All groups were given orally labelled ochratoxin. After 6, 12, 24 and 48 hours from oral feeding, the quails (5 birds from every group) were slaughtered and blood samples were collected when slaughtering. The organs; liver, heart, spleen lung, proventriculus, gizzard, intestine content, kidney, testis, ovary, oviduct, breast and thigh, were removed and weighed individually and their weights related to body weight have been calculated. Also, manure and eggs were collected. The radioactivity levels in the second group that supplemented yeast in diet was lower than the first group (control) except manure

  3. Interactions between aromatase (estrogen synthase) and dopamine in the control of male sexual behavior in quail.

    2002-05-01

    In male quail, like in other vertebrates including rodents, testosterone acting especially through its estrogenic metabolites is necessary for the activation of male sexual behavior. Also, the administration of dopamine agonists and antagonists profoundly influences male sexual behavior. How the steroid-sensitive neural network and dopamine interact physiologically, remains largely unknown. It is often implicitly assumed that testosterone or its metabolite estradiol, stimulates male sexual behavior via the modification of dopaminergic transmission. We have now identified in quail two possible ways in which dopamine could potentially affect sexual behavior by modulating the aromatization of testosterone into an estrogen. One is a long-acting mechanism that presumably involves the modification of dopaminergic transmission followed by the alteration of the genomic expression of aromatase. The other is a more rapid mechanism that does not appear to be dopamine receptor-mediated and may involve a direct interaction of dopamine with aromatase (possibly via substrate competition). We review here the experimental data supporting the existence of these controls of aromatase activity by dopamine and discuss the possible contribution of these controls to the activation of male sexual behavior.

    A total number of 1400 one-day old Japanese quail birds were used in this study, the birds were divided into seven equal groups, six treated while the 7 t h served as the control. The diet of the six treated groups was supplemented with 8 % of either one of the following tested oils: soybean (SBO), sunflower (SFO), corn (CO), cottonseed (CSO), olive (OO) or palm (PO). At the end of the 4 t hand 8 t h weeks of age blood samples were collected for blood picture, proteins and cortisol determination. Antibody titer against sheep red blood cells (SRBCs) and NewCastle disease virus (NDV) were determined at 7 and 8 weeks of age respectively. The results showed significant increase in relative lymphoid organ weights, RBCs, WBCs, Hb and PCV, total protein, globulin and cortisol hormone in treated groups compared to the control. The immunological parameters showed a significant increase in (HA) and (HI) against (SRBCs) and (NDV), respectively, in all treated groups compared to the control group. The present results confirm the beneficial effects of dietary oil supplementation to quail birds and in particular olive oil.

  5. Evidence of expanded host range and mammalian-associated genetic changes in a duck H9N2 influenza virus following adaptation in quail and chickens.

    Directory of Open Access Journals (Sweden)

    Md Jaber Hossain

    Full Text Available H9N2 avian influenza viruses continue to circulate worldwide; in Asia, H9N2 viruses have caused disease outbreaks and established lineages in land-based poultry. Some H9N2 strains are considered potentially pandemic because they have infected humans causing mild respiratory disease. In addition, some of these H9N2 strains replicate efficiently in mice without prior adaptation suggesting that H9N2 strains are expanding their host range. In order to understand the molecular basis of the interspecies transmission of H9N2 viruses, we adapted in the laboratory a wildtype duck H9N2 virus, influenza A/duck/Hong Kong/702/79 (WT702 virus, in quail and chickens through serial lung passages. We carried out comparative analysis of the replication and transmission in quail and chickens of WT702 and the viruses obtained after 23 serial passages in quail (QA23 followed by 10 serial passages in chickens (QA23CkA10. Although the WT702 virus can replicate and transmit in quail, it replicates poorly and does not transmit in chickens. In contrast, the QA23CkA10 virus was very efficient at replicating and transmitting in quail and chickens. Nucleotide sequence analysis of the QA23 and QA23CkA10 viruses compared to the WT702 virus indicated several nucleotide substitutions resulting in amino acid changes within the surface and internal proteins. In addition, a 21-amino acid deletion was found in the stalk of the NA protein of the QA23 virus and was maintained without further modification in the QA23CkA10 adapted virus. More importantly, both the QA23 and the QA23CkA10 viruses, unlike the WT702 virus, were able to readily infect mice, produce a large-plaque phenotype, showed faster replication kinetics in tissue culture, and resulted in the quick selection of the K627 amino acid mammalian-associated signature in PB2. These results are in agreement with the notion that adaptation of H9 viruses to land-based birds can lead to strains with expanded host range.

    Chromium picolinate is used in the poultry diet because of its antistress effects in addition to the fact that the requirement for it is increased during stress. This study was conducted to determine if the negative effects of high ambient temperature (34 degrees C) on egg production, egg quality, antioxidant status, and cholesterol and mineral content of egg yolk could be alleviated by combination of chromium picolinate and biotin (0.6/2.0; Diachrome, as formulated by Nutrition 21 Inc.), in laying Japanese quails (Coturnix coturnix japanica). Quails (n= 240; 50 d old) were divided into 8 groups, 30 birds per group. The quails were fed either a basal diet or the basal diet supplemented with 2, 4, or 8 mg of Diachrome/kg diet. Birds were kept at 22 degrees C and 53% relative humidity (RH). At 14 wk of age, the thermoneutral (TN) group remained in the same temperature as at the beginning of experiment, whereas the heat stress (HS) group was kept in an environment-controlled room (34 degrees C and 41% RH) for 3 wk. Heat exposure decreased performance when the basal diet was fed (p = 0.001). Diachrome supplementation at 4 and 8 mg/kg diet, increased feed intake (p = 0.05), egg production (p = 0.05), feed efficiency (p = 0.01), egg weight (p = 0.05), and Haugh unit (p = 0.01) in quails reared under heat stress conditions. Heat exposure increased concentrations of serum malondialdehyde (MDA) (p = 0.001), glucose, and cholesterol (p = 0.01), which were elevated by supplemental Diachrome (p < or = 0.05). Egg yolk Cr, Zn, and Fe (p = 0.01) concentrations increased linearly, whereas MDA and cholesterol concentrations decreased (p = 0.05) as dietary Diachrome supplementation increased in HS groups. Similar effects of supplementation on serum levels of glucose and cholesterol (p = 0.05) and egg yolk concentrations of cholesterol (p = 0.05) and Cr (p = 0.01) were observed in TN groups. No significant differences in other values were observed in the TN groups. Results of the

  7. The Chiasmus of Mourning and Identification in Jean Genet

    Peter Benson

    2000-06-01

    Full Text Available The theories of psychological identification proposed by Sigmund Freud and Kaja Silverman are explored in relation to Jean Genet's Funeral Rites and his later essay on Rembrandt. Genet can be seen to separate mourning (which for Freud lies at the basis of identification from a process of generalized identification in which his difference from other people dissolves. A narcissistic formation of personality, evident in the symbolism of mirrors in Funeral Rites , gives to this process an added impetus. But the fundamental condition of possibility for such generalized identification is the void it reveals at the center of all personality. This void not only makes possible the different kinds of identification (heteropathic and idiopathic described by Silverman, it also disturbs any clear distinction between them. It is for these reasons that the glamorization of Nazism in Funeral Rites is coextensive with a demystification of its power, and the often brutal eroticism of the book is suffused with an ineradicable dimension of tenderness. Taken further in the essay on Rembrandt, these themes lead to an ambiguous mysticism in which the source of creativity is revealed as inseparable from its ultimate obliteration.

    CLN Ribeiro

    Full Text Available ABSTRACT Calcium (Ca and available phosphorus (avP requirements for egg production are different between the beginning and the end of the egg-production cycle. The objective of this study was to estimate the Ca and avP requirements of Japanese quails at end of the production phase. In total, 256 Japanese quails with 48 weeks of age were randomly distributed in 2 x 2 factorial arrangement consisting of two Ca levels (29 and 38 g/kg and two avP levels (1.5 and 3.0 g/kg, totaling four treatments with eight replicates of eight hens each. The variables evaluated were feed intake (FI; egg production (EP; marketable egg production (MEP; egg weight (EW; egg mass (EM; feed conversion ratio per egg mass (FCRM; feed conversion ratio per dozen eggs (FCRD; livability (L; yolk weight (YW, albumen weight (AW, eggshell weight (SW; yolk percentage (YP, albumen percentage (AP, eggshell percentage (SP, specific egg weight (SEW; bone calcium percentage (BCa, bone phosphorus percentage (BP, bone ash weight (Bash and bone ash percentage (PBash. There was no interaction between Ca and avP levels for any of the evaluated parameters, except for SEW. Quail performance was not influenced by the treatments, except for MEP. Bone characteristics were not influenced by the tested dietary Ca and avP levels. However, SW and SP increased and AP decreased as dietary Ca level increased. The dietary supplementation of 38 g Ca/kg and 3.0 g avP/kg may increase marketable egg production and the egg quality of Japanese quails at end of the production cycle.

    Full Text Available ABSTRACT The objective of this study was to determine the effect of dietary symbiotic supplementation on the growth performance and duodenum histological parameters of quail reared in different flooring systems. A total of 160 mixed-sex healthy quail (47±0.32 g aged 14 days were used in a 2 × 2 factorial experimental design with four replicates, each including five males and five females. Two flooring systems (wire floor as control and wood shavings bedding and two dietary treatments (symbiotic supplementation and no supplementation were tested. Birds were transferred to four-tier cages for the trial. Each kilogram of the commercial diet included 224 g crude protein and 3,080 kcal metabolizable energy. The experiment lasted 21 days. Daily weight gain and gastrointestinal tract weight were statistically higher in the wood shavings and wood shavings + symbiotic-supplemented groups than in control group. Villi length was higher in the wood shavings + symbiotic and symbiotic-supplemented groups than in control and wood shavings groups. The wood shavings groups had longer villi than control group. Villi width was higher in wood shaving + symbiotic-supplemented groups compared with the other treatment groups. The litter system of wood shavings and symbiotic supplementation provide better growth performance to quail by developing their duodenum histomorphological parameters and digestive tract.

Male Japanese quails (n=120), arranged into four groups each of three replicates, were supplemented with BO at 1%, 2% and 4% at the expense of 4% cotton seed oil (CSO). At the end of the experiment (10 weeks), three birds from each replicate were slaughtered and serum, small intestine and liver were collected for the determination of total testosterone, total protein, albumin and globulin fractions and fat studying the histology of small intestine and liver. The data revealed that feeding with BO led to decrease of total proteins and β-globulins in addition to cellular damages of small intestine and liver. This effect was increased with increasing the BO concentration in the diet

    It has been established that 3.3',5-triiodothyronine (T 3 ) acts hipermetabolically, whereas 3'3.5'-triiodothyronine (reverse T 3 , rT 3 ) acts hypometabolically. The normal ratio of T 3 to rT 3 in domestic flows fluctuates around 10. Since the excess of T 3 may promote catabolic processes and lower weight gain, the aim of this experiment was to find the optimal ratio of T 3 :rT 3 in blood plasma which corresponds with the greatest weight gain in Japanese quail. Reverse T 3 was given in drinking water (1 μg rT 3 /ml) for 3, 10, 20 or 30 days. It has been found that T 3 /rT 3 ratio of about 5, after 20 days of rT 3 administration, stimulated the weight gain of Japanese quail of both sexes from 7 to 44% with more pronounced effect in female birds.

    Enriched uranium, 93.16% for 235 U, served as a tracer of uranium deposition in an avian species, the Japanese quail. A second label, 153 Gd, provided for monitoring of procedures and for estimation of the 235 U content of live eggs. Depositions of 235 U were greater than for 153 Gd in all tissues except the yolk sac and the liver. Skeletal levels for 235 U were age- and sex-dependent. Feathers contained only 0.11% of the 235 U tracer in contrast to 50% of the endogenous uranium. The results show that 235 U provides for tracing uranium metabolism in small animals, since in quail the tracer increased the uranium burden of the body by only 1-8%. (author)

    Full Text Available The biochemical indexes “glycogen in liver” and “ketones in blood” of 0-72 hours feed deprived (according to methods for balanced experiments Japanese quails with and without energy additives were determined. There were 2 groups of birds- 1-st without energy supplement, 2-nd- fed with 1 g. glucose per os (as 25% solution – twice in 24 hours. The levels of liver glycogen in all the food-deprived quails were signifi cantly lower from -6910 (12-th hour of starving-to 4960mg/kg (72 hour of starving compared to the levels of the same index in fed birds (11990 mg/kg tissue. In the birds receiving energy additive they were higher compared to those deprived of the additive throughout the experimental period. The content of ketones in blood of the control birds was 0.015 mmol/l. The same index increased to 0.027 mmol/l in the feed and energy additive deprived group after the 36 hour of starving, but in the group became energy support, the contents of ketones were lower for the whole period of starving. The energy additive (1g glucose/24 hours helped the maintenance of the energy metabolism during continuous food depriving of the experimental quails.

    The effects of increasing levels of soybean acid oil in diets of quails on the quality of eggs were evaluated over a period of 56 days. A completely randomized design with five treatment levels of soybean acid oil (0, 2, 4, 6, and 8%) as a replacer for soybean oil and eight replicates of two quails each were used. A total of 240 fresh eggs were used for quality analysis, and 400 eggs were stored at 23ºC over a period of 0, 7, 14, 21, and 28 days for analysis of shelf-life. Polynomial regression and ANOVA with repeated measurements and Tukey´s tests were used. Soybean acid oil linearly increased the intensity of red (a* = -5.26 + 0.14 x, R2 = 0.89, P = 0.01) and yellow (b* = 42.32 + 0.44 x, R2 = 0.88 P = 0.01). All other variables of egg quality were not affected by the treatments, with the exception of sensory attributes, such as odor and aftertaste, which were more pronounced with soybean acid oil. In conclusion, soybean acid oil affects the intensity of yellow and red color of the yolk. Trained assessors detected differences in odor and aftertaste of eggs when soybean acid oil was included in the quail diet.

    Full Text Available Two Japanese quail strains, respectively atherosclerosis-susceptible (SUS and –resistant (RES, have been shown to be good models to study cholesterol metabolism and transportation associated with atherosclerosis. Our objective was to examine possible difference in cecal microbiota between these strains when fed a control diet and a cholesterol enriched diet, to determine how host genotype and diet could affect the cecal microbiome that may play a part in cholesterol metabolism. A factorial study with both strains and two diets (control, cholesterol was carried out. Cecal content was collected from 12 week old quail that have been on their respective diets for 6 weeks. DNA was extracted from the samples and the variable region 3 to 5 of the bacterial 16S rRNA gene was amplified. The amplicon libraries were subjected to pyrosequencing. Principal Component Analysis (PCA of β-diversity showed four distinct microbiota communities that can be assigned to the 4 treatment groups (RES/control, RES/cholesterol, SUS/control, SUS/cholesterol. At the Phylum level, the 4 treatment groups has distinct Firmicutes community characteristics but no significant difference in Bacteroidetes. Eubacterium dolichum was rare in RES/control but became overabundant in RES/cholesterol. An unclassified species of Lactobacillaceae was found in abundance in SUS/control but the same species was rare in RES/cholesterol. On the other hand, two Lactobacillus species were only found in RES/control and an unclassified Lachnospiraceae species was abundant in RES/cholesterol but rare in SUS/control. The abundance of 4 species of Lachnospiraceae, 3 species of Ruminococcaceae and one species of Coprobacillaceae was positively correlated with plasma Total Cholesterol, plasma LDL, and LDL/HDL ratio. Our study of cecal microbiota in these quail has demonstrated that selection for susceptibility/resistance to diet induced atherosclerosis has also affected the quail’s cecal environment

    Full Text Available Abstract Background SNP (Single Nucleotide Polymorphism discovery is now routinely performed using high-throughput sequencing of reduced representation libraries. Our objective was to adapt 454 GS FLX based sequencing methodologies in order to obtain the largest possible dataset from two reduced representations libraries, produced by AFLP (Amplified Fragment Length Polymorphism for genomic DNA, and EST (Expressed Sequence Tag for the transcribed fraction of the genome. Findings The expressed fraction was obtained by preparing cDNA libraries without PCR amplification from quail embryo and brain. To optimize the information content for SNP analyses, libraries were prepared from individuals selected in three quail lines and each individual in the AFLP library was tagged. Sequencing runs produced 399,189 sequence reads from cDNA and 373,484 from genomic fragments, covering close to 250 Mb of sequence in total. Conclusions Both methods used to obtain reduced representations for high-throughput sequencing were successful after several improvements. The protocols may be used for several sequencing applications, such as de novo sequencing, tagged PCR fragments or long fragment sequencing of cDNA.

    Full Text Available Known as "domestic dove", the Columba livia (Gmelin, 1789 is a columbidae species widely distributed in Brazil, whose reproductive biology has been studied by many researchers. The testes of 12 Columba livia males were collected and prepared for histologic examination under an optical microscope, the results of which were analysed and photographed. The tunica albuginea that covers the testes consists of a thick, not very cellular layer of dense connective tissue. Groups of interstitial cells with typical morphological appearance and surrounded by loose, well vascularized connective tissue are observable within the organ, between the seminiferous tubules. The seminiferous tubules are thick, intensely wound and, when seen in cross section, show Sertoli cells and spermatogenic lineage cells in different stages of development. These include spermatogonia (type A, clear; type A, dark; and type B, spermatocytes I and II, spermatids, and a large number of spermatozoons. Similarities are found between the histological findings described and those reported for the testes of Columbina talpacoti (Temminck, 1811.

    In this study, the influence of hyperthyroidism and hypothyroidism on the egg quality in 5 week-female Japanese quails was investigated. Hyperthyroidsm and hypothyroidism were achieved by mixing 0.4 mg/100 g. levatrocsyn-sodium and % 0.2 g. propylthiouracil (PTU) in to the food during the 5 weeks period, respectively. It was found that egg weight, albumen weight, shell weight and shell thickness values in both trial groups reduced (P

    Auditory or visual hallucinations of a deceased person are well known in the normal course of the bereavement process. According to DSM-5, this symptom is included in the associated features supporting diagnosis of persistent complex bereavement disorder. In Japan, however, little is known about these hallucinatory experiences during grieving, and few reports on their prevalence are available. Here, we have reported a clinical case of such experiences following the loss of a spouse. A 66-year-old patient presented to the outpatient department with insomnia after her husband's death. She was preoccupied with a sense of loss and absolute loneliness. One day, she confessed to regularly encountering her husband's ghost at night; the ghost was distinguishable from a dream and provided the bereaved wife with some degree of comfort. The appearances lasted for 15 months and occurred several times a week without disturbing her social functioning. She gradually became aware that her husband was returning from the spirit world to give her solace. Her treatment was focused on resolving her conflicting feelings concerning her grief at his death and her relief at his no longer suffering from disease. While accepting her experiences, she started to review the days they spent together and appreciated his attachment. Therefore she completed the work of mourning and the ghost no longer appeared. One year after the departure of the ghost, she still attends the hospital regularly and there has been no recurrence. A reconstruction of her internal world leads us to conclude that the support of normal grief with such hallucinations prevents the intense experience of loss from generating pathological grief. Furthermore, we suggest reconsidering the importance of the mourning work and the inclusion of both the bereaved and deceased person in the medical context.

    Although there are in vivo assays using various organisms for the risk assessment of chemicals with endocrine disrupting properties, effective experimental methods for avian species are still under debate. We have developed an in ovo exposure assay using Japanese quail eggs, aimed at assessing disrupting effects on avian reproductive development and function. Hybrid eggs from Brazilian Brown male and White Egg female quails, which can be genetically sexed by their plumage color after hatching, were prepared, and test materials dissolved in olive oil were injected into the air-chamber on day 10 of incubation. After sexual maturation of hatched chicks, we observed egg production by females and the egg quality and male-typical reproductive behavior, and then examined reproductive system morphology and serum steroid concentrations in both sexes. Treatment with a synthetic estrogen, diethylstilbestrol (DES, 0.5-50 ng/g egg), dose-dependently reduced the eggshell thickness and strength of eggs. A few females treated with 5 ng/g DES per egg produced soft-shelled/ unmarked eggs, and all laying females treated with 50 ng/g egg produced eggs completely lacking shells. DES also induced shortening of the left oviduct and abnormal development of the right oviduct in a dose-dependent manner, while testis weight was reduced symmetrically. In addition, 2,2',4',6'-tetrachlorobiphenyl-4-ol (10-1,000 ng/g egg), which previously showed relatively high estrogenic activity in vitro, caused dose-dependent shortening of the left oviduct and reduction in testis weight. The methods for evaluating endocrine disrupting effects and preparing experimental birds proposed in the present study are expected to facilitate assays for avian reproductive toxicology.

    Full Text Available In the present study Salmonella spp. was surveyed in four flocks of meat-type quails reared in a farm that also had processing plant on site, located in the region of Bastos, state of São Paulo, Brazil. Meconium samples of one-day-old quail chicks were collected from transport cardboard boxes. Cecal content was collected on days 7, 14, 21, 28 and 35 of rearing. At 36 days of age, birds were slaughtered in the farm's processing plant, where two samples of water from the scalding and the chilling tanks and four carcasses per flock were collected. All samples were examined for Salmonella spp. using traditional bacteriological methods. Salmonella spp. was present in meconium samples of three flocks and in cecal feces of the four flocks. This bacterium was also isolated in the chiller water and in the carcasses of three of the evaluated flocks and in the scalding water of one flock. In this study, S. enterica subspecies enterica 4, 5, 12; S. Corvalis; S. Give; S. Lexington; S. Minnesota; S. Schwarzengrund; S. Rissen and S. Typhimurium were the eight serovars identified.

    Exogenous estrogens, if given in sufficient quantity, stimulate vitellogenesis in the males of vitellogenic species. In the present study, ethanolic solutions of estradiol-17 beta (E2), labeled with 16-alpha-( SVI)iodoestradiol (( SVI)E2) or sodium iodide (Na SVI), were injected into the pectoral muscles of male Japanese quail. The rate of dispersal of the estradiol from the site of injection was measured in vivo during 4 days. The curves of radioactivity appeared to be diphasic. The dose percentages forming the second phase of these curves and the half-time for the second phase were: for 16 mumol E2 (( SVI)E2 label)/100 g body weight, 84.6% and 27.6 hr; for 6 pmol ( SVI)E2/100 g, 20.0% and 17.2 hr; for 16 mumol E2 (Na SVI label)/100 g, 6.7% and 99.0 hr, and for Na SVI, 6.1% and 83.1 hr. Thus, in male quail the estradiol-induced stimulation of vitellogenesis apparently resulted from a continuing hormonal pressure on the liver during the period of study and not from a rapid flow of E2 to the liver shortly after injection.

    Caribbean avifaunal biogeography has been mainly studied based on mitochondrial DNA. Here, we investigated both past and recent island differentiation and micro-evolutionary changes in the Zenaida Dove (Zenaida aurita) based on combined information from one mitochondrial (Cytochrome c Oxydase subunit I, COI) and 13 microsatellite markers and four morphological characters. This Caribbean endemic and abundant species has a large distribution, and two subspecies are supposed to occur: Z. a. zenaida in the Greater Antilles (GA) and Z. a. aurita in the Lesser Antilles (LA). Doves were sampled on two GA islands (Puerto Rico and the British Virgin Islands) and six LA islands (Saint Barthélemy, Guadeloupe, Les Saintes, Martinique, Saint Lucia and Barbados). Eleven COI haplotypes were observed that could be assembled in two distinct lineages, with six specific to GA, four to LA, the remaining one occurring in all islands. However, the level of divergence between those two lineages was too moderate to fully corroborate the existence of two subspecies. Colonisation of the studied islands appeared to be a recent process. However, both phenotypic and microsatellite data suggest that differentiation is already under way between all of them, partly associated with the existence of limited gene flow. No isolation by distance was observed. Differentiation for morphological traits was more pronounced than for neutral markers. These results suggest that despite recent colonisation, genetic drift and/or restricted gene flow are promoting differentiation for neutral markers. Variation in selective pressures between islands may explain the observed phenotypic differentiation.

    This study relates tissue concentrations and toxic effects of Pb in Japanese quail (Coturnix japonica) to the dietary exposure of soil-borne Pb associated with mining and smelting. From 0% to 12% contaminated soil, by weight, was added to 5 experimental diets (0.12 to 382 mg Pb/kg, dry wt) and fed to the quail for 6 weeks. Benchmark doses associated with a 50% reduction in delta-aminolevulinic acid dehydratase activity were 0.62 mg Pb/kg in the blood, dry wt, and 27 mg Pb/kg in the diet. Benchmark doses associated with a 20% increase in the concentration of erythrocyte protoporphyrin were 2.7 mg Pb/kg in the blood and 152 mg Pb/kg in the diet. The quail showed no other signs of toxicity (histopathological lesions, alterations in plasma–testosterone concentration, and body and organ weights). The relation of the blood Pb concentration to the soil Pb concentration was linear, with a slope of 0.013 mg Pb/kg of blood (dry wt) divided by mg Pb/kg of diet. We suggest that this slope is potentially useful in ecological risk assessments on birds in the same way that the intake slope factor is an important parameter in risk assessments of children exposed to Pb. The slope may also be used in a tissue-residue approach as an additional line of evidence in ecological risk assessment, supplementary to an estimate of hazard based on dietary toxicity reference values.

    This study was conducted to investigate and compare the effect of dietary probiotic mixture (PM) and organic acid (OA) mixture with fermented soybean meal (FSBM) on performance, crop, and ceca microbiota, small intestine morphology, and serum lipid profile in Japanese quails. A total of 800 day-old Japanese quails was randomly allotted to 5 treatments with 8 replicate pens of 20 birds each, for 35 days. The experimental diets consisted of a control corn-soybean meal diet and 4 test diets: 1) control diet + 0.1% PM; 2) control diet + 0.2% OA mixture; 3) control diet + the combination of both PM and OA; and 4) an additives-free diet in which the soybean meal in the control diet was replaced with FSBM. The results indicated that in starter and the entire rearing periods, FSBM, PM, and PM+OA diets had significantly lower FCR compared to control or OA diets (P < 0.05). Birds in the FSBM group gained higher weight than control and OA birds (P < 0.05; 1 to 35 d). At d 21 and 35, birds fed the control diet showed significantly lower numbers of lactic acid bacteria in the crop, while coliforms were higher in the cecal content compared to the other diets (P < 0.05). At d 21, the villus height and villus height to crypt depth ratio in the duodenum and jejunum of birds fed PM, PM+OA, and FSBM diets were greater than in other treatments (P < 0.05). The serum concentrations of cholesterol and low-density lipoprotein cholesterol of birds fed PM, PM+OA, and FSBM diets were significantly lower than birds in control and AO groups (P < 0.05). The results obtained herein suggest that FSBM exhibits probiotic properties and, when used in substitution of SBM in Japanese quail diet, can improve growth performance, balance of desirable gastrointestinal microbiota in crop and ceca, small intestinal morphology, and serum lipid profile-likewise, a probiotic supplement.

    An analysis of the mutability of developmental stages of male gametes of the japanese quail (Coturnix coturnix japonica), after irradiation with /sup 60/Co exposures (5.16; 15.48; and 30.96)x10/sup -2/C kg/sup -1/, i.e. 200, 600 and 1200 R, at an exposure rate of 8.59x10/sup -5/C kg/sup -1/s/sup -1/, i.e. O.33 R s/sup -1/, has shown that the rate of overall induced dominant lethality as well as the rate of mutation were highest in spermatocytes of the second order at all exposures. Starting from an exposure of 200 R the following values were found for lethal interference per 1 gamete for 1 R: spermatozoa 2.0x10/sup -3/, spermatides 1.95x10/sup -3/, spermatocytes II 6.1x10/sup -3/, spermatocytes I 4.06x10/sup -3/, spermatogonia in the process of differentiation 6.8x10/sup -3/. When analysing overall embryonic lethality, according to early and late lethality, dominant lethal mutations mainly manifested themsel--ves in the oviductal and germinal developmental periods, so that these periods can be considered as sensitive indices of genetic changes. The spermatogenic epithelium of the japanese quail was found to be greatly radioresistant since not even an exposure to 1200 R caused complete and permanent sterility.

    In order to investigate viral adaptation mechanisms to poultry, we performed serial in vivo passages of a wild bird low pathogenicity avian influenza isolate of the H7N3 subtype (A/mallard/Italy/33/01) in three different domestic species (chicken, turkey, and Japanese quail). The virus under study was administered via natural routes at the dose of 10(6) egg infective dose50/ 0.1 ml to chickens, turkeys, and quails in order to investigate the clinical susceptibility and the shedding levels after infection. Multiple in vivo passages of the virus were performed by serially infecting groups of five naive birds of each species, with samples collected from a previously infected group. Quails and turkeys were susceptible to infection for 10 serial passages, whereas chickens were susceptible to two cycles of infection only. Infection of chicken with the quail- and turkey-adapted viruses showed an increased pathogenicity and/or shedding, causing more severe clinical signs and/or higher levels of viral excretion compared to the original strain. The data obtained herein suggest that infection of selected avian species may facilitate the adaptation of avian influenza viruses originating from the wild bird reservoir to chicken. This is the first time turkey has been shown to act as a species in which a virus from the wild reservoir can increase its replication activity in other domestic species.

    Full Text Available ABSTRACT The effects of increasing levels of soybean acid oil in diets of quails on the quality of eggs were evaluated over a period of 56 days. A completely randomized design with five treatment levels of soybean acid oil (0, 2, 4, 6, and 8% as a replacer for soybean oil and eight replicates of two quails each were used. A total of 240 fresh eggs were used for quality analysis, and 400 eggs were stored at 23ºC over a period of 0, 7, 14, 21, and 28 days for analysis of shelf-life. Polynomial regression and ANOVA with repeated measurements and Tukey´s tests were used. Soybean acid oil linearly increased the intensity of red (a* = -5.26 + 0.14 x, R2 = 0.89, P = 0.01 and yellow (b* = 42.32 + 0.44 x, R2 = 0.88 P = 0.01. All other variables of egg quality were not affected by the treatments, with the exception of sensory attributes, such as odor and aftertaste, which were more pronounced with soybean acid oil. In conclusion, soybean acid oil affects the intensity of yellow and red color of the yolk. Trained assessors detected differences in odor and aftertaste of eggs when soybean acid oil was included in the quail diet.

    Adult Japanese quail were administered 100 mg/kg chlorophenyl-labeled [ 14 C]fenvalerate, α-cyano-3-phenoxybenzyl 2-(4-chlorophenyl)isovalerate, for study of its distribution, elimination, and metabolism. Ninety percent of the administered dose was eliminated in the excreta within the first 24 h. In addition to fenvalerate, the following metabolites were present: benzeneacetic acid, 4-chloro-α-(1-methylethyl)-,cyano(3-phenoxy-4-hydroxyphenyl)methyl ester [4'-OH-fenvalerate]; benzeneacetic acid, 4-chloro-α-(1-methylethyl)-,(aminocarbonyl)(3-phenoxyphenyl)methyl ester [CONH 2 -fenvalerate]; 4-chloro-α-(1-methylethyl)benzeneacetic acid[Cl-V acid]; 4-chloro-α-(2-hydroxy-1-methylethyl)benzeneacetic acid[4-OH-Cl-V acid]. In time course studies radiocarbon peaked at 3 h (9μg/g) in the liver and gradually declined, while in the blood it peaked within 2 h and fell quickly to an equilibrium value of 1.5 μg/mL blood. In liver microsomal and isolated heptatocyte preparations of Japanese quail and rat, the following metabolites were identified: Cl-V acid, 4-OH-Cl-V acid, 4'-OH-fenvalerate, CONH 2 -fenvalerate. Oxidation was found to be the predominant route of degradation either pre- or post-hydrolysis of the parent compound. Rapid excretion, lesser absorption, and faster metabolism probably explain the lower toxicity of fenvalerate to birds compared to rats

    The incorporation of 65 Zn into eggs was investigated after single or daily intraperitoneal administration to laying Japanese quails. After a single intraperitoneal administration, 65 Zn appeared first in the 2nd egg yolks and reached the highest level in the 3rd and 4th ones, followed by a gradual decrease. The cumulative amount of 65 Zn in the egg yolks over a period of 3 weeks accounted for about 40% of dose. After daily intraperitoneal administration, the 6th-9th egg's yolks contained the highest radioactivity of the eggs examined. Whole-body retention patterns were also observed in both of the experiments. (auth.)

    The immunocompetence handicap hypothesis (ICHH) suggests that the male sex hormone testosterone has a dual effect; it controls the development and expression of male sexually selected signals, and it suppresses the immune system. Therefore only high quality males are able to fully express secondary sexual traits because only they can tolerate the immunosuppressive qualities of testosterone. A modified version of the ICHH suggests that testosterone causes immunosuppression indirectly by increasing the stress hormone corticosterone (CORT). Lines of Japanese quail (Coturnix japonica) selected for divergent responses in levels of plasma CORT were used to test these hypotheses. Within each CORT response line (as well as in a control stock) we manipulated levels of testosterone in castrated quail by treatment with zero (sham), low or high testosterone implants, before testing the birds' humoral immunity and phytohaemagglutinin (PHA)-induced immune response, as well as body condition. The PHA-induced response was not significantly affected by CORT selected line, testosterone treatment or their interaction. There was, however, a significant effect of CORT line on humoral immunity in that the control birds exhibited the greatest antibody production, but there was no significant effect of testosterone manipulation on humoral immunity. The males in the sham implant treatment group had significantly greater mass than the males in the high testosterone group, suggesting a negative effect of high testosterone on general body condition. We discuss these results in the context of current hypotheses in the field of sexual selection.

    Neo hatched Japanese quails chicks were divided equally into three groups (G1, G2 and G3) and injected once subcutaneously with monosodium glutamate (MSG) at 0,2 or 4 mg/g body weight for G1, G2 and G3 respectively. The obtained results clear that, 1-At-marketing stage, body weight increased by about 4% and 6%, feed conversion ratio reduced by 8.7% and 5.7% in-groups G2 and G3 respectively. 2-MSG had no significant effect on male and female serum T4 as well as male serum T3. The injection with 2-mg MSG per gram body weight increased female serum T3 significantly. 3-MSG increased significantly fat % DM in the male and female quails. This treatment in was positively correlated with the amount of injected MSG. Ash % DM and protein % DM were decreased significantly in both injected males and females and the reduction was dose dependent. 5-in males, weights of heart, spleen and testes besides weights and lengths of gastrointestinal tract regions were not significantly affected by MSG administration. 6-in females, the injection with MSG (2 mg/g body weight) significantly reduced the weight as percent body weight, moreover, the administration of MSG had no significant effect on the weights or the lengths of the remain parameters of the females gastrointestinal tract regions, ovary, oviduct, heart and spleen

    Full Text Available ABSTRACT This study was designed to find the effect of vitamin E supplementation on growth, serum antioxidant enzymes, and some trace elements in Japanese quail (Coturnix coturnix japonica under low ambient temperature. A total of 180 day-old Japanese quails were randomly divided into four groups and provided with 0 (group A, 50 (group B, 100 (group C, and 150 IU/kg (group D vitamin E (dl-α-tocopherol acetate under an average temperature of 9±0.5 °C for an experimental period of 42 days. The result showed that feed intake per day, body weight, weight gain per day, and feed conversion ratio did not differ significantly between the groups. Serum concentrations of superoxide and glutathione peroxidase were significantly high in birds supplemented with 150 mg/kg of vitamin E. The concentration of aspartate aminotransferase was not significantly affected between the control and treated groups; however, alanine transaminase concentration significantly reduced in group D. Zinc concentration in the blood increased significantly in group D, with no significant effect on copper and manganese between the control and treated groups. Vitamin E at the level of 150 IU/kg of feed improves the blood antioxidant status and zinc concentration, with no effect on the performance traits of quail reared under low ambient temperature.

    This experiment was conducted to evaluate the effects of different levels of nanosilicon dioxide (nSiO2) on performance, egg quality, liver histopathology and concentration of calcium (Ca), phosphorus and silicon (Si) in egg, liver and bone in laying quails. The experiment was administered using 60 laying quails at 16-26 weeks of age with five treatments [0 (control), 500, 1000, 2000 and 4000 mg nSiO2 per kg of diet] and four replicates in a completely randomized design. During the experiment, the amount of feed intake was recorded weekly and performance parameters were measured. During the last 3 days of the experiment, all of the eggs in each replicate were collected and egg quality parameters were measured. At the end of 26 weeks of age, the birds were sacrificed and blood samples were collected. Liver samples from each treatment were fixed in 10% buffered formalin for histopathological assessment. The right thigh bone and a portion of liver were inserted in plastic bags and stored at - 20. The results showed that nSiO2 supplementation significantly affected egg weight and egg mass ( P 0.05) by dietary treatments. In conclusion, the results indicated that dietary supplementation of nSiO2 could improve bone density and performance without any adverse effect on the health of laying quails.

    Free (surface) avian respiratory macrophages (FARMs) were harvested by lavage of the lung/air-sac system of the rock dove, Columba livia. The presence of FARMs in the atria and infundibula was confirmed by scanning electron microscopy. The respiratory system has developed several cellular defence lines that include surface macrophages, epithelial, subepithelial and interstitial phagocytes, and pulmonary intravascular macrophages (PIMs). Hence, C. livia appears to have a multiple pulmonary cellular protective armoury. Ultrastructurally, the FARMs and the PIMs were similar to the corresponding cells of mammals. The purported high susceptibility of birds to respiratory diseases, a state that has largely been deduced from morbidities and mortalities of commercial birds, and which has chiefly been attributed to paucity of the FARMs, is not supported by the present observations.

  6. A Dragon and a Dove? A Comparative Overview of Chinese and European Trade Relations with Sub-Saharan Africa

    Full Text Available As China’s footprint in African trade grows larger by the day, the need to contextualize this rise through comparative analysis becomes ever more necessary. This paper contrasts the sub-Saharan trade relations of both China and Europe with their respective designated stereotypes: those of a dragon and a dove. The article compares the trade dynamics on four levels: the policies and institutional mechanisms that shape the relationship; the composition of the trade flows; the geographic distribution of trade dominance; and the influence of norms and values on the trade pattern. It concludes that although there are empirical grounds behind these stereotypes, Chinese and European trade relations with sub-Saharan Africa are becoming more similar, partly due to a more hawkish European stance.

    Full Text Available Aim: The objective of this study was to evaluate the effect of feeding fermented fish silage (FFS on serum biochemical parameters of Japanese quails (Coturnix coturnix japonica. Materials and Methods: A total of 192, 7-day-old broiler Japanese quail chicks of either sex, were randomly distributed into four dietary treatments with four replicates in each group having 12 chicks in each replicate pen. The dietary treatments were T1 - Control diet, T2 - Diet containing 5% FFS, T3 - Diet containing 10% FFS, and T4 - Diet containing 15% FFS. Group body weight and feed consumption were recorded at weekly intervals. Feed conversion ratio (FCR was derived by dividing the feed consumed with the weekly body weight gain. At the end of the experiment, 8 birds from each treatment were selected randomly and sacrificed by cervical dislocation to study the carcass traits expressed as % pre-slaughter live weight. At 5 weeks of age, about 2 ml of blood was taken from the jugular vein of each selected bird, and serum samples were separated after centrifugation. Total protein, albumin/globulin (A/G ratio, calcium, phosphorus, triglyceride, total cholesterol, high density lipoprotein-cholesterol (HDL-C, very low density lipoprotein-cholesterol (VLDL-C, low density lipoprotein-cholesterol (LDL-C, alanine aminotransferase (ALT, and aspartate aminotransferase (AST were estimated in the serum. Results: The cumulative body weight gains from 1 to 5 weeks of age did not vary significantly between control and 5% FFS group. However, a linear decrease in body weight gain was observed by increasing the levels of FFS beyond 5% in the diet. The cumulative feed consumption was significantly higher in case of birds under control group during 1-5 weeks of age as compared to birds fed FFS based diet (5%, 10%, and 15%. No statistical difference in cumulative feed conversion ratio could be noticed during 1-5 weeks of age. The eviscerated yield decreased and giblet weight increased due

    Previous coefficients for transfer of technetium from feed to poultry have utilized default values. These investigations examined the uptake and distribution of /sup 95m/Tc in male and female Japanese quail following their ingestion of Tc incorporated into alfalfa during growth. Approximately 8% of the daily ingested Tc was transferred to eggs. Biological half-time was one to two days. After 10 days of feeding, 80% of the Tc was in yolk, 20% in albumin, and less than 1% in shell and associated membranes. The Tc levels in albumin reached a maximum between three and five days, compared to six to seven days for yolk. Laying female quail contained 27% of the daily-ingested Tc compared to 5% for males. However, approximately 23% of the daily female Tc intake was contained in the developing ova and reproductive organs. The highest Tc concentrations were in oocytes of laying hens, followed by the fully formed unlaid egg and the ovaries. The uterine shelled egg contained five times the amount of Tc present in other edible tissues combined. For males, the gizzard contained about 53% of the Tc in other edible tissues, followed by muscle (25%), liver (19%), and heart (3%). The transfer coefficient (pCi/kg edible tissue per pCi/day) for plant-incorporated /sup 95m/Tc was about 0.35 day/kg for both sexes. 17 references, 4 tables

    Full Text Available Enterococci isolated from the crop and caecum of Japanese quails exposed to 7 day conditions of microgravity were re-vitalized after their dry-freezing long storage. Originally, the strains were isolated from Japanese quails after their landing from flight onboard the orbital station Mir during the experiment in August 1990. Because taxonomy as well as the studies concerning the bacteriocins, especially those produced by enterococci, have been continually developed for years, the aim of this study was to confirm species identification, stability of the properties of enterococci as well as to test new properties after their long storage. Genotyping allotted the strains to the species E. faecium. Lactic acid production was detected in similar amounts in the strains before and after their long-storage in dry-frozen form. The strains were vancomycinsensitive and kanamycin-resistant before as well as after their long-time storage. Variability in sensitivity to different antibiotics was found among the strains tested even before and after longtime storage. Each of the strains possessed at least one structural enterocin gene. The structural genes for enterocin A, P, B, L50B were detected in E. faecium EP7. E. faecium EP2, EEP4 have the genes for ent A, B, L50B. The gene for ent P was detected only in the strain EP7. The most often detected was ent A gene followed by ent genes B, L50B. All strains inhibited growth of at least 4 out of 15 indicators. The stability of the enterococcal properties determined before as well as after their dry-freezing was not influenced during their long-term storage; moreover, new properties were determined.

    Invasive species are regularly claimed as the second threat to biodiversity. To apply a relevant response to the potential consequences associated with invasions (e.g., emphasize management efforts to prevent new colonization or to eradicate the species in places where it has already settled), it is essential to understand invasion mechanisms and dynamics. Quantifying and understanding what influences rates of spatial spread is a key research area for invasion theory. In this paper, we develop a model to account for occupancy dynamics of an invasive species. Our model extends existing models to accommodate several elements of invasive processes; we chose the framework of hierarchical modeling to assess site occupancy status during an invasion. First, we explicitly accounted for spatial structure and how distance among sites and position relative to one another affect the invasion spread. In particular, we accounted for the possibility of directional propagation and provided a way of estimating the direction of this possible spread. Second, we considered the influence of local density on site occupancy. Third, we decided to split the colonization process into two subprocesses, initial colonization and recolonization, which may be ground-breaking because these subprocesses may exhibit different relationships with environmental variations (such as density variation) or colonization history (e.g., initial colonization might facilitate further colonization events). Finally, our model incorporates imperfection in detection, which might be a source of substantial bias in estimating population parameters. We focused on the case of the Eurasian Collared-Dove (Streptopelia decaocto) and its invasion of the United States since its introduction in the early 1980s, using data from the North American BBS (Breeding Bird Survey). The Eurasian Collared-Dove is one of the most successful invasive species, at least among terrestrial vertebrates. Our model provided estimation of the

    The effect of dopaminergic drugs on the timing of conditioned keypecking in ring doves was studied in two experiments. Subjects were given pairings of a keylight with food and the temporal distribution of keypecks was obtained during unreinforced probe trials. Experiment 1 demonstrated that injections of pimozide before each session immediately decreased response rates but shifted timing distributions gradually to the right over several days of treatment. Experiment 2 showed similar results using a longer interstimulus interval (ISI). No shifts were observed when the drug was injected after training sessions, or when a delay, identical to each subject's average latency to eat during the drug condition, was inserted between keylight offset and food presentation. Consequently, the shifts in timing were mediated neither by mere accumulation of the drug nor a delay from keylight offset to food presentation resulting from the drug's ability to slow motor processes. The results suggest that pimozide modulates response rate through its effect on motor processes or incentive value, and response timing through a conditioned response (CR) to injection-related cues established via their repeated pairings with the drug.

    A total number of 1600 fertile eggs from japanese quail birds were used in this study. The eggs were divided into eight groups then incubated. NDV and vite were administered to the groups of eggs in Ovo injection at day 14 from incubation. Hatchability, body weight, egg production and mortality were recorded weekly for each group. Five blood samples were collected weekly from each group to measure total serum proteins, albumin, globulin, T3, T4 and HI titre. The results of this work revealed an increase in total serum proteins, globulin, and a decrease in t3, T4 and albumin values of the in ove vaccinating groups. Also HI titre recorded higher values due to ovo vaccination alone or combined with vit. E. It was noticed that the group injected by inactive vaccine plus vit. E registered high increases in hatchability, body weight and egg production beside a decrease in mortality

    Freud began his career as a neurologist studying the anatomy and physiology of the nervous system, but it was his later work in psychology that would secure his place in history. This paper draws attention to consistencies between physiological processes identified by modern clinical research and psychological processes described by Freud, with a special emphasis on his famous paper on depression entitled 'Mourning and melancholia'. Inspired by neuroimaging findings in depression and deep brain stimulation for treatment resistant depression, some preliminary physiological correlates are proposed for a number of key psychoanalytic processes. Specifically, activation of the subgenual cingulate is discussed in relation to repression and the default mode network is discussed in relation to the ego. If these correlates are found to be reliable, this may have implications for the manner in which psychoanalysis is viewed by the wider psychological and psychiatric communities.

    Full Text Available The Japanese quail is one of the smallest bird subspecies which has been tamed by man, being industrially raised in our days in many states over the world. This avian subspecies produces over 300 eggs, and though there are about 6 races and different varieties, there are very little data in the scientific literature regarding the quality values for eggs of Japanese quail hatching eggs collected from hens at the end of the laying – physical values (pH value of the eggs components, albumen index, yolk index The present paper wants to bring a series of data regarding some of these indicators. The pH values was determined with an portable pH-oximeter, and to establish the other two quality indexes we used a device fitted with callipers taking into account: height of the dense egg white (albumen, minimum and maximum diameter of the dense and fluid egg white, height and the diameter of the yolk. The albumen pH recorded values of 8.90, and the yolk pH values of 6.07. The statistical mean for the 130 values of albumen index taken in study was 0.048. The mean value of yolk index was 0.399. The obtained results are normal for the period of quail’s life.

    Full Text Available The metabolizable energy (ME determination for foods used in quail diets, through metabolism assays, takes time, infrastructure and financial resources, which makes the development of prediction equations based on proximal composition of foods to estimate the ME values of particular interest. The objective of this study was to adjust the prediction equations of metabolizable energy (ME of corn for quail. The chemical compositions of 12 maize varieties were determined and a metabolism assay was carried out in order to determine the apparent metabolizable energy (AME and nitrogen-corrected apparent metabolizable energy (AMEn of these corn varieties. The values of chemical composition, AME and AMEn, converted to dry matter, were used to adjust the prediction equations. The initial adjustment of simple and multiple linear regression of the AME and AMEn was performed using the values of crude protein (CP, ether extract (EE, neutral (NDF and acid (ADF detergent fiber, mineral matter (MM, calcium (Ca and phosphorus (P as regressors (full model. To adjust the prediction equations the statistical procedure of simple and multiple linear regression was used, with the technique of indirect elimination (Backward. There was adjustment of 10 prediction equations, in which five were for AME and another five for AMEn, the R² values of which ranged from 0.20 to 0.75 and from 0.21 to 0.78, respectively. For all adjusted equations, negative correlations for MM were observed, which may be related to its dilutive effect of the gross energy contained in corn. In conclusion, the equations that showed better adjustment were AME= 5605.46 - 385.074CP + 111.648EE + 48.1133NDF + 303.924ADF - 929.931MM (R²= 0.75 and AMEn= 5878.16 - 403.937CP + 81.9618EE + 41.8954NDF + 303.506FDA - 901.621MM (R²= 0.78.

    Full Text Available Objetivou-se avaliar o desempenho de codornas japonesas na fase de postura alimentadas com dietas contendo soja integral processada. Utilizaram-se 320 codornas japonesas fêmeas com 29 semanas de idade e peso inicial de 186,1 ± 4,0 g, distribuídas em delineamento inteiramente casualizado, com oito repetições, cada uma com dez aves por unidade experimental. As dietas foram isocalóricas e isonutritivas para proteína bruta, lisina digestível, metionina + cistina digestível, cálcio, fósforo disponível e sódio. Assim, foram avaliadas uma dieta controle, à base de milho e farelo de soja, e outras três, com substituição parcial do farelo de soja por soja integral tostada, extrusada ou micronizada, de modo que a soja integral forneceu 50% da proteína bruta proporcionada pelo farelo de soja na dieta controle. Não foram observadas diferenças na produção e na massa de ovos, na conversão alimentar, na viabilidade das aves, na porcentagem de ovos comercializáveis, no peso específico dos ovos, na porcentagem de gema e de albúmen nem na porcentagem de casca dos ovos. A substituição de farelo de soja por soja integral tostada ocasionou redução no consumo de ração. Não foram observadas diferenças nos parâmetros estudados quando o farelo de soja foi substituído por soja integral extrusada. A substituição de farelo de soja por soja integral micronizada reduziu a variação de peso corporal das codornas, resultando em perda de peso das aves. O farelo de soja pode ser substituído, em 50% da proteína, por soja integral tostada ou extrusada em dietas para codornas japonesas em postura. Entretanto, a substituição do farelo de soja por soja integral micronizada, em 50% da proteína, é desaconselhável, pois piora o desempenho, ocasionando principalmente perda de peso das aves.This work aimed at evaluating the performance of Japanese quails fed diets with processed whole soybean during the laying phase.

    Alterations in the basal transcription rates of eukaryotic genes are believed to involve the binding of trans-acting factor(s) with specific DNA sequences in the promoter. We show here two interrelated events for the VTGII gene of the old, non-egg laying Japanese quail: alterations in the structure of the chromatin encompassing the gene, and binding of trans-acting factors to the promoter of the gene. Estradiol/progesterone alone or together cause alterations in the conformation of the chromatin of the promoter region of the gene. This may allow free access of nuclear protein(s) to the cis-acting elements, ERE, PRE and NF1, in the promoter of the gene and cause activation of transcription.

    Full Text Available Abstract Freud began his career as a neurologist studying the anatomy and physiology of the nervous system, but it was his later work in psychology that would secure his place in history. This paper draws attention to consistencies between physiological processes identified by modern clinical research and psychological processes described by Freud, with a special emphasis on his famous paper on depression entitled 'Mourning and melancholia'. Inspired by neuroimaging findings in depression and deep brain stimulation for treatment resistant depression, some preliminary physiological correlates are proposed for a number of key psychoanalytic processes. Specifically, activation of the subgenual cingulate is discussed in relation to repression and the default mode network is discussed in relation to the ego. If these correlates are found to be reliable, this may have implications for the manner in which psychoanalysis is viewed by the wider psychological and psychiatric communities.

Foram utilizadas 180 codornas japonesas (Coturnix japonica, com 98 dias de idade, distribuídas em delineamento inteiramente casualizado em esquema de parcelas subdivididas, composto por cinco tratamentos e seis repetições com seis aves cada. O experimento foi dividido em seis períodos de quatro dias, totalizando 24 dias. Foram analisados o desempenho produtivo e a qualidade dos ovos das codornas. A cor da gema foi avaliada a cada quatro dias durante 24 dias pelo método do escore colorimétrico DSM. Não houve efeito dos tratamentos sobre o desempenho e a qualidade dos ovos das codornas, à exceção da cor da gema. O extrato de marigold proporcionou escore colorimétrico da gema equivalente ao das aves alimentadas com milho. A suplementação associada dos extratos de marigold e páprica proporcionou maior escore colorimétrico e em menor tempo. A utilização de pigmentantes naturais deve ser analisada considerando o escore colorimétrico que se deseja obter e o custo da suplementação de cada fonte comercial.The objective was to evaluate the effects of natural pigments from marigold extract and paprika to Japanese quails fed sorghum-based diets.

    Introduction As part of a U.S. Geological Survey (USGS) monitoring plan to evaluate the environmental impact of off-highway vehicle (OHV) use on Bureau of Land Management (BLM) land in California, this report presents results of geologic studies in the Dove Spring OHV Open Area. This study produced baseline data, which when combined with historic and current patterns of land use, forms the basis for vegetation and wildlife monitoring designed to address the following questions: 1. Is the density and length of OHV routes increasing? 2. Are there cumulative effects of past and current OHV use associated with changes in the environmental integrity of soils, plants, and wildlife? 3. Is the spread of invasive species associated with levels of OHV use? 4. Is there a threshold of OHV impact that might be translated to management action by the BLM? The monitoring studies will be used to collect baseline environmental information to determine levels of environmental impact of OHV use. This approach will use a low-impact area as a proxy for pre-impact conditions (substituting space for time) to determine thresholds of OHV impacts beyond which environmental integrity is affected. Indicators of environmental integrity will emphasize factors that are fundamental to ecosystem structure and function and likely to be sensitive to OHV impacts. Surficial geology is studied because material properties such as texture and chemistry strongly control soil moisture and nutrient availability and therefore affect plant growth and distribution. An understanding of surficial geology can be used to predict and extrapolate soil properties and improve understanding of vegetation assemblages and their distribution. In the present study, vegetation associations may be examined as a function of surficial geology as well as other environmental variables such as slope, aspect, NRCS (National Resources Conservation Service) soil classification, elevation, and land-use history.

    Full Text Available The quail for being an alternative species will be able to supply a new market niche due to its fast growth, high laying rate, low feed intake, in addition to the increase of the acceptance of its products by the consumer. A growing interest in raising the stocking rates in the cages as an alternative to increase the performance of the stock is noticed; although studies demonstrate that high densities can result into unfavorable environment to the birds’ welfare with alterations in the performance of the flocks and as a stressing factor being able to alter the production and profitability of the flock. At high stocking rates, the birds become predisposed to aggressiveness reactions, presenting cannibalism behavior, besides the combination of factors such as pH, temperature, ventilation and humidity deficiency which create environmental conditions favorable for certain benign bacteria which utilize uric acid of the manure through their enzymatic complexes and produce ammonia, causing stress to birds and which can cause damages to performance with significant economic losses to the producer.  The experiment with 112-day duration was conducted with the objective of evaluating the inclusion of acidulants in the Japanese quails’ drinking water and verifying the effect on the stocking rate in cages. A completely randomized design with four treatments (2 stocking rates of quails x 2 additions of and 5 replications of 24 and 36 birds per cage, corresponding to the stocking rates of 141.67 and 94.44 cm2/bird, respectively, receiving or not acidulant in the water (acetic, lactic and phosphoric acid was utilized.

    Male Japanese quail were exposed to 14-hr (5:00-19:00) light:10-hr darkness (14 L:10D) from 1 day to 28 days of age and exposed to 8 L (5:00-13:00); 16D from 29 days to 49 days of age. Thereafter the birds were again transferred to 14L:10D for photostimulation. Gonadotropic activities of the anterior lobes of the pituitary were measured at various times during the 24-hr period in relation to testicular growth with a blossary method based on sup(32P)-uptake by one-day-old chick tests. The mean testicular weights increased from the 2nd to 35th day of exposure to 14L:10D and an abrupt increase was observed between the 7th and 21st day. Thereafter the weight reached a plateau. Under 8L:16D and on the 1st day of exposure to 14L:10D, no diurnal changes in the pituitary gonadotropic activity were observed but on the 2nd day the activity showed a peak at 19:00 (14 hr after the onset of light). On the 7th and 21st day, two peaks of the activity were found at 8:00 (3 hr after the onset of light) and 22:00 (17 hr after the onset of light or 3 hr after the onset of darkness). However, only one peak was found at 19:00 (14 hr after the onset of light) on the 35th and 49th day. These results indicate that the diurnal rhythm of pituitary gonadotropic activity of male quail appears after transfer of the birds from short days to long days, and that the diurnal pattern changes with photoperiodically induced testicular growth.

    The origins of psychoanalysis, as well as the concerns of our daily endeavors, center on engagement with the fate of the unbearable - be it wish, affect, or experience. In this paper, I explore psychological states and dynamics faced by survivors of genocide and their children in their struggle to sustain life in the midst of unremitting deadliness. Toward this continuous effort, I re-examine Freud's theoretical formulations concerning memory and mourning, elaborate André Green's concept of the 'Dead Mother', and introduce more recent work on the concepts of the 'third' and 'thirdness'. Throughout, my thoughts are informed by our clinical experience with the essential role of witnessing in sustaining life after massive trauma. I bring aspects of all these forms of knowing to reflections about a poem by Primo Levi entitled Unfinished business and to our own never finished business of avoiding denial while living in an age of genocide and under the aura of uncontained destructiveness.

    The aim of the present study was to investigate the efficacy of early probiotics (single dose) administered in different ways, on quails' performance, small intestine morphology, blood biochemistry, and immune response. In total, 192 day-old chicks were used in one of the following experimental groups before being transferred to a raising room: 1) Control (no probiotic administered), 2) oral gavage, 3) spray, and 4) vent lip. Four replicates of 12 chicks per cage were considered for each treatment and birds were raised up to 35 d in the same conditions. Probiotic treated birds had higher d 1 to 35 feed intake than the control group (P birds had a higher body weight gain as compared to the control (P birds compared to control (P  0.01). None of the immune-related parameters were affected by the probiotic (P > 0.05). Single dose usage of probiotics exerts its beneficial effects on quails' body weight gain, feed intake and mortality in 1 to 35 d period, regardless of the route of administration. This work generally supports the efficacy of single-dose usage of probiotics and suggests the spray of probiotics as an early, single-dose administration method. © 2017 Poultry Science Association Inc.

    Full Text Available This experiment was conducted to assess the effects of Silymarin on oxidative status, bone characteristics, and some blood parameters in Japanese quail subjected to oxidative stress induced by carbon tetrachloride (CCl4. The experiment was performed as a completely randomized design with four replicates, each with 30 birds, using a 2 × 2 factorial arrangement with two doses of Silymarin (0 and 1 mL/kg BW and CCl4 (0 and 1 mL/kg BW. Results revealed that the interaction between Silymarin and CCl4on concentrations of total cholesterol, triglycerides, glucose, albumin, calcium, and alkaline phosphatase were significant (P < 0.05. In contrast, concentrations of phosphorus, total protein, and high density lipoprotein-cholesterol in blood serum did not differ between experimental treatments. Experimental treatments had a significant effect on superoxide dismutase activity in blood serum (P < 0.05, but not on glutathione peroxide activity and malondialdehyde concentration. Experimental treatments significantly affected the weight, thickness, and external and internal diameters of tibia bone (P < 0.05, but not its length, ash, volume, and density. This study shows that Silymarin has potential to attenuate adverse effects of oxidative stress induced by CCl4 in Japanese quail.

    Full Text Available Background: Early nutrition of chicks with beneficial bacteria might help in occupying the inner surface of the intestinal tract. Interference of pathogens in intestinal microbiota is well known as barrier effect, bacterial interference, and competitive exclusion. Objectives: It was hypothesized that competitive exclusion in Japanese quails with a blend of beneficial bacteria (Aquablend Avian® probiotic would enhance quails’ growth performance and intestinal mucosal morphology. Furthermore, the study was performed at 2100 m above sea level at Shahrekord University, so another hypothesis was the capability of the probiotic for inhibiting right heart failure. Materials and Methods: One hundred fifty-six Japanese quails were divided into 4 groups: 2 groups (Aquablend and control at standard environmental temperature and 2 (Aqua-stress and Cont-stress at cold-hypoxic environmental situation. Aquablend groups received the probiotic in the first 3 days of life in drinking water (0.5 g/100 birds/day. Results: Feed conversion ratio (FCR was significantly reduced at the end of the experiment (day 35 in both Aquablend and aqua-stress groups compared to control and cont-stress groups, respectively (P 0.05. Cont-stress group had higher RV: TV ratio (0.28 and heterophil: lymphocyte (H: L ratio (1.22 than aqua-stress group: (0.25 and (1.20, respectively (P > 0.05. Data regarding to intestinal mucosa morphology was controversial but the probiotic was able to elevate duodenum villi surface (P < 0.05 and also jejunum and ileum lamina propria thickness. Conclusion: Obtained data suggests that addition of Aquablend Avian® probiotic in the first 3 days of life may improve growth performance and some intestinal mucosa characteristics of Japanese quails. Moreover, the probiotic might reduce right heart failure and stress induced by cold-hypoxic situation.

    Interpersonal attachment and drug addiction share many attributes across their behavioral and neurobiological domains. Understanding the overlapping brain circuitry of attachment formation and addiction illuminates a deeper understanding of the pathogenesis of trauma-related mental illnesses and comorbid substance use disorders, and the extent to which ending an addiction is complicated by being a sort of mourning process. Attention to the process of addiction recovery-as a form of grieving-in which Kubler-Ross's stages of grief and Prochaska's stages of change are ultimately describing complementary viewpoints on a general process of neural network and attachment remodeling, could lead to more effective and integrative psychotherapy and medication strategies.

    Thirty-week-old female bobwhite quail (Colinus virginianus), maintained at 26 + 1?C, were provided diets containing 0,25, or 100 ppm parathion ad libitum. After 10 days, birds were exposed to mild cold (6 + 1?C) for 4,8, 12, 24, or 48 hr. Brain acetylcholinesterase activity was inhibited in a dose-dependent manner in birds receiving 25 and 100 ppm parathion. Body weight, egg production, and plasma luteinizing hormone and progesterone concentrations were reduced in birds receiving 100 ppm parathion compared with other groups. Cold exposure did not alter plasma corticosterone levels in the 0- and 25-ppm parathion groups, but a two- to five fold elevation of plasma corticosterone was observed in birds fed 100 ppm parathion. These findings indicate that (i) short-term ingestion of parathion can impair reproduction possibly by altering gonadotropin or steroid secretion, and (ii) tolerance to cold may be reduced following ingestion of this organophosphate.

    The experiment was designed to study the effects of replacing cotton seed oil (CSO) with Used Restaurant Oil (URO) in Japanese quail diets on performance, fatty acid composition of the carcass and egg and concentration of iodine metabolites. URO was added to the diets at 0, 1, 2 or 4 % at the expense of CSO (4 %) in the control diet during a 10-week trial period. Feed intake, weight gain, feed conversion, mortality rate, triiodothyronine (T3), and thyroxine (T4) were not significantly (p>0.05) affected by the levels of used restaurant ,oi). Replacing 25,% or 50 % of CSO with URO had no significant (p>0.05) effect on linoleic acid content of carcass and egg. In contrary, linoleic acid content was reduced significantly (p<0.05) in the carcass and egg of the group which fed on the diet with 4 % URO. It can be concluded that used restaurant oil can be supplemented to the Japanese quail diets at the levels of 1 % and 2 % without any determine effect on the performance and the fatty acid profile of carcass and egg. rat supplementation to broiler chicken is a long standing practice for improving the consistency and palatability of the diets; increasing the energy density of broiler meat; stimulating growth and utilization of food and energy; feed efficiency; egg size, yield, and hatch ability (Carew and Hill, 1964; Vermeersch and Vanschoubroek, 1968 and Summers and Lesson, 1979 ). Poultry required fat in the diet as a source of essential fatty acids and to facilitate supply and absorption of vitamins (Clarke et al, 1977). Oil may be added to poultry diets in order to meet the 1% linoleic acid requirements

    Full Text Available Objective The current study aimed to investigate the impact of high-fat diets composed of different animal and vegetable fat sources on serum metabolic health markers in Japanese quail, as well as the overall lipid content and fatty acid profiles of the edible bird tissues following significantly increased dietary lipid supplementation. Methods Fifty seven male quail were divided into six groups and fed either a standard diet or a diet enriched with one of five different fats (22% coconut oil, lard, palm oil, soybean oil, or sunflower oil for 12 weeks. The birds were subjected to an oral glucose tolerance test following the feeding period, after which they were euthanized and blood, liver, breast, and thigh muscle samples collected. Total fat content and fatty acid profiles of the tissue samples, as well as serum uric acid, triglyceride, cholesterol, total protein, albumin, aspartate transaminase, and total bilirubin concentrations were assessed. Results High-fat diet feeding had no significant effects on the glucose tolerance of the birds. Dietary fatty acid profiles of the added fats were reflected in the lipid profiles of both the liver and breast and thigh muscle tissues, indicating successful transfer of dietary fatty acids to the edible bird tissues. The significantly increased level of lipid inclusion in the diets of the quail used in the present study was unsuccessful in increasing the overall lipid content of the edible bird tissues. Serum metabolic health markers in birds on the high-fat diets were not significantly different from those observed in birds on the standard diet. Conclusion Thus, despite the various high-fat diets modifying the fatty acid profile of the birds’ tissues, unlike in most mammals, the birds maintained a normal health status following consumption of the various high-fat diets.

    2016-06-01

    The authors discuss the relation between perverse psychic formations and the ability to develop a mind of one's own. The authors characterize the formation of perversity in terms of failure to develop the key capacities of thinking, mourning, and loving. These failures result in the abolishment of thinking and the repudiation of separateness and lead to the creation of different kinds of twisted coalitions, which shape the transference-counter-transference matrix. Persons with perverse psychic organizations have difficulties developing their own minds due to their refusal to acknowledge human limitations and their inability to accept the fundamental differences of human existence: self-other, child-adult, male-female. These characterizations are illustrated by clinical material, including a detailed analytic session, demonstrating the perverse aggresivization and sexualization of the analytic relationship. The role of the analyst is to detoxify the violence and destruction and to translate the language of perversion into the language of love.

The experimental design used was completely randomized with five treatments (five different particle sizes of limestone and five replicates of 16 birds each in a total of 400 birds. The treatments were: T1 – Diets with 100% of the limestone coarse; T2 – diets with 70% of limestone coarse and 30% fine; T3 – diets with 30% of limestone coarse and 70% fine; T4 - Diets with 100% of the limestone fine and T5 – Diets with 100% of medium limestone. The experimental diets were formulated to meet NRC (1994 nutritional requirements. The treatment of 100% fine particle size improved egg production and bird performance compared to the treatment with 100% medium particle size. There was no effect of limestone particle size on shell quality of quail eggs. The fine or coarse limestone particle size can be used in diets of laying quails. The medium limestone particle size is not recommended on laying Japanese quail diets. KEY WORDS: Limestone, particle size, japonese quails, egg production, shell egg quality.

    This paper explores a subjective experience-and identification-that a cohort of Indian women identifies as "home." This experience of "home" provides an attachment to a collective melancholia that keeps in place a prohibited female sexual subjectivity. The paper provides a brief historical overview of the prohibition of female sexual subjectivity and erotic agency in India. Following this, it discusses women's masturbation fantasies that illustrate the toggle between women's permitted and prohibited identifications. A clinical case example is presented to illustrate the hopelessness and mourning inherent in the psychoanalytic journey into subjectivity, a journey involving a departure from a shared cultural history.

The test groups were fed a diet containing aerial parts (leaves, stems, and flowers) of Senecio vernalis (SV group), Heliotropium dolosum (HD group), or Heliotropium circinatum (HC group) at the level of 30% for 6 weeks, and the control group was fed 0% in order to evaluate parental and progenial toxicity, along with the transference of alkaloid residues to their eggs. The pyrrol...

    Full Text Available O objetivo do presente trabalho foi estudar os efeitos da aflatoxina B1 (AFB1 sobre as vísceras (fígado, baço e moela de codornas poedeiras japonesas, em condições de exposição a baixas doses, tendo em vista que são poucos os dados de toxicidade de longa duração nesta espécie. Assim, foram constituídos 4 grupos formados, cada um, por 6 codornas de linhagem comercial, as quais receberam rações contendo AFB1 nas concentrações de 0 (controle, 25, 50 e 100mg.kg-1, durante 168 dias. As aves do grupo 100mg kg_1 apresentaram fígados com peso relativo médio menor (p The aim of the present record was to study the effects of aflatoxin B1 (AFB1 on selected viscera (liver, spleen and gizzard of laying Japanese quail under conditions of low level exposure, in view of the little information regarding the long term toxicity on this specie. Thus, four experimental groups of six commercial quails were constituted and given rations containing either 0 (controls, 25, 50 or 100mg aflatoxin B1 (AFB1/kg feed, during 168 days. When compared to controls, birds from group 100mg.kg-1 presented low relative liver weight (p < 0.05. Histological changes were observed only in the livers, and all samples from quail exposed to AFB1 revealed moderate to severe hepatic cell vacuolation with fatty change, particularly in birds from groups receiving highest levels of toxin (50 and 100mg.kg-1. Bile duct hyperplasia occurred only in the birds exposed to 100mg.kg-1 of AFB1. The results indicated that long term administration of AFB1 at levels above 50mg.kg-1 can cause significant hepatic lesions in Japanese quail.

    Abstract: This article explores the dynamics of the ‘spectre’ or ‘spectral body’ of the auteurist figure of Agnès Varda, as a means of discussing the ethical practices of mourning and memorial in two of Varda’s recent moving image works. It further elaborates on the motifs of ‘spectral bodies’ and ‘temporalised spaces’ to negotiate memorial practices between and across film viewing, filmmaking and the filmmaker. It does so using two interrelated projects by Varda; one in the realm of the plastic arts (her exhibition of 2006 entitled L’Île et elle, with a particular focus on the installation Les Veuves de Noirmoutier (The Widows of Noirmoutier, 2005 and the other in film format for cinema distribution, her most recent film, Les Plages D’Agnès (The Beaches of Agnès, 2008. Drawing upon Jacques Derrida’s notion of the spectral return, or revenant, specifically in audio-visual media, I examine the processes of spectral embodiment and motile mourning at work in these autobiographical projects. The article concludes by reflecting upon the ethical possibilities of productive nostalgia and repetitive mourning, and how these gestures and sites of longing and bereavement offer an open and ludic space for shared flows and communities of affect and memory between filmmakers, artworks and audiences.

    Mourning is predominantly understood as an emotional process caused by the loss of a beloved other. This assumption is challenged by this article on Hervé Guibert’s 1990 documentary La Pudeur ou l’impudeur in which the author and photographer represents his physical and emotional suffering through the last stages of AIDS. The article explores this suffering via the idea of ‘self mourning’ which denotes the subject’s reflection on his own mortality and which as the author proposes is part of e...
