    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.

    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.

    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.

    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.

    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.

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 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.

    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.

    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.

    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.

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

    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

    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%.

    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

    A total number of 360 Japanese quail (14 days old) were used to study the effect of using 2% garlic as a supplement in order to overcome the adverse effect of adding 4% heated oil on their meat and egg quality. The chicks were equally and randomly arranged into 4 groups, each of three replicates. The first and second groups were supplemented with 4% cotton seed oil and 4% cotton seed oil + 2% garlic, respectively, while in both third and forth groups, cotton seed oil was replaced by 4% heated oil. The body weight and mortality rate were examined weekly. At 42 day of age, 9 birds from each group were slaughtered. Serum cholesterol, triglycerides, T3 and T4 were determined by RIA besides to cholesterol and fatty acid in meat. The experiment was completed with the remaining chicks for another 6 weeks for analysis of egg cholesterol, triglyceride and fatty acids. The data revealed that addition of 2% garlic to both cotton seed and heated oil significantly decreased serum and egg cholesterol and triglycerides and meat cholesterol. In addition, total unsaturated fatty acid showed improvement in both meat and egg

    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 Due to its high concentration of polyunsaturated fatty acids, poultry meat is prone to oxidative deterioration. The aim of this study was to investigate the effect of essential oils of thyme, oregano and their combination in comparison with virginiamycin on quality of quail’s meat. The dietary treatments consisted of the basal control (without any added compounds or with 100 mg/kg of virginiamycin, 100 and 200 mg/kg of thyme and oregano essential oils, as well as an equal mixture of thyme and oregano essential oil (levels of 50 and 100 mg /kg.  At the end of 35 days of the experiment, two birds from each group were slaughtered for testing the meat quality (including malondialdehyde, pH, water holding capacity, dripping loss and cooking loss. Results showed that essential oils of thyme, oregano and their mixture reduced the thiobarbituric acid value, dripping loss and cooking loss; on the other hand pH value and water holding capacity was increased. Oregano and thyme essential oils contain compounds with high antioxidant properties. Therefore, the presence of these compounds in the bloodstream and their accumulation in the muscle tissue could results in an increase in the antioxidant capacity and consequently enhance the keeping quality of meat. It seems that the application of natural antioxidants such as thymol or carvacrol could be helpful to improve the quality of poultry meat.

    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.

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

    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.

    Estonia is situated on the eastern coast of the Baltic Sea. This is a region with intensive cyclonic activity and therefore with a relatively high mean wind speed. Atmospheric circulation and its seasonal variation determine the general character of the Estonian wind regime over the Atlantic Ocean and Eurasia. However, the Baltic sea itself is a very important factor affecting wind climate, it has an especially strong influence on the wind regime in costal areas. The mean energy density (W/m 2 ) is a wind energy characteristic that is proportional to the third power of wind speed and describes energy available in a flow of air through a unit area. The mean energy density is a characteristic which has practical importance in regional assessment of snowdrift, storm damage and wind energy

    Energy policy, environmental protection and economy form a triangle of tightly linked sectors, and any solution of some energy problem can be solved only in the light of all the above mentioned factors. There are several energy master plans for Estonia, the first of them dating back to the years of the Soviet Union and ending the list with the plan to cover the years up to 2000. By now the basic principles of the Estonian energy policy have been prepared and Estonian Energy Concept is being worked out. The main goal of Estonian energy policy is ensure an effective and environmentally benign energy supply for the country. It means safety in energy supply, effective production and supply together with sufficient environmental protection. Energy Council in the role of an advisory voluntary organization for inspection of the energy system and finding measures to improve its efficiency is established with parliament members included. The Estonian Energy Research Institute and the Oil--Shale Research Institute serve as a scientific advisory board for the government in energy policy. It's important to emphasise that privatisation is no panacea, solving all the problems, and therefore we are facing hard to move in the right direction, satisfying all the consumers of energy

    Full Text Available The article describes logistics survey in Estonia carried out in 2007 as a part of the LogOnBaltic project. The level of logistics in Estonian manufacturing, trading and logistics companies is explored through logistics costs, performance indicators, outsourcing, ICT use and logistics self-estimation of the companies responded. Responses from 186 Estonian companies were gathered through a web-based survey (38% of manufacturing, 38% of trading and 24% of logistics sector. Logistics costs as the percentage of turnover make in average 13.8% in manufacturing and 13.3% in trading. Transportation and inventory carrying cost form around 70% of overall logistics costs. Considering the logistics indicators surveyed, Estonian companies show up with relatively low perfect order fulfillment rates, short customer order fulfillment cycles and effective management of cash flows. The most widely outsourced logistics function is international transportation followed by domestic transportation, freight forwarding and reverse logistics. By 2010, the outsourcing of IT systems in logistics followed by inventory management, warehousing and product customization is expected to increase more substantially. The awareness of logistics importance is still low among Estonian companies. Only 27–44% of those agree that logistics has a considerable impact on profitability, competitive advantage, top management or customer service level.

    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.

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.

    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.

    2013-06-01

    Full Text Available The article examines the cultural situation following postmodernism in the first decade of the 21st century. To characterise this situation, the umbrella term “post-postmodernism” is used, as well as “neomodernism”, “altermodern”, “metamodernism”, “hypermodernity”, “performatism”, “critical realism” etc. All these approaches are, in a wider sense, united by their aim of opposing postmodernist cynicism and irony, and bringing back truth, simplicity and clarity. It has also been found that literature has returned or is returning to realism, and various cultural phenomena are emerging, which have been designated by the concept “new sincerity”.In descriptions of the current cultural situation, this trend seeking truth and simplicity is supported by approaches which emphasise the significance of technological developments during the last decade. A prominent figure here is Alan Kirby, who launched the term “digimodernism”, mainly linked with the adaptation and spread of Web 2.0 at the beginning of the 21st century: the blogosphere, Wikipedia, Twitter and Facebook.The article seeks answers to the question of whether we can talk about digimodernism in Estonian literature in the 2000s. In the 1990s Estonian writers were quite reluctant to undertake computer-technological experiments, and there are only a few examples of Estonian digital literature, whereas a change occurred in the 2000s. Many Estonian writers have had and still have their own blogs and surprisingly many have joined Facebook. The term “twitterature” is also familiar to Estonian writers. The article tackles the dominant topics in the blogs of Estonian writers and analyses their possible collective creative work on Facebook. A question is raised as to whether it is possible that the fragmentary narrative structure of blogs and Facebook has influenced mainstream literature.The article concludes that one essential change in Estonian literature in the

Design/methodology/approach – The sample includes participants from different levels of the Estonian Defence Forces (EDF military hierarchy (N=2570. The structure of the TLS was examined by using exploratory and confirmatory factor analyses. Additionally ANOVA was used to compare the results between different subsamples. Findings – TLS showed satisfactory reliability. Confirmatory factor analyses found TLS as valid five dimensions instrument to measure transformational leadership in the Estonian military context. Different management levels showed different emphases among the dimensions of transformational leadership. Research and practical limitations/implications – TLS will be an important tool to use in transformational leadership research in the Estonian military context and beyond. Additionally, the current research contributes to the development of alternative measurement tools besides the most commonly used MLQ. The limitation of the work will be the rather homogenous sample from the Estonian military, however it will open the door for the subsequent research using different samplings. Originality/value – The current research found TLS to be a reliable and valid instrument, very short and therefore easy to administrate, having the possibility to use it with five dimensional and as one general transformational instrument as well.

    The Organization of Estonian energetic economy is aimed at cutting the usage of oil, gas and coal and increasing the local resources firewood, oil-shale and peat for fuel. The resources of low-valued firewood-brushwood, fallen deadwood etc. are available during the following 10-15 years, but in the future the cultivation of energy forest (willow) plantations will be actual. During the last 20 years the Swedish scientists have been extensively studying the willow forest selection, cultivation and use in energetics and waste water purification systems. A Swedish-Estonian energy forest research project was started in 1993 between the Swedish Agricultural University on one hand and Toravere Observatory, Institute of Zoology and Botany, Estonian Academy of Sciences and Estonian Potato Processing Association on the other hand. In spring 5 willow plantations were established with the help of Swedish colleagues and obtained from Sweden 36000 willow cuttings. The aim of the project: a) To study experimentally and by means of mathematical modelling the biogeophysical aspects of growth and productivity of willow plantations in Sweden and Estonian climatological conditions. b) To study the possibility of using the willow plantations in waste waters purification. c) To study the economical efficiency of energy forest as an energy resource under the economic and environmental conditions of Estonia. d) To study the economic efficiency of willow plantations as a raw material for the basket industry in Estonia. e) To select the most productive and least vulnerable willow clones for practical application in energy plantations. During 1993 in all five plantations detailed analysis of soil properties has been carried out. In the plantation at Toravere Observatory phytometrical measurements were carried out - the growth of plant biomass leaf and stem area, vertical distribution of dry matter content, biomass and phyto area separately for leaves and stems has been performed.

    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.

    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

    Flue gas emissions from pulverized oil shale fired boilers of Estonian and Baltic power plants have been studied. The concentrations of NO x , CO, C x H y , HCI, Hf and polycyclic aromatic hydrocarbons in flue gases have been found to be relatively low and acceptable according to German emission limits, for instance. Desulphurization degree of flue gases by SO 2 absorption with ash has been found to vary defending on boiler type and operation conditions. In spite of significant sulphur capture (average values for different boilers in the range between 68 and 77 % of the initial sulphur content of the fuel), SO 2 concentrations in flue gases remain still very high (up to 2600 mg/m 3 , 10% O 2 ). Very high concentrations of particles, especially at Estonian Power Plant (up o 6250 mg/m 3 , 10 % 0 2 ) have been detected. Heavy metal emissions were too high by the reason of particle control insufficiency as well. Yearly emission estimates of this study support the former Estonian ones within the range of 10-15 %.

    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 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.

    2000-01-01

    Due to global warming and environment pollution because of widespread use of fossil fuels there are already tendencies to stabilize and decrease the consumption of these energy resources and take into use more renewable energy resources. Estonian Biofuels Association (EBA) is a non-profit association, which was founded on 8. of May 1998 in Tallinn. The EBA is an independent and voluntary alliance of its members. Fields of activity of the EBA are by biofuels research, developing and evaluation to engage environmental, biofuels and energy saving. EBA members are: energy consultants, scientists, as well as fuel suppliers, DH-companies, technology suppliers, energy service companies etc. The members of EBA are involved in different projects in Estonia, where biomass are produced and used for heating, where wood, waste, peat, rape oil and biogas resources are examined and put into use, and also projects which deal with energy saving and environment friendly equipment production for using biofuels. During our short experience we have noticed that people in Estonia have become more aware of biomass and their use, so the development of environment friendly and sustainable energetics will continue in Estonia. Available biofuels in Estonia could compete with fossil fuels if burnt rationally with high technology equipment. EBA members are convinced that biomass have perspective and that they could play an important role in improving Estonian economic and environmental situation. Modem biomass combustion devices are taken into use more the faster general wealth increases and EBA can raise people's awareness of bio fuel subject through special, courses and media. We want Estonian energy policy to develop towards widespread use of renewable energy resources, which would save energy and environment improve nation's foreign trade balance and create jobs mainly in rural areas

    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.

At the same time, this problem was also studied in other segregated regions of Estonia: Kohtla-Järve and Maardu. According to the database of the population census from the year 2000 (Estonian Statistics Executive Office's census 2000, there are representatives of 142 ethnic groups living in Estonia, speaking a total of 109 native languages. At the same time, the database doesn’t state which languages are spoken at homes. The material presented in this article belongs to the research topic “Home Language of Basic School Students in Tallinn” from years 2007–2008, specifically financed and ordered by the Estonian Ministry of Education and Research (grant No. ETF 7065 in the framework of an international study called “Multilingual Project”. It was determined what language is dominating in everyday use, what are the factors for choosing the language for communication, what are the preferred languages and language skills. This study reflects the actual trends of the language situation in these cities.

    1996-12-31

    In the end of the Soviet period in the 1980s, a long-term energy programme for Estonia was worked out. The energy system was planned to be based on nuclear power and the share of domestic alternative sources of energy was low. The situation has greatly changed after the re-establishment of the Estonian independence, and now wood and peat fuels play an important role in the energy system. Energy consumption in Estonia decreased during the period 1970-1993, but this process has less influenced the consumption of domestic renewable fuels - peat and wood. It means that the share of these fuels has grown. The investment on substitution of imported fossil fuels and on conversion of boiler plants from fossil fuels to domestic fuels has reached the level of USD 100 million. The perspectives of the wood energy depend mainly on two factors; the resources and the price of wood energy compared with other fuels. The situation in wood market influences both the possible quantities and the price. It is typical that the quickly growing cost of labour power in Estonia is greatly affecting the price of energy wood. Though the price level of fuel peat and wood chips is lower than the world market price today, the conditions for using biofuels could be more favourable, if higher environmental fees were introduced. In conjunction with increasing utilisation of biofuels it is important to evaluate possible emissions or removal of greenhouse gases from Estonian forests 3 refs.

    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.

    2017-12-01

    Full Text Available Since its independence in 1991 Estonia has successfully overpassed the challenges of the transition period being in the present of one the most technologically developed nations of Europe. The present research is intended to evaluate the relationship between Estonian pro-market regulation, entrepreneurship and innovation. In order to reach relevant conclusions in this regard there have been used both qualitative and quantitative methods of analysis. In such a way, it could be comprehensively reviewed the process of Estonian economic development from a relatively underdeveloped USSR republic to an advanced innovation driven economy. The results show that pro-market governmental regulation has favourably influenced Estonian entrepreneurship, while it fostered country’s innovation capacities. It has been concluded that the economic “miracle” of Estonia has been at a great extent determined by proper government regulation oriented towards economic liberalisation.

    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.

    A method utilizing PCR-restriction fragment length polymorphism (RFLP) in the mitochondrial genes was developed for beef (Bos taurus), pork (Sus scrofa), buffalo (Bubalus bubali), quail (Coturnix coturnix), chicken (Gallus gallus), goat (Capra hircus), rabbit (Oryctolagus cuniculus) species identification and Halal authentication. PCR products of 359-bp were successfully obtained from the cyt b gene of these six meats. AluI, BsaJI, RsaI, MseI, and BstUI enzymes were identified as potential restriction endonucleases to differentiate the meats. The genetic differences within the cyt b gene among the meat were successfully confirmed by PCR-RFLP. A reliable typing scheme of species which revealed the genetic differences among the species was developed.

    Bobwhite quail chicks, when given a choice of balanced diets in which the essential difference was the protein supplement, showed preferences for one diet containing 49 per cent peanut oil meal, another containing a mixture of 9 per cent meat and bone scraps (50% protein) with 38 per cent soybean oil meal, and a third (control) diet containing a mixture of 16 per cent dried buttermilk with 42 per cent soybean oil meal, in contrast to diets containing sardine meal or menhaden fish meal. ....Feeding tests during the first five weeks of life showed that diets containing 14 per cent sardine fish meal consistently gave high live weights, low mortality, and high efficiency of feed utilization. Diets with 9 to 10 per cent menhaden meal produced nearly as good results....Live weights, survival, and efficiency of feed utilization were markedly better on a diet containing 9 per cent meat and bone scrap (50% protein) than on one with 9 per cent meat scrap (55% protein), but not as good as with diets containing fish meal without meat....The chicks grew and survived more successfully on diets containing either soybean oil meal or peanut oil meal as the sole protein supplement, than on diets containing either linseed oil meal, cottonseed oil meal, or dried buttermilk as the sole protein concentrate. None of these was as satisfactory as the diets containing fish meal.....All chicks died on diets containing either linseed oil meal, cottonseed oil meal, or dried buttermilk as the sole source of protein. All three of these concentrates, however, gave satisfactory results, when used as 10 per cent of the diet. In fact, survival and efficiency of feed utilization were nearly as good on a diet containing 10 per cent dried buttermilk, 10 per cent linseed oil meal, 10 per cent peanut oil meal, and 27 per cent soybean oil meal, as on diets containing fish meal.

    Full Text Available The study was focussed on the relationships between ethnic self-esteem and various indicators of intergroup attitudes in a representative sample of adult population of Estonia (N=1142. Attitudinal variables that discriminated most between persons with high and low ethnic self-esteem were identified. Among Estonians ethnic self-esteem was related to positive ingroup bias, readiness for outgroup contact, perceived threat from the outgroup, attitudes to non-Estonian minority, and attitudes toward minority integration. Among non-Estonians ethnic self-esteem was related to readiness for outgroup contact, ethnic sterotypes, and various attitudes towards minority integration. An attempt was made to reconstruct the system of intergroup attidues of prototypical persons with high and low ethnic selfesteem and to describe psychological implications of high and low ethnic self-esteem for members of majority and minority groups. Various theoretical models (social identity theory, integrated threat theory, social dominane theory were used for interpretation of the results.

  20. Meat flavour

    International Nuclear Information System (INIS)

    Rosset, R.; Liger, P.; Roussel-Ciquard, N.

    1978-01-01

    For the consumer, meat is characterized by a certain number of organoleptic qualities; among them, flavour -that is to say the association of both odour and taste- plays a leading part. This property is based upon a great number of chemical components: some volatile components are responsible for the aroma and some non-volatile ones for the taste. These substances are either made or released during the heating of the meat on account of components called precursors which are produced during the aging of the meat. The two main reactions which preside over the elaboration of flavour are: the Maillard's reaction and the autooxidation reactions. Meat flavour is associated with the animal characteristics; it is influenced by the ante- and post mortem treatments as well as by the technological treatments for storing it. The use of synthetical flavours is to be considered as possible in the future [fr

  1. Factors influencing methionine toxicity in young bobwhite quail

    Serafin, J.A.

    1981-01-01

    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.

    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.

    Full Text Available The aim of this study was the estimation of digestible lysine requirements of Japanese quail during the 7-21d period. Graduation level of L-lysine.HCL were added to the basal diet at the expense of corn starch to create different levels of digestible lysine ranged from 0.75 to 1.35% of diet. Growth performance and carcass composition were evaluated during the experiment. The results showed that incremental levels of digestible lysine significantly affected the body weight gain (BWG, feed conversion ratio (FCR, feed intake (FI, breast meat yield (BMY and thigh meat yield (TMY. Either linear broken- line or quadratic broken line model were used to get break points of digestible lysine as a requirement. Based on linear broken line analysis, the break points for FCR and BMY were 0.99 and 1.04 % of diet, respectively. Using the quadratic broken-line model, the estimated Lys requirements for BWG, FCR, and BMY were 1.11, 1.04, and 1.15% of diet, respectively. The results showed that the Lys needs for optimum BMY was higher than BWG and FCR.

    A PCR assay was developed for the identification of meats and commercial meat products from quail (Coturnix coturnix), pheasant (Phasianus colchicus), partridge (Alectoris spp.), guinea fowl (Numida meleagris), pigeon (Columba spp.), Eurasian woodcock (Scolopax rusticola), and song thrush (Turdus philomelos) based on oligonucleotide primers targeting specific sequences from the mitochondrial D-loop region. The primers designed generated specific fragments of 96, 100, 104, 106, 147, 127, and 154 bp in length for quail, pheasant, partridge, guinea fowl, pigeon, Eurasian woodcock, and song thrush tissues, respectively. The specificity of each primer pair was tested against DNA from various game and domestic species. In this work, satisfactory amplification was accomplished in the analysis of experimentally pasteurized (72 degrees C for 30 min) and sterilized (121 degrees C for 20 min) meats, as well as in commercial meat products from the target species. The technique was also applied to raw and sterilized muscular binary mixtures, with a detection limit of 0.1% (wt/wt) for each of the targeted species. The proposed PCR assay represents a rapid and straightforward method for the detection of possible mislabeling in game bird meat products.

    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

    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.

    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...

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

    Directory of Open Access Journals (Sweden)

    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.

    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.

  18. Spontaneous, Experimentally Induced, and Transmissible AA Amyloidosis in Japanese Quail ( Coturnix japonica).

    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.

    Diet has health consequences, which makes knowing the psychological correlates of dietary habits important. Associations between dietary habits and personality traits were examined in a large sample of Estonians (N = 1,691) aged between 18 and 89 years. Dietary habits were measured using 11 items, which grouped into two factors reflecting (a) health aware and (b) traditional dietary patterns. The health aware diet factor was defined by eating more cereal and dairy products, fish, vegetables and fruits. The traditional diet factor was defined by eating more potatoes, meat and meat products, and bread. Personality was assessed by participants themselves and by people who knew them well. The questionnaire used was the NEO Personality Inventory-3, which measures the Five-Factor Model personality broad traits of Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness, along with six facets for each trait. Gender, age and educational level were controlled for. Higher scores on the health aware diet factor were associated with lower Neuroticism, and higher Extraversion, Openness and Conscientiousness (effect sizes were modest: r = .11 to 0.17 in self-ratings, and r = .08 to 0.11 in informant-ratings, ps < 0.01 or lower). Higher scores on the traditional diet factor were related to lower levels of Openness (r = -0.14 and -0.13, p < .001, self- and informant-ratings, respectively). Endorsement of healthy and avoidance of traditional dietary items are associated with people's personality trait levels, especially higher Openness. The results may inform dietary interventions with respect to possible barriers to diet change.

    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 most comprehensive epidemiological project ever performed in Estonia - The Estonian Study of Chernobyl Cleanup Workers - was the joint effort of researchers from Estonia, Finland and USA. Until September 1999, the results of this study were published in English only. To familiarize the readership of 'Eesti Arst' with the major study findings, the abridged versions of four original papers from 'Radiation Research' are presented in the current issue of the journal. For the Estonian epidemiologists, the work under this project that consists of eight sub projects was a real challenge. In the course of the study, skills were developed in writing a study protocol, preparing a questionnaire, progress reporting, documenting the structure of databases, record linkage, and problem solving. It was an exciting experience to work with top scientists like William Bigbee, John Boice, Timo Hakulinen, Ronald Jensen and Gayle Littlefield. (author)

Data were collected by interviews with 27 managers and engineers from 16 manufacturing companies in various industries. Most of the critical success factors taken up were related to marketing, information management, quality management, product development and technological innovations. The information needs of managers and engineers were related to competitors, customers, markets, technology, regulations, etc. Some identified CSFs expressed also priorities for development by Estonian economic authorities: to support the implementation of new technologies and introduction of quality management methods. The finding that information management was perceived as a very critical area supports the result of the recent Finnish study on CSFs.

    Full Text Available The aim of this study is to analyse the efficiency of Estonian grain farms after Estonia’s transition to a market economy and during the accession period to the European Union (EU. The non-parametric method Data Envelopment Analysis (DEA was used to estimate the total technical, pure technical and scale efficiency of Estonian grain farms in 2000–2004. Mean total technical efficiency varied from 0.70 to 0.78. Of the grain farms 62% are operating under increasing returns to scale. Solely based on the DEA model it is not possible to determine optimum farm scale and the range of Estonian farm sizes operating efficiently is extensive. The most pure technically efficient farms were the smallest and the largest but the productivity of small farms is low compared to larger farms because of their small scale. Therefore, they are the least competitive. Since pre-accession period to the EU, large input slacks of capital have replaced the former excessive use of labour and land. This raises the question about the effects on efficiency of the EU’s investment support schemes in new member states.;

  16. Revisiting the Estonian Cyber Attacks: Digital Threats and Multinational Responses

    2011-01-01

    Full Text Available In April 2007, the Estonian Government moved a memorial commemorating the Soviet liberation of the country from the Nazis to a less prominent and visible location in Tallinn. This decision triggered rioting among Russian-speaking minorities and cyber terrorism targeting Estonia's critical economic and political infrastructure. Drawing upon the Estonian cyber attacks, this article argues that globalization and the Internet have enabled transnational groups—such as the Russian diaspora—to avenge their grievances by threatening the sovereignty of nation-states in cyberspace. Sophisticated and virtually untraceable political "hacktivists" may now possess the ability to disrupt or destroy government operations, banking transactions, city power grids, and even military weapon systems. Fortunately, western countries banded together to effectively combat the Estonian cyber attacks and minimize their effects. However, this article concludes that in the age of globalization, interdependence, and digital interconnectedness, nation-states must engage in increased cooperative cyber-defense activities to counter and prevent devastating Internet attacks and their implications.

    2010-12-01

    Full Text Available The article examines the exiled Estonian politicians in the European Movement in the early Cold War period. The ultimate goal of exiled Estonians was to restore their state’s independence. In order to promote this, Estonian leaders sought connections with Western leaders. The European Movement was the only organisation involving actors from both the East and the West, and this corresponded to the Estonian discourse on Europe as a whole. Therefore, the European Movement was appreciated, although its limited opportunities for decisive actions were also recognised. East and West European interest in the European Movement declined as West European integration rapidly intensified through the European Coal and Steel Community (ECSC and particularly after the January 1952 Eastern European Conference in London. By 1957, disappointment in the inability of European unification to help regain Estonian independence became evident.

  20. Influence of protein level and supplemental methionine in practical rations for young endangered masked bobwhite quail

    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.

    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.

    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.

    Listeria and particularly Listeria monocytogenes are important foodborne pathogens that can cause listeriosis and severe complications in immunocompromised individuals, children, pregnant women, and the elderly. The objective of this study was to determine the prevalence of Listeria spp. in raw meat in Iran. From July 2010 to November 2011, a total of 1,107 samples of various raw meats were obtained from randomly selected retail butcher shops. The results of conventional bacteriologic and PCR methods revealed that 141 samples (12.7%) were positive for Listeria spp. The highest prevalence of Listeria was found in raw buffalo meat samples (7 of 24 samples; 29.2%) followed by quail meat (26 of 116 samples; 22.4%), partridge meat (13 of 74 samples; 17.6%), and chicken meat (27 of 160 samples; 16.9%). The most common species recovered was Listeria innocua (98 of 141 strains; 75.9 % ); the remaining isolates were L. monocytogenes (19.1% of strains), Listeria welshimeri (6.4% of strains), Listeria seeligeri (3.5% of strains), and Listeria grayi (1.4% of strains). Susceptibilities of the 141 strains to 11 antimicrobial drugs were determined using the disk diffusion assay. Overall, 104 (73.8%) of the Listeria isolates were resistant to one or more antimicrobials, and 17.0% of the isolates were resistant to three or more antimicrobials. The present study provides the first baseline data on the prevalence of Listeria in raw meat derived from sheep, goat, buffalo, quail, partridge, chicken, and ostrich in Iran and the susceptibility of these isolates to antimicrobials.

    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.

    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.

  8. 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.

    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.

  10. Egg-laying substrate selection for optimal camouflage by quail.

    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.

  11. Estonian Language of Technology as a Factor Supporting the Evolution of Engineering Thinking

    Directory of Open Access Journals (Sweden)

    Mägi, Vahur

    2013-03-01

    Full Text Available Casual mention of teaching technology subjects in Estonian schools dates back several centuries. Navigation and construction were amongthe earliest professional skills that were taught. As both of them required mathematical thinking skills, teaching the subjects was usually accompanied by explaining the principles of mathematics. The first technology book in Estonian was published about two centuries ago and it dealed with geodesy. The earliest Estonian glossaries of technological terminology were published in the fields of physics and chemistry. The rise of Estonian as a language of higher education and science in the country came about in the 1920s and 1930s. Faculty members of the Tallinn School of Technology then published the first textbooks composed in the Estonian language for students of technology. The Estonian Society for Technology and the Estonian Association of Engineers became seriously involved in linguistic activities. Together with the Vocational Teachers’ Assembly of Tartu they published an illustrated technology glossary for machinery and tools terms. It was followed by a glossary of construction and building terms, compiled under the lead of the University of Technology. In addition, journals of technology introducedinnovations in the lexicon of technology to the general public. The postwar period in the development of the lexicon of technical terms was of little significance at first. A surge in language creativity could be detected in the 1960s, when terminology became a target of constantly growing attention to the development of technology lexicon. Series of technology glossaries were published. This tendency has continued to this day.

  12. 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

    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.

    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.

    2005-05-01

    This study examined the smoking habits and attitudes towards smoking among Estonian physicians. Cross-sectional data for 2668 physicians were gathered by a self-administered postal survey. The current smoking prevalence was 24.9% for male physicians and 10.8% for female physicians. The percentages of ex-smokers were 32.9 and 16.8%, respectively. Smoking prevalence among physicians was below the levels reported for the highest educational bracket of the total population in Estonia. Non-smoking physicians had more unfavourable views towards smoking than those who smoked. The majority of physicians were aware of the association between smoking and various diseases, with significant differences between smokers and non-smokers. Non-smoking physicians were more active in asking patients about smoking habits than those who smoked. Most Estonian physicians, especially those who smoked, failed to perceive themselves as positive role models. This study found a lower prevalence of smoking among physicians compared with the general population, and demonstrated the impact of personal smoking on physicians' attitudes towards smoking. The results provide an important challenge to medical education in Estonia.

    Full Text Available Economic weights for milk carrier (water plus lactose, fat and protein yields, calving interval, age at first service, interval between the first service and conception of heifers and length of productive life of Estonian Holsteins were estimated under assumed milk production quota and for non-quota conditions. A bio-economic model of an integrated production system of a closed herd was used. Economic values of milk carrier yield and length of productive life differed between quota and non-quota conditions, but there were only minor differences between those marketing systems in economic values for functional traits. The standardised economic values of the most important traits varied in magnitude between18 to 81% of the economic value for milk yield. Discounting had a substantial impact on the economic value of length of productive life. When defining the breeding objective for Estonian Holstein, the interval between the first service and conception of heifers, and the length of productive life should be included in the breeding goal along with the traits with the highest economic value, milk, fat and protein yield. In the optimum breeding objective, relative weights of production vs. functional traits were 79 and 21%, respectively.;

  19. Acquisition of noun derivation in Estonian and Russian L1

    Reili Argus

    2018-04-01

    Full Text Available Acquisition of derivation is not a well-studied area in first language research and a comparative approach to the acquisition of derivation in different languages doesn’t exist. There is no information on how a child acquires derivation in a language with a rich and regular system of derivational patterns, or in a language where derivation is productive, but the system of derivational patterns is opaque. According to general ideas of complexity in a language, the child should start to use simplex stems first and, only after that, complex ones, that is, complexity should increase in the course of acquisition. Our paper is intended to address these issues, based on longitudinal child data from typologically different languages, Estonian and Russian. The results revealed significant differences in the acquisition of noun derivation in the two languages under observation. The system of noun derivation is acquired at a faster pace in Russian, while Estonian children have far fewer noun derivatives in their speech and they use different derivation suffixes with less regularity. Even so, the so-called building block model may be applied for both languages only partially.

  20. Estonian horticultural peat marketing: sales promotion and price formation. 2. part

    1999-01-01

    When forming prices, Estonian peat companies' decisions should be based on marginal cost analysis. Unfortunately most Estonian companies sell peat to intermediaries and cannot influence its price. Estonian peat producers have to choose between either selling peat directly or selling through a central marketing organization. Both systems have their pros and cons. Direct selling gives more freedom to individual producers but is more risky. Central marketing makes cost saving possible and is more effective and stable, but may alienate producers from clients and markets. Whichever marketing system Estonian peat companies choose, the most important elements in their marketing strategy should be: careful market analysis, personal sales, attending trade shows, catalogues, quality service and offering transportation services.

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.

    The objective of the present study was to examine the effects of hydrocolloidal silver nanoparticles (Ag-nano) on microbial profile of caecum and morphology of enterocytes in duodenum of Japanese quail, as a model animal for poultry. Quails (Coturnix coturnix japonica) (10 d old) were randomly...... killed and samples of duodenum and caeca microflora were collected. This initial investigation demonstrated that silver nanoparticles did not influence emphatically microflora of quail caecum; however, water containing 25 mg/kg of Ag-nano significantly increased the population of lactic acid bacteria...

    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.

    Lipid oxidation is one of the main factors limiting the quality and acceptability of meats and meat products. Oxidative damage to lipids occurs in the living animal because of an imbalance between the production of reactive oxygen species and the animal's defence mechanisms. This may be brought about by a high intake of oxidized lipids or poly-unsaturated fatty acids, or a low intake of nutrients involved in the antioxidant defence system. Damage to lipids may be accentuated in the immediate post-slaughter period and, in particular, during handling, processing, storage and cooking. In recent years, pressure to reduce artificial additive use in foods has led to attempts to increase meat stability by dietary strategies. These include supplementation of animal diets with vitamin E, ascorbic acid, or carotenoids, or withdrawal of trace mineral supplements. Dietary vitamin E supplementation reduces lipid and myoglobin oxidation, and, in certain situations, drip losses in meats. However, vitamin C supplementation appears to have little, if any, beneficial effects on meat stability. The effect of feeding higher levels of carotenoids on meat stability requires further study. Some studies have demonstrated that reducing the iron and copper content of feeds improves meat stability. Post-slaughter carnosine addition may be an effective means of improving lipid stability in processed meats, perhaps in combination with dietary vitamin E supplementation.

    Full Text Available Recession has sharply erected the question of tax burden and the optimal proportion of different kinds of taxes among the incomes of the budget. Indirect taxes and consumption taxes, which proportion is different according to different methodologies, dominate in Estonian state budget. The buoyancy of a tax system based on taxes of that kind is especially weak during the recession. Difficulties concerning the incomes of budget have arisen the necessity for lifting taxes, which is possible as the tax burden is low now. But a sharp question of the optimal level of taxes is going to be raised. A formula for indirect tax optimum according to Ramsey taxes and Slutski decomposition has been proposed in the article.

    to the dietary supplementation of FFS at 15% level. The breast meat yield decreased due to dietary supplementation of FFS at 10% and 15% level in the diet of broiler Japanese quails. The effect of FFS was found to be nonsignificant (p>0.05 with respect to serum total protein, globulin and A/G ratio under different treatments whereas significant difference observed in serum albumin concentration. Dietary supplementation of FFS at 10% and 15% level significantly increased the AST concentration in serum. There was no significant difference among the treatments regarding the parameters such as ALT, calcium, phosphorous, triglyceride, total cholesterol, HDL-C, VLDL-C, and LDL-C. Conclusion: The serum-biochemical parameters are influenced by the dietary supplementation of FFS in broiler Japanese quails.

  10. 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.

    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.

    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.

    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.

    The health-conscious consumers are in search of nutritious and convenient food item which can be best suited in their busy life. The vegetarianism is the key for the search of such food which resembles the meat in respect of nutrition and sensory characters, but not of animal origin and contains vegetable or its modified form, this is the point when meat analog evolved out and gets shape. The consumers gets full satisfaction by consumption of meat analog due to its typical meaty texture, appearance and the flavor which are being imparted during the skilled production of meat analog. The supplement of protein in vegetarian diet through meat alike food can be fulfilled by incorporating protein-rich vegetative food grade materials in meat analog and by adopting proper technological process which can promote the proper fabrication of meat analog with acceptable meat like texture, appearance, flavor, etc. The easily available vegetables, cereals, and pulses in India have great advantages and prospects to be used in food products and it can improve the nutritional and functional characters of the food items. The various form and functional characters of food items are available world over and attracts the meat technologists and the food processors to bring some innovativeness in meat analog and its presentation and marketability so that the acceptability of meat analog can be overgrown by the consumers.

    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

    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.

    2011-03-01

    Full Text Available The article examines how folk calendar holidays are represented in Estonian fairy tales. It introduces some views presented in folklore studies about the concept of time in fairy tales and finds parallels with them in the Estonian context. The analysis relies on the digital corpus of Estonian fairy tales (5400 variants, created from the texts found in the Estonian Folklore Archives by the Fairy Tale Project of the Department of Estonian and Comparative Folklore, University of Tartu. Folk calendar holidays occur in Estonian fairy tales relatively seldom; most often these are holidays that occupy a significant place in the Estonian folk calendar (Christmas, St. John’s Day, Easter, St. George’s Day. Calendar holidays are notably mentioned more often in tale types which remain on the borderline between the fairy tale and the legend or the fairy tale and the religious tale. In Estonian fairy tales, calendar holidays are used on three levels of meaning: (1 the holiday is organically associated with the tale type; it has an essential role in the plot of the tale; (2 to a certain extent, the holiday could be replaced by another holiday having an analogous meaning; (3 the holiday forms an unimportant or occasional addition to the tale.

    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

    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.

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

    Karine Isabela Tenório

    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.

    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)

    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.

    2005-03-01

    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.

  9. On the System of Place Name Signs in Estonian Sign Language

    Directory of Open Access Journals (Sweden)

    Liina Paales

    2011-05-01

    Full Text Available A place name sign is a linguistic-cultural marker that includes both memory and landscape. The author regards toponymic signs in Estonian Sign Language as representations of images held by the Estonian Deaf community: they reflect the geographical place, the period, the relationships of the Deaf community with hearing community, and the common and distinguishing features of the two cultures perceived by community's members. Name signs represent an element of signlore, which includes various types of creative linguistic play. There are stories hidden behind the place name signs that reveal the etymological origin of place name signs and reflect the community's memory. The purpose of this article is twofold. Firstly, it aims to introduce Estonian place name signs as Deaf signlore forms, analyse their structure and specify the main formation methods. Secondly, it interprets place-denoting signs in the light of understanding the foundations of Estonian Sign Language, Estonian Deaf education and education history, the traditions of local Deaf communities, and also of the cultural and local traditions of the dominant hearing communities. Both perspectives - linguistic and folkloristic - are represented in the current article.

    A countrywide survey of radon concentrations in Estonian dwellings was carried out during the period 1998-2001. The survey formed a part of the cooperation program on radiation protection between the Estonian Radiation Protection (Kiirguskeskus) Centre and the Swedish Radiation Protection Authority (SSI). The survey included measurements in a number of dwellings representative for Estonia in detached houses and multifamily buildings (only dwellings on the bottom floor were included in the survey). Altogether, radon concentrations were measured in 515 dwellings, a number large enough to be statistically significant. All measurements were made with alphatrack film detectors of the same type that SSI uses in Sweden. The measurements were made during a 2-3 month period during the winter half-year. Two detectors were used in each dwelling. In Estonia there are 0.17 million dwellings in detached houses and 0.45 million in multi apartment buildings. Of the 1.26 million inhabitants in Estonia. 0.36 million live in detached houses and 0.90 million in multi apartment buildings. Most of the latter were built during the Soviet occupation. Of the dwellings in multifamily buildings 30 % are assumed to be situated on the first floor. The mean radon concentration in dwellings in detached hoses, according to the survey results, is 103 Bq/m{sup 3}, in dwellings on the bottom floor in multi apartment buildings it is 78 Bq/m{sup 3}. In 1% of the dwellings the radon concentration exceeded 400 Bq/m{sup 3}. The highest radon concentration found in the study was 1040 Bq/m{sup 3}. Based on the assumption that the average radon concentration in the dwellings in multi-apartment buildings that are not situated on the bottom floor is 30 Bq/m{sup 3}, and that these dwellings constitute 70% of all dwellings in multi apartment buildings, the mean radon concentration in dwellings in multi apartment buildings is calculated to be 44 Bq/m{sup 3}. The mean value for all Estonia dwellings is calculated

    A countrywide survey of radon concentrations in Estonian dwellings was carried out during the period 1998-2001. The survey formed a part of the cooperation program on radiation protection between the Estonian Radiation Protection (Kiirguskeskus) Centre and the Swedish Radiation Protection Authority (SSI). The survey included measurements in a number of dwellings representative for Estonia in detached houses and multifamily buildings (only dwellings on the bottom floor were included in the survey). Altogether, radon concentrations were measured in 515 dwellings, a number large enough to be statistically significant. All measurements were made with alphatrack film detectors of the same type that SSI uses in Sweden. The measurements were made during a 2-3 month period during the winter half-year. Two detectors were used in each dwelling. In Estonia there are 0.17 million dwellings in detached houses and 0.45 million in multi apartment buildings. Of the 1.26 million inhabitants in Estonia. 0.36 million live in detached houses and 0.90 million in multi apartment buildings. Most of the latter were built during the Soviet occupation. Of the dwellings in multifamily buildings 30 % are assumed to be situated on the first floor. The mean radon concentration in dwellings in detached hoses, according to the survey results, is 103 Bq/m 3 , in dwellings on the bottom floor in multi apartment buildings it is 78 Bq/m 3 . In 1% of the dwellings the radon concentration exceeded 400 Bq/m 3 . The highest radon concentration found in the study was 1040 Bq/m 3 . Based on the assumption that the average radon concentration in the dwellings in multi-apartment buildings that are not situated on the bottom floor is 30 Bq/m 3 , and that these dwellings constitute 70% of all dwellings in multi apartment buildings, the mean radon concentration in dwellings in multi apartment buildings is calculated to be 44 Bq/m 3 . The mean value for all Estonia dwellings is calculated to be 60 Bq/m 3 . Using

    Full Text Available Examinations were conducted in terms of microbiological quality/quantity (TMC, Coliforms, E. coli, S. aureus, Sulphate-reducing Clostridia, B. cereus, Salmonella spp. and Lysteria spp. and Campylobacter spp. on 240 poultry meat samples (chicken, turkey and quail acquired pursuant to the standards set by the Regional Plan of programming and coordination in the field of operations concerning official inspections of Lombardia animal origin and by a few private companies for self-inspection. The TMC was consistently low and in line with reports in the literature, as was the case with coliforms, E. coli, S. aureus, sulphatereducing Clostrides and B. cereus. In the case of Salmonella spp., only 5 samples tested positive: one for S. typhimurium and one for S. enteritidis (chicken; only one sample from turkey tested positive for S. blokley, and two out of five samples analysed from quail tested positive result for S. typhimurium. About 3% of the samples analyzed tested positive for Listeria monocitogenes, but they were within the legal limits. Research on Campylobacter thermophiles has involved only 50 samples, of which only 5 have tested positive. These results confirm the high quality of hygiene and cleanliness of poultry meat, in accordance with that reported in the national literature and with respect to EU norms.

    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

    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.

    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.

    Full Text Available Meat is a high quality food due its higher protein content, besides to provide energy, vitamins particularly B complex, water and minerals, resulting in an appreciated food for humans. Even in same country, consumers search for different stuffs, since north consumers looks for meat cuts with fat and bone, whereas center-south consumers prefers fatless debones meat cuts. Modern consumers demand excellent appearance, color, taste and flavor in foods, microbiologically safe, minimal processed and curing salts, very nutritive and cheap. All these together in one single product are a hard challenge in the meat products area.

    2002-01-01

    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.

    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.

    Full Text Available The article analyses tale type The Woman as Wolf, which is one of the most popular folk tales in the Estonian Folklore Archives and is represented there both in the form of a fairy tale and in the form of a legend. The vast majority of the versions of The Woman as Wolf were written down in the first part of the 20th century within Estonia and where recorded from Estonians. The article introduces the content of the tale, the origin of the first records from the early 19th century, and the dissemination area of the tale, which remains outside Western Europe: apart from the Estonian versions there are Sami, Karelian, Vepsian, Livonian, Latvian, Lithuanian, Russian, Ukrainian and Belarusian versions. While in almost all the Estonian versions the main protagonist is transformed into a wolf, in most of the versions written down in other areas and ethnic groups, another animal or bird replaces the wolf. The author is of the opinion that the Finnic area is central to the distribution of the folk tale The Woman as Wolf. The animal the woman is transformed into in the plot would not have been a wolf in earlier times. The article provides an explanation why the wolf is predominant in Estonian written sources. For that purpose the ways in which the wolf and werewolf were perceived in earlier Estonian folk belief are introduced. At the end of the article interpretation of the folk tale is provided. The author states that the plot and some of the motifs found in this folk tale reflect the difficulties women had in submitting to the norms and values of patriarchal order within their society.

    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 proportion of total corneal thickness of the hen stroma, 82.6%, was more similar to that of the human than was the quail stroma, 72.5%. Within the hen stroma, the density of keratocytes, 8.57±1.49 per 5,000μm(2), was about half that in the quail stroma (Phen cornea, the stromal thickness and proportional similarity of the corneal layers with human cornea, the hen maybe better than the quail as an alternative species suitable for use in studies of corneal refractive surgery.

    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.

    Full Text Available The article concerns itself with the figure of the teacher in Estonian society. We do not concentrate on the educational system as a whole, but on one specific and crucial element in this apparatus - the teacher. We begin by offering a brief historical overview of the conditions of pedagogues in the 20th century before moving on to describe the adoption of neo-liberal free market policies since the 1990s and the effects these policies had and still have on education. Our main concern is to understand the teacher as an actor in power relations; to achieve this understanding we have selected as our examples 1 surveillance techniques in school environment that have direct relations to the state and the market; and 2 the 2012 educational workers' strike that made it quite clear that the teachers have been fixed to a position of wage workers. The overall and more abstract aim of the paper is to think about the social role of the teacher in Estonia.

    Full Text Available A theoretical model was developed to model the fate of two common pharmaceutical residues: diclofenac and ibuprofen in eight Estonian seaside cities that discharge their wastewaters directly into the Baltic Sea. The consumption rates of the active ingredients of diclofenac and ibuprofen from 2006-2014 were analysed. A decrease of 19.9% for diclofenac consumption and an increase of 14.1% for ibuprofen were found. The fate of diclofenac and ibuprofen were modelled by considering the human metabolism removal rate for pharmaceuticals, the removal rate of diclofenac and ibuprofen in activated sludge wastewater treatment plants (WWTP and annual flow rates. An average decrease from 1 to 0.8 µg/l (decrease of 20% for diclofenac and an increase from 11.4 to 13.4 µg/l (increase of 14.9% for ibuprofen for the concentration in the effluents of the WWTP were modelled. The model gives us a good overview about the theoretical concentrations of pharmaceutical residues in the environment and is helpful for evaluating environmental impacts.

  7. History of experimental psychology from an Estonian perspective.

    Allik, Jüri

    2007-11-01

    A short review of the development of experimental psychology from an Estonian perspective is presented. The first rector after the reopening of the University of Dorpat (Tartu) in 1802, Georg Friedrich Parrot (1767-1852) was interested in optical phenomena which he attempted to explain by introducing the concept of unconscious inferences, anticipating a similar theory proposed by Herman von Helmholtz 20 years later. One of the next rectors, Alfred Wilhelm Volkmann (1800-1878) was regarded by Edwin Boring as one of the founding fathers of the experimental psychology. Georg Wilhelm Struve (1793-1864) played an essential part in solving the problem of personal equations. Arthur Joachim von Oettingen (1836-1920) developed a theory of music harmony, which stimulated his student Wilhelm Friedrich Ostwald (1853-1932) to study colour harmony. Emil Kraepelin (1856-1926), the founder of modern psychiatry, is by far the most important experimental psychologist who has worked in Estonia. His successor Wladimir von Tchisch (1855-1922), another student of Wilhelm Wundt, continued Kraepelin's work in experimental psychology. The lives of Wolfgang Köhler (1887-1967), who was born in Reval (Tallinn), and Oswald Külpe (1862-1915), who graduated from the University of Dorpat, extended the link between the history of experimental psychology and Estonia. Karl Gustav Girgensohn (1875-1925), the founder of the Dorpat School of the psychology of religion, stretched the use of experimental methods to the study of religious experience.

    1993-01-01

    The disaster that happened at the Chernobyl nuclear power station in 1986 caused a sharp rise in radioactive pollution over an extensive area in the region of the Baltic Sea. To estimate the distribution and the concentration of Cs-137 and Sr-90 in Estonian ecosystems, samples of mushrooms, mosses, lichens and the upper horizons of soil were gathered from 63 test sites during 1991. We were particularly interested in the amounts of radionuclides in mushrooms because these are used as food by people. Dangerously high radionuclide concentrations were found in mushrooms gathered in North-East Estonia. Heightened concentrations were registered here and there all over the territory of Estonia, especially in mushrooms gathered in Central and South-Western Estonia. The Cs-137 content in mushrooms depends on its content in other components of the ecosystems, first and foremost on the concentrations of radiocaesium in mosses and litter, which, therefore, can be used as indicators in prognostication the radioactive pollution of mushrooms in a certain region. As Cs-137 migrates between various ecosystem components, it is necessary to check the radioactivity of the forest products used for food for still a number of years to come. The Sr-90 level was low in all the ecosystem components examined. (author). 3 figs., 10 refs

    HALL, H E; ANGELOTTI, R

    1965-05-01

    A total of 262 specimens of meat and meat dishes were examined for the presence of Clostridium perfringens. Of this total, 161 were raw, unprocessed beef, veal, lamb, pork, or chicken; 101 were processed meats and meat dishes. C. perfringens was isolated from 113 (43.1%) of these specimens. The highest percentage of contamination (82%) was found in veal cuts, and the lowest (4.7%) in sliced sandwich meats and spreads. Only 2 of the 113 isolates were shown to produce heat-resistant spores, which indicates a very low incidence (0.8%) of contamination. These findings indicate that outbreaks of C. perfringens food-borne disease in the Cincinnati area are caused principally by the contamination of the food with vegetative cells or spores of the organism after cooking. Studies of the effects of various holding temperatures on the growth of C. perfringens indicated that, in the range of 5 to 15 C, no multiplication would occur, but that viable cells would still be present at the end of a 5-day holding period. Extremely rapid growth occurred at temperatures around 45 C, and complete inhibition of growth was accomplished between 49 and 52 C.

    2013-06-01

    Full Text Available Heterocyclic amines (HA are the mutagenic/carcinogenic compounds which generate as a result of cooking of red meat, poultry meat and fish fillets at high temperatures. Up to 20 different HAs were detected and classified in the researches that conducted on these types of meats cooked at high temperatures. HAs are the products of Maillard reactions and the Strecker degredation of main precursors such as creatine/creatinine, aminoacid and the polysaccharides. Many physical and chemical factors effect the formation of HAs. Thus, it was reported by many researchers that utilizing coating and marination processes in addition to using natural and synthetic antioxidants and seasonings-plant extracts were effective on inhibiting/decreasing the formation of HAs. Additionally, boiling/steaming and microwave cooking methodologies were recommended instead of barbecuing, grilling or frying to inhibit/decrease the formation of HAs. The HAs formed in meat and meat products and the factors which have effects on the formation of HAs are presented in this review.

  13. Volatile compounds in meat and meat products

    Directory of Open Access Journals (Sweden)

    Monika KOSOWSKA

    Full Text Available Abstract Meaty flavor is composed of a few hundreds of volatile compounds, only minor part of which are responsible for the characteristic odor. It is developed as a result of multi-directional reactions proceeding between non-volatile precursors contained in raw meat under the influence of temperature. The volatile compounds are generated upon: Maillard reactions, lipid oxidation, interactions between Maillard reaction products and lipid oxidation products as well as upon thiamine degradation. The developed flavor is determined by many factors associated with: raw material (breed, sex, diet and age of animal, conditions and process of slaughter, duration and conditions of meat storage, type of muscle, additives applied and the course of the technological process. The objective of this review article is to draw attention to the issue of volatile compounds characteristic for meat products and factors that affect their synthesis.

    1977-01-01

    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.

    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.

    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.

    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.

    2002-01-01

    The article presents an overview of a research conducted in the Estonian Inst. of Economics and the Estonian Energy Research Inst. with the objectives to: analyse the dynamics of the main Estonian energy use indicators over the last 8-10 years with the background of general macroeconomics developments; compare these indicators with the respective energy indicators in the European Union Member States and Candidate Countries; evaluate Estonia's potential to catch up by the energy use efficiency (GDP energy intensity) of the average level of EU countries, modelling our possible development scenarios of GDP and TPES. The research results indicates several positive development tendencies (e.g. reduction of TPES and CO 2 emissions with the background of economic growth) in the Estonian energy sector, as well as convergence with the EU countries in terms of GDP energy intensity. Unfortunately, the model analysis results demonstrate that it takes a lot of time for Estonia to reach the current EU level - even under the most favourable GDP and TPES development conditions, 25-30 years. The primary reason is the very low level of our GDP per capita compared to the EU countries. (author)

    Full Text Available The article deals with the development in Russian-Estonian relations during the crises of 2007 and 2014, taking into consideration the balance between political and economic factors in the decision-making by Estonian government. A number of special aspects, trends and problems in trade and investment ties are detected. The aim of the study is to uncover key motivation behind the actions of both Russia and Estonia, to identify the drivers for economic and political development in the region, and to work out recommendations to adjust them. The questions put forward by the authors of this article could not be more topical at the time, when Russian economic situation is obviously getting worse and capital flight (to the neighboring EU Member States is likely to increase. The method of the study is comparative analysis of the impact on economic ties made by Russian-Estonian crisis of 2007 and the current international tension around Ukraine. The regional fossil fuel market and the possibilities of Gazprom involvement in its development are also analyzed. It is concluded that political motives are still important for Estonian decisionmaking, though they are balanced out by measures of business support (despite some of these measures being taken by the EU bodies. The role of political factor for the Russian side is increasing. It is acknowledged that there is a growing number of missed economic opportunities in the Russian Northwest.

    2011-01-01

    The concept of organisational culture (also referred to later as OC) is one of the approaches in modern organisational analysis exploring the values, attitudes and beliefs behind human behaviour in the workplace. OC as a social phenomenon is considered to be important for the sustainability of every organisation. In the service sector, OC may affect the nature and quality of the services provided. The aim of this paper is twofold: on the one hand, to highlight the patterns of OC in a hospital; and, on the other hand, to outline relationships between OC and patient satisfaction. The study was conducted in Tartu University Hospital, one of the most influential health care organisations in Estonia. This paper has original value by presenting an insight into organisational culture in the Estonian health care sector, and the findings of the study will expand knowledge of OC in the health care sector in general. The OC instrument applied in a quantitative cross-sectional study was earlier developed according to the Competing Values Framework (CVF). Data from 456 medical and non-medical professionals were analysed using non-parametric tests of descriptive statistics. A factor analysis was performed to assess the instrument's compatibility for analysing the OC pattern in the health care sector. The dominant culture type in all the groups investigated was the Internal Processes type, mainly followed by the Rational Goal type, while different cultural patterns were observed in professional groups. The factor analysis yielded a three-subscale solution. Clinics with high patient satisfaction did not score more than clinics with low patient satisfaction in terms of the Human Relations type. In future studies a random sample design and a multidisciplinary approach to OC research should be followed in order to further explore OC patterns in hospitals and their consequences for different aspects of hospital performance.

    As energy demand and prices continue to grow, oil shale might help mitigate the energy crisis—it can widely be found all over the world but so far has not been widely used. Estonia is unique in the world for producing a large majority of energy out of oil shale and has been set as an example in numerous papers covering oil shale deposits, technology etc. This paper is the first to analyse oil shale energy related workforce and provides scenario forecasts of the labour demand for the Estonian energy sector in 2010–2020. The contribution of the paper is twofold. First, the paper provides a valuable insight into oil shale energy related workforce, enabling to take into consideration the educational needs in countries where oil shale industry might be set up. Second, methodology-wise, the paper relates labour demand and supply to different scenarios of energy production capacities. The results illustrate problems related to aging of the workforce in energy production. If the existing trends continue in educational attainment in Estonia, there will be a serious shortage of high-skilled engineering and manufacturing specialists. Our method provides a simple yet reliable enough way to check for such problems early enough. - Highlights: ► This paper analyses oil shale energy related workforce and provides scenario forecasts. ► This is the first study to investigate the workforce related to oil shale energy production. ► The main workforce-related problem in the sector is ageing of the workforce. ► Workers immigrating to the sector during the Soviet times are at the retirement age. ► There will be a serious shortage of engineers for energy sector in the near future.

    This study aimed to determine Salmonella spp. prevalence in meat products, meat preparations and minced meat. Over a period of three years, a total of 300 samples were taken (100 RTE meat products, 100 meat preparations and 100 minced meat) and examined for the presence of Salmonella spp. Sampling was carried out at the warehouses of the food manufacturers. Salmonella spp. were not detected in RTE meat products, while 7% of semi-finished meat products (fresh sausages, grill meat formed and unformed) contained Salmonella, as did 18% of minced meats (minced pork II category, minced beef II category, mixed minced meat). The 25 Salmonella isolates obtained were examined for antibiotic resistance by the disk diffusion test, according to the NCCLS and CLSI guidelines. Isolates showed resistance to ampicillin and nalidixic acid (80%), tetracycline (72%), cefotaxime/clavulanic acid (48%), but not to gentamicin (8%) or trimethoprim/sulfamethoxazole (0%).

    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.

    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

    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.

    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.

    Full Text Available This article attempts to explain the relationships between journalists, politics and the state from the perspective of collective autonomy, that of the professional organization of journalists. The case of Estonian Journalists’ Union demonstrates the complexity and historical contingency of professional autonomy of journalism. The development of the Estonian journalists’ organization occurred as a sequence of transformations from the Estonian Journalists’ Association to the Estonian Journalists’ Union to the Soviet type journalists’ union, and lastly to an independent trade union. This sequence was disrupted by several fatal breakdowns that changed not only the character of the association, but also professional values, the whole occupational ideology and the conditions of the existence of journalism as a profession in Estonia.

    Full Text Available This article begins by examining points of intersection between two professional theatres, ”Estonia” and ”Vanemuine” (both established in 1906, their young directors – Karl Menning, Paul Pinna, Theodor Altermann, and Karl Jungholz, and the literary movement Young Estonia. Subsequently, we will consider Young Estonia’s theatrical ideals and the influence of these ideas on later Estonian theatrical life. Since not much information has survived regarding direct personal contacts between ”movers and shakers” in the theatre world and Young Estonians, the main focus here shall be on indirect creative connections and influences. One such context is education: like the Young Estonians, theatre activists of the younger generation aspired to place themselves on the larger map of European culture. Thus, their artistic beliefs and goals shall be examined in relation to those of Young Estonians’ quest for modern culture. Pinna, Altermann, Menning, Jungholz, and others went on study tours to Germany and France, where they were energized and inspired by innovative German and Russian theatres, by naturalistic staging, and by psychological realism, both in acting and in performance style. Among their models were A. Antoine’s Théâtre- Libre in Paris, K. Stanislavski’s Art Theatre in Moscow, O. Brahm’s Lessing-Theater, and M. Reinhardt’s Deutsches Theater in Berlin. These models were likewise known to the Young Estonians, but if theatre activists oriented themselves more fundamentally to German naturalist and realist dramatic art, Young Estonians were more taken with ”theatrical theatre” with its symbolist and impressionist influences. The Young Estonians attended performances at both theatres, ”Vanemuine” and ”Estonia”, and wrote numerous theatre reviews. Yet in the Young Estonia albums (yearbooks and in the magazine Young Estonia, theatre topics have a relatively modest representation. Young Estonians did not have direct

  8. The Meat City

    This article investigates the emergence of the Copenhagen slaughterhouse, called the Meat City, during the late nineteenth century. This slaughterhouse was a product of a number of heterogeneous components: industrialization and new infrastructures were important, but hygiene and the significance...... of Danish bacon exports also played a key role. In the Meat City, this created a distinction between rising production and consumption on the one hand, and the isolation and closure of the slaughtering facility on the other. This friction mirrored an ambivalent attitude towards meat in the urban space: one...... where consumers demanded more meat than ever before, while animals were being removed from the public eye. These contradictions, it is argued, illustrate and underline the change of the city towards a ‘post-domestic’ culture. The article employs a variety of sources, but primarily the Copenhagen...

    Meat spoilage during distribution can be considered as an ecological phenomenon that encompasses the changes of the available substrata (e.g., low molecular compounds), during the prevailing of a particular microbial association, the so-called specific spoilage organisms (SSO). In fact, spoilage of meat depends on an even smaller fraction of SSO, called ephemeral spoilage organisms (ESO). These ESO are the consequence of factors that dynamically persist or imposed during, e.g., processing, transportation and storage in the market. Meanwhile spoilage is a subjective judgment by the consumer, which may be influenced by cultural and economic considerations and background as well as by the sensory acuity of the individual and the intensity of the change. Indeed, when spoilage progresses, most consumers would agree that gross discoloration, strong off-odors, and the development of slime would constitute the main qualitative criteria for meat rejection. On the other hand, meat industry needs rapid analytical methods or tools for quantification of these indicators to determine the type of processing needed for their raw material and to predict remaining shelf life of their products. The need of an objective evaluation of meat spoilage is of great importance. The use of metabolomics as a potential tool for the evaluation of meat spoilage can be of great importance. The microbial association of meat should be monitored in parallel with the estimation of changes occurring in the production and/or assimilation of certain compounds would allow us to evaluate spoilage found or produced during the storage of meat under different temperatures as well as packaging conditions.

    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.

  12. Advancements in meat packaging.

    2017-10-01

    Packaging of meat provides the same or similar benefits for raw chilled and processed meats as other types of food packaging. Although air-permeable packaging is most prevalent for raw chilled red meat, vacuum and modified atmosphere packaging offer longer shelf life. The major advancements in meat packaging have been in the widely used plastic polymers while biobased materials and their integration into composite packaging are receiving much attention for functionality and sustainability. At this time, active and intelligent packaging are not widely used for antioxidant, antimicrobial, and other functions to stabilize and enhance meat properties although many options are being developed and investigated. The advances being made in nanotechnology will be incorporated into food packaging and presumably into meat packaging when appropriate and useful. Intelligent packaging using sensors for transmission of desired information and prompting of subsequent changes in packaging materials, environments or the products to maintain safety and quality are still in developmental stages.

  13. Chemistry of the Estonian oil-shale kukersite

    Energy Technology Data Exchange (ETDEWEB)

    Kogerman, P N

    1931-01-01

    Estonian oil shale is one of the oldest and richest oil shales in the world. The deposits occur in the Middle-Ordovician strata having a total thickness of 2.2 meters. The ultimate composition of the kerogen varied within the following limits: carbon 76.5 to 76.7 percent, hydrogen 9.1 to 9.2 percent, nitrogen 0.2 to 0.4 percent, sulfur 1.6 to 2.2 percent, chlorine 0.5 to 0.7 percent, and oxygen (by difference) 11.2 to 12.2 percent. The composition of kukersite kerogen corresponds nearly to the empirical formula (C/sub 8/H/sub 11/O)n. One of the most significant differences between kukersite, coal, and lignite is the amount of alkali-soluble substances present. Kukersite has almost no humic acids. Samples of kukersite were brominated and chlorinated. The halogenated shales showed a solubility in absolute alcohol of 26 percent compared to only 0.31 percent for untreated shale. Enriched shale (4.5 percent ash) did not react with chlorine as much as did raw shale. Apparently the mineral matter acted catalytically during chlorination. The amount of soluble extract obtained by solvent treatment of kukersite ranged from 0.22 percent with chloroform to 2.20 percent with tetrachloroethane. Heat was the most effective agent for the depolymerization of kukersite kerogen. The percentage loss of weight due to drying in air was much less than in the presence of carbon dioxide. The results indicated that on drying in air, the powdered shale loses water and a volatile substance, probably the oxides of carbon, up to 80/sup 0/C. Carbon dioxide was also found to be present in the gases eliminated at the temperature of initial decomposition. Pulverized shale, heated for 6 hours at 220/sup 0/C, lost 2.6 percent of its weight; its solubility in carbon disulfide was 2.11 percent. Kukersite kerogen was formed from compounds that were resistent to bacteriological decomposition, such as waxes and resins, plus decomposition products of proteins, cellulose, and putrefaction products of

    This paper presents the results of the distribution of trace elements in Estonian mires. Sixty four mires, representative of the different landscape units, were analyzed for the content of 16 trace elements (Cr, Mn, Ni, Cu, Zn, and Pb using AAS; Cd by GF-AAS; Hg by the cold vapour method; and V, Co, As, Sr, Mo, Th, and U by XRF) as well as other peat characteristics (peat type, degree of humification, pH and ash content). The results of the research show that concentrations of trace elements in peat are generally low: V 3.8 ± 0.6, Cr 3.1 ± 0.2, Mn 35.1 ± 2.7, Co 0.50 ± 0.05, Ni 3.7 ± 0.2, Cu 4.4 ± 0.3, Zn 10.0 ± 0.7, As 2.4 ± 0.3, Sr 21.9 ± 0.9, Mo 1.2 ± 0.2, Cd 0.12 ± 0.01, Hg 0.05 ± 0.01, Pb 3.3 ± 0.2, Th 0.47 ± 0.05, U 1.3 ± 0.2 μg g - 1 and S 0.25 ± 0.02%. Statistical analyses on these large database showed that Co has the highest positive correlations with many elements and ash content. As, Ni, Mo, ash content and pH are also significantly correlated. The lowest abundance of most trace elements was recorded in mires fed only by precipitation (ombrotrophic), and the highest in mires fed by groundwater and springs (minerotrophic), which are situated in the flood plains of river valleys. Concentrations usually differ between the superficial, middle and bottom peat layers, but the significance decreases depending on the type of mire in the following order: transitional mires - raised bogs - fens. Differences among mire types are highest for the superficial but not significant for the basal peat layers. The use of peat with high concentrations of trace elements in agriculture, horticulture, as fuel, for water purification etc., may pose a risk for humans: via the food chain, through inhalation, drinking water etc.

    The effect of reducing pork meat concentrations from 50% to 30% and replacing it with up to 20% pork head meat on chemical composition, cooking characteristics, physicochemical and textural properties, apparent viscosity, and sensory characteristics of frankfurters was determined. The highest moisture content in frankfurters was found in the control and T1 (frankfurter with 45% pork meat + 5% pork head). Protein and fat contents in frankfurters with pork head meat added were significantly (ppork head meat was increased from 0% to 20%, cooking loss, total expressible fluid separation, fat separation, and pH of frankfurters were increased, while the lightness, redness, yellowness, and apparent viscosity of frankfurters were decreased. Ash contents, cohesiveness, color, and tenderness of sensory characteristics of frankfurters added with different amounts of pork meat or pork head meat were not significantly (p>0.05) different from those of the control or there treatments. Frankfurters in T4 (frankfurter with 30% pork meat + 20% pork head) had the lowest (p0.05) from that in the control. Frankfurters with higher pork head meat concentrations had lower flavor, juiciness, and overall acceptability scores. Therefore, replacing pork meat with pork head meat in the formulation could successfully produce results similar to those of control frankfurters. The best results were obtained when 10% pork head meat was used to replace pork meat. PMID:27621683

    Graded levels of phytic acid (PA) were fed to day-old Japanese quail (Coturnix coturnix japonica) for 7 d to establish responses for evaluating effects of inositol tri-, tetra-, and pentaphosphates. Sodium phytate was added to supply 1.4, 2.8, 5.5, 8.4, 11.0, and 13.8 g PA/kg adequate casein-gelatin diet containing 20 mg Zn/kg. Eleven g phytic acid approximates that in diets containing defatted soy flour as the protein source. PA:Zn molar ratios were 7, 14, 27, 41, 54, and 68. The effects and graded response ranges (g PA/kg diet) were as follows: decreased body weight, 2.8-13.8; defective feathering, 1.4-5.5; decreased tibia Zn, 1.4-5.5; decreased tibia ash, 1.4-13.8; and decreased pancreas Zn, 1.4-5.5. The lowest level of PA produced marked decreases in tibia and pancreas Zn; thus the PA ranges can be extended to even lower levels. The effects of PA were reproducible between experiments and the mean values were reproducible except for tibia ash and liver Mn, which varied somewhat. There were no effects of PA on liver Zn and Mg, or on pancreas Fe and Mg; the effects on liver Fe and Cu, and tibia Fe and Mg were small and inconsistent. The responses to PA and the dose ranges provide a realistic basis for assessing the biological effects of other inositol phosphates that can be formed during food processing

    Full Text Available Abstract Background Endogenous peptides such as neuropeptides are involved in numerous biological processes in the fully developed brain but very little is known about their role in brain development. Japanese quail is a commonly used bird model for studying sexual dimorphic brain development, especially adult male copulatory behavior in relation to manipulations of the embryonic endocrine system. This study uses a label-free liquid chromatography mass spectrometry approach to analyze the influence of age (embryonic days 12 vs 17, sex and embryonic day 3 ethinylestradiol exposure on the expression of multiple endogenous peptides in the developing diencephalon. Results We identified a total of 65 peptides whereof 38 were sufficiently present in all groups for statistical analysis. Age was the most defining variable in the data and sex had the least impact. Most identified peptides were more highly expressed in embryonic day 17. The top candidates for EE2 exposure and sex effects were neuropeptide K (downregulated by EE2 in males and females, gastrin-releasing peptide (more highly expressed in control and EE2 exposed males and gonadotropin-inhibiting hormone related protein 2 (more highly expressed in control males and displaying interaction effects between age and sex. We also report a new potential secretogranin-2 derived neuropeptide and previously unknown phosphorylations in the C-terminal flanking protachykinin 1 neuropeptide. Conclusions This study is the first larger study on endogenous peptides in the developing brain and implies a previously unknown role for a number of neuropeptides in middle to late avian embryogenesis. It demonstrates the power of label-free liquid chromatography mass spectrometry to analyze the expression of multiple endogenous peptides and the potential to detect new putative peptide candidates in a developmental model.

    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).

    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.

    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 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.

    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.

    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.

    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 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.

  11. Meat and meat products as a source of bioactive peptides

    Full Text Available Meat is a high protein content food, with great nutritional and biological value. Meat protein hydrolysis begins with the muscle to meat conversion, during meat ageing. After slaughter, endogen enzymes are responsible of meat softening since myofibrillar anchorage proteins are degraded. Protein hydrolysis continues during food preparation. When meat reaches the stomach, pepsin is the first enzyme to interact. As the food travel trough out gastrointestinal tract, pancreatic enzymes degraded the remained protein and the peptidases made the final proteolysis process. The small proteins or peptides are the absorbed to the circulatory system and distributed to the rest of the body. Bioactive peptides activity of meat and meat products is anti-hypertensive mainly, where histidine, carnosine and anserine are the main peptides identified. Another peptide with anti-oxidant activity is glutathione. The content depends on animal species.

    Full Text Available The meat production and meat processing industry are the most important parts of the agribusiness in the Czech Republic. The problem of the industry is its low competitiveness towards foreign producers and processors which results in negative balance of foreign trade. The aim of the article is to evaluate long-term development of value and structure of Czech foreign trade flows of meat and meat products. The analysis covers the period of 2001–2014. The problems of the negative trade balance are revealed through description of the trade flows of meat and meat products, the RCA index and relations between import and export prices. The analysis points out the problems of low competitiveness of the intermediate and finalized meat. Alternatively, Czech Republic has comparative advantage in live animals, sausages and homogenized meat products.

    In the recent years, Muslims have become increasingly concerned about the meat they eat. Proper product description is very crucial for consumers to make informed choices and to ensure fair trade, particularly in the ever growing halal food market. Globally, Muslim consumers are concerned about a number of issues concerning meat and meat products such as pork substitution, undeclared blood plasma, use of prohibited ingredients, pork intestine casings and non-halal methods of slaughter. Analytical techniques which are appropriate and specific have been developed to deal with particular issues. The most suitable technique for any particular sample is often determined by the nature of the sample itself. This paper sets out to identify what makes meat halal, highlight the halal authenticity issues that occur in meat and meat products and provide an overview of the possible analytical methods for halal authentication of meat and meat products.

    Full Text Available The present study aimed at evaluating the effect of the dietary inclusion of organic trace minerals selenium and zinc on the performance and internal and external egg quality of Japanese quails submitted to heat stress. 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.

    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 This paper focuses on the meanings assigned to Tatar language among the Tatar diaspora in Estonia. According to interviews with Estonian Tatars as well as descriptions of field material from Tatarstan, language is an important aspect of Tatar ethnic identity. This paper will track common discourses about the Tatar language and the way it is connected to Tatar ethnic identity. Issues concerning Tatar language are used to demonstrate various ways of enacting Tatarness in Estonia. It is shown that Estonian Tatars worry about the vitality and purity of Tatar language, but for some, marginalization of dialects is also an issue. People categorized with the same identity labels by self and others can experience and enact their Tatarness in a variety of different ways.

    2004-04-01

    This case study of the Estonian Genome Project (EGP) analyses the Estonian policy decision to construct a national human gene bank. Drawing upon qualitative data from newspaper articles and public policy documents, it focuses on how proponents use discourse to link the EGP to the broader political goal of securing Estonia's position within the Western/European scientific and cultural space. This dominant narrative is then situated within the analytical notion of the "brand state", which raises potentially negative political consequences for this type of market-driven genomic research. Considered against the increasing number of countries engaging in gene bank and/or gene database projects, this analysis of Estonia elucidates issues that cross national boundaries, while also illuminating factors specific to this small, post-Soviet state as it enters the global biocybernetic economy.

    2013-01-01

    Consumers rely heavily on fresh meat color as an indicator of wholesomeness at the point of sale, whereas cooked color is exploited as an indicator of doneness at the point of consumption. Deviations from the bright cherry-red color of fresh meat lead to product rejection and revenue loss. Myoglobin is the sarcoplasmic heme protein primarily responsible for the meat color, and the chemistry of myoglobin is species specific. The mechanistic interactions between myoglobin and multiple extrinsic and intrinsic factors govern the color of raw as well as cooked meats. The objective of this review is to provide an overview of the current research in meat color and how the findings are applied in the meat industry. Characterizing the fundamental basis of myoglobin's interactions with biomolecules in postmortem skeletal muscles is necessary to interpret the chemistry of meat color phenomena and to engineer innovative processing strategies to minimize meat discoloration-induced revenue loss to the agricultural economy.

  8. Is Estonian oil shale beneficial in the future?

    Reinsalu, Enno

    1998-01-01

    Oil shale mining production reached its maximum level of 31.35·10 6 tonnes per year in 1980. After the eighties there was a steady decline in mining. The first scientific prognoses of the inescapable decrease in oil shale mining were published in 1988. According to this, the Estonian oil shale industry would vanish in the third decade of the next century. From the beginning of the nineties, the consumption and export of electricity have dropped in Estonia. The minimum level of oil shale mining was 13.5·10 6 tonnes per year. This occurred in 1994/1995. Some increase in consumption of electric power and oil shale began at the end of 1995. Oil shale processing began to increase gradually in 1993. Oil shale is the most important fuel in Estonia today. In 1997, oil shale provided 76% of Estonia's primary energy supply and accounted for 57% of its economic value. Oil shale is the cheapest fuel in Estonia. Nowadays, oil shale provides an essential part of the fuel supply in Estonia because it is considerably cheaper than other fuels. Oil shale costs EEK 12.16 per G J. At the same time, coal costs EEK 23.41 per G J and peat costs EEK 14.80 per G J (year 1997). There are three important customers of oil shale: the electric power company Eesti Energia, the oil processing company Kiviter and the factory Kunda Nordic Cement. In 1995, the power company utilised 81% of the oil shale mass and 77% of its heating value. The state energy policy inhibits increases in the oil shale price even though the mining infrastructure is decaying. Government price policies subside oil shale processing. The energy of oil shale processing is 1.9 times cheaper than the heating value of raw oil shale for power stations. It could be considered as a state subsidisation of oil and cement export at the expense of electricity. The subsidy assigned to oil processing was of EEK 124·10 6 and to the cement industry of EEK 8.4·10 6 in year 1997 (based on heating value). State regulation of prices and

    We present data from an observational cohort study on human immunodeficiency virus (HIV) prevention and control measures in prisons in Estonia to assess the potential for HIV transmission in this setting. HIV testing and retesting data from the Estonian prison health department were used to estimate HIV prevalence and incidence in prison. Since 2002, voluntary HIV counselling and testing has routinely been offered to all prisoners and has been part of the new prisoners health check. At the end of 2012, there were 3,289 prisoners in Estonia, including 170 women: 28.5% were drug users and 15.6% were infected with HIV. Of the HIV-positive inmates, 8.3% were newly diagnosed on prison entry. In 2012, 4,387 HIV tests (including retests) were performed in Estonian prisons. Among 1,756 initially HIV-negative prisoners who were in prison for more than one year and therefore tested for HIV twice within 12 months (at entry and annual testing), one new HIV infection was detected, an incidence of 0.067 per 100 person-years (95% confidence interval (CI): 0.025–5.572). This analysis indicates low risk of HIV transmission in Estonian prisons. Implementation of HIV management interventions could impact positively on the health of prisoners and the communities to which they return.

  11. Estonian folk traditional experiences on natural anticancer remedies: from past to the future.

    Despite diagnostic and therapeutic advancements, the burden of cancer is still increasing worldwide. Toxicity of current chemotherapeutics to normal cells and their resistance to tumor cells highlights the urgent need for new drugs with minimal adverse side effects. The use of natural anticancer agents has entered into the area of cancer research and increased efforts are being made to isolate bioactive products from medicinal plants. To lead the search for plants with potential cytotoxic activity, ethnopharmacological knowledge can give a great contribution. Therefore, the attention of this review is devoted to the natural remedies traditionally used for the cancer treatment by Estonian people over a period of almost 150 years. Two massive databases, the first one stored in the Estonian Folklore Archives and the second one in the electronic database HERBA ( http://herba.folklore.ee/ ), containing altogether more than 30 000 ethnomedicinal texts were systematically reviewed to compile data about the Estonian folk traditional experiences on natural anticancer remedies. As a result, 44 different plants with potential anticancer properties were elicited, 5 of which [Angelica sylvestris L. (Apiaceae), Anthemis tinctoria L. (Asteraceae), Pinus sylvestris L. (Pinaceae), Sorbus aucuparia L. (Rosaceae), and Prunus padus L. (Rosaceae)] have not been previously described with respect to their tumoricidal activities in the scientific literature, suggesting thus the potential herbal materials for further investigations of natural anticancer compounds.

    To compare smoking behaviour, attitudes and opinions towards smoking and smoking cessation among Estonian and Finnish physicians. A cross-sectional postal survey using a self-administered questionnaire was carried out among 2,480 Estonian and 2,075 Finnish physicians. Daily smoking prevalence was higher among Estonian physicians than among their Finnish counterparts in both male (18.6% and 6.7%) and female (6.6% and 3.6%). Compared to Estonia, physicians in Finland more often agreed that smoking is very harmful to their health, that trying to convince people to stop smoking is their responsibility and that smoking prevention should be part of the normal and special training of health professionals. In both countries, non-smoking physicians held more unfavourable attitudes towards smoking than those who were smoking. Physicians' own smoking patterns and quitting behaviour are important because physicians serve as models for their patients and play a key role in the reinforcement of smoke-free health facilities. These results remain a challenge to medical educators, especially in Estonia. Estonia needs to improve medical education in terms of motivating physicians to ask about the smoking patterns of their patients and of training medical students and resident physicians to counsel their patients to stop smoking.

    The report describes the development and summarizes the results of the project Cancer incidence and thyroid disease among Estonian Chernobyl clean-up workers. One of the goals of the report is to give research protocols and questionnaires for researchers involved in other studies. Eight previously published articles are also included summarizing the results. The development of the collaboration work of the project is described in the introduction of the report. Epidemiological methods are described in an article complemented by the protocol and English version of the questionnaire administered to all cleanup workers, as well as the data collection form of the thyroid study. The results from biological biodosimetry using both glycophorin A and FISH methods have shown that the radiation doses received by the Chernobyl cleanup workers were relatively low. Thyroid nodularity was not associated with any radiation exposure characteristic in the thyroid screening study. Estonian Chernobyl cleanup workers were followed up for cancer incidence through the Estonian Cancer Registry. No cases of leukemia or thyroid cancer were observed by the end of 1993. It is too early to observe possible effect on other types of cancer. However, mortality from suicides was increased compared with general population. Further follow-up and the extension to other Baltic countries in the future will undoubtedly strengthen the study. There are also plans for future projects covering areas from psychosocial factors to radiation biology

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

    This study reports on current meat consumption in the UK and the factors that are percieved by the subjects to be influential in their choice of diet. A random sample of individuals from the population (n-1018) were questioned on their consumption and attitudes towards meat by a postal survey. The study revealed that 28·3% of the population considered themselves to be reducing meat consumption; attitudes found to be determinant in changes in the consumption of meat were healthiness, taste and concerns over additives. Hypothetical future events were found to affect people's estimated meat-eating. Knowledge of meat-related information was investigated with specific reference to the respondents' trust in the various sources used; food package labels were found to be an influential source of meat-related information.

    The development in sequencing methods has made it possible to perform whole genome de novo sequencing of species without large commercial interests. Within the EU-financed QUANTOMICS project (KBBE-2A-222664), we have performed de novo sequencing of quail (Coturnix coturnix) and grey partridge...... (Perdix perdix) on a Genome Analyzer GAII (Illumina) using paired-end sequencing. The amount of generated sequences amounts to 8 to 9 Gb for each species. 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...

    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.

    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.

    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 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.

    The aim of this research is to determine the nutrient digestibility of vegetables waste flour on of male quail. Four hundred male quails were divided into four groups with five replications. The experiment is Completely Randomized Design and the data were analyzed by analyses of variants. The experimental diets were P0 = basal diet, P1 = 97% basal diet + 3% vegetables waste flour, P2 = 94% basal diet + 6% vegetables waste flour, and P3 = 91% basal diet + 9% vegetables waste flour. The observed variables were the digestibility of dry matter, crude protein and extract ether. Result showed that of the addition of vegetable waste flour in the diet had no effect on crude protein digestibility (P>0.05), however shown significant effect on dry matter (P digestibility.

    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 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.

    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

    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.

  16. Dopamine modulates male sexual behavior in Japanese quail in part via actions on noradrenergic receptors.

    Science.gov (United States)

    Cornil, Charlotte A; Dejace, Christel; Ball, Gregory F; Balthazart, Jacques

    2005-08-30

    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.

    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

    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.

    1987-01-01

    Effects of ambient temperature on the acute oral toxicity of parathion were investigated in Japanese quail (Coturnix japonica) maintained at thermoneutral temperature (26.degree. C) or exposed to elevated (37.degree. C) or reduced (4.degree. C) temperatures commonly encountered by free-ranging wild birds. 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.

  20. Effect of Increasing Yolk Testosterone Levels on Early Behaviour in Japanese Quail Hatchlings

    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.

    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.

    In this study, 400 unsexed Japanese quail chicks (1 day old) were used. The quail chicks were randomly assigned into four groups of 100 birds in each. The first group was served as control. The other experimental groups were fed on a basal diet supplemented with 0.5% yeast/kg diet (G2), 0.5% yeast/kg diet ± 200 mg fumonicin-B1/kg diet (G3) and 200 mg fumonicin-B1/kg diet (G4). The results showed significant increases in mortality rate, GPT (ALT), GOT (AST), cholesterol, uric acid, creatinine and alpha-fetoprotein (AFP) and decreases in body weight, hatchability, fertility and hatching weight, serum total proteins, globulin and glutathione peroxidase (GPx) activity in group of quails received fumonisin (G4) in comparison with the control group (G1) and all treatments. Yeast led to partial improvement in the parameters in group two (G2). Also, yeast suppressed the toxic effect of fumonisin B-1 (G3)

    In this study, 400 unsexed Japanese quail chicks (1 day old) were used. The quail chicks were randomly assigned into four groups of 100 birds in each. The first group was served as control. The other experimental groups were fed on a basal diet supplemented with 0.5% yeast/kg diet (G2), 0.5% yeast/kg diet {+-} 200 mg fumonicin-B1/kg diet (G3) and 200 mg fumonicin-B1/kg diet (G4). The results showed significant increases in mortality rate, GPT (ALT), GOT (AST), cholesterol, uric acid, creatinine and alpha-fetoprotein (AFP) and decreases in body weight, hatchability, fertility and hatching weight, serum total proteins, globulin and glutathione peroxidase (GPx) activity in group of quails received fumonisin (G4) in comparison with the control group (G1) and all treatments. Yeast led to partial improvement in the parameters in group two (G2). Also, yeast suppressed the toxic effect of fumonisin B-1 (G3)

    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.

    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 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

    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.

    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 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.

    The effects of pre-slaughter adrenalization and of treatment with additives of semifinished poultry products were studied with a view to improving the storage quality of irradiated poultry. It was found that pre-slaughter adrenalization, pre-irradiation treatment with phosphates and, particularly, a combination of these two methods considerably delayed the formation of carbonyl compounds, the delay being somewhat greater in white meat.

    In ''A Re-Evaluation of the Products of Gamma Irradiation of Beef Ferrimyoglobin'', J. Food Sci. 46:1814 (1981), authors Whitburn, Hoffman and Taub state that color pigment myoglobin (Mb) undergoes chemical changes during irradiation that cause color changes in meat. They also state that they are in disagreement with Giddings and Markakis, J. Food Sci. 47:361 (1972) in regard to generation of MbO 2 in deaerated solutions, claiming their analysis demonstrates only Mb and Mb(IV) production. Giddings, in a letter, suggests that Whitburn, et al may have used differing systems and approaches which critically changed the radiation chemistry. He also states that radiation sterilization of aerobically packaged meats affects color only slightly. Whitburn, in a reply, shares Dr. Giddings concern for caution in interpretation of results for this system. The compositional changes are dependent on identity of free radicals, dose, O 2 and the time of analysis after irradiation. The quantification of these parameters in pure systems, sarcoplasma extracts and in meat samples should lead to a better understanding of color change mechanisms and how to minimize them

  12. THE IMPORTANCE OF BACTERIOCINS IN MEAT AND MEAT PRODUCTS

    Full Text Available There is an increasing consumer demand for food products which are free of chemical additives, reduced in salt and processed as little as possible. These minimally processed foods require special application to assure their microbiological safety. The use of microorganisms and enzymes for food preservatives is called biopreservation. The most important group of microorganisms with antimicrobial effect used in the production of foods is the lactic acid bacteria. In meats although lactic acid bacteria constitue apart of the initial microflora, they become dominant during the processing of meats. In this research bacteriocins of lactic acid bacteria and their usage in meat and meat products for biopreservation are discussed.

    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.

    Soil organic carbon (SOC) determines ecosystem functions, influencing soil fertility, soil physical, chemical and biological properties and crop productivity. Therefore the spatial pattern of SOC stocks and its appropriate management is important at various scales. Due to climate change and the contribution of carbon store in the soils, the national estimates of soil carbon stocks should be determined. Estonian soils have been well studied and mapped at a scale 1:10,000. Previous studies have estimated SOC stocks based on combinations of large groups of Estonian soils and the mean values of the soil profile database, but were not embedded into the geo-referenced databases. These studies have estimated SOC stocks of Estonian arable soils 122.3 Tg. Despite of available soil maps and databases, this information is still very poorly used for spatial soil modelling. The aim of current study is to assess and model spatial pattern of SOC stocks of arable soils on a pilot area Tartu County (area 3089 sq km). Estonian digital soil map and soil monitoring databases are providing a good opportunity to assess SOC stocks at various scales. The qualitative nature of the initial data from a soil map prohibits any straightforward use in modelling. Thus we have used several databases to construct models and linkages between soil properties that can be integrated into soil map. First step was to reorganize the soil map database (44,046 mapping units) so it can be used as an input to modelling. Arable areas were distinguished by a field layer of Agricultural Registers and Information Board, which provides precise information of current land use as it is the basis of paying CAP subsidies. The estimates of SOC content were found by using the arable land evaluation database of Tartu from the Estonian Land Board (comprising 950 sq km and 31,226 fields), where each soil type was assessed separately and average SOC content grouped by texture was derived. SOC content of epipedon varies in

    The maturation of the US beef and pork markets and increasing consumer demands for convenience, safety, and nutrition suggests that the beef and pork industries must focus on product development and promotion. New marketing arrangements are developing that help coordinate production with consumer demands. The relative high levels of incomes in the United States are likely to increase the demands for branded products rather than increase total per capita consumption. Foreign markets represent the greatest opportunity for increased demand for commodity beef and pork products. Increasing incomes in developing countries will likely allow consumers to increase consumption of animal-source proteins. Real prices of beef and pork have declined substantially because of sagging domestic demand and increasing farm-level production technologies. Increasing US beef and pork exports have obviated some of the price declines. Pork attained a net export position from a quantity perspective in 1995. The United States continues to be a net importer of beef on a quantity basis but is close to becoming a net exporter in terms of value. By-products continue to play a critical role in determining the red meat trade balance and producer prices. The United States, however, must continue to become cost, price, and quality competitive with other suppliers and must secure additional market access if it is to sustain recent trade trends. Several trade tensions remain in the red meat industry. For example, mandated COOL will undoubtedly have domestic and international effects on the beef and pork sectors. Domestically, uncertainty regarding consumer demand responses or quality perceptions regarding product origin, as well as added processor-retailer costs will be nontrivial. How these factors balance out in terms of benefits versus costs to the industry is uncertain. From an international perspective, some beef and pork export suppliers to the United States could view required labeling as a

    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

    Smoking surveys among physicians have proved useful in highlighting the importance of physicians as healthy life style exemplars and role models in tobacco control and smoking cessation. The aim of this study was to give an overview of smoking behaviour among Estonian physicians from 1982 to 2014. Three cross-sectional postal surveys using a self-administered questionnaire were carried out among all practising physicians in Estonia. The number of physicians participating in this study was 3786 in 1982, 2735 in 2002, and 2902 in 2014. Data analysis involved calculating the age-standardized prevalences of smoking, prevalences of smoking by age group and mean age of smoking initiation. A non-parametric test for trend was used to assess significant changes in smoking over time. Age-standardized prevalence of current smoking among men was 39.7% in 1982, 20.9% in 2002, and 14.3% in 2014 and among women 12.2%, 8.0%, and 5.2%, respectively (p smoking among men and women was in age groups under 35 (from 55.2% to 16.7% and from 16.7% to 2.8%, respectively) and 35-44 (from 47.1% to 8.3% and from 19.5% to 5.1%, respectively) (p smoking initiation decreased from 20.4 to 19.3 among men and from 24.5 to 20.4 among women over the study period. In 1982-2014, smoking prevalence among Estonian physicians declined substantially. This may influence the willingness of society to recognize the health consequences of smoking which could give a support to the decline of the smoking epidemic in the country. Differences between smoking among male and female physicians persisted over the study period, but mean age of smoking initiation decreased. A further decline in smoking among Estonian physicians should be encouraged by special efforts targeted at physicians.

    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.

    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.)

    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.

    Full Text Available The article investigates lexical collocations encountered in English as a Foreign Language (EFL instruction in Estonian upper secondary schools. This is achieved through a statistical analysis of collocations featuring in three coursebooks where the collocations found are analysed in terms of their type, frequency and usefulness index by studying them through an online language corpus (Collins Wordbanks Online. The coursebooks are systematically compared and contrasted relying upon the data gathered. The results of the study reveal that the frequency and range of lexical collocations in a language corpus have not been regarded as an essential criterion for their selection and practice by any of the coursebook authors under discussion.

    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).

    Full Text Available Meat consumption during the first year of life is especially important to provide necessary iron requirements. The aim of the study was to assess meat and meat product consumption of Latvian infants during their first year of life, in relation to different factors. Data were collected by interview method using two types of questionnaires: food frequency questionnaires and food diary. The study included a representative sample of infants and toddlers from all regions of Latvia with a target sample of 560 participants. The study included 266 infants: 127 girls, 139 boys, aged from 0 to 12 month. Data were summarised using the Excel software and analysed using the SPSS software. For data analysis two age groups were created: 0–5.9 months and 6–12 months. Consumption was analysed by two parameters: frequency and amount per feeding. Meat products were defined as offal products, sausages, and meat in baby food. Meat was mainly consumed after 6 months of age and by 73% of infants (n = 107. Meat from baby food was consumed only after 6 months and by 23% (n = 34. Sausages and offal products were consumed after 6 months of age. Sausages were consumed by 18% (n = 28 and offal products by 11% (n = 16 of infants. Meat consumption for the majority of infants was introduced after 6 months and was in accordance with recommendations.

    In the Republic of Croatia, game meat is consumed far less than meat of domestic animals. Yearly game meat consumption amounts to only 0.55 kg per household member. Consumers prefer meat of domestic animals, because it is cheaper, not paying attention to specific nutritive advantages of game meat. A research on the game meat market and consumers’ preferences was carried out on 101 examinees, chosen among inhabitants of Slavonia and Baranja. The majority of questioned inhabitants did consume g...

    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.

    Full Text Available The article concentrates on Estonian novels depicting Soviet prison camps in the 1940s and 1950s. The goal is to map themes, motifs and characteristics in such novels, concentrating on various taboos and rules in the prison camp environment. For a long time the Soviet prison camp theme was not publicly discussed in Estonia due to political reasons. Texts dealing with prison camps could appear in print only outside the Soviet Union; the way Estonians saw these historical events and hellish experiences were depicted mostly in exile novels. Most notable are the novels by Arved Viirlaid (b. 1922, e.g., Kes tappis Eerik Hormi? (Who Killed Eerik Horm? (1974, Surnud ei loe (The Dead do not Read (1975, Vaim ja ahelad (Mind and Chains (1961. Estonian prison camp novels can be seen as “the literature of testimony”, to use the term by Leona Toker. Dramatic historical events are written down to record the events and to show the inhumane nature of Soviet society. These records of the dramatic past follow certain patterns and create certain self- and hetero-images. A prison camp is a closed territory within a closed territory; prison camps can be seen as small models of Soviet society. Prison camp novels give a detailed view of the environment of the prison camp, its inhabitants and activities. Two central aspects are labour and food; the life of the prisoner whirls around these. The most important thing is to survive, which often leads to moral decline, e.g., stealing, cheating. However, there are lines Estonians do not cross, e.g., cannibalism or homosexual relationships with superiors. Estonians are always depicted as political prisoners (not common criminals and heterosexuals, while Russians are portrayed mainly as criminals and often also as homosexuals. Another important component of the image of the Estonians is their enterprising spirit and ability to manage even under very difficult conditions. Therefore, several oppositions can be identified, e

    Cultured meat is a promising product that is derived through biotechnology that partially circumvents animal physiology, thereby being potentially more sustainable, environmentally friendly and animal friendly than traditional livestock meat. Such a novel technology that can impact many consumers evokes ethical, philosophical and religious discussions. For the Islamic community, the crucial question is whether cultured meat is halal, meaning compliant with Islamic laws. Since the culturing of meat is a new discovery, invention and innovation by scientists that has never been discussed by classical jurists (fuqaha'), an ijtihad by contemporary jurists must look for and provide answers for every technology introduced, whether it comply the requirements of Islamic law or not. So, this article will discuss an Islamic perspective on cultured meat based on the original scripture in the Qur'an and interpretations by authoritative Islamic jurists. The halal status of cultured meat can be resolve through identifying the source cell and culture medium used in culturing the meat. The halal cultured meat can be obtained if the stem cell is extracted from a (Halal) slaughtered animal, and no blood or serum is used in the process. The impact of this innovation will give positive results in the environmental and sustain the livestock industry.

    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 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.

    To study the long-term mental health consequences of the 1986 Chernobyl nuclear accident among cleanup workers from Estonia. In 2010, 614 Estonian Chernobyl cleanup workers and 706 geographically and age-matched population-based controls completed a mail survey that included self-rated health, the Posttraumatic Stress Disorder Checklist (PCL), alcohol symptoms (AUDIT), and scales measuring depressive, anxiety, agoraphobia, fatigue, insomnia, and somatization symptoms. Respondents were dichotomized into high (top quartile) and low symptom groups on each measure. Logistic regression analysis detected significant differences between cleanup workers and controls on all measures even after adjustment for ethnicity, education, marital status, and employment status. The strongest difference was found for somatization, with cleanup workers being three times more likely than controls to score in the top quartile (OR = 3.28, 95% CI 2.39-4.52), whereas for alcohol problems the difference was half as large (OR = 1.52, 95% CI 1.16-1.99). Among cleanup workers, arrival at Chernobyl in 1986 (vs. later) was associated with sleep problems, somatization, and symptoms of agoraphobia. The toll of cleanup work was evident 24 years after the Chernobyl accident among Estonian cleanup workers indicating the need for focused mental health interventions.

    One purpose of this project was the establishment of a radon monitoring programme inside the state environmental monitoring programme. Another purpose was to investigate regions, expected to have high radon levels indoors. A new method for the long-term measurement of indoor radon was established and the staff for these measurements was trained. The results of the measurement can be used by Estonian decision-makers to work out rules and standards. There is no legislative act in the field of radiation in Estonian at this time. To summarize the results of the measurements we can say that indoor radon concentrations vary by region. The radon investigations must be continued to identify the risk areas and types of housing construction. The results of the state radon monitoring are provided to the municipalities, who advice the owners of planned new houses to select the right construction for the house. A new project will follow with an investigation of radon in randomly selected dwellings, training and equipment for radon measurement in soil, and general advice with regard to radon, as well as assistance in preparing information about radon. 7 refs, 5 figs

    2012-01-01

    The organic meat industry in the United States has grown substantially in the past decade in response to consumer demand for nonconventionally produced products. Consumers are often not aware that the United States Department of Agriculture (USDA) organic standards are based only on the methods used for production and processing of the product and not on the product's safety. Food safety hazards associated with organic meats remain unclear because of the limited research conducted to determine the safety of organic meat from farm-to-fork. The objective of this review is to provide an overview of the published results on the microbiological safety of organic meats. In addition, antimicrobial resistance of microbes in organic food animal production is addressed. Determining the food safety risks associated with organic meat production requires systematic longitudinal studies that quantify the risks of microbial and nonmicrobial hazards from farm-to-fork.

    Iodine deficiency in Macedonia still persists in a mild form. In 1999 the iodination of salt rose to 20 m gr iodine in Kg salt. The consumption of salt diminished after the last war from 20-30 gr salt per day to 10-20 gr salt daily. This shows that the problem of the elimination of iodine deficiency is being vigorously tackled. Since 1956 the iodine in salt in Macedonia rose to 10 m gr KI/Kg salt. The content of iodine in the Macedonian diet seems to be important. The amount of iodine in milk, eggs and bread is low as found by the investigation of MANU. The content of iodine in meat is low, compared to British meat is 10 times lower. The average iodine content in Macedonian meat is 95.15 micro gr per Kg, whereas in British meat it is 850-1510 micro gr iodine per k gr meat. (Original)

    2002-11-01

    This paper discusses the management of meat tenderness using a carcass grading scheme which utilizes the concept of total quality management of those factors which impact on beef palatability. The scheme called Meat Standards Australia (MSA) has identified the Critical Control Points (CCPs) from the production, pre-slaughter, processing and value adding sectors of the beef supply chain and quantified their relative importance using large-scale consumer testing. These CCPs have been used to manage beef palatability in two ways. Firstly, CCPs from the pre-slaughter and processing sectors have been used as mandatory criteria for carcasses to be graded. Secondly, other CCPs from the production and processing sectors have been incorporated into a model to predict palatability for individual muscles. The evidence for the importance of CCPs from the production (breed, growth path and HGP implants), pre-slaughter and processing (pH/temperature window, alternative carcass suspension, marbling and ageing) sectors are reviewed and the accuracy of the model to predict palatability for specific muscle×cooking techniques is presented.

    Full Text Available This article aims to give an overview of literary instruction in schools of the russification era at the beginning of the 20th century in Estonia; this was likewise the curriculum of literary study offered to the generation of educated youth which included the Young Estonians. Based on official documents, archival materials, and memoirs, and through analyses of anthologies, literary histories, and teaching methods in use at the time, we attempt to reconstruct the outlines of literary reading and requirements for students in various types of schools. When, as a result of school reform, Russian became the language of instruction; lessons in Russian became central in the curriculum, alongside the word of God; selections from Russian literature were read in the original language. In the lower grades, teaching was by the so-called ”natural method”, intended to guarantee swift achievement of fluency in ”living Russian language”; this was later replaced by systematic textual analysis, which distinguished between belles lettres and other types of texts. However, the study of literature was always subordinated to the goals of language instruction. In institutions of secondary education, study of Russian literature was separate from language instruction. Indeed, Russian literature was the only literature systematically studied in high schools (though one must keep in mind that not all schools completely followed the official program. Private schools were especially noticeable for their greater freedom, though all of them had to take general curriculum directives into account. Reading of literary texts connected with other languages thus had to remain almost purely illustrative. In view of the above, in the upper grades of elementary school and high school, students obtained a thorough introduction to the Russian classics. According to the official school curriculum, Russian literary history ended with Nikolai Gogol. Attempts were made to ignore

    Full Text Available This paper analyses representations of the ‘core Soviet era’ (1945-1985 in Estonian post-Soviet history textbooks (1989-2016. Attitudes towards the Soviet system have been a rich resource for identity building, and hence a powerful political tool across the whole of the post-Soviet block. Based on an analysis of sections about the Soviet era in Estonia in 21 textbooks, the paper takes a look at how textbooks reflect broader processes of social meaning making, identity building and othering after a profound social and political turn. In 1989 and during the early 1990s, perspectives and narratives in Estonian history textbooks were closely related to social memory and national politics, enacting a specific social representation of the Soviet era that dominated the Estonian-speaking public space during the 1990s. The Soviet era, Russia and local Russians became the main Others for Estonia and Estonians. Over time, public discourse has diversified. The national curriculum and textbooks, however, still maintain the canon that formed in 1990s and thus reflect earlier sentiments. Apart from the increasing salience of Soviet-era daily life in more recent textbooks, the thematic choices and emphases have changed little since the 1990s. Therefore, even if the style of writing has ‘cooled down’, issues of identity preservation, resistance and accommodation, together with a saliently negative representation of wrongdoings by the Soviet system, still prevail. On the one hand, this testifies to the resilience of an established tradition in the textbook genre in general. On the other hand, it reflects the dominance of an ethnocentric tradition in Estonian history textbook writing. The paper discusses the implications of these findings for interethnic relations in Estonia.

    The radiation treatments that have received most attention with respect to red meats are radappertization, i.e. radiation sterilization (25-70 kGy), to enable the long term storage of meat without refrigeration, and radurization (0.5-10 kGy) in which a sufficient proportion of spoilage organisms are inactivated to enable the storage life of chilled meat to be extended. Shelf-stable radappertized meats cannot be produced in the fresh-like condition; they need to be heated to about 70 deg. C to inactivate endogenous enzymes that would otherwise cause flavour and texture defects. The products should be vacuum sealed in oxgyen-impermeable packages and irradiated in the frozen state, otherwise pronounced off-flavours and off-odours are formed. The radiation dose required to give a useful degree of microbial inactivation and permit an increase of storage life depends upon treatment and storage conditions. The dose required is likely to be in the range 0.25 to 1.0 kGy if aerobic conditions apply, and 1 to 4 kGy if anaerobic conditions apply. An acceleration in the rate of development of rancidity in meat as a result of irradiation may be of concern when meat is treated under aerobic conditions. At the highest dose indicated above for meat irradiated under anaerobic conditions (4 kGy), effects on the organoleptic attributes of mutton have been detected

    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.

    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.

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.

    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 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

    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 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

    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 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.)

    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.

    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

    The consumption of animal flesh food in Ethiopia has associated with cultural practices. Meat plays pivotal and vital parts in special occasions and its cultural symbolic weight is markedly greater than that accorded to most other food. Processing and cooking of poultry is a gender based duty and has socio-cultural roles. Ethiopians are dependent on limited types of animals for meats due to the taboo associated culturally. Moreover, the consumption of meat and meat products has a very tidy association with religious beliefs, and are influenced by religions. The main religions of Ethiopia have their own peculiar doctrines of setting the feeding habits and customs of their followers. They influence meat products consumption through dictating the source animals that should be used or not be used for food, and scheduling the days of the years in periodical permeation and restriction of consumptions which in turn influences the pattern of meat consumption in the country. In Ethiopia, a cow or an ox is commonly butchered for the sole purpose of selling within the community. In special occasions, people have a cultural ceremony of slaughtering cow or ox and sharing among the group, called Kircha, which is a very common option of the people in rural area where access of meat is challenging frequently.

    Full Text Available In the Republic of Croatia, game meat is consumed far less than meat of domestic animals. Yearly game meat consumption amounts to only 0.55 kg per household member. Consumers prefer meat of domestic animals, because it is cheaper, not paying attention to specific nutritive advantages of game meat. A research on the game meat market and consumers’ preferences was carried out on 101 examinees, chosen among inhabitants of Slavonia and Baranja. The majority of questioned inhabitants did consume game meat (92%, of whom 66% consider game meat to be of better quality than meat of domestic animals. Significant number of examinees considers game meat as healthy food, being also convinced that game was healthier to consume if hunted in their natural environment, than if reared on specialized farms (90%. Irrespective of quality, only 22% of examinees buy game meat, and 51% think such meat is too expensive. This is the main reason why consumers have game meat only once a month (51%. Taking into consideration monthly income of their respective household, 58% of examinees can afford game meat only once a month, and, if having an opportunity, they would opt for meat of roe deer (55% and rabbit (25%. When asked what would stimulate the game meat market in Croatia, 56% of examinees believe this could be achieved by lowering of prices, 27% think the issue could be addressed by opening of specialty stores, and only 17% opted for more aggressive marketing activities.

  6. Detection of dietary DNA, protein, and glyphosate in meat, milk, and eggs.

    2017-07-01

    Products such as meat, milk, and eggs from animals that have consumed genetically engineered (GE) feed are not currently subject to mandatory GE labeling requirements. Some voluntary "non-genetically modified organism" labeling has been associated with such products, indicating that the animals were not fed GE crops, as there are no commercialized GE food animals. This review summarizes the available scientific literature on the detection of dietary DNA and protein in animal products and briefly discusses the implications of mandatory GE labeling for products from animals that have consumed GE feed. Because glyphosate is used on some GE crops, the available studies on glyphosate residues in animal products are also reviewed. In GE crops, recombinant DNA (rDNA) makes up a small percentage of the plant's total DNA. The final amount of DNA in food/feed depends on many factors including the variable number and density of cells in the edible parts, the DNA-containing matrix, environmental conditions, and the specific transgenic event. Processing treatments and animals' digestive systems degrade DNA into small fragments. Available reports conclude that endogenous DNA and rDNA are processed in exactly the same way in the gastrointestinal tract and that they account for a very small proportion of food intake by weight. Small pieces of high copy number endogenous plant genes have occasionally been detected in meat and milk. Similarly sized pieces of rDNA have also been identified in meat, primarily fish, although detection is inconsistent. Dietary rDNA fragments have not been detected in chicken or quail eggs or in fresh milk from cows or goats. Collectively, studies have failed to identify full-length endogenous or rDNA transcripts or recombinant proteins in meat, milk, or eggs. Similarly, because mammals do not bioaccumulate glyphosate and it is rapidly excreted, negligible levels of glyphosate in cattle, pig and poultry meat, milk, and eggs have been reported. Despite

    A number of beneficial effects can be achieved by irradiating meats and poultry under different conditions. It is possible, for example, to extend the market life of both fresh and processed meats by applying radiation doses sufficient to reduce the microbial population, thereby delaying onset of spoilage; higher doses aimed at destroying both spoilage and pathogenic microorganisms can also be applied to meats, packaged to prevent recontamination, resulting in a shelf-stable product; the objective may also be to inactivate pathogenic bacteria, parasites and viruses in order to obtain a product which is acceptable from the point of view of public health.

    In recent years, much attention has been paid to develop meat and meat products with physiological functions to promote health conditions and prevent the risk of diseases. This review focuses on strategies to improve the functional value of meat and meat products. Value improvement can be realized by adding functional compounds including conjugated linoneleic acid, vitamin E, n3 fatty acids and selenium in animal diets to improve animal production, carcass composition and fresh meat quality. In addition, functional ingredients such as vegetable proteins, dietary fibers, herbs and spices, and lactic acid bacteria can be directly incorporated into meat products during processing to improve their functional value for consumers. Functional compounds, especially peptides, can also be generated from meat and meat products during processing such as fermentation, curing and aging, and enzymatic hydrolysis. This review further discusses the current status, consumer acceptance, and market for functional foods from the global viewpoints. Future prospects for functional meat and meat products are also discussed.

    2017-05-01

    Full Text Available The governmental initiative called the Compatriots Programme, which supports language tuition in Estonian schools and societies abroad, reveals an increased interest in developing intergenerational language transmission in the growing Estonian diaspora. This transnational language political activity signals a new era in language policy, where nation states are increasingly decentralized by migration. The evaluation of the program furthermore reveals that organizing such schools requires a willingness to take language political agency, typically conducted by well-educated and well-integrated resourceful transnational multilingual parents. The present article outlines the results of an ethnographic study of the process of establishing the Estonian School in Copenhagen. This step has demanded a change in the mindset still prevailing in Estonia that language political activities, such as planning language acquisition, are solely the responsibility of the state. Since the prevailing language ideology in Denmark is not favorable towards multilingualism in migrant languages, intergenerational language transmission furthermore presupposes a feeling of ownership of the language and high language self-esteem.

    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.

    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 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

    Autoradiographic and tracer techniques were employed to investigate the distribution and movement of radiomercury in the form of /sup 203/Hg-nitrate, and its transfer to eggs in laying quails. After injection, the radiomercury tended to concentrate in the kidneys and ova, plateauing about 12 hours after injection. Within the egg, the mercury concentrated in the yolk.

    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 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

    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.

    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.

    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.

    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.

  6. 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.

    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.

    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.

    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 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

    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.

    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

    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 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%.

    Estonian is a morphologically rich Finno-Ugric language with nominal paradigms that have at least 28 different inflected forms but sometimes more than 40. For languages with rich inflection, it has been argued that whole-word frequency, as a diagnostic of whole-word representations, should not be predictive for lexical processing. We report a lexical decision experiment, showing that response latencies decrease both with frequency of the inflected form and its inflectional paradigm size. Inflectional paradigm size was also predictive of semantic categorization, indicating it is a semantic effect, similar to the morphological family size effect. These findings fit well with the evidence for frequency effects of word n-grams in languages with little inflectional morphology, such as English. Apparently, the amount of information on word use in the mental lexicon is substantially larger than was previously thought. Copyright © 2018 Elsevier B.V. All rights reserved.

    Full Text Available The laser-induced breakdown spectroscopy (LIBS combined with multivariate regression analysis of measured data were utilised for determination of the heating value and the chemical composition of pellets made from Estonian oil shale samples with different heating values. The study is the first where the oil shale heating value is determined on the basis of LIBS spectra. The method for selecting the optimal number of spectral lines for ordinary multivariate least squares regression model is presented. The correlation coefficient between the heating value predicted by the regression model, and that measured by calorimetric bomb, was R2=0.98. The standard deviation of prediction was 0.24 MJ/kg. Concentrations of oil shale components predicted by the regression model were compared with those measured by ordinary methods.

    Full Text Available Recession has sharply erected the question of tax burden and the optimal proportion of different kinds of taxes among the incomes of the budget. Indirect taxes and consumption taxes, which proportion is different according to different methodologies, dominate in Estonian state budget. The buoyancy of a tax system based on taxes of that kind is especially weak during the recession. Difficulties concerning the incomes of budget have arisen the necessity for lifting taxes, which is possible as the tax burden is low now. But a sharp question of the optimal level of taxes is going to be raised. A formula for indirect tax optimum according to Ramsey taxes and Slutski decomposition has been proposed in the article.

    Full Text Available The article investigates the selection and sequencing of the idioms encountered in two locally-produced and international coursebook series currently employed in Estonian basic schools. It is hypothesized that there exists a positive correlation between idioms’ difficulty and coursebooks’ language proficiency level. The hypothesis is tested through a statistical analysis of the idioms found which are categorized in terms of their analysability into three categories where category 1 includes analysable semi-literal idioms, category 2 comprises analysable semi-transparent idioms, and category 3 encompasses non-analysable opaque idioms, and then analysed through an online language corpus (British National Corpus. The results of the study reveal that the coursebook authors under discussion have disregarded idioms’ frequency as a criterion for selection or sequencing, whereas the factor utilized to some extent is the degree of analysability.

    Full Text Available The purpose of the study was to find out whether the conceptual connection of emotion and motion is holding in the domain of personality traits. In a quantitative study 40 Estonian terms of personality traits were investigated and a conclusion was driven that, indeed, the qualities of emotionality and motion are perceived as co-present characteristics. In further data analysis some visualized measures were applied in order to get further insights into the hidden structure of the data. The self-organizing map (SOM analysis revealed an additional dimension of axiological evaluations present in the semantics and the SOM meta-analysis technique revealed groups of near synonymous words as well as gave overview of the more general structure common in the two data sets. The latter was tentatively explained by the person’s habitual level of activation.DOI: http://dx.doi.org/10.5128/ERYa6.21

    The aim of this paper is to compare the changes in the utilization of species from various hemeroby categories (indicating the degree of sensitivity of the plant to human impact) using historical data concerning the years 1888-1994. The authors digitised 8808 handwritten reports, reflecting local ethnopharmacological knowledge from 8 selected collections from the Estonian Folklore Archives of the Estonian Literary Museum. They were semi-quantitatively analyzed according to the sensitivity to human impact of 540 taxa that could possibly be related to the plant vernacular names given in the reports. Although in different periods of time the number of ethnopharmacologically used plants has changed, the proportion of plants utilized from each group has remained relatively same, consisting on average of: 23% anthropophytes, 42% apophytes, 32% hemeradiaphores and 3% hemerophobes. Comparison of the application of the most used plants revealed considerable changes of plant utilization, in which the varied use of the most popular anthropophytes increased and the applied scope of the most popular hemeradiaphores and hemerophobes decreased almost by twofold in one century. Case studies on seven taxa are presented, of them, use of Allium sativum L., Aesculus hippocastanum L. and Mentha xpiperita L. increased, whereas the use of Hordeum L., Orchidaceae, Paris quadrifolia L. and Briza media L. decreased greatly. This research contributes to the better understanding of the cognitive and human ecological concepts underlying the use of medicinal plants in Estonia. Strong increase in the ethnomedical utilization of plants depending on human influence, and a decrease in the use of taxa that do not prefer human activities indicates that, despite some of the population still have access to natural resources and diverse knowledge of the medical use of plants, the majority relies on a very narrow selection and a rather restricted herbal landscape.

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.

    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.

    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.

    2015-01-01

    The effect of radiation processing (0, 2.5, 5 and 10 kGy) on the tenderness of three types of popularly consumed meat in India namely chicken, lamb and buffalo was investigated. In irradiated meat samples dose dependant reduction in water holding capacity, cooking yield and shear force was observed. Reduction in shear force upon radiation processing was more pronounced in buffalo meat. Protein and collagen solubility as well as TCA soluble protein content increased on irradiation. Radiation processing of meat samples resulted in some change in colour of meat. Results suggested that irradiation leads to dose dependant tenderization of meat. Radiation processing of meat at a dose of 2.5 kGy improved its texture and had acceptable odour. - Highlights: • Effect of radiation processing on tenderness of three meat systems was evaluated. • Dose dependant reduction in shear force seen in buffalo meat. • Collagen solubility increased with irradiation

    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.

    Osteogenesis imperfecta (OI) is a rare bone disorder. In 90% of cases, OI is caused by mutations in the COL1A1/2 genes, which code procollagen α1 and α2 chains. The main aim of the current research was to identify the mutational spectrum of COL1A1/2 genes in Estonian patients. The small population size of Estonia provides a unique chance to explore the collagen I mutational profile of 100% of OI families in the country. We performed mutational analysis of peripheral blood gDNA of 30 unrelated Estonian OI patients using Sanger sequencing of COL1A1 and COL1A2 genes, including all intron-exon junctions and 5'UTR and 3'UTR regions, to identify causative OI mutations. We identified COL1A1/2 mutations in 86.67% of patients (26/30). 76.92% of discovered mutations were located in the COL1A1 (n = 20) and 23.08% in the COL1A2 (n = 6) gene. Half of the COL1A1/2 mutations appeared to be novel. The percentage of quantitative COL1A1/2 mutations was 69.23%. Glycine substitution with serine was the most prevalent among missense mutations. All qualitative mutations were situated in the chain domain of pro-α1/2 chains. Our study shows that among the Estonian OI population, the range of collagen I mutations is quite high, which agrees with other described OI cohorts of Northern Europe. The Estonian OI cohort differs due to the high number of quantitative variants and simple missense variants, which are mostly Gly to Ser substitutions and do not extend the chain domain of COL1A1/2 products.

  12. Radiation preservation of meat and meat products: A review.

    Dempster, J F

    1985-01-01

    The World Health Organisation (WHO) in 1980 clarified the position regarding the medical acceptability of irradiated foods when it said'…no health hazard results from consuming any food irradiated up to a dose of one megarad (1 Mrad)'. This resulted in renewed interest in irradiation as a cost-effective alternative to traditional preservation methods such as canning and freezing. Thus, radurisation (the application of ionising radiation at a dose level which substantially reduces the microbial population) increases the shelf life of poultry, comminuted meat and meat dishes significantly. Low dose irradiation, or radicidation, eliminates parasites such as Trichinae and cysticerci in pork and, very importantly, salmonella organisms in poultry and red meat. Therefore, irradiation has an important rôle to play in public health protection. High dose irradiation, or radappertisation ('cold sterilisation'), uses doses in excess of 1 Mrad and is analogous to retorting as understood in the canning industry. However, it can adversely affect quality in producing 'free radicals' in high protein foods such as meat. To prevent this, special precautions are necessary, e.g. irradiation is conducted at very low temperatures and the product is usually vacuum packed. A further potential use of irradiation is its ability to reduce the quantity of nitrite necessary in cured meats. This may become of practical significance if legislation further reduces the amount of nitrite permitted in these products. Copyright © 1985. Published by Elsevier Ltd.

    Full Text Available The consumption of snail meat goes back to prehistoric times. Different ancient nations had snails on their menu, but Helices culture as a productive activity was born as a Roman culture. Some of the most economically important edible species are: Helix aspersa (Mtiller Helixpomatia (Linne, Helix iucorum (Linne, Helix aperta (Born, Eobania vermiculata (Miiller. Together with its tasie, snail meat has several advantages over others: quite low lipid rate and calorie values versus rich mineral, essential amino acid and fatty acid content. The composition of snail meat is presented. In addition, the composition of different snail species and the part analyzed (pedal mass and visceral mass is presented. Also, the differences in composition according to the species (snail meat horse/chicken meat, beef, swine meat, fish meat are presented. The French are the world's leading consumers of snails. !n France snails come to market in a variety of ways. Estimated consumption of snails in France is around 40 000 tones/year. Total French imports account for 25% of world imports. France is also the leading exporter of prepared snails, mainly sold as preserved snails and prepared dishes. Snail imports have been much higher than exports (65 tones exported in 2002. vs. 2.700 tones imported. Despite the large consumption, only 3% of snails in France come from production (farming. Italy is in second place in the world consumption of snails, and Spain and Germany are in the third and fourth place. The development of snails consumption in Italy is followed with the same amount of production of snails in the whole biological circle. In 2001, from 24,700 tons, 9,350 tons (37.8% came from production, 6 00 tons (2.4% came from nature, and 14,750 tons (59.70% came from imports (frozen, fresh and prepared snails.

    2013-01-01

    Full Text Available The purpose of the study is to evaluate how supportive is Estonian national innovation system toward the launching of new innovative products by high technology firms. The article intends to combine two broad areas of research – national innovation system approach and the different models of the new product launching. Based on the literature review and in-depth analysis of three case studies of Estonian high-tech company’s major barriers as well success factors of highly innovative product launches were identified. The barriers of the new product launching were linked with the systemic failures of the national innovation system. The most relevant failures of Estonian national innovation system inhibiting the new product development are capability and networking failures. The sources of innovation of high-technology firms are too narrow, linkages with domestic firms and higher education institutions as well with foreign firms are poorly developed. High-tech firms have also serious capacity problems due to the extremely weak support mechanism by national innovation system on the seed funding stage of product development and prototype building stage as well. Paper argues that resources needed for the innovation should not be looked too narrowly following linear innovation model approach. Instead interactive approach is needed, which combines capability building, network development, interactive learning with direct investments into fundamental research.

    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.

    Frozen southern bluefin tuna meat discolors easily and sometimes contracts when thawed caused by thaw rigor. These phenomenon often become problematic in the transaction or handling of this kind of frozen tuna. Frozen meat blocks of southern Bluefin tuna were thawed separately by air thawing, running water thawing and microwave thawing. Changes occurring during thawing were checked for meat color by met-myoglobin ratio determination and for contract by microscopic observation. Results are as follows : (1) Discoloration scarcely occurred in the process of running water thawing (at 10°C for 50 min, or at 0°C for 6 hr). (2) No contraction was observed during thawing with running water described above and air thawing (at 18-20°C for 6 hr). (3) Discoloration and contraction seemed to be minimized, as to latently contractile blocks, when meat temperature passed through rapidly between -10°C and -5°C, and slowly (for 5-6 hr) between -5°C and -1°C. When the block was originally not contractile, discloration was minimized by rising meat temperature rapidly from -10°C to -l°C.

    Full Text Available The article discusses three Estonian translations of Daniel Defoe’s Robinson Crusoe into Estonian with the focus on the completeness of the translated texts and the characterisation given to these in paratextual information. While there are several translations and versions of the tex t available in E stonian that have either used a mediating language or do not proceed directly from Defoe’s novel, three editions explicitly list Defoe’s English-language Robinson Crusoe as their source text. These are Rudolf Sirge’s translation from 1950 and two editions translated by Valter Rummel that appeared in 1984 (reprinted in 2001 and 2007, respectively. The article sets out to discover the main differences between the three editions and the possible reasons that may have triggered their publication in Estonia at those particular times. In order to approach the issues, a general framework derived from descriptive translation studies is employed with an emphasis on Gideon Toury’s chrestomatic treatment of translation norms. Thus an attempt is made to detect the preliminary translational norms regarding translation policy, particularly the choice of texts to be translated, as well as the matricial norms that concern the fullness of the translated text and are part of operational norms manifested in the translator’s decisions which, in two of the cases at hand, may also have been decisions made by the editor or the censor. Rudolf Sirge’s translation appeared at a time when Estonia had fairly recently been incorporated into the Soviet Union and there was a lack of children’s literature ideologically appreciated by the regime. This may account for the packaging of the book as a work with a strong didactic bent, while its primary audience was taken to be children and young adults for whom the protagonist served as an example of a hard-working and tenacious hero to be emulated by young Soviets.

    In recent years, much attention has been paid to physiological functions of foods due to increasing concerns for health. Although there has been limited information of physiological functions of meat until recently, several attractive meat-based bioactive compounds, such as carnosine, anserine, l-carnitine, conjugated linoleic acid, have been studied. Emphasizing these activities is one possible approach for improving the health image of meat and developing functional meat products. This article provides potential benefits of representative meat-based bioactive compounds on human health and an overview of meat-based functional products. Strategies for designing novel functional meat products utilizing bioactive peptides and/or probiotic bacteria, is also discussed. This article focuses particularly on the possibility of meat protein-derived bioactive peptides, such as antihypertensive peptides. There are still some hurdles in developing and marketing novel functional meat products since such products are unconventional and consumers in many countries recognize meat and meat products to be bad for health. Along with accumulation of scientific data, there is an urgent need to inform consumers of the exact functional value of meat and meat products including novel functional foods.

    Full Text Available In this paper, we compare the use and functions of definite and indefinite article-like determiners in Estonian and Finnish. Our main aim is to explore whether the factors that explain the choice of particular determiner forms are similar in Estonian and Finnish. We use a picture-sequence based elicitation experiment to collect spoken narratives from adult native speakers of Estonian and Finnish, and apply non-parametric tree and forest models to analyze the data. Our findings indicate that number of mention and animacy are important predictor variables in both languages, but their exact effect is divergent. We also find that in Finnish, case of the determiner NP proves to be an important factor, while in Estonian, syntactic role of the NP explains some aspects of determiner form choice. Nevertheless, the overall usage frequency of determiners is modest in the Estonian and Finnish data, and the process of grammaticalizing articles is only in initial stages in both languages. *** Artikliga, artiklita?

    Ultrasound has a wide range of applications in various agricultural sectors. In food processing, it is considered to be an emerging technology with the potential to speed up processes without damaging the quality of foodstuffs. Here we review the reports on the applications of ultrasound specifically with a view to its use in meat processing. Emphasis is placed on the effects on quality and technological properties such as texture, water retention, colour, curing, marinating, cooking yield, freezing, thawing and microbial inhibition. After the literature review it is concluded that ultrasound is a useful tool for the meat industry as it helps in tenderisation, accelerates maturation and mass transfer, reduces cooking energy, increases shelf life of meat without affecting other quality properties, improves functional properties of emulsified products, eases mould cleaning and improves the sterilisation of equipment surfaces.

    Eggs of Japanese quail (Coturnix coturnix japonica) were irradiated before incubation with doses of 300, 500, 800, 1500, 2000 and 2500 R of /sup 60/Co gamma rays at a dose rate of 187 R/min. The parameters of hatchability, embryonic morphology in the last phases of development, growth changes, viability, sex ratio and production of eggs in the control and experimental groups were followed. Embryonic mortality was proportional to the dose, irradiation weakened the embryos, at doses of 800 R and more the radiation evoked various teratogenic changes and slightly lengthened the incubation period. For the period of embryonic development, LD/sub 50/ approximately equal to 800 R and LD/sub 100/=2500 R was determined. Radiation slightly suppressed growth, viability in the postembryonic stage was influenced very slightly. Irradiation of eggs did not influence the sex ratio; the production of eggs was significantly reduced only at a dose of 1500 R and more.

    1982-01-01

    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.

    Gupta, S; Upadhyay, R; Kanungo, M S

    1998-11-01

    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.

  13. Diurnal rhythm of pituitary gonadotropic activity of male Japanese quail in relation to testicular growth

    International Nuclear Information System (INIS)

    Hashiguchi, Mineo; Koga, Osamu; Nishiyama, Hisayoshi

    1977-01-01

    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.

    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.

  15. Enterococci Isolated from Japanese Quails Exposed to Microgravity Conditions and Stability of their Properties

    2009-01-01

    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.

    Background: Meat cooking conditions in in vitro and in vivo models have been shown to influence the rate of protein digestion, which is known to affect postprandial protein metabolism in the elderly. Objective: The present study was conducted to demonstrate the effect of cooking conditions on meat protein assimilation in the elderly. We used a single-meal protocol to assess the meat protein absorption rate and estimate postprandial meat protein utilization in elderly subjects. Design: The study recruited 10 elderly volunteers aged 70-82 y. Each received, on 2 separate occasions, a test meal exclusively composed of intrinsically 15 N-labeled bovine meat (30 g protein), cooked at 55°C for 5 min [rare meat (RM)] or at 90°C for 30 min [fully cooked meat (FCM)], and minced. Whole-body fluxes of leucine, before and after the meal, were determined with the use of a [1- 13 C]leucine intravenous infusion. Meat protein absorption was recorded with the use of 15 N enrichment of amino acids. Results: Postprandial time course observations showed a lower concentration in the plasma of indispensable amino acids ( P meat leucine in the plasma ( P meat nitrogen to plasma amino acid nitrogen ( P meat amino acids with RM than with FCM. This was associated with decreased postprandial whole-body protein synthesis with RM than with FCM (40% compared with 56% of leucine intake, respectively; P meat cooking conditions have little effect on postprandial protein utilization in young adults, the present work showed that the bioavailability and assimilation of meat amino acids in the elderly is lower when meat is poorly cooked. In view to preventing sarcopenia, elderly subjects should be advised to favor the consumption of well-cooked meat.

    2006-01-01

    This study was designed to examine the levels of serum protein fractions and testosterone, in addition to histopathological changes of small intestine and liver of Japanese quail following feeding with diets containing different concentrations of boiled oil (BO). 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

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

    Toomey, Matthew B; McGraw, Kevin J

    2007-09-01

    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.

    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

  9. Appraisal and standardization of curvilinear velocity (VCL) cut-off values for CASA analysis of Japanese quail (Coturnix japonica) sperm.

    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.

    In 2007 the World Cancer Research Fund and American Institute for Cancer Research (WCRF/AICR) report judged that the evidence for an association between red and processed meat consumption and colorectal cancer was convincing. In addition, the effect of other animal products on cancer risk has been studied, and the WCRF/AICR report concluded that milk probably decreases the risk of colorectal cancer but diets high in calcium probably increase the risk of prostate cancer, whereas there was limited evidence for an association between milk and bladder cancer and insufficient evidence for other cancers. There are several potential mechanisms relating meat to cancer, including heterocyclic amines, polycyclic aromatic hydrocarbons, N-nitroso compounds, and heme iron. Although the evidence in favor of a link between red and processed meat and colorectal cancer is convincing, the relations with other cancers are unclear. In this review, we summarize cohort studies conducted by the National Cancer Institute on meat and dairy intake in relation to cancer since the 2007 WCRF/AICR report. We also report the findings of meta-analyses published since 2007. PMID:24847855

    Nutrient fluctuations during the fetal stage affects fetal development, which has long-term impacts on the production efficiency and quality of meat. During the early development, a pool of mesenchymal progenitor cells proliferate and then diverge into either myogenic or adipogenic/fibrogenic lineages. Myogenic progenitor cells further develop into muscle fibers and satellite cells, while adipogenic/fibrogenic lineage cells develop into adipocytes, fibroblasts and resident fibro-adipogenic progenitor cells. Enhancing the proliferation and myogenic commitment of progenitor cells during fetal development enhances muscle growth and lean production in offspring. On the other hand, promoting the adipogenic differentiation of adipogenic/fibrogenic progenitor cells inside the muscle increases intramuscular adipocytes and reduces connective tissue, which improves meat marbling and tenderness. Available studies in mammalian livestock, including cattle, sheep and pigs, clearly show the link between maternal nutrition and the quantity and quality of meat production. Similarly, chicken muscle fibers develop before hatching and, thus, egg and yolk sizes and hatching temperature affect long-term growth performance and meat production of chicken. On the contrary, because fishes are able to generate new muscle fibers lifelong, the impact of early nutrition on fish growth performance is expected to be minor, which requires further studies.

    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

    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.

    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.

    Two 9-year old Estonian Salix plantations suffering from dieback were studied: one situated on poor mineral soil and divided into fertilised and unfertilised plots (Saare plantation) and another growing on a well-decomposed and nitrogen-rich organic soil, without fertiliser application (Kambja plantation). Bacteria from internal tissues of visually damaged shoots from seven clones were isolated in spring and autumn. The strains were subsequently biochemically characterised and tested for ice nucleation activity and pathogenicity on Salix. Some strains were also analysed with 16S rRNA. High numbers of culturable bacteria were found, belonging mainly to Erwinia, Sphingomonas, Pseudomonas and Xanthomonas spp. Fertilised plots were significantly more colonised by bacteria than unfertilised plots and also more extensively damaged, showing a lower density of living plants after 7 years of culture. More ice nucleation active (INA) strains were found in Saare fertilised plots and at Kambja than in Saare unfertilised plots. Likewise, most pathogenic strains were isolated from Saare fertilised plots and from Kambja. For some of the willow clones studied, dieback appeared to be related to both clonal frost sensitivity and abundance of INA and pathogenic bacteria. The plantations probably suffered from the presence of high amounts of pathogens and from frost related injuries aggravated by INA bacteria. Most probably the fertilisation at Saare and the nitrogen-rich soil at Kambja created a favourable environment for bacterial development and led to high dieback levels after the first harvest.

  20. Estonian energy system: Proposals for the implementation of a cogeneration strategy

    Since the Soviet era Estonia inherited oil-shale-based electricity plants, with a capacity of 3000 MW. Oil shale now provides Estonia with very low electricity prices. However, most of the stations are very old. Half of them were built before 1965, and sooner or later the old oil shale production units will have to be replaced. Estonia will then have to face serious increases in electricity production prices. At the same time Estonia has problems in restoring its district heating systems. The prices are rising and may consumers have converted to other heating sources such as electric heating. The major long-term strategic policy choices to make in Estonia are to decide (1) whether the oil shale power stations should be replaced by new centralized production units such as new oil shale stations or nuclear power, or (2) whether the electricity production should be decentralized. In the centralized solution (oil shale or nuclear power), the domestic heating will be left to boilers or electric heating leading to a very high primary energy supply. In the decentralized solution, Estonia could benefit from the advantage of cogeneration leading to very low fuel consumption. But this latter strategy depends on the restoration of the district heating systems. This article seeks to form a strategy to improve the efficiency of the Estonian energy system by increasing the use of cogeneration. (author)

    Factors affecting Estonian forests are: The environmental, specially atmospheric pollution, - the foundation of new forests as monoculture on unsuitable locations, - mechanical damages by unsuitable forest machinery, - unfavourable water conditions, - Heterobasidion or Armillaria rot roots. Local damages in consequence of air pollutants are distributed in environments of Tallinn, Kivioli, Kohtla-Jaerve and the thermal power stations (Narva), where the SO 2 -content in the air is on the average higher than 50 (80) μg/m 3 . Pine forests on dry sand soils (600 ha damaged in 1989) and the older spruce forests show the new type of forest decline. High Al-ion concentration, disturbances of the Ca-Mg-metabolism, an extreme nutrient deficit, (specially N-deficit) and periodical water deficit as well as pathogenic fungi are damaging the trees. Spruces show nonspecific defoliation, needle necrosis, needlefall, occurence of fungal diseases. More damaged are the spruce forests in regions with basic precipitations and high sulphur-deposition.

    To examine factors associated with early sexual intercourse among 15 to 16-year-old adolescents by gender. The data were collected from a random sample of Estonian basic schools' ninth grade pupils in 1999 using self-completed questionnaires. A multivariate logistic regression analysis for boys and girls was used to test for associations between sexual intercourse, and personal gender role-related attitudes, attitudes towards sexual intercourse, pubertal timing, smoking status and experience of drunkenness. Of the respondents, 14.6% of boys and 13.1% of girls had experienced sexual intercourse. Traditional gender role-related attitudes were associated with sexual intercourse among girls, but not among boys. Smoking and experience of drunkenness was strongly associated with sexual intercourse for both genders. Gender differences in the association between gender role-related attitudes and early sexual intercourse were observed among 15 to 16-year-olds in Estonia. Smoking and experience of drunkenness were strongly related to sexual intercourse for both genders.

    The present paper is based on a WHO Collaborative Cross-National Study "Health Behavior in School-Aged Children (HBSC)." It aimed at describing and analyzing how the sexual behaviors of 13- to 15-year-old Estonian school children were associated with self-reported depressive feelings and suicidality. Distinctive behavioral traits in relation to age of first sexual intercourse were also investigated. Self-reported questionnaires from school children (n = 3,055) were analyzed. In total, 15.2% of school children reported being nonvirgin. Among 13-year-olds, 2.9% of girls and 6.8% of boys were nonvirgins. Approximately 25% of the 15-year-old girls and boys were nonvirgins. The likelihood of depressive feelings and suicidal ideation increased significantly in both genders with loss of virginity. Boys who had lost their virginity at 13 years or younger were 4.2 times more likely to have suicidal thoughts; comparable girls were 7.8 times more likely to have suicidal thoughts. Compared to virgins, youths who had lost their virginity reported poor self-assessed health and more risk behaviors in themselves and their peers. Experiences of sexual intercourse increased the odds ratios for depressive feelings and suicidality. The earlier sexual intercourse was initiated, the greater were the odds of lower mental well-being. Risk behaviors emerged as a complex phenomenon requiring complex prevention.

    Full Text Available The paper analyses issues related to supervision and support of early career researchers in Estonian academia. We use nine focus groups interviews conducted in 2015 with representatives of social sciences in order to identify early career researchers’ needs with respect to support, frustrations they may experience, and resources they may have for addressing them. Our crucial contribution is the identification of wider support networks of peers and colleagues that may compensate, partially or even fully, for failures of official supervision. On the basis of our analysis we argue that support for early career researchers should take into account the resources they already possess but also recognise the importance of wider academic culture, including funding and employment patterns, and the roles of supervisors and senior researchers in ensuring successful functioning of support networks. Through analysing the conditions for the development of early career researchers – producers of knowledge – our paper contributes to social epistemology understood as analysis of specific forms of social organisation of knowledge production.

    This review examines the chemistry of nitrite curing of meat and meat products as it relates to the development of cured meat color and provides a detailed account of how nitrite-free processed meats could be prepared using the preformed cooked cured-meat pigment (CCMP). Thus, a chemical description of meat color, both raw and cooked, and characterization of nitrosylheme pigments follows. Based on electron paramagnetic resonance (EPR), visible and infrared spectroscopic studies, evidence has been provided to support the hypothesis that the chemical structure of the preformed CCMP is identical to that of the pigment prepared in situ after thermal processing of nitrite-cured meat and is in fact a mononitrosylheme complex. An appendix, which describes the basic principles of EPR spectroscopy used in the context of this review, is attached.

    The effect of radiation processing (0, 2.5, 5 and 10 kGy) on the tenderness of three types of popularly consumed meat in India namely chicken, lamb and buffalo was investigated. In irradiated meat samples dose dependant reduction in water holding capacity, cooking yield and shear force was observed. Reduction in shear force upon radiation processing was more pronounced in buffalo meat. Protein and collagen solubility as well as TCA soluble protein content increased on irradiation. Radiation processing of meat samples resulted in some change in colour of meat. Results suggested that irradiation leads to dose dependant tenderization of meat. Radiation processing of meat at a dose of 2.5 kGy improved its texture and had acceptable odour.

  7. Main Concerns of Pathogenic Microorganisms in Meat

    Although various foods can serve as sources of foodborne illness, meat and meat products are important sources of human infections with a variety of foodborne pathogens, i.e. Salmonella spp., Campylobacter jejuni/coli, Yersinia enterocolitica, Verotoxigenic E. coli and, to some extent, Listeria monocytogenes. All these may be harboured in the gastrointestinal tract of food-producing animals. The most frequent chain of events leading to meat-borne illness involves food animals, which are healthy carriers of the pathogens that are subsequently transferred to humans through production, handling and consumption of meat and meat products. Occurrences of Salmonella spp., C. jejuni/coli, Y. enterocolitica and Verotoxigenic E. coli in fresh red meat vary relatively widely, although most often are between 1 and 10%, depending on a range of factors including the organism, geographical factors, farming and/or meat production practices.

    The World Cancer Research Fund (WCRF) recommended in 2007 that consumer intake of red meat is minimized and processed meat eliminated. The recommendation was based on a systematic review of the available literature on the association between meat consumption and cancer. The recommendation...... to individuals was to ingest less than 500 grams of red meat per weeks, and very little - if anything - processed meats. In a new study, National Food Institute has assessed the nutritional consequences from living the recommendations of the WCRF, in Norway, Sweden, Finland and Denmark. The current consumption...... of meat in the Nordic countries is not far from the level WCRF has proposed on an individual level. The study also shows that it will have no significant nutritional consequences to reduce the intake of meat to the recommended, neither when it comes to red meat nor processed meat....

  9. Of Meat and Men: Sex Differences in Implicit and Explicit Attitudes Toward Meat

    Directory of Open Access Journals (Sweden)

    Hamish J. Love

    2018-04-01

    Full Text Available Modern attitudes to meat in both men and women reflect a strong meat-masculinity association. Sex differences in the relationship between meat and masculinity have not been previously explored. In the current study we used two IATs (implicit association tasks, a visual search task, and a questionnaire to measure implicit and explicit attitudes toward meat in men and women. Men exhibited stronger implicit associations between meat and healthiness than did women, but both sexes associated meat more strongly with ‘healthy’ than ‘unhealthy’ concepts. As ‘healthy’ was operationalized in the current study using terms such as “virile” and “powerful,” this suggests that a meat-strength/power association may mediate the meat-masculinity link readily observed across western cultures. The sex difference was not related to explicit attitudes to meat, nor was it attributable to a variety of other factors, such as a generally more positive disposition toward meat in men than women. Men also exhibited an attention bias toward meats, compared to non-meat foods, while females exhibited more caution when searching for non-meat foods, compared to meat. These biases were not related to implicit attitudes, but did tend to increase with increasing hunger levels. Potential ultimate explanations for these differences, including sex differences in bio-physiological needs and receptivity to social signals are discussed.

    Full Text Available Changes in the Estonian National Museum from 1909 to the presentThe Estonian National Museum was founded in Tartu in 1909 as part of the national movement. With its activities and connections in society, the ENM helped create Estonian society, the nation’s collective memory and identity.The ENM has always been – despite the changing locations, names, and content – one of the symbols of national identity. But at the same time, ENM has never had its own building designed specially for the museum’s purposes.Since 1909 there have been several attempts to establish a home for the ENM. At first (1909–1923, Estonian society wanted to establish the museum in the center of Tartu. The museum was intended to become a key institution of the growing nation and establishing the nation’s identity.At last in 1923 the ENM secured the Raadi manor, outside the center of the city, in a beautiful park, near the lake with its boats and water attractions. In this manor the first permanent exhibition of mainly 19th century Estonian peasant life was compiled, and the ENM operated in the Raadi manor from 1923–1940 as the “Estonian’s own museum” The years of alternating occupations, World War II, and political terror damaged and destroyed the whole society. The Raadi manor was destroyed in the war too, and the ENM itself was divided into two parts – the State Ethnographic Museum and the State Literary Museum. The collections of the ENM were given to Tallinn and to many different places inside and outside Tartu. Then began “the period of temporary location” that continues today. The museum is located in several places in the city of Tartu.In 1988, the prior name of the State Ethnographic Museum – the Estonian National Museum – was reinstated. Since the 1990s there have been many attempts to secure a special building for the ENM. Now, at last, as a result of serious economic pressure, we are closer to this goal than ever.

    1985-01-01

    This paper highlights the importance of food irradiation in the protection of the public against food poisoning from eating meat or meat products contaminated with salmonella. Salmonella infections are increasing at an alarming rate (2000 in 1952 to 12000 reported cases in 1982 in England and Wales alone). Dr. Dempster reports that 50% of the chicken carcasses examined by workers in America were found to be salmonella contaminated. Use of irradiation in conjunction with mild refrigeration can extend the shelf-life of vacuum packed chicken by a factor of three. Important legislation now under discussion in the U.S.A. is likely to extend the applicability of food irradiation rapidly in the near future

    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. This research also detects the serovar of A. paragallinarum using hemagglutination inhibition test. The antibiotic sensitivity tests were also performed using several antibiotics against five A. paragallinarum isolates that were cultured on Mueller-Hinton Agar and added with antibiotic discs, then incubated in 5% CO2 at 37°C for 24-48 h. Results: Five isolates out of nine suspected isolates (55.5% were A. paragallinarum. The growth of isolates from quails did not depend on the nicotinamide adenine dinucleotide (NAD (NAD-independent. Sensitivity test was done using the five identified A. paragallinarum isolates, results showed that they were 100% sensitive to amoxicillin (AMC and ampicillin (AMP; 100% resistant toward amikacin (AK, erythromycin (E, gentamycin (CN, and tetracycline (TE; 80% resistant toward kanamycin (K and trimethoprim (W; 60% resistant toward chloramphenicol (C; and 20

    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.

    Awareness of health and nutrition has led to the development of "functional foods" which is a new approach to achieve healthier status thus reducing the risk of diseases. Meat has been highly exploited as a functional ingredient/food in recent years wherein meat has either been modified or incorporated into non meat products. Changing consumer demand has influenced the market for all types of meat. The development and marketing the functional foods can be, however, very challenging compared to the foods that conventionally have a high health image. This review gives the overall perception about importance of using meat/meat products as a functional food.

    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. Performance was evaluated through egg weight (EWg, egg yield (%Laying., egg mass (EMg/bird/day, feed intake (FIg/bird/day, feed conversion (FCkg/dz and FCkg/kg and mortality (%Mort. No significant statistical differences about the performance (P>0.05 were found. There was a significant effect (P<0.05 of the density for daily feed intake with

    Meat and meat products is one of the most relevant food groups in an important number of human diets. Recently, the IARC, based on results of a number of epidemiological studies, classified the consumptions of red meat and processed meat as "probably carcinogenic to humans" and as "carcinogenic to humans", respectively. It was suggested that the substances responsible of the potential carcinogenicity would be mainly generated during meat processing, such as curing and smoking, or when meat is heated at high temperatures. However, the exposure to environmental pollutants through meat consumption was not discussed. The purpose of the present paper was to review recent studies reporting the concentrations of PCDD/Fs, DL-PCBs and PAHs in meat and meat products, as well as the human exposure to these pollutants through the diet. It is concluded that the health risks derived from exposure to carcinogenic environmental contaminants must be considered in the context of each specific diet, which besides meat and meat products, includes other foodstuffs containing also chemical pollutants, some of them with carcinogenic potential. Anyhow, meat and meat products are not the main food group responsible of the dietary exposure to carcinogenic (or probably carcinogenic) environmental organic pollutants.
