  1. D-penicillamine exhibits a higher radioprotective effect in suckling mice than in grown-up animals

    International Nuclear Information System (INIS)

    Grown-up and suckling mice were exposed to whole-body 60Co-irradiation of 6-10 Gy. The survival time was significantly increased in suckling animals by 3000 mg per kg body weight D-penicillamine applied intraperitoneally 60 min before irradiation, whereas the same treatment had no significant effect in grown-up animals.

    Milk with a high concentration of fat and casein is required for cheese production, and these components have a major impact for both quality and yield of the curd. Recent observations have shown that suckling can elevate milk fat concentration in goats and our aim was therefore to check the hypothesis that animal welfare and cheese-processing properties of goat milk could be optimised by appropriate management of suckled/milked goats. Twelve Swedish dairy goats were kept together with one kid each in 4 different mixed management-systems (milking combined with partial suckling) in a cross-over design. Two milk accumulation intervals were tested; Short = dams and kids were together for 16 h (T16) and Long = ; dams and kids were together for 8 h (T8 h). In addition, two milking regimes were used; Suckled Before Milking = S and Milked Before Suckling = M. Milk accumulation interval referred to how long dams and kids were separated. The milk yield available for processing (milk offtake), was weighed and analysed from each milking occasion and the suckled milk yield was estimated by a weigh-suckle-weigh method (WSW) in combination with observing the suckling behaviour during the free suckling periods. Milking managements, such as 'suckling before milking (S)', increased milk fat concentration compared to milking before suckling (M) and 'Short accumulation treatments (T16)' gave higher milk fat, casein concentration and individual curd yield (%) compared to the 'Long accumulation treatment (T8)'. The total individual curd yield (g) was the same despite treatment, but the animal welfare was most likely higher in T16 where dams and kids spent more time together. PMID:27056664

  3. Haemolysis and perturbations in the systemic iron metabolism of suckling, copper-deficient mosaic mutant mice - an animal model of Menkes disease.

    Full Text Available The biological interaction between copper and iron is best exemplified by the decreased activity of multicopper ferroxidases under conditions of copper deficiency that limits the availability of iron for erythropoiesis. However, little is known about how copper deficiency affects iron homeostasis through alteration of the activity of other copper-containing proteins, not directly connected with iron metabolism, such as superoxide dismutase 1 (SOD1. This antioxidant enzyme scavenges the superoxide anion, a reactive oxygen species contributing to the toxicity of iron via the Fenton reaction. Here, we analyzed changes in the systemic iron metabolism using an animal model of Menkes disease: copper-deficient mosaic mutant mice with dysfunction of the ATP7A copper transporter. We found that the erythrocytes of these mutants are copper-deficient, display decreased SOD1 activity/expression and have cell membrane abnormalities. In consequence, the mosaic mice show evidence of haemolysis accompanied by haptoglobin-dependent elimination of haemoglobin (Hb from the circulation, as well as the induction of haem oxygenase 1 (HO1 in the liver and kidney. Moreover, the hepcidin-ferroportin regulatory axis is strongly affected in mosaic mice. These findings indicate that haemolysis is an additional pathogenic factor in a mouse model of Menkes diseases and provides evidence of a new indirect connection between copper deficiency and iron metabolism.

    Understanding the behavior of endangered species is crucial to improve the management tools to breed animals in captivity and, thus, to increase the success of ex situ conservation programs. In this study, we monitored suckling behavior of 26 cubs born between 2008 and 2012 at "El Acebuche" Iberian Lynx Breeding Centre. The cubs devoted 251 ± 19.7 min (mean ± SE) to lactation on the day of birth, while mothers spent 426 ± 27 min (mean ± SE) nursing their offspring. The time cubs spent suckling decreased exponentially as they grown, until they were fully weaned at 65 ± 2.6 days. The onset of weaning (first intake of solid food) occurred at 54 ± 1.35 days (mean ± SE). Thus, the strict lactation period occupied most of the overall lactation period. Both suckling and maternal behavior were affected by litter size. In twins and triplets, the competition between siblings caused a decrease in the time spent suckling, in spite of the mothers spending more time nursing their young. Finally, no significant differences were found in time spent suckling between littermates or depending on the sex of the cub. Lactation appeared to play a key role in the nutrition of the Iberian lynx and should therefore be conveniently managed in captive breeding programs of this threatened species.

  6. 26Al incorporation into the tissues of suckling rats through maternal milk

    International Nuclear Information System (INIS)

    Aluminium (Al) is highly neurotoxic and inhibits prenatal and postnatal development of the brain in humans and experimental animals. However, Al incorporation into the brain of sucklings through maternal milk has not yet been well clarified because Al lacks a suitable isotope for radioactive tracer experiments. Using 26Al as a tracer, we measured 26Al incorporation into the brain of suckling rats by accelerator mass spectrometry. Lactating rats were subcutaneously injected with 26AlCl3 from day 1 to day 20 postpartum. Suckling rats were weaned from day 21 postpartum. From day 5 to day 20 postpartum, the 26Al levels measured in the brain, liver, kidneys and bone of suckling rats increased significantly. After weaning, the amounts of 26Al in the liver and kidneys decreased remarkably. However, the 26Al amount in the brain had diminished only slightly up to 140 days after weaning

    1988-10-01

    Brahman cows (n = 49) and primiparous heifers (n = 11), Brahman x Hereford primiparous F1 heifers (n = 86) and Simmental x Brahman primiparous F1 heifers (n = 13) were randomly allotted by breed, age and date of calving to one of eight treatment groups: 1) control; 2) once-daily suckling; 3) lasalocid (200 mg/hd/d); 4) alfaprostol (5 mg intermuscular injections on Days 21 and 32 post partum); 5) lasalocid + once-daily suckling; 6) alfaprostol + once daily suckling; 7) alfaprostol + lasalocid; 8) alfaprostol + lasalocid + once daily suckling. All animals received 2.3 kg/hd/d of a concentrate (6 corn : 1 cottonseed meal) and lasalocid was mixed and fed in the concentrate. Body weights and condition scores were taken on Day 1 post partum and every 28 d thereafter. All animals were maintained with sterile marker bulls with Brahman and Simmental x Brahman cattle artificially inseminated at first estrus. Blood samples were collected at weekly intervals starting on Day 21 post partum until estrus and at nine to twelve days post estrus when the ovaries were palpated for corpora lutea. After the first postpartum estrus with a corpora lutea, cows were placed with fertile bulls. Mean serum progesterone concentrations were below 0.5 ng/ml prior to treatment. Calf weight gains to 90 d were not affected by age (P > 0.10) but were lower in the once-daily suckling group (P 0.10). Cows had a shorter postpartum interval (P 0.10) but did increase the cumulative frequency of return to estrus by 90 d post partum (P 0.10). Both once-daily suckling and alfaprostol were effective in increasing the numbers of animals inseminated by 90 d post partum. The once-daily suckling + alfaprostol treatment resulted in the shortest postpartum interval. PMID:16726521

    Full Text Available The experimental animals were 18 Cinta Senese sows (7 primiparous and 11 multiparous and relative purebred off-  spring. Individual weight of piglets was recorded at birth (or shortly afterwards to the nearest 50 g and subsequently  every 3-5 days up to weaning. At each recording, piglets were ranked in decreasing order according to weight within their  respective litters. The behavior of a subsample of 8 sows and litters was observed during suckling, by recording the  teat–piglet coupling. The sows had 12 functional teats, equally distributed in the two symmetric rows, that were num-  bered as pairs in the antero-posterior direction.  Starting from the third week, piglets of multiparous sows showed a faster growth rate than those of the primiparous ones.  Repeatability of the piglets’ weight during the suckling period was high (r = 0.56 and repeatability of rank was even  higher, but decreased up to weaning. Anterior teats were the most occupied and showed the highest suckling fidelity  (consistency of suckling position. Various statistical analyses about the dependence of piglet weight (or weight rank with-  in litter on teat order indicated the highest milk productivity of the first teats and the lowest of the 5th & 6th teat pairs.

  10. The Suckling Rat as a Model for Immunonutrition Studies in Early Life

    2012-01-01

    Full Text Available Diet plays a crucial role in maintaining optimal immune function. Research demonstrates the immunomodulatory properties and mechanisms of particular nutrients; however, these aspects are studied less in early life, when diet may exert an important role in the immune development of the neonate. Besides the limited data from epidemiological and human interventional trials in early life, animal models hold the key to increase the current knowledge about this interaction in this particular period. This paper reports the potential of the suckling rat as a model for immunonutrition studies in early life. In particular, it describes the main changes in the systemic and mucosal immune system development during rat suckling and allows some of these elements to be established as target biomarkers for studying the influence of particular nutrients. Different approaches to evaluate these immune effects, including the manipulation of the maternal diet during gestation and/or lactation or feeding the nutrient directly to the pups, are also described in detail. In summary, this paper provides investigators with useful tools for better designing experimental approaches focused on nutrition in early life for programming and immune development by using the suckling rat as a model.

    50 goats of several breeds and crossbreeds as well as their kids were observed. The experiment involved 388 hours of observation over 62 days. The average duration of pregnancy was 151.2 days. In addition to physical characteristics and labored mobility, a tendency toward isolation and characteristic vocalization were noted. The period from onset of birth to the first delivery averaged less than 20 min. Subsequent to delivery the doe arose immediately, followed by the kid in an average of 21 min. Initial suckling by the kids occurred on average 42 min after birth. After an initially high frequency of suckling cycles, the cycle in the following weeks was reduced to 1 to 2 times an hour in the case of a single kid birth, while twins suckled more often. Out of 5,562 observations, only 1% were true cases of suckling from another doe. PMID:2617523

    The effect of prenatal alcohol exposure on nipple attachment behavior was studied at a number of ages in rat pups whose mothers consumed liquid diets containing 35% or 0% ethanol-derived calories (EDC) or standard lab chow during pregnancy. In the first experiment, nondeprived pups were tested in groups of three (one from each of the prenatal treatment groups) for nipple attachment to an anesthetized lab chow dam. The second experiment examined the influence of the type of test dam (35% EDC, 0% EDC, or lab chow) on nipple attachment behavior. Finally, experiment three evaluated the possibility that the data from the preceeding experiments were the result of either testing the offspring in triads or alcohol-induced alterations in maternal behavior. Rat pups from all three groups reared by their biological mothers and a group of 35% EDC offspring fostered at birth to lab chow surrogate mothers were tested alone rather than in triads. The data from all three experiments clearly indicated an age-related pattern of nipple attachment behavior; the latency to attach was shortest in 6- to 12-day-old pups and increased rapidly from 13 to 21 days of age. Prenatal exposure to alcohol significantly increased the latency to attach to the nipple and the rank order of attachment at the younger ages (three to nine days of age) but not in the older animals. Also, the prenatal effect of alcohol was independent of the type of dam to which testing was conducted, the social interaction involved in testing triads, or fostering procedures. These results suggest that prenatal alcohol exposure can interfere with the development of normal suckling behavior, which might influence normal growth. PMID:7157191

  16. Effect of creep feeding system on performance of suckling lambs

    International Nuclear Information System (INIS)

    Twenty seven newly born Barki Lambs of about 3.84 kg live body weight were randomly divided into three groups of nine lambs each. Their weights were recorded at birth. Lambs in the first group were served as controls and fed on their dam's milk only (milk basis) > The second group was fed on their dam's milk in addition to concentrate feed mixture (CFM) as creep feeding> Group three was fed on their dam's milk; concentrate feed mixture and lactic acid producing bacteria. Concentrate feed mixture was offered daily in the morning for lambs under creep feeding system, started at 7 days from birth. Lambs were kept with their mothers in the same pens. Blood samples were collected at 7.30 and 60 days old from the jugular vein of each animal. Total gain, average daily gain and weaning weight of lambs were higher (P<0.05) in groups II and III than control group. Both groups II and III showed no significant difference in weight gain. The higher values serum total proteins were recorded in groups II and III. Values of serum total proteins were recorded in groups II and III . Values of serum albumin were similar in all different groups. However, group III recorded the highest values of globin. Blood serum glutamic pyruvic transaminase (GPT) and glutamic oxalacetic transaminase (GOT) activities were not affected by treatment. It was clearly observed that GPT values were increased with age in all groups. Values for serum glucose were decreased with age until weaning, while serum urea nitrogen was increased with age. The differences among treatments in creatinine concentrations were not significant. Total triiodothyronine (T4) and total thyroxine (T4) concentrations were not significantly different between experimental groups. It is concluded that creep feeding promotes growth in lambs during suckling period and can be successfully used for a short fattening period

    Full Text Available Many factors related to transport to abattoir affects meat quality, but scarce information is available in suckling lambs. Thus, the aim of this work was to evaluate the effects of season and stocking density on carcass and meat quality of suckling lambs during commercial transport to the abattoir. A factorial design (2 × 3 was used: two seasons (winter and summer and three stocking densities (SD; 0.08, 0.12 and 0.20 m2 animal-1. Meat quality variables were measured in the M. longissimus at 24 h post-mortem and after 5 days of refrigerated storage. Lambs transported in summer showed lower liver weight (p<0.001, h* (p<0.05, deoxymyoglobin content (p<0.001, pressed juice (p<0.01, shear force (p<0.001 and firmness (p<0.001, and higher initial pH (p<0.001, L*, b*, C* (p<0.001 and a* (p<0.01, as well as metmyoglobin and oxymyoglobin content (p<0.001, than those transported in winter. The effect of season was dependent on storage time, being colour changes more evident at 24 h than after 5 days of storage, whereas lipid oxidation was only observed in stored meat, which may be explain because the natural antioxidative system decreases with time after slaughter. Scarce effect of SD was found on the carcass and meat quality parameters, thus under our experimental conditions the three SD studied appear to be suitable for suckling lambs transport. However, both carcass and meat quality were within the normal commercial range.

    The radionuclides of most concern with respect to contamination of animals after a nuclear accident are radioiodine, radiocaesium and radiostrontium (ICRP 30, 1979). Of the other significant anthropogenic radionuclides likely to be released in most accidents, only small proportions of that ingested will be absorbed in an animals gut, and the main animal products, milk and meat, will not normally be contaminated to a significant extent. Animal products will mostly be contaminated as a result of ingestion of contaminated feed and possibly, but to a much lesser extent, from inhalation (for radioiodine only). Direct external contamination of animals is of little or no consequence in human food production. Radioiodine and radiostrontium are important with respect to contamination of milk; radiocaesium contaminates both milk and meat. The physical and chemical form of a radionuclide can influence its absorption in the animal gut. For example, following the Chernobyl accident radiocaesium incorporated into vegetation by root uptake was more readily absorbed than that associated with the original deposit. The transfer of radiocaesium and radiostrontium to animals will be presented both as transfer coefficients and aggregated transfer coefficients. For most animal meat products, only radiocaesium is important as other radionuclides do not significantly contaminate muscle. Farm animal products are the most important foodstuff determining radiocaesium intake by the average consumer in the Nordic countries. The major potential source of radioiodine and radiostrontium to humans is milk and milk products. Of the different species, the smaller animals have the highest transfer of radiocaesium from fodder to meat and milk. (EG)

    One hundred and fifty-six Spanish does were used to evaluate the effect of suckling manipulation on postpartum breeding. Does were divided into four herds dependent upon their kidding dates (range from October to January) and location. All kids were nursed ad libitum for approximately 30 days following birth. Groups were then subdivided, and does with kids were randomly allotted to one of the following treatment groups: 1) continuous suckling (CS), 2) once-daily suckling (ODS) or 3) early weaning (EW). Nonlactating does (NL) which lost a kid or aborted were also evaluated for rebreeding performance. At least one fertile male equipped with a marking harness was placed with each treatment group for estrus detection. After 30 days, ODS kids were returned to their dams. The proportion of does exhibiting estrus within 60 days postpartum was greater for ODS and EW does compared to CS does (Pkid production was 1.87 kids/doe/year. These results indicate that reducing the suckling stimulus in Spanish does during the breeding season may result in an earlier return to estrus with a greater percentage of does rebreeding within 60 days postpartum.

  1. Copper absorption from human milk, cow's milk, and infant formulas using a suckling rat model

    International Nuclear Information System (INIS)

    Since copper deficiency is known to occur during infancy, it becomes important to assess copper uptake from various infant diets. The authors have investigated the uptake of copper from human milk, cow's milk, cow's milk formulas, cereal/milk formula and soy formula, compensating for the decay of 64Cu and using the suckling rat as a model. Radiocopper was added to the diet in trace amounts. Ultracentrifugation, ultrafiltration, and gel filtration were used to show that the added 64Cu bound to milk fractions and individual binding compounds in a manner analogous to the distribution of native copper, thus validating the use of extrinsically labeled diets. Labeled diets were intubated into 14-day-old suckling rats. Animals were killed after 6 h and tissues removed and counted. Liver copper uptake was 25% from human milk, 23% from cow's milk formula, 18% from cow's milk, 17% from premature (cow's milk based) infant formula, 17% from cereal/milk formula and 10% from soy formula. These results show that the rat pup model may provide a rapid, inexpensive, and sensitive method to assay bioavailability of copper from infant foods

    Viral myocarditis (VMC) is an inflammation of heart muscle in infants and young adolescents. This study explored the function of halofuginone (HF) in Coxsackievirus B3 (CVB3) -treated suckling mice. HF-treated animal exhibited higher survival rate, lower heart/body weight, and more decreased blood sugar concentration than CVB3 group. HF also reduced the expressions of interleukin(IL)-17 and IL-23 and the numbers of Th17 cells. Moreover, HF downregulated pro-inflammatory cytokine levels and increased anti-inflammatory cytokine levels. The expressions of transforming growth factor(TGF-β1) and nuclear factor kappa-light-chain-enhancer of activated B (NF-κB) p65/ tumor necrosis factor-α (TNF-α) proteins were decreased by HF as well. Finally, the overexpression of TGF-β1 counteracted the protection effect of HF in CVB3-treated suckling mice. In summary, our study suggests HF increases the survival of CVB3 suckling mice, reduces the Th17 cells and pro-inflammatory cytokine levels, and may through downregulation of the TGF-β1-mediated expression of NF-κB p65/TNF-α pathway proteins. These results offer a potential therapeutic strategy for the treatment of VMC. PMID:27021682

    Full Text Available Seventy-seven ewes were randomly divided into groups according to parturition season and suckling mode [Rainy season: continuous (n=14 and controlled (n=13; Dry season: continuous (n=25 and controlled (n=25]. The controlled suckling mode, in both seasons, resulted in a decrease in variables, intervals between parturition and first estrus (reduction of 27.11 and 11.46 days for rainy and dry season, respectively; P<0.05 and between parturition and estrus of conception (reduction of 12.81 and 13.58 days, for rainy and dry season, respectively; P<0.05. As to the lambs, the weight gain was higher in animals subjected to controlled suckling in relation to continuous, especially when lambing occurred in the rainy season (17.83±0.56 vs. 13.95±0.52kg for Lambs' weight at 90 days old, respectively; P<0.05. Therefore, it was concluded that controlled suckling management is better indicated for the Amazonian region, since it allows the ewes to have a shorter puerperium period and the lambs exhibit higher weight gain.

    Full Text Available Abstract Background Diet plays a role on the development of the immune system, and polyunsaturated fatty acids can modulate the expression of a variety of genes. Human milk contains conjugated linoleic acid (CLA, a fatty acid that seems to contribute to immune development. Indeed, recent studies carried out in our group in suckling animals have shown that the immune function is enhanced after feeding them with an 80:20 isomer mix composed of c9,t11 and t10,c12 CLA. However, little work has been done on the effects of CLA on gene expression, and even less regarding immune system development in early life. Results The expression profile of mesenteric lymph nodes from animals supplemented with CLA during gestation and suckling through dam's milk (Group A or by oral gavage (Group B, supplemented just during suckling (Group C and control animals (Group D was determined with the aid of the specific GeneChip® Rat Genome 230 2.0 (Affymettrix. Bioinformatics analyses were performed using the GeneSpring GX software package v10.0.2 and lead to the identification of 89 genes differentially expressed in all three dietary approaches. Generation of a biological association network evidenced several genes, such as connective tissue growth factor (Ctgf, tissue inhibitor of metalloproteinase 1 (Timp1, galanin (Gal, synaptotagmin 1 (Syt1, growth factor receptor bound protein 2 (Grb2, actin gamma 2 (Actg2 and smooth muscle alpha actin (Acta2, as highly interconnected nodes of the resulting network. Gene underexpression was confirmed by Real-Time RT-PCR. Conclusions Ctgf, Timp1, Gal and Syt1, among others, are genes modulated by CLA supplementation that may have a role on mucosal immune responses in early life.

    Localized injections of the mu antagonist CTOP into intracisternal (i.c.) or intracerebroventricular (i.c.v.) sites altered the behavior of 1-day-old rat pups during continuous exposure to an artificial nipple. Blockade of mu opioid receptors by i.c. injection decreased oral responsiveness to the nipple, while blockade of receptors by i.c.v. injection of CTOP increased oral responsiveness. The injection of CTOP into the i.c. site produced a transient reduction in body weight gain in pups suckling from their mother, while injection into the i.c.v. site had no effect. When cesarean-delivered pups were tested prior to suckling, injection of CTOP into the i.c. site increased latency of the first nipple attachment and decreased total time attached to a surrogate nipple providing milk. Injection of CTOP into the i.c.v. site decreased latency to the first nipple attachment. The results indicate that there is a caudal population of opioid receptors that is involved in the initiation of suckling behavior and a rostral population that plays a role in decreasing responsiveness at the nipple.

    Background Diet plays a role on the development of the immune system, and polyunsaturated fatty acids can modulate the expression of a variety of genes. Human milk contains conjugated linoleic acid (CLA), a fatty acid that seems to contribute to immune development. Indeed, recent studies carried out in our group in suckling animals have shown that the immune function is enhanced after feeding them with an 80:20 isomer mix composed of c9,t11 and t10,c12 CLA. However, little work has been done ...

    Full Text Available The quantities and distribution patterns of serotonin-immunoreactive (serotonin-IR enterochromaffin cells (EC were studied immunohistochemically in the small intestine of suckling piglets stimulated with red kidney bean lectin, and in nonstimulated, control animals. The co-expression patterns of serotonin with somatostatin (SOM or corticotropin releasing-factor (CRF were also studied. After the lectin treatment, the increased numbers of EC were noted in the duodenum of experimental animals. Lectin stimulation did not change the proportions of EC in the jejunum and ileum. In the duodenal epithelium of the lectin-stimulated piglets, the vast majority of serotonin-IR EC were distributed at the basis of crypts. After the lectin administration, the proportions of serotonin-IR/SOM-IR EC were statistically similar in all sections of the small intestine. No upregulation of CRF was found in duodenal, jejunal, and ileal EC of lectin-treated animals. The findings demonstrated that red kidney bean lectin increased the serotonin reservoir in the duodenum, and thus may be an effective stimulant of the gut maturation in suckling mammals.

  10. Influence Of Summer Season On Some Biochemical And Hormonal Changes In Crossbred Cows During Suckling Period

    International Nuclear Information System (INIS)

    According to the seasonal variations in environmental conditions in post-partum cows, some biochemical and physiological changes which affect the productive efficiency of farm animals may occur. This study was conducted in the bovine farm of Experimental Farms Project of Nuclear Research Centre, Atomic Energy Authority, Inshas, Egypt, to evaluate some blood biochemical and some hormonal changes during the suckling period in crossbred cows under winter and summer conditions. Alterations in metabolites and metabolic hormones during the first 10 weeks post-partum in both winter and summer during a period of suckling were analyzed on a total of 13 crossbred (Brown Swiss X Balady) cows (winter, n=7; summer, n=6). The blood samples were taken at 2 weeks intervals, 5 times in each season to determine the concentrations and changes in glucose, urea, total cholesterol, total proteins and some hormones including leptin, T4 and progesterone (P4) under winter and summer conditions. The data indicated that total protein (P<0.01), glucose (P<0.05), leptin (P<0.01), total cholesterol (P<0.01), and T4 (P<0.01) had significant seasonal differences between the two calving groups. A positive correlation coefficient was observed between leptin and T4 hormone. From the obtained data, it could be concluded that in summer season, certain biochemical and hormonal levels of calving cows may enhanced but not enough to affect the levels of urea and progesterone. The positive correlation between leptin and T4 may indicate association in the rate of metabolism.

  11. Fate of milk calcium in the gastrointestinal tract of suckling rats

    International Nuclear Information System (INIS)

    In the rat, as in many other mammals, the majority of milk Ca is associated with casein micelles. Because luminal proteolysis is immature in the suckling rat, we investigated the hypothesis that milk Ca remains in the macromolecular form as it traverses the stomach and upper small intestine. When intestinal contents of rat pups were examined 1 h after gavage with 45Ca-milk, 98% of the 45Ca was found to be in a soluble form. Surprisingly, chromatography on Sephadex G-10 showed it to have a molecular weight in the range of that of Ca2+. Analysis of gastric contents showed the stomach to be the initial site of release of Ca from the casein micelles. Although only 45% of the 45Ca was in a soluble form in stomach contents, 100% of this soluble 45Ca behaved as Ca2+. Comparison with the fate of 32P from milk confirmed the suggestion that most of the Ca is released as Ca2+. In vitro studies suggested that this release is the result of simple dilution or the combined action of intrinsic milk enzymes and dilution. Because milk Ca appears to enter the small intestine as Ca2+, we presume its mechanism of absorption in suckling animals is the same as that already established using simple salts of Ca. Nevertheless, the slow release from the bound form may be important in establishing the physiological pattern of Ca absorption in the infant. Implications of this for the supplementation of milks for low-birth-weight human infants is discussed

    Full Text Available The objective of the present research was to determine the contents of fat, cholesterol and fatty acids of eight beef cuts from unsupplemented, suckling, 7-8 month old male and female calves reared on permanent pastures in the VIIth Region of Chile by small cattle producers. A total of 54 animals with a mean carcass weight of 150 ± 22 kg were slaughtered in a commercial abattoir on three different dates during the month of March, 2008. Five samples of each of eight cuts were collected at random as they exited the abattoir, cooled and packed following industry practices. Beef cuts were selected based on an earlier, unreplicated analysis of 21 common cuts, to represent a wide range of cuts currently available to consumers. Large and significant differences were observed in fat content with a mean of 2.12%, ranging between 4.23% for sirloin strip and 0.68% for butcher’s roast. The cholesterol content did not differ between cuts (mean 44.7 mg/100 mg meat and was unrelated to fat percentage. A stringent discriminant analysis of the fatty acid profiles detected highly significant differences between cuts and correctly classified 37 of the 40 samples. The n6:n3 ratio did not differ between cuts and ranged between 1.9 for sirloin strip and 2.6 for rib roast and silverside’s end. Significant differences between cuts were detected for most fatty acids, and for the atherogenicity index. Nevertheless, the latter only varied between 0.60 and 1.07 for topside and sirloin strip respectively. The results are compared with literature values. Notwithstanding differences between cuts, all beef samples were lean and had lipid profiles compatible with human health as part of a balanced diet.El objetivo del trabajo fue determinar el contenido de grasa, colesterol y perfil de ácidos grasos de ocho cortes provenientes de terneros lactantes, de 7-8 meses de edad y engordados en prados permanentes de la VII Region de Chile, por productores pequeños.

    Amino acids, ammonia, urea, orotate, and nitrate plus nitrite (stable oxidation products of nitric oxide) were determined in plasma of 1- to 21-d-old suckling pigs. Jugular venous blood samples were obtained from pigs at 1, 3, 7, 14, and 21 d of age for analysis of plasma amino acids and metabolites by HPLC and enzymatic methods. Plasma concentrations of arginine and its immediate precursors (citrulline and ornithine) decreased (P Plasma concentrations of glutamine declined (P Plasma concentrations of branched-chain amino acids, threonine, and alanine decreased (P changes (P > 0.05) in plasma concentrations of other amino acids. Plasma concentrations of ammonia increased (P nitric oxide synthesis, our results of the decreased plasma concentrations of arginine and nitrate plus nitrite, as well as the increased plasma ammonia concentration, indicate a hitherto unrecognized deficiency of arginine in 7- to 21-d-old suckling pigs. Arginine is an essential amino acid for piglets and has a great potential to enhance neonatal growth; therefore, further studies are necessary to elucidate the mechanism responsible for arginine deficiency in sow-reared piglets and to identify hormonal and metabolic means for improving neonatal arginine nutrition and growth.

    The present study was undertaken to evaluate the oxidative damage, biochemical and histopathological alterations in sucking rats whose mothers were exposed to the insecticide chlorpyrifos (CPF). Dams were administered CPF, via oral route. Doses equalled 0.01 mg kg(-1) body weight (b.wt.; acceptable daily intake, ADI), 1.00 mg kg(-1) b.wt. (no observed adverse effects level, NOAEL) and 1.35 mg kg(-1) b.wt. (1/100 lethal dose [LD(50)]) from postnatal day 1 until day 20 after delivery. At two high doses of CPF, the body weight gain and relative liver and kidney weight of suckling pups were significantly decreased. Exposure of the mothers to CPF caused increase in lipid peroxidation (LPO) and decrease in superoxide dismutase (SOD) and glutathione-s-transferase (GST) in lactating pups. CPF altered the level of the marker parameters related to the liver and kidneys. Consistent histological changes were found in the liver and kidneys of the subjected pups, especially at the higher doses. The results suggested that the transfer of CPF intoxication through the mother's milk has resulted in oxidative stress and biochemical and histopathological alterations in the suckling pups. The data of this study may be considered as a contribution to the problem of lactational transfer of the relatively less persistent OP pesticides, such as CPF. PMID:20028704

    Full Text Available Abstract Background Previous studies have shown that in male rats, exposure to maternal protein restriction either in utero or whilst suckling can have profound effects on both longevity and kidney telomere lengths. This study monitored albuminuria longitudinally in male rats whose mothers had been protein restricted either during pregnancy or lactation. Methods Pregnant Wistar rats were fed either a 20% ('control' or an 8% protein ('low protein' diet. At two days of age some of the pups were cross-fostered to dams fed the diet that was not given to their biological mothers. At weaning all pups were fed standard chow. Urine samples were collected for the measurement of albumin and creatinine at monthly intervals from two months-of-age. Longitudinal analysis was then performed using repeated measures analysis of variance. Results Overall estimated marginal geometric mean (95 % confidence interval urine albumin to creatinine ratios were: control animals 79.5 (57.2~110.6 g/mol (n = 6 litters, 24 animals in total, those exposed in utero to maternal protein restriction 71.0 (47.4~106.5 (n = 4 litters, 16 animals in total, those exposed to maternal protein restriction whilst suckling 21.2 (14.7~30.4 (n = 5 litters, 20 animals in total (p Conclusion Animals exposed to maternal protein restriction whilst suckling exhibited lower urine albumin excretions during much of adult life. As urine albumin can be nephrotoxic, these rats therefore appeared to be relatively protected against future nephron damage like that previously observed in animals exposed to maternal protein restriction in utero.

    2015-01-01

    Full Text Available The active substance of Suilectin™ is a mixture of five phytohaemagglutinin (PHA isoforms. The Panel on Additives and Products or Substances used in Animal Feed (FEEDAP considers that the haemagglutination activity (measured by haemagglutinating units (HAUs does not reflect the biological activity of the additive in a comprehensive way. The additive is intended only for aqueous suspension in water for drinking or in liquid complementary feed for suckling piglets. The FEEDAP Panel concludes that the additive is safe for suckling piglets when used under the proposed conditions of use of 220 HAU/piglet for three days. The Panel also considers that there are no reasons to expect that the dose of 660 HAU/piglet in a single administration would not be safe. The use of Suilectin in accordance with the conditions of use proposed by the applicant is considered to be of no concern for the health of the consumer. Suilectin is not an irritant to skin or eyes and is not a skin sensitiser. However, considering its physical and toxicological properties, there is a potential hazard by inhalation exposure. Considering that PHAs are immunogenic substances, the additive should be considered to be a respiratory sensitiser. The additive is a natural plant substance and its use will not result in a substantial increase in concentration in the environment. Therefore there are no safety concerns for the environment. The FEEDAP Panel cannot conclude on the efficacy of the additive in suckling piglets.

  17. Impact of iron status on cadmium uptake in suckling piglets

    International Nuclear Information System (INIS)

    Low iron status is known to increase the uptake of dietary cadmium in both adolescents and adults and there are indications that cadmium is absorbed from the intestine by the two major iron transporters divalent metal transporter 1 (DMT1) and ferroportin 1 (FPN1). In addition, it has been suggested that duodenal metallothionein (MT) may limit the transport of cadmium across the intestinal epithelium. The present investigation was undertaken to examine whether iron status influences cadmium absorption in newborns by applying a model of suckling piglets and the possible roles of duodenal DMT1, FPN1 and MT. An oral cadmium dose (20 μg/kg body weight) was given daily for 6 consecutive days on postnatal days (PNDs) 10-15 to iron-deficient or iron-supplemented piglets. The cadmium dose was chosen to keep the cadmium level at a realistically low but still detectable level, and without inducing any adverse health effects in the piglets. As indicators of cadmium uptake, cadmium levels in blood and kidneys were measured on PND 16 by inductively coupled plasma-mass spectrometry (ICP-MS). Cadmium levels in blood were statistically significantly correlated with cadmium levels in kidneys. The cadmium uptake was not higher in iron-deficient suckling piglets; rather, we detected a higher cadmium uptake in the iron-supplemented ones. The expression and localisation of DMT1, FPN1 and MT were not affected by iron status and could therefore not explain the findings. Our results suggest that there are developmental differences in the handling of both iron and cadmium in newborns as compared to adults

    In recent years, there has been an increasing interest on donkey milk production, on its characteristics, and also on breeding techniques. Donkey milk is characterized by high economic value, although the productive level of jennies is poor. During the milking process, foals are usually separated from their dams, allowing the milk collection in the mammary gland of jennies before milking session. This takes 8 h per day of fastening period for lactating donkey foals. During this period, it could be possible to apply a partial artificial suckling system (artificial suckling during daytime and natural suckling during the night). The aim of the work is the evaluation of the effect of this innovative technique on in vivo performances and on meat production traits of Martina Franca donkey foals. Forty Martina Franca jennies with their foals were used for the trial. After colostrum assumption, 20 foals were partially artificially suckled (AS) during each day, and 20 foals were naturally suckled (NS). From 8.00 to 20.00, both groups were separated from their mothers in order to allow the milking procedures of the jennies. The AS group was in a stall equipped with an automatic calf-suckling machine. For each group, 10 foals were slaughtered at 12 months and 10 foals at 18 months. Artificial suckling system positively affected the growth rate of donkey foals, particularly in the first 6 months from birth, with higher weekly weight gain (P effects were observed on carcass dressing percentage (P > 0.05). Artificial suckling system permitted to extend the time of foal separation from their mothers increasing milk collection time per day, awarding fastening periods in foals. PMID:26510946

    Full Text Available The principal physiological role of vitamin D in all vertebrates is in calcium and phosphorus homeostasis. The classic clinical deficiency syndrome is rickets. The FEEDAP Panel notes that for turkeys for fattening, equines, bovines, ovines and pigs the maximum content for vitamin D3 in feed does not provide any margin of safety, and that, except for pigs, the maximum content is above the upper safe level, according to National Research Council data when animals were fed a supplemented diet for more than 60 days. No safety concern was identified for the use of vitamin D3 in chickens for fattening and fish. Not withstanding the long history of supplementing compound feed with vitamin D and the absence of publicly reported intolerances, the FEEDAP Panel is not in a position to draw final conclusions on the safety of vitamin D and considers the current maximum contents as temporarily acceptable. Any additional administration of vitamin D3 via water for drinking represents a safety concern. Current nutritional surveys in 14 European countries showed that vitamin D intake is sufficiently below the upper safe limit. The FEEDAP Panel assumes that foodstuffs of animal origin were produced following current production practices, including vitamin D3 supplementation of feed and concludes that the use of vitamin D in animal nutrition at the currently authorised maximum dietary content has not and will not cause the tolerable upper intake level to be exceeded. Vitamin D3 is not an irritant to skin and eyes and is not a skin sensitiser. Inhaled vitamin D3 is highly toxic; exposure to dust is harmful to persons handling the additive. No risk to the environment resulting from the use of vitamin D3 in animal nutrition is expected. The vitamin D3 under application is regarded as an effective dietary source of the vitamin in animal nutrition.

  20. Immunization with cholera toxin B subunit induces high-level protection in the suckling mouse model of cholera.

    Directory of Open Access Journals (Sweden)

    Gregory A Price

    Full Text Available Cholera toxin (CT is the primary virulence factor responsible for severe cholera. Vibrio cholerae strains unable to produce CT show severe attenuation of virulence in animals and humans. The pentameric B subunit of CT (CTB contains the immunodominant epitopes recognized by antibodies that neutralize CT. Although CTB is a potent immunogen and a promising protective vaccine antigen in animal models, immunization of humans with detoxified CT failed to protect against cholera. We recently demonstrated however that pups reared from mice immunized intraperitoneally (IP with 3 doses of recombinant CTB were well protected against a highly lethal challenge dose of V. cholerae N16961. The present study investigated how the route and number of immunizations with CTB could influence protective efficacy in the suckling mouse model of cholera. To this end female mice were immunized with CTB intranasally (IN, IP, and subcutaneously (SC. Serum and fecal extracts were analyzed for anti-CTB antibodies by quantitative ELISA, and pups born to immunized mothers were challenged orogastrically with a lethal dose of V. cholerae. Pups from all immunized groups were highly protected from death by 48 hours (64-100% survival. Cox regression showed that percent body weight loss at 24 hours predicted death by 48 hours, but we were unable to validate a specific amount of weight loss as a surrogate marker for protection. Although CTB was highly protective in all regimens, three parenteral immunizations showed trends toward higher survival and less weight loss at 24 hours post infection. These results demonstrate that immunization with CTB by any of several routes and dosing regimens can provide protection against live V. cholerae challenge in the suckling mouse model of cholera. Our data extend the results of previous studies and provide additional support for the inclusion of CTB in the development of a subunit vaccine against V. cholerae.

    Full Text Available Abstract Background Suckling can be a peaceful or vulnerable event for goats and kids, whereas, separation is suggested as stressful. The aim of this study was to investigate physiology and behaviour in these two different situations in dairy goats. Methods Four studies were performed with seven goats kept with their first-born kid in individual boxes. The goats were videotaped and heart rate and arterial blood pressure were recorded every minute by telemetry from parturition until 24 hours after separation. One to two days after parturition, Study 1 was performed with analyses of heart rate and blood pressure around a suckling. In Study 2, performed 3-5 days after parturition, blood sampling was done before, during and after suckling. Study 3 was performed 4-6 days post partum, with blood sampling before and after a permanent goat and kid separation. In addition, vocalisations were recorded after separation. Blood samples were obtained from a jugular vein catheter and analysed for plasma cortisol, β-endorphin, oxytocin, and vasopressin concentrations. Study 4 was performed during the first (N1 and second nights (N2 after parturition and the nights after Study 2 (N3 and 3 (N4. Heart rate, blood pressure and time spent lying down were recorded. Results The kids suckled 2 ± 0.2 times per hour and each suckling bout lasted 43 ± 15 s. In Study 1, heart rate and blood pressure did not change significantly during undisturbed suckling. In Study 2, plasma cortisol (P ≤ 0.05 during suckling and P ≤ 0.01 five minutes after suckling and β-endorphin (P ≤ 0.05 concentrations increased during suckling, but oxytocin and vasopressin concentrations did not change. In Study 3, the goats and kids vocalised intensively during the first 20 minutes after separation, but the physiological variables were not affected.

    Full Text Available Fatty acid profiles are a major contributor to meat quality in small ruminants. Nevertheless, while fatty acid profiles from suckling lambs have been extensively studied they are virtually unknown in suckling kids. Fatty acid profiles of intramuscular and kidney knob fat depots of suckling kids were compared with fatty acid profiles of lambs with a quality label in the Spanish market. Forty suckling kids from Blanca Celtibérica (BC, Moncaína (Mo, Negra Serrana (NS and Murciano Granadina (MG breeds and 20 Churra male suckling lambs labelled with ‘Lechazo de Castilla y León’ Protected Geographic Indication were slaughtered at commercial live weights (12 kg. In both depots differences in the unsaturated fatty acid profile were observed between breeds. The most pronounced differences were observed between meat goat breeds (BC, Mo and NS and lambs, whilst a greater similarity in the fatty acid profile was observed between kids from dairy goat breeds (MG and lambs. The lowest polyunsaturated fatty acid content was observed in meat goat breeds (approximately 21 to 22% of total fatty acids detected in the intramuscular fat. No significant differences in atherogenic index and desirable fatty acid content (range 68 to 70% of total fatty acids detected were observed. However, a more favourable (lower than 8.07 n-6/n-3 ratio was observed in meat goat breeds. The use of fatty acid profiles from intramuscular and kidney knob fat could be proposed as a tool to differentiate goat kids and lambs. The fact that intramuscular fat from suckling kids and lambs shows appropriate lipid nutritional indices and their low carcass fatness indicate that moderate consumption of suckling kid and lamb meat may contribute to an overall balanced diet for humans.

  5. Linking suckling biomechanics to the development of the palate

    Skulls are amongst the most informative documents of evolutionary history but a complex geometry, coupled with composite material properties and complicated biomechanics, have made it particularly challenging to identify mechanical principles guiding the skull’s morphogenesis. Despite this challenge, multiple lines of evidence, for example the relationship between masticatory function and the evolution of jaw shape, nonetheless suggest that mechanobiology plays a major role in skull morphogenesis. To begin to tackle this persistent challenge, cellular, molecular and tissue-level analyses of the developing mouse palate were coupled with finite element modeling to demonstrate that patterns of strain created by mammalian-specific oral behaviors produce complementary patterns of chondrogenic gene expression in an initially homogeneous population of cranial neural crest cells. Neural crest cells change from an osteogenic to a chondrogenic fate, leading to the materialization of cartilaginous growth plate-like structures in the palatal midline. These growth plates contribute to lateral expansion of the head but are transient structures; when the strain patterns associated with suckling dissipate at weaning, the growth plates disappear and the palate ossifies. Thus, mechanical cues such as strain appear to co-regulate cell fate specification and ultimately, help drive large-scale morphogenetic changes in head shape.

  6. Tb-160 metabolism in the rat during lactation and suckling

    International Nuclear Information System (INIS)

    Terbium metabolism in the rat during lactation and suckling was studied. The study comprised 160 female Wistar rats with 160TbCl3 administered i.v. during various periods of lactation and their offspring. The largest amounts of Tb-160 were found in the liver (2,5% of the administered dose per gram of the organ) and bones (1,1% per gram) of female rats. The peak terbium uptake was found in the milk gland (2,1% of the dose) 2 hours after the i.v. administration. The uptakes in infants increased with age. No significant differences were observed in the specific activity of terbium in the stomach, large and small intestines of infants 1-21 days old. Biological half-lives for the stomach, small and large intestines were 0,60 ± 0,11, 1,89 ± 0,95 and 3,65 ± 0,12 days. 27 refs., 3 tabs. (author)

    Full Text Available The effects of suckling and remating interval (11 or 21 d post partum were studied in primiparous (P=25 and multiparous (M=23 hybrid rabbits. In P rabbits, suckling had no signifi- cant effect on mating incidence; however, a higher percentage of females accepted the male on d 11 than on d 21 (P<0.01. In M rabbits, no significant differences in mating performance due to either day, suckling or their interaction were found. A higher proportion of nonsuckled than suckled P rab- bits ovulated (P<0.01. Ovulation incidence was not affected significantly by day of mating, suckling or their interaction in M rabbits. A comparison of the day influence in P and M rabbits on mating incidence showed a greater effect in the P (P<0.05 while the suckling effect on ovulation perform- ance showed an insignificant difference in the two parity groups. Ovulation rate, as assessed by ultrasound, was not influenced significantly by day or suckling in either P or M rabbits. The follicle distribution was marked by fewer large follicles and lower plasma estrogen levels were detected in suckled than in nonsuckled P and M rabbits (P<0.05. Further research is needed to elucidate these phenomena also when AI is performed.

    Methylmercury (MeHg) is a highly neurotoxic compound and several studies have reported intoxication signs in children whose mothers were exposed to this environmental toxicant. Although it is well established that the in utero exposure to MeHg causes neurological deficits in animals and humans, there is no evidence of the exclusive contribution of lactational exposure to MeHg as a possible cause of neurotoxicity in the offspring. In this study, we investigated the exclusive contribution of MeHg exposure through maternal milk on biochemical parameters related to the glutamatergic homeostasis (glutamate uptake by slices) and to the oxidative stress (total and nonprotein sulfhydryl groups, nonprotein hydroperoxides, glutathione peroxidase and catalase activities) in the cerebellum of suckling mice (Swiss albino). The same parameters were also evaluated in the cerebellum of mothers. Our results showed, for the first time, that lactational exposure to MeHg caused a high percent of inhibition (50%) on glutamate uptake by cerebellar slices in pups. Contrarily, this effect was not observed in mothers, which were submitted to a direct oral exposure to MeHg (15 mg/l in drinking water). In addition, behavioral/functional changes were observed in the weaning mice exposed to MeHg. It was observed an increase in the levels of nonprotein hydroperoxides in cerebellum, and this increase was negatively correlated to the glutamate uptake by cerebellar slices. This study indicates that (1) the exposure of lactating mice to MeHg causes inhibition of the glutamate uptake by cerebellar slices in the offspring; (2) this inhibitory effect seems to be related to increased levels of hydroperoxide.

    Full Text Available Rabies virus is a kind of virus having strict neurotropic property. Intracerebral inoculation method was commonly used to RV-related research. SRV9 is an attenuated RV vaccine strain. In the present study, we inoculated intracerebrally on suckling mouse with SRV9 strain. The results showed that SRV9 could cause a mortality rate of 100% on suckling mice below 13 day old. The mortality rates of 14-17 day old mice were 68, 33, 33 and 17%, respectively without incidence above 18 day old. Meanwhile, the results showed that the growth of survival suckling mice was inhibited remarkably after intracerebral inoculation SRV9. The 16 day old survival suckling mice were chosen to perform body weight test and the result showed that the weight growth was very slow with 14% less than normal growth rate. However, 2 weeks latter the weight of the mice began to recover gradually but slowly. It was suggested that the intracerebral RV reproduction could take a significant effect on the growth and development of the mice and with RV being eliminated by antibody, the weight of the mice which were inoculated with SRV9 could gradually recover.

    This study aimed to investigate the effects of dietary fibre sources on the gut microbiota in suckling piglets, and to test the hypothesis that a moderate increase of dietary fibre may affect the gut microbiota during the suckling period. Suckling piglets were fed different fibre-containing diets or a control diet from postnatal day 7 to 22. Digesta samples from cecum, proximal colon and distal colon were used for Pig Intestinal Tract Chip analysis. The data showed that the effects of fibre-containing diet on the gut microbiota differed in the fibre source and gut location. The alfalfa diet increased Clostridium cluster XIVb and Sporobacter termitidis in the cecum compared to the pure cellulose diet. Compared to the control diet, the alfalfa diet also increased Coprococcus eutactus in the distal colon, while the pure cellulose diet decreased Eubacterium pyruvativorans in the cecum. The pure cellulose diet increased Prevotella ruminicola compared to the wheat bran diet. Interestingly, the alfalfa group had the lowest abundance of the potential pathogen Streptococcus suis in the cecum and distal colon. These results indicated that a moderate increase in dietary fibres affected the microbial composition in suckling piglets, and that the alfalfa inclusion produced some beneficial effects on the microbial communities.

  14. Thyroid function in post-weaning rats whose dams were fed a low-protein diet during suckling

    1997-01-01

    Full Text Available This study was designed to evaluate the thyroid and pituitary hormone levels in post-weaning rats whose dams were fed a low-protein diet during suckling (21 days. The dams and pups were divided into 2 groups: a control group fed a diet containing 22% protein that supplies the necessary amount of protein for the rat and is the usual content of protein in most commercial rat chow, and a diet group fed a low-protein (8% diet in which the protein was substituted by an isocaloric amount of starch. After weaning all dams and pups received the 22% protein diet. Two hours before sacrifice of pups aged 21, 30 and 60 days, a tracer dose (0.6 µCi of 125I was injected (ip into each animal. Blood and thyroid glands of pups were collected for the determination of serum T4, T3 and TSH and radioiodine uptake. Low protein diet caused a slight decrease in radioiodine uptake at 21 days, and a significant decrease in T3 levels (128 ± 14 vs 74 ± 9 ng/dl, P<0.05, while T4 levels did not change and TSH was increased slightly. At 30 days, T3 and TSH did not change while there was a significant increase in both T4 levels (4.8 ± 0.3 vs 6.1 ± 0.2 µg/dl, P<0.05 and in radioiodine uptake levels (0.34 ± 0.02 vs 0.50 ± 0.03%/mg thyroid, P<0.05. At 60 days serum T3, T4 and TSH levels were normal, but radioiodine uptake was still significantly increased (0.33 ± 0.02 vs 0.41 ± 0.03%/mg thyroid, P<0.05. Thus, it seems that protein malnutrition of the dams during suckling causes hypothyroidism in the pups at 21 days that has a compensatory mechanism increasing thyroid function after refeeding with a 22% protein diet. The radioiodine uptake still remained altered at 60 days, when all the hormonal serum levels returned to the normal values, suggesting a permanent change in the thyroid function

    The activities of various glycosidases in homogenates of the small intestinal mucosa of two adult and 18 suckling tammar wallabies (M. eugenii) aged from 6 to 50 weeks were investigated. Lactase (beta-D-galactosidase), beta-N-acetylglucosaminidase, alpha-L-fucosidase and neuraminidase activities were high during the first 34 weeks post partum and then declined to very low levels. Maltase, isomaltase, sucrase and trehalase activities were very low or absent during the first 34 weeks, and then increased. The lactase activity was unusual in being greater in the distal than the middle or proximal thirds of the intestine, and in its low pH optimum (pH 4.6), inhibition by p-chloromercuribenzene sulfonate but not by Tris, and lack of cellobiase activity. These properties are those of a lysosomal acid beta-galactosidase rather than of a brush border neutral lactase. The maltase activity had the characteristics of a lysosomal acid alpha-glucosidase early in lactation and of a brush border neutral maltase in adult animals. The significance of these findings is discussed in relation to changes in dietary carbohydrates during weaning and to the mode of digestion of milk carbohydrates by the pouch young. PMID:6783021

Thirty two suckling lambs, sixteen male and sixteen female, were distributed into 4 diets with different concentrations of crude glycerin: 0, 10, 20 and 30% crude glycerin, in the replacement of corn, in the isoproteic supplement (18% CP provided daily in amounts equivalent to 2% of body weight. The experimental design was randomized blocks, with each variable data submitted to analysis of variance at 5% significance and the significant results subjected to regression analysis. There was no effect (P>0,05 of contents of crude glycerin on the chemical composition and cholesterol content of lamb meat. On the other hand, there was increased linearly (P>0,05 pH and cooking losses by the use of crude glycerin. No influence (P>0,05 of crude glycerin concentration on the texture profile analysis (TPA, sensorial analysis by triangular test and even when was evaluated attributes color, tenderness and juiciness of lamb meat. Up to 30% of crude glycerin in the supplement provided in creep feeding for suckling lambs grazing ryegrass do not compromise the physical-chemical and sensorial quality of the lamb meat.

    In postparturient goats, olfactory recognition of the young allows the establishment of a selective bond between the mother and her kids. Once this bond is formed, the mother rejects alien young that attempt to suckle. We tested whether the development of the maternal selective bond in goats modulates prolactin (PRL) and oxytocin (OT) release in response to suckling. On day 37 of lactation, serial blood samples were taken during nursing of the mother's own or alien kid(s) in 10 intact/selective goats and in 10 goats rendered anosmic/nonselective through prepartum peripheral ZnSO(4) irrigation. Spontaneous nursing behavior was also studied weekly from day 7 to 30 of lactation, at which time milk production was measured. Maternal selectivity had no effect on PRL release, in contrast to OT release, which was significantly affected by this factor. Intact mothers released OT only when nursing their own kids, but not with aliens, while anosmic/nonselective dams showed an increase in OT levels regardless of the identity of the kids. In addition to these effects on maternal selectivity, the amplitude of the response of both hormones was lower in anosmic mothers than in intact mothers. Finally, nursing behavior and milk production were not significantly affected by anosmia. We conclude that maternal selective behavior in goats, which relies on the individual olfactory signature of the kid, modulates the OT, but not the PRL, response to suckling. In addition, perception of the smell of the young appears to have a general facilitatory effect, independent of the kid's identity, on the release of both hormones. PMID:12367576

  3. Hepatic adaptation compensates inactivation of intestinal arginine biosynthesis in suckling mice.

    Full Text Available Suckling mammals, including mice, differ from adults in the abundant expression of enzymes that synthesize arginine from citrulline in their enterocytes. To investigate the importance of the small-intestinal arginine synthesis for whole-body arginine production in suckling mice, we floxed exon 13 of the argininosuccinate synthetase (Ass gene, which codes for a key enzyme in arginine biosynthesis, and specifically and completely ablated Ass in enterocytes by crossing Ass (fl and Villin-Cre mice. Unexpectedly, Ass (fl/fl /VilCre (tg/- mice showed no developmental impairments. Amino-acid fluxes across the intestine, liver, and kidneys were calculated after determining the blood flow in the portal vein, and hepatic and renal arteries (86%, 14%, and 33%, respectively, of the transhepatic blood flow in 14-day-old mice. Relative to control mice, citrulline production in the splanchnic region of Ass (fl/fl /VilCre (tg/- mice doubled, while arginine production was abolished. Furthermore, the net production of arginine and most other amino acids in the liver of suckling control mice declined to naught or even changed to consumption in Ass (fl/fl /VilCre (tg/- mice, and had, thus, become remarkably similar to that of post-weaning wild-type mice, which no longer express arginine-biosynthesizing enzymes in their small intestine. The adaptive changes in liver function were accompanied by an increased expression of genes involved in arginine metabolism (Asl, Got1, Gpt2, Glud1, Arg1, and Arg2 and transport (Slc25a13, Slc25a15, and Slc3a2, whereas no such changes were found in the intestine. Our findings suggest that the genetic premature deletion of arginine synthesis in enterocytes causes a premature induction of the post-weaning pattern of amino-acid metabolism in the liver.

    Full Text Available In recent years interest has grown in the zootechnical exploitation of environmental feeding resources, above all in marginal areas. The survival of these areas is linked to the development of the limited available resources. Of these, natural pastures represent one of the most important, not only because their zootechnical utilisation permits savings in alimentary costs, but above all because it results in better quality dairy and meat products. The aim of this study is to verify if and to what level ewe feeding systems influence the meat quality of suckling lambs.

  11. Distribution of lead in lactating mice and suckling offspring with special emphasis on the mammary gland

    International Nuclear Information System (INIS)

    The distribution of lead in lactating mice and suckling offspring was studied with whole body autoradiography at 4 and 24 h after a single intravenous injection of 203Pb (50 mmol Pb/kg) to the dams. In the lactating mice on day 14 of lactation, the highest uptake of radioactivity at 4 h after administration was recorded in renal cortex, skeleton and liver. A high uptake was also evident in the mannary gland. At 24 h after administration, the radioactivity had decreased in most organs except in the skeleton. In the suckling pups, exposed to lead only via dams' milk for 24 h, the highest level of radioactivity was present in the intestinal mucosa and a much lower level of radioactivity was present in the skeleton. The mammary glands from mice given three daily intravenous injections of 240 μmol Pb/kg were examined with X-ray microanalysis. At 4 h after the last injection, lead was found associated with casein micelles both inside the alveolar cell and in the milk lumen, indicating that lead is excreted into the milk, bound to casein, via the Golgi secretory system.

  13. Transplacental passage of 26Al from pregnant rats to fetuses and 26Al transfer through maternal milk to suckling rats

    International Nuclear Information System (INIS)

    Aluminium (Al) is toxic to the growth of fetuses and sucklings. However, the incorporation of Al into fetuses and sucklings in the periods of gestation and lactation has not been well clarified because Al lacks a suitable isotope for a tracer experiment. In this study, we used 26Al (a radioisotope of Al with half-life of 716,000 yr) as a tracer, and measured 26Al incorporation into fetuses and sucklings by accelerator mass spectrometry (AMS). To investigate Al incorporation into fetuses through transplacental passage, 26Al (26AlCl3) was subcutaneously injected into pregnant rats on day 15 of gestation. 26Al was also subcutaneoulsy injected into lactating rats from day 1 to day 20 postpartum. By day 20 of gestation, 0.2% of the 26Al injected into a pregnant rat had been transferred to the fetuses, and 26Al was detected in the brain and liver of the fetuses. On day 9 postpartum, high levels of 26Al were demonstrated in the brain, liver, kidneys and blood of suckling rats. It is concluded that 26Al subcutaneously injected into pregnant rats and/or lactating rats is incorporated into their offspring through transplacental passage and/or maternal milk

  14. Roles of outer capsid proteins as determinants of pathogenicity and host range restriction of avian rotaviruses in a suckling mouse model

    International Nuclear Information System (INIS)

    We previously demonstrated that a pigeon rotavirus, PO-13, but not turkey strains Ty-3 and Ty-1 and a chicken strain, Ch-1, induced diarrhea in heterologous suckling mice. In this study, it was suggested that these avirulent strains, but not PO-13, were inactivated immediately in gastrointestinal tracts of suckling mice when they were orally inoculated. To determine which viral proteins contribute to the differences between the pathogenicitiy and the inactivation of PO-13 and Ty-3 in suckling mice, six PO-13 x Ty-3 reassortant strains that had the genes of the outer capsid proteins, VP4 and VP7, derived from the opposite strain were prepared and were orally inoculated to suckling mice. A single strain that had both PO-13 VP4 and VP7 with the genetic background of Ty-3 had an intermediate virulence for suckling mice. Three strains with Ty-3 VP7, regardless of the origin of VP4, rapidly disappeared from gastrointestinal tracts of suckling mice. These results indicated that the difference between the pathogenicity of PO-13 and that of Ty-3 was mainly dependent on both their VP4 and VP7. In particular, VP7 was found to be related to the inactivation of Ty-3 in gastrointestinal tracts of suckling mice

    Full Text Available Purpose/Objective: To assess the correct position, attachment and effective suckling in the breastfeeding of infants as practiced by mothers attending hospitals at Benghazi. Materials and Methods : An observational, descriptive, cross-sectional study was done at AlJamahiriya and AlFateh Hospital in Benghazi, Libya, from November 2009 to February 2010. One hundred ninety-two mother-neonate units were observed for mother′s and baby′s position, attachment and effective suckling using WHO B-R-E-A-S-T- Feed observation form. Grading of positioning, attachment and suckling was done according to the score of various characteristics. Data thus collected were analyzed using software SPSS 11.5 version. Results: About 15% of the infants were about a week old (early neonatal period and 85% were in the late neonatal period. There was poorer positioning among primipara (24.0% than multipara (8.9-12.5%mothers. Poorer attachment was also more evident among primipara (30.0% compared to multipara (20.9% mothers. Parity was significantly associated with poor position (P = 0.028 and attachment (P = 0.002. Poor attachment was related to cracked nipples and mastitis. Preterm and low birth weight were significantly associated with poor attachment and poor effective suckling. Poor suckling was more (42.8% in the early neonatal period than late neonatal period (32.9%. Conclusions and Recommendations: Young (<20 years and primipara mothers were more in need of support and guidance for appropriate breastfeeding techniques. It is recommended that each mother should be observed for mother′s and infant′s positioning and attachment at the onset of breastfeeding and if needed subsequent counseling should be given on correct positioning and attachment.

    Full Text Available Four levels of stevia supplementation in the diet of suckling pigs with combination of two feeding methods in weaned pigs were studied. Twenty litters with nine piglets each were allocated to four groups and fed four dietary stevia supplementations (0, 0.2, 0.4 and 0.6% from 7 days old to 21 days, weanling age. Two male weanlings of average weight of each litter were selected and alloted to one of two feeding methods, one male was fed basal diet 1 continuously while the other was fed by alternating basal diet 2 and basal diet 1 for 35 days of experiment, according to the split plot in randomized complete block design.The results showed that piglets fed with 0.2 and 0.4% stevia in suckling diets had double daily feed intake compared to those fed 0% stevia in the diet (12.36 vs 5.93 g/d, but this difference was not statistically significant (P>0.05. The daily feed intake and average daily gain decreased when suckling pigs were fed with 0.6% stevia in the diet. Continuous or alternating feeding had no effect (P>0.05 on feed intake and growth performance of weaned pigs (aged 21-56 days fed with various levels of stevia supplementation in the diets. However, daily feed intake of weaned pigs fed with 0.4% stevia (748 g/d was significantly (P<0.01 higher than that of pigs fed with 0, 0.2 and 0.6% stevia in the diets (617, 649 and 589 g/d, respectively. Average daily gain followed the same pattern (507 vs 419, 455 and 401 g/d, respectively, P<0.01. Moreover, although feed cost per gain of piglets fed with 0.2 and 0.4% stevia in the diets were higher, the income was higher than those fed with 0% stevia in the diet.

    The modifying effect of the one compound on carcinogenicity of the other in the combined application is attributed usually to some changes in the carcinogen metabolism, i.e. its activation or inactivation. In this paper, when used separately, diethylnitrosamine (DENA) induced 4-6 times more neoplastic lesions in the liver of suckling mice than ortho-aminoazotoluene (OAT) did. However, after combined treatment with both carcinogens the total number of hepatic lesions was significantly lower than that in mice treated with DENA only. Similar effect was observed when OAT was administered 3 days before or 3 days after DENA injection. The observed protective effect is not mediated at metabolic level, because OAT has no effect on metabolism of DENA in mouse liver. Our findings can be unequivocally explained by the competition of the carcinogens for target protein molecules, presumably transcription factors, participating in hepatocyte differentiation, which differently interact with and are diversely impaired by different compounds.

    The effects of breed and slaughter weight on chemical composition, fatty acid groups, texture, and sensory characteristics of meat of 141 suckling male kids from 5 Spanish breeds were studied. There was a decrease in texture and lightness and hue angle with the increase of the slaughter weight. Fatty acid composition was correlated with the intramuscular fat content. All the breeds except MO had values of n-6/n-3 ratio below 4, which is the healthy limit recommended, and a low atherogenic index as well as a low intramuscular fat content. A multivariate analysis discriminated light kid, which had the most tender and juicy meat, from heavy kid which had more intense kid and milk odours. Blanca Andaluza and Pirenaica had most tender and juicy meat. The effect of slaughter weight on meat traits should be considered separately for each breed to find the most appropriate meat according to consumers preferences. PMID:22546814

    Full Text Available Numerous studies have evidenced significant differences in the carcass and meat quality of grass-fed and concentrate-fed lambs. The main differences regard carcass fatness (Murphy et al., 1994, subcutaneous fat colour (Prache and Theriez, 1999, meat colour (Priolo et al., 2002a and fatty acid composition (Enser et al., 1998. The use of grazing in lamb feeding favours the presence of substances in the meat which are beneficial to human health. Different methods, based on the spectrophotometric properties of fat have been proposed to verify the origin of the product (Priolo et al., 2002b. The objective of the present study is to verify if and to what extent the carcass quality of suckling lambs is affected by ewe feeding systems.

    With the aim of evaluating the effect of restricted suckling on the onset of follicular dynamics and body condition, multiparous Bos indicus cows were distributed in two groups. One group (RS=36) was subjected to a scheme of restricted suckling starting at 21 days postpartum. Calves were allowed to suckle once per day for a period of two h whilst the control group (C=18) remained with their dams at all times. At calving, body condition score, back fat thickness and body weight had similar values (p>0.05) for both groups. By day 85 postpartum both groups had recorded losses in body weight. The cows in the continuous group formed a greater (p0.05). The number of cows that exhibited estrus after 45 days, was greater (p0.05). A regime of restricted suckling favors the earlier growth of follicles and the prompt restoration of ovarian activity. PMID:26936657

    Previously published reports have indicated that postpartum anovulatory intervals can be markedly reduced and rebreeding performance enhanced in Bos taurus cows by eliminating nighttime suckling. We sought to confirm this hypothesis by examining the effects of day, nighttime, and ad libitum suckling on suckling behavior of calves, duration of the postpartum anovulatory interval, and pregnancy rates in 45 fall-calving Brahman x Hereford (F1) cows. Beginning on d 9 to 12 postpartum, calves were removed from lactating cows from 0700 to 1900 (Night-Suckled, n = 15) or from 1900 to 0700 (Day-Suckled, n = 15), or remained with their dams continuously (Ad Libitum-Suckled, n = 15). Cows in each group were maintained with fertile Angus bulls from d 10 postpartum until the first normal luteal phase or 100 d postpartum, whichever occurred first. Cows were observed for estrous behavior twice daily, and jugular blood samples were collected twice weekly for the determination of serum progesterone concentration. Mean number of suckling episodes per 24 h was greater (P or = 1 ng/mL (32+/-2.5, 32+/-4.5, and 31+/-1.7 d, respectively), first normal luteal phase (38+/-3.1, 38+/-3.8, and 37+/-2.5 d, respectively), and first estrus (43+/-3.5, 40+/-3.9, and 36+/-1.1 d, respectively) did not differ (P > .05) among the three groups. Similarly, cumulative pregnancy rates within 100 d after calving did not differ (P > .05). These results in Bos indicus x Bos taurus (F1) cattle do not support the previous conclusions in Bos taurus that eliminating nighttime suckling reduces the postpartum anovulatory interval.

  2. Effect of added Punica granatum peel fruits and Nigella sativa seeds on immunology and performance of suckling buffalo calves

    International Nuclear Information System (INIS)

    The use of feed additives is considered as a good source to improve the immunity status of newborn calves instead of chemical products because the residuals of chemical products may have side effects on human health on the long-run. Punica granatum fruits peel (Pg-p) has been shown to possess a significant antioxidant activity also valued for their therapeutic properties and used to remove intestinal tapeworm. On the other hand, seeds of Nigella sativa (NS) are rich in fatty acids (Linoleic and Linolenic acid), essential fatty acids and non-starch polysaccharide. Recently, clinical and animal studies have shown that extract of the NS seeds have many therapeutic effects such as immunomodilative, antibacterial, hypotensive, hepatoprotective, and antidiabetic effects. Thirty-six suckling buffalo claves (18 males and 18 females) were used in this study with average live body weight 38.44 ± 0.62 kg. The calves were divided into 3 groups, each group allotted to receive one of 3 tested starters throughout 105 d. The starter was offered without additive in the control group (G1), while it was mixed with 2% Pg-p in group (G2) and with 2% Pg-p plus 3% NS in group (G3). Weekly faecal swabs were collected from the experimental animals for bacteriological examination. Immunoglobulins (Ig) and blood metabolites were determined in blood serum. Three sets of digestion trials were carried out using 3 male calves of each group that fed the same tested rations. Milk consumption was not significantly different among groups while, starter and clover hay intake was significantly (P < 0.05) higher in G3 than those in groups G1 and G2. The total weight gain achieved by group G3 was greater than that of G1 and G2 groups by 25.60% and 7.80%, respectively. Blood TP was significantly (P < 0.05) higher in G3 than that in G1. An albumin value was relatively higher in G1 compared with the treated G2 and G3. Meanwhile, blood urea nitrogen was significantly greater in G2 in comparison with G1 and

Seis terneros Holstein, de 2 semanas de edad, murieron después de presentar anorexia y apatía. Otros animales del mismo establecimiento habían muerto de la misma forma seis meses antes. A la necropsia el abomaso estaba muy distendido con contenido fluido y oscuro, la mucosa estaba edematosa y presentaba gran cantidad de úlceras milimétricas y habían depósitos de fibrina en la serosa. En el ciego de un animal se observaron extensas areas de infarto. En frotis de la mucosa abomasal se observaron bacilos cortos Gram positivos, no esporulados, aislándose de ella un cultivo rico de C. perfringens tipo D. Es probable que la baja inmunidad de los terneros debido a falta de calostro y estrés alimenticio, haya sido el predisponente para la infección por C. perfringens tipo DAn outbreak of ulcerative abomasitis in suckling calves associated with Clostridium perfrigens type D infection is described. Six twoweek old Holstein calves died after showing loss of appetite and lethargy. Other animals had died in similar circumstances during the previous six months. At necropsy, the abomasum was severely distended with dark fluid and the mucosa was oedematous and covered with many millimetric ulcers, while the serous surface of this organ was covered with fibrin. Several irregular black areas of infarcts were observed in the cecum of one animal. Histologically, the abomasal mucosa showed ulcers and haemorrhage, while the submucosa showed severe oedema and infiltration of neutrophils, lymphocytes and plasma cells. Short, thick, nonsporulated Gram positive rods were observed on smears of abomasal mucosa. C. perfringens type D was isolated from the abomasal mucosa. Low immunity and stress could have contributed to the pathogenesis of the lesions described

    Suckling mice express colipase before the expression of pancreatic triglyceride lipase. Yet, efficient fat digestion in newborns requires colipase, suggesting that colipase may act as a cofactor for another lipase such as pancreatic lipase-related protein 2 (PLRP2). We determined whether PLRP2 or another lipase depends on colipase for maximal activity in newborn mice by analyzing extracts from the pancreas of 4-d-old colipase-deficient and PLRP2-deficient mice. Pancreatic extracts from colipa...

    We investigated differences between effects of natural- and bucket-suckling methods on basal serum oxytocin (OT) and cortisol concentrations, and the effect of OT concentration on affiliative and investigative behavior of calves to a novel object. Ten Japanese Black calves, balanced with birth order, were allocated evenly to natural-suckling (NS) and bucket suckling (BS) groups. Blood samples were collected at the ages of 1 and 2 months (1 week after weaning) calves, and serum OT and cortisol concentrations were measured using enzyme-linked immunosorbent assay and enzymeimmunoassay tests, respectively. Each calf at the age of 2 months (2 weeks after weaning) was released into an open-field with a calf decoy, and its investigative and affiliative behaviors were recorded for 20 minutes. In 1-month-old calves, the basal serum OT concentration (25.5±4.9 [mean±standard deviation, pg/mL]) of NS was significantly higher than that of BS (16.9±6.7) (p<0.05), whereas the basal cortisol concentration (5.8±2.5 [mean±standard deviation, ng/mL]) of NS was significantly lower than that in BS (10.0±2.8) (p<0.05). Additionally, a negative correlation was noted between serum OT and cortisol concentrations in 1-month-old calves (p = 0.06). Further, the higher serum OT concentration the calves had at 1 month old, the more investigative the calves were at 2 months old but not affiliative in the open-field with a calf decoy. Thus, we concluded that the natural suckling method from a dam elevates the basal serum OT concentration in calves, and high serum OT concentrations induce investigative behavior and attenuate cortisol concentrations.

    Full Text Available The objective of this study was to determine the effect of feeding a maternal diet supplemented with docosahexaenoic acid (DHA during the suckling period on the development of the immune system and oral tolerance (OT in offspring. Dams were randomized to consume one of two nutritionally adequate diets throughout the suckling period: control (N = 12, 0% DHA or DHA (N = 8, 0.9% DHA diet. At 11 days, pups from each dam were randomly assigned to a mucosal OT challenge: the placebo or the ovalbumin (OVA treatment. At three weeks, plasma immunoglobulins and splenocyte cytokine production ex vivo were measured. OVA-tolerized pups had a lower Th2 (IL-13 response to OVA despite the presence of more activated T cells and memory cells (CD27+, all p < 0.05. Feeding a high DHA diet improved the ability of splenocytes to respond to mitogens toward a skewed Th1 response and led to a higher IL-10 and a lower TGF-β production after stimulation with OVA (all p < 0.05. Untolerized DHA-fed pups had lower plasma concentrations of OVA-specific immunoglobulin E (p for interaction < 0.05. Overall, feeding a high DHA maternal diet improves the tolerance response in untolerized suckled pups in a direction that is thought to be beneficial for the establishment of OT.

    The effects of a diet with goat milk "GM" or milk replacer "MR" on the meat quality and fat composition of suckling Murciano-Granadina kids were studied. MR consisted of powdered skimmed milk, coconut oil and fat, and cereal products and by-products. Raw meat quality (moisture, protein, lipids, ash, collagen, cholesterol, haem pigments, CIELab colour, pH and water retention capacity), fatty acid "FA" composition and eating quality of cooked meat (odour, flavour and texture) were determined. Diet had only a slight effect on raw meat quality but had a pronounced effect on fatty acid composition and eating quality of cooked meat. MR diet increased the water/protein proportion in the muscle. The saturated/unsaturated FA ratio in GM and MR fat was 0.94 and 2.27, respectively. The major FA in GM and MR fat were C16:0 and C18:1, respectively. Short-chain C4-C12 hardly accumulated in the adipose tissue of suckling kid, increasing the relative percentages of C14-C20. This effect was more pronounced in MR fat, due to the fact that MR contained more short-chain fatty acids than GM. MR diet gave cooked meat a more intense characteristic goat meat odour and flavour, more tenderness and more juiciness than the natural suckling diet. This fact could be related to differences in meat and fat composition. PMID:22061547

    Meat colour was evaluated in 141 male suckling kids from five Spanish breeds: Blanca Andaluza (BA), Blanca Celtibérica (BC), Moncaína (MO), Negra Serrana-Castiza (NE) and Pirenaica (PI). Kids were slaughtered at 7.5 and 11.5 kg. pH and colour were measured in the longissimus thoracis et lumborum muscle. pH values did not differ significantly among breeds. Lightness tended to decrease and redness to increase as weight increased. BC and NE at light weight and BC and BA at heavy weight were characterized by greater lightness, chroma and hue. At both weights MO and PI were darker and showed lower values for chroma and hue. BA at light weight and NE at heavy weight were characterized by values that were between those of the former groups for all variables. Discriminant analysis based on colour and pH correctly classified 48.9% of the kids into their breed and slaughter weight. PMID:21041040

    Sexually stimulating behaviors that are not linked to reproduction are rare among non-human (especially non-primate) mammals. Such behaviors may have a function in the hierarchy of social species. In solitary species, such behaviors are more enigmatic, and possibly indicative of something abnormal. Here, we report on a case of two male brown bears, raised in captivity since being orphaned as cubs, which engaged in recurrent fellatio multiple times per day until at least 10 years old. The roles of provider and receiver in the act remained unchanged, and the behavior itself became highly ritualized. The provider always initiated the contact involving vigorous penile sucking that appeared to result in ejaculation. We suggest that the behavior began as a result of early deprivation of maternal suckling, and persisted through life, possibly because it remained satisfying for both individuals. This constitutes the first descriptive report of fellatio in bears, and suggests that some bears may suffer lifelong behavioral consequences from being orphaned at an early age. PMID:24899532

    Effects of suckling length (45, 75 and 120 days) and birth type (single and twin) on lamb growth, slaughtering and carcass quality characteristics were investigated using 40 Kivircik lambs. SC-45 and SC-75 lambs were weaned at 45 and 75 days of age, respectively, whilst SC-120 lambs remained with their mothers until the end of the experimental period. Lambs from all studied groups were slaughtered at 120 days of age. Weaning treatment caused a decrease in average daily gain in SC-45 and SC-75 lambs, and therefore, final weight was higher in SC-120 lambs than lambs from weaned groups. SC-120 lambs had higher empty body weight, cold carcass weight, dressing percentage, carcass measurements, carcass fatness (proportions of the kidney knob and channel fat, subcutaneous and intramuscular fat in pelvic limb) and non-carcass fatness (omental and mesenteric fat proportion) than weaned lambs. As a conclusion, the potential losses in meat production due to weaning should be considered before deciding the weaning of lambs at early ages. PMID:26676241

  14. Some effects of partial suckling on milk yield, reproduction and calf growth in crossbred dairy cattle in north east coastal Tanzania

    International Nuclear Information System (INIS)

    Two experiments are described where a progeny of Bos taurus x Bos indicus crossbred cows were reared by partial suckling or bucket rearing (Experiment I), and partially suckled calves were weaned at 12 or 24 weeks of age (Experiment II). The results of Experiment I suggest that calf rearing method had no significant effect in the yield of milk extracted from the cows by hand milking although there were effects on the shape of the lactation curve. Cows showed similar patterns of live weight and body condition losses and gains and there were no significant effects on the length of the post partum interval. Suckled calves were lighter at weaning (P <0.01) but there were no differences in live weight between treatments at 52 weeks of age. The main advantage of partial suckling was that the calves took advantage of residual milk which was estimated as 28-29% of the total yield. The results from Experiment II suggest that there were no advantages in terms of milk yield or calf growth by extending the suckling period to 24 weeks. The post partum intervals observed in Experiment II were substantially longer than those in Experiment I, possibly because of greater live weight/body condition losses experienced by cows in the second experiment.

  15. Transfer of 109Cd in the mother's body to the suckling infant mice through the milk and its distribution in their whole bodies

    International Nuclear Information System (INIS)

    To point out the transfer of injected 109Cd in mothers, body to suckled infant mice through the milk and its distribution in their whole bodies, the following experiments were performed. Pregnant mice received 8μ Ci of 109Cd by intravenous injection 7 days before parturition. After the delivery, the suckled infant mice were killed and fixed by momentary freezing in the refrigerated room of -15 deg C every day from 1 to 5 days and 10 days after the births. 109Cd was found in the intestines of the suckled infant mice from 1 to 5 days after the births, but no trace of 109Cd was confirmed there 10 days after the births. Mother mice had been given the same dose of 109Cd shortly after the parturition, and gave suck to her infants. The suckled infants were killed and fixed 7 and 10 days after the births by the same method. All specimens were investigated by whole body autoradiography. 109Cd was observed in the gastrointestinal tract of the suckled infant mice 7 and 10 days after the births. No clear evidence was obtained in the experiments to support that 109Cd had been absorbed from the gastrointestinal tracts. However, final conclusion cannot be drawn from these small number of samples, and further work is needed. (Kobatake, H.)

    Full Text Available A 2-sample regime was used to measure whole milk progesterone concentration on the day of oestrus and insemination (Day 0 and 6 days later (Day 6 in a sample of 50 primiparous and 100 multiparous suckling beef cows. Exposure to teaser bulls and observation by cattlemen identified the occurrence of oestrus. Three sets of criteria used to define ovulatory oestrus were compared : a milk progesterone concentration less than 6 nmol / l on Day 0 ; b milk progesterone less than 6 nmol / l on Day 0 and rising to greater than 6 nmol / l on Day 6; c milk progesterone less than 6 nmol / l on Day 0 and rising to greater than 6 nmol / l on Day 6, or cow diagnosed pregnant to 1st insemination. Using only a single milk sample on Day 0 (criterion a would have resulted in the positive predictive value of heat detection being estimated at 98.7%. Using a paired measurement (criterion b resulted in a significantly lower estimate of 84.7%. The inclusion of cows that conceived despite not showing a marked rise in milk progesterone concentration (criterion c resulted in a more accurate estimate of 89.3%. Use of a 2-sample regime also allowed calculation of conception rates while eliminating the effect of heat detection errors. In the cows sampled, of those in ovulatory oestrus that were inseminated, 73.1% conceived to the 1st insemination. These results demonstrate that artificial insemination within a limited breeding season can be successful if nutrition is optimal and management is intensive. The use of a 2-sample milk progesterone test may be a valuable tool in investigating heat detection and conception problems in beef herds in which artificial insemination is used.

    Nutrition in early life is important in determining susceptibility to adult obesity, and arginine may promote growth acceleration in infants. We hypothesized that maternal arginine supplementation may promote growth in their pups and contribute to obesity and alteration of the metabolic system in later life. Dams and pups of Wistar rats were given a normal diet (15% protein) as a control (CN) or a normal diet with 2% arginine (ARG). Altered profiles of free amino acids in breast milk were observed in that the concentrations of threonine and glycine were lower in the ARG dams compared with the CN dams. The offspring of the CN and ARG dams were further subdivided into normal-diet (CN-CN and ARG-CN) groups and a high fat-diet groups (CN-HF and ARG-HF). In response to the high fat-diet feeding, the visceral fat deposits were significantly increased in the ARG-HF group (although not compared with the CN-HF group); no difference was observed between the CN-CN and ARG-CN groups. The blood glucose and insulin levels after glucose loading were significantly higher in the ARG-HF group compared with the CN-HF group. The results suggest that the offspring of dams supplemented with arginine during lactation acquired increased susceptibility to a high-fat diet, resulting in visceral obesity and insulin resistance. The lower supply of threonine and glycine to pups may be one of the contributing causes to the programming of lifelong obesity risk in offspring. Our findings also indicated that maternal arginine supplementation during suckling causes obesity and insulin resistance in rats. PMID:27188903

    pDVWS501 was a genomic-length cDNA clone of dengue 2 virus, through which infectious virus (MON501) could be rescued. MON501 was neurovirulent in mice, whose E residues 62 and 203 were Lys and Asn, respectively. Two genomic-length cDNA clones (TB62 and TB203) were constructed by pointed mutation of pDVWS501 with OL-PCR, E62 of TB62 and E203 of TB203 were converted to Glu and Asp, respectively. RNA transcripts of pDVWS501, TB62 and TB203 were produced in vitro and electroporated into BHK-21 cells. The cultures were collected after 7 days and used as inoculum to infect C6/36 cells. The existence of rescued dengue viruses in the culture was proved by RT-PCR, and the typical cytopathic effect (CPE) of C6/36 caused by dengue virus emerged after 2-5 days' inoculation. Sequence analysis further confirmed the existence of recovered and recombinant DEN2 viruses, whose 5′ termini had an additional non-virus nucleotides "G", while the 3′ terminal sequences remained the same as natural. The neurovirulence of three viruses was evaluated in 1-day-old mice by the intracerebral route with 105-102 TCID50. Compared with MON501 group, the number of infected mice with the signs of encephalitis in HFT62 and HFT203 groups was less, and the surviving time was longer. The properties of these mutants demonstrated that E62 and E203 are determinants of suckling mice neurovirulence.

    Full Text Available Interest in the preservation of autochthonous breeds such as the Blanca Andaluza goat (meat breed, raised under grazing-based management, has recently increased among Spanish farmers. A study of the possibilities of transformation to organic production needs to analyze the quality of their products. The aim of this study was to evaluate the fatty acid (FA composition of muscle and adipose tissues of Blanca Andaluza goat kids under organic and conventional grazing–based management system. Twenty-four twin kids (12 males, 12 females were selected from each system. The FA profile was determined in the longissimus thoracis muscle, kidney and pelvic fat. The percentages of C17:0, C17:1, C20:1, C20:4 n-6, C22:2 and several n-3 FAs were higher in organic meat; C12:0, C18:1 trans-11, CLA and C20:5 n-3 were lower in organic meat. The fat depots from the conventional kids showed lower percentages of C12:0, C14:0, C15:0, C17:0, C17:1, C18:3 n-3 and atherogenicity index, and higher percentage of C18:0. In the pelvic fat, the conventional kids displayed lower percentages of C16:0, C18:2 n-6 cis, PUFA, n-3 and n-6 FAs, and greater percentages of C18:1 n-9 cis and MUFA. The conventional kids displayed a major n6:n3 ratio in the kidney fat. No gender differences were observed. Significant differences were found only in some FA percentages of muscle and adipose tissues of suckling kids raised in organic and conventional livestock production systems, and due to this reason conventional grazing–based management farms could easily be transformed into organic production.

    Full Text Available The objective was to assess the effects of a concentrate consisting of two types of corn: flint and dent, with three different grinding degrees (1, 3 and 5 mm, as a function of intake, performance and digestibility of three crossbred dairy suckling heifers. A randomized block design involving 54 crossbred heifers in a 2 × 3 factorial arrangement was used to assess intake and performance patterns. In order to assess digestibility, the experimental design was completely randomized, consisting of 24 crossbred heifers. Weighting and measurements of height at withers and thoracic perimeter were performed. There was no significant interaction between grinding degree and corn type for any of the studied variables. The daily intake of concentrate dry matter was higher for flint corn (243 g/day as compared with dent corn (160 g/day. The grinding degree caused difference in the dry matter, crude protein and ether extract intake, with higher intake when 3 and 5 mm sieves were used in the process. There was no difference regarding average daily gain and increased withers, croup and thoracic perimeter. Likewise, feed conversion did not differ. Regarding dry matter digestibility, there was an effect resulting from the hardness of corn (78.9% for dent, and 84.3% and for flint corn. As for the grinding degree, the highest value of dry matter digestibility was found when using 5 mm sieves (84.2%, whereas the percentage values found for 1 mm and 3 mm mesh sieves were 79.1% and 78.1%, respectively. It is recommended that heifer calves in the early stage of growth be fed flint corn ground through 3 or 5 mm mesh sieves.

  1. Reproductive performance of dairy cows suckled or milked three or six times daily

    International Nuclear Information System (INIS)

    During 6 weeks after calving 29 dairy cows were kept in three treatment groups: M3 - milked three times daily, M6 - milked six times daily, and S - milked three times and suckled three times daily. During weeks 7-18 all the cows were milked three times daily. Throughout the experiment a diet of 65% concentrate was fed ad-libitum. Visual observations of sexual behaviour were carried out four times daily. Cows were inseminated commencing 59 days post-partum. Blood was collected three times per week for progesterone, glucose and FFA determinations analysis. Milk production during the first 6 weeks was 35.3, 42.6 and 50.0 kg/day (P<0.01) and during the whole 18 weeks 36.7, 42.5 and 41.7 kg/day (P<0.05) for cows of the M3, M6 and S groups respectively. Dry matter intake during the first six weeks was 16.8, 19.4 and 16.2 kg/day (P<0.05), and body weight loss during this period was 23.3, 31.4 and 59.1 kg (P<0.05) for cows of the M3, M6 and S groups respectively. In groups M3, M6 and S the first ovulation occurred on average 26, 37 and 48 days post-partum (P<0.01), conception rate was 27, 18 and 45% (P<0.01) and pregnancy rate at 150 days post-partum was 80, 33 and 80% (P<0.05) respectively.

    Full Text Available The effect of goat production systems was evaluated on the concentration of conjugated linoleic acid (CLA in meat obtained from suckling kids. Twenty male Ionica suckling kids fed only on maternal milk were subdivided into two groups of 10 subjects each according to their dams’ feeding treatment: kids in Group I were raised under dams reared by an intensive production system, while those of Group E were raised under dams grazing on pasture. Kids were slaughtered when 45 days old. The goat production system had no effect on kids’ growth rates, slaughtering yield and on the percentages of lean, fat and bone of the lumbar region and pelvic limb cuts. The pH value of the Longissimus lumborum (Ll muscle 45 min after slaughter was higher in Group I (6.73 vs 6.54; P<0.05. Meat colour of Group E kids was lighter (50.63 vs 48.86 and showed greater (P<0.05 yellowness (13.42 vs 11.93 and Chroma values (14.92 vs 13.45. Cooking loss was higher in Group E (31.51 vs 26.98%; P<0.05, but meat tenderness of the Ll muscle was better (peak force of 2.86 vs 3.58 kg/cm2; P<0.05. Meat chemical composition did not differ between the two groups for either raw or cooked samples. On the whole, suckling kids raised under grazing goats showed a higher total CLA concentration in both raw (2.57 vs 2.25% on total fatty acids and cooked meat (1.85 vs 1.44%, although the differences were not significant.

    We examined the potential of overt carnitine palmitoyltransferase (CPT I) to control the hepatic catabolism of palmitoyl-CoA in suckling and adult rats, using a conceptually simplified model of fatty acid oxidation and ketogenesis. By applying top-down control analysis, we quantified the control exerted by CPT I over total carbon flux from palmitoyl-CoA to ketone bodies and carbon dioxide. Our results show that in both suckling and adult rat, CPT I exerts very significant control over the pathways under investigation. However, under the sets of conditions we studied, less control is exerted by CPT I over total carbon flux in mitochondria isolated from suckling rats than in those isolated from adult rats. Furthermore the flux control coefficient of CPT I changes with malonyl-CoA concentration and ATP turnover rate. PMID:8912677

    aglutination test. The most commonly diagnosed etiological agent in suckling pigs with diarrhea was E. coli (34% alone and 24% associated, followed by Salmonella sp, Rotavirus and Campylobacter sp. IHC identified antigen with the isolation of E. coli, in ten pigs, in one with Salmonella sp and in five without ethiological diagnosis. The most frequent fimbrial antigen found was F41 in eight pigs aged 1 to 35 days, followed by the association F4-F41 in five animals with ages ranging between 15 to 28 days and finally, F4 in three pigs between 8 and 35 days. The results confirm the importance of fimbrial antigens as adhesion factor on enteropathogenic E. coli in the small intestine of suckling pigs, since the effectiveness of inmunohistochemistry for identity the fimbrial antigen in paraffin embedded intestines

    Full Text Available Abstract In the study, a method called "hardening in liquid phase" for preparing chitosan granules with glutaraldehyde as crosslinker and Tween 80 as surfactant and paraffin liquid as dispersant was established. The chitosan granules were light yellow and insoluble in water or oil, but they swelled in acid solution and narrowed in neutral or alkaline solution. Furthermore, some of characteristics of the chitosan granules were revealed. (a Stability: Their shapes were stable at pH 7.0 and pH 8.0 and -30°C~120°C. The shelf life is at least one year in vitro at room temperature. (b Safety: Some experiments of their lethal effect to suckling mice and pathogenicity to mature mice proved the chitosan granules were harmless. (c Antiviral activity: Some suckling mice injected with chitosan granules were still alive or delayed death compared with control group when they challenged with foot-and-mouth disease virus (FMDV. Such anti-FMDV capacity could maintain 1 week and was the strongest on the third day.

    Full Text Available The research was carried out on 6 “Italian Heavy Draught Horse” orphan foals ar- tificially suckled by an automatic milk feeder. The purpose of the research was to show that artificial weaning does not have a negative effect on a foal’s growth and welfare. The foals were reared in an indoor box, weighed every 3 weeks from day 4 after birth and observed for 24 consecutive hours at the age of 4, 10, 47, 114, 142 and 176 days, to compile an ethogram which includes biorhythms, and social, alimentary and eliminative behavioural patterns. During the study, “daily weight gains” were greater than 1610 g/d; but between 26 and 46 days and after weaning, values were lower than 1230 g/d, and between 172 and 193 days, prior to slaughtering, they were of 1090 g/d. Age had a significant (P<0.001 on almost all the ethological parameters considered, above all for the time spent lying down above all for the time spent lying down and the licking structures (P<0.01, and for the drinking bouts (P<0.05. The period of adaptation to artificial feeding certainly lasted at least two weeks. These results suggest that the technique of artificial suckling can be applied to horses without negative effects on growth and welfare, any subjects showed abnormal behaviour.

  12. Feeding Value of Corn Gluten Meal as a Source of Protein in Creep Feeding Diets of Suckling Lambs

    International Nuclear Information System (INIS)

    Forty-two newly born lambs were randomly divided into three similar groups, their weights were recorded at birth then each two weeks. Lambs in the groups were left to suckle their mothers, in addition to one of the experimental diets (as creep feeding), which found in Table (1). First group (Gl) fed diet contains 13% soybean meal (SBM) and served as a control diet, second group (G2) fed diet contains 6.5% SBM and 6.5% corn gluten meal (CGM), and third group (G3) fed diet contains 13% CGM. The concentrate feed mixture was offered daily started at 7th days of age until weaning. Blood samples were taken at 7, 40 and 80 days of age. The results showed that averages daily body weight gain and weaning weight of lambs were higher significantly with G2 than G3 then Gl. In addition, male lambs had higher weaning weight and average daily weight gain than female lambs in the three groups. The highest means of serum total proteins, albumin and globulin recorded with G2 followed by G3 then Gl o Means of serum glucose significantly decrease with age. Blood serum aspartate amino -transferase (AST) and alanine amino - transferase (ALT) creatinine concentration and T3 level were not affected by treatments. Serum triglyceride and serum cholesterol levels were higher recorded for Gl and G2 than G3. It is concluded that adding corn gluten meal to creep feeding diets improves growth of suckling lambs without any side effects on physiological body function of lambs

    (/sup 14/C)polychlorinated biphenyls (PCBs (KC-600)) were administered orally to female rats at the dose of 10 mg/kg in olive oil once a week for five weeks. Four weeks after the last administration of (/sup 14/C)PCBs, they were mated with untreated males. The distribution of total /sup 14/C was examined in maternal and offspring tissues. The average amount of PCB accumulated in dams was 44.2% of the dose two weeks after the last administration. The average amount transferred from dam to fetus was 0.003% accumulated in the dam. In the fetus, the highest concentration was found in the fetal placenta followed by the liver, heart, skin, muscle, blood, lung, and brain. The PCBs level in fetal blood was the same as in maternal blood. The average concentration of PCBs in milk was 1.84 ppm. The amount transferred to sucklings increased gradually to about 5% of the maternal PCBs. In suckling rats, PCBs were distributed at the highest concentration in adipose tissues and at intermediate concentrations in the skin, adrenal gland, and liver. The liver to body weight ratio of offspring was significantly increased on the 11th and 25th days after birth. The nursing rats had lower PCBs concentrations compared with the pregnant and virgin rats. The organ concentrations of PCBs in dam and offspring were about ten times as high as those found after treatment with Kanechlor-400. These results may suggest that PCBs with higher chlorine content remained in tissues for a longer period of time.

    The cyanobacterial neurotoxin β-N-methylamino-L-alanine (BMAA) has been implicated in the etiology of neurodegenerative disease and proposed to be biomagnified in terrestrial and aquatic food chains. We have previously shown that the neonatal period in rats, which in humans corresponds to the last trimester of pregnancy and the first few years of age, is a particularly sensitive period for exposure to BMAA. The present study aimed to examine the secretion of (14)C-labeled L- and D-BMAA into milk in lactating mice and the subsequent transfer of BMAA into the developing brain. The results suggest that secretion into milk is an important elimination pathway of BMAA in lactating mothers and an efficient exposure route predominantly for L-BMAA but also for D-BMAA in suckling mice. Following secretion of [(14)C]L-BMAA into milk, the levels of [(14)C]L-BMAA in the brains of the suckling neonatal mice significantly exceeded the levels in the maternal brains. In vitro studies using the mouse mammary epithelial HC11 cell line confirmed a more efficient influx and efflux of L-BMAA than of D-BMAA in cells, suggesting enantiomer-selective transport. Competition experiments with other amino acids and a low sodium dependency of the influx suggests that the amino acid transporters LAT1 and LAT2 are involved in the transport of L-BMAA into milk. Given the persistent neurodevelopmental toxicity following injection of L-BMAA to neonatal rodent pups, the current results highlight the need to determine whether BMAA is enriched mother's and cow's milk.

    The neonatal period is often polarised to T helper (Th2) response at the time of birth, predisposing offspring to allergic disorders. Passive immunity through the mother's milk is critical for immune system development of newborns. Probiotics have been proposed to harmonise Th1/Th2 imbalance in allergic conditions in adults. In the present study, the anti-allergic effects of feeding probiotic Lactobacillus rhamnosus-fermented milk (PFM) either to dams during the suckling period or to their offspring after weaning individually or else in successive periods against ovalbumin (OVA)-induced allergy in newborns was analysed. After allergen sensitisation, physical symptoms of allergy, gut immune response, humoral immune response and cell-mediated response through interleukins were detected. Consumption of PFM by mothers and offspring showed a reduction (P<0·01) in physical allergic symptoms in newborns with an increase (P<0·01) in the numbers of goblet and IgA+ cells in the small intestine. Similarly, considerable (P<0·001) decreases in OVA-specific antibodies (IgE, IgG, IgG1) and ratios of IgE/IgG2a and IgG1/IgG2a in the sera of newborn mice were recorded. A decrease in IL-4 and an increase in interferon-γ levels further confirmed the shift from Th2 to Th1 pathway in PFM-fed mice. It is logical to conclude that the timing of PFM intervention in alleviating allergic symptoms is critical, which was found to be most effective when mothers were fed during the suckling period.

    Porcine circovirus type 2 (PCV2) is the assumed causative agent of a number of different diseases summarized as porcine circovirus diseases (PCVD). The virus is shed via different se- and excretions of PCV2 infected pigs. Transmission of the virus occurs horizontally and vertically either by oronasal or diaplacental infection. Recent research emphasizes the importance of diaplacental PCV2 infection or the infection in early stages of the piglet's life attributable to excretion of PCV2 by the dams within the suckling period. To estimate the prevalence of intrauterine PCV2 infections under field conditions in Bavaria the PCV2 status of farrowing sows (n=198) and corresponding pre-suckling piglets (n=590) of 20 piglet producing farms was examined. PCV2 viral load and anti-PCV2 antibodies in the serum of the sows and piglets were examined at time of farrowing or before colostrum intake, respectively. PCV2 excretion of the sows via saliva, feces and urine was examined additionally. PCV2 specific antibodies in the serum of the sows were detectable on 11 farms with a mean in herd seroprevalence of 35.5% in these farms. Only 0.65% of all samples collected from 198 sows were positive for PCV2 DNA (serum: 1%; feces: 0.5%; saliva: 0.5%; urine: 0.6%). PCV2 DNA was detectable in sample material from seronegative sows as well as from seropositive sows. In none of the pre-suckling serum samples of the piglets IgG antibodies against PCV2 or PCV2 DNA were present. No correlation between the antibody- and viremia status of the sows and the PCV2 excretion was detectable. In contrast to reports about a high prevalence of viremic pre-suckling piglets in the suckling period in North America, the results of the present study reveal that diaplacental infection with PCV2 is comparatively rare in Southern Germany and infection of piglets within the suckling period seems to be more likely.

    Lattice animals provide a discretized model for the theta transition displayed by branched polymers in solvent. Exact graph enumeration studies have given some indications that the phase diagram of such lattice animals may contain two collapsed phases as well as an extended phase. This has not been confirmed by studies using other means. We use the exact correspondence between the q --> 1 limit of an extended Potts model and lattice animals to investigate the phase diagram of lattice animals ...

  11. [Transgenic animals and animal welfare

    1998-01-01

    Under the pressure of a public vote in Switzerland (7 June 1998) on an initiative to ban the production, use and patenting of transgenic animals, their value for biomedical research and development is intensely debated. In addition, the Swiss legislation has adopted (1992) a constitutional obligation to "take into account the dignity of creatures". The term "dignity of creatures", however, can be interpreted in anthropocentric or biocentric ways. The government has now formulated the legal implications of this term for transgenic animals and plants in various laws including the animal and environmental protection laws. This paper gives arguments for a fair evaluation of trangenic animals from an animal welfare point of view where not only the costs of animal suffering must be considered but also the probability of potential benefit for man. A self-confident research community should allow such an evaluation procedure even in view of an outcome which could ban many uses of transgenic animals PMID:11208266

    Pavlov and Thorndike pioneered the experimental study of animal learning and provided psychologists with powerful tools to unveil its underlying mechanisms. Today's research developments and theoretical analyses owe much to the pioneering work of these early investigators. Nevertheless, in the evolution of our knowledge about animal learning, some initial conceptions have been challenged and revised. We first review the original experimental procedures and findings of Pavlov and Thorndike. Next, we discuss critical research and consequent controversies which have greatly shaped animal learning theory. For example, although contiguity seemed to be the only condition that is necessary for learning, we now know that it is not sufficient; the conditioned stimulus (CS) also has to provide information about the occurrence of the unconditioned stimulus (US). Also, animals appear to learn different things about the same stimuli when circumstances vary. For instance, when faced with situations in which the meaning of a CS changes, as in the case of acquisition and later extinction, animals seem to preserve the original knowledge (CS-US) in addition to learning about the new conditions (CS-noUS). Finally, we discuss how parallels among Pavlovian conditioning, operant conditioning, and human causal judgment suggest that causal knowledge may lie at the root of both human and animal learning. All of these empirical findings and theoretical developments prove that animal learning is more complex and intricate than was once imagined. Copyright © 2009 John Wiley & Sons, Ltd.

  18. Effect of undernutrition and hormone treatments on the absorption of proteins in suckling rat intestine

    International Nuclear Information System (INIS)

    The absorption of 125I-labeled BSA and gamma-globulin was significantly (P less than 0.01) elevated in UN pups compared to the controls. Administration of pharmacological doses of cortisone, thyroxine, and insulin markedly (P less than 0.001) reduced the absorption of BSA and gamma-globulin in UN pups. There was no significant difference in the binding of 125I-labeled BSA and gamma-globulin to microvillus membrane in the control and experimental animals. However, the degradation of labeled BSA and gamma-globulin by luminal content was considerably higher (55-70%) in controls compared to UN pups. This suggested that observed increase in the absorption of proteins in nutritionally deprived pups was unrelated to their binding to the microvillus surface but presumably it is a consequence of reduced luminal degradation together with delayed maturational development as suggested by the pattern of brush border enzymes in the UN intestinal tissue

    Many of us think that all wild animals are dangerous. In fact, very few of them will eat a man if he leaves them alone. If you meet a tiger, I'm sure you will run away, but even a tiger doesn't like meeting a man if it isn't hungry. Tigers only kill and eat man when they are too old to catch their food, such as sheep and other small animals. Some animals get frightened when they only smell a man. Some of themst and and look at a man for a short time before they run away.

    Sixteen purebred Iberian (IB) sows were used in two consecutive trials to determine the efficiency of conversion of sow's milk into piglet body weight (BW) gain and the relationship between milk protein and body protein retention and between milk energy yield and body energy retention in the nursing IB piglet. In each trial, four sows were selected in order to evaluate their milk production, litter growth and nutrient balance measurements, together with four additional sows for milk sampling. Litter size was equalized to six piglets. Daily milk yield (MY) was determined weekly by the weigh-suckle-weigh technique over a 34-day lactation period. Piglets were weighed individually at birth and then weekly from day 5 of lactation. Milk samples were collected on days 5, 12, 19, 26 and 34 post partum. The comparative slaughter procedure was used to determine piglet nutrient and energy retention. One piglet from each litter was slaughtered at birth and four on the morning of day 35. Total MY was on average 5.175 ± 0.157 kg/day. The average chemical composition (g/kg) of the milk was 179 ± 4 dry matter, 53.4 ± 1.0 CP, 58.5 ± 3.8 fat, 10.4 ± 0.3 ash and 56.9 ± 2.3 lactose. Milk gross energy (GE) was 4.626 ± 0.145 MJ/kg. Milk intake per piglet tended to increase in trial 2 (832 v. 893 g/day; P = 0.066). Piglet BW gain contained (g/kg) 172.1 ± 1.3 protein, 151.5 ± 3.5 fat, 41.4 ± 0.6 ash and 635 ± 3 water and 10.127 ± 0.126 MJ GE/kg. Throughout the 34-day nursing period, the piglets grew at an average rate of 168 ± 3 g/day. The ratio of daily piglet BW gain to daily MY was 0.195 ± 0.002 g/g and the gain per MJ milk GE intake was 41.9 ± 0.5 g/MJ. The overall efficiency of protein accretion (g CP gain/g CP milk intake) was low and declined in trial 2 (0.619 v. 0.571; P = 0.016). Nutrient and energy deposition between birth and weaning were 27.4 ± 0.5 g/day protein, 24.2 ± 0.8 g/day fat and 1615 ± 40 kJ/day energy. Piglet energy requirements for maintenance were

    Full Text Available This work aimed to study the probiotics association in 144 piglets from birth to 62 days old. In lactation, the design was completely randomized with two treatments, CTL, 1 mL of distilled water and ProbA, 5g in 15 ml of distilled water, both orally, and in the nursery in randomized block design, with 2x3 factorial arrangement of treatments, ProbA ProbB: 30g/ton of ProbB in the ration; CTL ProbB: 30g/ton of ProbB in the ration; ProbA ProbA, CTL CTL; ProbA CHA (challenged; CTL CHA. At 35 days of age the animal of the nursery were inoculated with Salmonella typhimurium orally. There was no effect of the parameters evaluated during the maternity. In nursery, the feed conversion was favorable to the ProbA. In the evaluation of fecal score, the challenged group had more diarrhea and increased elimination of S. typhimurium. Results showed the positive action of probiotics when applied at birth by the direct influence on the formation of the intestinal microbiota.

Totally 40 Aberdeen Angus cows were selected for observation. Calving all of cows was situated into March. The feeding ration for the animals was comprised by pasture during the grazing period and corn silage, hay and granulated distiller’s grains during the winter period. At average age 9 days before calving, and subsequently 10, 81, 151, 189 and 273 days after calving, blood was sampled and analysed for glucose and NEFA (non-esterified fatty acid concentrations on KONELAB T20xt automatic analyser (Thermo Fisher Scientific, Finland and currently available commercial kits (Biovendor-Laboratorni medicina, Czech Republic. A rapid increase (p < 0.05 of glucose concentration was detected in blood plasma of cows in period before calving to 81 days post partum. Average value of glucose concentration at 273 days postpartum was significant (p < 0.05 lower comparing to day 189. The highest concentrations of NEFA in blood plasma of cows were found at 10 day postpartum. After that, during the persisted higher temperature period the NEFA concentration decreased significantly (p < 0.01 till 189 days postpartum. At the end of monitored period concentration of NEFA in blood plasma significantly decreased (p < 0.05. Changes of hot and cold season during the grazing period probably according to forage quality and had significant effects on blood plasma NEFA and glucose concentrations.

    Isospora suis, a common intestinal parasite of piglets, causes neonatal porcine coccidiosis, which results in reduced and uneven weaning weights and economic losses in pig production. Nevertheless, there are no detailed studies available on the immune response to I. suis. The aim of this study was to carry out phenotypical characterization of lymphocytes during primary infections on day 3 after birth. Infected and noninfected piglets were investigated between days 7 and 16 after birth. Lymphocytes from the blood, spleen and mesenteric lymph nodes (flow cytometry) and of the jejunal mucosa (immunohistochemistry) were analysed. A decrease in T cells, especially with the phenotype of resting T-helper cells, T-cell receptor-gammadelta-T cells, and regulatory T cells in the blood, spleen and mesenteric lymph nodes was noticeable. An increase in cells with the phenotype of natural killer cells in the spleen of infected animals was found, and the subset of TcR-gammadelta-T cells was strongly increased in the gut mucosa. Our findings suggest an accelerated migration of those cells into the gut. This study provides a strong indication for the involvement of adaptive and innate immune response mechanisms in the primary immune response to I. suis, especially of TcR-gammadelta-T cells as a linkage between innate and adaptive immunity.

    Full Text Available The human anti-rabies pre-exposure treatment currently used in Brazil, employing a 1-ml dose of suckling mouse brain vaccine (SMBV administered on days 0, 2, 4 and 28, was compared to an alternative treatment with two 1 ml-doses on day 0, and one 1 ml-dose injected on days 7 and 21. The latter induced higher virus-neutralizing antibody (VNA titers on day 21. Both Brazilian rabies vaccines produced with PV or CVS rabies virus strains were tested. Two additional volunteer vaccinee groups, receiving the pre-exposure and the abbreviated post-exposure schedules recommended by the WHO using cell-culture vaccine (CCV produced with PM rabies virus strain, were included as reference. The VNA were measured against both PV and CVS strains on days 21, 42 and 180 by the cell-culture neutralization microtest. The PV-SMBV elicited higher seroconversion rates and VNA by day 21 than the CVS-SMBV. Both, however, failed to induce a long-term immunity, since VNA titers were <0.5 IU/ml on day 180, regardless of the schedule used. Cell-culture vaccine always elicited very high VNA on all days of collection. When serum samples from people receiving mouse brain tissue were titrated against the PV and CVS strains, the VNA obtained were similar, regardless of the vaccinal strain and the virus used in the neutralization test. These results contrast with those obtained with sera from people receiving PM-CCV, whose VNA were significantly higher when tested against the CVS strain.

    Molecular regulation of fatty acid desaturase (Fads) gene expression by dietary arachidonic acid (ARA) and docosahexaenoic acid (DHA) during early post-natal period, when the demand for long chain polyunsaturated fatty acids (LC-PUFA) is very high, has not been well defined. The objective of the current study was to determine regulation of liver Fads1, Fads2 and Fads3 classical (CS) and alternative transcripts (AT) expression by dietary ARA and DHA, within the physiological range present in human breast milk, in suckling piglets. Piglets were fed one of six milk replacer formula diets (formula-reared groups, FR) with varying ARA and DHA content from days 3-28 of age. The ARA/DHA levels of the six formula diets were as follows (% total fatty acid, FA/FA): (A1) 0.1/1.0; (A2) 0.53/1.0; (A3-D3) 0.69/1.0; (A4) 1.1/1.0; (D2) 0.67/0.62; and (D1) 0.66/0.33. The control maternal-reared (MR) group remained with the dam. Fads1 expression was not significantly different between FR and MR groups. Fads2 expression was down-regulated significantly in diets with 1:1 ratio of ARA:DHA, compared to MR. Fads2 AT1 expression was highly correlated to Fads2 expression. Fads3 AT7 was the only Fads3 transcript sensitive to dietary LC-PUFA intake and was up-regulated in the formula diets with lowest ARA and DHA contents compared to MR. Thus, the present study provides evidence that the proportion of dietary ARA:DHA is a significant determinant of Fads2 expression and LC-PUFA metabolism during the early postnatal period. Further, the data suggest that Fads3 AT7 may have functional significance when dietary supply of ARA and DHA are low during early development. PMID:24075244

  9. Impacts of birth weight on plasma, liver and skeletal muscle neutral amino acid profiles and intestinal amino acid transporters in suckling Huanjiang mini-piglets.

    Full Text Available Genetic selection strategies towards increased prolificacy have resulted in more and more increased littler size and incidences of impaired fetal development. Low birth weight (LBW piglets, with long-term alterations in structure, physiology and metabolism, have lower survival rates and poor growth performance. The aim of the study was to compare the plasma, liver and skeletal muscle contents of neutral amino acids (NAA and the intestinal expression of NAA transporters between LBW and high birth weight (HBW suckling Huanjiang mini-piglets. Forty piglets with either LBW or HBW (20 piglets per group were sampled on day 0, 7, 14 and 21 of age to give 5 observations per day per group. The contents of NAA in plasma, liver and skeletal muscle were measured, and jejunal expression of transporters for NAA, including Slc6a19 (B(0AT1 and Slc1a5 (ASCT2, were determined by real-time RT-PCR and Western Blot, respectively. Results showed that the suckling piglets with LBW had higher contents of Thr, Ser, Gly, Ala, Val, Met, Ile, Leu, Tyr, Phe and Pro in liver, and Gly in skeletal muscle, whereas lower contents of Met, Ser and Ala in plasma when compared with the HBW littermates. Consistent with the content differences in plasma NAA, the jejunal expression profiles of both Slc6a19 (B(0AT1 and Slc1a5 (ASCT2 in the LBW piglets were lower in compared with the HBW littermates during the early suckling period. These findings suggested that intestinal dysfunction in the LBW piglets may be one of the reasons in altered physiology and metabolism states of other organs, which result in lower survival and growth rate.

Três estratégias principais têm sido utilizadas para identificar esses genes - mapeamento de QTL, genes candidatos e sequenciamento de DNA e mRNA - e cada uma tem suas vantagens e limitações. O mapeamento de QTL permite determinar as regiões genômicas que contêm genes, mas o intervalo de confiança do QTL pode ser grande e conter muitos genes. A estratégia de genes candidatos é limitada por causa do conhecimento ainda restrito das funções de todos os genes. Os sequenciamentos de genomas e de sequências expressas podem auxiliar na identificação da posição de genes e de vias metabólicas associadas à característica de interesse. A integração dessas estratégias por meio do desenvolvimento de programas de bioinformática permitirá a identificação de novos genes de interesse zootécnico. Assim, os programas de melhoramento genético se beneficiarão pela inclusão da informação obtida diretamente do DNA na avaliação do mérito genético dos plantéis disponíveis.Animal biotechnology is providing new tools for animal breeding and genetics and thus contributing to advances in production efficiency and quality of animal products. However, the progress is slower than anticipated, mainly because of the difficulty involved in identifying genes that control phenotypic characteristics of importance to the animal industry. Three main strategies: QTL mapping, candidate genes and DNA and mRNA sequencing have been used to identify genes of economic interest to animal breeding and each has advantages and disadvantages.

    Full Text Available An indirect ELISA for determination of post-vaccination rabies antibody was applied. Purified rabies virus was used as antigen to coat plates, and staphylococcal protein A linked with horseradish peroxidase was used for detecting IgG antibody in human sera. Sera from humans, vaccinated with cell-culture vaccine or suckling-mouse-brain vaccine, were examined. ELISA results were compared to those obtained from the virus neutralization test. The mean and standard deviation of OD were determined for 126 negative sera (pre-vaccination and for 73 sera from vaccinated persons showing antibody titers lower than 0.5 IU/ml. Results were defined as ELISA -positive, -negative or -doubtful. Establishment of a doubtful region reduced the number of sera otherwise classified as positive (false-positive sera. In this way, the sensitivity, specificity and agreement values were respectively 87.5%, 92.4% and 88.5%. No significant differences were observed in these values when the group vaccinated with cell-culture vaccine and the group vaccinated with suckling-mouse-brain vaccine were compared. It was shown that much of the disagreement between the values obtained by neutralization test and ELISA occurred in sera obtained at the beginning of the immunization process, and was probably due to the presence of IgM in the serum samples, detected only by the former test. This ELISA method can be used as a screening test in rabies laboratories regardless of the kind of vaccine used for immunization.

    As travellers seek ever more exotic destinations they are more likely to encounter dangerous animals. Compared to risks such as AIDS, traffic accidents and malaria, the risk is not so great; many travellers are, however, concerned about this and those who give pre-travel vaccines and advice should know something about it. This article is mainly based on medical and zoological textbooks. Venomous stings and bites may be prevented by adequate clothing and by keeping safe distance to the animals. Listening to those who live in the area is of course important. Travellers should not carry antisera with them, but antisera should be available at local hospitals. It should be borne in mind that plant eaters cause just as many deaths as large predators. In some cases it is necessary to carry a sufficiently powerful firearm. PMID:12555616

    The development of a new anticancer drug is a long, complex and multistep process which is supervised by regulatory authorities from the different countries all around the world [1]. Application of a new drug for admission to the market is supported by preclinical and clinical data, both including the determination of pharmacodynamics, toxicity, antitumour activity, therapeutic index, etc. As preclinical studies are associated with high cost, optimization of animal experiments is crucial for the overall development of a new anticancer agent. Moreover, in vivo efficacy studies remain a determinant panel for advancement of agents to human trials and thus, require cautious design and interpretation from experimental and ethical point of views.

    As described by Lori Gruen in the Perspective column at the back of this issue, federally supported biomedical research conducted on chimpanzees has now come to an end in the United States, although the wind-down has taken longer than expected. The process began with a 2011 Institute of Medicine report that set up several stringent criteria that sharply limited biomedical research. The National Institutes of Health accepted the recommendations and formed a committee to determine how best to implement them. The immediate question raised by this transition was whether the IOM restrictions should be extended in some form to other nonhuman primates-and beyond them to other kinds of animals. In the lead article in this issue, Anne Barnhill, Steven Joffe, and Franklin Miller consider the status of other nonhuman primates. PMID:27417859

    The aim of commercial pig breeding programs is to maximize the number of pigs produced per sow per year. Given that sows exhibit an estrus during lactation is a potential means of increasing productivity of a pig breeding herd without reducing in lactation length, conventionally, weaning of piglets at a relatively young age is often related to post-weaning piglet performance which compromises piglet welfare. Therefore, intermittent suckling (IS) is a management technique in which lactating sows are separated from their piglets for a fixed period of the days and allowing sows to continue nursing piglets while exhibiting estrus and being breed during lactation, thereby promoting both piglet well-being and sow reproductive performance [1]. For this study, primiparous sows (PP) were exposed to 28 day (D28) lactation with intermittent suckling (IS) during the final week prior to weaning. The sows detected to be in estrus during lactation were either bred at this first estrus (FE) during lactation (IS21FE), or were "skipped" and bred at their second estrus which occurred after final weaning at D28 (IS21SE). Despite the benefits of IS, the effects of the maternal physiology related to breeding during lactation on embryonic transcriptome are largely unknown. Recent advances in the ability to assess embryonic gene expression in both sexes have made these analyses possible. Here, we describe the experimental procedures of two color microarray analyses and annotation of differentially expressed (DE) genes in detail corresponding to data deposited at NCBI in the Gene Expression Omnibus under accession number GSE53576 and GSE73020 for day 9 embryos (D9E) and day 30 embryos (D30E) respectively. Although only a few DE genes were discovered between IS21FE and IS21SE in both sexes from D9E or D30E, the raw data are still valuable for future use to understand the gene expression profiling from two different developmental stages.

  8. Lead induced behavioral dysfunction: an animal model of hyperactivity

    Energy Technology Data Exchange (ETDEWEB)

    Silbergeld, E.K.; Goldberg, A.M.

    1974-01-01

    Although clinically lead poisoning is thought to cause several serious behavioral problems, a causal relationship between lead ingestion and behavioral dysfunction has not been shown. An animal model of lead poisoning was developed in which suckling mice were exposed to lead acetate from birth indirectly through their mothers and then directly after weaning. For the first 60 days, no deaths of offspring occurred due to lead but their growth and development were significantly retarded. Epidemiological evidence exists for the coincidence of lead exposure and hyperactivity syndromes in children. Activity of offspring was measured between 40 and 60 days of age. Treated mice were more than three times as active as agematched controls. Treated and control animals were given drugs used in the treatment and diagnosis of minimal brain dysfunction hyperactivity in children: d- and l-amphetamine, methylphenidate, phenobarbital, and chloral hydrate. Lead-treated hyperactive mice responded paradoxically to all drugs except chloral hydrate: that is, d- and l-amphetamine and methylphenidate suppressed hyperactivity, while phenobarbital increased their levels of motor activity. Chloral hydrate was an effective sedative. Implications of these findings are discussed for the study of the central effects of lead poisoning and for the relationship between lead poisoning and minimal brain dysfunction hyperactivity.

    This study was designed to evaluate in suckling early pregnant beef cows with and without eCG-pre-stimulation: (i) the influence of day gestation (from 40 to 101 days) and the consecutive eCG treatments on the follicular growth induced by means of ultrasound-guided transvaginal follicle ablation (FA; all follicles ≥ 5 mm) and the number and quality oocytes recovered by ovum pick-up (OPU) and (ii) the possible effects of repeated hormonal stimulation and FA/OPU on pregnancy outcome. Twelve suckling early pregnant Angus cows (40 days post fixed-time artificial insemination) were randomly assigned to each of two groups (n=6 group(-1)). Group 1 treatments included: FA (Day 0), eCG (1600 IU; Day 1) and OPU (Day 5). Group 2: as cited Group 1 with no eCG treatment. In both groups, OPU was repeated five times (Days 45, 59, 73, 87 and 101 of gestation). The numbers (mean ± SEM) of class II (5-9 mm; 4.3 ± 0.9) and class III (≥10 mm; 2.5 ± 0.4) follicles visualized per cow per OPU session in eCG-treated cows were greater (P<0.05) than for non-treated cows (0.9 ± 0.1 and 0.9 ± 0.1, respectively). In contrast, the number (mean ± SEM) of class I (<5mm) follicles per cow per OPU session was lower for cows with eCG treatment (2.8 ± 0.4) than for non-treated cows (5.7 ± 0.5). The mean number of aspirated follicles was not significantly different (P<0.05) between eCG-treated cows and non-treated cows at 45 and 59 days of pregnancy. However, the mean number of aspirated follicles was greater (P=0.03) in eCG-treated cows than non-treated cows from 73 day of pregnancy onwards. The numbers (mean ± SEM) of recovered oocytes and viable oocytes/cow/session were greater (P<0.05) for eCG-treated cows (2.2 ± 0.2 and 1.6 ± 0.4, respectively) than for non-treated cows (1.0 ± 0.2 and 0.9 ± 0.2, respectively). No donor pregnancies were lost either during or following OPU procedure. We can conclude that (1) eCG-treated pregnant suckled cows can be a source of oocytes for IVF at

    Primiparous and multiparous suckled Bos indicus × Bos taurus cows were used to compare a Select Synch + controlled internal drug release (CIDR) and timed artificial insemination (AI) protocol (SSC) to a modified CO-Synch + CIDR protocol (COS). Five separate groups of cows were utilized (n = 659) and within a group, cows were allotted to two treatments on the basis of body condition score (BCS) taken 10 days before and days postpartum at CIDR insertion (Day 0). Blood samples were collected on Day -10 and 0 for assessment of circulating concentrations of progesterone to determine estrous cycling status. Cows in both treatments received intramuscular (im) GnRH (100 μg) and a CIDR inserted on Day 0. On Day 7, the SSC treatment had CIDR removed and received im PGF2α (25 mg), whereas COS treatment had CIDR removed and received im PGF2α (25 mg) on Day 7.5. In the SSC treatment, estrus was detected daily at 0700 and 1700 hours for 72 hours after PGF2α administration, and cows were artificially inseminated 8 to 12 hours after a detected estrus. Cows failing to exhibit estrus were subjected to timed-AI and received im GnRH (100 μg) 76 ± 4 hours after PGF2α administration. In the COS treatment, cows received im GnRH (100 μg) and were fixed-time artificially inseminated at 64 ± 4 hours after PGF2α administration. Although group differences (P 0.05) for SSC (49.4%; n = 164 of 332) and COS (47.1%; n = 154 of 327). Estrous cycling status and days postpartum did not (P > 0.05) influence synchronized AI pregnancy rates but BCS did (P < 0.05). Cows with a BCS greater than or equal to 5 had synchronized AI pregnancy rates of 50% compared to 39% for cows with BCS lesser than 5.0. In summary, the modified COS protocol yielded similar synchronized AI pregnancy rates compared to the SSC protocol, and it appears that the modified COS protocol has the potential to be an effective timed-AI protocol in suckled Bos indicus × Bos taurus cows.

    Hundreds of thousands of laboratory animals are being used every year for scientific experiments held in Israel, mostly mice, rats, rabbits, guinea pigs, and a few sheep, cattle, pigs, cats, dogs, and even a few dozen monkeys. In addition to the animals sacrificed to promote scientific research, millions of animals slain every year for other purposes such as meat and fine leather fashion industries. While opening a front against all is an impossible and perhaps an unjustified task, the state of Israel enacted the Animal Welfare (Animal Experimentation) Law (1994). The law aims to regulate scientific animal experiments and to find the appropriate balance between the need to continue to perform animal experiments for the advancement of research and medicine, and at the same time to avoid unnecessary trials and minimize animal suffering. Among other issues the law deals with the phylogenetic scale according to which experimental animals should be selected, experiments for teaching and practicing, and experiments for the cosmetic industry. This article discusses bioethics considerations in animal experiments as well as the criticism on the scientific validity of such experiments. It further deals with the vitality of animal studies and the moral and legal obligation to prevent suffering from laboratory animals. PMID:24660572

    It is found that after administration of 3'-methyl-4-dimethylaminoazobenzene (3'-Me-DAB,) which was hepatocarcinogenic to rats, in suckling mice, the number of neoplastic lesions in the liver of mice was 3 times higher than after analogous administration of equimolar dose of ortho-aminoazotoluene (OAT)). However, in the Ames test (TA-98 strain of Salmonella typhimurium) with activation by hepatic enzymes (S-9 fraction) of both intact and Aroclor-1254-induced mice and rats OAT contributed by an order of magnitude to revertant colonies compared to 3'-Me-DAB. In vivo inhibition of sulfotransferase activity, the enzyme which catalyzes the final stage of the mutagenic activation of aminoazo dyes, had no effect on carcinogenicity of 3'-Me-DAB but more than 4 times elevated that of OAT. It was concluded that the mechanism of carcinogenic action of aminoazo dyes studied is not genotoxic and that the carcinogenic potential of OAT is lost in the process of mutagenic activation.

  3. Failure to demonstrate morphologically the presence of colostral or milk cells in the wall of the gastrointestinal tract of the suckling neonatal mouse

    International Nuclear Information System (INIS)

    The possibility that intact cells may migrate from ingested colostrum and milk into the gut wall of the nursing neonate has been tested directly by means of radioautographic techniques. [3H]Thymidine was continuously infused into female mice throughtout the last 6 days of their pregnancy. Upon delivery, their fully [3H]thymidine-labelled litters were removed and given to nurse from unlabelled surrogate mothers whose own litters were borne simultaneously. These unlabelled litters were similarly removed immediately upon birth and given to the [3H]thymidine-infused mothers to nurse. Infants labelled during gestation and mothers labelled during pregnancy continued to receive thrice-daily injections of isotope for 1-14 days and 1-18 h, respectively, after delivery. The stomach and adjacent portion of small intestine were removed from unlabelled infants nursing from labelled surrogate mothers at intervals of 1-18 h after beginning to suckle, the same tissues were removed from labelled infants nursing from unlabelled surrogate mothers and similarly prepared for radioautography. The results indicate that transepithelial migration of intact cells of the colostrum and milk does not appear to be the method by which immunological functions are adoptively transferred to the nursing neonatal mouse.

  5. Prolonged oral treatment with two monoesters of meso-2,3-dimercaptosuccinic acid for depleting inorganic mercury retention in suckling rats

    International Nuclear Information System (INIS)

    Two monoesters of meso-2,3-dimercaptosuccinic acid (DMSA), monoisoamyl meso-2,3-dimercaptosuccinate (Mi-ADMS) and mono-n-hexyl meso-2,3-dimercaptosuccinate (Mn-HDMS) were compared to DMSA in their efficiency to mobilize 203Hg in mercury-laden suckling rats. Seven-day-old pups were given 203Hg (18.5 kBq) with a dose of 0.5 mg Hg/kg/day as HgCl2 for five days. Seven days after the beginning of Hg loading a ten-day oral treatment with DMSA, Mi-ADMS, or Mn-HDMS was administered at a dose of 0.25 mmol/kg/day. At the end of experiment, radioactivity was measured in the whole body, liver, both kidneys, and brain. Monoesters of DMSA were superior to DMSA in decreasing body and organ Hg retention. The highest reduction in comparison to controls in groups treated with DMSA, Mi-ADMS, or Mn-HDMS occurred in the kidneys (48%, 97%, and 96%), followed by reduction in the liver (24%, 84%, and 83%), and in the brain (8%, 23%, respectively). For both, Mi-ADMS and Mn-HDMS, the reductions in the whole body and organs were significantly greater than in controls or DMSA-treated rats. No difference between the efficiency of the two DMSA-monoesters was found. (au) 20 refs

  6. Growth rate, health and welfare in a dairy herd with natural suckling until 6–8 weeks of age: a case report

    Full Text Available Abstract Over a period of two years, growth rate and health were measured for dairy calves allowed to suckle their mothers up to 6–8 weeks of age. Thirty-one calves were weighted weekly, and the mean daily growth rate was 1.2 ± 0.03 kg from birth up to 13 weeks of age. Illness in calves and young stock was not observed. In the cows, the mean incidences of ketosis, displaced abomasum, puerperal paresis, mastitis, teat injury and retained placenta were 0, 0, 8, 22, 1 and 1%, respectively, during a 6-year period. The mean daily gain of 56 growing bulls was 1.4 kg when slaughtered at 15 months of age, which is higher than the mean daily gain of 0.95 kg in the population. Probiotics, hormones and vaccines were not used, and antibiotics were only used for treating illness. The present study indicates many advantages and few problems when dairy calves are penned together with the cows and allowed natural feeding up to 6–8 weeks of age. This production system was easy to manage, preferred by the farmer, and may satisfy the public concern regarding the practice of immediate separation of cow and calf in commercial milk production.

    2016-01-01

    This article discusses the notion that the invisibility of the animalness of the animal constitutes a fundamental obstacle to change within current production systems. It is discussed whether housing animals in environments that resemble natural habitats could lead to a re-animalization...... of the animals, a higher appreciation of their moral significance, and thereby higher standards of animal welfare. The basic claim is that experiencing the animals in their evolutionary and environmental context would make it harder to objectify animals as mere bioreactors and production systems. It is argued...... that the historic objectification of animals within intensive animal production can only be reversed if animals are given the chance to express themselves as they are and not as we see them through the tunnel visions of economy and quantifiable welfare assessment parameters....

    The use of animals in research will be necessary for scientific advances in the basic and biomedical sciences for the foreseeable future.As we learn more about the ability of animals to experience pain,suffering,and distress,and particularly for mammals,it becomes the responsibility of scientists,institutions,animal caregivers,and veterinarians to seek ways to improve the lives of research animals and refine their care and use.Refinement is one of the three R's emphasized by Russell and Burch,and refers to modification of procedures to minimise the potential for pain,suffering and distress. It may also refer to procedures used to enhance animal comfort. This paper summarizes considerations for refinements in research animal.

    2011-02-01

    Full Text Available Marine animals contain various carotenoids that show structural diversity. These marine animals accumulate carotenoids from foods such as algae and other animals and modify them through metabolic reactions. Many of the carotenoids present in marine animals are metabolites of β-carotene, fucoxanthin, peridinin, diatoxanthin, alloxanthin, and astaxanthin, etc. Carotenoids found in these animals provide the food chain as well as metabolic pathways. In the present review, I will describe marine animal carotenoids from natural product chemistry, metabolism, food chain, and chemosystematic viewpoints, and also describe new structural carotenoids isolated from marine animals over the last decade.

    Köhler, B; Zabke, J; Sondermann, R; Pulst, H; Rummler, H J

    1979-01-01

    Necrotising enteritis had been the cause of death of 4.9 per cent in 5,177 nursed piglets, which was established by pathological examination. The number of piglets, in that context, which had come from industrialised sow breeding units was equivalent to 92 per cent. The nursed piglet held the third position, next to smaller ruminants (19.4 per cent) and fowl (6.0 per cent), with regard to the occurrence of Clostridium perfringens enterotoxemia or necrotising enteritis in 112,218 animals which were pathologically examined after death. Necrotising enteritis so far has been rare in the GDR. No regional accumulation has been observed. Several outbreaks on industrialised sow breeding units actually remained stationary. The occurrence of the disease may be favoured by a number of factors which are conducive to accumulation of Clostridium perfringens Type C in a given stock. Group keeping of pregnant sows, simultaneous farrowing of larger groups of sows, group treatment of nursed piglets, using neomycin, chloramphenicol, oxytetracycline, and other antibiotics to which Clostridium perfringens is primarily resistant or has acquired resistance in the course of time are some of those contributive factors. Transmission of Clostridium perfringens Type C through feedstuff is possible, though it would lead to a real outbreak only by high intensity of the contamination, and it played a minor role in proliferation of the disease. 3479 Clostridium perfringens strains were isolated from 9,481 animals, both clinically intact and after death, with 30 species being included. Type classification revealed 2454 strains of Type A (70 per cent), 204 of Type D (5.88 per cent), 164 of Type C (four per cent), and 48 of Type B (1.34 per cent). There were 688 atoxic strains (17 per cent). Swine is the major carrier of Clostridium perfringens Type C, with 87 per cent of all Clostridium perfringens Type C strains having been isolated from swine. Swine was followed by fowl (four per cent), sheep

Thus the apparent descriptions of the animals are really the deep revelations of the human beings. Animal Farm is one exemplary product of this special expressing way. Diversified animal images are intelligently used by George Orwell to represent the people, so all the characters are animals in appearance, but humans in nature. Starting from the animal images and then the conceptual metaphors, readers can perceive a fresh understanding of this classical book. In this novel, three conceptual metaphors are identified and the special findings can be illustrated as the following: Firstly, the whole story of the animals represents the history and politics of the Soviet Union. Secondly, the pigs symbolize the authorities of the society. Thirdly, the names of the characters in the novel reveal their identities.

    1990-05-01

    Two trials were conducted in which Angus x Hereford first-calf cows were assigned randomly at calving to one of two treatments: exposure to mature penile-blocked bulls (BE) or isolation from bulls (NE). In Trial 1 (BE, n = 38; NE, n = 37), cow to bull ratio increased from 12:1 to 19:1 over a 14-d period; in Trial 2 (BE, n = 25; NE, n = 24), this ratio was maintained at 13:1. In both trials, blood samples were collected weekly for progesterone and ovaries and uteri of cows were examined rectally. Cows were observed for estrus twice daily (am:pm) beginning 10 d after calving. In Trial 2, intensive blood sampling for LH began 10 d after calving (eight cows per treatment) and continued at weekly intervals until estrus or the end of the trial. Postpartum weight change, condition score change and time to uterine involution did not differ (P greater than .10) between treatments in either trial. Interval to estrus was shorter (P less than .05) for BE cows than for NE cows in both trials. A greater proportion (P less than .05) of BE cows exhibited estrus by 60 and 90 d after calving and showed an increase in progesterone before first estrus. Mean and baseline LH concentrations and amplitude, frequency and duration of LH pulses were not altered (P greater than .10) by bull exposure. In conclusion, exposing first-calf suckled beef cows to bulls after calving hastened resumption of estrous cycles. Bull exposure did not alter patterns of LH concentrations but did increase proportions of cows that showed increased progesterone before first estrus. PMID:2365649

    The objective was to determine the effect of sequence of insemination after simultaneous thawing of multiple 0.5 mL semen straws on conception rate in suckled multiparous Nelore cows. The effect of this thawing procedure on in vitro sperm characteristics was also evaluated. All cows (N = 944) received the same timed AI protocol. Ten straws (0.5 mL) of frozen semen from the same batch were simultaneously thawed at 36 °C, for a minimum of 30 sec. One straw per cow was used for timed AI. Frozen semen from three Angus bulls was used. Timed AI records included sequence of insemination (first to tenth) and time of semen removal from thawing bath. For laboratory analyses, the same semen batches used in the field experiment were evaluated. Ten frozen straws from the same batch were thawed simultaneously in a thawing unit identical to that used in the field experiment. The following sperm characteristics were analyzed: sperm motility parameters, sperm thermal resistance, plasma and acrosomal membrane integrity, lipid peroxidation, chromatin structure, and sperm morphometry. Based on logistic regression, there were no significant effects of breeding group, body condition score, AI technician, and sire on conception rate, but there was an interaction between sire and straw group (P = 0.002). Semen from only one bull had decreased (P < 0.05) field fertility for the group of straws associated with the longest interval from thawing to AI. However, the results of the laboratory experiment were unable to explain the findings of the field experiment. Sperm width:length ratio of morphometric analysis was the single sperm characteristic with a significant interaction between sire and straw group (P = 0.02). It was concluded that sequence of insemination after simultaneous thawing of 10 semen straws can differently affect conception rates at timed AI, depending on the sire used. Nevertheless, the effects of this thawing environment on in vitro sperm characteristics, remain to be

    The objective of this study was to evaluate the effect of an extended progesterone treatment on follicular development and fertility in postpartum, suckled beef cows subjected to timed artificial insemination (TAI). In experiment 1, cows (n = 24) with body condition score (BCS) ≥4.5 received either a 2-g progesterone intravaginal device on Day -23 or a 0.558-g progesterone intravaginal device on Day -9. Then, all cows received 2 mg of estradiol benzoate on Day -9; removal of the device, 1-mg estradiol cypionate, and PGF2α on Day -2; and TAI on Day 0. Metabolic status was assessed between Days -9 and -2. Ovarian structures and plasma progesterone were determined weekly from Day -23 to -9, daily from Day -9 to 0, and weekly until Day 28. In experiment 2, cows (n = 302) with BCS ≥4.5 received identical treatment to cows in experiment 1, but on Day -2, cows received 400 IU of two different commercial preparations of equine chorionic gonadotropin (eCG). Ovarian structures were determined on Days -23 and -9 on a subset of cows (n = 40). Pregnancy was determined 39 days after TAI. In experiment 3, multiparous cows (n = 244) with BCS AI. In experiment 3, extended progesterone treatment combined with eCG increased the size of the dominant follicle (P = 0.01). Both extended progesterone treatment (P = 0.02) and eCG (P = 0.03) increased pregnancy per AI. In conclusion, an extended progesterone treatment stimulated follicular growth postpartum and improved fertility only in cows with low BCS. PMID:26944539

    Fecal samples obtained from wild boar habitats are useful for the surveillance of diseases in wild boar populations; however, it is difficult to determine the species of origin of feces collected in natural habitats. In this study, a fecal IgA ELISA was evaluated as a method for identifying the porcine species from fecal samples. Both domestic pigs (Sus scrofa domestica) and wild boars (Sus scrofa coreanus) showed significantly higher levels of fecal IgA than other animal species. Additionally, age dependent changes in the level of Ig A in wild boars and domestic pigs were identified; Titers of Ig A were highest in suckling period and lowest in weanling period. PMID:27340389

  9. Biological half-life of xenobiotic bromide in the rat is dependent on sodium intake and varies with the metabolic activity of the animals

    International Nuclear Information System (INIS)

    In the present study, we extended the applicability of our experimentally proved hypothesis. In the rats situated in very different physiological states, as regards their metabolic activity, we investigated variations in the biological half-life of bromide (as a substitute for sodium) with the aid of in vivo whole-body counting of the animals, administered simultaneously with the radionuclides 82Br and 24Na, by high-resolution gamma-ray spectrometry. The excretion rates of bromide were measured in animals situated in different physiological states. The shortest biological half-life of bromide/sodium ions (44 h) was determined in lactating dams and the longest (269 h) in breast-fed pups. The measured values demonstrate that lactating dams obviously waste sodium, due to their large food intake, whereas sucklings apparently conserve sodium, because of its relatively low concentration in breast milk.

    Full Text Available Animism is often described as the imputation of life to inert objects. Such imputation is more typical of people in western societies who dream of finding life on other planets than of indigenous peoples to whom the label of animism has classically been applied. These peoples are united not in their beliefs but in a way of being that is alive and open to a world in continuous birth. In this animic ontology, beings do not propel themselves across a ready-made world but rather issue forth through a world-in-formation, along the lines of their relationships. To its inhabitants this weather-world, embracing both sky and earth, is a source of astonishment but not surprise. Re-animating the ‘western’ tradition of thought means recovering the sense of astonishment banished from offi cial science.

  3. Animal Models for imaging

    OpenAIRE

    Croft, Barbara Y.

    2002-01-01

    Animal models can be used in the study of disease. This chapter discusses imaging animal models to elucidate the process of human disease. The mouse is used as the primary model. Though this choice simplifies many research choices, it necessitates compromises for in vivo imaging. In the future, we can expect improvements in both animal models and imaging techniques.

  8. High-affinity glutamate transporter and glutamine synthetase content in longissimus dorsi and adipose tissues of growing Angus steers differs among suckling, weanling, backgrounding, and finishing production stages.

    2016-03-01

    Skeletal muscle and adipose tissues play important roles in maintaining whole-body Glu and N homeostasis by the uptake of Glu and release of Gln. To test the hypothesis that expression of high-affinity Glu transporters (GLAST1, EAAT4, EAAC1, GLT-1) and glutamine synthetase (GS) would increase in longissimus dorsi and adipose tissue of newborn Angus steers randomly assigned ( = 6) to develop through suckling (S; 32 d) and/or weanling (W; 184 d), backgrounding (B; 248 d), and finishing (F; 423 d) production stages. Carcass quality was determined at slaughter to verify shifts in adipose and lean deposition with development. Expression of mRNA (RT-PCR/Southern) and relative protein abundance (Western analysis) were determined in tissue homogenates isolated from longissimus dorsi, and kidney and subcutaneous adipose. The effect of production stage or tissue type on carcass and protein abundance was assessed by 1-way ANOVA using the GLM procedure of SAS, and Fisher's protected LSD procedure was used to separate data means. Neither GLAST1 nor EAAT4 mRNA or protein was detected. EAAC1, GLT-1, and GS mRNA were identified in all tissues, but GLT-1 and GS protein were not detected in kidney or subcutaneous adipose, and GS protein was not detected in longissimus dorsi. The EAAC1 content of subcutaneous ( = 0.06) and kidney ( = 0.02) adipose was 2 times greater in B and F than W steers, whereas GS was 5 times greater ( F). For longissimus dorsi, EAAC1 ( W > B = F, S = W > B = F, respectively). Within F steers, EAAC1 and GLT-1 mRNA was expressed by subcutaneous, kidney, omental, mesenchymal, and intramuscular adipose tissues, whereas GS mRNA was expressed by all except for intramuscular. Only EAAC1 protein was detected in any adipose tissue, with EAAC1 content being 104% and 112% greater ( 0.45) from omental or mesenchymal adipose. These data demonstrate (1) longissimus dorsi and adipose tissues of steers developing through typical production stages have different capacities for

  10. Small Animal Retinal Imaging

    Science.gov (United States)

    Choi, WooJhon; Drexler, Wolfgang; Fujimoto, James G.

    Developing and validating new techniques and methods for small animal imaging is an important research area because there are many small animal models of retinal diseases such as diabetic retinopathy, age-related macular degeneration, and glaucoma [1-6]. Because the retina is a multilayered structure with distinct abnormalities occurring in different intraretinal layers at different stages of disease progression, there is a need for imaging techniques that enable visualization of these layers individually at different time points. Although postmortem histology and ultrastructural analysis can be performed for investigating microscopic changes in the retina in small animal models, this requires sacrificing animals, which makes repeated assessment of the same animal at different time points impossible and increases the number of animals required. Furthermore, some retinal processes such as neurovascular coupling cannot be fully characterized postmortem.

  11. Animals as disgust elicitors

    DEFF Research Database (Denmark)

    Kasperbauer, Tyler Joshua

    2015-01-01

    This paper attempts to explain how and why nonhuman animals elicit disgust in human beings. I argue that animals elicit disgust in two ways. One is by triggering disease–protection mechanisms, and the other is by eliciting mortality salience, or thoughts of death. I discuss how these two types...... of disgust operate and defend their conceptual and theoretical coherence against common objections. I also outline an explanatory challenge for disgust researchers. Both types of disgust indicate that a wide variety of animals produce aversive and avoidant reactions in human beings. This seems somewhat odd......, given the prominence of animals in human lives. The challenge, then, is explaining how humans cope with the presence of animals. I propose, as a hypothesis for further exploration, that we cope with animals, and our disgust responses to them, by attributing mental states that mark them as inferior...

The females, with age between two and six years, were randomly distributed in three groups (GI, GII, GIII. The females of GI (n = 30 received 250µg of PGF2α in vulvar muscle on days 6th and 12th after delivery. The females of GII (n = 30 received the same treatment of Group I, but every day from days 6th to 10th after delivery. The GIII (n = 20 was the control group. The estrous detection was made by using teasers and the mating with bucks with confirmed fertility. The obtained data were analyzed by ANOVA and by analysis of standard errors of difference among proportions. Difference in the occurrence of estrous among the three experimental groups was not observed (P > 0.05, however the average time of post partum anestrous was significantly reduced (P < 0.05 in animals treated with PGF2α. It was also detected a relevant reduction (P < 0.05 of post-partum anestrous in females with controlled suckled. Difference was not registered (P > 0.05 on pregnant percentages among the different groups. It may be concluded that the administration of PGF in the beginning of puerperium in caprine is efficient to reduce the anestrous pos-partum period, specially in females controlled suckled; however do not influence the fertility in meat goats.

  16. Interaction between animal personality and animal cognition

    Directory of Open Access Journals (Sweden)

    Claudio CARERE, Charles LOCURTO

    2011-08-01

    Full Text Available The study of animal personality has attracted considerable attention, as it has revealed a number of similarities in personality between humans and several nonhuman species. At the same time the adaptive value and evolutionary maintenance of different personalities are the subject of debate. Since Pavlov’s work on dogs, students of comparative cognition have been aware that animals display vast individual differences on cognitive tasks, and that these differences may not be entirely accounted for differences in cognitive abilities. Here, we argue that personality is an important source of variation that may affect cognitive performance and we hypothesise mutual influences between personality and cognition across an individual’s lifespan. In particular, we suggest that: 1 personality profiles may be markers of different cognitive styles; 2 success or failure in cognitive tasks could affect different personalities differently; 3 ontogenetic changes of personality profiles could be reflected in changes in cognitive performance. The study of such interplay has implications in animal welfare as well as in neuroscience and in translational medicine [Current Zoology 57 (4: 491–498, 2011].

  17. Animal Health in Albania

    International Nuclear Information System (INIS)

    The animal health service policy in Albania represents an integral component of overall governmental, social and economic policy in the field of agricultural and rural development, public health, food processing and import/export of animal products. In order to obtain the necessary political, economic and public support, the animal health service attempts to contribute effectively to the overall development of the country which aims at improving the standards of living of its inhabitants. Practical means of contributing to national development include reducing food loses due to animal morbidity and mortality, increasing the productivity of the livestock population, protecting human health against zoonotic diseases and ensuring humane treatment of animals. An animal health strategy contributes to the creation of conditions necessary for uninterrupted animal disease surveillance and control in the country. The main animal health problem in Albania is brucellosis in ruminants, caused by B. melitensis. This infection currently affects the entire country, reaching a prevalence of 10% in several districts. The latest and most severe outbreaks of classical swine fever were identified on 1996 when 5 515 animals were infected and 3 683 animals died. The circulation of bluetongue virus (BTV) was detected for the first time in Albania in 2002 with a seroprevalence of 15%. The evidence of BTV circulation in Albania and the absence of the main vector C. imicola suggest that other Culicoides species could be implicated in virus transmission. H5N1 avian influenza in Albania was confirmed in March 2006 in backyard flocks in the villages of Cuke and Peze-Helmes. In both villages there were no human cases. Rabies was of concern in Albania from 1928 until 1976. The disease re-emerged in March 2001 in the village of Morine in Kukes district affecting a domestic dog and three persons were bitten. Other cases have been reported in northern Albania. (author)

    The use of alternative methods to animal testing are an integral part of the 3Rs concept (refine, reduce, replace) defined by Russel & Burch in 1959. These approaches include in silico methods (databases and computer models), in vitro physicochemical analysis, biological methods using bacteria or isolated cells, reconstructed enzyme systems, and reconstructed tissues. Emerging "omic" methods used in integrated approaches further help to reduce animal use, while stem cells offer promising approaches to toxicologic and pathophysiologic studies, along with organotypic cultures and bio-artificial organs. Only a few alternative methods can so far be used in stand-alone tests as substitutes for animal testing. The best way to use these methods is to integrate them in tiered testing strategies (ITS), in which animals are only used as a last resort. PMID:20669543

    Translational research plays a vital role in understanding the underlying pathophysiology of human diseases, and hence development of new diagnostic and therapeutic options for their management. After creating an animal disease model, pathophysiologic changes and effects of a therapeutic intervention on them are often evaluated on the animals using immunohistologic or imaging techniques. In contrast to the immunohistologic techniques, the imaging techniques are noninvasive and hence can be us...

    Nowadays it is common to talk about metaphor. In fact, metaphor is a kind of comparison. Because of comparison and association,familiar objects become strange and glamorous. Animal metaphors can involve either nominal form or verb forms. A person's crying may be called barking. A woman may be called a cat, or a goose, etc. Animal metaphor is connected tightly with our life and helps language development. We can utilize them to make our life and languages more colorful.

  1. Animal models of ADHD.

    Bari, A; Robbins, T W

    2011-01-01

    Studies employing animal models of attention-deficit/hyperactivity disorder (ADHD) present clear inherent advantages over human studies. Animal models are invaluable tools for the study of underlying neurochemical, neuropathological and genetic alterations that cause ADHD, because they allow relatively fast, rigorous hypothesis testing and invasive manipulations as well as selective breeding. Moreover, especially for ADHD, animal models with good predictive validity would allow the assessment of potential new therapeutics. In this chapter, we describe and comment on the most frequently used animal models of ADHD that have been created by genetic, neurochemical and physical alterations in rodents. We then discuss that an emerging and promising direction of the field is the analysis of individual behavioural differences among a normal population of animals. Subjects presenting extreme characteristics related to ADHD can be studied, thereby avoiding some of the problems that are found in other models, such as functional recovery and unnecessary assumptions about aetiology. This approach is justified by the theoretical need to consider human ADHD as the extreme part of a spectrum of characteristics that are distributed normally in the general population, as opposed to the predominant view of ADHD as a separate pathological category.

    International Nuclear Information System (INIS)

    The Animal Ecology project is an integral part of the terrestrial ecology program. For convenience, it is reported separately because of the specialized nature of its techniques. It includes studies to characterize faunal populations taxonomically and ecologically and to estimate density and biomass of important mammal, bird, herpetofauna, and invertebrate populations. Extensive studies of small mammal populations conducted in past years are being summarized for open literature publication. Methodology and techniques developed in the animal ecology program are expected to be vital to studies to be initiated under a newly funded 189 entitled Radioecology of Waste Management Zones. These kinds of supportive studies will be needed to determine dietary habits of important animals inhabiting waste management zones, construction of realistic food chain models, and estimating radioactivity doses to biota

    2005-07-01

    The scaling behavior of randomly branched polymers in a good solvent is studied in two to nine dimensions, modeled by lattice animals on simple hypercubic lattices. For the simulations, we use a biased sequential sampling algorithm with re-sampling, similar to the pruned-enriched Rosenbluth method (PERM) used extensively for linear polymers. We obtain high statistics of animals with up to several thousand sites in all dimension 2⩽d⩽9. The partition sum (number of different animals) and gyration radii are estimated. In all dimensions we verify the Parisi-Sourlas prediction, and we verify all exactly known critical exponents in dimensions 2, 3, 4, and ⩾8. In addition, we present the hitherto most precise estimates for growth constants in d⩾3. For clusters with one site attached to an attractive surface, we verify the superuniversality of the cross-over exponent at the adsorption transition predicted by Janssen and Lyssy.

The animation shows how the lidar is activated by first opening its dust cover, then emitting rapid pulses of light (resembling a brilliant green laser) into the Martian atmosphere. Some of the light then bounces off particles in the atmosphere, and is reflected back down to the lidar's telescope. This allows the lidar to detect dust, clouds and fog.

  7. Companion animal adoption study.

    Science.gov (United States)

    Neidhart, Laura; Boyd, Renee

    2002-01-01

    To better understand the outcomes of companion animal adoptions, Bardsley & Neidhart Inc. conducted a series of 3 surveys over a 1-year period with dog and cat owners who had adopted their pet through either a (a) Luv-A-Pet location, (b) Adopt-a-thon, or (c) traditional shelter. This article suggests opportunities to improve owners' perceptions of their pets and the adoption process through (a) providing more information before adoption about pet health and behaviors, (b) providing counseling to potential adopters to place pets appropriately, and (c) educating adopters to promote companion animal health and retention. Results demonstrate that the pet's relationship to the family unit, such as where the pet sleeps and how much time is spent with the pet, is related to the amount of veterinary care the companion animal receives, and to long-term retention. Satisfaction and retention are attributed to the pet's personality, compatibility, and behavior, rather than demographic differences among adopters or between adoption settings. The age of the companion animal at adoption, the intended recipient, and presence of children in the home also play a role. Health problems were an issue initially for half of all adopted pets, but most were resolved within 12 months. Roughly one fourth of adopters who no longer have their companion animal said their pet died. Characteristics of pets that died support the contention that spaying and neutering profoundly affects a companion animal's life span. Although retention is similar for dogs and cats, mortality is higher among cats in the first year after adoption. PMID:12578739

  8. Animal violence demystified

    Directory of Open Access Journals (Sweden)

    Deepa Natarajan

    2010-04-01

    Full Text Available Violence has been observed in humans and animals alike, indicating its evolutionary/ biological significance. However, violence in animals has often been confounded with functional forms of aggressive behavior. Currently, violence in animals is identified primarily as either a quantitative behavior (an escalated, pathological and abnormal form of aggression characterized primarily by short attack latencies, and prolonged and frequent harm-oriented conflict behaviors or a qualitative one (characterized by attack bites aimed at vulnerable parts of the opponent’s body and context independent attacks regardless of the environment or the sex and type of the opponent. Identification of an operational definition for violence thus not only helps in understanding its potential differences from adaptive forms of aggression but also in the selection of appropriate animal models for both. To begin with, we address this issue theoretically by drawing parallels from research on aggression and appeasement in humans and other animals. We also provide empirical evidences for violence in mice selected for high aggression by comparing our findings with other currently available potentially violent rodent models. The following violence-specific features namely 1. Display of low levels of pre-escalatory/ritualistic behaviors. 2. Immediate and escalated offense durations with low withdrawal rates despite the opponent’s submissive supine and crouching/defeat postures. 3. Context independent indiscriminate attacks aimed at familiar/unfamiliar females, anaesthetized males and opponents and in neutral environments. 4. Orientation of attack-bites toward vulnerable body parts of the opponent resulting in severe wounding 5. Low pre-frontal serotonin (5-HT levels upon repeated aggression. 6. Low basal heart rates and hyporesponsive hypothalamus-pituitary-adrenocortical (HPA axis were identified uniquely in the short attack latency (SAL mice suggesting a qualitative

  11. Animal models of tinnitus.

    Science.gov (United States)

    Brozoski, Thomas J; Bauer, Carol A

    2016-08-01

    Presented is a thematic review of animal tinnitus models from a functional perspective. Chronic tinnitus is a persistent subjective sound sensation, emergent typically after hearing loss. Although the sensation is experientially simple, it appears to have central a nervous system substrate of unexpected complexity that includes areas outside of those classically defined as auditory. Over the past 27 years animal models have significantly contributed to understanding tinnitus' complex neurophysiology. In that time, a diversity of models have been developed, each with its own strengths and limitations. None has clearly become a standard. Animal models trace their origin to the 1988 experiments of Jastreboff and colleagues. All subsequent models derive some of their features from those experiments. Common features include behavior-dependent psychophysical determination, acoustic conditions that contrast objective sound and silence, and inclusion of at least one normal-hearing control group. In the present review, animal models have been categorized as either interrogative or reflexive. Interrogative models use emitted behavior under voluntary control to indicate hearing. An example would be pressing a lever to obtain food in the presence of a particular sound. In this type of model animals are interrogated about their auditory sensations, analogous to asking a patient, "What do you hear?" These models require at least some training and motivation management, and reflect the perception of tinnitus. Reflexive models, in contrast, employ acoustic modulation of an auditory reflex, such as the acoustic startle response. An unexpected loud sound will elicit a reflexive motor response from many species, including humans. Although involuntary, acoustic startle can be modified by a lower-level preceding event, including a silent sound gap. Sound-gap modulation of acoustic startle appears to discriminate tinnitus in animals as well as humans, and requires no training or

Indeed, it can be used to select reproducers free chromosome abnormalities which are responsible for abnormal body conformation (aneuploidy, lower fertility (balanced chromosome abnormalities or sterility (sex chromosome abnormalities. Cytogenetics may also be applied to assess environmental pollution by studying animals living in hazardous areas and using them as biological indicators (sentinels. Chromosomes also represent optimal biological structures to study the evolution among related (bovids and unrelated (bovidshumans species, especially using comparative FISH-mapping which is one of the most powerful tools to establish the correct order of loci along chromosomes. These comparisons allow us to transfer useful information from richer genomes (human to those of domestic animals. Moreover, the use of specific molecular markers and the FISH-technique on both mitotic and extended (fiber-FISH chromosomes, has heralded a new era of cytogenetics, allowing swift extension of genetic physical maps, better anchoring of both linkage and RH-maps to specific chromosome regions, and use in a variety of applications (clinical cases, embryo and sperm analyses, evolution.

    Animal rights activists demonstrated against physicians in Pittsburgh, Pennsylvania, who had transplanted a baboon liver into a man. They complained that baboons should not serve as spare parts for humans, but the complaint misfired when another man with liver disease challenged them. Nevertheless the rapidly growing population in the world is threatening animal species such as elephants. In Zimbabwe where a severe drought exists and which has been somewhat able to protect animals from poachers, the government now allows people to kill elephants and other animals for their meat. The great numbers of wildlife have placed considerable population pressure on Gonarezhou National Park. The government hopes the good will plan will reduce the number of illegal poachings in the future. This illustrates the need for population stability to protect the environment. Yet the 1992 UN environment conference in Rio de Janeiro, Brazil, did not address population growth as a threat to biodiversity and the environment. Indeed if population continues to grow at its present rate, the population in 2100 will stand at 19 billion and each year before that the Earth will lose more farmland and forests and witness more days of smog, polluted water, political instabilities, and environmental refugees. Viruses like HIV may afflict the population. Most of the population growth will be in developing countries where drought and economic and political instabilities are common. In 2100 with such a hugh population, a national park for wildlife will most likely only be a luxury. We can no longer be complacent and must take action now to prevent this disaster. It will soon be clear that a growing population does not produce more prosperity as many economists would like us to believe, and discussions about using animals for spare parts will be ludicrous.

    2012-04-01

    Many gaits of four-legged animals are described by symmetry. For example, when a horse paces it moves both left legs in unison and then both right legs and so on. The motion is described by two symmetries: Interchange front and back legs, and swap left and right legs with a half-period phase shift. Biologists postulate the existence of a central pattern generator (CPG) in the neuronal system that sends periodic signals to the legs. CPGs can be thought of as electrical circuits that produce periodic signals and can be modeled by systems with symmetry. In this lecture we discuss animal gaits; use gait symmetries to construct a simplest CPG architecture that naturally produces quadrupedal gait rhythms; and make several testable predictions about gaits.

    Full Text Available The aim of this paper is to contribute to answering the conceptual question whether there can be weak-willed non-human animals. After some preliminary clarifications concerning the phenomenon of weakness of will three different accounts are examined for the conditions a being has to fulfill in order to be in a position to display weakness of will. It is argued that these conditions are very strong and that there are good reasons to assume that, e.g., only language users can be weak-willed. This is taken as an independent argument for Davidson's thesis that non-human animals which are not language users cannot act intentionally.

Using a three-week long innovation workshop, U- CrAc, involving 16 Danish companies and organisations and 142 students as empirical data, we discuss how animation-based sketching can explore not yet existing user...... both apathetic and sympathetic views, the ethical reflections are more nuanced as a result of actually seeing the user experience simulated through different user dispositions. Exploring the three ethical stances by visualising real use cases with the technologies simulated as already being implemented...

    The objective was to study Orthomyxovirus in heterothermic animals. Blood samples from snakes (genus Bothrops and Crotalus) and from toads and frogs (genus Bufo and Rana) were collected to evaluate the red cell receptors and antibodies specific to influenza virus by the hemagglutination and hemagglutination inhibition tests, respectively. Both snakes and toads kept in captivity presented receptors in their red cells and antibodies specific to either influenza virus type A (human and equine origin) or influenza type B. The same was observed with recently captured snakes. Concerning the influenza hemagglutination inhibition antibodies protective levels were observed in the reptiles' serum, against influenza type A and type B. Unlike the toads, 83.3% of the frogs presented mean levels of Ab 40HIU for some influenza strains. It was concluded that heterothermic animals could offer host conditions to the influenza virus and also susceptibility to the infection. PMID:15330057

    Porter, W P; Ostrowski, S; Williams, J B

    2010-01-01

    There is an increasing need to assess the effects of climate and land-use change on habitat quality, ideally from a mechanistic basis. The symposium "Molecules to Migration: Pressures of Life" at the Fourth International Conference in Africa for Comparative Physiology and Biochemistry, Maasai Mara National Reserve, Kenya, 2008, illustrated how the principles of biophysical ecology can capture the mechanistic links between organisms, climate, and other habitat features. These principles provide spatially explicit assessments of habitat quality from a physiological perspective (i.e., "animal landscapes") that can be validated independently of the data used to derive and parameterize them. The contents of this symposium showcased how the modeling of animal landscapes can be used to assess key issues in applied and theoretical ecology. The presentations included applications to amphibians, reptiles, birds, and mammals. The rare Arabian oryx on the Arabian Peninsula is used as an example for energetic calculations and their implications for behavior on the landscape. PMID:20670170

    The recent interest of the government of Ghana in agricultural mechanization has largely focused on the provision of tractors and imported machinery to the farming population. Animal traction has not received much attention from the country’s policymakers. The strong demand for mechanization services (Houssou et al., 2012; Benin et al., 2012) and inadequate number of tractors to meet the demand in the country call for more effective use of other power sources for the agriculture sector.

    Atherosclerosis is a chronic inflammatory disorder that is the underlying cause of most cardiovascular disease. Both cells of the vessel wall and cells of the immune system participate in atherogenesis. This process is heavily influenced by plasma lipoproteins, genetics and the hemodynamics of the blood flow in the artery. A variety of small and large animal models have been used to study the atherogenic process. No model is ideal as each has its own advantages and limitations with respect to...

    Metacognition is thinking about thinking. There is considerable interest in developing animal models of metacognition to provide insight about the evolution of mind and a basis for investigating neurobiological mechanisms of cognitive impairments in people. Formal modeling of low-level (i.e., alternative) mechanisms has recently demonstrated that prevailing standards for documenting metacognition are inadequate. Indeed, low-level mechanisms are sufficient to explain data from existing methods...

Good animal welfare means that consideration has been given to the animals' biology and subjective experience and to its possibilities to adapt to the ...

  11. Transfer to animals

    International Nuclear Information System (INIS)

    Data have been compiled to derive animal product transfer coefficients for radionuclides to update the values given in Technical Reports Series No. 364. Significant new data inputs have been incorporated from an extensive review of Russian language information and inclusion of data published since the early 1990s. The resultant database has been used to provide reference transfer coefficient values for a range of radionuclides to (i) cow, sheep and goat milk, (ii) meat (muscle) of cattle, sheep, goats, pigs and poultry and (iii) eggs. The approaches and procedures used to identify and collate data, and assumptions used are given. For most animal products, transfer coefficient values for elements additional to those in Technical Reports Series No. 364 are provided, although some elements were considered in the earlier evaluation which were not included in this review. Differences between the Technical Reports Series No. 364 'expected' values and the reference values from this document, which will be incorporated into the revised transfer parameter handbook, are discussed. An alternative approach to quantifying transfer by using concentration ratios is evaluated and CR values which could be applied across animal species have been provided for milk and meat. Information on fractional gastrointestinal absorption in adult ruminants has been compiled and reference values presented. Despite these improvements many data gaps remain. (author)

  12. History of animal bioacoustics

    Science.gov (United States)

    Popper, Arthur N.; Dooling, Robert J.

    2002-11-01

    The earliest studies on animal bioacoustics dealt largely with descriptions of sounds. Only later did they address issues of detection, discrimination, and categorization of complex communication sounds. This literature grew substantially over the last century. Using the Journal of the Acoustical Society of America as an example, the number of papers that fall broadly within the realm of animal sound production, communication, and hearing rose from two in the partial first decade of the journal in the 1930's, to 20 in the 1970's, to 92 in the first 2 years of this millennium. During this time there has been a great increase in the diversity of species studied, the sophistication of the methods used, and the complexity of the questions addressed. As an example, the first papers in JASA focused on a guinea pig and a bird. In contrast, since the year 2000 studies are often highly comparative and include fish, birds, dolphins, dogs, ants, crickets, and snapping shrimp. This paper on the history of animal bioacoustics will consider trends in work over the decades and discuss the formative work of a number of investigators who have spurred the field by making critical theoretical and experimental observations.

  13. ADVANCES IN ANIMAL WELFARE FOR FREE-LIVING ANIMALS.

    Science.gov (United States)

    2016-04-01

    Over several decades, animal welfare has grown into its own free-standing field of scientific study, from its early beginnings in laboratory animal research to eventually include exhibited animals and farm animals. While it has always been present to some degree, consideration of animal welfare for free-ranging animals has lagged behind, developing as a field of study in the last 20 yr or so. Part of that increase was that animal welfare legislation was finally applied to studies being done on free-ranging animals. But it is the appreciation by the biologists and veterinarians working on wild animals, in which the quality of their results is largely controlled by the quality of the animals they use in their studies, which has resulted in increased attention to the well-being or welfare of the animals that they use. Other important influences driving the recognition of wildlife welfare have been changes in the public's expectations of how wild animals are dealt with, a shift in focus of wildlife professionals from managing animals that can be hunted or angled to include nongame species, the decrease in participation in hunting and fishing by members of the public, and the entry of large numbers of women into fish and wildlife agencies and departments and into veterinary medicine. Technical improvements have allowed the safe capture and handling of large or dangerous animals as immobilization drugs and equipment have been developed. The increasing use of sedating drugs allows for handling of animals with reduced stress and other impacts. A number of topics, such as toe-clipping, branding, defining which taxa can or cannot feel pain, catch-and-release fishing, and more, remain controversial within wildlife science. How we treat the wild animals that we deal with defines who we are as wildlife professionals, and animal welfare concerns and techniques for free-ranging animals will continue to develop and evolve.

In ruminants, 70 % of protein requirement is satisfied by cytoplasmic synthesised protein, while the remaining 30 % is provided by the regular diet. In juvenile animals, when the rumen is not completely developed (Donkin et al., 1987; Thaler et al., 1992, bacterial proteins are not sufficient to satisfy the protein requirements. Naturally available sheep diet is deficient in the proteins required and contributes to low efficiency in protein utilisation in these species (Corino et al., 1995; Rossi et al., 1991...

    Full Text Available The field of mitochondrial DNA (mtDNA replication has been experiencing incredible progress in recent years, and yet little is certain about the mechanism(s used by animal cells to replicate this plasmid-like genome. The long-standing strand-displacement model of mammalian mtDNA replication (for which single-stranded DNA intermediates are a hallmark has been intensively challenged by a new set of data, which suggests that replication proceeds via coupled leading-and lagging-strand synthesis (resembling bacterial genome replication and/or via long stretches of RNA intermediates laid on the mtDNA lagging-strand (the so called RITOLS. The set of proteins required for mtDNA replication is small and includes the catalytic and accessory subunits of DNA polymerase y, the mtDNA helicase Twinkle, the mitochondrial single-stranded DNA-binding protein, and the mitochondrial RNA polymerase (which most likely functions as the mtDNA primase. Mutations in the genes coding for the first three proteins are associated with human diseases and premature aging, justifying the research interest in the genetic, biochemical and structural properties of the mtDNA replication machinery. Here we summarize these properties and discuss the current models of mtDNA replication in animal cells.

Cows (n=227, 60-80 days postpartum, received estradiol benzoate (5mg and a vaginal device containing 250µg of medroxyprogesterone acetate (MPA; day 0. On day six, cloprostenol (125µg and eCG (400IU were administrated and calves were weaned for 88h. The devices were removed on day seven (BioRep group or on day eight (TAI group. All cows of TAI group and cows of BioRep group that did not exhibit standing estrus received GnRH (100µg on day 9. In experiment I, the follicular growth was monitored daily by transrectal ultrasound exams, from day 6 to day 9. The average size of the dominant follicle on day nine was 11.1±0.99mm (BioRep, n=7 and 11.5±0.65mm (TAI, n=7 and all animals ovulated. In experiment II, the BioRep group cows (n=106 were observed for estrous behavior after withdrawal of the device, twice a day for 48h, and inseminated 12h after detection. In the TAI group (n=107, the devices were withdrawn on day eight and after 24h these cows and those from the BioRep group, which were not stand in estrus, received 100µg of GnRH and TAI 16h later. The pregnancy rates were 57.6% (BioRep and 52.3% (TAI. In conclusion, an increase on MPA exposure time did not affect the follicular dynamics and pregnancy rates and allow TAI without estrous observation. Furthermore, the treatment for eight days provides an efficient TAI system in suckled beef cows.O objetivo deste estudo foi desenvolver um protocolo de inseminação artificial com tempo fixo (IATF em vacas de corte durante período de amamentação, avaliando o intervalo entre a retirada do progestágeno e a aplicação de GnRH sobre a dinâmica folicular e a prenhez.

  5. Oxygen and Early Animal Evolution

    Science.gov (United States)

    Xiao, S.

    2012-12-01

    It is often hypothesized that the rise of animals was triggered by an increase in O2 levels in the atmosphere and oceans. However, this hypothesis is remarkably difficult to test, because the timing of animal divergences is poorly resolved, the physiology of early animals is often unknown, estimates of past pO2 levels come with large error bars, and causal relationships between oxygenation and animal evolution are difficult to establish. Nonetheless, existing phylogenetic, paleontological, and geochemical data indicate that the evolution of macroscopic animals and motile macrometazoans with energetically expensive lifestyles may be temporally coupled with ocean oxygenation events in the Ediacaran Period. Thus, it is plausible that ocean oxygenation may have been a limiting factor in the early evolution of macroscopic, complex, and metabolically aggressive animals (particularly bilaterian animals). However, ocean oxygenation and animal evolution were likely engaged in two-way interactions: Ediacaran oxygenation may have initially lifted a physiological barrier for the evolution of animal size, motility, and active lifestyles, but subsequent animal diversification in the Paleozoic may have also changed oceanic redox structures. Viewed in a broader context, the early evolutionary history of animals was contingent upon a series of events, including genetic preparation (developmental genetics), environmental facilitation (oceanic oxygenation), and ecological escalation (Cambrian explosion), but the rise of animals to ecological importance also had important geobiological impacts on oceanic redox structures, sedimentary fabrics, and global geochemical cycles.

    The primary objective of this research project is to test the hypothesis that corticosteroids contribute to the adverse skeletal effects of space flight. To achieve this objective, serum corticosteroids, which are known to increase during space flight, must be maintained at normal physiologic levels in flight rats by a combination of adrenalectomy and corticosteroid supplementation via implanted hormone pellets. Bone analyses in these animals will then be compared to those of intact flight rats that, based on past experience, will undergo corticosteroid excess and bone loss during space flight. The results will reveal whether maintaining serum corticosteroids at physiologic levels in flight rats affects the skeletal abnormalities that normally develop during space flight. A positive response to this question would indicate that the bone loss and decreased bone formation associated with space flight are mediated, at least in part, by corticosteroid excess.

Few objects convey wealth and power like a private airplane, but one day you won't have to be rich or famous to fly one. NASA is working with industry and other government agencies to develop the technology and vision for business and personal travel of the future. It's a future in which travelers fly to their destinations in small, safe, affordable and easy-to-use jets out of 'smart airports.' Future small aircraft may cost about as much as a luxury automobile. They will use 25% less fuel than today's airplanes with fuel efficiencies rivaling automobiles, but at four times highway speeds. The goal is to put 'wings on America' and enable doorstep-to-destination travel at four times the speed of highways, making it possible to go where you want, when you want - faster than ever.

  10. Building for animal production

    International Nuclear Information System (INIS)

    In order to limit the radiation dose to persons working with animal husbandry in severe fallout situations, it was considered necessary to make an inventory of the Swedish livestock buildings as to number, location, use and size. These data as well as data on geometry of buildings, building material and thickness of the material in walls and roofs are given in the present work. On the basis of the mentioned data, calculations were made of the shielding factors of different types of livestock buildings. The collected data can also be used in preparedness planning in relation to housing facilities for livestock and location and size of animal production in situations of crises or war. The calculations show shielding factors for different types of livestock buildings of normal ground area within the range of 0.18-0.71. The higher value indicates a fairly poor shielding effect. The inventory and the calculations show that in those regions in Sweden where the main part of the livestock is managed, the types of buildings are, however, characterized by radiation shielding factors of 0.3-0.4. Calculation were also made of the radiation level inside the buildings following decontamination of roofs or of surrounding ground. Ground decontamination only, i.e., removal of the upper contaminated surface layer, will reduce the radiation level inside the building. For most buildings the radius of the surrounding area to be decontaminated has to be 15-30 times larger than the width of the building in order to achieve a 50 percentage reduction of the radiation level inside the building. For buildings of medium or large size and with thick walls the radiation contribution from the roof is greater than the radiation from the ground, and regardless of the size of the ground areas decontaminated the radiation level inside these buildings will only be reduced by 20-30%. 15 refs, 11 figs, 14 tabs

    This animation shows how the Large Hadron Collider (LHC) works. The film begins with an aerial view of CERN near Geneva, with outlines of the accelerator complex, including the underground Large Hadron Collider (LHC), 27-km in circumference. The positions of the four largest LHC experiments, ALICE, ATLAS, CMS and LHCb are revealed before we see protons travelling around the LHC ring. The proton source is a simple bottle of hydrogen gas. An electric field is used to strip hydrogen atoms of their electrons to yield protons. Linac 2, the first accelerator in the chain, accelerates the protons to the energy of 50 MeV. The beam is then injected into the Proton Synchrotron Booster (PSB), which accelerates the protons to 1.4 GeV, followed by the Proton Synchrotron (PS), which pushes the beam to 25 GeV. Protons are then sent to the Super Proton Synchrotron (SPS) where they are accelerated to 450 GeV. The protons are finally transferred to the two beam pipes of the LHC. The beam in one pipe circulates clockwise while ...

    2004-01-01

    This animation shows the location of the newly discovered planet-like object, dubbed 'Sedna,' in relation to the rest of the solar system. Starting at the inner solar system, which includes the orbits of Mercury, Venus, Earth, and Mars (all in yellow), the view pulls away through the asteroid belt and the orbits of the outer planets beyond (green). Pluto and the distant Kuiper Belt objects are seen next until finally Sedna comes into view. As the field widens the full orbit of Sedna can be seen along with its current location. Sedna is nearing its closest approach to the Sun; its 10,000 year orbit typically takes it to far greater distances. Moving past Sedna, what was previously thought to be the inner edge of the Oort cloud appears. The Oort cloud is a spherical distribution of cold, icy bodies lying at the limits of the Sun's gravitational pull. Sedna's presence suggests that this Oort cloud is much closer than scientists believed.

    Sea-biological basic knowledge for divers is offered only in special lessons for advanced scuba divers. According to statistics, however, five per cent of the deadly diving accidents are caused by underwater organisms. This number could be reduced to a fraction, by correct behaviour during the dive and after an accident. The most frequent accidents with sea animals during water sports are not by unprovoked shark attacks, which cause six deaths world-wide per year on the average, but turn out with usually well camouflaged sea inhabitants, that do not attack humans, rather by their inadvertence coincidentally get in contact with it. The various defense instruments of the often small, inconspicuous organisms reach from teeth over poison stings, pricks, spines, scalpelles, nettle injections and chemical weapons up to poison arrows. Due to that variety of the maritime life, the most important representatives of its type are explained including severity level of the caused injury or contamination.

    2008-01-01

    This animation consists of two close-up images of 'Snow Queen,' taken several days apart, by the Robotic Arm Camera (RAC) aboard NASA's Phoenix Mars Lander. Snow Queen is the informal name for a patch of bright-toned material underneath the lander. Thruster exhaust blew away surface soil covering Snow Queen when Phoenix landed on May 25, 2008, exposing this hard layer comprising several smooth rounded cavities beneath the lander. The RAC images show how Snow Queen visibly changed between June 15, 2008, the 21st Martian day, or sol, of the mission and July 9, 2008, the 44th sol. Cracks as long as 10 centimeters (about four inches) appeared. One such crack is visible at the left third and the upper third of the Sol 44 image. A seven millimeter (one-third inch) pebble or clod appears just above and slightly to the right of the crack in the Sol 44 image. Cracks also appear in the lower part of the left third of the image. Other pieces noticeably shift, and some smooth texture has subtly roughened. The Phoenix team carefully positioned and focused RAC the same way in both images. Each image is about 60 centimeters, or about two feet, wide. The object protruding in from the top on the right half of the images is Phoenix's thermal and electrical conductivity probe. Snow Queen and other ice exposed by Phoenix landing and trenching operations on northern polar Mars is the first time scientists have been able to monitor Martian ice at a place where temperatures are cold enough that the ice doesn't immediately sublimate, or vaporize, away. The Phoenix Mission is led by the University of Arizona, Tucson, on behalf of NASA. Project management of the mission is by NASA's Jet Propulsion Laboratory, Pasadena, Calif. Spacecraft development is by Lockheed Martin Space Systems, Denver.

    Hemsworth, P H; Mellor, D J; Cronin, G M; Tilbrook, A J

    2015-01-01

    Animal welfare is a state within the animal and a scientific perspective provides methodologies for evidence-based assessment of an animal's welfare. A simplistic definition of animal welfare might be how the animal feels now. Affective experiences including emotions, are subjective states so cannot be measured directly in animals, but there are informative indirect physiological and behavioural indices that can be cautiously used to interpret such experiences. This review enunciates several key science-based frameworks for understanding animal welfare. The biological functioning and affective state frameworks were initially seen as competing, but a recent more unified approach is that biological functioning is taken to include affective experiences and affective experiences are recognised as products of biological functioning, and knowledge of the dynamic interactions between the two is considered to be fundamental to managing and improving animal welfare. The value of these two frameworks in understanding the welfare of group-housed sows is reviewed. The majority of studies of the welfare of group-housed sows have employed the biological functioning framework to infer compromised sow welfare, on the basis that suboptimal biological functioning accompanies negative affective states such as sow hunger, pain, fear, helplessness, frustration and anger. Group housing facilitates social living, but group housing of gestating sows raises different welfare considerations to stall housing, such as high levels of aggression, injuries and stress, at least for several days after mixing, as well as subordinate sows being underfed due to competition at feeding. This paper highlights the challenges and potential opportunities for the continued improvement in sow management through well-focused research and multidisciplinary assessment of animal welfare. In future the management of sentient animals will require the promotion of positive affective experiences in animals and this

  9. An animal welfare perspective on animal testing of GMO crops.

    Kolar, Roman; Rusche, Brigitte

    2008-01-01

    The public discussion on the introduction of agro-genetic engineering focuses mainly on economical, ecological and human health aspects. The fact is neglected that laboratory animals must suffer before either humans or the environment are affected. However, numerous animal experiments are conducted for toxicity testing and authorisation of genetically modified plants in the European Union. These are ethically questionable, because death and suffering of the animals for purely commercial purposes are accepted. Therefore, recent political initiatives to further increase animal testing for GMO crops must be regarded highly critically. Based on concrete examples this article demonstrates that animal experiments, on principle, cannot provide the expected protection of users and consumers despite all efforts to standardise, optimise or extend them.

    International Nuclear Information System (INIS)

    Information on the behaviour of strontium, caesium, ruthenium, plutonium and americium in a range of domestic animals is reviewed to form a basis for the specification of time-dependent mathematical models describing uptake, distribution and retention in various domestic animals. Transfer factors relating concentration in animal product to daily radioactivity intake are derived after 100 d continuous intake and at equilibrium. These transfer factors are compared with the available published literature and used as a basis for the derivation of feedingstuff conversion factors relating limiting concentrations in animal feedingstuffs to limiting concentrations in human foodstuffs for application to animals receiving commercial feedingstuffs after a nuclear accident. Recommended transfer factors for animal products in conditions of continuous discharge and models for application to field conditions after a nuclear accident are also presented. Transfer of caesium to animal products is more effective than that for the other elements considered here. Transfer to meat of lamb, fattening pig, and chickens is generally more effective than that for other animals and other products

    Colorectal cancer is a heterogeneous disease that afflicts a large number of people in the United States. The use of animal models has the potential to increase our understanding of carcinogenesis, tumor biology, and the impact of specific molecular events on colon biology. In addition, animal models with features of specific human colorectal cancers can be used to test strategies for cancer prevention and treatment. In this review we provide an overview of the mechanisms driving human cancer, we discuss the approaches one can take to model colon cancer in animals, and we describe a number of specific animal models that have been developed for the study of colon cancer. We believe that there are many valuable animal models to study various aspects of human colorectal cancer. However, opportunities for improving upon these models exist. PMID:23076650

  18. SKIN DETECTION OF ANIMATION CHARACTERS

    Directory of Open Access Journals (Sweden)

    Kazi Tanvir Ahmed Siddiqui

    2015-02-01

    Full Text Available The increasing popularity of animes makes it vulnerable to unwanted usages like copyright violations and pornography. That’s why, we need to develop a method to detect and recognize animation characters. Skin detection is one of the most important steps in this way. Though there are some methods to detect human skin color, but those methods do not work properly for anime characters. Anime skin varies greatly from human skin in color, texture, tone and in different kinds of lighting. They also vary greatly among themselves. Moreover, many other things (for example leather, shirt, hair etc., which are not skin, can have color similar to skin. In this paper, we have proposed three methods that can identify an anime character’s skin more successfully as compared with Kovac, Swift, Saleh and Osman methods, which are primarily designed for human skin detection. Our methods are based on RGB values and their comparative relations.

    Migration is a widespread phenomenon among many taxa. This complex behaviour enables animals to exploit many temporally productive and spatially discrete habitats to accrue various fitness benefits (e.g. growth, reproduction, predator avoidance). Human activities and global environmental change represent potential threats to migrating animals (from individuals to species), and research is underway to understand mechanisms that control migration and how migration responds to modern challenges. Focusing on behavioural and physiological aspects of migration can help to provide better understanding, management and conservation of migratory populations. Here, we highlight different physiological, behavioural and biomechanical aspects of animal migration that will help us to understand how migratory animals interact with current and future anthropogenic threats. We are in the early stages of a changing planet, and our understanding of how physiology is linked to the persistence of migratory animals is still developing; therefore, we regard the following questions as being central to the conservation physiology of animal migrations. Will climate change influence the energetic costs of migration? Will shifting temperatures change the annual clocks of migrating animals? Will anthropogenic influences have an effect on orientation during migration? Will increased anthropogenic alteration of migration stopover sites/migration corridors affect the stress physiology of migrating animals? Can physiological knowledge be used to identify strategies for facilitating the movement of animals? Our synthesis reveals that given the inherent challenges of migration, additional stressors derived from altered environments (e.g. climate change, physical habitat alteration, light pollution) or interaction with human infrastructure (e.g. wind or hydrokinetic turbines, dams) or activities (e.g. fisheries) could lead to long-term changes to migratory phenotypes. However, uncertainty remains

  2. Enclosure for small animals during awake animal imaging

    Science.gov (United States)

    Goddard, Jr., James S

    2013-11-26

    An enclosure or burrow restrains an awake animal during an imaging procedure. A tubular body, made from a radiolucent material that does not attenuate x-rays or gamma rays, accepts an awake animal. A proximal end of the body includes an attachment surface that corresponds to an attachment surface of an optically transparent and optically uniform window. An anti-reflective coating may be applied to an inner surface, an outer surface, or both surfaces of the window. Since the window is a separate element of the enclosure and it is not integrally formed as part of the body, it can be made with optically uniform thickness properties for improved motion tracking of markers on the animal with a camera during the imaging procedure. The motion tracking information is then used to compensate for animal movement in the image.

  3. Animal models for human diseases.

    Rust, J H

    1982-01-01

    The use of animal models for the study of human disease is, for the most part, a recent development. This discussion of the use of animal models for human diseases directs attention to the sterile period, early advances, some personal experiences, the human as the model, biological oddities among common laboratory animals, malignancies in laboratory animals, problems created by federal regulations, cancer tests with animals, and what the future holds in terms of the use of animal models as an aid to understanding human disease. In terms of early use of animal models, there was a school of rabbis, some of whom were also physicians, in Babylon who studied and wrote extensively on ritual slaughter and the suitability of birds and beasts for food. Considerable detailed information on animal pathology, physiology, anatomy, and medicine in general can be found in the Soncino Babylonian Talmudic Translations. The 1906 edition of the "Jewish Encyclopedia," has been a rich resource. Although it has not been possible to establish what diseases of animals were studied and their relationship to the diseases of humans, there are fascinating clues to pursue, despite the fact that these were sterile years for research in medicine. The quotation from the Talmud is of interest: "The medical knowledge of the Talmudist was based upon tradition, the dissection of human bodies, observation of disease and experiments upon animals." A bright light in the lackluster years of medical research was provided by Galen, considered the originator of research in physiology and anatomy. His dissection of animals and work on apes and other lower animals were models for human anatomy and physiology and the bases for many treatises. Yet, Galen never seemed to suggest that animals could serve as models for human diseases. Most early physicians who can be considered to have been students of disease developed their medical knowledge by observing the sick under their care. 1 early medical investigator

    Markerless highly-detailed performance capture is an emerging technology in vision-based graphics and 3D video. For instance, a framework for generating mesh animations from multi-view silhouettes is presented in [Vlasic et al. 2008]. Achieving inverse animation by approximating dynamic mesh using rigid skinning has inspired researchers to convert video-based reconstructed mesh sequence into rigid kinematic parameters as seen in [de Aguiar et al. 2008].

    2013-12-01

    Oxford Sparks is a portal that launched in 2012, with the aim of bringing together resources that have been created across the University of Oxford and elsewhere for the purpose of wider engagement with science. To bring attention to this site, Oxford Sparks developed a set of high-quality short animations, each designed to tell a story relating to a current area of science. These animations have been launched on YouTube, and will shortly be available on iTunesU, and have covered broad areas of science from subduction zones (';Underwater Volcano Disaster'), through the early history of the solar system (';Rogue Planet') to the workings of the Large Hadron Collider (';A quick look around the LHC'). The animations have each been developed in close collaboration with researchers, created by a team with experience of education, engagement and outreach. The two minute scripts are intended to be both widely accessible and viewable as ';stand alone' stories. To this end, the scripts are humorous; while the animations are delightfully quirky, and created by professional animator with a degree-level science background. The animations are also intended to be used as ';lesson starters' in school, and educational activities graded for different age groups are being developed in parallel with the animations. They have been used, successfully, on pre-university summer schools, and in university classes. We are gathering both quantitative (analytics) and qualitative (school teacher and student focus group) feedback to monitor the success of the project, and to understand the strengths and weaknesses of the approach. In the first year since launch, Oxford Sparks animations were viewed over 80,000 times on YouTube, in part due to the surge of interest in the Large Hadron Collider animation after the discovery of the Higgs Boson.

    2013-09-03

    An animal litter composition that includes geopolymerized ash particulates having a network of repeating aluminum-silicon units is described herein. Generally, the animal litter is made from a quantity of a pozzolanic ash mixed with an alkaline activator to initiate a geopolymerization reaction that forms geopolymerized ash. This geopolymerization reaction may occur within a pelletizer. After the geopolymerized ash is formed, it may be dried and sieved to a desired size. These geopolymerized ash particulates may be used to make a non-clumping or clumping animal litter or other absorbing material. Aluminum sulfate, clinoptilolite, silica gel, sodium alginate and mineral oil may be added as additional ingredients.

    Rat and squirrel monkeys experiments have been planned in concert with human experiments to help answer fundamental questions concerning the effect of weightlessness on mammalism function. For the most part, these experiments focus on identified changes noted in humans during space flight. Utilizing space laboratory facilities, manipulative experiments can be completed while animals are still in orbit. Other experiments are designed to study changes in gravity receptor structure and function and the effect of weightlessness on early vertibrate development. Following these preliminary animal experiments on Spacelab Shuttle flights, longer term programs of animal investigation will be conducted on Space Station.

    Kind, Alexander; Schnieke, Angelika

    2008-12-01

    Since its inception 20 years ago, the animal pharming industry has promoted transgenic animals as a cost-effective method of biopharmaceutical production. However, it took until 2006 for the first therapeutic product to gain regulatory approval. This was an important milestone, but scepticism still abounds. Can pharming regain investor confidence, and will society accept transgenic livestock as a production method? There is some cause for optimism, biopharmaceuticals are a large, expanding market and animal pharming has already made considerable strides. A novel production platform has been established, groundbreaking technologies developed, a necessary regulatory framework put in place. Nevertheless, despite cost advantages, pharming has become a niche production method and its long term success may depend on products unique to transgenic animals. PMID:18663595

  15. Animal studies of addictive behavior.

    Vanderschuren, Louk J M J; Ahmed, Serge H

    2013-04-01

    It is increasingly recognized that studying drug taking in laboratory animals does not equate to studying genuine addiction, characterized by loss of control over drug use. This has inspired recent work aimed at capturing genuine addiction-like behavior in animals. In this work, we summarize empirical evidence for the occurrence of several DSM-IV-like symptoms of addiction in animals after extended drug use. These symptoms include escalation of drug use, neurocognitive deficits, resistance to extinction, increased motivation for drugs, preference for drugs over nondrug rewards, and resistance to punishment. The fact that addiction-like behavior can occur and be studied in animals gives us the exciting opportunity to investigate the neural and genetic background of drug addiction, which we hope will ultimately lead to the development of more effective treatments for this devastating disorder.

    Khodanovich, M. Yu.; Kisel, A. A.

    2015-11-01

    Cerebral ischemia remains one of the most frequent causes of death and disability worldwide. Animal models are necessary to understand complex molecular mechanisms of brain damage as well as for the development of new therapies for stroke. This review considers a certain range of animal models of cerebral ischemia, including several types of focal and global ischemia. Since animal models vary in specificity for the human disease which they reproduce, the complexity of surgery, infarct size, reliability of reproduction for statistical analysis, and adequate models need to be chosen according to the aim of a study. The reproduction of a particular animal model needs to be evaluated using appropriate tools, including the behavioral assessment of injury and non-invasive and post-mortem control of brain damage. These problems also have been summarized in the review.

    Peritoneal dialysis (PD) has been extensively used over the past years as a method of kidney replacement therapy for patients with end stage renal disease (ESRD). In an attempt to better understand the properties of the peritoneal membrane and the mechanisms involved in major complications associated with PD, such as inflammation, peritonitis and peritoneal injury, both in vivo and ex vivo animal models have been used. The aim of the present review is to briefly describe the animal models that have been used, and comment on the main problems encountered while working with these models. Moreover, the differences characterizing these animal models, as well as, the differences with humans are highlighted. Finally, it is suggested that the use of standardized protocols is a necessity in order to take full advantage of animal models, extrapolate their results in humans, overcome the problems related to PD and help promote its use.

    2015-11-01

    Our current understanding of the development of refractive errors, in particular myopia, would be substantially limited had Wiesel and Raviola not discovered by accident that monkeys develop axial myopia as a result of deprivation of form vision. Similarly, if Josh Wallman and colleagues had not found that simple plastic goggles attached to the chicken eye generate large amounts of myopia, the chicken model would perhaps not have become such an important animal model. Contrary to previous assumptions about the mechanisms of myopia, these animal models suggested that eye growth is visually controlled locally by the retina, that an afferent connection to the brain is not essential and that emmetropisation uses more sophisticated cues than just the magnitude of retinal blur. While animal models have shown that the retina can determine the sign of defocus, the underlying mechanism is still not entirely clear. Animal models have also provided knowledge about the biochemical nature of the signal cascade converting the output of retinal image processing to changes in choroidal thickness and scleral growth; however, a critical question was, and still is, can the results from animal models be applied to myopia in children? While the basic findings from chickens appear applicable to monkeys, some fundamental questions remain. If eye growth is guided by visual feedback, why is myopic development not self-limiting? Why does undercorrection not arrest myopic progression even though positive lenses induce myopic defocus, which leads to the development of hyperopia in emmetropic animals? Why do some spectacle or contact lens designs reduce myopic progression and others not? It appears that some major differences exist between animals reared with imposed defocus and children treated with various optical corrections, although without the basic knowledge obtained from animal models, we would be lost in an abundance of untestable hypotheses concerning human myopia.

    Nevalainen, Timo

    2014-01-01

    If the scientist needs to contact the animal facility after any study to inquire about husbandry details, this represents a lost opportunity, which can ultimately interfere with the study results and their interpretation. There is a clear tendency for authors to describe methodological procedures down to the smallest detail, but at the same time to provide minimal information on animals and their husbandry. Controlling all major variables as far as possible is the key issue when establishing an experimental design. The other common mechanism affecting study results is a change in the variation. Factors causing bias or variation changes are also detectable within husbandry. Our lives and the lives of animals are governed by cycles: the seasons, the reproductive cycle, the weekend-working days, the cage change/room sanitation cycle, and the diurnal rhythm. Some of these may be attributable to routine husbandry, and the rest are cycles, which may be affected by husbandry procedures. Other issues to be considered are consequences of in-house transport, restrictions caused by caging, randomization of cage location, the physical environment inside the cage, the acoustic environment audible to animals, olfactory environment, materials in the cage, cage complexity, feeding regimens, kinship, and humans. Laboratory animal husbandry issues are an integral but underappreciated part of investigators' experimental design, which if ignored can cause major interference with the results. All researchers should familiarize themselves with the current routine animal care of the facility serving them, including their capabilities for the monitoring of biological and physicochemical environment.

  18. Small animal radiotherapy research platforms

    International Nuclear Information System (INIS)

    Advances in conformal radiation therapy and advancements in pre-clinical radiotherapy research have recently stimulated the development of precise micro-irradiators for small animals such as mice and rats. These devices are often kilovolt x-ray radiation sources combined with high-resolution CT imaging equipment for image guidance, as the latter allows precise and accurate beam positioning. This is similar to modern human radiotherapy practice. These devices are considered a major step forward compared to the current standard of animal experimentation in cancer radiobiology research. The availability of this novel equipment enables a wide variety of pre-clinical experiments on the synergy of radiation with other therapies, complex radiation schemes, sub-target boost studies, hypofractionated radiotherapy, contrast-enhanced radiotherapy and studies of relative biological effectiveness, to name just a few examples. In this review we discuss the required irradiation and imaging capabilities of small animal radiation research platforms. We describe the need for improved small animal radiotherapy research and highlight pioneering efforts, some of which led recently to commercially available prototypes. From this, it will be clear that much further development is still needed, on both the irradiation side and imaging side. We discuss at length the need for improved treatment planning tools for small animal platforms, and the current lack of a standard therein. Finally, we mention some recent experimental work using the early animal radiation research platforms, and the potential they offer for advancing radiobiology research. (topical review)

    Animal productivity may be measured among others, in terms of two important physiological processes of reproduction and growth each of which involves a number of integrated disciplines. Both physiological processes are controlled by interactions of genotype and environment. Reproduction essentially involves complex physiological processes controlled by secretions of endocrine glands known as hormones. On the other hand growth is determined largely by availabilty of essential nutrients. In order to achieve good reproductive and growth rates adequate and constant nutrition for livestock include pasture, cereals, tubers and their by-products as well as industrial by-products. While reproduction is essential to provide the required number and replacement of livestock, growth guarantees availability of meat. Another aspect of livestock production is disease control. An animal needs a good health to adequately express its genetic make up and utilize available nutrition. Research in animal production is aimed at improving all aspects of productivity of livestock which include reproduction, growth, milk production, egg production, good semen etc. of livestock. In order to achieve this an understanding of the biochemical and physiological processes occurring in the animal itself, and in the feedstuff fed to the animal as well as the aetiology and control of diseases affecting the animal among other factors, is desirable. A number of methods of investigation have evolved with time. These include colorimetry, spectrophotometry, chromatography, microscopy and raidoisotopic tracer methods. While most of these methods are cumbersome and use equipment with low precision, radioisotopic tracer methods utilize equipment with relatively high precision

  1. Nuclear techniques in animal agriculture

    International Nuclear Information System (INIS)

    Nuclear technology plays an integral part in research to improve the health and productivity of animals. The use of radioisotopes and ionizing radiations in animal agriculture is briefly reviewed. The radioimmunoassay techniques give the opportunity of measuring and following precisely hormonal patterns in animals over the reproductive cycle. Simply by analysing a sample of blood, milk, or other body fluid, minute hormone concentrations can be assayed and the reproductive status of the animal assessed. The radioimmunoassay procedure uses antigens which are isotopically labelled, usually with 125I, and antibodies specifically developed for each hormone. The onset of sexual maturity, of oestrus, or the influence of environmental, nutritional or other factors on the reproductive state of an animal can be studied. An example of the use of the radioimmunoassay technique is illustrated in the coordinated research program of the IAEA which focuses on improving domestic buffalo production. Nuclear techniques, particularly the use of stable and radioactive tracers are providing important insights into the functioning of the digestive system of ruminants, its qualitative dynamics and metabolism. For assessing the products of the rumen, particularly volatile fatty acids which become an energy source, and microbial proteins which become a protein source for the animal, materials labelled with 14C, 3H, 35S, 15N and 32P are used. As an illustrative example, the results of one study of nitrogen metabolism, microbial protein and rumen bypass protein synthesis in cattle are shown

  2. Tool use by aquatic animals.

    Mann, Janet; Patterson, Eric M

    2013-11-19

    Tool-use research has focused primarily on land-based animals, with less consideration given to aquatic animals and the environmental challenges and conditions they face. Here, we review aquatic tool use and examine the contributing ecological, physiological, cognitive and social factors. Tool use among aquatic animals is rare but taxonomically diverse, occurring in fish, cephalopods, mammals, crabs, urchins and possibly gastropods. While additional research is required, the scarcity of tool use can likely be attributable to the characteristics of aquatic habitats, which are generally not conducive to tool use. Nonetheless, studying tool use by aquatic animals provides insights into the conditions that promote and inhibit tool-use behaviour across biomes. Like land-based tool users, aquatic animals tend to find tools on the substrate and use tools during foraging. However, unlike on land, tool users in water often use other animals (and their products) and water itself as a tool. Among sea otters and dolphins, the two aquatic tool users studied in greatest detail, some individuals specialize in tool use, which is vertically socially transmitted possibly because of their long dependency periods. In all, the contrasts between aquatic- and land-based tool users enlighten our understanding of the adaptive value of tool-use behaviour. PMID:24101631

  3. Fantastic animals as an experimental model to teach animal adaptation

    2007-08-01

    Full Text Available Abstract Background Science curricula and teachers should emphasize evolution in a manner commensurate with its importance as a unifying concept in science. The concept of adaptation represents a first step to understand the results of natural selection. We settled an experimental project of alternative didactic to improve knowledge of organism adaptation. Students were involved and stimulated in learning processes by creative activities. To set adaptation in a historic frame, fossil records as evidence of past life and evolution were considered. Results The experimental project is schematized in nine phases: review of previous knowledge; lesson on fossils; lesson on fantastic animals; planning an imaginary world; creation of an imaginary animal; revision of the imaginary animals; adaptations of real animals; adaptations of fossil animals; and public exposition. A rubric to evaluate the student's performances is reported. The project involved professors and students of the University of Modena and Reggio Emilia and of the "G. Marconi" Secondary School of First Degree (Modena, Italy. Conclusion The educational objectives of the project are in line with the National Indications of the Italian Ministry of Public Instruction: knowledge of the characteristics of living beings, the meanings of the term "adaptation", the meaning of fossils, the definition of ecosystem, and the particularity of the different biomes. At the end of the project, students will be able to grasp particular adaptations of real organisms and to deduce information about the environment in which the organism evolved. This project allows students to review previous knowledge and to form their personalities.

    Objective To investigate the proliferative differences of adipose-derived stem cells (ADSCs) from neonatal suckling SD rats (5-d-old) and adult ones under the same culture condition.Methods ADSCs were isolated from the subcutaneous adipose tissues of neonatal suckling SD rats and adult ones,and then,type Ⅰ collagenase digestion was employed to obtain the ADSCs; the morphology of these cells was detected.The expressions of such cell surface markers as CD45,CD29 and CD90 were observed. The number of ADSCs on the 4th d of culture under the same condition and with the same planted density was compared between the neonate and adult rats. In vitro culture of the second generation of ADSCs was performed in the 96-well plates, and CCK-8 and alamar blue kit were employed to compare and quantitate the proliferative differences; optical density was observed by microplate reader. Results The ADSCs from neonatal SD rats and adult ones expressed the stem cell biomarkers: the expression of CD45 was negative, and that of CD29 was 98.04% and 93.17%,respectively,and that of CD90 was 94.92% and 93.3%,respectively,for neonate SD rat and adult ones.The cell counting results indicated that the number of ADSCs from neonatal rats ([8.87±0.13]×105 cells) was larger than that of adult ones ([4.51±0.36]×105 cells) after being cultured under the same condition and at the same planted density. The optical density value of ADSCs in neonatal rats was significantly higher than that in adult ones on the 6th and 7th d of culturing detected by CCK-8 kit and on the 2nd-7th d of culturing by alamar blue assay. Conclusion The proliferative ability of ADSCs from neonatal rats is greater than that of adult ones.%目的 比较来源于出生5dSD乳鼠和成年SD大鼠的脂肪源性干细胞(ADSCs)在同等条件下进行培养时增殖情况的差异. 方法 分别分离乳鼠和成年大鼠皮下脂肪组织并使用Ⅰ型胶原酶消化法获取ADSCs,进行形态学观察.应用流式细

    Full Text Available In terms of foreign trade, in Romania there were some major changes over the past 20 years. In this paper we have focused on the Romanian external trade. The products which have been taken into account were live animals and animal products. Thus, we have made an analyse on the Romanian imports and exports at the global level and at the European level. Focused on the animal products, on the global level, there were registered major differences during the first seven years in the analysed period. Breaking by branches, we have pointed out huge distinctions between imports and exports, where the balance of trade was completely negative. Meanwhile, to have a good view on the international trade there were made links, based on some indexes between imports, exports, GDP and investments.

It adopts a Razian conception of rights, whereby an individual possesses a right if an interest of that individual is sufficient to impose a duty on another. To ascertain whether animals have a right not to be experimented on, three interests are examined which might found such a right: the interest in not suffering, the interest in staying alive, and the interest in being free. It is argued that whi...

    Singer's utilitarian and Regan's deontological views must be rejected because: (1) they rely on criteria for moral standing that can only be known a priori and (2) if these criteria were successful, they'd be too restrictive. I hold that while mental properties may be sufficient for moral standing, they are not necessary. (3) Their criteria of moral standing do not unambiguously abrogate needless harm to animals. I defend a theory of biocentric individualism that upholds the principle of species egalitarianism while at the same time recognizing that in certain cases, human needs must outweigh the needs of non-humans. On this view, moral consideration is not conferred only on beings that have human-life mental properties. Finally, it offers an unambiguous recommendation for the abolition of harmful animal experimentation, factory farming, and killing animals for sport. PMID:16276672

    1978-01-01

    An animal exposure test system (AETS) was designed and fabricated for the purpose of collecting physiological and environmental (temperature) data from animal subjects exposed to combustion gases in large scale fire tests. The AETS consisted of an open wire mesh, two-compartment cage, one containing an exercise wheel for small rodents, and the other containing one rat instrumented externally for electrocardiogram (ECG) and respiration. Cage temperature is measured by a thermistor located in the upper portion of the rat compartment. Animal activity is monitored by the ECG and the records indicate an increase in EMG (electromyograph) noise super-imposed by the increased activity of the torso musculature. Examples of the recordings are presented and discussed as to their significance regarding toxicity of fire gases and specific events occurring during the test. The AETS was shown to be a useful tool in screening materials for the relative toxicity of their outgassing products during pyrolysis and combustion.

  20. Data base on animal mortality

    International Nuclear Information System (INIS)

    A data base on animal mortality has been compiled. The literature on LD50 and the dose-response function for radiation-induced lethality, reflect several inconsistencies - primarily due to dose assignments and to analytical methods and/or mathematical models used. Thus, in order to make the individual experiments which were included in the data base as consistent as possible, an estimate of the uniform dose received by the bone marrow in each treatment group was made so that the interspecies differences are minimized. The LD50 was recalculated using a single estimation procedure for all studies for which sufficient experimental data are available. For small animals such as mice, the dose to the hematopoietic system is approximately equal to the treatment dose, but for large animals the marrow dose may be about half of the treatment dose

This paper argues that the labelling of many violent forms of direct action carried out in the name of animal rights or environmentalism as ‘terrorism’ is incorrect. Furthermore, the claim is also made that even those acts which are correctly termed as terrorism are not necessarily wrongful acts. The result of this analysis is to call into question the terms of public debate and the legitimacy of anti-terrorism laws targeting and punishing radical activism.

    Animal models have allowed detailed study of hemodynamic alterations typical of portal hypertension and the molecular mechanisms involved in abnormalities in splanchnic and systemic circulation associated with this syndrome. Models of prehepatic portal hypertension can be used to study alterations in the splanchnic circulation and the pathophysiology of the hyperdynamic circulation. Models of cirrhosis allow study of the alterations in intrahepatic microcirculation that lead to increased resistance to portal flow. This review summarizes the currently available literature on animal models of portal hypertension and analyzes their relative utility. The criteria for choosing a particular model,depending on the specific objectives of the study, are also discussed.

    Research on animal personality can be approached from both a phenotypic and a genetic perspective. While using a phenotypic approach one can measure present selection on personality traits and their combinations. However, this approach cannot reconstruct the historical trajectory that was taken by e

  8. Nietzsche y el olvido animal

    Directory of Open Access Journals (Sweden)

    Lemm, Vanessa

    2009-04-01

    Full Text Available This essay presents a reading of Nietzsche’s second Untimely Consideration and the second essay of his On the Genealogy of Morals that reevaluates the importance of animal forgetfulness in Nietzsche’s conception of history and politics. On my account the insight in the value of animal forgetfulness allows Nietzsche to redefine memory as an artistic force, and historiography as an art of interpretation. This article relates this insight to the relation between politics and the promise in the second essay of On the Genealogy of Morals, arguing that here the rediscovery of the value of animal forgetfulness allows Nietzsche to redefine politics as a realm in which the animality of the human being can take on a creative and productive role exemplified by the promise of the sovereign individual instead of being considered as an object of domination.Este ensayo presenta una lectura de la segunda Consideración intempestiva y del segundo ensayo de La genealogía de la moral que revaloriza la importancia del olvido animal en la concepción de la historia y de la política propuesta por Nietzsche. En mi interpretación, el reconocimiento del valor del olvido animal permite a Nietzsche redefinir la memoria como una fuerza artística y la historiografía como un arte de la interpretación. Este artículo conecta esta intuición con la relación entre política y promesa establecida por Nietzsche en el segundo ensayo de La genealogía de la moral, argumentando que el descubrimiento del valor del olvido animal permite a Nietzsche redefinir la esfera de la política como una esfera en la cual la animalidad del ser humano pude tomar un rol creativo y productivo ejemplificado por la promesa del individual soberano en vez de ser considerado como un objeto de dominación y explotación.

  11. Monitoring residue in animals and primary products of animal origin

    Directory of Open Access Journals (Sweden)

    Janković Saša

    2008-01-01

    Full Text Available The objective of control and systematic monitoring of residue is to secure, by the examination of a corresponding number of samples, the efficient monitoring of the residue level in tissues and organs of animals, as well as in primary products of animal origin. This creates possibilities for the timely taking of measures toward the securing of food hygiene of animal origin and the protection of public health. Residue can be a consequence of the inadequate use of medicines in veterinary medicine and pesticides in agriculture and veterinary medicine, as well as the polluting of the environment with toxic elements, dioxins, polychlorinated biphenyls, and others. Residue is being monitored in Serbia since 1972, and in 2004, national monitoring was brought to the level of EU countries through significant investments by the Ministry of Agriculture, Forestry and Water Management. This is also evident in the EU directives which permit exports of all kinds of meat and primary products of animal origin, covered by the Residue Monitoring Program. The program of systematic examinations of residue has been coordinated with the requirements of the European Union, both according to the type of examined substance, as well as according to the number of samples and the applied analytical techniques. In addition to the development of methods and the including of new harmful substances into the monitoring programme, it is also necessary to coordinate the national regulations that define the maximum permitted quantities of certain medicines and contaminants with the EU regulations, in order to protect the health of consumers as efficiently as possible, and for the country to take equal part in international trade.

  12. Immunogenicity and protective efficacy of recombinant major envelope protein (rH3L) of buffalopox virus in animal models.

    Buffalopox virus, a zoonotic Indian vaccinia-like virus, is responsible for contagious disease affecting mainly buffaloes, cattle and humans. H3L gene, encoding for an immunodominant major envelope protein of intracellular mature virion of orthopoxviruses, is highly conserved and found to elicit neutralizing antibodies. Therefore in the present study, the immunogenicity and protective efficacy of the recombinant H3L protein of buffalopox virus in laboratory animal models has been evaluated. A partial H3L gene encoding for the C-terminal truncated ectodomain of H3L protein (1M to I280) of BPXV-Vij/96 strain was cloned, over-expressed and purified as histidine-tagged fusion protein (50 kDa) from Escherichia coli using Ni-NTA affinity chromatography. The purified rH3L protein was further used for active immunization of guinea pig (250 μg/dose) and adult mice (10 μg and 50 μg/dose) with or without adjuvants (alum, Freund's Complete Adjuvant and CpG). Subsequently, a gradual increase in antigen specific serum IgG as well as neutralizing antibody titres measured by using indirect-ELISA and serum neutralization test respectively, was noted in both guinea pigs and mouse models. Suckling mice immunized passively with anti-H3L serum showed 80% pre-exposure prophylaxis upon challenge with virulent buffalopox virus strain. An indirect-ELISA based on rH3L protein showed no cross-reactivity with hyperimmune sera against sheeppox virus (SPPV), goatpox virus (GTPV), orf virus (ORFV), foot- and- mouth disease virus (FMDV), peste des petits ruminants virus (PPRV) and bluetongue virus (BTV) during the course of study. The study highlights the potential utility of rH3L protein as a safer prophylactic and diagnostic reagent for buffalopox. PMID:26723250

    Abstract. Historically, the role of drawing in traditional animation was unequivocal. How has this role been affected or changed by the advent of computer animation, and the increasingly widespread use of digital tools in animation? Can the contemporary animator work exclusively with these digital tools and forego the use of drawing, or are these tools an extension of traditional drawing utensils?
