SUMMARYForty-six cows in store condition (mean ± S.E. body weight of 366 ± 8 kg) were fed individually either 3 or 4 kg of coarsely rolled sorghum grain/head/day for the last 100 days of pregnancy and the subsequent 70 days after parturition. Eleven of the cows on each level of feeding had their calves weaned at 3 days of age.For the last 100 days of pregnancy, 3 kg of grain/head/day was an adequate ration for survival, but cows fed this ration lost a mean of 34 kg of body weight over this period compared to 8 kg by cows fed 4 kg of grain/head/day. Only 78% of the cows fed 3 kg grain/day survived to 70 days after parturition, whereas all cows fed 4 kg/day survived. There was a 44% incidence of retained placentae and metritis in cows fed 3 kg grain/day whereas those fed 4 kg/day had only an 18% incidence. Weaning of the calves at 3 days of age reduced the body weight loss of the cows by a mean of 40 kg over the first 70 days of lactation, but the effect was less for cows fed 3 kg grain (27 kg) than for those fed 4 kg grain (53 kg).Birth weight of the calves was not affected by the level of grain fed to the cows, but calves weaned and given 3 kg of milk/day plus a 50/50 creep of lucerne chaff and sorghum grain grew faster than calves not weaned and given only a sorghum grain creep.The omission of a source of calcium in the grain ration resulted in no apparent adverse clinical effects in the cows. The Na:K ratio of the saliva indicated that nine of the cows had been depleted of Na.

Groups of Hereford heifers of a mean (� SE.) body weight 187 � 3 kg were fed in yards a sole ration of sorghum grain + one per cent limestone for 26 weeks. Four groups were fed the equivalent of 1.36 kg of sorghum grain per head per day as either whole or cracked grain at either daily or twice weekly intervals. A fifth group was fed 1.64 kg of whole sorghum grain per head per day which provided a digestible dry matter intake comparable to that of 1.36 kg of cracked grain. When heifers were fed the same quantity of dry matter as whole and cracked grain, the rate of body weight loss of those fed whole grain was significantly greater than that of those fed cracked grain; and the rate of body weight loss of those fed daily was significantly greater than that of those fed twice weekly. With similar intakes of digestible dry matter from whole and cracked grain, there was no significant difference in the rate of body weight loss. Heifers from sub-groups of high initial body weight lost significantly more body weight than heifers from sub-groups of low initial body weight. The whole bodies of three heifers that died from undernutrition contained less than 0.3 per cent ether extract on a fresh weight basis, indicating complete exhaustion of body energy reserves.

A recent report suggested that brain-derived serotonin (5-HT) is critical for maintaining weight loss induced by glucagon-like peptide-1 (GLP-1) receptor activation in rats and that 5-HT2A receptors mediate the feeding suppression and weight loss induced by GLP-1 receptor activation. Here, we show that changes in daily food intake and body weight induced by intraperitoneal administration of liraglutide, a GLP-1 receptor agonist, over 4 days did not differ between mice treated with the tryptophan hydroxylase (Tph) inhibitor p-chlorophenylalanine (PCPA) for 3 days and mice without PCPA treatment. Treatment with PCPA did not affect hypothalamic 5-HT2A receptor expression. Despite the anorexic effect of liraglutide disappearing after the first day of treatment, the body weight loss induced by liraglutide persisted for 4 days in mice treated with or without PCPA. Intraperitoneal administration of liraglutide significantly decreased the gene expression of hypothalamic 5-HT2A receptors 1 h after injection. Moreover, the acute anorexic effects of liraglutide were blunted in mice treated with the high-affinity 5-HT2A agonist (4-bromo-3,6-dimethoxybenzocyclobuten-1-yl) methylamine hydrobromide 14 h or 24 h before liraglutide injection. These findings suggest that liraglutide reduces appetite and body weight independently of 5-HT synthesis in mice, whereas GLP-1 receptor activation downregulates the gene expression of hypothalamic 5-HT2A receptors.

Young Of The Year

Purpose. Assessing the results of winter keeping of paddlefish young-of-the-year in ponds of the Forest-steppe and Polesye of Ukraine. Methodology. The study was carried out using 0.05-1.0 ha ponds intended for winter keeping of carps. The stocking density of paddlefish young-of-the-year with an average weight of 94.2-147.2 g in wintering ponds was 4.10-16.63 thousand fish/ha. The study of the physicochemical parameters of the aquatic environment was carried out according to the methods generally accepted in hydrochemistry and fish farming. The main piscicultural-biological parameters during the wintering period of fish were assessed using methods commonly used in ichthyology and fish farming according to the level of survival and body weight loss of paddlefish. Findings. The environmental conditions in the ponds during most of the wintering period of fish met the biological requirements of the studied object of cultivation. The water temperature varied within 0.9-6.50C. The dissolved oxygen content in water did not fall below 3.6-3.8 mgO2/dm3 and was mainly at the level of 3.9-7.9 3.9-7.2 mgO2/dm3. Other hydrochemical parameters were within acceptable values ​​for wintering fish in pond conditions. As a result, the survival rate of paddlefish young-of-the-year during the wintering period was 81.5-89.7%. The body weight loss of fish during the winter keeping was on average in the range of 6.41-8.17%. A conclusion was made on the need to conduct additional studies of physiological and biochemical parameters of paddlefish during the wintering period. Originality. New data were obtained on the peculiarities of wintering of paddlefish seeds in ponds of the Forest-steppe and Polesye of Ukraine. Practical value. The study results are part of the database for the development of improved technologies for sturgeon breeding in Ukraine. Key words: paddlefish, fish seeds, pond aquaculture, fish wintering, environmental conditions, piscicultural parameters.

Aims. To study of the polymorphisms of the TPN2 and GNB3 genes in obese patients and their effect on weight loss in patients on sibutramine therapy. Materials and methods. The research study included 118 patients with exogenous-constitutional obesity who received Reduxin (sibutramine + CMC) at the dose of 10 mg. Term follow-up was 3 months. A genetic study was performed to assess ТРН2 and GNB3 gene polymorphisms. The response to the therapy was evaluated after 3 months by the dynamics of body weight. Results. In the study the G703T polymorphism of the GNB3 gene showed that during 3 months of observation, carriers of the TT genotype had a greater decrease in body weight in comparison with carriers of the allele C -8 kg (-12; -5) vs. -5 kg (-8; -3), p = 0.018. In carriers of different variants of the genotype of the TPH2 gene (polymorphism C825T), there was no difference in body weight dynamics with sibutramine therapy. There was no correlation between the foresaid polymorphisms of the TPH2 and GNB3 genes with the indices of blood pressure and heart rate. Conclusions. 1. The result of sibutramin therapy may depend on genetic factors: in carriers of the TT-genotype C825T of the GNB3 gene the body weight loss was higher than among the carriers of the C allele. 2. Changes in blood pressure and heart rate did not show any statistically significant relationship with polymorphisms of the TPH2 and GNB3 genes.

Factors Associated

Sheep deaths in the 12-day period following shearing were related to a high rate of body weight loss during the 4 weeks before shearing. The body weight or body condition of sheep at shearing was unimportant. Mortality level was not influenced by the amount of herbage available after shearing although the grazing activities of the survivors increased. Mortality was associated with a massive infiltration of lipid into the zona fasciculata of the adrenal cortex.The shorn sheep spent more time standing and less time grazing during the night. These results are discussed in relation to possible management practices to reduce sheep losses.

Isocaloric Diets

With adult male rats, experiments were carried out to ascertain the different effects, if any, of isocaloric diets high in carbohydrate, fat, or protein fed in restricted amounts of 9 g per rat per day on body weight loss and composition. It was observed that the nature of the diet did not alter rate, amount, or composition of body weight loss when fed in restricted amount for a period of 12 days. Further, the nature of the diet did not alter significantly the following parameters during restriction: water intake, urine volume, resting metabolic rate, spontaneous activity, urine and feces calorie values. In an experiment with hypothalamic-obese rats, the body weight loss and composition were not significantly different among the dietary-restricted groups. An important observation in this experiment was that as body fat decreased markedly owing to restricted feeding, body water increased markedly and counterbalanced approximately 60% of the potential weight loss due to the decrease in body fat. Our reported observations do not support the hypothesis that the composition of the diet may determine the rate and amount of body weight loss as a consequence of restricted food intake. They do support the hypothesis that the calorie intake, not the nature of the source of calories, determines the rate and amount of weight loss, at least for relatively short periods of food restriction.
