Dietary self-selection and feed restriction studies with growing and breeding turkeys
… and to investigate the impact of body weight restriction on subsequent reproductive performance. In the first experiment, dietary self-selection of energy and protein and feed restriction were studied in growing turkeys. Body weight of males and females was significantly reduced by feed …

Effects of feed restriction on milk production and metabolism in mid-lactation dairy cows
… period of negative energy balance induced by feed restriction (FR) and the effect of abomasal supplementation of different amino acids (AA) or glucose. Seven multiparous Holstein cows (93 ± 15 DIM) were randomly assigned to 7 treatments in a 7 × 4 incomplete Latin square design. In 6 …

The effect of early feed restriction on the performance, organ weights, carcass composition, and lipid and protein metabolism in broiler chickens
… conducted to investigate the effects of early feed restriction on body weights, feed conversion, organ weights, fat deposition, carcass and muscle composition, plasma lipids, lipogenesis, lipolysis, and muscle tissue DNA and RNA in broiler chickens. In Experiments 1 and 2, broiler chicks were …

The Effect of Duration of Feed Restriction, Prebreeder Protein Content, and Nesting Material on Growth and Reproductive Performance of Commercial Large White Turkey Breeder Hens
… were used to examine the effect of duration of feed restriction, prebreeder protein content, and nesting material on subsequent growth and reproductive performance. Day old poults were raised following standard commercial practices with feed and water for ad libitum consumption until 6 wk of age …

Composição tecidual e características qualitativas da carne de cabritos Canindé submetidos à restrição alimentar
… of Canindé goat meat subjected to three feed restriction levels, and compare the quality of Longissimus dorsi and Semimembranosus. The experiment was conducted at the experimental station of the São João do Cariri, where were used 21 castrated goats, with an average initial weight of 15 …

L-Carnitine Supplementation for Periparturient Dairy Cows
… and prevented liver lipid accumulation during feed restriction. Feed restriction induced higher carnitine concentrations in muscle and milk but not in liver. In experiment 2, L-carnitine was supplemented as a dietary topdress (0, 6, 50, or 100 g/d) from d -14 prior to expected calving date …

Diet-induced thermogenesis in the domestic chicken
… of water in the first experiment, and by force-feeding the diet to crop capacity in the subsequent trials. Feed restriction was accomplished by providing 75% of ad libitum intake each day. Both low-weight (LN) and high-weight (HN) chicks reduced their voluntary feed intake when glucose solutions …

Effects of a polychlorinated biphenyl in mice caged at different densities and fed at different nutritional levels
… these effects were aggravated by group-caging or feed restriction. The underlying hypothesis was that PCBs may have different physiological effects, dependent on the nutritional status of the animal and the density of the population of which it is a member. The physiological characteristics …

The influence of catecholamines on energy metabolism beef colour and tenderness in three commercial beef breeds
Feed restriction and handling of animals destined to be slaughtered have are two factors that affect meat quality negatively. Where handling of slaughter animals is inevitable, fasting is applied to meat producing animals in the ante mortem period to minimise microbial contamination of carcasses or …

Stress response and habituation as influenced by nutritional and thermal factors in dwarf and normal chickens
… ratios declined in a quadratic manner with age. Feed restriction elicited a similar stress response, as indicated by H/L ratios in dwarfs and normals with the effect of adapting to fasting having dissipated between 12 to 16 days. Resistance to Eimeria tenella infection was greater in normals than …

Effect of dietary protein on plasma uric acid, body weight, and oxidative stress in broilers
… were fed LP, MP, HP or COD diets for 4 wks. Feed restriction severely restricted body weighs gain in chicks fed synthetic diets. Changes in LOA were found linked to PUA concentrations in chicks fed MP, HP and COD diets.

Management during the dry period and its effect on hepatic and adipose tissue molecular biomarkers of metabolism and health in grazing dairy cows
… in BCS4 cows in response to increased prepartum feed allowance (1071 vs 310, over the entire transition period) indicated a greater responsiveness to prepartum nutrition than optimally-conditioned cows. Thus, overfeeding in late-pregnancy should be limited to underconditioned cows, while cows …

Electrophoretic investigation of genetic characteristics in the pine vole
… voles that. survived or died on restricted feed intake was tested using starch-gel electrophoresis of 5 polymorphic enzyme markers. Three apple orchards annually treated with endrin for the past 15 years and 3 non-treated orchards in southwestern Virginia were sampled in Fall 1980, and in 2 …

Examination of the expression of genes and proteins controlling M. longissimus thoracis et lumborum growth in steers
… cattle which aimed to investigate the effect of feed restriction and feed realimentation on animal production and physiological variables and the residual effects on meat quality attributes. The final chapter in this thesis focused on the transcriptional regulation of compensatory growth in M. …

Intestinal Inflammation Model Inducing Gut Leakage by Different Methods in Broiler Chickens Using FITC-d as a Marker
… thus improving performance. Due to increasing restrictions regarding the use of AGP, precise and high throughput enteric inflammation models and markers to search for effective alternatives are urgently needed. Oral administration of fluorescein isothiocyanate dextran (FITC-d) and its passage …

Dietary Energy Restriction During Late Gestation in Multiparous Holstein Cows
… to the control group or the ketosis induction (feed restriction) group and cows with periparturient disorders (PD) were assigned to the PD group. Prepartum metabolism and CPT I activity were consistent with plane of nutrition. Prepartum intake did not affect postpartum metabolism or milk yield. …

Genotype by feeding regimen interactions in growth selected chickens
… in lines of chickens maintained under different feeding regimens. Populations included a commercial broiler breeder parent line segregating at a sex-linked feathering locus (K, k⁺) and 4 experimental lines of which 2 had undergone 32 generations of divergent selection for 56-day body weight and 2 …

Effect of neonatal heat stress on growth, mortality and blood characteristics of juvenile broilers exposed to high ambient temperature
… effects on body weight, body weight gain or feed efficiency caused by exposure of birds to early heat stress. Feed restriction or administration of a commercially available electrolyte package to the water had no effect on the ability of the birds to withstand high ambient temperature. Water …
