Recent models suggest that herbivores optimize nutrient intake by selecting patches of low to intermediate vegetation biomass. We assessed the application of this hypothesis to plains bison (Bison bison) in an experimental grassland managed with fire by estimating daily rates of nutrient intake in relation to grass biomass and by measuring patch selection in experimental watersheds in which gra...

background & aim: medicinal plants is very potential to be used as a supplementary feed as well as feed additive in broilers.this experiment was conducted to investigate the effects of milk thistle (mt) and thyme seeds (ts) on the performance in broilers. experimental: in this study, 160 one-day-old (ross 308) male broiler chicks were divided randomly into four major groups with 4 replicate...

BACKGROUND Intermittent severe energy restriction is popular for weight management. To investigate whether intermittent moderate energy restriction may improve this approach by enhancing weight loss efficiency, we conducted a study in mice, where energy intake can be controlled. METHODS Male C57/Bl6 mice that had been rendered obese by an ad libitum diet high in fat and sugar for 22 weeks wer...

ABSTRACT This study aimed to evaluate sweet potato feed as an alternative energy supplement for ovine. A latin-square design was used assess the effects of feeding animals 0, 0.5, 1 and 1.5% their body weight in well ryegrass hay (Lolium multiflorum) twice daily, mineral salt water ad libitum. During this 8 males were housed metabolic cages with urine feces collectors. Each round experimentatio...

feed intake produced 2.91 2 1.61 more live pigs from Parity 1 to 3 than those developed with ad libitum access to feed. Gilt weight and backfat at 135 days of age affected the likelihood that gilts farrowed a Parity 1 litter. The effect depended on genetic line and development regimen. Each 10 lb increaseldecrease in weight from the mean weight of 248.7 lb was associated with an increaseldecrea...

Predicting aspects of pork quality becomes increasingly important from both a nutritional and a technological point of view. Little information is, however, available concerning the quantitative relation between nutrient intake and fatty acid (FA) deposition at the whole-animal level. In this study, eight blocks of five littermate barrows were used in a comparative slaughter trial. At 24 kg bod...

Two commercial feedlot experiments and a metabolism study were conducted to evaluate the effects of monensin concentrations and bunk management strategies on performance, feed intake, and ruminal metabolism. In the feedlot experiments, 1,793 and 1,615 steers were used in Exp. 1 and 2, respectively, in 18 pens for each experiment (six pens/treatment). Three treatments were evaluated: 1) ad libit...

Dried cashew nut testa (DCNT) was characterized with respect to proximate, mineral, and energy profile. The crude protein, crude fibre, and fat and ash contents were, in g kg(-1)DM, 190.0, 103.0, 20.1, and 20.2, respectively, with metabolizable energy of 7.12 MJ kg(-1) DM. In a feeding trial, isoproteic diets containing DCNT (O, 50, 100, and 150 g kg(-1)) were fed ad libitum to 4 groups of Spra...
