Two experiments were conducted to determine the effects of supplemental CP source and level of urea on intestinal amino acid (AA) supply and feedlot performance of lambs fed diets based on alkaline hydrogen peroxide-treated wheat straw (AHPWS). In Exp. 1, five cannulated (ruminal, duodenal, and ileal) crossbred wethers (61 kg) were used in a 5 x 5 Latin square design. Treatments consisted of di...

The possibility of utilization dried distillers' grains with solubles (DDGS) in animal feed was investigated. Samples maize hybrids ZP 548 and 655b, DDGS obtained from 548c were used as components the feed. total protein content ranged 12.42% to 31.18%, moisture 5.49% 9.55, ash 1.85% 4.37%. contents NDF, ADF, ADL, hemicellulose cellulose fibers from: 13.90% 48.13%; 2.9% 20.69%; 0.27% 2.44%; 10....

Two experiments were conducted to evaluate the effect of feeding corn modified wet distillers grain plus solubles (MWDGS; 48% DM) co-ensiled with chopped whole plant corn (WC) on growth performance, dietary intake, and nutrient digestibility of beef cattle. In Exp. 1, 96 Angus-crossed heifers (2 yr old; 522 ± 49.1 kg BW; 5.3 ± 0.1 BCS) were stratified and blocked according to BW and stratified ...

Cereal Chern. 81(3):345-349 Grain sorghum can be a major source of policosanols, long-chained alcohols, that have beneficial physiological activities. Sorghum dried distillers grains (DDG), a by-product of ethanol production from grain sorghum. contain a large amount of policosanols. Content and composition of policosanols in long-chained lipids extracted from grain sorghum kernels and DDG were...

Introduction The question of how altruism evolves despite selfish behaviors benefitting agents has for many years been the central theme in the fields such as biology, ecology, sociology, economy and psychology. Several mechanisms promoting the evolution of cooperation have been proposed and can be broadly classified into two categories: direct fitness benefits or indirect fitness benefits (Wes...
