ABSTRACT The objective was to quantify the flow of intestinal nutrients and nitrogen excretion and retention in sheep receiving isoproteic diets. Eight Texel x Lacaune wethers (average body weight = 25±2.5 kg) were fitted with duodenal cannula and housed in metabolic cages. Wethers were assigned to the treatments in a crossover design with two periods of 20 days each, and all feces and urine produced by the wethers were collected. The treatments consisted of two isoproteic (160 g kg−1 of […]

Eight crossbred steers fitted with ruminal and duodenal cannulas were randomly assigned to two replicated 4 x 4 Latin squares to evaluate the effects of crude protein (CP) levels on intake and total, ruminal and intestinal digestibility of nutrients. Animals were fed a control diet containing Tifton 85 bermudagrass hay or the control diet supplemented with urea (NPN diet), soybean meal (SBM diet) or corn gluten meal-60 (CGM diet). Indigestible acid detergent fiber was used as the internal marker for […]
