this experiment was conducted to evaluate the effects of supplemental l-arginine (arg) in reduced-protein diets on cardiopulmonary performance and intestinal morphology in the broilers reared at high altitude. a total of 156 day-old male broilers were randomly assigned to 3 treatments and 4 replicates of 13 chicks and reared up to 42 days of age. treatment groups were designed as a normal-prote...

Eighteen weanling horses were assigned to two treatments: limited or ad libitum feed intake. Growth and feed utilization were evaluated over a 78-wk period. Ad libitum-fed horses gained 24% more (P less than .05) weight than limit-fed horses. Total BW was distributed into 57% fore and 43% hind weight and did not differ between groups regardless of dietary treatment or age. Net gain and ADG in w...

the effect of3levels of methionine (nrc recommended, 5 percent more than nrc recommended and 10 percent more than nrc recommended) and 2 levels of fat (0 and 5 percent) on some economical traits (performance and carcass) of broilers using a 2x3 factorial experiment with completely randomized design based on two rearing stages, starter (0-3 wk) and grower (4-6 wk) was studied. anova of the effec...

The study was conducted to evaluate carcass yield and chemical composition of thigh and breast muscles of broilers fed three different lysine requirement levels: high lysine (+10% NRC), standard (NRC) and low lysine (-10% NRC) and two ways of expressing amino acids in feedstuffs (total or digestible amino acids). The results of this study showed that diet formulation based on digestible amino a...
