This experiment was conducted to evaluate the effects of dietary levels of crude protein, methionine and betaine on performance and carcass characteristics of broiler chickens. A total of 640 one-day-old broiler chicks from Ross 308 strain were used. Each pen (1.5 ×1.5m) was assumed as experimental unit and was included 20 male and female chicks. The experiment was conducted based on completely...

In a completely randomized design with a factorial arrangement (3× 5× 3), three fistulated sheep with an average body weight of 47.5 ± 2.5 kg were used to determine the effect of cutting and growing stages (no bloom , early bloom and full bloom) on chemical composition and In situ degradability of alfalfa (Medicago sativa). Nylon bags (50 µm pore size) were filled with 3.5 g of each sample and ...
