One hundred Cobb male broiler chickens with 42 days old were used to study the effect of different digestible lysine and crude proteins ratios on chemical composition and physical composition of the breast muscle meat. A completely randomized design and two hierarquic criteries of classification was used. The birds were raised and fed a basal diet until 21 days old and, from 22 to 42 days, they were fed a diet formulated with two crude protein (CP) levels (17.0 and […]
