Abstract

A factorial experiment was conducted to compare the effects of 2 dietary ENERGY levels (3100 and 2900 Kcal/Kg) and 3 AMINO ACID profile son Cobb BROILERs performance and litter quality during the starter and grower phases. The two dietary AMINO ACID profiles were based on AMINO ACID recommendations from the National Research Council (NRC, 1994) or based on PHASE-FEEDING (PF) approach. In a third AMINO ACID profile, chickens were fed NRC recommendations during the starter period but placed on a PF system during the grower period. Dietary ENERGY level had a significant effect on BROILER performance parameters, litter nitrogen and abdominal fat percentage (P<0.05), but no significant effect on other carcass compositions (P>0.05). Dietary AMINO ACID profile did not have a significant effect on BROILER performance and carcass characteristics (P>0.05).Crude protein intake and litter nitrogen percentage were lower in BROILERs fed diets formulated up on PF approach rather than based on NRC recommendations (P<0.05). Lower feed consumption per Kg of weight gain associated with PF approach in, dictated that some benefits may be availed.
