abstract
This study was planned to evaluate the effect of varying levels of enzyme supplementation with high levels of paddy replacing maize on the nutrient utilization and carcass traits of broilers. The study was conducted for a period of five weeks. In experiment 126, day old chicks were randomly distributed into 07 dietary treatments each with 3 replicates of 6 chicks each and T₁ acted as a control. The control diets were formulated to contain 2800 Kcal ME/kg and 22% CP and enzymes @ 30gm/100kg feed. Remaining 06 treatments, were formulated by supplementing higher levels (60%,80% and 100%) of paddy replacing maize and varying levels (@ 30gm/100kg feed and @ 50gm/100kg feed) of enzymes. Use of higher level of enzymes had caused higher retention of nutrients. The percent carcass yield was maximum in broilers assigned T₅ diet. No specific trend was found in organ weight and processing losses of broilers.
