abstract
The study was planned to evaluate the effect of varying levels of enzyme supplementation with high levels of paddy replacing maize on the performance and economics of broiler production. 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 varying levels (@ 30gm/100kg feed and @ 50gm/100kg feed) of enzymes. Maximum and significantly (p<0.05) higher weight gain, feed intake, was recorded in broilers assigned T_5, T_7, diet while, FER and PI was found in T₅ diet. Significantly (p<0.05) higher net return over feed cost on total b.wt. gain (Rs) of broilers was recorded in T₅ diet.
