Effect of Multi-Enzymes Supplementation on Growth Performance of Broiler

Non-starch polysaccharides (NSPs) are not fully digested by broiler's endogenous enzymes and consequently the soluble NSPs in feed results in high digesta viscosity and poor retention of nutrients. Supplementation of NSPs digesting enzymes may release the nutrients from feed and reduce the anti-nutritional effects of NSPs. The present study was conducted to determine the effects of NSPs digesting enzymes (Zympex) in broiler chicks. A total of 120 day old broiler chicks (Hubbard) were categorized into 3 treatments and each treatment was having four replicates comprised of 10 chicks in each. Dietary treatments comprised of Basal diet (2740 KCal/kg) as control-1 (T1), low energy diet (2630 KCal/kg) control-2 (T2) and low energy diet with 0.5 gm/kg enzyme as T3. Multi-enzymes supplementation showed significant (P 0.05), feed consumption was significantly lower (P<0.05) in 5 th week and results showed poor FCR (P<0.05) in 2 nd , 3 rd and 4 th week but non-significant effect in 1 st and 5 th week when compared with control-1 group, which revealed the positive effect of enzyme supplementation in low energy diet. These results revealed that enzyme supplementation releases more energy from low energy diets and results in equal performance to the optimal diet.
