Abstract:

Five weeks feeding trail with 80 day old broiler chicks was conducted to find out the effect of two supplemental enzymes with ration containing high level of non starch polysaccharides (NSP). Day old chicks (Cobb) of both sexes were distributed randomly into four experimental groups with two replicates of ten birds in each replicate. A maize-soyabean meal diet formulated to have 7% total NSP served as control (T1).  Ration T2 was formulated to have 10 % total NSP. Ration T2 was fortified with enzyme mix-A (pectinase 15000 U, hemicellulase 2250 U, cellulase 2250 U, xylanase 4000 U and beta-glucanase 250 U/kg feed) and enzyme mix-B (pectinase 15000 U, hemicellulase 4500 U and cellulase 4500 U/kg diet) to form ration T3 and T4.  Birds fed high NSP diet without enzyme (T2) had slightly lower body weight gain and feed to gain ratio (1302.9±46.61g and 2.07) compared to birds fed ration T1 (1360.50±32.85g and 1.91).  Supplementation of enzymes showed relatively better body weight gain and feed to gain ratio in T2 (1328.2±33.21g and 1.94) and T3 (1354.4±46.80g and 1.91) which is comparable to that of ration T1. Excreta moisture and AME content were not altered significantly by higher level of NSP in the ration and with or without enzyme supplementation. Supplementation of enzymes showed a tendency for better AME, ileal protein digestibility, reduction in ileal NSP recovery and length and weight of various segments of intestine when compared to un-supplemented group (T2).  The results of this study indicated that broiler ration containing 10% NSP did not reduce the growth of birds significantly. However, 10% NSP containing ration can be supplemented with enzymes mixture at the rate of pectinase 15000 U, hemicellulase 4500 U and cellulase 4500 U/kg diet to compensate the feed to gain ratio in birds to that of maize soya diet.
