A study was conducted to determine the effects of enzyme complex (Allzyme SSF TM) containing protease, amylase, xylanase, beta-glucanase, pectinase, cellulase and phytase on performance, toe ash and intestinal viscosity of broiler chickens fed corn-soybean meal based diets. Three sixty day-old Cobb broiler chicks were randomly allocated to three experimental groups, each comprising six replicates of 20 chicks. The experimental diets included: 1) Corn-soy diet, 2) Corn-soy diet + enzyme @ 0.02%, 3) Reformulated diet (formulated to contain 75 kcal ME, 0.1% Ca and 0.1% available P less as compared to diet 1) + enzyme @ 0.02%. Weight gain and feed intake were recorded weekly. Intestinal viscosity and toe ash content were measured at 4th and 6th wk. Supplementation of enzyme significantly improved body weight gain (2165 vs 2086 g) and reduced feed conversion ratio (1.81 Vs 1.88). The birds fed on reformulated diet with enzyme showed weight gain (2089 vs 2086 g) and feed conversion ratio (1.89 Vs 1.88) comparable to that of control diet. Enzyme addition significantly improved toe ash content and reduced intestinal viscosity. The results suggested that addition of enzyme complex (Allzyme SSFTM) found beneficial in improving the performance, toe ash content and reducing the intestinal viscosity of broiler chickens fed corn-soybean meal based diets.
