Effect of enzyme complex (Allzyme SSF TM) on intestinal microflora of broiler chickens fed corn-soybean meal based diets

Department of Poultry Science
University of Agricultural Sciences, Bangalore - 560 024


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 illeal and caecal microflora 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%. At 28 d, digesta contents from the ileum and caecum were collected aseptically and Pour Plate Method was followed to enumerate the microbial population on specific media. In the illeal and caecal digesta, the viable counts of Coliforms, Streptococcus and total counts were reduced significantly with the addition of enzyme complex. The viable counts of Lactobacillus were increased significantly with the enzyme complex in cecal digesta but not in illeal digesta. The results suggested that addition of enzyme complex (Allzyme SSF TM) favors colonization of beneficial bacteria while maintaining population of pathogenic bacteria at relatively low levels both in illeal and caecal digesta of broiler chickens fed corn-soybean meal based diets.
