Abstract

The effect of FOS on intestinal bacteria and performance of broilers was evaluated.96 broilers were randomly assigned to two groups,with four replicates of 12 dirds each.The control group(Ⅰ)was fed with the basal diet.FOS (Ⅱ)was added to the basal diet at the level of 1.5% to form the experimental diet.Body weight,feed intake and feed efficiency were measured weekly.The feeding trial starts form 1d to 49d.At dat 14,21,35 and 49,four broilers per group were killed and the cecum removed to measure Bifidobacteria,coliform,pH and moisture content.The results indicated that dietary FOS significantly increased Bifidobacteria concentration by 1.75 fold(P0 05) at 14d of age and 1.45 fold (P0 05) at 21d of age.FOS had no effect on pH and moisture content.FOS had no effect on weight gain,feed intake,and feed conversion(P0 05) $$$$
