Broiler chicken growth performance, ileal microbial population and serum enzyme activity affected by dietary source of non-starch polysaccharides as supplemented with or without enzymes

An experiment was conducted to evaluate the effect of different dietary source of Non-starch polysaccharides with or without enzymes on growth performance, ileal microbial population, and serum enzyme activity of broiler chickens. A total number of 625 unsexed broiler chicken (Ross-308) were randomly assigned to 5 treatments with 5 replicates and 25 birds per each unit, using a CRD statistical design. Treatments were included control, wheat (W), wheat enzyme (WE), barley (B), and barley enzyme (BE). Feed intake and body weight gain were significantly increased, as well as feed conversion ratio decreased by diets supplemented with enzymes rather diets without enzymes (P
