To study the working mechanisms for non-starch polysaccharides’ to improve the growth performance of broiler chickens, a 35-day feeding trial was conducted. Two dietary treatments were included: 1) wheat diet (the control); 2) wheat+xylanase diet .There were 5 groups with 3 replicates ,each replicates having 8 birds each for each treatment and the experimental diets were given to birds from hatch. Group A was control and group B was treated with Xylanase concentration of 250IU/Kg feed, Group C was treated with Xylanase concentration of 500IU/Kg feed, Group D was treated with Xylanase concentration of 750IU/Kg feed and Group E was treated with Xylanase concentration of 1000IU/Kg feed.FCR and body weight were measured weekly. The vaccination was done according to schedule. Fresh Water provided at free labitum. The shed was properly maintained with respect to temperature and humidity. The Fumagination was properly and thoroughly done before the start of experiment. The xylanase supplement increased (p<0.05) body weight gain (BWG) and improved feed conversion ratio (FCR) at the end of the experiment but non-significant results were observed on serum biochemistry (p>0.05) by xylanase.
