Abstract :This experiment was conducted to study the effects of different enzyme supplementation to wheat-and barley-based diets on the live weight gain, feed efficiency, dressing percentage and ileal pH of broiler chickens. Two hundred fourtyfive, day-old Ross-PM3 chicks were randomly assigned to a control and four treatment groups. Starter insert ignore into journalissuearticles values(1 to 21 days old); and grower insert ignore into journalissuearticles values(22 to 42 days old); diets were given without insert ignore into journalissuearticles values(control); or with different enzyme preparations, which are Avizyme 1200 insert ignore into journalissuearticles values(1000 mg/kg);, Kemzyme Dry insert ignore into journalissuearticles values(500 mg/kg);, Roxazyme-G insert ignore into journalissuearticles values(200 mg/kg); and Wheatzyme insert ignore into journalissuearticles values(700 mg/kg);. At the end of the six week, average live weights of broilers were 1793.03, 1892.55, 1820.21, 1897.96 and 1751.09 g, and feed/gain ratios were 1.95, 1.91, 1.91, 1.85 and 1.94 for control and treated groups, respectively. At slaughter, dressing percentages were 71.78, 71.98, 72.66, 73.26 and 72.89%. There were no significant differences between groups in these respects, except that the average live weights in broilers fed Avizyme 1200 and Roxazyme-G supplemented diets were 5.55% and 5.85% respectively, higher than the control insert ignore into journalissuearticles values(p
