This study was conducted in order to evaluate the effect of four levels of pasta by product including 0, 10, 20 and 30 percentage of diet with or without enzyme on performance of broiler chickens using a 2*4 factorial design with 4 treatments and 3 replicates. During the experiment, chickens received feed and water of free access. Weight gain and feed consumption were measured at each period and feed conversion ratio was calculated. Feed consumption, weight gain and feed conversion ratio were not affected by various levels of pasta by product (p>0.05) but weight gain was significantly affected by using enzyme in diet (p<0.05). The results of this study indicated that using different levels of pasta by product had not significantly effect on performance of broiler chickens.
