    This experiment was conducted with, 360 male chicks to determine the effects of enzyme addition to broiler feeds, based on corn and soybean, on the performance of broiler. Chicks were distributed by 3 main groups named as Control, Treatment 1 and Treatment 2. Each of the main group contained 10 replication groups of 12 chicks. The starter and grower feeds of the groups were as follows: Control : Corn and soybean based basal diets (starter: 3100 kcallkg ME and 22 % CP, grower: 3200 kcallkg ME and 20 % CP) : Basal diets plus enzyme 1500) Treatment 2: The diet eontained less 2.5% metabolisable energy and crude protein than basal diet plus enzyme 1500). Weight gain of the control, treatment 1 and treatment 2 groups were 1640, 1700 and 1606 g respectively. There were no statistically important difference between weight gains of control and Treatment 2 but Treatment I had importantly higher weight gain than Treatment 2 (P < 0.05). Feed efficiency of the groups were 2.33, 2.25 and 2.27, respectively. Differences between feed efficiency values of the groups were not significant. Groups of Treatment 1 and Treatment 2 had higher carcass dressing percentage than that of the control (P < 0. 05). The data suggested that enzyme supplementation to corn - soybean based broiler diets had beneficial effects on weight gain, feed efficiency and carcass dressing persentage.
