0.05). But, the best feed conversion ratio was seen in birds fed a diet contained 400 ppm enzyme. In 22 to 35 days of age, different dietary treatments have no significant effect on growth performance. Carcass percentage of quails fed with diets contained 20 and 22% CP was significantly higher than those fed 18% CP diet (P<0.05). Also, enzyme supplementation had beneficial effects on the carcass, breast, and thigh relative weights (P<0.05). In the 13-15 days period, CP digestibility coefficient was significantly decreased by increasing the CP level from 18 or 20 to 22%. Also, protease enzyme supplementation at 200 ppm level had significantly a positive effect on CP digestibility (P<0.05). It could be concluded that the optimal dietary CP level for growing Japanese quails for 1- 21 and 22-35 days of the growing period is 22 and 18%, respectively. Also, dietary supplementation with protease enzyme at 200 ppm level could be beneficial at 1 to 21 days of age.]]>
