The purpose of this study was to evaluate the effect of Zilpaterol hydrochloride on the growth performance, carcass quality and blood parameters with128 male quails at 26 days of age were divided into four treatments which each treatment consists of four replicates of 8 birds. The birds received daily 0, 0.2, 0.225, or 0.25 mg/kg of live weight d−1zilpaterol. After three days of withdrawing zilpaterol, two birds were slaughtered for carcass evaluation. Results showed that zilpaterol hydrochloride supplementation improved feed conversion ratio (FCR) (P<0.5), but no effect on feed intake and weight gain. Also, zilpaterol hydrochloride increased the glucose and triglyceride concentration of plasma in comparison to treatment control (P<0.5). However, zilpaterol had no effect on carcass chemical composition (crude protein, fat, cholesterol). Furthermore, carcass weight and percentage of leg, breast, liver and abdominal fat was not affected in the treatment which were feeding zilpaterolhydrochloride. It can be concluded that Zilpaterol hydrochloride improved the FCR in Japanese Quails
