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 zil...

the goal of this study was to determine the effects of ?-agonist zilpaterol hydrochloride on growth performance and carcass quality in ross broiler chicken. zilpaterol hydrochloride was daily fed at levels 0, 0.2, 0.25, 0.3 mg/kg of live body weight (lbw) from d 25 to 45 of age. eighty 308 ross female broiler chickens were employed in a 20 d feeding trial of four replicates, five birds per trea...

The objective of this study was to investigate the effects of three levels of threonine (100, 95 and 90% of NRC requirements) with or without of multi strains probiotic (Primalac) on performance, carcass characteristics and blood metabolites of Japanese quails. A total of 180 one-day-old male Japanese quails were randomly allocated to six treatments with three replicates and 10 birds per each. ...
