摘　　要：目的:研究皮质酮对生长期肉鸡的生长性能和骨骼生物学特性的影响。方法:采用外源性皮质酮处理肉鸡的方法,80羽肉鸡随机分为对照组与皮质酮处理组,8日龄时,皮质酮处理组肉鸡每天注射皮质酮8 mg/kg,对照组注射等剂量的玉米油,为期1周。分别于15日龄和22日龄采样各组样品进行分析。结果:皮质酮可以显著降低肉鸡的体重和采食量;与对照组比较,皮质酮处理组的骨长度、骨强度、骨密度均显著降低,血钙和酸性磷酸酶水平显著增高,血磷水平显著下降。结论:皮质酮影响肉鸡的生产性能,骨代谢平衡和骨骼生长发育。Objective：The present study was conducted with broilers exposed to exogenous corticosterone（CORT）,with the aim of determining its effects on the performance and bone biological characteristics of growing broilers. Methods：Eighty broilers were randomly allocated to the control and CORT-treated groups. At 8days of age,CORT-treated group broilers were injected with CORT（8 mg/kg body weight） while the control group birds were treated with corn oil for 1 week. Samples from different groups chickens were collected at 15 days and 22 days of age. Results：CORT obviously decreased body weight and feed intake. Compared with the control group,bone length,radiographic density and strength of CORT-treated group were decreased significantly,the levels of plasma Ca and tr ACP were increased,and plasma P was decreased. Conclusion：It implied that CORT affected the performance,bone meatabolism balance and bone development in broilers
