摘要 为了确证皮质酮(CORT)应激对肉仔鸡生产性能及血液生理生化指标的影响,试验选用108只7日龄肉仔鸡随机分为2组,对照组(CTRL)饲喂基础日粮,试验组(CORT)日粮在基础日粮中添加30 mg/kg皮质酮(饲喂2周),21日龄后两组鸡均采食基础日粮。测定肉仔鸡生产性能及血液中皮质酮、葡萄糖、钙、尿酸和游离脂肪酸含量。结果表明:8~21日龄时,皮质酮组肉仔鸡日采食量、日增重及饲料效率均显著低于对照组(P〈0.05)。8~42日龄时,皮质酮组肉仔鸡日增重显著低于对照组(P〈0.05);采食量比对照组有降低趋势(P〉0.05)。皮质酮组肉仔鸡血液中皮质酮、葡萄糖、钙及尿酸含量均显著高于对照组(P〈0.05)。结果表明,日粮长期添加皮质酮使肉仔鸡产生应激,并改变了肉仔鸡机体物质代谢。
