为研究饲粮添加不同水平α-半乳糖苷酶对爱拔益加(AA)肉鸡屠宰性能、血清生化、激素指标的影响,试验选择1日龄体重相近的健康AA肉鸡360羽,随机分成6个处理,处理A饲喂玉米-豆粕型基础饲粮(正对照处理),处理B在基础饲粮水平上降低代谢能0.21MJ/kg(负对照处理),处理C、处理D、处理E、处理F分别在负对照处理基础上添加75 mg/kg、150 mg/kg、300mg/kg、600 mg/kg的α-半乳糖苷酶制剂.结果表明:(1)处理E较其它各处理有提高21日龄试鸡胸肌率、瘦肉率及降低腹脂率的趋势;处理D较正、负对照处理对42日龄AA肉鸡胸肌率有明显提高作用(P＜0.05),同时处理D较正对照处理对42日龄试鸡瘦肉率有明显改善作用(P＜0...

To evaluate the effects of different levels ofα-galactosidase on slaughter performance,serum biochemical and hormonal indices of AA broilers,360 healthy 1-day-old AA broilers with nearly same weight were randomly selected and allocated to 6groups,5replicates in each group and 12 broilers in each replication.The positive control group was provided with the corn-soybean basal diet,the negative control group was fed the basal diet which was reduced 0.21MJ/kg ME,and the test groups（C,D,E,F）were fed the negative control diet which added 75mg/kg,1...
