为研究饲粮α-半乳糖苷酶对爱拔益加(AA)肉鸡生长性能、养分表观利用率和肠道黏膜形态结构的影响,试验选择1d体重相近的健康AA肉鸡360羽,随机分成6个处理,每处理5个重复,每重复12羽,处理A饲喂玉米-豆粕型基础饲粮作为正对照组,处理B在基础饲粮水平上降低代谢能0.21 MJ/kg,作为负对照组,处理C、D、E、F分别在负对照基础上添加75、150、300和600 g/t的α-半乳糖苷酶制剂(酶活400 U/g).结果表明:饲粮添加不同水平α-半乳糖苷酶对1～42 d各处理AA肉鸡平均日增重(ADG)、平均日采食量(ADFI)和饲料增重比(F/G)均无显著影响(P＞0.05),但150 g/t α-半乳糖苷酶组ADG最高、F/G最低;150 g/t α-半乳糖苷酶组...

To evaluate the effects of different levels of α-galactosidase on growth performance, nutrient apparent utilization and intestinal mucosa structure of AA broilers, 360 of healthy 1-day-old AA broilers with the nearly same weight were randomly a total of allocated to 6 groups, 5 replicates 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. 21 MJ / kg ME, and the test groups（ C, D, E, F） were fed the n...
