摘要
试验研究了玉米-豆粕型日粮中添加α-半乳糖苷酶对断奶仔猪生产性能的影响。选择180头平均体重为18kg左右的健康断奶仔猪，按随机区组设计分成3个处理组，每处理3个重复，饲喂玉米-豆粕型日粮。其中加酶对照组在基础日粮中添加0．1％含植酸酶复合酶制剂，试验组在基础日粮中添加0．15％含250U／g的α-半乳糖苷酶复合酶，进行了为期28天的试验。结果表明，玉米-豆粕型日粮中添加α-半乳糖苷酶复合酶的试验组，在28天试期中可比对照组日增重提高13．68％-24．67％，料重比降低7．89％，每kg增重饲料成本降低0．40元，经济效益提高7．98％。各项生产性能均略优于添加植酸酶复合酶的加酶对照组。说明在玉米-豆粕型日粮中添加α-半乳糖苷酶可显著提高断奶仔猪的生产性能。
An experiment was designed to study the effect of α - galactosidase on the productive performances in piglets. A total of 180 piglets with average body weight 18 kg were divided randomly into 3 groups with3 replicates per treatment. The basal diet was maize - soybean meal which was fed to the first group as the control. The second group was fed with basal diets adding 0.1% phytase. The third group was fed with basal diets adding 0.15% 250U/g α -galactosidase. The results of 28 - days experiment showed that the addition of α - galaetosidase increased aver- age daily gain by 13.68%-24.67% and reduced the feed conversion by 7.89 % of trail groups, which made the feed cost reduce 0.40 yuan/kg and increase the economy benefit 7.98%. It is concluded that addition of-α- galaetosidase to cereal -soybean meal diets in piglets have effects on growth performance.
