【摘要】 选用 1 1日龄健康樱桃谷鸭 30 0羽 ,随机分为三组 ,一组为对照 ,另两组在对照组日粮基础上添加0 .0 5 %两种不同类型的酶制剂 ,以研究酶制剂在肉鸭日粮中的应用效果。结果表明 :两种酶制剂均不同程度地提高了肉鸭的体增重 ,改善了肉鸭的饲料转化率 ,其中效果最好的是K .P酶 ,显著提高了肉鸭体增重 (P <0 .0 5 ) ,比对照组多增重 6 5g。从经济效益考虑 ,酶制剂的使用提高了肉鸭的经济效益 ,对充分开发利用一些非常规饲料原料有重要意义更多还原

【Abstract】 healthy ducks at the age of 11 day were divided into three groups in random, one is a control group, the others fed the diets with two different kinds of enzyme preparations of 0.05%, in order to study the feeding efficiencies of the preparations for ducks. The results showed that the gain weight and the feed conversion rate were increased, specialy the gain of the group which fed the diets containing K.P enzyme was improved remarkably, 65 g gain in weight were more than that of the control one. From consideration of economic efficiencies, the application of enzyme preparations would have an important significance for fully using some non-conventional feed materials.更多还原
