饲料中添加格林酶对羔羊增重效果的影响

Effect of Galenical Enzyme Added to Ration on Liveweight Gain of Lamb

选择高原型藏羊羔羊80只,随机分为3个试验组和1个对照组,每组20只,在3个试验组中分别添加格林酶0.1%、0.15%、0.2%,对照组不添加,进行试验。试验结果表明,添加0.15%水平时的增重、日增重、料重比;钙、磷、粗蛋白的表观消化率都最佳。说明饲料中添加0.15%水平的格林酶能显著提高育肥羔羊的增重和提高营养物质的利用,是最佳的日粮添加剂量。

80 Tibetan lambs of highland type were randomly divided into four groups （three test groups and one control group） and there were 20 lamps in each group.The rations of lambs in the test groups were added 0.1%,0.15%,0.2% Galenieal enzyme,respectively,and the ration of iambs in the eontral group wasn＇t added the Galanieal enzyme. The results showed that when 0.15% Galenieal enzyme were added to ration of lamb, the liveweight gain,daily gain,the ratio of feeding to body weight and the apparent digestibility of calcium, phosphorus and crude protein were the best. It was indicated that the supplement of 0.15% Galenical enzyme in the radon of fattening lamb may obtain the best liveweight gain and utilization ratio of nutritive substarice.
