摘要
选择高原型西藏羊 80只 ,随机分为 4个试验组 ,每组 2 0只 ,在 4个试验组中分别添加格林酶 0 .1% ,0 .15 % ,0 .2 %和 0 .2 5 %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羊的增重和提高营养物质的利用 ,是最佳的日粮添加剂量。
Tibetan sheep of plateau type were randomly divided into four test groups (20 per group).The rations of Sheep in the test groups were added 0.1%,0.15%,0.20% and 0.25% Gelin-enzyme,resp.The test resules showed that when 0.15% Gelin-enzyme were added to the ration of sheep,the liveweight gain,the ratio of feeding to body weight,the apparent digestibility of calcium,phosphorus and crude protein were the best.It was indicated that the supplement of 0.15% Gelin-enzyme in the ration may increse the liveweight gain and the utility of nutrient in the fattening sheep and was the best additive volume.
