摘要
在早期断奶仔猪饲粮中添加０１％的微生物来源复合酶制剂，进行两个阶段的比较饲养试验。结果表明，第一阶段（３８日龄～５６日龄）效果明显，加酶组仔猪体增重比对照组提高１０５６％，饲料效率提高１４４２％；第二阶段（５７日龄～７６日龄）两组猪体增重和饲料效率相近，全期试验加酶组猪体增重提高１８２％，饲料效率提高７０８％，增重饲料成本降低６３５％，平均每头仔猪节约饲料费用４３４元，经济效益显著。
The comparative feeding trials were carried out in two stages for the early weanling
piglets fed on the diets with the addition of 0.1% compound enzyme preparation from
microorganism. The results showed that the weight gain of the weanling piglets fed on the diets
containing enzyme was increased by 10.56%, and the feed conversion efficiency was increased
by 14.42% comparing with the control group in the first stage (3856 days). And the piglet gain
and the feed conversion effciency of two groups in the second stage (5775 days)were not
obvious. In the whole experimental period,the weight gain of the experimental group was
increased by 1.82%,the feed convesion efficiency was improved by 7.08%, and the cost of feed
was reduced by 6.35%. The average feed cost for each piglet was reduced by 4.34 Yuan,so the
economic benefits were remarkable.
