【摘要】 试验探讨了不同水平的复合酶制剂对早龄断奶仔猪生产性能的影响。结果表明 :复合酶制剂提高了仔猪的生产性能 ,试验 1～ 2周 ,添加 0 .1 % ,0 .5 % ,1 .0 %的复合酶较对照组日增重分别提高 8.1 5 % ,1 3.37% ,1 5 .5 0 % ,饲料利用率分别提高 8% ,1 6 %和 1 7.2 % ;试验 3- 4周 ,加酶的三个试验组明显好于对照组 ,以添加 0 .5 %和1 .0 %的酶其日增重和饲料增重比较对照组提高的幅度最大。从整个试验期来看 ,添加 0 .5 %的复合酶制剂其经济效益最好。更多还原

【Abstract】 It was studied by a test to determine the effects of multi-enzyme on growth performance in early weaning pigs. The result showed that the multi-enzyme improved growth performance of weaning pigs. In 1～2 weeks, ADG was increased by 8.15%, 13.37%, 15.50% and FCE was increased by 8%, 16%, 17.2% respectively as compared with control when pigs were fed with the diets containing 1.0%, 0.5%, 0.1% multi-enzyme respectively. In 3～4 weeks, with the addition of 0.5% or 0.1% multi-enzyme, ADG and FCE were increased more than other groups as compared with control. From the total trial, an addition of 0.5% multi-enzyme could produce the highest economic benefit.更多还原
