L-苹果酸对断奶仔猪生长性能的影响研究

Effect of L-malic Acid on the Growth Performance of Weaning Piglets

为评价L-苹果酸对断奶仔猪生长性能的影响,本试验选取均重6 kg左右的断奶仔猪100头(公母各半),随机均分成试验组和对照组,对照组饲喂基础日粮,试验组在每千克基础日粮中加入2.0 g L-苹果酸,两组均按常规免疫程序免疫,32d后统计仔猪存活率和增重率。结果显示:在基础日粮中添加L-苹果酸,可以提高保育阶段仔猪的存活率和增重率,增加养猪效益。

In order to study the effect of L-malic acid on the growth performance of weaning piglets,100 weaning piglets(50 male and 50 female,6 kg)were randomly divided into the experimental group and control group.The control group was fed with basic diet,and the experimental group was fed with basic diet which was added 2.0g/kg L-malic acid.The survival rate and weight gain rate of two groups′piglets were counted after feeding 32 days.The results showed that the diet added with 2.0 g/kg L-malic acid could improve the survival and weight gain rate of weaning piglets in the nursery stage and increase the raising benefit.
