酸美酵素对仔猪生产性能影响试验

试验选择28日龄杜长大三元杂交仔猪200头,随机分为2组,每组10个重复,每个重复10头猪,对照组饲喂基础日粮,试验组在基础日粮中每吨配合饲料添加高酸型酸美酵素10 kg,试验期为43 d。结果表明,试验组仔猪日增重比对照组提高0.057 kg/（头·d）,差异显著（P<0.05）,料重比降低20%,腹泻率降低13%,差异显著（P<0.05）。试验表明,酸美酵素具有提高仔猪生产性能的作用。

Effect of a Commercially Available Biological Product on Productive Performance of Piglets

In this study, a total of 200 Duroc × Landrace × Large White three-way crossbred piglets aged 28 days were selected and randomly divided into 2 groups. There were 10 replicates for each group and 10 piglets for each replicate. The piglets in the control group were fed with the basal diet, and the piglets in the experimental group were fed with 10 kg of high-acid-type ′Suanmeijiaosu′ （a commercially available biological product） per ton of compound diet. The feeding experiment lasted for 43 days. The results showed that the daily gain of piglets in the experimental group was 0.057 kg/（head·d） higher than that in the control group, and the difference was statistically significant （P<0.05）. Compared to the control group, the feed-gain ratio and diarrhea incidence of the experimental group was decreased by 20% and 13%, respectively, and the differences were both statistically significant （P<0.05）. It was concluded that the ′Suanmeijiaosu′ could improve the productive performance of piglets. Keywords′Suanmeijiaosu′;piglets;productive performance
