高活菌发酵饲料对生长肥育猪生产性能的影响

Effect of fermented feed on growth performance of finishing pigs

选用240头日龄相近、体况一致的杜×长×大三元杂交肥育猪,随机平均分为3个处理,对照组、试验1组和试验2组。对照组饲喂基础日粮加抗生素,试验1组和试验2组分别在基础日粮中添加4%和8%的高活菌发酵饲料。试验结果表明:在28d的饲养试验中,试验2组饲养效果最好,平均日增重比对照组提高12.34%,采食量增加7.90%,料肉比减少4.0%,腹泻率降低2.89%。应用高活菌发酵饲料饲喂生长肥育猪能起到促进其生长、减少腹泻以及改善仔猪肠道健康的功效。

In this paper, 240 Duroc-Lanndrae-Yorkshire crossbred growth growing-finishing pigs were randomly divided into three groups. The pigs in control groups were fed with traditional diets and antibiotics. While the pigs in experimental grops 1 and groups 2 were feed with traditional diets and 4% or 8% high living bacterium fermentation feeds respectively.The results indicated that the experimental groups 2 were best, the average daily gain raised by 12.34%, the feed intake raised by 7.90%, the feed conversion reduced by 4.0% and the diarrhea rate reduced by 2.89% compared with the control groups in the 28d. The high living bacterium fermentation feeds can promote growth, decrease the times of diarrhea and enhance intestinal health of the growth growing-finishing pigs.
