Effects of Microbial Fermentation Feeds on Growth Performance of Weaned Piglets

[ Objective] TO study the effects of microbial fermentation feeds on growth performance of piglets, and provide the basis for their promotion and application, [ Method ] All of 60 Duroc x Landrace x Yorkshire crossbred weaned piglets, weighing 8-10 kg, were randomly housed in six groups, 10 piglets in each group. The piglets in control groups were fed with traditional daily food which contained aureomycin at 70 mg/kg . BW and concentrate feeds without antibiotics. While the piglets in experimental groups were fed with concentrate feeds without antibiotics and microbial fermentation feeds. [ Result] The results indicated that the average daily gain of experimental groups raised by 5.56%, and the feed conversion ratio reduced by 3.53% compared to control group. Moreover, the number of probiotics in the feces of experimental groups increased and pH value decreased significantly compared with the control groups （P 〈 0.05）. [ Conclusion] Microbial fermentation feeds can be used to replace antibiotics feeds, and promote healthy growth of the piglets.
