研究了由面包酵母、嗜酸乳杆菌和植物乳杆菌组成菌系发酵高纤维固体饲料的发酵条件，对在最佳条件下的发酵饲料进行了育肥猪饲喂试验。确定的最佳发酵条件为：3种微生物的菌量配比为1∶0．35∶0．35，固体物料起始pH值7．0，接种量3％，物料初始含水量50％，环境温度30℃，发酵周期72 h。在最佳发酵条件下，固体饲料中面包酵母菌、嗜酸乳杆菌和植物乳杆菌的活菌数量分别为5．67×107，1．31×109，8．06×108 cfu/g，比市售菌剂发酵启动迅速，pH值下降快，发酵饲料酸香味浓郁，适口性强；用15％发酵饲料代替等量全价饲料饲喂育肥猪30 d，增重无显著性差异，试验猪只精神状态好，粪便成型，毛发光亮。

The high nemaline feed solid fermentation conditions with Saccharomyces cerevisiae,Lactobacillus aci-dophilus and Lactobacillus plantarum as fermentation starter were studied and the feeding experenment were carried out on fattening pigs also .The optimum fermented condition were as follows:the ratio of Saccharomyces cerevisiae, Lactobacillus acidophilus and Lactobacillus plantarum was 1∶0.35∶0.35,the feed initial pH 7.0,the inoculation proportion 3%,initial water content 50%,environmental temperature 30 ℃ and fermentation period 72 h.Viable count of three kind of microorganisms in fermented feed prapared in optimum condionts were 1.31 ×109 ,8.06 × 10 8 ,5 .67 ×10 7 cfu/g respectively .Compared with other commercial fermentation starters ,the starter fermentates fas-ter,pH decreased quicker ,and the flavor ,palatability of the fermented feed were obviously improved .Feeding fatte-ning pigs with full nutrition feed which contain 15%the fermented feed for 30 days,the results shown that the daily gain of the pigs were not significance (P>0.05),and the experiment pigs shown better situation in psychosis ,dung molding and fur lighter .
