Abstract: The high nemaline feed solid fermentation conditions with Saccharomyces cerevisiae, Lactobacillus acidophilus and Lactobacillus plautarum as fermentation starter were studied and the feeding experenment were carried out nn fattening pigs also. The optimum fermented condition were as follows:the ratio of Saccharomyces cerevisiae Lactobacillus acadophalus and Lactobacillus plautarum 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 prepared in optimum condionts were 1.31×109,8.06×108,5.67× 10'cfu/g respectively. Compared with other commercial fermentation starters the starter fermentates faster,pH decreased quicker,and the flavor, palatability of the fermented feed were obviously improved. Feeding fattening 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.
