摘要
本试验用乳酸杆菌对基础饲料进行固态发酵，分析含水率对发酵饲料pH、乳酸含量、干物质回收率及乳酸杆菌数量变化的影响。试验设A、B、C、D和E共5个处理，含水率分别为25％、30％、35％、40％和45％，每个处理3个重复。结果表明：D组pH降低最快，乳酸杆菌数量最高；c组乳酸含量最高；干物质回收率与水分含量呈负相关。综合考虑，发酵饲料最适含水率为35％～40％。
The trial was conducted to investigate the effect of moisture content on pH ,lactic acid content,the number of lactobacillus and dry matter recovery （DMR）in lactobacillus solid-state fermentation feed.There were five groups in the test,group A, B,C, D and E,each group included 3 replications.The moisture content of these treatments were 25%, 30%, 35%,40% and 45% ,respectively.The results showed that：the pH reduced most fast in group D with the largest number of lactobacillus;group C had the highest content of lactic acid;there was a negative correlation between DMR and moisture content;the optimum moisture content of fermentation feed was 35% - 40%.
