| Abstract: | The objective was to evaluate the effect of lactic acid bacteria inoculant on fermentation quality and bacterial flora of alfalfa silage,the wilting alfalfa was divided into three treatment groups:control group without additives(CK group)and added 1×106 cfu/g lactic acid bacteria YX(LPI group),lactic acid bacteria ZZU A341(LPA group)respectively.Compared with CK group,LPI or LPA group has higher lactic acid content(P<0.05),lower pH and ammonia nitrogen contents(P<0.05),and both p H were reduced to below 5.00.Pediococcus(56.40%,98.63%)was the dominant genera in CK or LPI group,while Lactobacillus(98.88%)was the dominant genera in LPA group.In conclusion,lactic acid bacteria as inoculant could improve the fermentation quality of alfalfa silage by regulating the composition or relative abundance of bacterial flora. |
