主　　题：α-tocopherol Klebsiella Lactobacillus plantarum rice straw silage 

摘      要：Silage serves as the indispensable diet of ruminants,the increasing mechanism of α-tocopherol during silage making is *** straw lacks chlorophyll after harvesting the grain,this can eliminate the impact of tocopherols formed by the breakdown of ***,we explored the α-tocopherol source,its influencing factor,and its relationship with dominant lactic acid bacteria in rice straw silage treated without or with different additives(sodium benzoate,Lactobacillus plantarum,cell wall degrading enzymes,the combination of *** and cell wall degrading enzymes)and vacuum times(5,8,11,and 14 s)after ensiling for 42 *** found that the pathogenic Klebsiella was traced as the source of increasedα-tocopherol in rice straw *** residue air in the silo,pH value,and additive variety had impacts on Klebsiella activity,which was strongly active at levels of residue air in the silo and pH that were *** an acidic niche creator,*** was more effective than sodium benzoate in restraining *** having a low acidity tolerance,Klebsiella was still present in rice straw silage treated with *** relationship between Klebsiella and *** was that Klebsiella could affordα-tocopherol to the multiplication of *** and residue capsular polysaccharide protected Klebsiella from escaping the extinction in rice straw silage.
