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