Clostridia are undesirable microorganisms in silage, particularly in low dry matter forage, where their growth can impair silage quality and animal performance. This study screened more than 200 lactic acid bacteria for their ability to inhibit clostridia. Two newly isolated strains, Lactiplantibacillus plantarum DSM 34271 and Lactococcus lactis DSM 34262, showed clear inhibitory effects against Clostridium tyrobutyricum in agar diffusion assays. Based on these results, both strains were evaluated as silage inoculants in three slightly wilted grass materials. Compared with untreated controls, inoculated silages exhibited significantly lower pH values, increased lactic acid concentrations, reduced butyric acid formation and lower weight losses after 90 days of storage. These findings indicate improved fermentation quality and suggest effective suppression of clostridial activity by the selected strains.
