Effects of Bacillus coagulans and Lactobacillus plantarum on the fermentation quality, aerobic stability and microbial community of triticale silage

Abstract Background Due to its hollow stem, ensiling triticale presents a challenge as it may cause an overabundance of oxygen during the fermentation process. This study investigated effects Bacillus coagulans (BC) and Lactobacillus plantarum (LP) on characteristics, microbial community, aerobic stability ensiled triticale. Fresh was wilted at dry matter content 350 g/kg. The experiment arranged in 2 × factorial design, with both BC commercial LP added 0 or 1 10 6 cfu/g fresh weight (FW) chopped Results After 60 days ensiling, pH, water-soluble carbohydrates (WSC), neutral detergent fiber (NDF), ammonia nitrogen (NH 3 -N) inoculated groups were lower than those control group ( P < 0.05), especially + treatment 0.05). lactic acid (LA) concentration, acid/acetic (LA/AA), also higher 0.05) other treatments. bacterial diversity reduced, richness increased by application individually Compared silage, LP-treated silage had while BC-treated Pediococcus , Enterococcus Serratia negatively correlated NDF AA positively LA LA/AA but pH NH -N Conclusions combination lead improved quality inducing alterations composition communities, which is crucial for efficient utilization resources.
