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 the effects of Bacillus coagulans (BC) and Lactobacillus plantarum (LP) on the fermentation characteristics, microbial community, and aerobic stability of ensiled triticale. Fresh triticale was wilted at a dry matter content of 350 g/kg. The experiment was arranged in a 2 × 2 factorial design, with both BC and commercial LP added at 0 or 1 × 106 cfu/g of fresh weight (FW) of chopped triticale. Results After 60 days of ensiling, the pH, water-soluble carbohydrates (WSC), neutral detergent fiber (NDF), and ammonia nitrogen (NH3-N) of inoculated groups were lower than those of the control group (P
