Fermentation Quality, Bacterial Community, and Aerobic Stability of Perennial Recut Broussonetia papyrifera Silage with Different Additives and Wilting Time

Broussonetia papyrifera L. (paper mulberry) is an alternative woody plant, which can used to replace part of the protein feed for ruminants. Ensiling effective way preserve fresh pasture and solve problem stable storage conversion paper mulberry in rapid growth period. However, low dry matter (DM), water-soluble carbohydrate, lactic acid bacteria (LAB) reduce quality silage. This study assesses influence wilting time (0 h 3.5 h; lighting: 3.43 × 104 Lux) three additives (Enterococcus durans, CL; cellulase, CE; formic acid, FA) on fermentation quality, aerobic stability, bacterial community whole plant B. The sample was mowed wilted 0 h, then had CL, CE, or FA added, followed by 60 days ensiling. results show all silage samples high with pH below 4.2, ammonia-nitrogen 100 g/kg DM, no detectable butyric acid. protected DM crude from protease activity (p < 0.05), CL most among them. Furthermore, influenced silage’s communities, but overall, treatment greatest impact communities. Wilting significantly improved stability 0.05). Enterococcus positively correlated (LA), while negatively LA Weissella 0.001). identified as main driver ensiling process present study. In conclusion, compared other additives, LAB economical improve degradation Our findings provide a theoretical basis production
