Abstract A full understanding of changes of the microbiome and metabolome during Napier grass silage in relation to aerobic exposure can improve the nutritional value and extend the aerobic stability of this important feed in tropical and subtropical regions. The round bale silage of Napier grass was prepared with deionized water (control) and screened strains Lactobacillus rhamnosus LR753 (LR753) and L. buchneri 40788 (LB). Silages were stored at ambient temperature (30−40 °C) for 60 days, followed by 2 and 4 days of aerobic exposure. Strains LB and LR753 significantly improved aerobic stability (>84 h vs. 18 h of control) of baled Napier grass silage by inhibiting the growth of Saccharomycetales as for the higher production of acetic acid (P

在青贮和有氧暴露期间用筛选的乳酸菌制备的纳皮尔草青贮的微生物组和代谢组

摘要 充分了解纳皮尔草青贮期间微生物组和代谢组与有氧暴露相关的变化可以提高营养价值并延长这种重要饲料在热带和亚热带地区的有氧稳定性。用去离子水（对照）和筛选菌株鼠李糖乳杆菌 LR753 (LR753) 和布氏乳杆菌 40788 (LB) 制备圆包青贮纳皮尔草。青贮饲料在环境温度 (30-40 °C) 下储存 60 天，然后进行 2 天和 4 天的有氧暴露。LB 和 LR753 菌株通过抑制酵母菌的生长显着提高了打包 Napier 草青贮的有氧稳定性（> 84 小时与对照的 18 小时），因为乙酸产量更高（P
