The objective was to evaluate effects of Lactobacillus plantarum and/or cellulase on fermentation, aerobic stability and bacterial community of mixed high-moisture amaranth (AF) and rice straw (RS) silage. The mixtures were treated with no addition (C), L. plantarum (L), cellulase (F) and their combination (LF). Additives increased the abundances of Lactobacillus and reduced the abundances of Weissella, Pediococcus, Lactococcus, decreased pH, acetic acid, ammonia nitrogen and increased lactic acid concentration as compared to C silage over the ensiling period. The LF silage had the highest lactic acid concentration among all silages over the 7 d of ensiling and also the lowest abundance of Enterobacteriaceae over 30 d of ensiling. Aerobic spoilage occurred in C and LF silages after 2 d of aerobic exposure, whereas the L and F silages remained stable > 4 d. In conclusion, silage treated with LF showed best silage quality.

目的是评估植物乳杆菌和/或纤维素酶对混合高水分a菜（AF）和稻草（RS）青贮饲料的发酵，好氧稳定性和细菌群落的影响。混合物不加添加剂（C），植物乳杆菌（L），纤维素酶（F）及其组合（LF）处理。添加剂增加了乳杆菌的丰度，降低了魏氏菌，小球菌，乳球菌的丰度与青贮青贮期间相比，pH值，乙酸，氨氮和乳酸浓度降低。LF青贮饲料在青贮的7 d内乳酸含量最高，而肠菌科在30 d的青贮含量最低。有氧暴露2 d后，C和LF青贮发生有氧腐败，而L和F青贮保持稳定> 4 d。总之，用LF处理的青贮饲料显示出最佳的青贮饲料质量。
