The silage quality of forage soybean (FS) rich in protein with crop corn (CN) or sorghum (SG) rich in water soluble carbohydrate was investigated, and microbial community after ensiling was analyzed. Results showed that pH in mixed silages dropped to 3.5-3.8 lower than 100%FS silage (4.5). Microbial analysis indicated that mixed ensiling could influence the microbial community. Although Lactobacillus and Weissella were the dominant genera in all silage samples, Lactobacillus abundance in mixed silages (33-76%) was higher compared with 100%FS silage (27%). In conclusion, FS ensiled with CN or SG could be an alternative approach to improve FS silage quality.
研究了富含蛋白质的饲用大豆（FS）与富含水溶性碳水化合物的作物玉米（CN）或高粱（SG）混合青贮的青贮质量，并分析了青贮后的微生物群落。结果表明，混合青贮的 pH 值下降到 3.5-3.8，低于 100%FS 青贮（4.5）。微生物分析表明，混合青贮会影响微生物群落。虽然所有青贮样品中优势属均为乳杆菌属和魏斯氏菌属，但混合青贮中乳杆菌属的丰度（33-76%）高于 100%FS 青贮（27%）。总之，用 CN 或 SG 青贮 FS 可以作为改善 FS 青贮质量的一种替代方法。
