摘要:

本试验研究添加乳酸菌对苜蓿(Medicago sativa.)青贮过程中发酵品质、营养成分和黄酮含量的影响。结果表明:添加乳酸菌可快速降低青贮饲料的pH值,提高乳酸和苜蓿黄酮含量,降低酸性洗涤纤维含量,而粗蛋白、中性洗涤纤维、可溶性碳水化合物、丙酸和丁酸含量无明显变化。综合分析表明添加乳酸菌可改善苜蓿青贮发酵品质,增加黄酮的提取量。

关键词: 苜蓿, 乳酸菌, 青贮品质, 黄酮

Abstract:

The aim of this study was to investigate the lactic acid bacteria on silage fermentation quality, nutritive quality and content of flavonoids of Alfalfa. The results showed that adding lactobacillus plantarum decreased pH value, increased the content of lactic acid and flavonoids, and decreased detergent fiber. The content of crude protein, neutral detergent fiber, soluble carbohydrate, propionic acid and butyric acid didn't show significant difference. In conclusion, adding lactic acid bacteria improved silage quality and enhanced the content of flavonoids.

Key words: Alfalfa, Lactic acid bacteria, Silage quality, Flavonoids
