摘要: 为探讨微生物添加剂对苜蓿青贮效果的影响,以发酵活干菌和乳酸菌两种微生物复合添加剂为材料,分别设置三种不同添加浓度和对照,添加到袋装苜蓿青贮中,分别在青贮第4,8,16,30,60天后取样分析。结果表明:两种微生物复合添加剂均可以改善苜蓿青贮的发酵品质,青贮pH显著下降,抑制氨态氮含量的增加,但对干物质含量和可溶性碳水化合物含量的变化影响不显著。通过综合分析,本试验认为在苜蓿青贮中添加发酵活干菌复合添加剂2g/t或乳酸菌复合添加剂1g/t效果较好。

关键词: 微生物复合添加剂, 苜蓿, 青贮, 发酵品质

Abstract: The studies were conduced to investigate the effect of microbe compound additives on alfalfa silage at different storage periods. Living dry bacteria for fermentation additive and lactic bacteria additive were added to bagged alfalfa silage with three different concentrations each and a control. Alfalfa silage was sampled and analyzed at 4,8,16,30 and 60 d. The results showed that the fermentation quality of alfalfa silage could be enhanced by adding microbe compound additives. The additives obviously decreased the alfalfa silage pH(P < 0. 05), and reduced the ammonia nitrogen content(P < 0. 05). But dry matter content and water soluble carbohydrate content were not affected by additives. It is concluded that the alfalfa silage added living dry bacteria for fermentation additive with 2 g /t or lactic bacteria additive with 1 g /t could get better silage quality.
