Effects of additive and moisture content on fermentation quality of smooth vetch silage
摘要
Abstract
The fermentation quality of smooth vetch (Vicia villosa var. ) silage kept for 60 days were investigated using smooth vetch with high (fresh) and low (wilt for 3 hours) moisture content. Ammonium formate (3, 6 L/t) , lactic acid bacteria (1.0×105 cfu/g FW) , antimicrobial mixture including sodium benzoate, sodium propionate, sodium nitrite, and hexamethylenetetramine (3, 6 L/t) were added separately at ensiling but the CK had no additives. The results indicated that the fermentation quality of smooth vetch silage with high and low moisture contents were highly significantly (P<0. 01) affected by additives, but positive performances depended on the levels. The moisture content played a highly significantly positive role in improving the fermentation quality of smooth vetch silage except for the pH value (P<0. 01). The group with low moisture content performed better than the one with high moisture content. Highly significant (P<0. 01) interactions occurred between the two factors (additives and moisture content). Overall, in the high moisture content silage group, the treatments with added ammonium formate (6 L/t) and antimicrobial mixture (3 L/t) showed the best performance in fermentation quality of smooth vetch silage. In the high moisture content silage group, all treatments showed positive effects compared with the CK but without significant differences. To make silage with high quality, reducing the moisture content and adding suitable additives before ensiling are suggested.关键词
