| 摘 要： | 通过添加蔗糖(2.0%)和甲酸(0.4%),调制沙打旺青贮饲料,研究了添加剂对沙打旺青贮发酵品质,营养价值和有氧稳定性的影响。结果表明:沙打旺直接青贮品质差;2.0%蔗糖处理能有效促进乳酸菌发酵,显著增加青贮饲料的乳酸含量,快速降低青贮饲料的pH值,较好地抑制了不良微生物的活动,使沙打旺保持良好的青贮发酵品质。0.4%甲酸处理对沙打旺青贮饲料的品质有一定的改善作用,显著提高了沙打旺青贮饲料的干物质和可溶性碳水化合物的含量。沙打旺青贮饲料的有氧稳定性较好,添加蔗糖和甲酸后可抑制二次发酵的发生。

| Abstract: | The effects of adding sucrose and formic acid to silage on fermentation quality,nutritional value and aerobical stability of the erect mlkvech was carried out.The results showed that quality of erect mlkvech silage was not good without adding any additives,while lactic acid bacteria fermentation promoted,lactic acid content increased,pH value reduced,undesirable microorganism activity restrained and fermentation quality of the erect milkvetch silages improved by treated with sucrose(2%);Treated with formic ... |
