摘要
在刚收获及收获后经过8h和30h晾晒的初花期草木樨Melilotusalba(干质量含量分别为27 36%,38 69%和44 98%)青贮料中,加入蔗糖(添加量分别为1 0%,1 5%和2 0%)进行青贮。结果表明,草木樨低水分(干质量含量为44 98%)青贮可以使青贮料的氨态氮含量显著降低,并保存更多的干质量、粗蛋白和可溶性糖。草木樨添加蔗糖青贮使青贮料的氨态氮含量显著升高,粗蛋白含量下降,发酵品质严重下降,因此草木樨青贮不宜用蔗糖作为青贮添加剂。
Sweetclover was harvested at the early blooming stage and wilted for 0, 8, or 30 hours (DM 27.36%, 38.69% or 44.98%, respectively), and was ensiled with sugar at a rate of 1.0%, 1.5% or 2.0%. Haylage (DM 44.98%) without additives had lower ammonia nitrogen content and higher WSC and CP contents. Sugar addition resulted in higher ammonia nitrogen content, butyric acid production, and CP content reduction; it promoted bad fermentation of the silage.
