牧草混合青贮技术及其在动物生产中的应用

Forage grass mixed silage technology and its application in animal production

牧草是草食动物重要的粗饲料来源,青贮可降低牧草体积,有利于贮藏。然而一些牧草存在水分高、可溶性碳水化合物含量低等问题,对牧草单一进行青贮发酵品质较差。混合青贮技术可发挥不同原料的特性,形成互补,有效改善牧草青贮品质。本文分析了混合青贮品质的影响因素,归纳了牧草混合青贮技术的类型及其在动物生产中的应用。

Forage grass is an important source of roughage for herbivores.Silage can reduce the volume of grass and facilitate storage.However,some grass has the problems of high water content and low water soluble carbohydrate content,and the fermentation quality of grass silage directly is poor.The mixed silage technology can play the characteristics of different raw materials,form a complementation,and effectively improve the quality of grass silage.This paper analyzed the affecting factors of mixed silage quality,summarized the types of mixed silage technology and its application in animal production.
