一种混合青贮饲料的制备及其在奶牛生产中的研究进展

Preparation of a kind of mixed silage and its research progress in cow production

青贮饲料是奶牛养殖中不可或缺的粗饲料,虽然青贮饲料具有营养丰富,适口性好,易消化吸收等特点,但部分青绿饲料的水分、糖分含量不适合青贮,所以可尝试通过混合青贮的方法来保证青贮成功。并且与单一青贮饲料相比,混合青贮饲料的来源广泛,通过不同青绿饲料的搭配使用,能取长补短,丰富饲料中的营养物质。本文从混合青贮饲料的制备入手,对不同饲料原料的作用和所占比例进行分析,并对其在奶牛生产中的应用进行综述。

Silage is an indispensable roughage for cow breeding.Although the silage has the characteristics of rich nutrition,good palatability and easy digestion and absorption,the moisture and sugar content of some green feeds are not suitable for silage,so we can try to ensure the success of silage through mixed silage.And compared with single silage,mixed silage has a wide range of sources.Through the use of different green feeds,it can complement each other and enrich the nutrients in the feed.This article starts with the preparation of mixed silage,analyzes the role and proportion of different feed materials,and summarizes their application in cow production.
