Abstract：In recent years，the beef cattle breeding industry in Liulin County has been developed to different extents，and the demand for high-quality feed has increased significantly with the expansion of the scale of cattle breeding. At present，with the continuous development of cattle breeding industry，the higher nutritional advantages of silage feed are gradually brought into play. Through silage treatment of Corn Straw，the palatability of feed is increased，the content of crude fiber in corn Straw is reduced，and it is better utilized by beef cattle，it is very helpful to increase the yield and quality of beef cattle. This paper mainly discusses the application of silage in beef cattle breeding and the analysis of breeding benefit.

Keywords：silage，beef cattle breeding，application

0引言

当前随着社会经济的发展进程不断加快，肉牛养殖产业逐渐发展壮大，已成为很多养殖户发家致富的支柱性产业。农业生产中会产生大量的农作物秸秆，对这些农作物秸秆进行适当的处理，发展青贮饲料，进一步释放秸秆的营养价值，保存秸秆的营养物质，同时减轻秸秆中粗纤维的含量，更有利于被肉牛消化和利用，增加肉牛的产量和品质。将青贮饲料应用到肉牛养殖领域，有效降低养殖成本。另外，开展青贮玉米种植、生產青贮饲料也能提高土地利用效率。

1青贮饲料概念

青贮饲料是指将天然的植物性饲料进行适当粉碎，经过排气压实密封处理后，在厌氧条件下进行一系列发酵处理生产的发酵饲料。发酵处理后降低饲料的pH值，实现对秸秆饲料的长期保存，同时也能保持饲料中的营养价值，更好地满足动物的生长发育所需。当前青贮饲料加工技术已在肉牛养殖领域得到广泛应用。……
