青贮饲料在关岭牛养殖中的应用研究进展OA

The growth and development rate of cattle is closely related to the intake of nutrients.Silage feed is widely used in the cattle industry due to its good palatability,long period of storage,rich nutrition,and wide source of raw materials.This article reviewed the progress on the application of silage feed in farming Guanling cattle by summarizing literature.The effects of silage feed on the production performance and eco-nomic benefits of farming Guanling cattle were analyzed.The reasonable use of silage feed can increase the daily weight gain of Guanling cattle,improve beef quality,reduce the costs of feed procurement for farming en-terprises by more than 15%,and increase the economic income of planters.Studies in the future should focus on elucidating the mechanism of regulating the quality of raw material for silage feed,promoting the low-cost technology,and formulating precise standards of farming suitable for Guanling cattle to promote the alleviation of the"competition between humans and livestock for grain"contradiction and consolidate the foundation for the sustainable development of the Guanling cattle industry.
