青贮饲料在关岭牛养殖中的应用研究进展
Progress on the application of silage feed in farming Guanling cattle
牛的生长发育速度与所摄入的营养物质密切相关,青贮饲料凭借其适口性好、贮存期长、营养丰富及原料来源广泛等优势被广泛应用于养牛业。本文综述了青贮饲料在关岭牛养殖中的应用,分析青贮饲料对关岭牛生产性能和养殖经济效益的影响,合理使用青贮饲料可以提高关岭牛的日增重、提升牛肉品质,并且可以降低养殖企业饲料采购成本15%以上,提高种植户的经济收入。未来研究应着重解析青贮原料质量调控机制、低成本技术推广模式,并制定适配关岭牛的精准饲养标准,推动缓解“人畜争粮”的矛盾,夯实关岭牛产业可持续发展基础。
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 economic 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 enterprises 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.
