【摘要】：为了全面了解肉牛饲料营养的最新研究进展,作者查阅并总结了2015年关于肉牛饲料营养的国外文献报道,主要从精饲料、粗饲料以及精、粗饲料搭配3个方面进行了综述。精饲料主要包括蛋白质饲料和能量饲料,其中蛋白质饲料的营养研究主要侧重于不同蛋白质饲料对肉牛消化性能、生产性能、酮体特性和肉质以及瘤胃发酵的影响;能量饲料的营养研究侧重于不同类型及加工工艺对肉牛的生产性能、胴体特性以及瘤胃发酵特性的影响;粗饲料的营养研究主要集中于粗料来源及粗料的加工工艺对肉牛生产性能和消化性能两个方面的影响。另外,对精、粗饲料的搭配比例对肉牛生产性能、胴体特性、瘤胃发酵以及采食行为的影响也进行了综述。通过总结和分析肉牛饲料营养的国外研究成果,为中国肉牛业的快速发展提供一定借鉴。
[Abstract]:In order to understand the latest research progress of beef cattle feed nutrition, the author reviewed and summarized the foreign literature reports on beef cattle feed nutrition in 2015, mainly from concentrate feed, crude feed and essence. Three aspects of roughage collocation were reviewed. Concentrate feed mainly includes protein feed and energy feed. The nutritional research of protein feed mainly focuses on the digestibility and production performance of different protein feed to beef cattle. The effects of ketone body characteristics, meat quality and rumen fermentation, nutrition of energy feed on the performance, carcass characteristics and rumen fermentation characteristics of beef cattle were studied. The study on the nutrition of crude feed mainly focuses on the effects of raw material source and processing technology on the performance and digestibility of beef cattle, in addition, the proportion of fine and coarse feed to beef cattle has a great effect on the performance and carcass characteristics of beef cattle. The effects of rumen fermentation and feeding behavior were also reviewed. By summarizing and analyzing the foreign research results of beef feed nutrition, this paper provided some references for the rapid development of beef cattle industry in China.
