摘　　要：反刍动物对于蛋白质饲料的利用效率相较于单胃动物偏低,如何提高反刍动物氮素利用效率,保障动物健康生长显得尤为重要,文章综述了主要的瘤胃氮素利用微生物以及氮素利用微生物制剂对反刍动物生长和健康的影响,以期为提高反刍动物氮素利用率提供更多的参考依据。The utilization efficiency of ruminants for protein feed is low compared with that of monogas⁃tric animals,how to improve the nitrogen utilization efficiency of ruminants to ensure the healthy growth of animals is particularly important,this paper reviews the main rumen nitrogen utilization microorgan⁃isms as well as the impact of nitrogen utilization microbial preparations on the growth and health of rumi⁃nants,with a view to improving the nitrogen utilization rate of ruminants to provide more reference basis.
