摘　　要：与传统尿素相比,包被缓释尿素具有很多优势,能有效维持瘤胃氨浓度,提高动物对氮的利用率,提高微生物蛋白的合成效率;促进瘤胃发酵,提高动物生长性能;降低养殖场氨的代谢排放,减少环境污染。本文介绍了近几年国内外的包被缓释尿素技术,并对其评价方法以及动物试验效果进行总结,以期为包被缓释尿素相关研究提供参考。Compared with traditional urea,coated slow-release urea has many advantages,which can effectively maintain the rumen ammonia concentration,improve the utilization efficiency of nitrogen,improve the synthesis efficiency of microbial protein,promote rumen fermentation,increase animal growth performance,reduce ammonia metabolism discharge of livestock farm,and reduce environmental pollution.This review introduced the technology of coated slow-release urea in recent years,and summarized the evaluation methods and animal experiment effectiveness,which provided reference for the research of coated slow-release urea.
