摘　　要：N-氨甲酰谷氨酸(NCG)作为一种新型的饲料添加剂,在牛、羊的营养调控中具有重要作用,主要表现在提高奶牛血浆一氧化氮(NO)含量、增加瘤胃微生物多样性、改善乳品质,增强奶牛机体抗氧化能力;改善公牛肉品质、降低尿氮和血液中尿素氮和氨的浓度,促进氨的排出和氨基酸的合成;提高绵羊的产羔率、改善限饲湖羊胎儿的肝脏炎症;促进哺乳山羊羔羊生长发育等方面。本文综述了饲粮中添加NCG对牛、羊生长性能、繁殖性能、免疫调节、泌乳性能和机体抗氧化影响的研究进展,讨论了基于牛、羊不同生产性能需求添加NCG的剂量选择策略,为应用NCG提高牛、羊的生产性能提供参考。As a new feed additive,N⁃carbamylglutamate(NCG)plays an important role in nutrient regulation of cattle and sheep,mainly by increasing plasma nitric oxide(NO)content,increasing rumen microbial diver⁃sity,improving dairy quality and enhancing antioxidant capacity of dairy cows.Improve the quality of male beef,reduce the concentration of urea nitrogen and ammonia in urine and blood,promote the discharge of am⁃monia and the synthesis of amino acids;increase lambing rate of sheep and improve liver inflammation of fetu⁃ses of restricted feeding Hu sheep;promote the growth and development of lactating goats and lambs.This pa⁃per proceeds as follow,the effects of dietary NCG on growth performance,immune regulation,reproductive performance,lactation performance and anti⁃oxidation of cattle and sheep were reviewed,and discussed the dose⁃selection strategy of adding NCG based on different performance requirements of animals,so as to pro⁃vide references for farmers to apply NCG to improve the performance of cattle and sheep.
