Research Progress on Application of N-Carbamylglutamate in Cattle and Sheep Production
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.[Chinese Journal of Animal Nutrition,2024,36(5):2782-2792]
