Improving the efficiency and production of grazing ruminants to support food and fiber production, while reducing the environmental footprint and meeting the welfare needs of the animals, is important for sustainable livestock production systems. Development of new technologies that can improve the efficiency of nitrogen (N) utilization in ruminants, and that are effective and safe, has important implications for ruminant livestock production. N-carbomoylglutamate (NCG) is a functional micronutrient that stimulates endogenous synthesis of arginine, which can improve survival, growth, lactation, reproductive performance, and feed efficiency in mammals. There is a growing body of evidence to support the potential of dietary NCG supplementation to improve the productive capacity and N utilization efficiency of ruminants. This review summarizes the current literature on the effects of dietary supplementation with NCG in ruminants and impacts on production and potential to reduce the environmental footprint of farmed ruminant livestock. The current literature highlights the potential for commercial application in ruminant livestock to improve productivity and N utilization efficiency.
提高放牧反刍动物的效率和产量以支持食物和纤维生产，同时减少环境足迹并满足动物的福利需求，对可持续畜牧生产系统至关重要。开发能够提高反刍动物氮（N）利用效率、有效且安全的新技术，对反刍动物畜牧生产具有重要意义。N-氨甲酰谷氨酸（NCG）是一种功能性微量营养素，可刺激精氨酸的内源性合成，从而提高哺乳动物的存活率、生长、泌乳、繁殖性能和饲料效率。越来越多的证据支持日粮添加NCG可提高反刍动物生产能力和氮利用效率的潜力。本文综述了当前关于日粮添加NCG对反刍动物的影响及其对养殖反刍动物生产和减少环境足迹潜力的文献。当前文献强调了NCG在反刍动物畜牧中商业应用以提高生产力和氮利用效率的潜力。
