低蛋白日粮在反刍动物生产中的应用研究进展OA

The technology of low-protein diets has the potential to address challenges in industry including the current shortage of protein feed resources,low utilization efficiency of feed in livestock and poultry,and en-vironmental pollution caused by animal waste.This article studied the effects of applying low-protein diets in ru-minant production from four aspects,including the growth performance,lactation performance,blood biochemi-cal indicators,and nitrogen emissions based on reviewing domestic and international relevant literature.Results of many studies showed that low-protein diets can effectively reduce feed cost and significantly reduce nitrogen emissions while ensuring ruminant growth and product quality,achieving both economic and ecological ben-efits.The technology of low-protein diets is important for achieving sustainable development and improving quality and efficiency in modern animal husbandry.Future research should focus on the precise amino acid re-quirements for ruminants at different physiological stages and establishing a more comprehensive technology system of low-protein diets to drive the green,healthy,and sustainable development of animal husbandry,and to provide a scientific and theoretical basis for the application of low-protein diets in ruminant production.
