低蛋白饲粮在畜禽生产中的应用进展OA

The two major challenges faced in domestic livestock and poultry production today remain envi-ronmental pollution and protein raw material scarcity.To address these two issues,non-grain proteins are generally chosen to replace some of the protein and other nutrients in the diet.This approach not only reduces the import of protein raw materials,alleviates the excretion of nitrogen and phosphorus from live-stock and poultry,and mitigates environmental pollution,but also enhances cost-effectiveness.In recent years,low protein diet feed technology has been widely applied in the livestock and poultry breeding indus-try.This article briefly describes the application of low-protein diets in livestock and poultry production,analyzes their effects on livestock and poultry growth performance,reproductive performance,slaughter per-formance,and nitrogen and phosphorus metabolism,explores the existing problems and challenges of low-protein diets,and looks forward to their future development prospects,providing a theoretical basis for the promotion and application of low-protein diets.
