缓释尿素在反刍动物生产中的应用效果及其影响因素分析
Application of Slow-Release Urea in Ruminant Production and Its Influencing Factors
摘要
Abstract
In ruminant farming,the addition of urea to low-protein diets can compensate for protein deficiencies.However,urea is hydrolyzed too rapidly in rumen,resulting in asynchronous release of ammonia and carbon skeletons,which hinders the effective synthesis of microbial crude protein(MCP).This not only leads to nitrogen nutrient waste but also contributes to environmental pollution.To address this issue,the application of slow-release technology improves urea utilization efficiency,promotes MCP synthesis,enhances animal production performance,and supports the realization of green and healthy animal husbandry.Based on their release mechanisms,slow-release urea can be categorized into physically coated urea,chemically synthesized urea derivatives,and urease inhibitors.This review summarizes the applications of different types of slow-release urea in ruminant production and the effects of factors such as dosage,coating materials,and dietary structure on their efficacy.The aim is to provide references for conserving protein feed resources and reducing environmental pollution.关键词
