乳酸菌益生特性及在猪生产中应用研究进展

摘要

Bacterial resistance and drug residue problems are concerned by people,searching antibiotic alter-natives has become a hot research topic.Lactic acid bacteria have many good characteristics,producing an-tibacterial materials,inhibiting or killing intestinal pathogenic bacteria,competing adhesion sites,regula-ting intestinal mucosal immunity,improving balance of intestinal flora,and promoting pig healthy.It have been considered to be one of potential antibiotic substitutes.This article reviewsed biological characteris-tics of lactic acid bacteria,probiotic functions,and the application in pig production.%病原菌耐药性和药物残留问题日益受到人们的关注，寻找饲用抗生素替代品已成为研究热点。乳酸菌具备诸多益生特性，可代谢产生抑菌物质，抑制或杀死肠道病原菌，与病原菌竞争肠黏膜黏附位点，调节肠道黏膜免疫，维持肠道屏障功能，改善肠道菌群平衡，改善猪只健康，已成为饲用抗生素潜在的替代品之一。论文综述了乳酸菌生物学特性、益生作用和在猪生产中的应用。
