乳酸菌益生特性及在猪生产中应用研究进展

Progress on Probiotics Characteristics of Lactic Acid Bacteria and Its Apllication 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。

Bacterial resistance and drug residue problems are concerned by people,searching antibiotic alternatives has become a hot research topic.Lactic acid bacteria have many good characteristics,producing antibacterial materials,inhibiting or killing intestinal pathogenic bacteria,competing adhesion sites,regulating 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 characteristics of lactic acid bacteria,probiotic functions,and the application in pig production.
