Abstract: Amid the intensification of global pig production，the issues of antibiotic resistance and public health risks arising from antibiotic overuse have become increasingly prominent. Consequently，many countries have implemented policies to restrict antibiotic use while promoting the adoption of probiotics as a sustainable alternatives in animal husbandry. Probiotics serve multiple functions，including regulating gut microbiota，enhancing immunity， improving nutrient absorption，exerting antioxidant effects，and enhancing meat quality. Their application can significantly contribute to swine health and productivity. This paper reviews the historical development and current application of probiotics，analyzes recent research advances and industry supply?demand dynamics，and forecasts future trends. It aims to provide a comprehensive and updated perspective on the role of probiotics in sustainable and healthy pig production.

摘要： 随着全球生猪养殖的集约化发展，抗生素滥用导致的耐药性与公共卫生问题日益突出，各国纷纷出台限抗政策，同时推动益生菌作为绿色替代品在养殖中的应用。益生菌拥有调节肠道菌群、增强免疫、提高养分吸收、抗氧化、改善肉品质等多重机制，使用益生菌能显著促进猪只健康与生产性能。该文回顾益生菌的发展历程、应用现状，分析近年来日益增长的益生菌相关研究成果和益生菌的产业供求关系等数据，预测益生菌未来发展趋势，旨在为益生菌应用于生猪健康养殖提供一个全新的更全面的认识。
