【摘要】 随着规模化养猪的快速发展，烈性传染病造成的经济损失越来越大，而建立科学、高效的生物安全体系是有效预防和控制动物传染病的重要措施。在养猪生产过程中采取生物安全措施可以阻止或减少外部病原的引入(外部生物安全)及病原在养殖场内的传播(内部生物安全)。同时，科学的生物安全体系还有助于提高养殖生产效率、减少药物和疫苗的使用量。文章综述了目前国内养猪业主要采取的生物安全措施，同时系统分析了美洲和欧洲国家生物安全措施在猪场应用的发展历程，以期为完善我国养猪业生物安全防控体系提供借鉴。更多还原

【Abstract】 With the rapid development of the pig industry, the losses caused by fatal infectious diseases are increasing, and the establishment of a scientific and efficient biosafety system is an important measure to effectively prevent and control animal infectious diseases. Biosafety measures in pig production can prevent or reduce the introduction of external pathogens(external biosafety) and the spread of pathogens in the farm(internal biosafety). At the same time, scientific biosecurity systems can also help improve the efficiency of farming production and reduce the use of drugs and vaccines. In this paper, the main biosafety measures adopted in domestic pig industry were reviewed, and the development of biosafety measures applied in pig farms in America and Europe was systematically analyzed, in order to provide reference for improving the biosafety prevention and control system of pig industry in China.更多还原
