摘　　要：SPF动物即无特定病原体动物,是指不携带特定潜在感染或条件致病和对科学实验干扰大的病原实验动物。对成品饲料进行灭菌处理是保证SPF动物微生物质量的前提。不同灭菌方式对饲料微生物杀灭效果、营养成分及动物生产性能具有不同影响,因此在生产实践过程中须加以鉴别和选择。最常用的SPF动物配合饲料灭菌方式包括辐照灭菌和高压蒸汽灭菌,微波灭菌用于SPF动物配合饲料灭菌的相关报道较少。本文主要围绕SPF动物的营养需求、饲料中微生物控制、三种灭菌方式对饲料和动物生产的影响以及SPF动物饲料保存技术为切入点,对SPF动物饲料灭菌方式进行综述。SPF(Specific Pathogen Free)animals are specific pathogen-free animals,which refer to laboratory animals that do not carry specific potential infections or conditional diseases and pathogens that greatly interfere with scientific experiments.Sterilizing the finished feed is the premise to ensure the quality of SPF animal microorganisms.Different sterilization methods have different effects on the killing effect of feed microorganisms,nutrients and animal production performance,so they must be identified and selected in the production practice process.The most commonly used sterilization method for SPF animal formula feed include irradiation sterilization and high-pressure steam sterilization.There are few reports on the use of microwave sterilization for SPF animal formula feed sterilization.This paper focuses mainly on the nutritional requirements of SPF animals,the control of microorganisms in feed,the impact of three sterilization methods on feed and animal production,and the preservation technology of SPF animal feed,and summarizes the sterilization method of SPF animal feed.
