African swine fever (ASF) outbreak has caused serious economic losses in Asia since 2018. As ASF is a new emerging disease, many farmers hesitate to raise pigs before biosafety procedures were evaluated to be effective. To support small-scale farms in resuming pig production, a comprehensive procedure, called the quadruple protection procedure (QPP), was tested in 35 small farms which had been confirmed with African swine fever virus (ASFV). The QPP takes care of the farms' construction, environmental disinfection, regular immunization, and feed quality. Qualified daily management was supplemented as well. During a one-year survey four disinfectants and one piece of equipment were used in higher frequency. A 7- or 15-day empty period after the disinfection was suitable when it was combined with the rest of the protection measures from QPP. Totally 18,730 porkers and 3,006 sows were healthy by the end of the study with percentage of 100 and 98.8, respectively, indicating that QPP could protect pigs in small-scale farms from pathogens within China. This study developed an effective protective procedure system for small-scale farms to produce pigs under the risk of ASF outbreak.
自2018年以来，非洲猪瘟（ASF）疫情在亚洲造成了严重的经济损失。由于ASF是一种新出现的疾病，在生物安全程序被评估为有效之前，许多养殖户对养猪犹豫不决。为了支持小规模养殖场恢复生猪生产，在35个已确诊感染非洲猪瘟病毒（ASFV）的小型养殖场中测试了一种名为四重保护程序（QPP）的综合程序。QPP涵盖了养殖场建设、环境消毒、定期免疫和饲料质量等方面。还补充了合格的日常管理。在为期一年的调查中，四种消毒剂和一件设备的使用频率较高。消毒后7天或15天的空栏期与QPP的其他保护措施相结合时是合适的。到研究结束时，共有18730头育肥猪和3006头母猪健康，健康率分别为100%和98.8%，这表明QPP可以保护中国小规模养殖场的猪免受病原体侵害。本研究为小规模养殖场在ASF疫情风险下生猪生产开发了一种有效的保护程序系统。
