一例规模化猪场流行性腹泻病的诊断与防控风险分析

Risk Analysis of Diagnosis and Prevention and Control of Epidemic Diarrhea in a Large-Scale Pig Farm

2022年2月4日,广西壮族自治区某规模化猪场妊娠母猪陆续出现水样腹泻、不吃或少吃料的临床症状,2022年2月6日,产房仔猪出现呕吐、水样腹泻,怕冷扎堆,脱水严重,且传播速度快。通过试剂盒快速检测和实验室检测,诊断为猪流行性腹泻病。针对检测结果对猪群进行紧急疫苗接种和药物治疗,并对此次疫情的发生和发展过程进行防控风险点分析,发现养猪场在生物安全方面存在较大的风险点,通过整改并采取严格的生物安全管理措施后,母猪群发病情况得到缓解,仔猪腹泻窝数下降,猪群趋于稳定,生产成绩逐步恢复。通过对此次案例的分析探讨,为规模化猪场对猪流行性腹泻病的发现和防控提供临床经验,同时增强对流行性腹泻病的风险预警意识,健全规模化猪场对流行性腹泻病的风险预警机制。

On February 4th,2022,pregnant sows in a large-scale pig farm in Guangxi Zhuang Autonomous Region successively showed clinical symptoms of watery diarrhea,no or less feeding.On February 6th,2022,piglets in the delivery room appeared vomiting,watery diarrhea,fear of cold piling up,severe dehydration,and rapid transmission.Swine epidemic diarrhea was diagnosed by rapid detection of kits and laboratory tests.According to the test results,the pig herds were given emergency vaccination and drug treatment,and the risk points of prevention and control were analyzed in the occurrence and development process of the epidemic.It was found that there were large risk points in biosafety.After rectification and strict biosafety management measures were taken,the incidence of sows was alleviated,the number of piglets with diarrhea decreased,the herd tended to be stable,and the production performance gradually recovered.Through the analysis and discussion of this case,it provided clinical experience for the discovery and prevention and control of porcine epidemic diarrhea in large-scale pig farms,enhanced the awareness of risk early warning of epidemic diarrhea,and improved the risk early warning mechanism of epidemic diarrhea in large-scale pig farms.
