摘　　要：近期,湖南某规模化种猪场持续发生以产房仔猪腹泻为主要特征疾病,根据临床症状及经验,该场一直认为是猪流行性腹泻病毒引起,但经过对母猪产前免疫、返饲等措施进行防控,效果仍较差,为查明原因,采用RT-PCR方法对送检的20份腹泻粪便拭子样品进行猪传染性胃肠炎病毒、猪流行性腹泻病毒和猪轮状病毒病毒检测;结果显示,其中17份为猪轮状病毒核酸阳性,另外两种病原均为核酸阴性,提示该猪场引起仔猪腹泻的病原为猪轮状病毒,加上饲养管理方面存在的不足,导致该病在猪场的持续发生。近年来,由于猪流行性腹泻病毒和猪传染性胃肠炎病毒引起的腹泻较多,从而忽视对其他引起腹泻的病毒性疾病认识,延误了治疗,加大了损失,值得相关从业人员注意和借鉴。Recently,a large-scale pig breeding farm in Hunan Province has been experiencing persistent diseases character-ized by piglet diarrhea in the delivery room.Based on clinical symptoms and experience,the farm has always believed that it is caused by porcine epidemic diarrhea virus.However,after measures such as prenatal immunization and re feeding of sows,the effect is still poor.To identify the cause,RT-PCR was used to detect porcine infectious gastroenteritis virus,porcine epidemic diarrhea virus,and porcine rotavirus virus in 20 fecal swab samples submitted for testing;The results showed that 17 of them were positive for porcine rotavirus nucleic acid,while the other two pathogens were negative for nucleic acid,indicating that the pathogen causing piglet diarrhea in the pig farm was porcine rotavirus.In addition,there were deficiencies in feeding manage-ment,which led to the continuous occurrence of the disease in the pig farm.In recent years,due to the high incidence of diarrhea caused by porcine epidemic diarrhea virus and porcine infectious gastroenteritis virus,awareness of other viral diseases that cause diarrhea has been neglected,treatment has been delayed,and losses have increased.This is worthy of attention and refer-ence by relevant practitioners.
