Differential Diagnosis and Prevention and Control of Porcine Rotavirus Disease

Abstract:

Recently,a largescale pig breeding farm in Hunan Province has been experiencing persistent diseases characterized 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 management,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 reference by relevant practitioners.
