【摘要】：调查江苏某集约化管理的大型种猪场的仔猪腹泻情况及分析病因,为有效防控仔猪腹泻提供参考。通过对该场腹泻仔猪的临床症状、病理变化进行观察、记录,对采集的发病仔猪病料进行细菌学和病毒学检查以及细菌的药敏试验,并统计、分析仔猪腹泻发病的主要原因。结果发现在临床上观察到仔猪发生严重的呕吐、腹泻和脱水症状,病理变化主要出现在胃肠道。腹泻主要发生于3~19日龄的仔猪,症状随着日龄增大而逐渐减轻。病原体为大肠杆菌的病例占70.0%、猪流行性腹泻病毒(PEDV)占42.5%、猪传染性胃肠炎病毒(TGEV)占15.0%、A群轮状病毒(GARV)占2.5%。本场的腹泻以大肠杆菌和流行性腹泻病毒感染为主,也存在一定的传染性胃肠炎病毒和轮状病毒病的混合感染,故发生仔猪腹泻病时做多种病原检测很有必要。
[Abstract]:To investigate the diarrhea of piglets in an intensive management farm in Jiangsu Province and to analyze the causes of diarrhea, and to provide a reference for the prevention and control of diarrhea in piglets. The clinical symptoms and pathological changes of piglets with diarrhea were observed and recorded. The bacterial and virological tests and drug sensitivity tests were carried out to analyze the main causes of diarrhea in piglets. The results showed that severe vomiting, diarrhea and dehydration were observed in the piglets clinically, and the pathological changes mainly occurred in the gastrointestinal tract. Diarrhea mainly occurred in piglets at the age of 3 ~ 19 days, and the symptoms gradually decreased with the increase of age. The pathogens were Escherichia coli (E.coli), porcine epidemic diarrhea virus (PEDV) and porcine infectious gastroenteritis virus (TGEV), respectively, accounted for 70.0%, 42.5%, 15.0% and 2.5% respectively. Escherichia coli and epidemic diarrhea virus are the main causes of diarrhea in this field, and there are some mixed infections of transmissible gastroenteritis virus and rotavirus disease, so it is necessary to do a variety of pathogen detection in piglets with diarrhea disease.
