Investigation on Porcine Epidemic Diarrhea and Porcine Transmissible Gastroenteritis in Guangxi 2011

为研究广西2011年猪群腹泻情况,对34个县144个不同养殖规模猪场进行了猪群腹泻性疫病流行病学调查,并采集216份粪便病料,采用RT-PCR方法进行病原检测。结果显示,猪流行性腹泻阳性率27.78%(60/216),猪传染性胃肠炎阳性率7.41%(16/216)。根据不同养殖规模的猪场进行统计,以存栏母猪50头以下的规模猪场发病率和病死率最高,分别为11.64%和1.85%;对不同年龄段的猪群进行统计,以哺乳仔猪的发病率和病死率最高,分别为11.98%和2.93%。结果表明,广西的猪群腹泻病原以流行性腹泻病毒为主,哺乳仔猪发病和死亡较多。
