湖南省部分原种猪场主要繁殖障碍性疫病的调查

为了解湖南省原种猪场主要繁殖障碍性病原感染情况及免疫抗体水平。从2011年开始,对我省部分原种猪场进行采样;每年监测5个原种猪场,连续4年,共采血清样品900份、扁桃体样本888份。样品进行了猪瘟病毒(CSFV)、猪繁殖与呼吸综合征病毒(PRRSV)、高致病性猪繁殖与呼吸综合征病毒(HP-PRRSV)、伪狂犬病病毒(PRV)、猪圆环病毒2型(PCV-2)、猪细小病毒(PPV)病原检测。结果显示,CSFV、PRRSV、HPPRRSV、PRV、PCV-2和PPV在我湖南原种猪场存在不同程度的感染,病原阳性率分别为0.12%、2.78%、0.45%、5.33%、9.02%和13.5%。血清样品进行了CSFV、PRRSV、PRV(gB)、PCV-2抗体检测,合格率分别为84.9%、90.6%、93.3%合100%。各猪场根据自身情况,加大监测力度,适时开展动物疫病净化工作,并采取严格的生物安全措施,从源头控制疫病的发生。

Investigation on Primary Reproductive Disturbance Diseases in Partial Pig Breeding Farms of Hunan Province

In order to understand the infection of the primary eproductive disturbance diseases and the im-mune effects in pig breeding farms in Hunan province,since 201 1,sampling in part of pig breeding farms in Hunan province.Surveille five pig breeding farms each year for the four year in a row,sampling 900 ser-um samples and 888 tonsil samples.Detect the antigen of CSFV,PRRSV,HP-PRRSV,PRV,PCV-2,PPV. The result showed that positive rate of antigen were 0.12%,2.78%,0.45%,5.33%,9.02%,13.5%.The positive rate of CSF,PRRS,PR,PC,antibody were 84.9%,90.6%,93.3%,100%.The pig breeding farms should depending on its own situation,Increase the intensity of monitoring,developing animal disease cleanup and adopt strict biosecurity measures control the disease at source.
