龙岩市2015-2017年规模化猪场高致病性猪蓝耳病和猪瘟免疫抗体水平调查

Research on the immunoantibody levels against high pathogenic PRRS and CSF on large-scale pig farms of Longyan city during 2015 to 2017

为了解龙岩市2015-2017年规模化猪场高致病性猪蓝耳病和猪瘟疫苗免疫效果,并探讨高致病性猪蓝耳病和猪瘟退出强制免疫病种后,规模化猪场的防控情况。从龙岩市辖区7个县(市、区)规模化猪场采集猪血清样品,采用ELISA方法对免疫抗体进行检测。结果显示:龙岩市2015-2017年高致病性猪蓝耳病、猪瘟群体免疫抗体平均合格率均超出农业部70%以上的要求。2017年因高致病性猪蓝耳病和猪瘟退出强制免疫病种后,两种病的群体免疫抗体水平均有不同程度下降。

To understand the vaccine immune effect of highly pathogenic PRRS and CSF from 2015 to 2017, and explore the prevention and control situation on large-scale pig farms of Longyan city after withdrawing highly pathogenic PRRS and CSF from forced immunization diseases. In this study, pig serum samples were collected from large-scale pig farms in 7 counties （cities, districts） of Longyan city, and the immunoantibody levels were detected by ELISA. The results showed that the average qualified rate of highly pathogenic PRRS and CSF all exceeded the requirements of the ministry of agriculture by more than 70% during 2015 to 2017. The immunoantibody levels of group in both diseases declined to varying degrees after withdrawing highly pathogenic PRRS and CSF from forced immunization diseases.
