冀鲁豫交接地区不同规模猪场高致病性猪蓝耳病血清学调查

Serology Investigation of Porcine Reproductive and Respiratory Syndrome from Different Large-scale Pig Farms in the Junction Areas Hebei-Shandong-Henan Provinces

为了解冀鲁豫三省交接地区不同规模猪场高致病性猪蓝耳病免疫抗体水平情况,为高致病性蓝耳病强免工作提供数据支持。2012—2014年3年间,通过ELISA方法对冀鲁豫三省交接地区不同猪场的2 829份血清进行高致病性蓝耳病抗体水平检测。结果显示,不同饲养阶段、不同养殖规模、不同年份猪的免疫抗体水平均存在一定差异。这说明这一地区猪群还有待加强定期抗体检测和高致病性猪蓝耳病疫苗免疫。

To understand antibody levels of Porcine Reproductive and Respiratory Syndrome and to provide basis data for mandatory vaccination program in different large-scale pig farms of the junction areas Hebei-Shan dong-Henan provinces. Antibody level of PRRS have been detected in 2 829 serum samples by ELISA method for the period 2012 through 2015. Results show that antibody level were different in different scale-farm, different breeding stage and pig of different age. This suggests pigs are still to be strengthen regular antibody detection and enhance PRRS vaccine immunity in the region.
