摘　　要：为了了解2021年新疆部分地区猪圆环病毒2型(PCV2)的抗体水平,以期为该病的科学防控提供参考。本试验采用间接ELISA (酶联免疫吸附试验)对来自3个地区7个猪场的201份血清样品进行PCV2抗体检测。结果显示,PCV2抗体平均阳性率为87.06%(175/201),高于国家规定标准(70%),抗体的平均离散度为0.77;在调查的7个规模化猪场中,所有猪场的PCV2抗体阳性率均达到国家规定标准,表明新疆地区猪PCV2的免疫效果较好,但一些猪场的PCV2抗体的S/P值变异系数偏大,免疫抗体S/P值参差不齐,需要对现有免疫程序进行调整和完善。本试验为新疆地区猪PCV2的防控工作提供一定的参考。In order to understand the antibodies against porcine circovirus type 2(PCV2)in some areas of Xinjiang in 2021,so as to pro vide reference for scientific prevention and control of the disease.In this study,201 serum samples from 7 pig farms in 3 regions were detected for PCV2 antibody by indirect ELISA(enzyme linked immunosorbent assay).The results showed that the average positive rate of antibodies against PCV2 was 87.06%(175/201),which was higher than the national standard(70%),and the average dispersion was 0.77.In the 7 large-scale pig farms investigated,the positive rate of PCV2 antibodies in all pig farms reached the national standard,in-dicating that the immune effect of PCV2 in Xinjiang was good,but the S/P value variation coefficient of PCV2 antibodies in some pig farms was too large,and the S/P value of the antibodies was irregularity,so the current immune program needed to adjust and improve.This experiment provided some reference for the prevention and control of PCV2 in Xinjiang.
