摘要/Abstract

摘要： 为掌握豫南地区规模化猪场中猪繁殖与呼吸综合征病毒（PRRSV）和猪圆环病毒2型（PCV2）疫苗免疫场猪群抗体水平和非疫苗免疫场猪群病原感染情况，试验利用ELISA方法对该地区猪群进行了PRRSV和PCV2抗体水平检测。结果表明，在疫苗免疫猪群中，PRRSV和PCV2抗体合格率分别为68.8%和58.7%，规模越大的猪场合格率越高，200~500头母猪规模场抗体阳性率最高（分别为76.8%和77.4%），50头母猪以下场最低（分别为48.3%和44.2%），种猪的合格率均最高，而育肥猪群合格率均最低。在非疫苗免疫猪群中，PRRSV和PCV2抗体阳性率分别为55.6%和65.3%，PRRSV抗体阳性率最低的是100~200头母猪规模场（46.5%），最高的是50头母猪以下规模场（68.8%），断奶仔猪和育肥猪群抗体阳性率均在71%以上；随猪场规模越大，PCV2抗体阳性率越低，200~500头母猪规模场抗体阳性率为41.4%，50~100头规模场和50头以下场的阳性率分别为78.9%和78.6%，种公、母猪的PCV2抗体阳性率最低（分别为37.5%和40.4%），断奶仔猪和育肥猪抗体阳性率较高（分别为82.2%和79.5%）。本研究反映了豫南地区猪繁殖与呼吸综合征（porcine reproductive and respiratory syndrome，PRRS）和猪圆环病毒病（porcine circovirus disease，PCVD）疫苗免疫猪场的疫苗免疫效果和非疫苗免疫猪场病原感染的实际情况和规律，为该地区PRRS和PCVD防制工作提供了理论依据和指导。

Abstract: In order to investigate antibody levels of porcine reproductive and respiratory syndrome virus (PRRSV) and porcine circovirus type 2 (PCV2) in porcine serum, we randomly collected from different sizes of farms in southern regions of Henan province, these pigs had or had not been vaccinated with PRRS and PCVD vaccine. The antibody levels of PRRSV and PCV2 were detected by ELISA in this article. The results showed that average qualification rates of antibodies of PRRSV and PCV2 were 68.8% and 58.7% in vaccinated farms,respectively,the larger farm, the higher qualified rate, which 200 to 500 sow pigs farm was the highest (76.8% and 77.4%,respectively) and under 50 sow pigs farm was the lowest (48.3% and 44.2%, respectively), which sow pig was highest and finishing pig was lowest. The results showed that average positive rates of PRRSV and PCV2 antibodie were 55.6% and 65.3% in no vaccinated farm, respectively, which average positive rate of PRRSV antibody in 100 to 200 sow pigs farm was lowest (46.5%), under 50 sow pigs farm was highest (68.8%), and growing pig and finishing pig were both more than 71%, which average positive rate of PCV2 antibody, the larger farm, the lower positive rate, 200 to 500 sow pigs farm was 41.4%, 50 to 100 sow pigs farm and under 50 sow pigs farm were 78.6% and 78.9%,respectively, and female and male sow pigs were lowest (37.5% and 40.4%,respectively), and growing pig and finishing pig were higher (82.2% and 79.5%, respectively). This research reflected the situation and the rule of the antibody levels of PRRSV and PCV2, these pigs had or not been vaccinated with PRRS and PCVD vaccine, and provided theoretical bases and guidances for prevention and control of PRRS and PCVD in southern regions of Henan province.
