新疆部分地区猪瘟病毒抗体水平检测及分析

Detection and Analysis of CSFV Antibody Level in Some Areas of Xinjiang

为了解2019—2020年新疆部分地区猪瘟病毒(CSFV)抗体水平,采用酶联免疫吸附试验(ELISA)法对采自6家规模化猪场不同类别猪群的1238份血清样品进行猪瘟(CSF)抗体检测与分析。结果显示,CSFV抗体平均阳性率为85.70%(1061/1238),高于国家规定标准(70%)。在各猪场中,B场的平均阻断率最高,为70.26%,D场的平均阻断率最低,为61.00%;D猪场的平均阻断率与A、B、C、E场存在显著差异(P<0.05)。各类别猪群中,繁殖母猪的平均阻断率最高,为74.05%,保育猪的平均阻断率最低,为50.91%;肥育猪的平均阻断率与哺乳仔猪、保育猪、后备猪、繁殖母猪、种公猪存在显著差异(P<0.05)。结果表明,6个猪场的猪瘟病毒抗体阳性率都能达到国家标准(70%),但哺乳仔猪、保育猪、肥育猪需要制定更加合理的免疫程序。

In order to understand the levels of CSFV antibodies in some areas of Xinjiang in 2019-2020,the author used an enzyme-linked immunosorbent assay(ELISA)method to test 1238 serum samples from different types of pig herds from 6 large-scale pig farms(CSF)Antibody detection and analysis.The results showed that the average positive rate of CSFV antibody was 85.70%(1061/1238),which was higher than the national standard(70%).Among all the pig farms,the average blocking rate of farm B was the highest,which was 70.26%,and the average blocking rate of farm D was the lowest,which was 61.00%;the average blocking rate of farm D was significantly different from that of A,B,C,and E Difference(P<0.05).In each type of pig herd,the average blocking rate of breeding sows was the highest,at 74.05%,and the average blocking rate of nursery pigs was the lowest,at 50.91%;there was a significant difference between breeding sows and breeding boars(P<0.05).The results showed that the positive rate of swine fever virus antibody in the 6 pig farms can reach the national standard(70%),but suckling piglets,nursery pigs,and fattening pigs need to develop more reasonable immunization procedures.
