中国免疫猪群猪瘟抗体的监测分析

Surveillance and Analysis on the Antibody Level against Swine Fever Virus among Immunized Swinery in China

为了解中国区域免疫猪群猪瘟抗体的水平,以便科学地评估猪瘟疫苗免疫效果,为猪场提供合理的免疫程序,应用ELISA方法,对2016年采集的国内不同地区、不同猪群的17275份血清进行了猪瘟抗体水平的检测与分析。结果发现,猪瘟阳性血清13 064份,阳性率为75.62%;各区域猪瘟抗体水平相差不大,但不同饲养阶段猪群的猪瘟抗体合格率参差不齐,其中种猪群抗体水平较好,商品猪群猪瘟抗体水平高低不一。

The results showed that out of 17275 samples,13064 were positive for swine fever with a pos-- tive rate up to 75. 62% ; the antibody level of each region was not significantly differate of which at different raising periods was uneven, among which the breeding swilevel,while that of the commercial swine was different.
