摘要：为掌握猪群注射猪瘟疫苗后产生的免疫抗体水平及消长趋势，2016年1～12月对青海省4个生猪主产县每月采集猪血清样品采用ELISA方法进行了猪瘟免疫抗体水平监测。结果显示猪群的猪瘟免疫抗体水平全年都处于较高的水平，猪瘟抗体平均合格率为77.5%，规模场抗体水平高于散养户，其中5～6月份和11～12月即集中注射疫苗后1个月猪群的平均抗体水平达到最高，以后逐渐降低，3～4月和8～9月份达到最低值。

Abstract: In order to understand the level and trend of immune antibody produced by swine fever vaccine, the immune antibody level of swine fever was monitored monthly by ELISA method in 4 main pig breeding areas in 2016, in Qinghai province. The results showed that immune antibody level of swine fever was at a higher level in the whole year. The average qualified rate of immune antibody was 77.5%. The antibody level in the scale pig farms was higher than that in the household. The average antibody level reached the highest level winthin1 month after immunization, between May and June, November and December and then decreased gradually. The average antibody level reached the lowest level between March and April, August and September after immunization.
