摘要 为了解华南地区规模化猪场保育阶段猪猪瘟疫苗免疫后的抗体情况,文章采用阻断ELISA方法检测华南地区26个规模化猪场保育猪的375份血清样品。结果显示,猪瘟抗体免疫合格率90.9%(341/375),平均阻断率57.3%,抗体离散度21.2%,其中只进行了一次免疫的猪场,猪瘟抗体免疫合格率89.7%(287/320),平均阻断率56.5%,抗体离散度21.8%,二次免疫后的猪场,猪瘟抗体免疫合格率98.2%(54/55),平均阻断率62.6%,抗体离散度15.7%。可见华南地区保育阶段猪猪瘟抗体免疫合格率、离散度和平均阻断率水平较为理想,且进行二免的猪场免疫合格率、平均阻断率、离散度方面明显优于只进行了一次免疫的猪场,说明猪瘟的强化免疫是必要的。
