摘要 为了解四川省部分规模猪场口蹄疫免疫效果,笔者从四川省内川东、川南、川西、川北、川中5个片区的17个规模猪场采集血清样品1454份,采用液相阻断ELISA方法进行口蹄疫O型和A型免疫抗体检测。结果显示:FMD-O型抗体总阳性率为83.29%,FMD-A型抗体总阳性率为80.26%;17个规模猪场的FMD-O型、A型抗体场群免疫合格率均为76.47%;哺乳仔猪、保育猪、育肥猪、经产母猪、种公猪、后备猪的FMD-O型抗体阳性率分别为84.95%、68.67%、81.31%、94.23%、88.03%、100%,FMD-A型抗体阳性率分别为80.65%、60.96%、79.75%、93.53%、88.03%、100%。本试验表明,四川省规模化猪场口蹄疫免疫效果总体较好,但部分猪场的免疫抗体水平不高,因此规模猪场仍需加强监测和免疫,降低口蹄疫的发生风险。
