摘要 为探讨一种适合四川某猪场的口蹄疫免疫程序,根据猪场实际情况,我们对免疫程序进行了调整。采集调整前和调整后不同日龄猪的血清,分别用ELISA和IHA进行抗体检测,结果显示:免疫程序调整前3日龄、25日龄、50日龄、90日龄和120日龄猪的ELISA抗体阳性率分别为50%、30%、40%、50%、55%,IHA抗体阳性率分别为70%、54.54%、66.67%、70%和85%;调整后ELISA抗体阳性率分别为90%、35%、45.45%、61.11%和50%,IHA抗体阳性率分别为82.98%、83.33%、92.86%、95%和95%。调整前ELISA和IHA抗体平均阳性率分别为46.67%和71.67%,调整后分别为52.22%和88.49%,可见调整后的免疫效果明显优于调整前。调整后的免疫程序为:25日龄首免,50日龄二免,90日龄三免,以后每3个月免疫一次。
