为观察猪瘟脾淋苗限断多种基因亚群带毒母猪垂直传播的效果.选择5个有代表性的规模化猪场为试验点,分别将3种猪瘟带毒母猪(Subgroup1l,Suhgroup2.2,Subgroup2.3 )随机分成试验组和对照组.试验组采用猪瘟脾淋苗2头份免疫,对照组采用猪瘟细胞苗4头份免疫.采用酶联免疫吸附试验检测带毒母猪所产仔猪的猪瘟抗原状况.接受猪瘟脾淋苗免疫的带毒母猪Subgroup2.1,Subgroup2.2和Subgroup2.3所产仔猪的抗原阳性率分别为20.75%,18.75%,20.93%.明显低于对照组母猪所产仔猪的抗原阳性率(51.02%,44.83%,48.78%)猪瘟脾淋苗免疫多种基因亚群带毒,母猪对阻断垂直传播有很好的效果.
