猪场猪伪狂犬病调查及免疫净化

Investigation and purification of pseudorabies in large-scale pig farms

为掌握种猪场、规模猪场猪伪狂犬病免疫现状与野毒感染情况,对辖区内9个猪场开展血清学抗体检测。结果显示,9个猪场中有7个存在野毒感染,隐性带毒普遍,基因缺失苗免疫合格率为96.9%。培育健康猪群、加强净化、科学免疫势在必行。

In order to master the immunization status and wild virus infection rates of porcine pseudorabies in the breeding pig farms and large-scale pig farms, the serologic identification test have been applied to 9 farms in the writer＇s area. The results showed that, 7 out of 9 farms were infected with wild virus which meant recessive infection was a mainly symptom in large-scale pig farms, and the pseudorabies （gB gene） antibody qualified rate reached 96.9% on average. It is imperative to carry out scientific immunization, cultivate healthy pigs and strengthen purification of epidemic disease.
