摘要
试验主要通过连续追踪仔猪群PRV g E和g B抗体,分析抗体滴度、S/N值和阳性率,制定科学的免疫方式,评估Bartha株疫苗的免疫效果,为控制与净化PRV提供理论依据。结果表明,PRV疫苗首免日龄为9周,Bartha株疫苗控制PRV野毒感染仍有效果,免疫效果C组优于B组。
The experiment mainly tracks PRV gE and gB antibodies in piglets,through analyzing antibody titer,S/N value and positive rate,to formulate scientific immunization methods,evaluate the immune effect of the Bartha strain vaccine,and provide a theoretical basis for the control and elimination of PRV.The results showed that the age of first vaccine was 9 weeks.The Bartha strain vaccine still had an effect on the control of wild-type infection of PRV.The immune effect of group C was better than group B.
