To clarify the pathogenicity of boar semen,Classical swine fever virus(CSFV),Porcine reproductive and respiratory syndrome virus(PRRSV),Pseudorabies virus(PRV),Porcine circovirus type 2(PCV-2) and Bovine viral diarrhea virus(BVDV) were detected from boar semens collected from clinical and healthy pig farms.The detections showed that infection rate of CSFV,PRRSV,PRV,PCV-2 existed in clinical pig farms with 30.0%,50.0%,4.0% and 30.0%,while a lower infection accounted for 4.0%,20.0%,0.0% and 8.0% in healthy pig farms,respectively.It indicated strongly that the boar played a role in the occurrence and spread of diseases.
