| Abstract: | In order to understand the epidemic situation and changing pattern of swine viral diseases in Zhejiang Province, the detection of pathogens and anti-virus antibodies were carried out on the pathological materials and sera from large-scale pig farms in Zhejiang Province from 2017 to 2020,includingporcine reproductive and respiratory syndrome virus(PRRSV),swine fever virus(CSFV),pseudorabies virus(PRV) and porcine circovirus type 2(PCV2).The antibody results showed that the average positive rates of PRRSV,CSFV,PCV2,PRV gE/gI and PRVgB were 81.4%,83.6%,91.4%,36.1% and 94.3%,respectively.In different years, the antibody levels of CSFV and PCV2 have been rising steadily, and the antibody levels of PRRSV and PRV gE/gI have decreased significantly in 2020.The results of pathogen detection showed that PRRSV,CSFV,PCV2 and PRV infections were very prevalent, and the average positive rate of PRRSV,CSFV,PCV2 and PRV were 22.9%,2.5%,17.3% and 6.6%,among which the positive rate of PRRSV/PCV2 double infection was as high as 9.7%.Among different ages, the positive rates of PRRSV,PCV2 and CSFV in weaned pigs were the highest, followed by fattening pigs, while the positive rates of PRV in suckling piglets were the highest.In addition, the positive rates of CSFV,PCV2 and PRV decreased significantly from 2019 to 2020. |
