摘要
采用血清学方法对贵阳地区部分种猪场、规模饲养场及农村散养户猪群分别进行PPV、PRV、PRRS、PCV及APP抗体水平监测。以乳胶凝集试验检测PPV抗体阳性率为0%(0/160);以间接ELISA检测PCV和PRRS的抗体阳性率分别为14%(28/200)和0.62%(1/160);以竞争ELISA检测PRV的gpI抗体阳性率为19.14%(36/188);以间接血凝试验检测APP的抗体阳性率为19.14%(36/188)。结果表明,PPV和PRRS似乎不是引起贵阳地区猪繁殖障碍的主要原因,而PRV和APP在非免疫猪群中的抗体阳性率较高,应引起该地区养猪业的高度重视。
The antibody levels against PPV,PRV,PRRS,PCV and APP were surveyed by serological methods in partial pig breeding farms, large scale farms and countryside individual farmers of Guiyang district. No PPV antibody was observed in pig herds by latex agglutination test. The positive rates of PCV and PRRS were 14% and 0. 62% respectively by indirect ELISA. The gpI antibody against PRV has been detected by competitive ELISA, accounting for 19. 14%. Meanwhile the positive rate of APP antibody also reached 19. 14% by indirect hemoagglutination assay. It seemed that the PPV and PRRS were not the main reasons for pig reproductive disturbanee,more attention should be paid to PRV and APP,because the antibody levels were higher in non-vaccinated pig herds of Guiyang district.
