摘要/Abstract

摘要： 猪繁殖障碍性疫病严重危害养猪业的发展,为了查清山西省这些疫病的流行情况,对全省8个地市42个规模化种猪场进行了流行病学调查,发现因母猪繁殖障碍病造成死亡的仔猪数平均可以占到总产仔数的13.77%,同时采集病料组织257份,不同日龄猪群血清1776份,用不同病原的PCR和ELISA试剂盒对猪瘟、猪繁殖与呼吸综合征、猪伪狂犬病和猪圆环病毒2型等进行了病原和抗体检测,结果表明,猪瘟病毒感染率为28.4%,抗体阳性率为57.55%;猪繁殖与呼吸综合征感染率为3.89%;猪繁殖与呼吸综合征变异株感染率为39.69%,抗体阳性率为44.99%;猪伪狂犬病病毒感染率为10.12%;gE抗体阳性率为2.98%,gB抗体阳性率为76.35%;猪圆环病毒2型感染率为15.18%,抗体阳性率为56.98%,证明山西省种猪场4种疫病感染较为严重,并且常常发生混合感染,为今后山西省防控这些疫病提供了依据。

Abstract: Porcine reproductive disturbance diseases have affected the development of pig industry seriously. In order to investigate the epidemics of those diseases in Shanxi province, pigs from 42 breeding farms in 8 cities were selected. It was found that piglet death rate accounted for 13.77% because of sow reproductive disturbance diseases. Then 257 tissues and serum from 1776 diseased pigs at different ages were got and the pathogens and antibodies for swine fever, swine blue ear disease, swine pseudorabies and swine circovirus type 2 were analyzed by PCR and ELISA. The results showed that the swine fever virus infection rate was 28.4% and antibodies positive rate was 57.55%; porcine reproductive and respiratory syndrome virus and its variants infection rate was 3.89% and 39.69%, respectively, and antibody positive rate was 44.99%; swine pseudorabies virus infection rate was 10.12%, gE antibody positive rate was 2.98% and gB antibody positive rate was 76.35%; swine circovirus type 2 infection rate was 15.18% and antibody-positive rate was 56.98%. It was suggested that single and mixed infections of those four kinds of diseases were occurred seriously in pig breeding farms in Shanxi province, which supplied the evidence for those diseases prevention and control in Shanxi province.
