摘要
对全省各地猪群中细小病毒抗体的情况进行了调查。共调查2458胎,其中引起繁殖障碍的有1071胎,占调查总数的43.5％;用血凝抑制试验检查383头份血清,其中阳性反应336份,占被检总数的87.73％。进一步证明猪细小病毒病是引起我省母猪繁殖障碍的主要病因。
From 1990 to 1992, We investigated Pig Parvovirus (ppv) in different areas of Hubei province on the basis of its epidemiological characteristics and clinical symptoms. The results showed that 1071 of 2458 pigs investigated had signs of reproductive failure and morbidity was 43. 5%. Haemagglutinatipn inhibition (HI)test showed that 336 of 383 sera were positive,and positive rate was 87. 73%. The results proved further that PPV was the main cause of reproductive failure in pigs in Hubei provine.
