黑龙江某养猪户仔猪零星发病死亡，经PCR诊断为亚临床猪瘟。采集了60头母猪血，采用间接ELISA试剂盒检测60头母猪猪瘟免疫抗体水平。结果表明，该户母猪猪瘟免疫抗体水平较低，免疫抗体合格率仅为3.3%。因此，母猪免疫失败是导致仔猪散发猪瘟的主要原因。

Some piglets died in a pig farm sporadically, and diagnosed as subclinical swine fe-ver by a PCR test. Blood samples were collected from 60 sows for detecting immune antibody levels of swine fever. Results showed that swine fever antibody levels were low after vaccination in sow, the qualified rate of immune antibody is only 3.3%. Therefore, immune failure to swine fever in sows was the main reason caused swine fever occur sporadically in these piglets herd.
