The purpose of the present study was to investigate porcine circovirus (PCV) shedding into the milk of sows. Colostrum was collected from 33 sows. PCV1 was isolated from four of 33 milk whey samples. PCV1 DNA was detected by polymerase chain reaction in three of these samples and in three of 10 milk cell samples. PCV2 was also isolated and detected from every single milk whey sample. These results showed that PCV1 and PCV2 were shed into the milk of sows and suggest that PCV can be transmitted to offspring by an oral route through milk.
本研究的目的是调查猪圆环病毒（PCV）在母猪乳汁中的排出情况。从33头母猪采集了初乳。在33份乳清样品中的4份中分离出了PCV1。通过聚合酶链反应在其中3份样品以及10份乳汁细胞样品中的3份中检测到了PCV1 DNA。在每一份乳清样品中也都分离并检测到了PCV2。这些结果表明PCV1和PCV2会排到母猪的乳汁中，提示PCV可通过乳汁经口途径传播给后代。
