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.
