Summary Porcine circovirus type 3 ( PCV 3) was detected in Shandong, China. One hundred and thirty‐two of 222 (59.46%) samples were PCV 3 positive, while 52 of 132 (39.39%) samples were co‐infected with PCV 2. There were no clinical signs of infection in either multiparous sows or live‐born infants. Two strains of PCV 3 were indentified from natural stillborn foetuses. Phylogenetic analysis showed the two strains of PCV 3 are 96% identical to the known PCV 3/Pig/ USA (KX778720.1, KX966193.1 and KX898030.1) and closely related to Barbel Circovirus. Further studies of the epidemiology of PCV 3 and the co‐infection with PCV 2 are needed.
