Heritabilities for copy number variation of porcine endogenous retrovirus by a quantitative PCR.

Pigs (Sus scrofa) have been expected to have organs transplanted to humans, but porcine endogenous retrovirus (PERV) is one of the risks because the PERV has the possibility to get infected with human cells. Therefore, the pigs are required to have as low a PERV copy number as possible. In this study, firstly, we investigated the estimates of heritabilities for the PERV copy numbers in the Vietnamese native breeds.
