Pigs born of a Pietrain boar and pigs born of common boars were followed from birth to slaughter to study the potential effect the Pietrain breed on the expression of PMWS. The results of this study are in disagreement with some observations made by swine practitioners since no protective effect of the Pietrain breed was demonstrated. On the contrary, the likely role of parvovirus in PMWS pathogenesis was underlined: parvovirus infection in dams significantly increased the risk of PMWS in the offspring. On the other hand, low colostrums supply seems to be a clear predisposing factor for the expression of PMWS.
