Derivation of PCV2-Free Pigs

It has been demonstrated that derivation of PCV2-free pigs can be achieved by cesarean-section and colostrum deprivation (Tucker et al., 2003). Segregated early weaning (SEW) techniques are also effective for derivation of PCV2-free pigs from PCV2-positive breeding herds (Opriessnig et al., 2004).
