which coincide with the present study.
Since new-born piglets are immunologically immature
and the time lag before the immune system fully develops
covers a minimum period from birth until weaning,
piglets are dependent on sows for immune protection
during this period. The immunoglobulins in colostrum are
rapidly taken up by non-specific pinocytosis into the
enterocytes of the small intestine of new born piglets
and localized in vacuoles
