Boosting piglet immunity
with colostrum
Colostrum is not only the main source of energy for piglets,
but it also provides passive immunity.
BY JENNIFER MAURIN AND SÍGFRID LÓPEZ

The consumption of colostrum by piglets is crucial
to their survival during the lactation period, from the
moment they are born until they are weaned. The animal's survival chances during this critical period are
hindered by inadequate colostrum production by the
sow or due to its insufficient consumption by the piglet. Colostrum is not only the main source of energy,
but crucially, it also provides passive immunity to piglets that are only partially immunocompetent at birth.
Traditionally, the efficiency of the immune system
has been evaluated by veterinarians rather than by nutritionists. Nevertheless, recent publications identifying dietary ingredients that modulate immune functions have
revealed new perspectives for nutritional strategies.

Enriched colostrum provides piglets with an
immune-boost from their first day of life.

Piglets are partially immunocompetent from the
moment they are born, more specifically from day 70
of gestation. But the piglet immune system is still immature and not yet fully developed at birth. Therefore,
complete protection is ensured by exposing piglets after
birth to high levels of pathogens, forcing their immune
systems to rapidly mature, in addition to the passive
transfer of maternal antibodies through the colostrum.
This transmission of maternal antibodies is crucial, as
the type of placenta in sows (epitheliochorial) doesn't
allow the transfer of immunoglobulins. Nevertheless,
piglets already have antibodies in their bloodstream at
birth, which they generate after encountering antigens
during the final month of gestation.
