Abstract

Because of the epitheliochorial nature of the porcine placenta, the new-born piglet must acquire maternal immunoglobulins from ingested colostrum and milk for passive immune protection until the immune system of the piglet becomes fully developed. Concentrations of IgG in piglet plasma depend on the amount of colostrum ingested, IgG concentrations in colostrum and the timing of gut closure (when intact IgG can no longer be absorbed by the gastro-intestinal tract of the piglet). Much of the available information concerning IgG absorption by the piglet and the mechanism and timing of gut closure has been derived from studies using artificially-fed piglets. It is now recognised that, in additio..
