A note on the selective uptake of serum proteins in piglets following dosage with porcine serum

Perry (1964) has shown that piglets failed to absorb homologousBrucella abortusantibodies, whereas they absorbed homologousSalmonella pullorumantibodies much more readily. WhenS. pullorumantibody was used, piglets showed marked differences in their efficiency of absorption. These differences existed whether the antibodies were administered in serum or in colostrum (Perry and Watson, 1967a, b). Moreover, they could not be entirely accounted for by variation in concentration of antibody in the dose, age at dosage, genetical effects or maternal effects (Perry and Watson, 1967a).
