[Resorption of colostral gamma-globulins and detection of antibodies to Bact. rhusiopathiaesuis, S. cholerasuis and beta-hemolytic Esch. coli in newborn pigs].

Traced was the resorption of colostral globulins and the production of antibodies against Bacterium rhusiopathiae suis, S. choleraesuis, and beta-hemolytic Escherichia coli organisms in newborn pigs. It was found that in the newborn pigs that had not yet started sucking there were no gamma-globulins and specific antibodies against the agents mentioned above. Such were observed after the animals had begun to suck, the titers of antibodies reaching their peak levels by the 10th--15th hour (erysipelothrix and paratyphoid) and the 24th--48th hour (hemolytic Escherichia coli). As against their mothers the titer of the antibodies in the sucklings was two to four times as lower. The gamma-lactoglobulins are resorbed along the whole intestinal mucous membrane, however, resorption is most intense in the duodenum and the jejunum in the course of the first 2 days after farrowing; from the fifth day on it ceases.
