Abstrakt		The gastrointestinal tract of newborn piglets is permeable for intact immunoglobulins ingested with the colostrum. The duration of this passage was investigated by administering hourly rations of 25 ml of either porcine or bovine colostrum for 6, 12, 18 or 24 hrs after birth. The plasma concentrations of the subclasses porcine IgG, IgM and IgA or bovine IgG1, IgG2, IgM and IgA were determined at 12, 18 and 24 hrs after birth and on days 3 and 6. Feeding periods of 6 hrs resulted in plasma Ig levels of the same order of magnitude as observed in natural rearing. These levels were not substantially increased after prolonged feeding. The 6 percent gain from 6 to 12 feedings seen with porcine colostrum as compared with a gain of 24 percent for bovine colostrum points at an earlier closure of the intestinal wall for the species-specific proteins. There was no further increase of Ig permeation after 12 hourly feedings. Growth performances and losses were identical in all groups.
