The role of colostral immunoglobulins for the protection of newborn calves has been studied extensively, but little is known about the importance of colostral leukocytes. To study the uptake of colostral leukocytes in the intestine of calves and to determine preferential sites for this uptake, FITC-labelled colostral cells derived from the respective dams were injected into intestinal loops with/without Peyer's patches of three male Holstein Frisian calves about 5h post natum. In adjacent loops, PBS was injected as control. Loops were excised after an exposure of 1.5-2h. FITC-labelled material and cells were detected by the direct immunoperoxidase method in paraplast sections. Twenty-five consecutive sections were evaluated from each localization. Uptake of labelled material and cells was observed in all three calves in the jejunal Peyer's patch and in two calves in the ileal Peyer's patch as well. In the jejunal Peyer's patch, labelled material and cells were present in epithelium, domes and sinuses around lymphoid follicles, whereas in the ileal Peyer's patch, they were found in the sinuses only. These findings confirm that uptake of colostral leukocytes through the intestinal barrier is possible and that the preferential route of uptake is through follicle-associated epithelium of Peyer's patches.
