Two groups (A and B) of 6 piglets, weaned at 21 days (D0), received ad libitum the same diet during three weeks. The piglets of group A were not submitted to a colostrum supplementation while those of the group B received daily and orally 5 g of bovine colostrum. Each week, piglets were weighed and blood was taken on each one of them. One piglet of each group was sacrified on D0 and the rest of the animals on D21. Mesenteric lymph nodes (ML), iléal Peyer patches (iPP), jejunum and spleen biopsies were taken on each piglet before death. The haematological values and the intestinal histo-morphological data between the two groups were not significantly different, but FACS analyses on the lymphocytes in the biopsies and the determination of stimulation index suggested a significative effect of colostrum on the lymphocytes populations, with, in the ML, an increase of the LB population (14 % vs 28 %, P < 0,05) and, in the iPP, a reduction of the LB's (54,99 % vs 8,44 %, P < 0,01) with an increase of the LT cells (16,87 % vs 72,00 %, P < 0,001). An increase of the lymphocyte stimulation index from piglets receiving colostrum was observed the second day of in vitro stimulation with colostrum. In brief, the answer of the immunity system to bovine colostrum seems to be restricted to the intestinal immunity system and is characterised by an activation, a multiplication and a modification of the lymphocytes ratios.
