Peripartum changes in antibody producing capability of lymphocytes from dairy cows.
B-lymphocyte populations and the in vitro antibody producing activity of lymphocytes were measured to evaluate the lymphocyte function of periparturient dairy cows. Changes in B-lymphocyte populations were not significantly different in cows during this period. Significantly decreased numbers of plaque-forming cells were observed in lymphocytes from cows at parturition and 3 days after parturition compared to those in lymphocytes obtained 14 days after parturition.
