Twenty-six Holstein bull calves born from primiparous and multiparous cows without dystocia were assigned to a randomized complete block design to one of two treatments within each block: colostrum with no supplemental sodium bicarbonate or colostrum with 30 g of supplemental sodium bicarbonate. Calves were fed colostrum from nine different batches with an immunoglobulin G (IgG) concentration of 82.05 +/- 8.45 g/L and the total amount of IgG fed of 329.89 +/- 34.56 g at 0 h and 6 h postpartum. Calves were fed 2 L of milk replacer (MR) at 24, 36, and 48 h postpartum. The addition of sodium bicarbonate had no affect on IgG absorption. Serum IgG concentrations at 0, 6, 12, 24, and 48 h postpartum were not different between calves supplemented with or without 30 g of sodium bicarbonate to colostrum. Area under the curve (AUC) for IgG was also not affected by the sodium bicarbonate treatment and apparent efficiency of absorption (AEA) was not improved by 30 g of supplemental sodium bicarbonate.
