Least square means (LSM) and standard error of the mean (SEM) for total white blood cells (A), lymphocyte (B), granulocyte (C), monocyte (D) and platelet (E) counts of beef calves treated (VAC + ITM) or not (VAC + SAL) with injectable trace minerals (ITM) concurrently with MLV-BRD vaccination, or calves not vaccinated or treated (UNVAC). Calves received vaccination and treatment (ITM or saline) on study day -5, and were individually challenged with ncp BVDV2 (strain 890) five days later (day 0). Errors bars represent the SEM. ^{x, y, z} Significant difference between groups by each study day (P < 0.05).
