(A and B). Least square means (LSM) and standard error of the mean (SEM) for serum neutralizing antibody titers to BVDV-1 (A) and to BVDV-2 (B) for 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) at 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).
