(A to D). Liver concentrations of Se (A), Cu (B), Zn (C) and Mn (D) for beef calves treated with injectable trace minerals (VAC + ITM) or not (VAC + SAL), 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 standard error of the mean (SEM). ¹ Hepatic trace mineral concentrations references values based on Herdt and Hoff, 2011. ^{x, y} Significant difference between groups (P < 0.01 for Se and Cu; and P < 0.05 for Zn).
