Relationship between anti-BCV antibody abundance and respiratory virus shedding. Anti-BCV antibody abundances from Fig. 5a were re-plotted to compare anti-BCV antibody abundance between calves that shed BCV at some point during the pre-weaning period (n = 2, 48, and 2 for Herds 1, 2, and 3, respectively) to those animals where BCV shedding was never detected (n = 58, 12, and 58 for Herds 1, 2, and 3, respectively). a initial vaccination, b preconditioning, c weaning. Differences in mean antibody abundances were evaluated by testing location, BCV shedding status, and their interaction, and no significant difference was observed within herds at any production stage (P > 0.05)
