Anti-BCV antibody levels measured over time in calves treated for BRD. Anti-BCV antibody levels were measured by ELISA in 39 calves from Herd 2 that were involved in mass treatment for BRD on August 12, 2016 (MT-2). Differences in mean antibody abundance were determined based on contrasts of least-squares means being different from zero in models with sampling time as a fixed effect. Sample collection times with the same superscript are not significantly different (Pā€‰>ā€‰0.05) in these contrasts
