The association of recovery status1 with relative changes2 in lying time (a), total step count (b) and acceleration index (c) (LSM ± SEM) for the day of diagnosis (day 0) and the 10 days after antimicrobial intervention for Bovine Respiratory Disease for preweaned, pair-matched calves (n = 19 pairs) offered 10 L of milk replacer/day by an automated feeder. 1Bovine respiratory disease (BRD) status was defined as a clinical score of ≥ 526 lobar lung consolidations ≥ 3 cm2 and all calves were treated for BRD on day 0. Recovery status was defined as calves that either resolved symptoms of BRD within 10 days post-antimicrobial treatment (recovered) or had clinical BRD status from days 10–14 (relapsed). 2Relative changes were calculated with day of antimicrobial treatment as a baseline (100%); relative changes were generated by dividing each day after BRD diagnosis (day 1 to day 10) by the baseline (day 0). Significant differences by day are not reported.
