Abstract

Bovine respiratory disease (BRD) is common following weaning and movement of calves from individual to group housing. The objective for this preliminary analysis was to evaluate the effect of BRD in the 60 days following grouping on the survival, dystocia rates, and age at first calving for replacement heifers.
