Kaplan-Meier survival analysis of calving-to-pregnancy interval for cows that gained (open triangles), maintained (closed circles), or lost (open circles) BCS between calving and 21 d postpartum. Cows gaining BCS between calving and 21 d postpartum had a median calving-to-conception interval of 84 d, compared with 113 d for cow maintaining BCS and 128 d for cows losing BCS between calving and 21 d postpartum. The symbols on each line represent a censoring event (cow removed from analysis due to death, culling, or designation as “do not breed”).
