Abstract

A culling rate> 30% in dairy cattle is common in United States and Canada, despite general recommendations to lower cull rates in order to save on replacement costs. Also, higher cull rates are sometimes viewed as a sign of management failure, but the association between culling and disease at the cow level may not hold true at the herd level. Therefore, the objective of this study was to explore the relationship between disease events and individual-cow survival, and the relationship between herd-level disease incidence and culling rate.
