Abstract

Herd size is frequently associated with differences in reproductive management strategies such as the use of fixed-time AI (TAI) and outcomes such as conception rate (CR), pregnancy risk (PR), and stillborn and abortion percentages. Although reproductive outcomes may also differ by geographic region, they may be used as benchmarks to assess reproductive management success within a dairy. In this study, reproductive outcomes were evaluated to determine overall CR, PR, stillborn, and abortion percentages and to establish benchmarks for the most effective 20% of operations.
