Get Penn State’s dairy reproduction drill-down tool The Penn State Reproduction Drill-Down Tool provides a systematic approach to critically analyze the major factors affecting heat detection rate and conception rate so that problem areas can be highlighted and discussed.

The drill-down tool asks a series of “trigger questions” that indicate whether conception rate, heat detection rate or both are the greatest contributors to low pregnancy rates. Answers to the drill-down questions highlight areas requiring attention to improve performance.

Drill-down questions are divided into two general categories — factors affecting heat detection rate and factors related to conception rate  — and then are broken down into more specific categories: ineffective heat detection, anestrous cows, confinement and footing, heat stress, estrous synchronization program, inaccurate heat detection, artificial insemination technique, ration or feeding management issues, reproductive health, and environmental issues.
