Fertility Report by Bull

Maintaining effective and efficient insemination procedures is crucial to achieving optimal fertility outcomes. Tracking which bulls are associated to the highest (or lowest) conception rates is integral for making practical decisions.

The Fertility Report by Bull displays the number of normal inseminations* per bull, and also their conceptions rates. Use this information to evaluate bull performance and accurately determine which bulls to use (and which to discard).

*Note: Normal insemination refers to an insemination followed up with one of the following events within 60 days:

  • Another insemination

  • Heat event

  • PD+ or PD- event

  • Not for insemination
