Synchronization programs offer an excellent opportunity to take much of the guesswork out of a reproductive program. But their adoption doesn’t mean you should stop heat detection on your dairy, cautions Roy Ax, University of Arizona extension dairy specialist. It is still an important component of reproductive management, Ax told producers attending reproductive seminars sponsored by the Professional Dairy Producers of Wisconsin recently.

Ax says there are several reasons to detect heats. They include:

  • Heat detection helps to confirm early post-partum cycling.
  • It is a good foundation for qualifying synchronized cows for re-breeding.
