Kamar Heatmount Detectors are a valuable heat detection aid that assist in identifying cows ready for artificial breeding. The detectors are a pressure sensitive device with a built-in timing mechanism designed to be activated by standing heat behavior. Glued onto the sacrum (tail head), pressure from the brisket of a mounting animal requires approximately 3 seconds to turn the detector from white to red. This timing mechanism helps distinguish between true standing heat versus false mounting activity. Standing heat behavior in the bovine is the most reliable sign that a cow is ready to be bred.
