General Use Hints

Code your tags with the cow’s
I.D. number. Should the tag
become scrubbed off during
an aggressive mount you
will know which one to watch
for “heat” activity.

This helpful hint sounds simple but it is important— Make sure the arrow points forward.

After breeding apply a second detector to help determine if she re-cycles. A second Kamar Heatmount Detector can be a good, inexpensive indicator to help determine if she is bred as well as check for repeat breeding. If the original detector is still firmly attached simply cut off the plastic bubble and apply a new detector on top of the old patch. (QuickStick Kamar Detector users will need to remove the old detector.)

Detector placement is critical to the product success. A gauge based on animal weight is supplied with each box of detectors. Use this gauge to determine approximate placement. Common sense should rule as to final placement. Always position the detector so it will receive maximum pressure from the brisket of a mounting animal. Size of the mounted animal versus the mounting animal will influence this final position. Keep in mind that Kamar Heatmount Detectors are an aid in identifying estrus in cattle. Common sense and appropriate visual observation are still necessary for a successful A.I. program.
