Semen & Supplies > Estrotect Heat Patches
ESTROTECT Heat Detectors are an excellent aid to the herdsman’s visual observation program for detecting cows in standing heat. The patches are applied to the tailhead prior to standing heat. When the cow is mounted during standing heat, the silver scratch-off surface of the patch is rubbed off to expose a fuchsia signal layer underneath. Patches are self-sticking, easy to apply and very accurate. Patches come in a pack of 50 but can also be purchased individually.
