Mounting Evidence

The ESTROTECT heat detection system is an excellent aid to any operation's program for detecting cows in standing heat. Apply the self-adhesive ESTROTECT heat detection patch to cows prior to standing heat or when cows are given synchronization injections. No glue is needed if applied correctly.

Each patch has a silver scratch-off surface. After the animal is mounted, the bright signal layer underneath is shown for easy observation and reading. Additional mountings result in increasing color exposure. This picture shows the difference between the scratch-off patch with more mounting signaling the maximum opportunity for breeding. Other detectors are activated by one mount, sometimes as little as three seconds. ESTROTECT Heat Detectors minimize “false positives” due to a product design that rubs off over time.

The patches come in five fluorescent colors - yellow, red/orange, green, blue and fuchsia (pink).

Application Procedures

  • Warm ESTROTECT to human-body temperature before application. (As long as the product is kept warm, it can be applied in all seasons.)
  • Remove dirt, sand, dust, shedding and loose hair (do not shave hair) from the tail head with a leather glove or painters tack cloth (do not use a curry comb)
  • Wipe away any excess moisture with a towel
  • Press ESTROTECT onto the hair across the backbone (side to side) just forward of half the length between the hooks and pins. Vigorously rub ESTROTECT onto the hair with your bare fingers. Rubbing will not damage the silver surface.

Heat Detection Economics.
Failing to detect heat and/or incorrect detection of estrus can result in significant economic losses. Missing a heat cycle may cost anywhere from $42-to-$126 for an individual cow*. At approximately $1.30 per ESTROTECT Heat Detector patch, the economics show the value of a heat detection aid that works.

*Based on the average cost of a day open for beef cattle ($2 per day) and dairy cows ($6 per day).
