Estrotect Heat Detectors+

As good as a bull™

Estrotect Heat Detectors are an economic, easy-to-use and highly effective heat detection aid. Over 35 million Estrotect  Heat Detectors have been used worldwide, they are supported by university research and have been in the marketplace for over a decade.

You can purchase estrotect heat detectors from your local farm supplies store or visit our Heat Detection section on the online store.

Why Estrotect?

Estrotect Heat Detectors only need to be applied once per Cycle.  Alternative tail paints and paint sticks must be applied or touched up daily.

Detect Advancing Heat.  Other detectors are activated by one mount, sometimes as little as 3 seconds. Estrotect Heat Detectors minimize “false positives” due to a product design that rubs off over time.

 

 

How to apply Estrotect Heat Detectors

1. Keep Heat Detectors Warm

Estrotect Heat Detectors should be warmed to 38ºC immediately prior to application to activate adhesive. They should be soft and flexible at application for optimal adhesion.

Small quantities (less than 5 heat detectors) may be warmed inside clothing. For large quantities, put the detectors in a small esky with a hot water bottle or other heat source, as this is more effective and consistent.

2. Choose site of application

Ideal location for placement on the cow is halfway between the hip and tail head, evenly spaced perpendicular to the spine. Note:  Protect detectors from tail flicking by placing them near the top of the tail when fly counts are high. 

3. Brush hair thoroughly

Vigorously brush with the grain of the coat across the backbone on the back half of the cow to remove dirt, dust and shedding hair.

Do NOT brush hair with a steel bristle comb. Do not use stiff curry combs for brushing or cleaning.

4. Clean the hair

Clean the surface area with a cloth to remove any remaining dirt, dust, sand or sawdust. A painter tack cloth is suitable for the task.

5. Apply heat detector

Place heat detector on the application site halfway between the hip and tail head. Press down firmly and rub into hair with bare fingers. Do not apply in rainy weather conditions.

6. Check for results

As mounting activity occurs, the silver rub-off coating of the Estrotect will be removed, exposing its indicator colour to signal true standing heat. Approximately 50% of the silver rub-off coating removed indicates standing heat.

When the Estrotect is activated by mounting activity, the indicator colour appears very shiny and polished. The indicator colour may be less prevalent in high stress environments, hot weather, and high production or in crowded conditions as cows may be less inclined to mount.

 

DO NOT use Estrotect Heat Detectors with alcohol or oil-based pour-ons or sprays as they will damage the product. Doing so will void the warranty.
