Accurate heat detection is critical to the success of artificial insemination (AI). CRV Estrotect™ Heat Detectors provide the most accurate way to detect a cow on heat.
They are a 11cm x 4.5cm rectangular patch that sticks onto the cow’s rump. With each mount, the surface of the breeding patch will gradually turn from black to a bright colour alerting the farmer she is ready for insemination.
Use CRV Estrotect™ Heat Detectors to help teach farm staff to identify when a cow is on heat.
EASY TO USE AND ACCURATE!
- Only one patch per cycle is required compared with alternative tail paints and paint sticks, which must be applied or touched up regularly.
- While other detectors are activated by one mount (sometimes for as little as three seconds) CRV Estrotect™ Heat Detectors work gradually exposing the indicator colour, giving you more accurate results.
- With the new Breeding Patch it’s very simple to use. Once the patch is 50% rubbed it’s time to breed.
This graph from the University of Missouri showed that cows with 50% or more of the ESTROTECT Breeding Indicator rub-off surface removed were significantly more likely to be pregnant after artificial insemination.
APPLY IN 5 EASY STEPS
Heat activates the adhesive. Store at or above human body temperature (37ºC) when about to apply.
An ideal location for placement is between hip and tail head, perpendicular to the spine.
Brush with the grain of the hair to remove dirt, dust and shedding or moulting hair. It’s recommended to only use the ESTROTECT Rubber Brush.
Clean the area with an ESTROTECT Cleaning Cloth to completely remove any remaining dirt, dust or sand.
Place detector across spine of cow, press down firmly and rub into hair with bare fingers.
