Our Breeding Indicators are more than just cattle heat detection patches. They identify all the main breeding considerations, making it easy for you to determine optimal estrus intensity, monitor cycles, indicates pregnancies and evaluate embryonic loss.

Identify When Cattle are in Optimal Estrus

When the Breeding Indicator is more than 50% rubbed off, it means the cow is in optimal estrus intensity and it’s time to breed. Research has proven that cattle express higher estrus intensity, and therefore, confirmed pregnancies are three times more likely when the patch is more than 50% rubbed off.1

Monitor Estrus at a Glance

The fluorescent colors of the Breeding Indicators make it easy to pinpoint where each animal is in their cycle — allowing for optimal estrus detection in cattle without someone being present when the mounting activity occurs.

Indicate Pregnancy

Breeding Indicators offer a simple and accurate method of pregnancy detection in cattle. If the patches show no signs of estrus activity following breeding, the cows or heifers can be assumed pregnant.

Identify Embryonic Loss

ESTROTECT™ Breeding Indicators can help identify embryonic loss by placing a patch on a cow or heifer after they have been confirmed pregnant. If the Breeding Indicator shows any signs of activity, it indicates she went back into heat and is no longer pregnant.


Easy as 1-2-3-4-5

With just five simple application steps, adhering the Breeding Indicator to your cattle is a breeze. To ensure optimal results, it’s important to follow each step carefully. We provide detailed instructions in video, web and printable formats to guide you through the process.

We exclusively use the Estrotect Breeding Indicators, and the breeding bullseye eliminates the guesswork. We exclusively use AI on our farm for a Fall calving season. We couldn’t be successful without the use of the Estrotect Breeding Indicators.

Estrotect allows us to be timely and precise on our breeding program! I really like the simplicity of just the color change of the patch telling me that it’s time to breed. Then we can change colors and calculate our average of first-service conceptions. This product is here to stay in my management toolbox!

Pink is best

We like the pink color best. It’s brightest.

They work well. We actually use spray glue to ensure they stay on.

I synchronize and time breed, but I also stick an estrotect patch on when we pull CIDRs. This has definitely increased conception rates as now I’m catching the early and late estrus cows and getting them bred on time.
