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.

Had a fella call me up once to AI his cows! Told me his entire herd was Blaze orange! Come to find out the girls found a new scratching spot on a tree that had fallen over! Still recommend your product to all my customers!

Much better than the old spray paint method

Estrotect patches have worked great for us. We do find that they stick a bit better if we do a quick spray of 3M spray adhesive and then hold the sticker down for a few seconds. They are much easier to read then when we sprayed their backs and hips with spray paint!

That extra visual to judge whether a cow has been in heat, especially when I didn’t see her in heat. Like that extra help, to decide when to breed.
