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.

My "go to" for heat detecting

February 15th, 2022

We have used several different heat detectors, and have found Estrotect detectors the easiest to use.


Accurate with no mess!

February 10th, 2022

These detectors have been a game changer on our Dairy Farm. There’s no messy glue, just peel and stick, how much easier can it get. Our heat detection rate has climbed significantly since switching to estrotect, and I will never use anything else.
