HOW ESTROTECT™ WORKS
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.
Application
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.
REVIEWS
Stays put and works hard like you!
Estrotec patches stay on better than any other heat detection patch. There are some other patches that are cheaper but you get what you pay for and we can’t afford the lack of value with the other patches. The bullseye has taken the heat detection up a notch so we are even more confident when to breed. Estrotec also has some of the best support people in the business, Jerry and Boyd are as good as it gets!
Reliable
We’ve used estrotect for the last 19 years. Very reliable.
Great indicator of beat time to breed
My success rate is near 100% utilizing estrotect.
Great product.
A.I. Technician
I absolutely love Estrotects. Jerry Jones is a great guy to work with.
Easiest way to detect heat, don’t have to stand there for an hour!
We use these on our beef cattle that we are strictly AI-ing. I can easily use binoculars and see if anyone is in heat without having to trudge out to pasture twice a day. It’s very simple to see the difference between social/accidental mountings and scratch off and actual heat. Highly recommend! These helped me to get the majority of my cows settled via AI without the use of hormone and syncing protocols.
