Breed with Precision
The redesigned ESTROTECT™ Breeding Indicator features patent-pending Breeding Bullseye™ technology that demonstrates estrus intensity, indicates when cows are ready to breed, helps confirm pregnancies and provides pinpoint timing for AI protocols!

The precision-designed Breeding Bullseye™ takes all of the guesswork out of your breeding program. Simply, when the Breeding Bullseye™ – or the equivalent amount – is rubbed off, it’s time to breed!

Reading ESTROTECT™ Breeding Indicators
Like never before, producers and reproduction specialists can use ESTROTECT™ in a number of advanced breeding management applications to improve the quality and efficiency of their reproduction programs. ESTROTECT™ Breeding Indicators have been proven in university studies around the world.

Those Applications Include

  • Heat detection
  • Confirming pregnancies
  • Artificial insemination
    • Identifying optimal timing to execute insemination during timed AI protocols
    • Determining standing heat for standard AI breeding
  • Determining cycling in cows and heifers prior to breeding
  • Natural service to determine cyclicity or pregnancy after breeding
  • Synchronization protocols
    • Quality control indicator for breeding specialists
    • Pinpoint timing for executing breeding

If applied correctly, the silver and black surface ink will gradually reveal the indicator color as mounting activity occurs, indicating standing heat. Once the Breeding Bullseye™ or the equivalent surface area is rubbed off (50% or more), the breeding protocol should be initiated.

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.
