Every great invention begins with an idea, and for ESTROTECT™, that idea came from an unexpected source. The story starts in Elmwood, Wisconsin, where a group of herdsmen were brainstorming ways to create an innovative heat detector for cattle. As the group grappled with the problem, someone made a suggestion that would change the course of the cattle breeding industry. “Let’s look at lottery tickets!”

From this unusual inspiration, the idea for ESTROTECT™ Breeding Indicators was born: a heat detection device with a rub away surface, showing farmers when cattle are in standing heat before their very eyes.

Our highly effective ESTROTECT™ Breeding Indicators make a valuable addition to any breeding program. Packing multiple uses, including cattle estrus detection, cycle monitoring, pregnancy indication and embryonic loss identification, our Breeding Indicators are proven to help increase confirmed pregnancy rates.

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.
