ESTROTECT™ Breeding Indicators are the only product of their kind proven by leading researchers. We developed and tested the ESTROTECT™ Breeding Indicator on thousands of cows around the world. According to a 2018 third-party, timed-AI beef cattle trial, when the ESTROTECT™ Breeding Bullseye™ is rubbed off by mounting activity, cows are up to THREE TIMES more likely to result in confirmed pregnancies than if estrus is not detected prior to insemination.
As Good As A Bull™
ESTROTECT™ Breeding Indicators help producers identify their animals for the maximum opportunity for pregnancy. Below are results from university-led studies.
1) ESTROTECT™ Breeding Indicators help confirm pregnancies in a 2014 fixed-timed AI trial.
In the hot and humid 2013-2014 breeding season in Brazil, the University of Missouri used ESTROTECT™ Breeding Indicators to determine estrus activity in approximately 1000 Nelore females (Bosindicus breed). Patches were applied to cattle when CIDRs were removed from animals followed by fixed-time artificial insemination (FTAI) 48 hours later.
The results in Figure 1 indicated that cows with 50% or more of the ESTROTECT™ Breeding Indicator rub-off surface removed were significantly more likely to be pregnant after FTAI. Figure 2 provides a more comprehensive breakdown of this study.
2) ESTROTECT™ Breeding Indicators help confirm pregnancies in both AI and natural service operations.
This timed-AI beef cattle trial compared ESTROTECT™ Breeding Indicator’s success in confirming pregnancies to blood-based tests analyzed by three different labs. The results showed that ESTROTECT™ Breeding Indicators performed better than or equal to blood-based tests in confirming pregnancy.
3) ESTROTECT™ Breeding Indicators perform As Good As A Bull™ in determining standing heat.
This trial shows the ESTROTECT™ Breeding Indicator rub-off technology performed equally as good as a bull and vigorous visual observation (every 3 hours / 24 hours a day / 7 days a week) at determining standing heat.
