An Application for Any Breeding Program
Over the past decade, ESTROTECT™ Heat Detectors have established a strong reputation in helping producers determine when their cows are at the maximum opportunity for artificial insemination pregnancy success. However, you may not know ESTROTECT™ Heat Detectors are more than just an AI tool. The core principles behind ESTROTECT™ Heat Detectors can also be applied to other areas of your breeding program, including:
Confirming Heifer Cycling
Apply ESTROTECT™ Heat Detectors to your cows/heifers for 18-to-26 days – the typical length of a cow’s estrus cycle.
- If the ESTROTECT™ Heat Detector has not been activated over this time, there is a high likelihood the heifer has not started having normal estrus cycles. This can be confirmed with another test, such as ultrasound or reproductive tract scoring.
- If the ESTROTECT™ Heat Detector shows at least 50% of the fluorescent signal layer over this time, the heifer is likely to be having a normal estrus cycle and will likely have a better chance to conceive.
After your AI breeding program or after bulls are removed from the herd, apply ESTROTECT™ Heat Detectors to your cows and monitor daily over an 18-to-26 day period.
- If the ESTROTECT™ Heat Detector has not been activated, there’s a high likelihood the cow is pregnant and should be confirmed with another test like ultrasound or rectal palpation.
- If the ESTROTECT™ Heat Detector shows at least 50% of the fluorescent signal layer over this time, the cow has been mounted multiple times and is likely to be in estrus – not pregnant.
