Heat Detection Tags

Industry Leading AI Tags With Rub-Off Heat Detection

Developed in the USA as the World's only true Rub-Off heat detection system, A.I.TAGS™ give dairy and beef producers confidence knowing when their cows are in heat.

AI Tags for Dairy & Beef Cattle

How They Work

Unlike traditional scratch off tags that are susceptible to false positive readings, ​AI Tags will indicate when a cow is in 'mounting-heat', giving the producer adequate time to prepare for artificial insemination.

The detectors have a dark-grey, ‘Rub-Off’ surface and a bright coloured signal layer underneath. This bright colour begins to show through the grey layer after the first mounting resulting from the rubbing pressure. Additional mountings result in increased colour exposure. If the tags are applied and timely observed, there is zero chance of a false reading!

Optimum heat detection results in more pregnancies, which greatly improves your profitability! Whether used for AI, embryo transplant or natural breeding purposes, knowing when your cows are in heat is important!

Reliable & Friendly Service You Can Count On

"We would like to claim credit for all of this but the fact is that the improvement in our herd is down to the females we started with and bull selection, which is mostly the work of Peter Midson of Eastern Artificial Breeders.

The assistance of Pete cannot be overstated, so thanks Pete for your help and easy, friendly attitude in helping Kogo Angus come of age."
