A.I.TAGS (ORIGINAL)Rub-off Heat Detectors **Rub-off detectors DO NOT work with the **Smart AI System**

Product Details and Benefits

A.I.TAGS™ Rub-off tags are an excellent aid for dairy and beef producers in detecting cows in “mounting-heat”. Apply the detectors to your cows prior to “coming into heat” when synchronizing estrus cycles or after breeding and embryo transplant to check for return heat.

The detectors have a dark-gray, ‘Rub-Off’ surface and a bright colored signal layer underneath (in red, fuchsia, green, or yellow). This bright color begins to show through the gray layer after the first mounting resulting from the rubbing pressure. Additional mountings result in increased color exposure. If the tags are applied and timely observed, there is zero chance of a false reading! In addition, A.I.TAGS will also show an indicator that the animal may be going out of heat! Repeated mountings over time will cause the tag’s color signal layer to turn white. If you notice the tag turning white, you may have missed the heat.

Rub-Off vs. Scratch-Off

A.I.TAGS require pressure from mounting activity to allow the surface of the tags to “Rub-Off” and display the signal color underneath. If the tag you are using can be easily scratched off with your thumb nail; you are experiencing too many false positive readings, for example, from tail swatting or rubbing against branches or fences. Switch to A.I.TAGS and prove the accuracy of our product to yourself! Some tags call their surface “Rub-Off” but only true A.I.TAGS products deliver on that promise.



Prior to application, keep tags at body temperature.


Briskly brush top hair, remove dust, dirt, and loose hair.


Use clean dry cotton glove or cloth to remove remaining particles prior to application.


Apply tags in front of the tailhead but behind the hip bones. Place tag in a position that it is out of reach of the tail. Press firmly and hold down for 4 to 5 seconds.

Application Tips: For optimum adhesion we strongly suggest using 3M Super 77 spray adhesive (or a similar product) as a final application prep. Do not apply adhesive to the tag! Only apply adhesive to application area on animal, allow to dry 4-5 seconds and place tag on animal holding tag down firmly for 2-3 seconds. When doing this, users of our tags report a retention rate of 96%. Just a short spray will help insure a successful heat detection every time on every animal.

Ideal placement of A.I.TAGS is between the hip bones and tailhead area. Protect A.I.TAGS from tail swatting with increased fly populations. Place the tag where the tail cannot reach it, closer to the tailhead. This will also eliminate the ends of the tags from lifting because of tail rubs.

A.I.TAGS Protocol

A.I.TAGS™ are applied to dairy and beef cows prior to “coming into heat” to detect “mounting-heat.” By following simple instructions, A.I.TAGS will provide optimum heat detection resulting in more pregnancies, which greatly improves your “bottom-line” profitability! Whether used for AI, embryo transplant or natural breeding purposes, knowing your cows are in heat is important!

* Only trim hair during molting conditions or when hair is very long. Be careful not to trim hair short. Tags will not stay on animal if adhesive comes in contact with the animals natural oils on shorter hair.


Where can I buy A.I.TAGS?

A.I.TAGS are available in the USA here, and in many countries around the world. Contact us to find out where they can be purchased in your country.

Do A.I.TAGS work in cold weather regions/conditions?

YES. You must keep tags warm just prior to application. We recommend using hand warmers found at hunting goods stores. One hand warmer placed inside the retail sleeve will keep tags at the optimum temperature for proper application

Can I use A.I.TAGS during animal molting season?

YES. Always use a rubber brush and brush briskly to remove loose hair. Long hair will need to be trimmed shorter but do not trim too short or you will get into the natural oils on the animals hyde. We highly recommend using a tack cloth after brushing to remove any remaining dust, dirt or loose hair. Tack cloths are available on this website.

Will A.I.TAGS show false positives during fly season?

YES, if you apply them in the wrong location you will see the tail causing the ends of the tags to lift and showing marks on the tags. them We recommend moving them further to the rear during heavy fly concentrations. Apply 1 to 3 inches in front of the tailhead. Be sure to avoid getting fly spray directly on tags. Fly spray will cause damage to the rub off surface.

Will A.I.TAGS fall off?

NO. If animal is properly cleaned, tags are warmed in cold weather and tag is properly placed on the animal, A.I.TAGS will not fall off. As stated before, longer hair must be trimmed.

Where do I apply A.I.TAGS?

Half way between the hip bones and the tail head is a good place to start. You will learn the best application area on each cow as you use them.

How do I clean the animal before applying A.I.TAGS?

Use a rubber brush to remove dust, dirt and loose hair. Use a tack cloth to wipe area clean prior to application.

Are A.I.TAGS available in other colors?

A.I.TAGS are available in four colors. Red, Fuchsia, Green & Yellow.

How do I use the other color tags with my herd?

Use 1st color for first service to detect heat, use 2nd color for next service to check for return heats, use 3rd color for synchronization, use 4th color for problematic cows for vet check.

How do I read the A.I.TAGS?

Refer to images found on the package. A.I.TAGS will show a two color change as the animal is being mounted.

What do you mean by “Rub-Off” Heat Detection?

Unlike “scratch off” tags. A true “Rub-Off” tag will not “scratch off”. The only true “Rub-Off” tag found anywhere in the world is A.I.TAGS. If you can “scratch off” the top surface of the tag you have with your thumb nail or a quarter, you do not have a “Rub-Off” tag.

How are these tags different from other “Scratch-Off” tags I’ve seen or used in the past?

Everything will leave marks on a “scratch off” tag. It is very hard to identify if they are showing mounting activity or if they are showing marks from a tree, brush, tail, head rubs etc… ONLY true mounting activity will “Rub-Off” the top surface of A.I.TAGS.

Do I use glue adhesives with A.I.TAGS?

NO it is not required if applied properly. Be sure to follow warming and cleaning instructions above.

What type of brush and wipe should I use to clean the animal?

Always use a rubber brush as shown in the images and a tack cloth, both easily found online or in local stores.

Why is it important not to trim the animal hair too short during molting season before applying A.I.TAGS?

If hair is trimmed closely to hyde, lanlin will be present on the animal’s hyde. Adhesives will not adhere to lanolin.

How long does it take to apply A.I.TAGS per animal?

Cleaning and applying A.I.TAGS will take less than a minute if using a rubber brush and tack cloth.

How often do I apply tags?

Apply 1st detector just prior to oncoming heat cycle or when hormones are injection. Apply a 2nd detector after artificial insemination to detect for reheats.

What does the “Two Color Change” mean?

A.I.TAGS will have a first color change to show initial mounting activity. As animal is showing a more intense heat cycle she will be mounted more aggressively. After many mountings or extremely aggressive mountings, A.I.TAGS will begin to show a white color. As you learn to read the two color change, you will know exactly where your animals are in their heat cycle. Read it like an x-ray. A.I.TAGS show exactly what has been happening when you are not watching.

What does excessive white indicate on the tags?

A mostly white tag could be an indicator that you have missed the heat cycle. Or that you may need to service very soon. You will learn how to use the tags.

What causes the ends of the tags to lift?

If you see the ends of A.I.TAGS lifting and you have applied them properly it is because you have applied them in the area that the tail can reach. To prevent lifting, apply the tags closer to the tailhead out of the tail fly swatting area. Especially in fly season or with loose stools when cows are eating grass.

Do you have a Smart Technology option for A.I.TAGS that will work with an optical scanner?

YES. Coming in 2018 you will not have to look any longer. Our cameras and SMT system will be automatic heat detection and automatic sorting. Finally! A.I.TAGS SMT will be the best heat detection system in the World!

Where is A.I.TAGS available globally?

A.I.TAGS are already found in many countries around the world and the list is growing daily! Drop us a note, we'll find them for you.

We use rotary brushes on our farm, will they mark the tags?

Yes, rotary brushes will mark A.I.TAGS. Turn rotary brushes off during heat detection periods.
