Thoroughbred Recording

How to get your Jockey Club-registered Thoroughbred listed for breeding with AQHA.
American Quarter Horses are extremely versatile horses, very strong and powerful. There’s no question about the American Quarter Horse’s ability to beat out any other breed in a short-distance race – he’s just built for it! But quite some time ago, AQHA’s eyes turned to the Jockey Club and the large, long and lean Thoroughbred horses it registers. Thoroughbred (TB) horses succeed in long-distance racing. So what happens when you mix the sought-after characteristics of the Quarter Horse and the Thoroughbred? You get an Appendix Quarter Horse that will be a powerhouse on the race track and capable of so much more!
Now that I have your ears (well, I guess eyes…), I will let you know how to go about getting yourself one of these Appendix Quarter Horses.
Above all else, AQHA must maintain the integrity of the American Quarter Horse breed. So you have to get a Thoroughbred horse approved before you can breed it to an American Quarter Horse. Simply submit the following information:
- A front and back photo copy of the Jockey Club certificate showing that you are the owner.
- Four, clear-view color photographs of your TB. (Bit of trivia: The photos are still required to verify the existence and amount of white markings the horse has. The only change is that AQHA will still take the horse if the white markings are excessive. Before, this was definitely a deal-breaker.)
- A $50 recording fee. ($90 if the owner is not an AQHA member.)
- A signed statement authorizing AQHA to obtain DNA information (if any) from the Jockey Club. If the DNA type cannot be recorded with AQHA or if the horse does not have DNA on file, a $50 DNA testing fee will need to be submitted and the horse tested before we will approve the horse for breeding.
The horse will be assigned what is called a T-number (ex: T0000000). This serves as the TB’s AQHA registration number. A letter is mailed out with this information when the recording is complete. Buyer beware, though! A T-number does not always indicate that a TB has been approved for breeding with AQHA. For example, if the DNA process was never completed, the horse can still be assigned a T-number, but it is not yet approved if we do not have DNA. Another bit of TB trivia: AQHA places the year the TB was born at the end of the name. This policy came from the days when names were not eligible to be reused and could not be spelled the same as any other name. Our database requires these additional numbers so the TB names can be added.
If you purchased a Thoroughbred and wonder whether it has been recorded with AQHA, contact us and we’ll look the horse up for you. If the horse does have a T-number, simply submit a copy of the Jockey Club certificate and a $15 transfer fee ($55 if you are not an AQHA member), and AQHA will update the record.
Registering an Appendix
So how does AQHA register half Quarter Horse-half TB offspring? We’ve created the Appendix Registry. An Appendix Quarter Horse is not limited in any area except for breeding. Appendix horses are only eligible to breed permanent-numbered Quarter Horses. Appendix horses are denoted by an “X” at the beginning of their numbers (Ex: X0000000). So, you cannot breed an “X” with a “T” or an “X” with an “X.”
Appendix horses can advance and become permanent-numbered Quarter Horses. The basic requirement for advancement is a Register of Merit in showing (open division) or racing.

Dear Ms. Randall,
I work on a Thouroghbred breeding farm and we bred a quarter horse mare to one of our stallions this year. What do I need to do as farm as providing the breeding records so the foal can be a registered appendix?
Thank You,

My TB broodmare is already DNA certified by the Jockey Club. Now I must pay you $50. to record it? Is that correct? A bit excessive is
isn’t it?
Do you have a form or a sample of the letter I need to request that info from the Jockey Club?
The AQHA is going downhill :0(

DO YOU THINK I CAN GET A MARE APPENDIX PAPERED IF SHE HAS TB ON BLOODLINES OR DO YOU HAVE TO BUILD DNA.. SHE IS A CROP OUT AND DIDNT GET THE AQHA PAPERS BEFORE AQHA STOPPED ALLOWING IT..NOW THE RULE HAS CHANGE AND I CANT BUILD ANY DNA ON HER BECAUSE ALL PARENT S ARE DEAD.. AND NONE OF THIS MARES OFFSPRING CAN BE PAPERED BECAUSE SHE IS THE MISSING LINK IN CHAIN…SHE HAD QUARTER PARENTS JUST CAN;T PROVE IT BECAUSE THEY ARE ALL DEAD.. I JUST WANT TO GET MY GELDING OUT OF THIS MARE REGISTERD EVEN IF ITS APPENDIX BECAUSE THEN COULD SHOW AQHA…

Im so glad I stumbled on to your site!!! My question is this… I have a TB mare, a vet breed her to an AQHA stud, baby is 2 this yr and not registered? I want to put the baby on the track next yr. Do I follow the same rules as above even if he’s already here and lovable? The TB mare is currently at the track with a trainer so I assume there is DNA already at the Jockey Club?! Thanks for being there and any info would help me out! Pat Johnson

Dear Ms. Randall,
I’m french so excuses my english…
My mare LAYDUR ( TB) is breeding of a QH (sw king champagne). She race but I do not find her name on the site of the jockey club. Those this said to me that she had to be registered in France Galop because we are in France.
Is it the good information? Could I declare the foal to the aqha in the same way?
On the other hand, his tests DNA are made, do I have to ask their transfer or is it automatic ?
Here is! I worry maybe about nothing but I like that things are clear from the beginning and that I can bring all the documents at the right time.
Thank you in advance for your diligence.
Good day and happy new year !

I have an unregistered Aglo/TB mare that I want to breed. Is there any way to get the foal AQHA registered?
I only know her sire raced (TB) and her dam was an anglo/TB cross…no idea if she was registered at all.
I’m prepared to get DNA and whatever it takes…she’s a lovely mare that’s only retired due to a paddock injury.
Thanks
