HYPP

Does anyone know if there is a way to find out if a registered APHA horse has been tested for HYPP and the results? I’m not an APHA member

Call them - but they will only know if the horse was tested through UC Davis.

I just send in a tail sample to UC Davis and got my result a week later. Granted horse wasn’t papered (if he was, it wasn’t disclosed)

If a horse is positive, do they list in on papers? Now I’m curious.

You could try looking it up on AllBreedPedigree.com. There are millions of horses there, and a few breeds have been downloaded from the association’s records. I put my APHA gelding in a long time ago before HYPP testing was common. I was able to connect the pedigree on his papers and a 12-generation pedigree I had purchased from a woman on eBay. HYPP showed up in his sire’s profile several years ago as N/H.

That database can be fun to explore. Reports include line breeding, siblings, progeny etc… They have a photo function that puts together all of the available photos in one report. I ran a tail-male (all sires on top) which goes straight to the Darley Arabian. Can’t do the female because that line runs out, but I did see Man of War go by. :smiley: You have to join to get some of the reports, but you can get 4 months of access for $20.

If tested through the association, yes - it is listed on papers. At least for AQHA.

AQHA it’s on their papers. H/H cannot be registered.

APHA it’s not on their papers and only required for stallions whose offspring are intended to be registered.

Well I guess her sire is tested H/H. She is tested N/H so I got my answer. From what I have read, with a special diet N/H can be fully functioning horses?

Can be, I’ve heard.
My APHA filly, tested N/H, died at 5 from an attack.
But some live full lives.

AQHA H/H foaled after 2007 are ineligible for AQHA registration. I do not believe any other registry has a ban on them.

Like @mmeqcenter said, the important words in your sentence are CAN BE. Which means things can also go very wrong. Great one minute, not great the next.

Take a look at All Breed Pedigree website. There are millions of horses listed, and some breed registries have loaded data, including the Jockey Club and AQHA at some point.

I bought a 1994 APHA gelding in 2001. I had a 12 generation pedigree done at the time. I entered him using that information and was able to connect up to the historical data. You can get quite a bit of information just poking around, but for $20 for four months there are additional reports available which include line breeding, genetic influence, siblings, progeny, etc. There is a photo report that prints out everything available in the pedigree. Very cool for us Paint owners.

APHA points for his sire were there. A few years ago the HYPP status was added, which was N/H. I have no idea what the source was. His sire had died several years earlier. Impressive appears once in the pedigree.

My handsome sabino Paint is built like a TB. I ran the tail-male and he goes straight back to the Darley Arabian. The tail-female ran into a dead end. I did see Man o’ War in there some where. :smiley:”‹

Edited to add: Very weird. First response above said it failed, so this is #2.

Wow, really? When did that happen? All breed in particular has always been rife with errors because it’s always been a user maintained database. Pedigree query started off on the Del Mar site, and everything that ran at Del Mar was automatically entered, but it was also open for people to edit. All breed was created in part to keep the non tbs off of PQ, but since the only verified data on it is really that old Del Mar database, it’s kinda like the wild west. I find incorrect or incomplete stuff on there allllllll the time :lol:

Where did you hear about any relationship with the AQHA or JC? I’d love to read about that. Surprised, since the JC has their own open database in Equineline! Really too bad AQHA doesn’t follow suit, but they probably make some $$ in their lookups?

My grade horse I had tested n/h. I didn’t know HYPP was a thing. Horse was not sound in the mind, at alllll. Horse tried to attack other horses, managed to kick me, bite me. List goes on. When that test came back he was PTS. That was my first and last rescue horse 🤷🏼”â™€ï¸

I’ve heard that about many N/H and H/H, very sorry for your experience.
My little girl was an absolute doll, so easy to start under saddle (I got her as a yearling) and super reliable and easy.

Someone on another forum told me about it around 2002. There had to be downloads because there is no way all the TB or QH could have been manually entered; they include year of foaling and breed. The woman who did the 12 generation pedigree used stud books. I added several horses using that pedigree which is how I found the Darley Arabian. QH and Paints tend to have a lot of dead ends, for example “George Smith’s bay mare” bred to a specific named foundation QH sire who has TB.

It has definitely been user maintained which is why I had to add my Paint. Everything was free back then. When you add a horse you can put additional information in the comments screen and it can be edited. Back then the APHA registry had tobiano and overo, but “overo” was anything that wasn’t tobiano. I think these days APHA identifies “sabino overo” or “splash white overo”. Those 2 patterns have distinctive genes. I added “sorrel sabino” to the comments. I haven’t tried to enter a photo link yet.

I agree that there probably are a lot of errors because you can enter a horse yourself and enter or edit comments. There is no way Man o’ War or Darley could be there unless they came from a data download. The source of HYPP status is a mystery to me but it is a relatively recent addition to AQHA and APHA registration rules.

I love Deb Bennet’s long running articles in Equus magazine on the development of various breeds. Over time you can see where TB was added to breeding pools such as the QH. It takes patience and persistence to explore All Breed but you can track down some of the famous ancestors. I get a kick out of telling people I own a descendant of Man o’ War. They are very impressed, :wink:

Oh, yeah, no. That long ago? Unless it’s recent, there’s been no registery involvement. Yeah, individuals have actually added all that. “George Smith’s Bay mare” isn’t a dead end, that’s how they appear in the stud books.

I had an N/H QH gelding. I was able to keep him from having symptoms with simple diet changes. From what I read it is easier to keep a N/H symptom free than a H/H but I don’t know if that is urban legend or fact.

Who is breeding H/H horses?

I have no idea, but the sire is H/H! My friend was considering this mare. However, she has some behavioral issues under saddle, and has been tested N/H, and with that information combined, I have suggested to her that she pass on the mare. She doesn’t need to buy a headache. Our horses give us enough headaches without taking issues like this on intentionally. I hope she takes my advice.
