Bad Wind Heredity? True or False

[unclewiggly]

Just curious if anyone has proof positive that a stallion who developed a roaring problem during his career will pass it on.

This is a lovely individual a TB who is well breed has very correct conformation decent feet and big gaites...But he has a roar and surgery did not help, but didn't stop him from successfully racing either. Do not bother to re-direct me to other stllions thats not my question.

He is exceptonal enough in gait, mind conformation to warrant a serious look but the wind has become a bit of an issue and I really want to hear real time experiances.
I have heard other opinions over the course of years say yea and nay.
Do any of you have statistical proof or real life proof preferibly.
Feel free to express your opinions good or bad this is totally a fact finding question there is no offense to be taken or any smack down.
All will be appreciated.

Well, if the articles on TB Heritage are correct, roaring CAN be genetic.
Here is what I pulled up there with a search on roarer.

I'm not sure if there is enough conclusive evidence either way.

But another question might be, which sport would you be breeding for? This might be a significant issue for racing or eventing, but for a sport like dressage, I don't think I would pass up on breeding an otherwise nice horse because of roaring. It is my understanding the surgery is fairly advanced nowadays and not such a big deal, for those who opt to do it. (I've also been around plenty of big fancy warmbloods who were roarers who didn't have the surgery and were still successful dressage horses.)

I believe I once read about Brentina having roarer surgery, and she went pretty far ;) and is now being bred. Does anyone else know for certain if this is true?

Don't know if it's scientifically proven, but having been around many offspring of certain sires, it would seem it is true. To be honest, I wouldn't breed any of my mares if they had wind issues and that goes for any sport. While it may or may not affect them in their chosen sport, it's always going to be an issue when selling.

This stallions Roar is a mechanical problem cause after he had a botched surgery.

He had a Chondroma (chondroiton?) most likely from a throat infection. They took the thickened bit off the flap, took to much and he ended up w/ a partial paralysis.
He is lovely in every other way. Ankles bit rough to look @ but full flexion and sound.

The mare is lovely and fine.

But are you saying you would not breed a mare w/ a wind problem to a stallion w/ a roar issue. Or not breed a mare who roars period.
I am looking for the H/J ring and also dressage.

If that was caused by a surgical procedure, then it is most certainly NOT genetic and I can't imagine how it could be passed on. That's like saying that because you were in an auto accident and broke your arm that all your children would wind up with broken arms just because you had one.

According to TB Heritage, some of the greatest bloodlines in the breed descend from roarers, beginning with Pocahontas, who is in the pedigrees of almost, if not, 100% of TBs. Touchstone is another that they have identified as a roarer. Some developed roaring later in life, and some seem to have been born with it. According to them, Humphrey Clinker was a roarer, as was his son Melbourne, and Melbourne's great grandson, Barcaldine. That line is the source of Precipitation/Furioso and Man O'War. Line was also famous for really bad temperaments--on both sides of the pond..

I'm not sure, given that, that roarers should be disqualified from breeding if they have still been able to excel at their given discipline.

Roaring from a botched operation would seem to have nothing whatsoever to do with the possibility that descendants might roar.

Because roarers are often found in horses with a certain neck conformation, it may be considered that it can be passed on - even if not genetically a trait?

I have a sister of a roarer - there were five full siblings, quite similar in conformation and looks, (only one was the roarer), and she has not passed it on to her six to date descendants.

So, yes, I would probably breed to one if he had not produced any after a small test crop.

While there is no conclusive truth that it is genetic, I would think that everything is genetic to some degree because a foal is a result of the mating of two parents. That said, I'm not sure that it would keep me from breeding a fine mare or stallion unless they were consistently passing it on, since it has not been proven to be consistently passed. It would be more of a consideration for racing or upper level eventing than some other disciplines.
