I am posting for a friend who has has produced 5 mares off of her appendix broodmare. These mares are the 3rd generation that she has owned so the background is known. The broodmare is 16.1 and had been bred to 3 different TB studs. The first 2 mares are 16 hands and healthy. The following 3 (2 different studs) have produced mares 17 hands and over even though the TB studs were both in 16 hand range. The older of the 3 had some semi club foot issues but that has resolved. The other two have had severe OCD and tendon and foot problems. One has had to be put down. The last filly has just been diagnosed with Wobblers as well as front leg structural abnormalities. Obviously this mare will not be used for breeding but does anyone have info. on likelihood of one of her sisters (healthy, no joint issues) passing on Wobblers Syndrome is she is bred. Vet feels that there is a genetic tendency for giganticism but is not sure of ramifications. |

While there is a known genetic factor for DOD's, it is worthwhile considering that they may also be caused by environmental factors (esp. overfeeding, or feeding of certain diets). This may result in DOD's where there is no hereditary aspect, or the turning on of a genetic switch where there is a factor - which may not be turned on (and therefore no DOD's) in other situations.
If it were me, I think I'd closely evaluate all factors more closely before coming to an absolute conclusion. |

I know this is old, but it has peaked my interest.
Are any of these problems actually genetic?
I was led to believe Wobblers was due to spinal trauma or malformation in one of the neck vertabae..(5th?)A nerve is trapped and hey presto! Wobbler! Is this true?
And all the research I've read on OCD's say it's about growth rates and feeding. So size would be the problem more than genes. I know that some mares don't throw anything small, so I understand how that connection is made.
These things interest me greatly, so any links to articles or information would make me a very happy girl!!! |

There is an excellent presentation available from the University of Kentucky on wobbler syndrome in the equine. Rather than repeat what they have to say, I'll just leave it at that!  |

Figured I'd just use this thread instead of starting a new one. My 2 1/2 y/o Friesian sporthorse gelding, Huck, has just been diagnosed with wobblers syndrome. He is also a roarer. Not sure if the 2 are connected or not at this point. Anyway I come to the genetics folder b/c I'm wondering if it would be advised to breed the same mare to the same stallion again. Huck did have what I believe was a traumatic injury last spring. He was cornered by another horse and forced over the fence. His rear legs were entangled and where he was lying his head/neck area was right next to a huge rock. I did not see the incident happen but he very well could've hit that rock. All of his problems started after that incident. It began with cross cantering and then he started having food come out his nose after he ate. Then the vet said well let's see if he'll grow out of it but it has gotten progressively worse and wobblers was just confirmed last week. It is at his cervical 4/5 junction. This was my dream horse and now his future is so very uncertain. Dreams of riding and showing are now gone and I hope for him to be able to live a long, happy life. Anyways any thoughts on re-breeding the mare are appreciated. This is Huck's website for anyone who's interested www.freewebs.com/moonriver2004 It also shows his sire and dam. Thanks |

Jennifer,
I am so sorry about Huck. What a shame and utter dissappointment for you. Huck is fortunate to have you.
I am unaware of any correlation between roaring and wobblers...or any research that could support that theory. Your best bet (if you wished to pursue it), would be to contact a local veterinary school to see if they have any information.
As you probably already know, wobblers can develop from a variety of causes...genetics, conformation, trauma...one, all, or combinations.
Consulting with your vet regarding breeding would be a good idea. Perhaps they can guide you on whether or not it is adviseable to repeat the same cross (or if it is of issue).
Best wishes,
Heather |

Jennifer, that is awful about your colt. I went and read your page about him. He is beautiful. I hope he does well. Let us know how things go. |

My vet says he doesn't think breeding the two is a big issue. I am just afraid that this will happen again...I'll keep y'all updated. |
