hypp breeding
In light of the recent conversation of whether or not it is responsible or not to breed a hypp mare, I thought I'd post this for folks who just don't get it.

Please be warned that it is graphic in nature.

thats not a nice video..i think it would be VERY irresponasible to breed from a hypp mare..i dont know anything about this disorder [besides the caption that comes up],the poor girl couldnt even get up. very sad!

Thats a distressing/upsetting video. :cry:

I'd not heard of it before, well until I joined the Horseforum.

How long does each period last? Can it be fatal?

My first question is why didn't the person do anything to try and stop the situation or at least get the baby out. I know they where trying to get a video, but safety first. I have a mare that is hypp and she has had only one episode and I gave her Karo syrup and she was fine. This was only after I took her off her meds. So I now keep her on her meds and she is fine. I don't want to start a big stink, but everyone has their opinion on this matter. I like these horses, but you have to know what your getting into with these horses when you buy one. I know others think they should be done away with, but it's going to be nearly impossible to do that. I look at it this way. If you have a child that has a bad disease are you going to end it's life or not have any more children. I don't think so. Just because my mare has this disease doesn't mean she has to be put down. She is the most loving and spirited horse.

From the AQHA website:

• Hyperkalemic periodic paralysis (HYPP) is an inherited disease that leads to uncontrolled muscle twitching or profound muscle weakness, and in severe cases, may lead to collapse and/or death.

• HYPP is listed as a genetic defect in AQHA's rules, along with Parrot Mouth and Cryptorchid conditions.

• To date, HYPP only has been traced to descendants of IMPRESSIVE, #0767246.

•HYPP can be treated through diet and medication in most cases.

• Possible results of HYPP testing are N/N, N/H and H/H.
HYPP is inherited as a dominant trait, which means a heterozygous (N/H) stallion or mare bred to a normal (N/N) horse will result in approximately half of the offspring being affected and half being normal. The rare homozygote (H/H) usually is severely affected with the disease and will pass the gene to its offspring 100 percent of the time.

An informative page:

This link has a good discussion of opinions on whether or not people should breed hypp horses. Included in the article is this quote:


According to Dr. Sara Caldwell. DVM, Ocala Florida, a graduate of Florida State University, College of Veterinary Medicine, “The non riding myth is propagated by the veterinary teaching schools, We are actually taught and directed in school to discourage clients from riding HYPP horses in order to protect ourselves, veterinarians, from possible legal action, should an accident occur. Not at all for reasons of veterinary health or management, it is strictly a legal issue.”
That's a pretty sad statement in regards to veterinarians in general, wouldn't you agree?

My personal thought is that, just because you can't always see it, doesn't mean you should regard your hypp horse as breeding stock. Those who continue to pass on this gene, regardless of how mild it may be in their horse, are breeding just as irresponsibly as the backyard dog breeder who breeds an animal with poor hips. You may not see it on the outside, and you may win in the ring, but we certainly ought not be passing along poor genetics just to win.

I think we should aplaud AQHA for stopping the registration of HYPP H/H horses and maybe eventually stop the registration of N/H horses as well, which will make these horses pretty much undisireable as they will no longer be able to show at the aqha shows, they will basically be local show disasters as most ppl who show the smaller local and open shows are typically people who arent that serious and may not be as well informed, unlike the big timers who write it off as really being no big deal. Look at 07 h/h babies for sale, you can find a young stud on, for example, who is being marketed as "super local show horse for anyone" He's a 1000 bucks and on medication. Anyways im sorry im getting a bit off track here! People arent goin to breed undisireable horses they wont get any money out of it, so if there smart they will stop! I don't think we should do away with the hypp horses we already have (i know 3 hypp n/h horses and i think they all fantastic horses and they make there owners very happy)but why keep breeding for a genetic disease. Comparing a diseased child and a diseased horse really isnt fair, i mean if your kid breaks his leg pretty bad your surely not putting him down but as for the horse goes....( i know we can fix a lot of broken legs n stuff now but your missin the point if you look that far into it) Im sorry if it sounds like im goin off here im really not meaning to, but i think alot of people are very mis-informed about hypp and think its really no big deal when it can be. But Zipster did make a very good point about people needing to know what there gettin into when they do get a hypp positive horse and i think if people want to keep breeding these horses they need to go above and beyond to make sure there clients are well informed! I could go on about this forever so im goin to shut up now!

Good post, dear. :wink:

I don't know how many of you read the fuglyhorseoftheday blog (I love it). She wrote this about hypp and I think she did a great job explaining how serious this disease is. http://fuglyhorseoftheday.blogspot.c...n-genetic.html

Any moron who would breed a horse knowing that they are hypp positive is sooo irresponsible and horrible.

. Just because my mare has this disease doesn't mean she has to be put down.
no one is saying they should be put down,its just about breeding from them,you say you have a mare,would you breed from her?
