HYPP NN

Hey everyone. Question! lol My vet who is a good friend of mine (bless her heart) also happens to be a HUGE know-it-all and sometimes annoys me. lol I was posting on FB regarding my anger towards a person who just bred a lethal white and I was sort of venting about these sorts of things being preventable. I mentioned that with testing, HYPP, HERDA and OLWS are all preventable. She of course, had to chime in: # All Around Equine I have seen a few [b](referring to a lethal white foal)[/b] # Robin C. Benefiel I have as well. Its just plain irresponsible to not test though, it isn't expensive. Its preventable just like HYPP and HERDA. # Sarah Mason look at the lady I bought freya from...she didnt test for jeb and her foal died # All Around Equine HYPP is not 100 % preventable # All Around Equine A N/N can still show symptoms. # Robin C. Benefiel Do you mean N/H? NN means there is no sign of it and therefore unless a spontaneous mutation occurs it will not technically be HYPP. # All Around Equine No have seen N/N with HYPP. Ok, so... is this true? Anyone heard of it? I asked her if she technically meant exertional rhabdomyolysis but I know she'll say no. She's making it sound like this happens a lot... I'm now very confused. Thanks guys!

NO NO NO NO NO.

NN means there is NO HYPP present. Meaning they do NOT have HYPP.

They could potentially have another mutation that presents similar symptoms, but it is NOT HYPP.

NN's do NOT have symptoms. If a true NN has symptoms, then it needs to be tested for PSSM, which is a totally different genetic disorder. (I think that's the other disease which has similar symptoms.

And it is totally "preventable"--do not breed anything that is HyPP positive and it'll disappear. My email from Dr. Spiers on the subject is on the Bringing Light to HyPP website.

If she is a vet, she should absolutely know that an NN horse is not going to have an HyPP attack. Absolutely not. No way. Not going to happen.

So Swinghorse, is that you as "Robin"? I don't want to send a friend request to the wrong person! (Lady Hawke on FB).

Right now I think she is thinking I'm some idiot who really doesn't know anything... anyone who has a FB willing to pipe in on my thread? It should be public and you can comment on it. :)

[Edit]: She deleted all her comments... lol

This!!! We tested and retested twice my friends Pally mare that I've posted pictures of before. She has what we suspect is PSSM. The test isn't as easy as a DNA test for HYPP though, it's a fairly invasive muscle biopsy.

IMO and experience PSSM is WAY WORSE and more likely to kill HYPP. I've been around both, multiple times and the PSSM attacks are scary and from what I've seen far less manageable through diet and exercise than HYPP and FAR FAR more painful :(

I thought PSSM has a new test that's not as invasive? I'll have to check with someone I know who has been doing a fair bit of PSSM testing as it appears to be in the Dreamfinder bloodlines.

There is now a genetic test for PSSM rather than having to do a muscle biopsy. The genetic test only covers 85-90% of affected horses if I recall correctly as it is only for PSSM type 1.

Is she nuts?
If it tests N/N it can't have HYPP- that is the [i]whole[/i] point of testing for a disease of any kind, of testing for [i]anything[/i] as a Vet she should not only know this but it would make me doubt anything at all that she said after this!
It is not rocket science, it is self explanatory.
I sometimes wonder if there is hope for the world when they let people out of Vet School without the very bottom line basics straight in their heads!!

DANG! I wish I had known this a year ago!

PSSM is miserable. Having seen both PSSM and HYPP attacks, I FIRMLY believe that PSSM is the more dangerous and painful of the two.

Watching that mare cramp up like that was horrific. Add to that the tying up, discomfort urinating and how difficult it is to manage.... I'll take an HYPP horse ANY DAY over a PSSM horse. Even with crazy researched and rigorously managed diet and exercise, it can be very hard to control :( *MOST* HYPP attacks are a drop in the bucket comparatively and the ones I've been around don't seem NEARLY as painful to them. Most of the time the horse continues on like nothing's happening and is fine afterwards. Poor Idgie was always exhausted after her attacks.

I'm glad there's a genetic test now, we can start to weed it out better!

Sorta. lol She's definitely on something (has been agreed upon by hubby and my best friend). She's great for surgery and injuries and we use her for confirmed pregnancies, etc but as far as foaling out, genetics and handling a breeding stallion... I'm guessing she didn't pay as much attention in class.

We always collect our own horses but the other day a person paid her and us to use our facilities to collect their stud. She did the collection and as soon as the horse finished, she ran into the office without covering the bottle and exposed all the semen in the sun for over 30 seconds or more. I sorta wanted to slam my head into the barn wall. I couldn't believe her. All the semen was dead!
