View Full Version : HERDA - (Mature with talk of gore-ish-ness)

So I was browsing Horsetopia.com - and went onto their forum.
I see often, when they are talking about AQH checking for "HERDA"

Well, I didn't know what that was.
Once, my friend, SR, told me to watch out on QH (and/or paint lines) because one stallion had passed on a disease to his offspring which is recessive generally, but can assault the back. I took it to heart, but never found out what it was called.

I know what she was talking about now.

HERDA is a disease which makes the skin along the neck, back, hips and sometimes lower legs of a horse easily torn. (o.o!) It doesn't heal back properly, it's too pull-aparty and you can't stitch it back together.
Some horses have 'de-gloved' their skin! (From rolling or something, the skin sloughs down the sides o.o')

Does anyone know who the HERDA stallion is that started it all? I want to avoid the line :/
And, would anyone know how much it takes to get a breeding stock/foundation/whatever QH tested for it? (along with N/N stuff - whatever that is xD)

hm, i've never heard of a HERDA issue. i know the stallion Obvious Conclusion passed down a disease [although i think it was recessive, too], but it's not HERDA. i don't remember what it's called, but it's not that [i actually board at the stables where Obvious Conclusion used to be at stud, lol]. it's more like seizures and such.

i don't know how much it costs to test; i don't have a quarter horse and my grandparents' qhs don't have those lines. sorry!

Poco Bueno is the known sire of hyperelastosis cutis (HC) or hereditary equine regional dermal asthenia (HERDA). HERDA occurs when two horses with similar Poco Bueno lines are mated (such as distant cousins). Essentially there is a lack of adhesion within the dermis (the deepest layer of skin) because of a collagen defect. When trauma occurs (even minor such as riding) the outer skin seperates from the dermis. These horses usually lives two to four years.

Ah.. Charming x.x
But, I don't know if I'd take the HERDA disease over that.. unless it seriously could kill the animal..

Ah, thanks :)
I'll keep that name in mind when I'm going through QH's
Thanks again

the Impressive bloodline is the line that carries HYPP. if you are looking at a potential horse, and you see that he has Impressive in his bloodline the owner is required to tell you if he is N/N (negative), N/H (50/50%), and H/H(100%).

this is an excerpt from a study from UC Davis:

The trait is inherited from generation to generation with equal frequency; it does not get "diluted" out. Breeding an affected heterozygous horse (N/H) to a normal horse (N/N) will result in approximately 50 percent normal offspring, while 50 percent will carry the defective gene (N/H). Breeding an affected homozygote (H/H) will result in all offspring carrying the gene mutation, regardless of the status of the other parent.

I have never in my life heard of that?!?! Is it like genetic??
