And would you put your mare to a stallion who had sarcoids but he is an up and coming talented comp(dressage) horse????
Are sarcoids hereditary?????

Sarcoids are viral in origin, so in that case I would not think them hereditary

Hmmmmmmmmm... good question. Perhaps the tendency to develop sarcoids is hereditary. I doubt the actual sarcoids are.

They certainly run in families

the grey in my siggy had terrible sarcoids all her life. when she retired (not due to them), first vet i asked said "do NOT breed from her, she will definitely pass them on" etc. then i asked my regular vet who said they are viral and not hereditary, so i
bred from her. unfortunately she had a few big ones right by her udder which the foal used to try and suckle (eww) so it spent the first 2 months of its life with face covered in blood from them, i thought it would be a miracle if it didn't catch them.
at the age of about 4 it had 3 very small ones, really just pimples, which i treated with bloodroot ointment. they went and never came back. she never had any more. her sister, out of same mare, is now 6 and grey and has never had one yet.
they are only contagious to horses of the same blood type, my vet told me.
i would breed from a stallion with them, if he was truly exceptional.

Thanks for your replies everyone!!
I know sarcoids can be malignant (sp?) but are mostly benign and quite unsightly, I know they are viral but I wasnt sure if you had a mare who had sarcoids and bred form a stallion that had sarcoids if it would produce a foal/ horse with sarcoids or more likely to develop them later on in life??
Mmmmm..may have to do some research online......

When I was checking out stallions for my mare I went to see a lovely sporthorse stallion that had evidence of having been treated for sarcoids. Predisposition to sarcoids is probably hereditary, and some horses appear to be genetically resistant, so I was concerned about this too and did a bit of research.
No one has really worked out the details of how it gets passed on as it's quite complicated and involves a number of genes, and after weighing up the risks I decided to use the stallion anyway.
The flip side of this is that since 7-9% of horses in the uk have sarcoids there are a fair few stallions out there that have been treated for them, and the studs aren't going to tell you that (we noticed a few subtle, but characteristic scars on the stallion I used), so you could end up using a stallion that you like less that poses the same risk.

Sarcoids are caused by the pappiloma virus. So theretically are not heredity or contagious.
BUT! Saying that the foal is going to be the same genetic make up of 2 parents that have a low immunity (hence why their bodies have succumbed to the virus) so it is possible that the foal will have a lower immunity & "could" also be suseptible to them.
If that makes any sense!
Also sarcoids "could" be passed to horses but only if they are the same blood type, so to speak.
It is like organ donation, only certain blood types can transpalte to their own blood type. If you put it in to another blood type it will not take, pretty much the same with sarcoids!
Hope that makes sense!!

I have read around this a lot & quite a few people think that you need a combination of 1) genetic susceptibility, 2) infection with bovine papiloma virus & 3) an injury site (though the injury can be a small as a fly bite/thorn prick). I think the only certainty is it's not a straight forward infection/genetic issue. If it is the "3 phase" cause there are likely to be stallions & mares who could pass the risk on but have no sign of sarcoids themselves. Likewise having the risk wouldn't mean the offspring would definitely get it.
If I were choosing between 2 stallions I liked equally I would choose the one without sarcoids, but if there was a stallion who was much more suitable I would choose him despite sarcoids (providing he didn't have loads). I would probably avoid breeding from a mare with sarcoids as I would worry about her's getting worse/developing new ones as a result of pregnancy (don't know if there is any science behind that just my worry)
