Curious about how widespread this has become: Do breeders now routinely test their broodmares and stallions for ECVM?
by test, do you mean xray? there’s no genetic marker identified yet.
Yes, there’s now a specific x-ray protocol for identifying the cervical vertebra malformation.
I wish they would!
Granted I’m not deep in the breeding world, but AFAIK no one is doing this as a matter of course. It’s not like the 5 panel tests and that sort of thing.
Not to mention that the veterinary community isn’t really confident on what sort of X-ray = clinical issues. At least not yet.
