Sorry to drag up this older post but I just wanted to correct some misinformation.
I have had Am. Cream Drafts since 1992 so I do believe, though not an expert by any means, I know a little about them.
Off colored horses are registerable as Tracking. They are not euthanised. There is no reason to euthanise a horse that can still be useable if not registered.
ACD stallions MUST have pink skin to be registered as ACD. If they have dark skin, they can be gelded and then registered. We have the tracking option to keep track of who creates what. It is invaluable information.
Mares can be registered whether or not they have dark skin. We need their genetics yet due to the low number of living animals which is maybe 400 or so. Because of outcrossing to bring in fresh genetic material we also have issues with color once in awhile. I have raised 11 foals and they have all been champagne varying from light to dark.
Not all have very light eyes. That too can vary from the light hazel shown on that pinto to dark. All champagne foals are born with "white" eyes and they darken with age to hazel to brown.
The assoc. Still allows outcrossing until we get to at least 500 living animals before we dare close the genetic books. And now with the threat of JEB running through the breed brought in by crossing to Belgians who knows where we are at. The assoc. Is working carefully with Dr. Phillip Sponenberg and the University of KY to determine when the assoc. Can close the books to outcrossing.
