I was looking at a website and they have listed at stud, a purebred Friesian stallion who is a Chestnut. I searched and found there are actually four known living chestnut Friesians that are completely purebred. I also found that the registries for Friesians basically had a fit that these chestnut foals were born and BANNED any stallion that did not test homozygous for black (Basically Ee instead of EE) from breeding! Apparently, they did not test any mares. My question is, why on earth would they do that? It is very simple to prevent the chestnut from reappearing if it is that big a deal by knowledgeable breeding. The Friesian is a very rare breed with a VERY small genepool so why limit the bloodlines even further by banning approved stallions just becuase they carry the gene for red. Again, just because they CARRY it, does not mean it has to show up! Just make sure the stallion is bred to homozygous black mares and they will NEVER have another chestnut foal. Still, I don't see what the huge deal was about a few chestnut Friesians being born. Yes, I understand the standard is for black, but still, it seems a little silly. The Lippizan stallions were bred exclusively for gray (white), but you still get an occasional bay or black that appears and stays that color. The U.S. likes them, though I don't believe Europe is fond, but still the registries did not ban any stallion or mare that had a non-gray foal or refuse to allow the non-grays full regisitry. As I understand it, you can only registered a chestnut Friesian in a foal book, basically as coming from a purebred mare. Other than that, they are not registered, even if they have good conformation or anything else. Again, I just find that to be unwise. Discussions have already been had of why small genepools cause trouble, and the Friesian is already in trouble for new blood and having problems because of that. Why limit what little is left for something so easy to "fix" and control?
