dit heb ik er tot nu toe over gevonden
lood Marks or Bloody Shoulder
This is a rare effect that usually happens in the Arabian breed, but can occur in any breed that has the greying gene in it's gene pool.
Blood marks are basically a very large concentration of fleabites in a particular area of the horse, that can enlarge as the horse ages. These horses are sometimes referred to as a "Bloody Shouldered Grey".
If you have a photo of a Blood Mark you would like to contribute to this site, please send it to info@equinecolor.com
The painting on the bottom left is John Wootton's picture of Lord Oxford's Bloody-Shouldered Arabian, a Grey with a dark "Roan" stain. It was suggested that these markings were caused prenatally by an accident to the horse's dam. We know now that this is just a concentration of fleabites.
maar, wat zijn die fleabites dan? Verder is ze nl niet echt vliegerig op dr lijf zeg maar, af en toe een verdwaald stipje, maar geen echte vliegenschimmel
