Yes, Enzo supposed to be a black Friesian, LOL. Just like the rest of the country. We too have had the horrible heat and more sun than ever in MI. They're claims that some frisians stay black all year and there are variations of many bay colors as most friesians do fade from sun exposure. I have read an article in Horsemans Journal that black horses usually are deficient in copper and zinc. Zinc and copper help grow a healthy and strong hair shaft that won't bleach out as easy when it is healthy. These are also responsible for healthy hooves as well. So I have added zinc and cooper to Enzo's diet. But I started off with a small amount and maybe too late this spring?? But either way, I thought I would try it. I just increased the dose yesterday and of course, I will wait to see in anything changes in Enzo's coat color this fall. I also added some oil, but the sun rays just seem to be stronger, LOL. Also some Friesian people leave their horses in during the sunny day to keep their horses from bleaching. But I could never do that to my horse, just to keep him black. These pictures were taken today to give you an idea of how bleached Enzo is as of Aug 2011. Anybody else have remedies to keep their horses dark???
