Sure I'll tell yall what I know, which isn't much. I've seen 3 horses with it. Looks like the hoof has been melted. Like you put it in a fire and it melted like plastic. It looks a little like founder, but the hoof wall sinks in instead of separating. Well, some separation, but not much. The sole drops like a laminitic horse. All cases I saw had severe cracks also, which soon became infested with white line disease.
There was no common denominator with the horses I saw affected, except I remember one of them had just been brought in from Oklahoma. Maybe more selenium in the hay/grass caused a shock to it's system. In all cases there were at least 5 other horses on the farm that weren't affected. Selenium is a required in small amounts, but an overdose causes problems. It's supposedly more common in young horses, but all the ones I saw were mature.
It's a good idea to have the soil checked by USDA/NRCS for toxidity
When I bo't my Arab his hooves were much worse than those and we discovered he preferred to walk backward because of long "shards" of hoof. Since my farrier was doing the trailering he trimmed him up to a pretty decent hoof under the circumstances before we loaded him.
I don't think it's up to the BO to be doling out advice on horse care, unless of course it is requested. It is the owner's responsibilty to have the hooves attended to. Some folks get their panties in a twist should advice be offered.
If that is on fact an actual circumstance (such poisoning causing a hoof to appear to "slide off", as this photo shows the left front kind of appearing (I agree, though I will admit I am ignorant to selenium poisoning, however am not going to be for long...off to research such momentarily!!) would the right front not also share the same/similar appearance, or does it effect only one hoof at a time? You wouldn't happen to have any research/literature/other photo links to similar cases, would you?
I imagine we could ALL LEARN A LOT about this which isn't widely known, apparently. Thanks...B2H Posted via Mobile Device
