I’m wondering if anyone has seen or heard of this before, as I have not and can’t even find any information on it anywhere on the world wide web.
Friday night I said goodbye to my beloved horse, Lightning. He was 27 years old, and a degenerative bone cyst in his knee finally compromised his quality of life. We put him down ourselves and buried him in the pasture. He was dispatched by gunshot, which was instantaneous. I confirmed that he did indeed die instantly. I don’t know how long it was after the shot (as I was bawling my face off) but after a minute or more the death throes of the nervous system began, during which a large amount of blood gushed from his nose while his hind legs paddled. I know it sounds awful, but my dear Lightning was gone, and the body was just doing what bodies do.
I only even mention this because the next morning I turned my other two horses out onto the pasture. They made their way over to Lightning’s resting place. Once they discovered the blood-soaked grass they both proceeded to EAT IT. For close to 10 minutes they stayed on that spot and ate the bloody grass, really getting into it with their lips.
4 days later they still return to that spot and at least one of them is still eating the grass in that spot. He really doesn’t appear to enjoy it, but they’ve eaten it right down to the bare dirt in spots.
Has anyone ever heard of this?! One theory is that it might have to do with scent, and wanting to remove any trace of blood smell, but for one there is no way they could ever successfully do that, and for another it doesn’t seem to have much evolutionary benefit. I get why mares will eat the placenta - the foal will be on the ground for at least a short time and will be unsteady on its feet for the first little while, nevermind the dam won’t be moving too fast as she recovers from the birth. It makes sense to want to eliminate the placenta so there is no scent or benefit to a predator coming around. But horses in the wild are always on the move - they would just leave the area if an herd-mate was killed.
Another theory is that maybe it is the iron or something in the blood that they are craving? Either way, I’ve never heard of it and can’t find any mentions of anything like this. Probably the weirdest thing I’ve seen a horse do!
