One of the herd got appearantly bit by a snake sometime yesterday afternoon. By the time I found him in the evening, his muzzle was grotesquely swollen, upper lip protruding over the lower by several inches. The swelling was centered on his lower left cheek below the eye, and he appeared to be having some trouble breathing. On the other hand, he was still standing up and walking, and had an active interest in the grain bucket, though he couldn't actually eat any.

We administered echinacea tincture and sugar (20mL)and left him in the paddock last night. This morning, the swelling is down noticeably and he whinneyed when we came in sight.

I'm not sure it was the echinacea, per se, as it probably did a bit of good; it's probably a case of him being a very big horse and the snake being a very small one.
 

And if it was the snake; size would have little to do with the results. For example; a coral snake isn't much bigger than a bracelet in length but can kill a man in seconds. I will agree that size might have something to do with how long the venom would take to kill a large animal such as a horse.

So how big was this horse? A draft horse or a 16 hand plus Thoroughbred? I'm curious.
