Eclampsia: calcium deficiency in a lactating mare. Can cause convulsions and coma associated with hypertension, endema, and/or excess protein in the mare's urine. It usually occurs around two weeks after foaling and is associated with lactation and stress.

High-protein, high-calcium diets help mares that are prone to eclampsia

Enterolith: an intestinal stone that can form in the horse's digestive tract.

Then, to keep that matter from injuring the intestine, the horse's body forms a layer around it, then another, and another; if the stone is not passed out with manure, it will continue to grow larger until it eventually kills the horse. The formation of enteroliths can also be affected by many other things, such as diet, exercise, and genetic predisposition.
