What is geophagia in horses?
Geophagia refers to eating dirt and is reported to be fairly common in feral horses. Geophagia is not simply horses taking in dirt while grazing close to the ground or eating grain off the ground; it is a behavior where horses actively bite into the ground specifically to eat dirt. Anecdotal evidence indicates dirt-eating may be more common in stallions than mares or geldings, but no studies of gender effects on geophagia have been reported.
