The first domesticated horse I ever saw was a bay gelding, and it was standing next to the corral, nibbling sugar cubes from Shawn's hand. It was spring, and I was fourteen. It had been many years since I'd touched a horse.
A gelding is a castrated horse or other equine, such as a donkey or a mule. Castration, as well as the elimination of hormonally driven behavior associated with a stallion, allows a male horse to be calmer and better-behaved, making the animal quieter, gentler and potentially more suitable as an everyday working animal. As a verb, "gelding," or "to geld," refers to the castration procedure itself.
