A gelding is a castrated male horse or other equine, such as a pony, donkey or a mule. The term is also used with certain other animals and livestock, such as domesticated camels.[1] By comparison, the equivalent term for castrated male cattle would be steer (or bullock), and wether for sheep and goats.
Castration allows a male animal to be more calm, better-behaved, less sexually aggressive, and more responsive to training efforts. It is known for making the animal generally more suitable as an everyday working animal, or even as a pet (in the case of companion animals).[2] The gerund and participle "gelding" and the infinitive "to geld" refer to the castration procedure itself.
...in the US, expect to spend around $10,000 for a mature gelding and up to $17,000 for a pregnant female.
