A castrated equine is called what?

A castrated equine is called a gelding. The term "geld" refers specifically to the process of castration in males, which involves the removal of the testicles. This procedure is commonly performed to prevent unwanted breeding behaviors and can lead to calmer temperaments, making geldings more suitable for various forms of work and riding.

In contrast, a colt refers to a young male horse that has not yet been castrated, typically under the age of four. A stallion is an intact male horse that can breed, while a mare is a mature female horse. Understanding these distinctions is important for recognizing the roles and classifications of equines in both breeding and training contexts.
