Which term describes a castrated male horse?

• A. Colt
• B. Stallion
• C. Gelding
• D. Filly

Answer: (C)

Understanding horse terminology based on sex, age, and castration helps identify the right name. When a male horse has been castrated, the animal is called a gelding. This term applies regardless of age, distinguishing castrated males from others. In contrast, a colt refers to a young male horse that is typically uncastrated, a stallion is an adult uncastrated male used for breeding, and a filly is a young female. So the castrated male horse—the one described here—is best described as a gelding.
