What is a female horse called?

A female horse is referred to as a mare. This term is used specifically for adult female horses, typically those over three years of age. Understanding the terminology associated with horses is essential in the equine world, as it helps identify the age and gender of these animals, which can influence their care, breeding, and training needs.

The term "filly" also pertains to a female horse but is used for younger females, usually those under three years old. A "colt" is a young male horse, while a "stallion" refers to an adult male horse that has not been castrated, which allows for breeding. Knowing these distinctions helps in effectively communicating about equine management and breeding practices.
