What is the term used for a female horse?

The term used for a female horse is "mare." This classification is important in equine terminology, which categorizes horses based on age and gender. A mare is typically an adult female horse, usually over the age of three.

In contrast, a "stallion" refers to an adult male horse, while "colt" is used to describe a young male horse, typically under the age of four. The term "filly" specifically refers to a young female horse, usually under the age of four, before she becomes a mare. Understanding these terms is essential for anyone studying or working in the field of livestock, particularly in managing and breeding horses.
