What is the title for a mature female horse?

A mature female horse is referred to as a mare. This terminology is widely used within the equine community and helps distinguish between different genders and ages of horses. A mare is typically over the age of three, which differentiates her from younger female horses, known as fillies.

In contrast, a stallion is a mature male horse that is capable of breeding, while a colt refers to a young male horse, generally one that is under three years old. Understanding these terms is essential for effective communication in animal science and horse management, as it allows for clarity when discussing the age and gender of horses.
