A mare is an adult female horse, typically over the age of three. Mares are known for their nurturing behavior, especially when they give birth to foals. They can be found in various breeds, each with unique characteristics and purposes, such as riding, racing, or work. Mares usually have a reproductive cycle that lasts about 21 days, during which they can become pregnant. The gestation period for a mare is approximately 11 months, after which she gives birth to a foal. Proper care and management are essential for the health and well-being of both the mare and her offspring.
