Mare - online puzzles
A mare is an adult female horse or other equine.
In most cases, a mare is a female horse over the age of three, and a filly is a female horse three and younger. In Thoroughbred horse racing, a mare is defined as a female horse more than four years old. The word can also be used for other female equine animals, particularly mules and zebras, but a female donkey is usually called a "jenny". A broodmare is a mare used for breeding. A horse's female parent is known as its dam.
An uncastrated adult male horse is called a stallion and a castrated male is a gelding. Occasionally, the term "horse" is used to designate only a male horse.
