What is the life expectancy of a horse?
Horse
Foal: A foal of either sex less than one year old. A nursing foal is sometimes called a suckling and a foal that has been weaned is called a weanling.[13] Most domesticated foals are weaned at five to seven months of age, although foals can be weaned at four months with no adverse physical effects.[14]
Yearling: A horse of either sex that is between one and two years old.[15]
Colt: A male horse under the age of four.[16] A common terminology error is to call any young horse a "colt", when the term actually only refers to young male horses.[17]
Filly: A female horse under the age of four.[13]
Mare: A female horse four years old and older.[18]
Stallion: A non-castrated male horse four years old and older.[19] The term "horse" is sometimes used colloquially to refer specifically to a stallion.[20]
Gelding: A castrated male horse of any age.[13]
