A kid-friendly fact about horses is that there are around 400 different breeds of horses. These breeds specialize in many different things from racing to cart-pulling. The domestication of the horse occurred about 4,000 years ago amongst Asian nomads. However, wild horses still remain to this day.
While wild horses can be found in many parts of the world, the free-roaming mustangs in North America are direct descendants of imported European horses. The only breed of horse that has never been domesticated was the Przewalski horse. These horses today only exist in captivity, with the last wild horse having been spotted in Mongolia in 1968.
Horses are herbivores. Since they require a constant flow of nutrients, horses graze on vegetation and grass throughout the day, with a 1,000 pound horse eating anywhere from 15 to 24 pounds of food daily. They live on average 25 years and weigh from 840 to 1,200 pounds. However, the biggest and heaviest horses can weigh up to 2,200 pounds.
A male horse is called a stallion, while a female horse is called a mare. A young male horse, under the age of 4, is referred to as a colt and a young female as a filly.
A horse can gallop at 27 miles per hour, with the fastest recorded speed being at 55 miles per hour.
