The horse is a domesticated, one-toed, hoofed mammal. It belongs to the taxonomic family Equidae and is one of two extant subspecies of Equus ferus. The horse has evolved over the past 45 to 55 million years from a small multi-toed creature, close to Eohippus, into the large, single-toed animal of today. Humans began domesticating horses around 4000 BCE, and their domestication is believed to have been widespread by 3000 BCE. Horses in the subspecies caballus are domesticated, although some domesticated populations live in the wild as feral horses. These feral populations are not true wild horses, which are horses that never have been domesticated. There is an extensive, specialized vocabulary used to describe equine-related concepts, covering everything from anatomy to life stages, size, colors, markings, breeds, locomotion, and behavior.
Horse breeding is reproduction in horses, and particularly the human-directed process of selective breeding of animals, particularly purebred horses of a given breed. Planned matings can be used to produce specifically desired characteristics in domesticated horses. Furthermore, modern breeding management and technologies can increase the rate of conception, a healthy pregnancy, and successful foaling.
Weaning is the process of gradually introducing an infant human or another mammal to what will be its adult diet while withdrawing the supply of its mother's milk.
A filly is a female horse that is too young to be called a mare. There are two specific definitions in use:
A weanling is an animal that has just been weaned. The term is usually used to refer to a type of young horse, a foal that has been weaned, usually between six months and a year. Once it is a year old, the horse is referred to as a yearling.
Horse training refers to a variety of practices that teach horses to perform certain behaviors when commanded to do so by humans. Horses are trained to be manageable by humans for everyday care as well as for equestrian activities, ranging anywhere from equine sports such as horse racing, dressage, or jumping, to therapeutic horseback riding for people with disabilities.
A colt is a male horse, usually below the age of four years.
A stallion is a male horse that has not been gelded (castrated). Stallions follow the conformation and phenotype of their breed, but within that standard, the presence of hormones such as testosterone may give stallions a thicker, "cresty" neck, as well as a somewhat more muscular physique as compared to female horses, known as mares, and castrated males, called geldings.
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.
Sky Beauty was a thoroughbred horse who won the 1993 Triple Tiara of Thoroughbred Racing. As of 2018, she was the last filly to win this title.
Horse behavior is best understood from the view that horses are prey animals with a well-developed fight-or-flight response. Their first reaction to a threat is often to flee, although sometimes they stand their ground and defend themselves or their offspring in cases where flight is untenable, such as when a foal would be threatened.
Holy Roller was an Australian Thoroughbred racehorse of the mid-to late 1990s. He won 12 of his 25 races and a developed a cult following amongst Sydney race fans. Bred and owned by Woodlands Stud, Holy Roller stood 18.1 hands, compared to the average thoroughbred at around 16 hands. His career highlights included wins in the Bill Ritchie Handicap and the Crystal Mile.
A yearling is a young horse either male or female that is between one and two years old. Yearlings are comparable in development to a very early adolescent and are not fully mature physically. While they may be in the earliest stages of sexual maturity, they are considered too young to be breeding stock.
Mountain and moorland ponies form a group of several breeds of ponies and small horses native to the British Isles. Many of these breeds are derived from semi-feral ponies kept on moorland or heathland, and some of them still live in this way, as well as being kept as fully domesticated horses for riding, driving, and other draught work, or for horse showing.
Studbook selection is a process used in certain breeds of horses to select breeding stock. It allows a breed registry to direct the evolution of the breed towards the ideal by eliminating unhealthy or undesirable animals from the population. The removal of individuals from a population is called culling, and does not suggest killing the animal in question. Typically, culls are castrated or they and their offspring are unable to be registered.
A pony is a type of small horse. Depending on the context, a pony may be a horse that is under a given approximate or exact height at the withers, or a small horse with a specific conformation and temperament. Compared to a larger horse, a pony may have a thicker coat, mane and tail, with proportionally shorter legs, a wider barrel, heavier bone, a thicker neck and a shorter, broader head. The word pony derives from the old French poulenet, meaning foal, a young, immature horse.
This is a basic glossary of equestrian terms that includes both technical terminology and jargon developed over the centuries for horses and other equidae, as well as various horse-related concepts. Where noted, some terms are used only in American English (US), only in British English (UK), or are regional to a particular part of the world, such as Australia (AU).
Dancing Rain is a retired Thoroughbred mare that was bred in Ireland and raced in the United Kingdom, Ireland, Germany and Japan. Dancing Rain was the unanticipated winner of the 2011 Epsom Oaks and won the Preis der Diana in the later part of her three-year-old season. Her form faltered late in her three-year-old year, finishing 16th out of a field of 19 horses in the Queen Elizabeth II Commemorative Cup in Japan. Her four-year-old season was plagued with injury and she did not run in a race until late October 2012. Retired at the end of 2012, Dancing Rain became a broodmare at Clairemont Stud in Hampshire and was subsequently sold to Sheik Mohammed bin Rashid Al Maktoum for £4.2m while in foal to Frankel.
Gamos (1867–1893) was a British Thoroughbred racehorse that won the 1870 Epsom Oaks. Sold to William Graham as a yearling, Gamos won six out of eight starts as a two-year-old in 1869, but failed to improve her racing form after the 1870 Oaks. Gamos raced until she was four-years-old and retired from racing in 1871. Gamos was not successful as a breeding mare and died in 1893 after being sold for £15 in 1890.
Littleprincessemma is a Thoroughbred mare who raced twice but is notable as the dam of the American Triple Crown-winning racehorse American Pharoah. Bred by Brereton C. Jones, she sold in 2006 as a weanling filly for $135,000 and then the following year, as a yearling, she was purchased by Zayat Stables for $250,000. She was named after Ahmed Zayat's daughter, Emma. She is a chestnut with a blaze on her face, a stocking on her left hind leg and a sock on her right hind leg.
