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, as this term refers to horses that have never 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.
A gelding is a castrated male horse or other equine, such as a pony, donkey or a mule. The term is also used with certain other animals and livestock, such as domesticated camels. By comparison, the equivalent term for a castrated male bull would be ox, or a wether for rams and billy goats.
The Arabian or Arab horse is a breed of horse that originated on the Arabian Peninsula. With a distinctive head shape and high tail carriage, the Arabian is one of the most easily recognizable horse breeds in the world. It is also one of the oldest breeds, with archaeological evidence of horses in the Middle East that resemble modern Arabians dating back 4,500 years. Throughout history, Arabian horses have spread around the world by both war and trade, used to improve other breeds by adding speed, refinement, endurance, and strong bone. Today, Arabian bloodlines are found in almost every modern breed of riding horse.
A filly is a female horse that is too young to be called a mare. There are two specific definitions in use:
A foal is an equine up to one year old; this term is used mainly for horses, but can be used for donkeys. More specific terms are colt for a male foal and filly for a female foal, and are used until the horse is three or four. When the foal is nursing from its dam (mother), it may also be called a "suckling". After it has been weaned from its dam, it may be called a "weanling". When a mare is pregnant, she is said to be "in foal". When the mare gives birth, she is "foaling", and the impending birth is usually stated as "to foal". A newborn horse is "foaled".
The Haflinger, also known as the Avelignese, is a breed of horse developed in Austria and northern Italy during the late 19th century. Haflinger horses are relatively small, are always chestnut with flaxen mane and tail, have distinctive gaits described as energetic but smooth, and are well-muscled yet elegant. The breed traces its ancestry to the Middle Ages; several theories for its origin exist. Haflingers, developed for use in mountainous terrain, are known for their hardiness. Their current conformation and appearance are the result of infusions of bloodlines from Arabian and various European breeds into the original native Tyrolean ponies. The foundation sire, 249 Folie, was born in 1874; by 1904, the first breeders' cooperative was formed. All Haflingers can trace their lineage back to Folie through one of seven bloodlines. World Wars I and II, as well as the Great Depression, had a detrimental effect on the breed, and lower-quality animals were used at times to save the breed from extinction. During World War II, breeders focused on horses that were shorter and more draft-like, favored by the military for use as packhorses. The emphasis after the war shifted toward animals of increased refinement and height.
A colt is a male horse, usually below the age of four years.
A stud animal is a registered animal retained for breeding. The terms for the male of a given animal species usually imply that the animal is intact—that is, not castrated—and therefore capable of siring offspring. A specialized vocabulary exists for de-sexed animals and those animals used in grading up to a purebred status.
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 stud farm or stud in animal husbandry is an establishment for selective breeding of livestock. The word "stud" comes from the Old English stod meaning "herd of horses, place where horses are kept for breeding". Historically, documentation of the breedings that occur on a stud farm leads to the development of a stud book. Male animals made available for breeding to outside female animals are said to be "standing at stud", or at "stud service", referencing the relatively high probability that they are kept at a stud farm.
The Kladruber is the oldest Czech horse breed and one of the world's oldest horse breeds. It is considered very rare. The chief breeder and the keeper of the studbook is the National Stud at Kladruby nad Labem in the Czech Republic where Kladrubers have been bred for more than 400 years. Kladrubers have always been bred to be a galakarossier – a heavy type of carriage horse for the court of the House of Habsburg.
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.
Rags to Riches is a champion American Thoroughbred racehorse who won the 2007 Belmont Stakes, the first filly to win it in over a century.
The Campolina horse breed of Brazil is named after Cassiano Campolina, the farmer who developed the breed. Beginning in 1870, they were developed using several different breeds of horses. The Campolina is one of the larger Brazilian breeds, and may be found in most colors. They are a gaited breed, with an ambling gait. They are used mainly for leisure riding and driving and are increasingly used for dressage within Brazil.
An Austrian Warmblood is a warmblood type of horse registered with the Arbeitsgemeinschaft für Warmblutzucht in Österreich. Although the studbook is made up of jumping and dressage horses from many other countries, the mare base consists of native horses with a long history. The AWÖ keeps an open studbook, in which mares and stallions must pass rigorous inspections before becoming breeding stock.
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.
The Zweibrücker is a type of German warmblood horse bred in Rhineland-Palatinate and Saarland. Traditionally, the breeding of Zweibrücken was centered on the onetime Principal Stud of Zweibrücken but since 1977 has been under the jurisdiction of the Horse Breeders' Association of Rhineland-Palatinate-Saar (PRPS). The modern Zweibrücker is an elegant, large-framed, correct sport horse with powerful, elastic gaits suitable for dressage, show jumping, eventing and combined driving.
Thoroughbred breeding theories are used by horse breeders in an attempt to arrange matings that produce progeny successful in horse racing. Bloodstock experts also rely on these theories when purchasing young horses or breeding stock. A basic understanding of these theories can also help the racing public understand a horse's theoretical genetic potential. The breeding theories stem from the belief that careful analysis of bloodlines can lend predictability to breeding outcomes. A well-designed mating increases the probability of the offspring's success, although many other factors also come into play.
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).
