The American Quarter Horse, or Quarter Horse, is an American breed of horse that excels at sprinting short distances. Its name is derived from its ability to outrun other horse breeds in races of 1⁄4 mi (0.40 km) or less; some have been clocked at speeds up to 44 mph (71 km/h). The development of the Quarter Horse traces to the 1600s.
A horse breed is a selectively bred population of domesticated horses, often with pedigrees recorded in a breed registry. However, the term is sometimes used in a broader sense to define landrace animals of a common phenotype located within a limited geographic region, or even feral "breeds" that are naturally selected. Depending on definition, hundreds of "breeds" exist today, developed for many different uses. Horse breeds are loosely divided into three categories based on general temperament: spirited "hot bloods" with speed and endurance; "cold bloods," such as draft horses and some ponies, suitable for slow, heavy work; and "warmbloods," developed from crosses between hot bloods and cold bloods, often focusing on creating breeds for specific riding purposes, particularly in Europe.
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.
The Appaloosa is an American horse breed best known for its colorful spotted coat pattern. There is a wide range of body types within the breed, stemming from the influence of multiple breeds of horses throughout its history. Each horse's color pattern is genetically the result of various spotting patterns overlaid on top of one of several recognized base coat colors. The color pattern of the Appaloosa is of interest to those who study equine coat color genetics, as it and several other physical characteristics are linked to the leopard complex mutation (LP). Appaloosas are prone to develop equine recurrent uveitis and congenital stationary night blindness; the latter has been linked to the leopard complex.
The Darley Arabian was one of three dominant foundation sires of modern Thoroughbred horse racing bloodstock. The other two founders were the Godolphin Arabian and the Byerley Turk. This bay Arabian horse was bought in Aleppo, Syria, by Thomas Darley in 1704 and shipped to Aldby Park in England, as a present for his brother.
The Byerley Turk, also spelled Byerly Turk, was the earliest of three stallions that were the founders of the modern Thoroughbred horse racing bloodstock.
The Arabian or Arab horse is a breed of horse with historic roots 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 modern breeds. Although modern DNA cannot trace breed purity in the modern population beyond 200 years, there is archaeological evidence of horses in the Middle East with landrace characteristics that resemble modern Arabians dating back 3,500 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.
Purebreds are like cultivars of an animal species achieved through the process of selective breeding. When the lineage of a purebred animal is recorded, that animal is said to be pedigreed. Purebreds breed true-to-type which means the progeny of like-to-like purebred parents will carry the same phenotype, or observable characteristics of the parents. A group of like purebreds is called a pure-breeding line or strain.
A crossbreed is an organism with purebred parents of two different breeds, varieties, or populations. A domestic animal of unknown ancestry, where the breed status of only one parent or grandparent is known, may also be called a crossbreed though the term "mixed breed" is technically more accurate. Outcrossing is a type of crossbreeding used within a purebred breed to increase the genetic diversity within the breed, particularly when there is a need to avoid inbreeding.
A breed registry, also known as a herdbook, studbook or register, in animal husbandry, the hobby of animal fancy, is an official list of animals within a specific breed whose parents are known. Animals are usually registered by their breeders while they are young. The terms studbook and register are also used to refer to lists of male animals "standing at stud", that is, those animals actively breeding, as opposed to every known specimen of that breed. Such registries usually issue certificates for each recorded animal, called a pedigree, pedigreed animal documentation, or most commonly, an animal's "papers". Registration papers may consist of a simple certificate or a listing of ancestors in the animal's background, sometimes with a chart showing the lineage.
The Crabbet Arabian Stud, also known as the Crabbet Park Stud, was an English horse breeding farm that ran from 1878 to 1972. Its founder owners, husband and wife team Wilfrid Scawen Blunt and Lady Anne Blunt, decided while travelling in the Middle East to import some of the best Arabian horses to England and breed them there. They maintained the Sheykh Obeyd estate near Cairo to facilitate this. Their daughter Judith Blunt-Lytton, 16th Baroness Wentworth carried on the stud until her death. The stud was sold up in 1971, but its bloodlines continue to influence the breed worldwide in the 21st century.
Skowronek was an Arabian stallion foaled in 1908 or 1909. He was bred by Count Józef Potocki who owned the Antoniny Stud in Poland. He was imported to England as a young horse. Upon purchase by Lady Wentworth, Skowronek became a foundation stallion at Lady Wentworth's Crabbet Arabian Stud. He was most often crossed on mares who were daughters or granddaughters of the stallion Mesaoud, another foundation stallion for Crabbet, who had been bred by Ali Pasha Sherif and imported from Egypt to England by Lady Wentworth's parents, Wilfrid and Lady Anne Blunt.
Driftwood (1932–1960) was originally known as Speedy while he was a rodeo horse. Driftwood was known for siring rodeo and ranch horses.
Thoroughbred breeding theories, or racehorse 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.
The Thoroughbred is a horse breed developed for horse racing. Although the word thoroughbred is sometimes used to refer to any breed of purebred horse, it technically refers only to the Thoroughbred breed. Thoroughbreds are considered "hot-blooded" horses that are known for agility, speed, and spirit.
The Jersey Act was a regulation introduced to prevent the registration of most American-bred Thoroughbred horses in the British General Stud Book. It had its roots in the desire of British horse breeders to halt the influx of American-bred racehorses of possibly impure bloodlines during the early 20th century. Many American-bred horses were exported to Europe to race and retire to a breeding career after a number of U.S. states banned gambling, which depressed Thoroughbred racing—and thus breeding—in the United States. The loss of breeding records during the American Civil War and the late beginning of the registration of American Thoroughbreds led many in the British racing establishment to doubt that the American-bred horses were purebred.
The Andalusian, also known as the Pure Spanish Horse or PRE, is a horse breed from the Iberian Peninsula, where its ancestors have lived for thousands of years. The Andalusian has been recognized as a distinct breed since the 15th century, and its conformation has changed very little over the centuries. Throughout its history, it has been known for its prowess as a war horse, and was prized by the nobility. The breed was used as a tool of diplomacy by the Spanish government, and kings across Europe rode and owned Spanish horses. During the 19th century, warfare, disease and crossbreeding reduced herd numbers dramatically, and despite some recovery in the late 19th century, the trend continued into the early 20th century. Exports of Andalusians from Spain were restricted until the 1960s, but the breed has since spread throughout the world, despite their low population. In 2010, there were more than 185,000 registered Andalusians worldwide.
The Gidran, Gidrán, or Hungarian Anglo-Arab is a horse breed developed in Hungary from bloodstock that included the Arabian horse. All members of the breed are Chestnut. It is an endangered breed today, with only about 200 living representatives worldwide.
A part-Arabian, partbred Arabian or, less precisely, half-Arabian, is a horse with documented amounts of Arabian horse breeding but not a purebred. Because the Arabian is deemed to be a breed of purebred horse dating back many centuries, the modern breed registries recognized by the World Arabian Horse Organization generally have tightly closed stud books which exclude a horse from registration if it is found to contain any outside blood. However, Arabian breeding has also been used for centuries to add useful traits to countless other horse breeds. In the modern era, crossbreeding has been popular to combine the best traits of two different breeds, such as color, size, or ability to specialize in a particular equestrian discipline.
The Yeguada Militar de Jerez de la Frontera, known outside Spain as the Yeguada Militar, is a military Spanish stud farm headquartered in Andalusia, Spain, dedicated to horse breeding of purebred Andalusian horses and Arabian horses. Founded in 1847, it became the state military stud farm in 1893. In the 20th century, as need for cavalry horses declined, the stud's emphasis shifted to become a genetic reservoir to preserve the bloodlines of the Pure Spanish Horse and to continue to breed high quality Arabian horses, with stallions of both breeds being made available to private horse breeders to improve the horses of Spain. Today, there are two facilities located in the Jerez de la Frontera area, one primarily for stallions, the other for mares and foals, as well as multiple stallion depots across the country.
