The American Quarter Horse, or Quarter Horse, is an American breed of horse that excels at sprinting short distances. Its name came from its ability to outdistance other horse breeds in races of a quarter mile or less; some have been clocked at speeds up to 55 mph (88.5 km/h). The American Quarter Horse is the most popular breed in the United States today, and the American Quarter Horse Association is the largest breed registry in the world, with almost 3 million living American Quarter Horses registered in 2014.
The American Quarter Horse is well known both as a race horse and for its performance in rodeos, horse shows and as a working ranch horse. The compact body of the American Quarter Horse is well-suited to the intricate and speedy maneuvers required in reining, cutting, working cow horse, barrel racing, calf roping, and other western riding events, especially those involving live cattle. The American Quarter Horse is also shown in English disciplines, driving, and many other equestrian activities.
In the 17th century, colonists on the eastern seaboard of what today is the United States began to cross imported English Thoroughbred horses with assorted "native" horses such as the Chickasaw horse, which was a breed developed by Native American people from horses descended from Spain, developed from Iberian, Arabian and Barb stock brought to what is now the Southeastern United States by the Conquistadors.
One of the most famous of these early imports was Janus, a Thoroughbred who was the grandson of the Godolphin Arabian. He was foaled in 1746, and imported to colonial Virginia in 1756. The influence of Thoroughbreds like Janus contributed genes crucial to the development of the colonial "Quarter Horse". The breed is sometimes referred to as the "Famous American Quarter Running Horse". The resulting horse was small, hardy, and quick, and was used as a work horse during the week and a race horse on the weekends.
As flat racing became popular with the colonists, the Quarter Horse gained even more popularity as a sprinter over courses that, by necessity, were shorter than the classic racecourses of England, and were often no more than a straight stretch of road or flat piece of open land. When matched against a Thoroughbred, local sprinters often won. As the Thoroughbred breed became established in America, many colonial Quarter Horses were included in the original American stud books, starting a long association between the Thoroughbred breed and what would later become officially known as the "Quarter Horse", named after the mile (0.40 km) race distance at which it excelled. with some individuals being clocked at up to 55 mph.
In the 19th century, pioneers heading West needed a hardy, willing horse. On the Great Plains, settlers encountered horses that descended from the Spanish stock Hernán Cortés and other Conquistadors had introduced into the viceroyalty of New Spain, which today includes the Southwestern United States and Mexico. These horses of the west included herds of feral animals known as Mustangs, as well as horses domesticated by Native Americans, including the Comanche, Shoshoni and Nez Perce tribes. As the colonial Quarter Horse was crossed with these western horses, the pioneers found that the new crossbred had innate "cow sense", a natural instinct for working with cattle, making it popular with cattlemen on ranches.
Early foundation sires of Quarter horse type included Steel Dust, foaled 1843; Shiloh (or Old Shiloh), foaled 1844; Old Cold Deck (1862); Lock's Rondo, one of many "Rondo" horses, foaled in 1880; Old Billy--again, one of many "Billy" horses--foaled circa 1880; Traveler, a stallion of unknown breeding, known to have been in Texas by 1889; and Peter McCue, foaled 1895, registered as a Thoroughbred but of disputed pedigree.
The main duty of the ranch horse in the American West was working cattle. Even after the invention of the automobile, horses were still irreplaceable for handling livestock on the range. Thus, major Texas cattle ranches, such as the King Ranch, the 6666 (Four Sixes) Ranch, and the Waggoner Ranch played a significant role in the development of the modern Quarter Horse. The skills needed by cowboys and their horses became the foundation of the rodeo, a contest which began with informal competition between cowboys and expanded to become a major competitive event throughout the west. To this day, the Quarter Horse dominates the sport both in speed events and in competition that emphasizes the handling of live cattle.
However, sprint races were also popular weekend entertainment and racing became a source of economic gain for breeders as well. As a result, more Thoroughbred blood was added back into the developing American Quarter Horse breed. The American Quarter Horse also benefitted from the addition of Arabian, Morgan, and even Standardbred bloodlines.
In 1940, the American Quarter Horse Association (AQHA) was formed by a group of horsemen and ranchers from the southwestern United States dedicated to preserving the pedigrees of their ranch horses. The horse honored with the first registration number, P-1, was Wimpy, a descendant of the King Ranch foundation sire Old Sorrel. Other sires alive at the founding of the AQHA were given the earliest registration numbers Joe Reed P-3, Chief P-5, Oklahoma Star P-6, Cowboy P-12, and Waggoner's Rainy Day P-13. The Thoroughbred race horse Three Bars, alive in the early years of the AQHA, is recognized by the American Quarter Horse Hall of Fame as one of the significant foundation sires for the Quarter Horse breed. Other significant Thoroughbred sires seen in early AQHA pedigrees include Rocket Bar, Top Deck and Depth Charge.
Since the American Quarter Horse formally established itself as a breed, the AQHA stud book has remained open to additional Thoroughbred blood via a performance standard. An "Appendix" American Quarter Horse is a first generation cross between a registered Thoroughbred and an American Quarter Horse or a cross between a "numbered" American Quarter Horse and an "appendix" American Quarter Horse. The resulting offspring is registered in the "appendix" of the American Quarter Horse Association's studbook, hence the nickname. Horses listed in the appendix may be entered in competition, but offspring are not initially eligible for full AQHA registration. If the Appendix horse meets certain conformational criteria and is shown or raced successfully in sanctioned AQHA events, the horse can earn its way from the appendix into the permanent studbook, making its offspring eligible for AQHA registration.
Since Quarter Horse/Thoroughbred crosses continue to enter the official registry of the American Quarter Horse breed, this creates a continual gene flow from the Thoroughbred breed into the American Quarter Horse breed, which has altered many of the characteristics that typified the breed in the early years of its formation. Some breeders, who argue that the continued infusion of Thoroughbred bloodlines is beginning to compromise the integrity of the breed standard, favor the earlier style of horse and have created several separate organizations to promote and register "Foundation" Quarter Horses.
The American Quarter Horse is best known today as a show horse, race horse, reining and cutting horse, rodeo competitor, ranch horse, and all-around family horse. Quarter Horses compete well in rodeo events such as barrel racing, calf roping and team roping; and gymkhana or O-Mok-See. Other stock horse events such as cutting and reining are open to all breeds but also dominated by American Quarter Horse. Large purses allow top competitors to earn over a million dollars in these events.
The breed is not only well-suited for western riding and cattle work. Many race tracks offer Quarter Horses a wide assortment of pari-mutuel horse racing with purses in the millions. Quarter Horses have also been trained to compete in dressage and can be good jumpers. They are also used for recreational trail riding and in mounted police units.
The American Quarter Horse has also been exported worldwide. European nations such as Germany and Italy have imported large numbers of Quarter Horses. Next to the American Quarter Horse Association (which also encompasses Quarter Horses from Canada), the second largest registry of Quarter Horses is in Brazil, followed by Australia. With the internationalization of the discipline of reining and its acceptance as one of the official seven events of the World Equestrian Games, there is a growing international interest in Quarter Horses. Countries like Japan, Switzerland and Israel that did not have traditional stock horse industries have begun to compete with American Quarter Horses in their own nations and internationally. The American Quarter Horse is the most popular breed in the United States today, and the American Quarter Horse Association is the largest breed registry in the world, with over 5 million American Quarter Horses registered worldwide.
The Quarter Horse has a small, short, refined head with a straight profile, and a strong, well-muscled body, featuring a broad chest and powerful, rounded hindquarters. They usually stand between 14 and 16 hands (56 and 64 inches, 142 and 163 cm) high, although some Halter-type and English hunter-type horses may grow as tall as 17 hands (68 inches, 173 cm).
There are two main body types: the stock type and the hunter or racing type. The stock horse type is shorter, more compact, stocky and well-muscled, yet agile. The racing and hunter type Quarter Horses are somewhat taller and smoother muscled than the stock type, more closely resembling the Thoroughbred.
Quarter Horses come in nearly all colors. The most common color is sorrel, a brownish red, part of the color group called chestnut by most other breed registries. Other recognized colors include bay, black, brown, buckskin, palomino, gray, dun, red dun, grullo (also occasionally referred to as blue dun), red roan, blue roan, bay roan, perlino, cremello, and white. In the past, spotted color patterns were excluded, but now with the advent of DNA testing to verify parentage, the registry accepts all colors as long as both parents are registered.
A stock horse is a horse of a type that is well suited for working with livestock, particularly cattle. Reining and cutting horses are smaller in stature, with quick, agile movements and very powerful hindquarters. Western pleasure show horses are often slightly taller, with slower movements, smoother gaits, and a somewhat more level topline - though still featuring the powerful hindquarters characteristic of the Quarter Horse.
Horses shown in-hand in Halter competition are larger yet, with a very heavily muscled appearance, while retaining small heads with wide jowls and refined muzzles. There is controversy amongst owners, breeder and veterinarians regarding the health effects of the extreme muscle mass that is currently fashionable in the specialized halter horse, which typically is 15.2 to 16 hands (62 to 64 inches, 157 to 163 cm) and weighs in at over 1,200 pounds (540 kg) when fitted for halter competition. Not only are there concerns about the weight to frame ratio on the horse's skeletal system, but the massive build is also linked to hyperkalemic periodic paralysis (HYPP) in descendants of the stallion Impressive (see Genetic diseases below).
Quarter Horse race horses are bred to sprint short distances ranging from 220 to 870 yards. Thus, they have long legs and are leaner than their stock type counterparts, but are still characterized by muscular hindquarters and powerful legs. Quarter Horses race primarily against other Quarter Horses, and their sprinting ability has earned them the nickname, "the world's fastest athlete." The show hunter type is slimmer, even more closely resembling a Thoroughbred, usually reflecting a higher percentage of appendix breeding. They are shown in hunter/jumper classes at both breed shows and in open USEF-rated horse show competition.
There are several genetic diseases of concern to Quarter Horse breeders:
