Anglo-Arabian Horse

The Anglo-Arabian or Anglo-Arab is a crossbred, part-Arabian horse that now also has its own status as a horse breed. It is a Thoroughbred (thus, the prefix "Anglo") crossed with an Arabian. The cross can be made between a Thoroughbred stallion and an Arabian mare, or vice versa. It can also be a cross between either an Anglo-Arab and a Thoroughbred or, alternatively, an Anglo-Arab and an Arabian. Another permitted cross is between two Anglo-Arabians. No matter the cross, a horse must have a minimum 12.5% of Arabian blood to be considered an Anglo-Arabian.

France is one of the greatest producers of Anglo-Arabians. The French Anglo-Arab traces back to two stallions: the Arabian stud Massoud and Aslam, a "Turkish" horse, probably of the now-extinct Turkoman or "Turkmene" breed. These Syrian imports were then crossed with a trio of Thoroughbreds, specifically, the Comus Mare, the Selim Mare, and Daer. Some years later, three of their daughters — Clovis, Danae, and Delphine — formed the foundation of the French Anglo-Arabian breeding program. The program's primary Anglo-Arab breeding farm, Pompadour National Anglo-Arab Stud, is located in Arnac-Pompadour, a commune of central France's Corrèze department, home to the famous Château de Pompadour. In addition, the area serves as the French National Stud's headquarters. The Anglo-Arabian possesses one of France's oldest studbooks, and the Selle Français, the country's leading sport horse, still bears the stamp of significant Anglo-Arab influence.

In the past, the Anglo-Arab has been used for military purposes. However, at present, its most prominent occupation is that of a general riding or sport horse. The breed does well in eventing, due to its stamina, speed, and jumping ability. In the United States, the Anglo-Arabian is considered a "part-bred" Arabian and, consequently, is registered within a separate section of the Arabian Horse Association.

Breed Characteristics

As a result of different crosses that can produce an Anglo-Arabian, the size and appearance is noticeably variable. However, on average, an Anglo-Arabian is a bit taller than the average Arabian and of somewhat less refined type. The largest horses are usually produced by breeding a Thoroughbred mare to an Arabian stallion. The best examples of this breed inherit the refinement, good bone, and endurance of the Arabian, as well as the speed and scope of the Thoroughbred.

Anglo-Arabians average 15.2–16.3  hands (62–67 inches, 157–170 cm) high. The most common colors are chestnut, bay (sometimes called "brown") or gray. The breed ideal is for a horse to have conformation that more strongly resembles the Arabian, though they should not look entirely like either a Thoroughbred or an Arabian. They have a long neck, prominent withers, a compact and strong body (sturdier than the Thoroughbred), a deep chest, and solid bone. Anglo-Arabians should have small, fine heads, similar to an Arabian, but they should not be overly "dished" in profile.

Andravida Horse

The Andravida or Eleia Horse is a light draft breed found in the region of Ilia in Greece. It owes its development to the crossing of Anglo-Norman with local breeds with additional crosses of Nonius stallions after 1920. The breed is close to extinction and its stud book was only established in 1995.

The members of the breed are predominantly brown, bay, chestnut, red roan, black and occasionally grey, though, this tends to be a rare phenomenon. The head is rectangular in shape - quite unremarkable and plain with long ears and a straight profile. The chest is broad and heavy-set with thick muscles; the back is slightly dipped; the shoulders should be well-sloped and the croup only gently so. The horse's legs should be free of excess hair, very strong and thick with good bone. The breed's temperament is described as willing but strong. The breed is of moderate height ranging between 14 and 16 hands high with the average being at around 15 hands.

The breed is believed to trace to the cavalry horses of Ancient Greece; in the fourth century BC used by the Athenian Army. In peace times, the breed was used to transport goods from remote villages and for riding. Beginning in the 13th centyuy, Arabian blood was introduced to create the lighter strain of this breed. In the 20th century, Anglo-Norman blood was added, but numbers went into decline. The breed was saved from extinction in the early 1990s, when Andravida's Selle Francais stallion Calin de Nanteuil, renamed Pegasus, covered some mares, resulting in 50 healthy foals that went to breeders throughout western Greece. Despite this, however, the breed's numbers are still very low, and they are rarely, if at all, found outside of Ilia, where they are bred almost exclusively.

American Warmblood Horse

The American Warmblood is a horse of warmblood type, intended primarily for the traditional sport horse disciplines of (dressage, show jumping, eventing) and combined driving.

Characteristics

The American Warmblood is usually between 15 and 17 hands high and all colors are accepted, though the solid colors are the most common. Horses of nearly all bloodlines are eligible for registration as American Warmbloods, as long as they are of a sport horse or warmblood type, and are able to meet the appropriate studbook selection or performance criteria.

The emphasis is on the quality of each individual horse, for both registration and breeding approval. Horses which are 100% hot or cold blooded are not eligible for registration, but may be "Nominated" if they are able to meet the registry's standards (this would include draft horses, Arabians, and Thoroughbreds).

Breeding stock must be approved for breeding through studbook inspection, which requires mares and stallions to meet even more stringent inspection and/or performance criteria.

Horses which fail to meet these criteria may still be issued recording papers, but are not considered registered American Warmbloods.

Breed history

There are two registries in the United States which recognize American Warmbloods - the American Warmblood Society and the American Warmblood Registry, both of which are recognized by the World Breeding Federation for Sport Horses (WBFSH).

The American Warmblood is more of a "type" than a "breed". Like most of the European warmbloods, the American Warmblood has an "open" book. There is more emphasis on producing quality sport horses, rather than the preservation of any particular bloodlines, which allows for much diversity in the bloodlines of American Warmbloods.

The American Warmblood has been influenced by the European warmbloods, the Thoroughbred and the Arabian, as well as some draft horse breeds.

American Saddlebred Horse

The American Saddlebred is a horse breed from the United States. Descended from riding-type horses bred at the time of the American Revolution, the American Saddlebred includes the Narragansett Pacer, Canadian Pacer, Morgan and Thoroughbred among its ancestors. Developed into its modern type in Kentucky, it was once known as the "Kentucky Saddler", and used extensively as an officer's mount in the American Civil War. In 1891, a breed registry was formed in the United States. Throughout the 20th century, the breed's popularity continued to grow in the United States, and exports began to South Africa and Great Britain. Since the formation of the US registry, almost 250,000 American Saddlebreds have been registered, and can now be found in countries around the world, with separate breed registries established in Great Britain, Australia, continental Europe, and southern Africa.

Averaging 15 to 16 hands (60 to 64 inches, 152 to 163 cm) in height Saddlebreds are known for their sense of presence and style, as well as for their spirited, yet gentle, temperament. They may be of any color, including pinto patterns, which have been acknowledged in the breed since the late 1800s. They are considered a gaited breed, as some Saddlebreds are bred and trained to perform four-beat ambling gaits, one being a "slow gait" that historically was one of three possible ambling patterns, and the much faster rack. The breed does have a hereditary predisposition to lordosis, a curvature of the spine, as well as occupational predispositions to upper respiratory and lameness issues.

Since the mid-1800s, the breed has played a prominent part in the US horse show industry, and is called the "peacock of the horse world". They have attracted the attention of numerous celebrities, who have become breeders and exhibitors, and purebred and partbred American Saddlebreds have appeared in several films, especially during the Golden Age of Hollywood. Saddlebreds are mainly known for their performance in the show ring, but can also be seen in competition in several other English riding disciplines and combined driving, as well as being used as a pleasure riding horse.

Characteristics

American Saddlebreds stand 15 to 17 hands (60 to 68 inches, 152 to 173 cm) high, averaging 15 to 16 hands (60 to 64 inches, 152 to 163 cm), and weigh between 1,000 and 1,200 pounds (450 and 540 kg). Members of the breed have well-shaped heads with a straight profile, long, slim, arched necks, well-defined withers, sloping shoulders, correct leg conformation, and strong level backs with well-sprung ribs. The croup is level with a high-carried tail. Enthusiasts consider them to be spirited, yet gentle, animals. Any color is acceptable, but most common are chestnut, bay, brown and black. Some are gray, roan, palomino and pinto. The first-known pinto Saddlebred was a stallion foaled in 1882. In 1884 and 1891, two additional pintos, both mares, were foaled. These three horses were recorded as "spotted", but many other pinto Saddlebreds with minimal markings were recorded only by their base color, without making note of their markings. This practice continued into the 1930s, at which time breeders came to be more accepting of "colored" horses and began recording markings and registering horses as pinto. The Saddlebred has been called the "world's most beautiful horse" by admirers, and is known as the "peacock of the horse world". The United States Equestrian Federation (USEF) describes the Saddlebred as follows: "He carries himself with an attitude that is elusive of description—some call it "class", presence, quality, style, or charm. This superior air distinguishes his every movement."

Saddlebreds are popularly known as show horses, with horses being shown saddle seat in both three-gaited and five-gaited classes. The former are the three common gaits seen in most breeds, the walk, trot and canter. The latter includes the three regular gaits, plus two four-beat ambling gaits known as the slow gait and the rack. The slow gait today is a four-beat gait in which the lateral pairs of legs leave the ground together, but strike the ground at different times, the hind foot connecting slightly before the forefoot. In the show ring, the gait should be performed with restraint and precision. The rack is also a four-beat gait, but with equal intervals between each footfall, making it a smooth gait to ride. In the show ring, the gait is performed with speed and action, appearing unrestrained. Historically, the slow gait could be either a running walk, the stepping pace, or the fox trot, however, the modern five-gaited Saddlebred usually performs the stepping pace.

Lordosis, also known as swayback, low back or soft back, has been found to have a hereditary basis in Saddlebreds and a recessive mode of inheritance. The precise mutation has not yet been located, but researchers believe it to be somewhere on horse chromosome 20. Researching this condition may help more than just the Saddlebred breed as it may "serve as a model for investigating congenital skeletal deformities in horses and other species." Due to the head position common in the show ring, Saddlebreds can have impairments to the upper respiratory system, while the shoeing and movement required of the horses can cause leg and hoof injuries and increased lameness. A swayback is penalized as a fault at shows, in addition to other conformation flaws.

History

The Saddlebred has origins in the Galloway and Hobby horses of the British Isles, animals sometimes called palfreys, which had ambling gaits and were brought to the United States by early settlers. These animals were further refined in America to become a now-extinct breed called the Narragansett Pacer,  a riding and driving breed known for its ambling and pacing gaits. When colonists imported Thoroughbreds to America, beginning in 1706, they were crossed with the Narragansett Pacer, which, combined with massive exports, ultimately led to the extinction of the Narragansett as a purebred breed. To preserve important bloodlines, Canadian Pacers were introduced instead. By the time of the American Revolution, a distinct type of riding horse had developed with the size and quality of the Thoroughbred, but the ambling gaits and stamina of the Pacer breeds. This animal was called the American Horse. Its existence was first documented in a 1776 letter when an American diplomat wrote to the Continental Congress asking for one to be sent to France as a gift for Marie Antoinette.

19th century

Other breeds which played a role in the development of the Saddlebred in the 1800s include the Morgan, Standardbred and Hackney. The Canadian Pacer had a particularly significant impact. The breed, originally of French origin, was also influential in the development of the Standardbred and Tennessee Walking Horse. The most influential Canadian Pacer on Saddlebred lines was Tom Hall, a blue roan stallion foaled in 1806. After being imported to the United States from Canada, he was registered as an American Saddlebred and became the foundation stallion of several Saddlebred lines.

The American Horse was further refined in Kentucky, where the addition of more Thoroughbred blood created a taller and better-looking horse that became known as the Kentucky Saddler. There were originally seventeen foundation stallions listed by the breed registry, but by 1908 the registry decided to list only one and the remainder were identified as "Noted Deceased Sires." Today, two foundation sires of the breed are recognized, both Thoroughbred crosses. The first was Denmark, son of an imported Thoroughbred, who for many years was the only recognized foundation stallion. His son, Gaines' Denmark, was in the pedigrees of over 60 percent of the horses registered in the first three volumes of the breed's studbook. A second foundation sire was recognized in 1991, Harrison Chief. This sire was a descendent of the Thoroughbred Messenger, who is also considered a foundation stallion for the Standardbred breed.

During the American Civil War, American Saddlebreds were commonly used by the military, and known for their bravery and endurance. Many officers used them as mounts, and included in their numbers are General Lee's Traveller, General Grant's Cincinnati, General Sherman's Lexington, and General Jackson's Little Sorrell. Other generals who used them during the conflict include John Hunt Morgan and Basil W. Duke during his time with Morgan's Raiders. Kentucky Saddlers were used during brutal marches with the latter group, and the historical record suggests that they held up better than horses of other breeds.

The American Saddlebred Horse Association was formed in 1891, then called the National Saddle Horse Breeders Association (NSHBA). Private individuals had produced studbooks for other breeds, such as the Morgan, as early as 1857, but the NSHBA was the first national association for an American-developed breed of horse. A member of Morgan's Raiders, General John Breckinridge Castleman, was instrumental in forming the NSHBA. In 1899, the organization name was changed to the American Saddle Horse Breeders Association, clarifying the breed's name as the "American Saddle Horse," not simply "Saddle Horse."

20th century to present

After World War I, the American Saddlebred began to be exported to South Africa, and it is now the most popular non-racing breed in that country. Saddlebred horse show standards continued to evolve through the 1920s, as the popularity of the breed grew. The Saddlebred industry slowed during World War II, but began to grow again post-war, with Mexico, Missouri earning the title "Saddle Horse Capital of the World". Exports continued, and though attempts to begin a South African breed registry had started in 1935, it was not until 1949 that the Saddle Horse Breeders' Society of South Africa was formed. The 1950s saw continued growth of the Saddlebred breed, and The Lemon Drop Kid, a fine harness horse, became the first, and only, Saddlebred to appear on the cover of Sports Illustrated. In the late 1950s, the Saddle Horse Capital became centered in Shelby County, Kentucky, largely due to the success of breeders Charles and Helen Crabtree, the latter a renowned equitation coach. Although individual Saddlebreds had been exported to Great Britain throughout the breed's history, the first breeding groups were transported there in 1966. For the next three decades, enthusiasts worked to establish a breeding and showing platform for the breed in the UK.

In 1980, the name of the American Saddle Horse Breeder's Association was changed to the American Saddlebred Horse Association (ASHA), membership was opened to non-breeders, and the group began to focus on breed promotion. In 1985, the ASHA became the first breed registry to have their headquarters at the Kentucky Horse Park in Lexington, Kentucky. A decade later, in 1995, the United Saddlebred Association – UK was formed to register Saddlebreds in Great Britain, and acts as the British affiliate of the ASHA. Since the founding of the American registry, almost 250,000 horses have been accepted, with almost 3,000 new foals registered annually. It is the oldest still-functioning breed registry in the US. Most common in the eastern US, the breed is also found throughout North America, Europe, Australia, and in South Africa.

Located at the Kentucky Horse Park is the American Saddlebred Museum, which curates a large collection of Saddlebred-related items and artwork, as well as a 2,500-volume library of breed-related works. There are two magazines which focus on the American Saddlebred: The National Horseman and Saddle and Bridle.

Show ring history

As a show horse, Saddlebreds were exhibited in Kentucky as early as 1816, and were a prominent part of the first national horse show in the United States, held at the St. Louis Fair in 1856. The Kentucky State Fair began running a World Championship show in 1917, offering a $10,000 prize for the champion five-gaited horse. Also in 1917, the American Horse Shows Association, now the United States Equestrian Federation, formed and began to standardize show formats and rules. In 1957, the American Saddlebred Pleasure Horse Association was formed to regulate English pleasure classes. Today, the most prestigious award in the breed industry is the American Saddlebred "Triple Crown": Winning the five-gaited championships at the Lexington Junior League horse show, the Kentucky State Fair World's Championship Horse Show, and American Royal horse show; a feat that has only been accomplished by six horses.

The breed's show history also paralleled major historical developments. Heavyweight boxing champion Joe Louis, who owned and exhibited Saddlebreds into the 1940s, organized the first "All-Negro" horse show in Utica, Michigan, allowing greater opportunities for African-American people to exhibit horses at a time when there was significant racial segregation in the United States. Gas shortages in the 1970s and 1980s put pressure on the recreational dollar, and saw the growth of single breed shows at the expense of the multi-breed traditional horse show. At the beginning of the 21st century, the number of women showing Saddlebreds increased, with female competitors winning several world championships.

Uses

Today, the Saddlebred is exhibited in the United States in multiple divisions, including assorted in-hand classes; ridden in saddle seat classes for three- and five-gaited horses in both Park and pleasure classes, hunter country pleasure, and western pleasure; plus pleasure driving, fine harness, roadster harness classes. In five-gaited competition, they are shown with a full tail, often augmented with an artificial switch, and a full mane. Three-gaited horses are shown with a shaved off "roached" mane and with the hair at the top of their tails, an area called the dock, trimmed short. While use of a set tail in certain types of competition was common, today, tailsets are generally not allowed on the show grounds, except for horses in the Park Pleasure division, and horses with unset tails are not penalized in any division. Gingering is prohibited.

Outside of breed-specific shows, the Saddlebred is also promoted as suitable for competitive trail riding, endurance riding, dressage, combined driving, eventing, and show jumping. Some Saddlebreds are also suitable for fox hunting, cutting and roping. Because they are so closely affiliated with their traditional show ring competition, they are sometimes mistaken for warmbloods or Thoroughbred crosses when participating in other equine events. They are also suitable family horses used for trail and pleasure riding and ranch work.

Film and celebrity affiliation

Many film and television horses of the Golden Age of Hollywood were also Saddlebreds, including the horses used in lead roles in My Friend Flicka, National Velvet, Fury and one version of Black Beauty. A half-Saddlebred played the lead role in the TV series Mr. Ed, and a Saddlebred was used in a prominent role in Giant. In the 1990s, William Shatner, an actor and Saddlebred breeder, rode one of his own horses, a mare named Great Belles of Fire, in his role as James T. Kirk in Star Trek Generations. Numerous other celebrities have been owners and exhibitors of the breed, including Clark Gable, Will Rogers, Joe Louis, and Carson Kressley.

American Quarter Horse

The American 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 individuals 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 more than 5 million American Quarter Horses registered.

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.

Breed history

Colonial era

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 distance at which it excelled, with some individuals being clocked at up to 55 mph.

Westward expansion

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.

Development as a distinct breed

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.

"Appendix" and "Foundation" horses

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, have created several separate organizations to promote and register "Foundation" Quarter Horses.

Quarter Horses today

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 some of 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.[citation needed] 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.

Breed characteristics

The modern 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.

Stock type

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.

Halter type

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 HYPP.

Racing and hunter type

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.

Colors

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.

Genetic diseases

There are several genetic diseases of concern to Quarter Horse breeders:


    Hyperkalemic periodic paralysis (HYPP), which is caused by an autosomal dominant gene linked to the stallion Impressive. It is characterized by uncontrollable muscle twitching and substantial muscle weakness or paralysis among affected horses. Because it is a dominant gene, only one parent has to have the gene for it to be transmitted to offspring. There is a DNA test for HYPP, which is required by the AQHA. Since 2007, the AQHA bars registration of horses who possess the homozygous form (H/H) of the gene, and though heterozygous (H/N) horses are still eligible for registration, altering that status is currently being discussed. Additionally all Quarter Horses born 2007 or later that are confirmed to be descendants of Impressive must carry a note about the risks of HYPP on their registration papers. Due to HYPP, the halter classes are undergoing significant changes. Halter classes are dominated by the Impressive bloodline. Impressive, a very prolific halter horse, brought to the stock breeds the muscle mass that is popular in halter competition today. This muscle mass is linked to HYPP, and as the condition is reduced within the breed, the style of horse in halter classes is also likely to change. Already there have been rule changes, including the creation of a "Performance Halter class" in which a horse must possess a Register of Merit in performance or racing before it can compete.

    Malignant hyperthermia. A causative mutated allele, ryanodine receptor 1 gene (RyR1) at nucleotide C7360G, generating a R2454G amino acid substitution. has been identified in the American Quarter Horse and breeds with Quarter Horse ancestry, inherited as an autosomal dominant It can be caused by overwork, anesthesia, or stress.

    Hereditary Equine Regional Dermal Asthenia (HERDA), also known as hyperelastosis cutis (HC). This is caused by an autosomal recessive gene, and thus, unlike HYPP, HERDA can only be transmitted if both parents carry the gene. When a horse has this disease, there is a collagen defect that results in the layers of skin not being held firmly together. Thus, when the horse is ridden under saddle or suffers trauma to the skin, the outer layer often splits or separates from the deeper layer, or it can tear off completely. It rarely heals without disfiguring scars. Sunburn can also be a concern. In dramatic cases, the skin can split along the back and even roll down the sides, with the horse literally being skinned alive. Most horses with HERDA are euthanized for humane reasons between the age of two and four years. The very hotly debated and controversial theory, put forth by researchers at Cornell University and Mississippi State University is that the sire line of the great foundation stallion Poco Bueno is implicated as the origin of the disease. As of May 9, 2007, Researchers working independently at Cornell University and at the University of California, Davis announced that a DNA test for HERDA has been developed. Over 1,500 horses were tested during the development phase of the test, which is now available to the general public through both institutions.

    Glycogen Branching Enzyme Deficiency (GBED) is a genetic disease where the horse is lacking an enzyme necessary for storing glycogen, the horse's heart muscle and skeletal muscles cannot function, leading to rapid death. The disease occurs in foals who are homozygous for the lethal GBED allele, meaning both parents carry one copy of the gene. The stallion King P-234 has been linked to this disease. There is a DNA blood test for this gene.

    Equine polysaccharide storage myopathy, also called EPSM or PSSM, is a metabolic muscular condition in horses that causes tying up, and is also related to a glycogen storage disorder. While also seen in some draft horse breeds, PSSM has been traced to three specific but undisclosed bloodlines in Quarter Horses, with an autosomal recessive inheritance pattern. 48% of Quarter Horses with symptoms of neuromuscular disease have PSSM. To some extent it can be diet controlled with specialized low-starch diets, but genetic testing is advised before breeding, as the condition exists at a subclinical level in approximately 6% of the general Quarter Horse population.

    Lethal White Syndrome. Although "cropout" Quarter Horses with Paint markings were not allowed to be registered for many years, the gene for such markings is a recessive and continued to periodically appear in Quarter Horse foals. Thus, it is believed that some Quarter Horses may carry the gene for Lethal White Syndrome. There is a DNA test for this condition.

American Paint Horse

The American Paint Horse is a breed of horse that combines both the conformational characteristics of a western stock horse with a pinto spotting pattern of white and dark coat colors. Developed from a base of spotted horses with Quarter Horse and Thoroughbred bloodlines, the American Paint Horse Association (APHA) breed registry is now one of the fastest-growing in North America. The registry allows some non-spotted animals to be registered as "Solid Paint Bred" and considers the American Paint Horse to be a horse breed with distinct characteristics, not merely a color breed.

Registration

The American Paint Horse's combination of color and conformation has made the American Paint Horse Association (APHA) the second-largest breed registry in the United States. While the colorful coat pattern is essential to the identity of the breed, American Paint Horses have strict bloodline requirements and a distinctive stock-horse body type. To be eligible for registry, a Paint's sire and dam must be registered with the American Paint Horse Association, the American Quarter Horse Association, or the Jockey Club (Thoroughbreds). At least one of the parents must be a registered American Paint Horse. There are two categories of registration, regular, for horses with color, and solid Paint-bred, for those without color.

Regular APHA registration

In addition to bloodlines, to be eligible for the Regular Registry of the American Paint Horse Association (APHA), the horse must also exhibit a "natural paint marking", meaning either a predominant hair coat color with at least one contrasting area of solid white hair of the required size with some underlying unpigmented skin present on the horse at the time of its birth. Or, in the case of a predominantly white hair coat, at least one contrasting area of the required size of colored hair with some underlying pigmented skin present on the horse. Natural Paint markings usually must cover more than two inches and be located in certain designated areas of the body.

Solid Paint-Bred

Solid colored offspring of two registered Paint parents, called "Solid Paint-Breds" or "Breeding Stock Paints," are also eligible for registration, with certain restrictions. They are able to participate in some recognized Paint breed shows, and there are alternative programs offered, and many incentive programs within the registry are available to Solid Paint-bred horses. If a solid-colored horse is bred to a regular registry Paint horse, it is possible to produce a spotted foal. In some cases, such as the recessive sabino patterns, described below, even a solid colored horse may still carry genes for color. However, in the case of the dominant tobiano pattern, a Breeding Stock Paint will not carry these color genes, though it may retain other desirable traits.

Color

Each Paint Horse has a particular combination of white and another color of the equine spectrum. Most common are horses with white spots combined with black, bay, brown, and chestnut or sorrel. Less common are horses with spot colors influenced by dilution genes such as palomino, buckskin, cremello, perlino, pearl or "Barlink factor", and champagne, various shades of roan, or various shades of dun, including grullo. Paints may also carry the gray gene and have spots that eventually fade to white hair, though retaining pigmented skin underneath the areas that were once dark.

Spots can be any shape or size, except leopard complex patterning, which is characteristic of the Appaloosa, and located virtually anywhere on the Paint's body. Although Paints come in a variety of colors with different markings and different underlying genetics, these are grouped into only four defined coat patterns: overo (includes frame, splash and sabino), tobiano and tovero and solid.

Breeding Stock Paints can sometimes showcase small color traits, particularly if they carry sabino genetics. Such traits include blue eyes, pink skin on lips and nostrils, roan spots, and minimal roaning.

Terms for color patterns defined

    Tobiano: The most common spotting pattern, characterized by rounded markings with white legs and white across the back between the withers and the dock of the tail, usually arranged in a roughly vertical pattern and more white than dark, with the head usually dark and with markings like that of a normal horse. i.e. star, snip, strip, or blaze.
    Overo: A group of spotting patterns characterized by sharp, irregular markings with a horizontal orientation, usually more dark than white, though the face is usually white, sometimes with blue eyes. The white rarely crosses the back, and the lower legs are normally dark. The APHA recognizes three overo patterns:
        Frame: The most familiar overo pattern, the gene for frame has been genetically mapped and in the homozygous form, results in Lethal White Syndrome (LWS). Visually identified frames have no health defects connected to their color, and are characterized by ragged, sharp white patches on the sides of the body, leaving a "frame" of non-white color that typically includes the topline.
        Sabino: Often confused with roan or rabicano, sabino is a slight spotting pattern characterized by high white on legs, belly spots, white markings on the face extending past the eyes and/or patches of roaning patterns standing alone or on the edges of white markings.
        Splashed white: The least common spotting pattern, splashed whites typically have blue eyes and crisp, smooth, blocky white markings that almost always include the head and legs. The tail is often white or white-tipped, and body markings originate under the belly and extend "upwards".
    Tovero: spotting pattern that is a mix of tobiano and overo coloration, such as blue eyes on a dark head.
    Solid: A horse otherwise eligible for registration as a Paint that does not have any white that constitutes a recognized spotting pattern.
    "Color": An informal term meaning that the horse has a spotting pattern. (The opposite of "Solid.")
    "Chrome": An informal term of approval used in some geographic regions to describe a particularly flashy spotting pattern.

Paint or Pinto?

The terms "paint" and "pinto" are sometimes both used to describe spotted horses, but in modern use there is a clear difference between the two terms. A pinto differs from a Paint solely due to bloodlines. A pinto may be of any breed or combination of breeds, though some Pinto registries may have additional restrictions. (Some do not register draft horses or mules, for example.) For a horse to be registered as an American Paint Horse however, it must have registered American Quarter Horse, American Paint Horse, or Thoroughbred parents. Therefore, all Paint horses (except for the small number of "solids" allowed into the Paint registry) could be registered as pintos, but not all pintos qualify to be registered as Paints.

History

The American Paint Horse shares a common ancestry with the American Quarter Horse and the Thoroughbred. A registered Paint horse should conform to the same "stock horse" body type desired in Quarter Horses: a muscular animal that is heavy but not too tall, with a low center of gravity for maneuverability, and powerful hindquarters suitable for rapid acceleration and sprinting.

When the American Quarter Horse Association emerged in 1940 to preserve horses of the "stock" type, it excluded those with pinto coat patterns and "crop out" horses, those born with white body spots or white above the knees and hocks. Undeterred, fans of colorful stock horses formed a variety of organizations to preserve and promote Paint horses. In 1965 some of these groups merged to form the American Paint Horse Association.

Genetic Problems

One medical issue associated with the breed is the genetic disease lethal white syndrome (LWS). Also called Overo Lethal White Syndrome (OLWS) or, less often, White Foal Syndrome (WFS), it is linked to a recessive gene associated with the frame overo pattern. Horses that are heterozygous carriers of the gene do not develop the condition and are physically healthy. However, when a foal is born that is homozygous for the LWS gene, it should be humanely euthanized shortly after birth, or else will die within a few days from complications involving an underdeveloped intestinal tract. A DNA test is available for LWS so that horses who are carriers of this gene are not bred to one another. Horses can carry the LWS gene and not visibly exhibit overo coloring; cases have appeared in the offspring of both tobiano and solid-colored parents, though all cases to date are horses that had overo ancestors. LWS is also not unique to Paint Horses; it can occur in any equine breed where the frame overo coat pattern is found.

Due to the heavy influx of American Quarter Horse breeding, some Paints may also carry genetic disorders such as Hyperkalemic Periodic Paralysis (HYPP), Hereditary Equine Regional Dermal Asthenia (HERDA), Equine polysaccharide storage myopathy (called PSSM - polysaccharide storage myopathy - in Paints, Quarter Horses and Appaloosas), Malignant hyperthermia (MH) and Glycogen Branching Enzyme Deficiency (GBED). The influence of Thoroughbred breeding puts some bloodlines at higher risk for Wobbler's syndrome.

American Indian Horse

The American Indian Horse is defined by its breed registry as a horse that may carry the ancestry of the Spanish Barb, Arabian, Mustang, or "Foundation" Appaloosa.

It is the descendant of horses originally brought to the Americas by the Spanish and obtained by Native American people. The registry was created in 1961 when some breeders of Colonial Spanish Horse bloodlines considered the Spanish Mustang breeders to be departing from the original "Indian horse" phenotype. The organization was started "for the purpose of collecting, recording and preserving the pedigrees of American Indian Horses." The registry also allows the "hybrids and descendants" of the original Spanish Colonial Horse to be registered. Horses registered with other breed registries to be double-registered with this organization if the horses meet the conformation requirements.

Characteristics

American Indian Horses generally range in height from 13 to 16 hands (52 to 64 inches, 132 to 163 cm) and weigh between 700 to 1,000 pounds (320 to 450 kg). They may be any coat color and both pinto and leopard spotting patterns are common. They are hardy, surefooted, and no draft horse breeding is allowed. Some may be gaited.

There are five registration categories:

    Class O ("Original") horses have a recorded pedigree chart that can be traced to either one of the Mustang registries or "various American Indian tribes and families."    Class A horses have unknown bloodlines, but meet the breed standard. This category can include grade horses or horses of unknown bloodlines. Horses adopted from the Bureau of Land Management (BLM) are Class A horses.
    Class AA horses are over four years old, have been inspected for their conformation and "are at least half-O in breeding or are of exceptional O type." Some horses adopted from the Bureau of Land Management (BLM) can qualify for this status.
    Class M ("Modern") horses are of "modern" type. They may have registered parents from breeds that the American Indian Horse Registry considers to be descended from the original type, including American Quarter Horses, Appaloosas, American Paint Horses, and horses registered with various color breed registries such as those for pinto or palomino horses.
    Class P ("Pony") registration is for ponies that have the proper type characteristics. They might have pedigreed breeding such as the Galiceno or Pony of the Americas, or could be of unknown ancestry.

Uses

American Indian Horses are ridden in western-style classes in horse show and Gymkhana speed events. They are also used for pleasure riding and trail riding.
