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.
Registries which implement studbook selection differ from registries which require only two parents of the proper pedigree or registration status. For example, a horse foal with two Thoroughbred parents is almost certainly a Thoroughbred, but a foal with two Oldenburg parents may not be accepted through studbook selection to be an Oldenburg.
The pattern of studbook selection varies from nation to nation and registry to registry, but among horse registries, particularly warmblood registries, the general outline includes an inspection of foals before formal registration, evaluation of conformation and movement of broodmares, and evaluation of the conformation, movement, health, and performance ability of stallions. Decisions about which mares and stallions are suitable breeding stock are made by elected breed judges, who strive for objectivity and transparency.
Foals are usually presented at a local mare and foal show by their dam's side. If the foal's sire and dam are in the studbook, and he generally fits into the breeding goal, he receives his papers and a brand on the left thigh. The brand identifies his registry. Although foals are not usually scored, some registries award "Premium" status to high-quality foals, and colts may be deemed stallion prospects by the judge(s).
Foal inspections are also used to determine whether or not a stallion is producing offspring that fit the breeding goal.
The first method of evaluating breeding stock in many warmblood registries is the studbook inspection. Fillies may be evaluated at age 3 at a local mare and foal show, and colts may be evaluated at age 2 at the Körung, which translates to "breed survey", "bonitation" or "licensing".
Typically there are prerequisites in terms of pedigree and height, which vary depending on the registry. Most registries would like to see colts at least 15.3 hands high at the withers, and fillies at least 15.2hh, with the expectation that they will grow a bit more.
Pedigree requirements also vary, and many studbooks expect to see only stallion sons of Main Mare Book mares. This encourages local breeders to keep high-quality mares in the region. Preferably, future breeding stock have at least 4 generations of approved sport horse pedigree. Mares with less pedigree, or less than is desirable to her registry, may be entered into a "Pre-Mare Book", though she generally cannot produce stallion sons. What constitutes "approved" also depends on the registry.
Most studbook inspections follow a similar outline. The horse is judged on their conformation from each side, and then led to and away the judge(s) at the walk and trot on a hard surface to show the gaits. To evaluate the canter, horses are turned loose in an enclosed area one at a time. To evaluate jumping ability, the horse is sent down a chute over fences without a rider ("free jumping").
Horses are scored from 1 to 10 on a variety of traits, which may include any of the following: type, conformation, gaits, jumping, and overall impression.
Type is a subjective quality, divided into "breed type" and "sex type." A horse with high sex type exhibits strong secondary sex characteristics; in other words, feminine mares and masculine stallions. Breed type varies widely between registries, but essentially refers to the attractiveness of the horse and its suitability for sport. [1] This aesthetic is an important part of breeding marketable horses, though registries and their judges tend to be conscious of the danger of overweighing beauty. [1]
Standards of conformation do not vary as significantly for horses as they do for dogs, as a horse's conformation is extremely important to its ability to perform and stay sound doing so. Generally, all horses are ideally divisible into three equal parts: forehand, trunk, hindquarters. This is called "harmony" and has that effect on the eye. Another quality generally agreed upon is that from the front and rear, all four legs should be straight. Beyond that, uphill build, high-set neck, a mobile head-neck connection and long legs are more important in dressage horses than jumping horses. The musculature and outline of the back and loin, called the topline, is important to most registries, as are large joints and hooves with "dry" legs.
Conformation scores are usually broken down further to allow breeders to compare specific traits in horses - for instance the "forelimbs" and "hindlimbs" are almost always awarded separate scores.
The walk, trot, and canter are the gaits needed for sport. All three are important for dressage, and the canter is especially important for jumping. In all three, a long stride and even rhythm are paramount. Most registries look for a diligent, marching walk in which the entire body is used. The trot and canter are ideally energetic with obvious suspension (moment in which the horse is totally airborne) and an elastic quality. The energy for all three gaits should come from the hind end.
Scores may be given for "walk", "trot" and "canter" individually, with a separate score for "correctness of gaits". Some registries do not ask to see the mare canter, though this is uncommon. The canter is, in some cases, weighted more heavily for jumping mares.
The free jump can give insight into the jumping talent of a horse. At inspections, stallions in particular are judged on their ability to jump and their form. The best jumpers approach the jump confidently and alter their stride to find the correct take-off spot ("scope"), arc over the jump ("bascule") and draw their forelegs up out of the way. Horses that do not arc over the fence, knock down fences, lose their rhythm, dangle their legs or hold their heads high and stiff are not good jumpers.
All registries require stallions to free jump to pass the studbook inspection, though usually dressage-oriented stallions are not asked to jump as high. Mares may not jump at all, or may only be asked to jump if they are from jumping-oriented families.
The category for "overall impression" gives the judge(s) a place to comment on other qualities. Obvious behavioral tendencies or personality traits may be noted here, as is the physical maturity of the horse.
Most registries require that a stallion earn an average 7.0 with no score below 5.0 to be licensed. Mares who do not earn a sufficient score (usually average 6.0 none below 5.0) are usually entered into the Pre-Mare Book.
Almost all studbooks have some type of health requirement for stallions seeking approval. The veterinary exam may occur before, during, or after the Körung, and always rules out stallions with congenital defects of the genitalia or dentition. Stallions may also undergo radiographs to screen against OCD, laryngoscopies to screen against airway obstructions, and semen analysis to ensure fertility. Stallions which have had surgeries or other treatments to correct a congenital defect are not allowed to breed. Based on the registry, stallions may have to be free of cribbing, recurrent airway obstruction ("heaves"), equine recurrent uveitis ("moon blindness"), laryngeal hemiplegia ("roaring"), glanders, etc.
Performance tests take place when the breeding horses are old enough to be ridden, and are designed to give the registry detailed, objective information on the actual performance ability of the horses. It is mandatory for a stallion to prove himself in sport, and mares complete performance requirements to earn awards.
Mare performance tests (German : Stutenleistungsprüfung) are often open to geldings, as well. By comparing mother-daughter scores, patterns in the traits that stallions pass on can be calculated. A performance test for mares or geldings is either a one-day "Field Test" or 2- to 5-week "Station Test".
A stallion performance test (German : Hengsteigenleistungsprüfung) is either a 30-day "suitability test", or a "station test" lasting 70, 100, or even 300 days. Today, only young stallions owned by the State Stud of Celle attend the 300-Day Test. The suitability test must be combined with a performance record in order to fulfill a stallion's performance requirement.
The field test lasts only one day and is designed for mares and geldings with some education under saddle. In a field test, the horse is scored on the basic gaits, free jumping ability, and rideability. A guest rider is also used.
The station test is attended by young horses, held separately for stallions, is made up of an initial training period and a final test. The training environment, usually held at one of the state-owned stud farms, is standardized to increase the reliability of the results. Before the final test, the training director scores the horses on a number of traits. The final test is run by visiting experts and guest riders, who also score the horses. The results of the station test provide insight into the physical ability and the interior qualities that make a riding horse a good partner. Horses attending a station test are evaluated on the following:
The scores for the "inner" qualities are given by the training director, who depends on the input of the horse's riders and handlers. The interior qualities include character, temperament, constitution, and willingness. A horse with a good character is affable and people-oriented, and does not display defensive reactions such as ear-pinning during grooming, saddling, or everyday handling. A horse with a good temperament is balanced, attentive, responsive, sensitive with a desire to please. A horse with a good constitution is resilient physically and psychologically, not succumbing to pressure, and is healthy with a lot of stamina. A willing horse is courageous, curious, trainable and does not balk from being asked to work.
The basic gaits are evaluated under saddle both during the training period and by the guest experts. The regulations require that the movements be as natural as possible. A good walk is flat-footed with a regular 4-beat rhythm, diligent with long stride. A poor walk is arhythmical, pacey or short-strided. A good trot and canter are rhythmical and never disconnected. The stride is long, the horse swings through a relaxed topline. The trot and canter are elastic and give the impression that the horse is pushing from the rear. In particular, the canter must have a distinct uphill tendency. Short or choppy canter strides are not desirable.
Jumping is scored a number of different ways. The training director scores his or her general impression of the horse's aptitude, and the experts evaluate the horse while jumping with and without a rider. A good jumper never loses the rhythm of his canter. He approaches the jump in balance, arcs over the fence (bascule), draws both the front and rear legs out of the way, and adapts his stride to the space between the jumps (scope).
Rideability is scored by both the training director and the guest riders, and is of paramount importance. A highly rideable horse is comfortable and uncomplicated to ride, and does not require the rider to hold him or her up (self-carriage). The horse is balanced, attentive, intelligent and obedient.
The cross-country test serves to test the stallion's stamina, though he is also judged on his canter and jumping during this part of the final test. His recovery time and heart rate are taken as part of the veterinary examination.
The 70-Day, 100-Day and 300-Day tests fulfill a stallion's performance requirements, and both the station and field tests satisfy a mare or gelding's. A stallion that attends the suitability test must perform at an age-appropriate level in open competition to complete his requirements. A mare or stallion may also fulfill these requirements with performance at a higher level of competition. Most registries prefer to see show results in dressage and show jumping, though eventing and combined driving are sometimes permitted. Some North American branches of sport horse registries even accept show results in show hunters.
Registries may have further requirements for stallions to retain their approval for breeding. Most will disapprove a stallion whose offspring do not fit the breeding aim.
In the past, registries offered breeders a monetary prize or "premium" for exceptional mares. The condition of accepting the prize was that the mare couldn't be exported, a method of ensuring that high-quality mare lines were not lost. Today, mares can earn the "States Premium" award by receiving above-average scores on her studbook inspection and completing the performance requirements. Such a mare is recognized by the prefix "St.Pr.St." or "SPS" before her name. Mares who complete these requirements but don't fit the pedigree regulations can earn the "Verbands Premium" or "Registry Premium", which has the prefix "V.Pr.St.". A stallion may also earn a premium.
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.
The Groninger or Groningen is a Dutch horse breed developed for light draft and agricultural work. It is closely related to heavy warmblood breeds like the East Friesian and Alt-Oldenburger. The breed was nearly lost in the mid-20th century because a significant number of mares were used for crossbreeding to create the Dutch Warmblood, leaving few purebreds.
The Friesian is a horse breed originating in Friesland in north Netherlands. The breed nearly became extinct on more than one occasion. It is classified as a light draught horse, and the modern day Friesian horse is used for riding and driving. The Friesian horse is most known for its all-black coat colour, its long flowing mane and tail, feathering on its legs, a high head carriage, and high stepping action.
The Hanoverian or Hannoveraner is a German breed or stud-book of warmblood sport horse. As with other German warmblood breeds, eligibility for registration depends on performance rather than ancestry.
"English pleasure" is the generic term for a number of different English riding classes seen at horse shows in the United States, where the horse is ridden in either hunt seat or saddle seat tack.
The Oldenburg or Oldenburger is a warmblood horse from the north-western corner of Lower Saxony, what was formerly the Grand Duchy of Oldenburg. The breed was built on a mare base of all-purpose farm and carriage horses, today called the Alt-Oldenburger. The modern Oldenburg is managed by the Association of Breeders of the Oldenburger Horse, which enacts strict selection of breeding stock to ensure that each generation is better than the last. Oldenburgers are tall sport horses with excellent gaits and jumping ability. The breeding of Oldenburg horses is characterized by very liberal pedigree requirements and the exclusive use of privately owned stallions rather than restriction to a state-owned stud farm.
The Selle Français (SF) is a breed of sport horse from France. An athletic horse with good gaits, it is usually bay or chestnut in color. The Selle Français was created in 1958 when several French riding horse breeds were merged into one stud book. The new breed was meant to serve as a unified sport horse during a period when horses were being replaced by mechanization and were transforming into an animal used mainly for sport and leisure.
The Dole Gudbrandsdal, Dølahest, or Dole is a draft- and harness-type horse from Norway. The Dole Trotter is alternately considered a subtype of the Dole Gudbrandsdal and a separate breed; it is also considered a part of the coldblood trotter type. The Dole Gudbrandsdal is a small draft horse, known for its pulling power and agility, while the Dole Trotter is a smaller, faster horse used for harness racing. The two types were previously commonly interbred, but the studbooks have been separate since 2000 and since 2016 the criteria for entry into the Gudbrandsdal horse studbook has required a strict critique of eligible mares. The Dole is originally from the Gudbrandsdal Valley, and is probably descended in part from the Friesian horse. Over time, the breed has had Thoroughbred, Arabian, and other breeds added in, especially during the creation of the Dole Trotter in the 19th century. The first studbook was created in 1941, and the current breed association was formed in 1947. Although originally used mainly as a pack horse, today, the heavier Dole type is used mainly for agricultural purposes. The Dole Gudbrandsdal been crossed with other breeds to develop horses for harness racing and riding.
A Dutch Warmblood or KWPN is a horse breed of warmblood type registered with the Royal Warmblood Studbook of the Netherlands [Koninklijk Warmbloed Paardenstamboek Nederland] (KWPN), which governs the breeding of competitive dressage and show jumping horses, as well as the show harness horse and Gelderlander, and a hunter studbook in North America. Developed through a breeding program that began in the 1960s, the Dutch Warmbloods are some of the most successful competition horses developed in postwar Europe.
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.
The Finnhorse or Finnish Horse is a horse breed with both riding horse and draught horse influences and characteristics, and is the only breed developed fully in Finland. In English it is sometimes called the Finnish Universal, as the Finns consider the breed capable of fulfilling all of Finland's horse needs, including agricultural and forestry work, harness racing, and riding. In 2007, the breed was declared the official national horse breed of Finland.
Florencio is a horse that won the 2004 World Championships for Young Dressage Horses in the five-year-old division. He was the only horse to receive a mark of "10" in the 2004 competition, and he received the highest marks total ever given to a combination at the World Championship for Young Horses. He stands at 16.2 hh (1.68m) and is registered in the following stud books: Westfalen, Oldenburg, NRPS, Hannover, AES, Sweden. His current rider is Hans Peter Minderhoud from.
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.
The Westphalian or Westfalen is a warmblood horse bred in the Westphalia region of western Germany. The Westphalian is closely affiliated with the state-owned stud farm of Warendorf, which it shares with the Rhinelander. Since World War II, the Westphalian horse has been bred to the same standard as the other German warmbloods, and they are particularly famous as Olympic-level show jumpers and dressage horses. Next to the Hanoverian, the Westphalian studbook has the largest breeding population of any warmblood in Germany.
The Bavarian Warmblood is a horse breed of southern Germany that developed from an older Bavarian heavy warmblood breed called the Rottaler. Since mechanization in the mid-20th century, the Bavarian Regional Horse Breeders' Society has concentrated on producing a riding horse for the Olympic disciplines and recreational riding based on other European warmblood bloodlines.
The Kentucky Mountain Saddle Horse is a horse breed from the U.S. state of Kentucky. Developed as an all-around farm and riding horse in eastern Kentucky, it is related to the Tennessee Walking Horse and other gaited breeds. In 1989 the Kentucky Mountain Saddle Horse Association (KMSHA) was formed, and in 2002, the subsidiary Spotted Mountain Horse Association (SMHA) was developed to register Kentucky Mountain Saddle Horses with excessive white markings and pinto patterns. Conformation standards are the same for the two groups of horses, with the main difference being the color requirements. The KMSHA studbook is now closed to horses from unregistered parents, although it cross-registers with several other registries, while the SMHA studbook remains open.
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.
The Frederiksborger is Denmark's oldest horse breed. They were tremendously popular throughout the Renaissance and Baroque periods and were considered luxury items. Today, the breed is rare, but has a loyal following. Stallions and mares undergo studbook inspections before being allowed to breed. They are most often chestnut with white markings.
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.
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).
