Studbook Selection
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 ...

Horse
The horse (''Equus ferus caballus'') is a domesticated, one-toed, hoofed mammal. It belongs to the taxonomic family Equidae and is one of two extant subspecies of ''Equus ferus''. The horse has evolved over the past 45 to 55 million years from a small multi-toed creature, '' Eohippus'', into the large, single-toed animal of today. Humans began domesticating horses around 4000 BCE, and their domestication is believed to have been widespread by 3000 BCE. Horses in the subspecies ''caballus'' are domesticated, although some domesticated populations live in the wild as feral horses. These feral populations are not true wild horses, as this term is used to describe horses that have never been domesticated. There is an extensive, specialized vocabulary used to describe equine-related concepts, covering everything from anatomy to life stages, size, colors, markings, breeds, locomotion, and behavior. Horses are adapted to run, allowing them to quickly escape predators ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hand (length)
The hand is a non- SI unit of measurement of length standardized to . It is used to measure the height of horses in many English-speaking countries, including Australia, Canada, the Republic of Ireland, the United Kingdom, and the United States. It was originally based on the breadth of a human hand. The adoption of the international inch in 1959 allowed for a standardized imperial form and a metric conversion. It may be abbreviated to "h" or "hh". Although measurements between whole hands are usually expressed in what appears to be decimal format, the subdivision of the hand is not decimal but is in base 4, so subdivisions after the radix point are in quarters of a hand, which are inches. Thus, 62 inches is fifteen and a half hands, or 15.2 hh (normally said as "fifteen-two", or occasionally in full as "fifteen hands two inches"). Terminology "Hands" may be abbreviated to "h", or "hh". The "hh" form is sometimes interpreted as standing for "hands high". When spok ...

Overbite
Overbite is the extent of vertical ( superior-inferior) overlap of the maxillary central incisors over the mandibular central incisors, measured relative to the incisal ridges. The term overbite does not refer to a specific condition, nor is it a form of malocclusion. Rather an absent or excess overbite would be a malocclusion. Normal overbite is not measured in exact terms, but as a proportion (approximately 30–50% of the height of the mandibular incisors) and is commonly expressed as a percentage. Other terms confused with "overbite" Overbite is often confused with overjet, which is the distance between the maxillary anterior teeth and the mandibular anterior teeth in the anterior-posterior axis. "Overbite" may also be used commonly to refer to Class II malocclusion or retrognathia, though this usage can be considered incorrect. This is where the mesiobuccal cusp of the maxillary first molar is situated anterior to the buccal groove of the mandibular first molar; in ...

Cryptorchidism
Cryptorchidism, also known as undescended testis, is the failure of one or both testes to descend into the scrotum. The word is from Greek () 'hidden' and () 'testicle'. It is the most common birth defect of the male genital tract. About 3% of full-term and 30% of premature infant boys are born with at least one undescended testis. However, about 80% of cryptorchid testes descend by the first year of life (the majority within three months), making the true incidence of cryptorchidism around 1% overall. Cryptorchidism may develop after infancy, sometimes as late as young adulthood, but that is exceptional. Cryptorchidism is distinct from monorchism, the condition of having only one testicle. Though the condition may occur on one or both sides, it more commonly affects the right testis. A testis absent from the normal scrotal position may be: # Anywhere along the "path of descent" from high in the posterior (retroperitoneal) abdomen, just below the kidney, to the inguinal ring ...

Bascule (horse)
Bascule is the natural round arc a horse's body takes as it goes over a jump. The horse should rise up through its back, stretching its neck forward and down, when it reaches the peak of his jump. Ideally, the withers are the highest point over the fence. This is often described as the horse taking the shape of a dolphin jumping out of the water. Bascule can also refer more generally to the raising of the withers while the horse is in motion. Importance of bascule A horse with bascule is one with a "round" jump, while a horse with poor bascule may jump "flat" with his head in the air and his spine relatively straight. A hollowed back over the fence tends to prevent the animal from lifting his forearms very high, thus preventing the necessary tucking motion of his front legs to jump clear. Most naturally talented jumpers have good bascule. However, there are several very athletic horses that can jump great heights with considerably poor bascule due to sheer power. Some bascule ...

Free Jumping
Free jumping or loose jumping is the practice of jumping a horse without a rider. It is often conducted in a chute and is used most often to evaluate the jumping ability of horses too young to jump under saddle. The correlations between free jumping and eventual success in show jumping competition have been the subject of several studies. Free jumping is used as a diagnostic tool by most warmblood Warmbloods are a group of middle-weight horse types and breeds primarily originating in Europe and registered with organizations that are characterized by open studbook policy, studbook selection, and the aim of breeding for equestrian spor ... breeding societies to evaluate jumping prowess in breeding stock. This practice is used to build a horse's confidence over jumps without a rider's interference, to evaluate a horse's jumping ability, or to showcase a horse that is for sale. This training method is used in a variety of ways, both professionally and recreationally. Free jump ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canter
The canter and gallop are variations on the fastest gait that can be performed by a horse or other equine. The canter is a controlled three-beat gait, while the gallop is a faster, four-beat variation of the same gait. It is a natural gait possessed by all horses, faster than most horses' trot, or ambling gaits. The gallop is the fastest gait of the horse, averaging about . The speed of the canter varies between depending on the length of the horse's stride. A variation of the canter, seen in western riding, is called a lope, and is generally quite slow, no more than . Etymology Since the earliest dictionaries there has been a commonly agreed suggestion that the origin of the word "canter" comes from the English city of Canterbury, a place of pilgrimage in the Middle Ages, as referred to in '' The Canterbury Tales'', where the comfortable speed for a pilgrim travelling some distance on horseback was above that of a trot but below that of a gallop. However a lack of com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trot (horse Gait)
The trot is a ten-beat diagonal horse gait where the diagonal pairs of legs move forward at the same time with a moment of suspension between each beat. It has a wide variation in possible speeds, but averages about . A very slow trot is sometimes referred to as a jog. An extremely fast trot has no special name, but in harness racing, the trot of a Standardbred is faster than the gallop of the average non-racehorse, and has been clocked at over . On June 29, 2014, at Pocono Downs in Pennsylvania the Swedish standardbred Sebastian K trotted a mile in 1 minute, 49 seconds (quarters were passed at 26:2, 55:3 and 1,21:4). This is equivalent to a 1000-pace in 1.07,7 or 53.14 kilometers per hour or 33 miles per hour. From the standpoint of the balance of the horse, the trot is a very stable gait and does not require the horse to make major balancing motions with its head and neck.Harris, Susan E.

Show Jumping
Show jumping is a part of a group of English riding equestrian events that also includes dressage, eventing, hunters, and equitation. Jumping classes are commonly seen at horse shows throughout the world, including the Olympics. Sometimes shows are limited exclusively to jumpers. Sometimes jumper classes are offered in conjunction with other English-style events. Sometimes, show jumping is but one division of a very large, all-breed competition that includes a very wide variety of disciplines. Jumping classes may be governed by various national horse show sanctioning organizations, such as the United States Equestrian Federation or the British Showjumping Association. International competitions are governed by the rules of the International Federation for Equestrian Sports. Hunters or jumpers Show jumping events have hunter classes, jumper classes and hunt seat equitation classes. Hunters are judged subjectively on the degree to which they meet an ideal standard of man ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dressage
Dressage ( or ; a French term, most commonly translated to mean "training") is a form of horse riding performed in exhibition and competition, as well as an art sometimes pursued solely for the sake of mastery. As an equestrian sport defined by the International Equestrian Federation, dressage is described as "the highest expression of horse training" where "horse and rider are expected to perform from memory a series of predetermined movements." Competitions are held at all levels from amateur to the Olympic Games and World Equestrian Games. Its fundamental purpose is to develop, through standardized progressive training methods, a horse's natural athletic ability and willingness to perform, thereby maximizing its potential as a riding horse. At the peak of a dressage horse's gymnastic development, the horse responds smoothly to a skilled rider's minimal aids. The rider is relaxed and appears effort-free while the horse willingly performs the requested movement. The disc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sexual Dimorphism
Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most animals and some plants. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', which is when both biological sexes are phenotypically indistinguishable from each other. Overview Ornamentation and coloration Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles. Sexual selection leads to the exaggerat ...

Subjectivity
Subjectivity in a philosophical context has to do with a lack of objective reality. Subjectivity has been given various and ambiguous definitions by differing sources as it is not often the focal point of philosophical discourse.Bykova, Marina F. (February 2018). "On the Problem of Subjectivity: Editor's Introduction". ''Russian Studies in Philosophy''. 56: 1-5 - via EBSCOhost. However, it is related to ideas of consciousness, agency, personhood, philosophy of mind, reality, and truth. Three common definitions include that subjectivity is the quality or condition of: * Something being a ''subject'', narrowly meaning an individual who possesses conscious experiences, such as perspectives, feelings, beliefs, and desires. Solomon, Robert C. "Subjectivity," in Honderich, Ted. '' Oxford Companion to Philosophy (Oxford University Press, 2005), p.900. * Something being a ''subject'', broadly meaning an entity that has agency, meaning that it acts upon or wields power over some other ...
