Standardbred
The Standardbred is an American horse breed best known for its ability in harness racing where they compete at either a trot or pace. Developed in North America, the Standardbred is recognized worldwide, and the breed can trace its bloodlines to 18th-century England. They are solid, well-built horses with good dispositions. Characteristics Standardbreds are generally well-muscled and similar to, but a bit heavier than, a Thoroughbred, with a large head often with a Roman nose profile, straight neck, sloping shoulder, defined withers, a deep girth, strong bone (legs) and hard feet. Standardbreds average and typically weigh between . They are most often bay, and less frequently brown, black, chestnut, gray or roan. Standardbreds are considered easy-to-train horses with a willing submissive nature. Gaits Standardbreds race either at a trot or pace. In the trot, the horse's legs move in diagonal pairs; when the right foreleg moves forward, so does the left hind l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harness Racing
Harness racing is a form of horse racing in which the horses race at a specific gait (a trot or a pace). They usually pull a two-wheeled cart called a sulky, spider, or chariot occupied by a driver. In Europe, and less frequently in Australia and New Zealand, races with jockeys riding directly on saddled trotters ( in French) are also conducted. Breeds In North America, harness races are restricted to Standardbred horses, although European racehorses may also be French Trotters or Russian Trotters, or have mixed ancestry with lineages from multiple breeds. Orlov Trotters race separately in Russia. The light cold-blooded Coldblood trotters and Finnhorses race separately in Finland, Norway and Sweden. Standardbreds are so named because in the early years of the Standardbred stud book, only horses who could trot or pace a mile in a ''standard'' time (or whose progeny could do so) of no more than 2 minutes, 30 seconds were admitted to the book. The horses have proportiona ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horse Harness
A horse harness is a device that connects a horse to a horse-drawn vehicle or another type of load to pull. There are two main designs of horse harness: (1) the Breastplate (tack)#Harness, breast collar or breaststrap, and (2) the Horse collar, full collar or collar-and-hames. For pulling heavy loads, a full collar is required because it distributes pressure over a larger area of the horse. An ill-fitting full collar can cause chafing on the horse's skin and can interfere with its breathing, as can a breast collar that is positioned too high. Putting harness on a horse is called ''harnessing'' or ''harnessing up''. Attaching the harness to the vehicle or load is called ''putting to'' in the British Isles, or ''hitching'' in North America. The order of putting on harness components varies by discipline, but when a horse collar is used, it is usually put on first. Harness components designed for other animals (such as the yoke used with oxen) are not suitable for horses and will ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thoroughbred
The Thoroughbred is a list of horse breeds, horse breed developed for Thoroughbred racing, horse racing. Although the word ''thoroughbred'' is sometimes used to refer to any breed of purebred horse, it technically refers only to the Thoroughbred breed. Thoroughbreds are considered "Hot-blooded horse, hot-blooded" horses that are known for their agility, speed, and spirit. The Thoroughbred, as it is known today, was developed in 17th- and 18th-century England, when native mares were Crossbreed, crossbred with imported stallion (horse), stallions of Arabian horse, Arabian, Barb horse, Barb, and Turkoman horse, Turkoman breeding. All modern Thoroughbreds can trace their pedigrees to three stallions originally imported into England in the 17th and 18th centuries, and to a larger number of foundation bloodstock, foundation mares of mostly English breeding. During the 18th and 19th centuries, the Thoroughbred breed spread throughout the world; they were imported into North America ...

Trot (horse Gait)
The trot is a two-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-horse racing, 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.

Canadian Pacer
The Canadian () is a horse breed from Canada. It is a strong, well-muscled horse, usually dark in colour. It is generally used for riding and driving. Descended from draft and light riding horses imported to Canada in the late 1600s from France, it was later crossed with other British and American breeds. During the 18th century the Canadian horse spread throughout the northeastern US, where it contributed to the development of several horse breeds. During the peak popularity of the breed, three subtypes could be distinguished, a draft horse type, a trotting type and a pacing type. Thousands of horses were exported in the 19th century, many of whom were subsequently killed while acting as cavalry horses in the American Civil War. These exports decreased the purebred Canadian population almost to the point of extinction, prompting the formation of a studbook and the passage of a law against further export. Experimental breeding programs in the early 20th century succeeded in re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Osteochondrosis
Osteochondrosis is a family of orthopedic diseases of the joint that occur in children, adolescents and rapidly growing animals, particularly pigs, horses, dogs, and broiler chickens. They are characterized by interruption of the blood supply of a bone, in particular to the epiphysis, followed by localized bony necrosis, and later, regrowth of the bone. This disorder is defined as a focal disturbance of endochondral ossification and is regarded as having a multifactorial cause, so no one thing accounts for all aspects of this disease. Osteochondrosis is a developmental disease. It usually occurs in an early stage of life. It has personified features as focal chondronecrosis and confinement of growth cartilage due to a failing of endochondral ossification. Fissures can develop from lesions over the top articular cartilage and form a cartilage flap and an osteochondral fragment. It is diagnosed as osteochondritis dissecans. In animals In dogs osteochondrosis is seen in elbow, sho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Osteochondritis Dissecans
Osteochondritis dissecans (OCD or OD) is a joint disorder primarily of the subchondral bone in which cracks form in the articular cartilage and the underlying subchondral bone. OCD usually causes pain during and after sports. In later stages of the disorder there will be Swelling (medical), swelling of the affected joint that catches and locks during movement. Physical examination in the early stages does only show pain as symptom, in later stages there could be an Joint effusion, effusion, tenderness, and a crepitus, crackling sound with joint movement. OCD is caused by blood deprivation of the secondary physes around the bone core of the femoral condyle. This happens to the epiphyseal vessels under the influence of repetitive overloading of the joint during running and jumping sports. During growth such chondronecrotic areas grow into the subchondral bone. There it will show as bone defect area under articular cartilage. The bone will then possibly heal to the surrounding co ...

Narragansett Pacer
The Narragansett Pacer was the first horse breed developed in the United States during the 18th century from a mix of English and Spanish breeds, although the exact cross is unknown. It was closely associated with the state of Rhode Island, but it became extinct by the late 19th century. The Pacer was owned by many famous people of the day, including George Washington. The last known Pacer died around 1880. The Pacer was known as a sure-footed, dependable breed, although not flashy or always good-looking. Pacers were used for racing and general riding. They provided the foundation for several other American breeds, including the American Saddlebred, Standardbred, and Tennessee Walking Horse. History The Narragansett Pacer had a major influence on many American gaited horse breeds. It was especially associated with the state of Rhode Island in the early 18th century but became extinct by the late 19th century. It was known as the first breed of horse developed in America.

Horse Breed
A horse breed is a selectively bred population of domesticated horses, often with pedigrees recorded in a breed registry. However, the term is sometimes used in a broader sense to define landrace animals of a common phenotype located within a limited geographic region, or even feral "breeds" that are naturally selected. Depending on definition, hundreds of "breeds" exist today, developed for many different uses. Horse breeds are loosely divided into three categories based on general temperament: spirited "hot bloods" with speed and endurance; "cold bloods," such as draft horses and some ponies, suitable for slow, heavy work; and "warmbloods," developed from crosses between hot bloods and cold bloods, often focusing on creating breeds for specific riding purposes, particularly in Europe. Horse breeds are groups of horses with distinctive characteristics that are transmitted consistently to their offspring, such as conformation, color, performance ability, or disposition. Th ...

Norfolk Trotter
The Norfolk Trotter is a historical horse breed once native to East Anglia and Norfolk, England. It was said to be "a large-sized trotting harness horse originating in and around Norfolk". In 1542, King Henry VIII required the wealthy to keep a specified number of trotting-horse stallions. The breed was well established in Norfolk, and later became known as the Norfolk Trotter. The most influential sire in its history is the half-bred stallion Shales (foaled 1755), also known as "Old Shales". Shales' Thoroughbred sire, Blaze (foaled 1733), was a son of the great racehorse Flying Childers (a descendant of the Darley Arabian, one of the three foundation sires of the Thoroughbred). The Norfolk Trotter became the all-around travel horse in England at this time. In Yorkshire, the same breed was known as the Yorkshire Trotter. Both breeds were also known as roadsters. The term Norfolk/Yorkshire Roadster/Trotter is seen commonly in breed-history books; regardless of the name, all are t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transcription Factor
In molecular biology, a transcription factor (TF) (or sequence-specific DNA-binding factor) is a protein that controls the rate of transcription (genetics), transcription of genetics, genetic information from DNA to messenger RNA, by binding to a specific DNA sequence. The function of TFs is to regulate—turn on and off—genes in order to make sure that they are Gene expression, expressed in the desired Cell (biology), cells at the right time and in the right amount throughout the life of the cell and the organism. Groups of TFs function in a coordinated fashion to direct cell division, cell growth, and cell death throughout life; cell migration and organization (body plan) during embryonic development; and intermittently in response to signals from outside the cell, such as a hormone. There are approximately 1600 TFs in the human genome. Transcription factors are members of the proteome as well as regulome. TFs work alone or with other proteins in a complex, by promoting (a ...
