Clydesdale Horse
The Clydesdale is a horse breed, breed of draught horse which originated in the seventeenth century, and takes its name from the Clydesdale (district), Clydesdale district of Scotland. The first recorded use of the name "Clydesdale" for the breed was in 1826; the horses spread through much of Scotland and into northern England. After the breed society was formed in 1877, thousands of Clydesdales were exported to other countries, particularly to Australia and New Zealand. In the early twentieth century numbers began to fall, both because many were taken for use in the First World War, and because of the increasing mechanisation of agriculture. By the 1970s, the Rare Breeds Survival Trust considered the breed vulnerable to extinction. Numbers have since increased slightly. Clydesdales are large and powerful, although now not as heavy as in the past. They were traditionally used for draught power, both in farming and in road haulage. They are now principally used as carriage horses ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bay (horse)
Bay is a equine coat color, hair coat color of horses, characterized by a reddish-brown or brown body color with a black point coloration on the mane (horse), mane, tail (horse), tail, Pinna (anatomy), ear edges, and lower legs. Bay is one of the most common coat colors in many horse breeds. The black areas of a bay horse's hair coat are called "black points", and without them, a horse is not a bay horse. Black points may sometimes be covered by white horse markings, markings; however such markings do not alter a horse's classification as "bay". Bay horses have dark skin – except under white markings, where the skin is pink. Genetically, bay occurs when a horse carries both at least one dominant Agouti gene and at least one dominant Extension gene. While the basic genetics that create bay coloring are fairly simple, the genes themselves and the mechanisms that cause shade variations within the bay family are quite complex and, at times, disputed. The genetics of dark shades ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Percheron
The Percheron is a horse breed, breed of draft horse that originated in the Huisne river valley in western France, part of the former Perche province, from which the breed takes its name. Usually gray (horse), gray or black (horse), black in color, Percherons are well-muscled, and known for their intelligence and willingness to work. Although their exact origins are unknown, the ancestors of the breed were present in the valley by the 17th century. They are believed to descend from war horse, war horses. Over time, they began to be used for pulling stagecoaches; and later, for agriculture and hauling heavy goods. In the late 18th and early 19th centuries, Arabian horse, Arabian blood was added to the breed. Exports of Percherons from France rose exponentially in the late 19th century, and the first purely Percheron stud book was created in France in 1893. Before World War I, thousands of Percherons were shipped from France to the United States, but after the war began, an embargo ...

Hyperkeratosis
Hyperkeratosis is thickening of the stratum corneum (the outermost layer of the epidermis, or skin), often associated with the presence of an abnormal quantity of keratin,Kumar, Vinay; Fausto, Nelso; Abbas, Abul (2004) ''Robbins & Cotran Pathologic Basis of Disease'' (7th ed.). Saunders. Page 1230. . and is usually accompanied by an increase in the granular layer. As the corneum layer normally varies greatly in thickness in different sites, some experience is needed to assess minor degrees of hyperkeratosis. It can be caused by vitamin A deficiency or chronic exposure to arsenic. Hyperkeratosis can also be caused by B-Raf inhibitor drugs such as vemurafenib and dabrafenib.Niezgoda, Anna; Niezgoda, Piotr; Czajkowski, Rafal (2015) ''Novel Approaches to Treatment of Advanced Melanoma: A Review of Targeted Therapy and Immunotherapy'' BioMed Research International It can be treated with urea-containing creams, which dissolve the intercellular matrix of the cells of the strat ...

Chronic Progressive Lymphedema
Chronic progressive lymphedema (CPL) is a disease of some breeds of draft horse, whereby the lower legs becomes progressively more swollen. There is no cure; the aim of treatment is to manage the signs and slow progression of the disease. The cause of CPL is not known, although it is suspected that a genetic disorder of elastin metabolism prevents the lymphatic vessels from functioning properly, leading to edema of the lower limbs. CPL resembles the human disease elephantiasis verrucosa nostra. Signs CPL is a progressive disease, which begins below the fetlock and gradually moves up the leg. All legs are affected, the hindlimbs usually more seriously so. Initial signs include thickening, crusting and folding of the skin. These early signs may be hidden by the long hair (feather) on the horse's lower legs. Affected areas are itchy, causing the horse to stamp its feet and rub its legs, and painful, so that the horse may be reluctant to allow its legs to be touched. As CPL progresse ...

Lameness (equine)
Lameness is an abnormal gait or stance of an animal that is the result of dysfunction of the Animal locomotion, locomotor system. In the horse, it is most commonly caused by pain, but can be due to neurologic or mechanical dysfunction. Lameness is a common veterinary problem in racehorses, sport horses, and Pleasure riding, pleasure horses. It is one of the most costly health problems for the Horse industry, equine industry, both monetarily for the cost of diagnosis and treatment, and for the cost of time off resulting in loss-of-use. Causes of lameness Lameness is most commonly caused by pain, but may also be the result of neuromuscular disease or mechanical restriction. Lameness itself is a clinical sign, and not a diagnosis. Pain Pain is the most common cause of lameness in the horse. It is usually the result of trauma or orthopedic disease, but other causes such as metabolic dysfunction, circulatory disease, and infection can also cause pain and subsequent lameness. Orthopedi ...

Cow-hocked
Cow-hocked ( adj.) or cow hocks ( n.) describes a defect in the conformation of four-legged animals, primarily of livestock and horses, but also of dogs and cats. Description An animal is cow-hocked when its hock is set inward, resulting in a splayed look in the back legs. This can result in the uneven wearing of hooves, which can end up in permanent lameness, and can prove to be a very serious condition. Permanent lameness usually results in the animal going for meat, as the cow will be in far too much pain to move, the milk in a cow will not be up to standard, and the animal could not be used in breeding, as this trait would pass on. However, most animals will not have too serious a condition, and will walk with a splayed-leg look. Another way of spotting cow-hock is when the hooves point outward as a result of the incorrect lineup of the joints in the leg. Another problem with cow-hocks is when the joints in the leg are not set correctly, the joints in the back will most li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feathering (horse)
Feathering or feather is the long hair on the lower legs of some breeds of horse and pony. On some horses, especially draft breeds, the hair can almost cover the hooves. While nearly all horses will grow longer hair on the lower legs and back of the fetlocks at times, particularly in the winter, "feather" refers to the particularly long growth that is characteristic of certain breeds. Feathering is a characteristic trait of many of the mountain and moorland pony breeds of the United Kingdom as well as draught breeds such as the Clydesdale, Shire Shire () is a traditional term for an administrative division of land in Great Britain and some other English-speaking countries. It is generally synonymous with county (such as Cheshire and Worcestershire). British counties are among the oldes ..., Friesian, Ardennes horse and Irish Cob. The trait may appear in crossbreds of these breeds, though to date there has been little scientific study of the trait. References Horse ...

Horse Markings
Markings on horses are usually distinctive white areas on an otherwise dark base equine coat color, coat color. Most horses have some markings, and they help to identify the horse as a unique individual. Markings are present at birth and do not change over the course of the horse's life. Most markings have pink skin underneath most of the white hairs, though a few faint markings may occasionally have white hair with no underlying pink skin. Markings may appear to change slightly when a horse grows or sheds its winter coat, however this difference is simply a factor of hair coat length; the underlying pattern does not change. On a gray (horse), gray horse, markings visible at birth may become hidden as the horse turns white with age, but markings can still be determined by trimming the horse's hair closely, then wetting down the coat to see where there is pink skin and black skin under the hair. Recent studies have examined the genetics behind white markings and have located ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roan (horse)
Roan is a horse coat color pattern characterized by an even mixture of colored and white hairs on the body, while the head and "point coloration, points"—lower legs, Mane (horse), mane, and tail—are mostly solid-colored. Horses with roan coats have white hairs evenly intermingled throughout any other color. The head, legs, mane, and tail have fewer scattered white hairs or none at all. The roan pattern is Dominance (genetics), dominantly inherited, and is found in many horse breeds. While the specific mutation responsible for roan has not been exactly identified, a DNA test can determine zygosity for roan in several breeds. True roan is always present at birth, though it may be hard to see until after the foal coat sheds out. The coat may lighten or darken from winter to summer, but unlike the Gray (horse), gray coat color, which also begins with intermixed white and colored hairs, roans do not become progressively lighter in color as they age.

Bay Clydesdale Lower Leg
A bay is a recessed, coastal body of water that directly connects to a larger main body of water, such as an ocean, a lake, or another bay. A large bay is usually called a ''gulf'', ''sea'', ''sound'', or ''bight''. A ''cove'' is a small, circular bay with a narrow entrance. A ''fjord'' is an elongated bay formed by glacial action. The term ''embayment'' is also used for , such as extinct bays or freshwater environments. A bay can be the estuary of a river, such as the Chesapeake Bay, an estuary of the Susquehanna River. Bays may also be nested within each other; for example, James Bay is an arm of Hudson Bay in northeastern Canada. Some large bays, such as the Bay of Bengal and Hudson Bay, have varied marine geology. The land surrounding a bay often reduces the strength of winds and blocks waves. Bays may have as wide a variety of shoreline characteristics as other shorelines. In some cases, bays have beaches, which "are usually characterized by a steep upper foreshore wit ...

Horse Gaits
Horses can use various gaits (patterns of leg movement) during locomotion across solid ground, either naturally or as a result of specialized training by humans.Ensminger, M. E. ''Horses and Horsemanship'' 6th edition USA: Interstate Publishers 1990 pp. 65–66 Classification Gaits are typically categorized into two groups: the "natural" gaits that most horses will use without special training, and the "ambling" gaits that are various smooth-riding, four-beat footfall patterns that may appear naturally in some individuals. Special training is often required before a horse will perform an ambling gait in response to a rider's command. Another system of classification that applies to quadrupeds uses three categories: walking and ambling gaits, running or trotting gaits, and leaping gaits.Tristan David Martin Roberts (1995) ''Understanding Balance: The Mechanics of Posture and Locomotion'', Nelson Thornes, The British Horse Society dressage rules require competitors to perfor ...

Hoof
The hoof (: hooves) is the tip of a toe of an ungulate mammal, which is covered and strengthened with a thick and horny keratin covering. Artiodactyls are even-toed ungulates, species whose feet have an even number of digits; the ruminants with two digits are the most numerous, e.g. giraffe, deer, bison, cattle, goats, gazelles, pigs, and sheep. The feet of perissodactyl mammals have an odd number of toes, e.g. the horse, the rhinoceros, and the tapir. Although hooves are limb structures primarily found in placental mammals, hadrosaurs such as '' Edmontosaurus'' possessed hoofed forelimbs. The marsupial '' Chaeropus'' also had hooves. Description The hoof surrounds the distal end of the second phalanx, the distal phalanx, and the navicular bone. The hoof consists of the hoof wall, the bars of the hoof, the sole and frog and soft tissue shock absorption structures. The weight of the animal is normally borne by both the sole and the edge of the hoof wall. Hooves perform man ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
