Cerebellar Abiotrophy
Cerebellar abiotrophy (CA), also called cerebellar cortical abiotrophy (CCA), is a genetic neurological disease in animals, best known to affect certain breeds of horses, dogs and cats. It can also develop in humans. It develops when the neurons known as Purkinje cells, located in the cerebellum of the brain, begin to die off. These cells affect balance and coordination. They have a critical role to play in the brain. The Purkinje layer allows communication between the granular and molecular cortical layers in the cerebellum. Put simply, without Purkinje cells, an animal loses its sense of space and distance, making balance and coordination difficult. People with damage to the cerebellum can experience symptoms like unsteady gait, poor muscle control, and trouble speaking or swallowing. ''Abiotrophy'' means the loss of a vital nutritive factor. The cause of cerebellar abiotrophy is not known, but it is thought to be due to an intrinsic metabolic defect. In most cases, the ...

Arabian Horse
The Arabian or Arab horse ( , DIN 31635, DMG ''al-ḥiṣān al-ʿarabī'') is a horse breed, breed of horse with historic roots on the Arabian Peninsula. With a distinctive head shape and high tail carriage, the Arabian is one of the most easily recognizable horse breeds in the world. It is also one of the oldest modern breeds. Although modern DNA cannot trace breed purity in the modern population beyond 200 years, there is archaeological evidence of horses in the Middle East with landrace characteristics that resemble modern Arabians dating back 3,500 years. Arabian horses have spread around the world by both war and trade, being used to improve other breeds by adding speed, refinement, endurance, and strong bone. Today, Arabian bloodlines are found in almost every modern breed of riding horse. The Arabian developed in a desert climate and was prized by the nomadic Bedouin people, often being brought inside the family tent for shelter and protection from theft. Selective ...

Domestic Shorthair
A moggy is any cat which has not been intentionally bred. Moggies lack a consistent appearance unlike purebred cats that are selectively bred for appearance conforming to a standard. In contexts where cats need to be registered—such as in veterinary practices or shelters—moggies may be called domestic short-haired (DSH) or domestic long-haired (DLH) cats, depending on coat length (and less common designations may include "domestic medium-haired (DMH)" or "domestic semi-long-haired"). The vast majority of cats worldwide lack any pedigree ancestry. History Cat fancying is relatively new and over 85% of cat breeds have come into existence since the 1930s. Demography In the United States, domestic short-haired cats make up 95% of the cat population. In the UK 89–92% of cats are of non-pedigree lineage. Domestic short-haired In the cat fancy, and among veterinarians and animal control agencies, domestic short-haired cats may be classified with organization-specific ter ...

Cerebellar Degeneration
Cerebellar degeneration is a condition in which cerebellar cells, otherwise known as neurons, become damaged and progressively weaken in the cerebellum. There are two types of cerebellar degeneration; paraneoplastic cerebellar degeneration, and alcoholic or nutritional cerebellar degeneration. As the cerebellum contributes to the coordination and regulation of motor activities, as well as controlling equilibrium of the human body, any degeneration to this part of the organ can be life-threatening. Cerebellar degeneration can result in disorders in fine movement, posture, and motor learning in humans, due to a disturbance of the vestibular system. This condition may not only cause cerebellar damage on a temporary or permanent basis, but can also affect other tissues of the central nervous system, those including the cerebral cortex, spinal cord and the brainstem (made up of the medulla oblongata, midbrain, and pons). Cerebellar degeneration can be attributed to a plethora of heredita ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uterus
The uterus (from Latin ''uterus'', : uteri or uteruses) or womb () is the hollow organ, organ in the reproductive system of most female mammals, including humans, that accommodates the embryonic development, embryonic and prenatal development, fetal development of one or more Fertilized egg, fertilized eggs until birth. The uterus is a hormone-responsive sex organ that contains uterine gland, glands in its endometrium, lining that secrete uterine milk for embryonic nourishment. (The term ''uterus'' is also applied to analogous structures in some non-mammalian animals.) In humans, the lower end of the uterus is a narrow part known as the Uterine isthmus, isthmus that connects to the cervix, the anterior gateway leading to the vagina. The upper end, the body of the uterus, is connected to the fallopian tubes at the uterine horns; the rounded part, the fundus, is above the openings to the fallopian tubes. The connection of the uterine cavity with a fallopian tube is called the utero ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cerebellar Hypoplasia (non-human)
Cerebellar hypoplasia is a neurological condition in which the cerebellum is smaller than usual or not completely developed. It has been reported in many animal species. Function and development of the cerebellum The cerebellum is the brain's main control center for planning, adjusting, and executing movements of the body, the limbs and the eyes. It plays a major role in several forms of motor learning, including balance and posture. In the past, the evidence for a role for the cerebellum in cognitive functions was rather weak. However, investigations into the cognitive neuroscience of the cerebellum are rapidly advancing, extending far beyond the traditional view. For humans, current theories support that what the cerebellum does to sensorimotor and vestibular control, it also does to cognition, emotion, and autonomic function. How it functions in cognition, emotion, or autonomic function in animals is still largely unknown. In 2012, a study in mice provided direct ev ...

Kerry Blue Terrier
The Kerry Blue Terrier (also known as the Irish Blue Terrier) () is a breed of dog. Originally bred to control vermin including rats, rabbits, badgers, ferrets, foxes, otters, hares, deer, and even wolves, over time the Kerry became a general working dog used for a variety of jobs including herding cattle and sheep. Despite a Kerry Blue winning Crufts (the most prestigious UK dog show) in 2000, it remains an "unfashionable" breed, and is distinctly uncommon; however, it is not as threatened as some of the other terrier breeds such as the Skye Terrier, Sealyham Terrier, and Dandie Dinmont Terrier. Description Appearance Some characteristics of the Kerry Blue Terrier include a long head, flat skull, deep chest, and a soft wavy-to-curly coat that comes in several shades of "blue", the general term outside this breed being progressive grey. Puppies are born black; the blue appears gradually as the puppy grows older, usually up to 2 years of age. The male Kerry Blue is usually ...

American Yorkshire Pig
The American Yorkshire is an American breed of large domestic pig. It is the most numerous pig breed in the United States. It derives from pigs of the British Large White or Yorkshire breed imported from the United Kingdom or from Canada at various times from about 1830 to the mid-twentieth century. History The Yorkshire was the traditional pig of the county of the same name in northern England. Some pigs were imported under this name to the United States in about 1830. They were large and white, and – untypically – had large lop-ears; some of them at least may in fact have been from Lincolnshire rather than Yorkshire. Within a short time these were seen in Minnesota and, under a variety of names, in Ohio. A stock company with the name American Yorkshire Club was started in St. Paul, Minnesota, in 1893, and a herd-book A breed registry, also known as a herdbook, studbook or register, in animal husbandry, the hobby of animal fancy, is an official list of animals wi ...

Sheep
Sheep (: sheep) or domestic sheep (''Ovis aries'') are a domesticated, ruminant mammal typically kept as livestock. Although the term ''sheep'' can apply to other species in the genus '' Ovis'', in everyday usage it almost always refers to domesticated sheep. Like all ruminants, sheep are members of the order Artiodactyla, the even-toed ungulates. Numbering a little over one billion, domestic sheep are also the most numerous species of sheep. An adult female is referred to as a ''ewe'' ( ), an intact male as a ''ram'', occasionally a ''tup'', a castrated male as a ''wether'', and a young sheep as a ''lamb''. Sheep are most likely descended from the wild mouflon of Europe and Asia, with Iran being a geographic envelope of the domestication center. One of the earliest animals to be domesticated for agricultural purposes, sheep are raised for fleeces, meat ( lamb, hogget or mutton), and milk. A sheep's wool is the most widely used animal fiber, and is usually harvested by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wiltshire Horn
The Wiltshire Horn is a breed of domestic sheep originally from Wiltshire in southern England raised for meat. The breed is unusual among native British breeds, for it has the unusual feature of moulting its short wool and hair coat naturally in spring, obviating the need for shearing. They are good mothers and have high fertility. History The Wiltshire Horn was until the eighteenth century one of the predominant sheep breeds of southern England. For hundreds of years, it served a clear function on the thin chalk soils of the Wiltshire Downs, requiring little shelter from the elements and providing dung and urine to fertilise the wheat-growing land. At the same time, it provided an easily managed source of quality meat, but the rising price of wool and a general move away from horned sheep had the breed suffer a dramatic decline throughout the 19th and 20th centuries. It was nearly extinct at the start of the 1900s. In 1923, in an attempt to save the breed, the Wiltshire Horn B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Merino
The Merino is a list of sheep breeds, breed or group of breeds of domestic sheep, characterised by very fine soft wool. It was established in Spain near the end of the Middle Ages, and was for several centuries kept as a strict Spanish monopoly; exports of the breed were not allowed, and those who tried risked capital punishment. During the eighteenth century, flocks were sent to the courts of a number of European countries, including France (where they developed into the Rambouillet (sheep), Rambouillet), Hungary, the Netherlands, Prussia, Saxony and Sweden. The Merino subsequently spread to many parts of the world, including South Africa, Australia, and New Zealand. They are presently common in South Africa. Numerous recognised breeds, strains and variants have developed from the original type; these include, among others, the American Merino and Delaine Merino in the Americas, the Australian Merino, Booroola Merino and Peppin Merino in Oceania, and the Gentile di Puglia, M ...

Cattle
Cattle (''Bos taurus'') are large, domesticated, bovid ungulates widely kept as livestock. They are prominent modern members of the subfamily Bovinae and the most widespread species of the genus '' Bos''. Mature female cattle are called cows and mature male cattle are bulls. Young female cattle are called heifers, young male cattle are oxen or bullocks, and castrated male cattle are known as steers. Cattle are commonly raised for meat, for dairy products, and for leather. As draft animals, they pull carts and farm implements. Cattle are considered sacred animals within Hinduism, and it is illegal to kill them in some Indian states. Small breeds such as the miniature Zebu are kept as pets. Taurine cattle are widely distributed across Europe and temperate areas of Asia, the Americas, and Australia. Zebus are found mainly in India and tropical areas of Asia, America, and Australia. Sanga cattle are found primarily in sub-Saharan Africa. These types, sometime ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holstein (cattle)
The Holstein Friesian is an international breed or group of breeds of dairy cattle. It originated in Frisia, stretching from the Dutch province of North Holland to the German state of Schleswig-Holstein. It is the dominant breed in industrial dairy farming worldwide, and is found in more than 160 countries. It is known by many names, among them Holstein, Friesian and Black and White. With the growth of the New World, a demand for milk developed in North America and South America, and dairy breeders in those regions at first imported their livestock from the Netherlands. However, after about 8,800 Friesians ( black pied German cows) had been imported, Europe stopped exporting dairy animals due to disease problems. Today, the breed is used for milk in the north of Europe, and for meat in the south of Europe. After 1945, European cattle breeding and dairy products became increasingly confined to certain regions due to the development of national infrastructure. This change led to ...
