Wensleydale (sheep)
The Wensleydale is a British breed of domestic sheep. It is named for the Wensleydale region of North Yorkshire, in the north of England, where it was bred in the early nineteenth century by cross-breeding a Dishley Leicester ram with local long-woolled sheep of a breed that is now extinct. It has a blue-grey face and long purled wool, and is among the heaviest of British sheep breeds. It is an endangered breed, and is categorised as "at risk" by the Rare Breeds Survival Trust The Rare Breeds Survival Trust is a conservation charity whose purpose is to secure the continued existence and viability of the native farm animal genetic resources (FAnGR) of the United Kingdom. It was founded in 1973 by Joe Henson to pres .... It is often used as a ram breed to cross with other breeds to obtain market lambs, and for its high-quality wool. History The mating of a Leicester ram with a Teeswater ewe in 1838 made the famous ram 'BLUE CAP' who was the first sire of the Wensle ...

Wensleydale Sheep, Suffolk Show
Wensleydale is the dale or upper valley of the River Ure on the east side of the Pennines, one of the Yorkshire Dales in North Yorkshire, England. It is one of only a few Yorkshire Dales not currently named after its principal river, but the older name, Yoredale, can still be seen on some maps and as the Yoredale Series of geological strata. The dale takes its name from the village of Wensley, once its market town. The valley is famous for its cheese, with the main commercial production at Hawes. Also famous are its ales from Theakston Brewery and Black Sheep Brewery in Masham. Most of the dale is within the Yorkshire Dales National Park. Part of lower Wensleydale, below East Witton, is within the Nidderdale Area of Outstanding Natural Beauty. Addlebrough, a fell, dominates the landscape of the upper dale, and Penhill at is prominent in the lower dale. History Wensleydale was the home of one of Yorkshire's most famous clans, the Metcalfes, after they emigrat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinct
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sheep Breeds Originating In England
Sheep or domestic sheep (''Ovis aries'') are domesticated, ruminant mammals 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 shearing. In Commonw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sheep Breeds
This is a list of breeds of domestic sheep. Domestic sheep (''Ovis aries'') are partially derived from mouflon (''Ovis gmelini'') stock, and have diverged sufficiently to be considered a different species.

Blue-faced Leicester
The Bluefaced Leicester (BFL) is a longwool breed of sheep which evolved from a breeding scheme of Robert Bakewell, in Dishley, Leicestershire in the eighteenth century. First known as the Dishley Leicester, and then the Hexham Leicester, because of the prevalence of the breed in Northumberland, the name Bluefaced Leicester became known at the beginning of the 20th century. In the 1970s, the Bluefaced Leicester was exported to Canada. Exported frozen semen from the United Kingdom is now used to expand the genetic diversity in Canada and the United States. This breed is raised primarily for meat, but their fleece is becoming increasingly popular for handspinning. Bluefaced Leicester sheep may also have brown on their face. The sell record has been set by a brown ram lamb selling for 23,000 guineas. Characteristics BFL sheep have curly, fine, rather lustrous wool which is one of the softest of the UK clip. The fleeces are not very heavy, only weighing . They have no wool on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endangered Breed (livestock)
In modern agriculture, a rare breed is a breed of poultry or livestock that has a very small breeding population, usually from a few hundred to a few thousand. Because of their small numbers, rare breeds may have a threatened conservation status, and they may be protected under regional laws. Many countries have organizations devoted to the protection and promotion of rare breeds, for which they each have their own definition. In botany and horticulture, the parallel to rare animal breeds are heirloom plants, which are rare cultivars. Definitions There are several definitions of "breed" and "rare breed". Breeds may be defined as a group of animals that share visible characteristics, such as Pinto horses, which are all spotted. A stricter definition insists that breeds are "consistent and predictable genetic entities", which means that individuals from that breed will produce offspring that is predictably similar to their genitors, and that this similarity is genetically based. ...

English Leicester
The Leicester Longwool is an English breed of sheep. Alternative names for the breed include: Leicester, Bakewell Leicester, Dishley Leicester, English Leicester, Improved Leicester and New Leicester. It was originally developed by 18th-century breeding innovator Robert Bakewell. It is now one of Britain's rarest breeds, categorised as "endangered" by the Rare Breeds Survival Trust, since fewer than 500 registered breeding females remain in the United Kingdom. History Leicester Longwool sheep date back to the 1700s, and were found in the Midland counties of England, originally developed in Dishley Grange, Leicestershire by Robert Bakewell. Bakewell was the foremost exponent of modern animal-breeding techniques in the selection of livestock. The Leicester Longwool in the 1700s was slow-growing and coarsely boned. They now have been developed to gain weight quickly and are fast-growing. Leicester Longwool was one of the first pure sheep breeds introduced to Australia, having ...

Wool Wensleydale Longwool Sheep White
Wool is the textile fibre obtained from sheep and other mammals, especially goats, rabbits, and camelids. The term may also refer to inorganic materials, such as mineral wool and glass wool, that have properties similar to animal wool. As an animal fibre, wool consists of protein together with a small percentage of lipids. This makes it chemically quite distinct from cotton and other plant fibres, which are mainly cellulose. Characteristics Wool is produced by follicles which are small cells located in the skin. These follicles are located in the upper layer of the skin called the epidermis and push down into the second skin layer called the dermis as the wool fibers grow. Follicles can be classed as either primary or secondary follicles. Primary follicles produce three types of fiber: kemp, medullated fibers, and true wool fibers. Secondary follicles only produce true wool fibers. Medullated fibers share nearly identical characteristics to hair and are long but lack crim ...

Cross-breeding
A crossbreed is an organism with purebred parents of two different breeds, varieties, or populations. ''Crossbreeding'', sometimes called "designer crossbreeding", is the process of breeding such an organism, While crossbreeding is used to maintain health and viability of organisms, irresponsible crossbreeding can also produce organisms of inferior quality or dilute a purebred gene pool to the point of extinction of a given breed of organism. A domestic animal of unknown ancestry, where the breed status of only one parent or grandparent is known, may also be called a crossbreed though the term "mixed breed" is technically more accurate. Outcrossing is a type of crossbreeding used within a purebred breed to increase the genetic diversity within the breed, particularly when there is a need to avoid inbreeding. In animal breeding, ''crossbreeds'' are crosses within a single species, while '' hybrids'' are crosses between different species. In plant breeding terminology, the term ' ...

Selective Breeding
Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together. Domesticated animals are known as breeds, normally bred by a professional breeder, while domesticated plants are known as varieties, cultigens, cultivars, or breeds. Two purebred animals of different breeds produce a crossbreed, and crossbred plants are called hybrids. Flowers, vegetables and fruit-trees may be bred by amateurs and commercial or non-commercial professionals: major crops are usually the provenance of the professionals. In animal breeding, techniques such as inbreeding, linebreeding, and outcrossing are utilized. In plant breeding, similar methods are used. Charles Darwin discussed how selective breeding had been successful in producing change over time in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
