Romeldale
The Romeldale is an American breed of domestic sheep. It derives from cross-breeding of Romney rams and Rambouillet ewes from about 1915. The California Variegated Mutant is a rare badger-faced or variegated sub-type of the Romeldale. Some sources, as well as the breed association, refer to the two together as Romeldale/CVM. History The Romeldale was developed in the early 1900s by A.T. Spencer, who crossed Romney rams which had been exhibited at the 1915 Panama-Pacific International Exposition with his flock of Rambouillet ewes. The breeding focused on producing soft, fine wool and good fleece weight, as well as medium to large market lambs for meat. Development of the Romeldale continued throughout the 1940s and 50s, but a breed association for the original Romeldale alone was never formed and it is largely confined to its home state of California. California Variegated Mutant Glen Eidman, during the 1960s, found a unique pattern in one of his Romeldale ewes. After su ...

Domestic Sheep
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 (biology), 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 sheep milk, milk. A sheep's wool is the most widely used animal fiber, and is usually harvest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ' ...

Romney Sheep
The Romney, formerly called the Romney Marsh sheep but generally referred to by the local farmers as the Kent, is a breed of sheep originating in England. The Romney is a "long-wool" breed recognized in England by 1800. Exported to other continents, the Romney is an economically important sheep breed, especially to the sheep- meat and wool export trades of New Zealand. History of the breed Origins The breed evolved from medieval longwool types of which the Romney and Leicester breeds are early examples. The sheep recognized by 1800 as "Romney Marsh" or "Kent" were improved in body type and fleece quality through crossings with Bakewell's English Leicester. International spread The first confirmed export of Romneys from England was a shipment of 20 from Stone, Kent, that went on the ''Cornwall'' to New Zealand in 1853. With these and a further 30 ewes sent in 1856, Alfred Ludlum established New Zealand's first Romney Marsh stud in 1860 at Newry, in the Hutt Valley, and Ludlam' ...

Rambouillet Sheep
The Rambouillet is a breed of sheep in the genus Ovis. It is also known as the Rambouillet Merino or the French Merino. The development of the Rambouillet breed started in 1786, when Louis XVI purchased over 300 Spanish Merinos (318 ewes, 41 rams, seven wethers) from his cousin Charles III of Spain. The flock was subsequently developed on an experimental royal farm, the ''Bergerie royale'' (now ''Bergerie nationale'') built during the reign of Louis XVI, at his request, on his domain of Rambouillet, 50 km southwest of Paris, which Louis XVI had purchased in December 1783 from his cousin Louis Jean Marie de Bourbon, Duke of Penthièvre. The flock was raised exclusively at the ''Bergerie'', with no sheep being sold for several years, well into the 19th century. Outcrossing with English long-wool breeds and selection produced a well-defined breed, differing in several important points from the original Spanish Merino. The size was greater, with full-grown ewes weighing up to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animal Colouration
Animal coloration is the general appearance of an animal resulting from the reflection or emission of light from its surfaces. Some animals are brightly coloured, while others are hard to see. In some species, such as the peafowl, the male has strong patterns, conspicuous colours and is iridescent, while the female is far less visible. There are several separate reasons why animals have evolved colours. Camouflage enables an animal to remain hidden from view. Animals use colour to advertise services such as cleaning to animals of other species; to signal their sexual status to other members of the same species; and in mimicry, taking advantage of the warning coloration of another species. Some animals use flashes of colour to divert attacks by startling predators. Zebras may possibly use motion dazzle, confusing a predator's attack by moving a bold pattern rapidly. Some animals are coloured for physical protection, with pigments in the skin to protect against sunburn, whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oklahoma State University
Oklahoma (; Choctaw: ; chr, ᎣᎧᎳᎰᎹ, ''Okalahoma'' ) is a state in the South Central region of the United States, bordered by Texas on the south and west, Kansas on the north, Missouri on the northeast, Arkansas on the east, New Mexico on the west, and Colorado on the northwest. Partially in the western extreme of the Upland South, it is the 20th-most extensive and the 28th-most populous of the 50 United States. Its residents are known as Oklahomans and its capital and largest city is Oklahoma City. The state's name is derived from the Choctaw words , 'people' and , which translates as 'red'. Oklahoma is also known informally by its nickname, " The Sooner State", in reference to the settlers who staked their claims on land before the official opening date of lands in the western Oklahoma Territory or before the Indian Appropriations Act of 1889, which increased European-American settlement in the eastern Indian Territory.

The Livestock Conservancy
The Livestock Conservancy, formerly known as the American Livestock Breeds Conservancy (ALBC) and prior to that, the American Minor Breeds Conservancy, is a nonprofit organization focused on preserving and promoting rare breeds, also known as "heritage breeds" of livestock. Founded in 1977, through the efforts of livestock breed enthusiasts concerned about the disappearance of many of the US's heritage livestock breeds, the Conservancy was the pioneer livestock preservation organization in the United States, and remains a leading organization in that field. It has initiated programs that have saved multiple breeds from extinction, and works closely with similar organizations in other countries, including Rare Breeds Canada. With 3,000 members, a staff of nine and a 19-member board of directors, the organization has an operating budget of almost half a million dollars. The Livestock Conservancy maintains a conservation priority list that divides endangered breeds of horses, asses, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Handspinning
Spinning is an ancient textile arts, textile art in which fibre crop, plant, animal fibre, animal or synthetic fibre, synthetic fibres are drawn out and twisted together to form yarn. For thousands of years, fibre was spun by hand using simple tools, the Spindle (textiles), spindle and distaff. It was only with the invention of the spinning wheel in the Islamic world circa 1030, and its subsequent introduction to China, India and Europe in the High Middle Ages, that the output of individual spinners dramatically increased. Mass production later arose in the 18th century with the beginnings of the Industrial Revolution. Hand-spinning remains a popular handicraft. Characteristics of spun yarn vary according to the material used, fibre length and alignment, quantity of fibre used, and degree of twist. History The origins of spinning fibre to make string or yarn are lost in time, but archaeology, archaeological evidence in the form of representation of string skirts has been date ...

Polled Livestock
Polled livestock are livestock without horns in species which are normally horned. The term refers to both breeds and strains that are naturally polled through selective breeding and also to naturally horned animals that have been disbudded. Natural polling occurs in cattle, yaks, water buffalo, and goats, and in these animals it affects both sexes equally; in sheep, by contrast, both sexes may be horned, both polled, or only the females polled. The history of breeding polled livestock starts about 6000 years BC. Terminology The archaic term or is sometimes used to refer to hornless livestock (especially cattle) in folk songs, folk tales, and poetry, and in the name of the polled Irish Moiled cattle breed. "Muley" derives from Irish and Scottish Gaelic ''maol'', and Welsh ''moel''. Genetics In cattle, the polled allele is genetically dominant to that for horns. The polled trait is far more common in beef breeds than in dairy breeds. CRISPR technology is being developed t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
