Valais Blacknose
The Valais Blacknose, german: Walliser Schwarznasenschaf, italic=no, is a breed of domestic sheep originating in the Valais region of Switzerland. It is a dual-purpose breed, raised both for meat and for wool. History The breed originates in the mountains of the canton of Valais – from which its name derives – and of the Bernese Oberland. It is documented as far back as the fifteenth century, but the present German name was not used before 1884; the breed standard dates from 1962. In the past there was some cross-breeding with imported sheep, in the nineteenth century of Bergamasca and Cotswold stock, and in the twentieth century of the Southdown breed. Characteristics The Schwarznasenschaf is a mountain breed, well adapted to grazing on the stony pastures of its area of origin. Both rams and ewes are horned. Use The Valais Blacknose is a dual-purpose breed, reared for both meat and wool. The wool is coarse: fibre diameter averages approximately 38 microns, and s ...

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] |

Bernese Oberland
The Bernese Oberland ( en, Bernese Highlands, german: Berner Oberland; gsw, Bärner Oberland; french: Oberland bernois), the highest and southernmost part of the canton of Bern, is one of the canton's five administrative regions (in which context it is referred to as ''Oberland'' without further specification). It constitutes the Alpine region of the canton and the northern side of the Bernese Alps, including many of its highest peaks, among which the Finsteraarhorn (), the highest in both range and canton. The region essentially coincides with the upper basin of the Aare, the latter notably comprehending Lake Thun and Lake Brienz, the two large lakes of the region. On the banks of the lakes or the Aare are the main settlements of Thun, Spiez, Interlaken, Brienz and Meiringen.

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 ' ...

Bergamasca (sheep)
The Bergamasca is a breed of domestic sheep from the mountainous part of the province of Bergamo, in Lombardy in northern Italy. It originates from the area of the Val Brembana and the Val Seriana valleys, and is particularly associated with the plateau of Clusone. By the beginning of the 20th century it had spread through much of Lombardy; it is now raised in most parts of mainland Italy, particularly the province of Teramo in Abruzzo, where more than 80% of the registered stock are kept. The Bergamasca is also present in Brazil, Serbia and Venezuela. It is raised principally for meat, and is often used for cross-breeding with other meat breeds to improve meat yield. In Lombardy, it is traditionally raised by transhumant Transhumance is a type of pastoralism or nomadism, a seasonal movement of livestock between fixed summer and winter pastures. In montane regions (''vertical transhumance''), it implies movement between higher pastures in summer and lower val ... ma ...

Cotswold (sheep)
The Cotswold is a British breed of domestic sheep. It originates in, and is named for, the Cotswold hills of the southern midlands of England. It is a large long-woollen sheep, and is kept as a dual-purpose breed, providing both meat and wool. It is a rare breed: in 2021 it was listed as "at risk" on the watchlist of the Rare Breeds Survival Trust. History Cotswold sheep have been noted as commonly having a slightly golden coloured wool since the days of Drayton and Camden in England (circa late 16th century to early 17th century), with dark colours being exceedingly rare. This trait gave them the nickname of the "Golden Fleece Breed". In the Middle Ages, Cotswold wool was highly prized and sought-after across Europe for its golden sheen and wealthy English merchants who profited from the wool trade funded the construction of many impressive wool churches which stand in the Cotswolds to this day. Some old-time black "Cotswolds" historically hark back in some form or a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southdown (sheep)
The Southdown is a British breed of domestic sheep, the smallest of the British breeds. It is a shortwool breed, and the basis of the whole Down group of breeds. It was originally bred by John Ellman of Glynde, near Lewes in East Sussex, in about 1800. It has been exported to many countries; it has been of particular importance in New Zealand, where it was used in the breeding of Canterbury lamb. In the twenty-first century it is kept principally as a terminal sire. It is listed by the Rare Breeds Survival Trust among the UK native breeds; it was formerly listed as "priority" or "at risk". History From Mediaeval times, small grey-faced polled sheep were kept on the chalk uplands of the South Downs of the counties of Kent and Sussex in south-east England. From about 1780 John Ellman, of Glynde, near Lewes in East Sussex, began selectively breeding them to improve their productive qualities; there are no records of how this breeding was carried out. By the end of the century ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microns
The micrometre ( international spelling as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer (American spelling), also commonly known as a micron, is a unit of length in the International System of Units (SI) equalling (SI standard prefix "micro-" = ); that is, one millionth of a metre (or one thousandth of a millimetre, , or about ). The nearest smaller common SI unit is the nanometre, equivalent to one thousandth of a micrometre, one millionth of a millimetre or one billionth of a metre (). The micrometre is a common unit of measurement for wavelengths of infrared radiation as well as sizes of biological cells and bacteria, and for grading wool by the diameter of the fibres. The width of a single human hair ranges from approximately 20 to . The longest human chromosome, chromosome 1, is approximately in length. Examples Between 1 μm and 10 μm: * 1–10 μm – length of a typical bacterium * 3–8 μm – width of st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Staple Length
A staple fiber is a textile fiber of discrete length. The opposite is a filament fiber, which comes in continuous lengths. Staple length is a characteristic fiber length of a sample of staple fibers. It is an essential criterion in yarn spinning aids in cohesion and twisting. Compared to synthetic fibers, natural fibers tend to have different and shorter lengths. The quality of natural fibers like cotton is categorized on staple length such as short, medium, long-staple and, extra long. Gossypium barbadense, one of several cotton species, produces extra-long staple fibers. The staple fibers may be obtained from natural and synthetic sources. In the case of synthetics and blends, the filament yarns are cut to a predetermined length (staple length). ''The filament is <1 mm in maximum cross section (i.e., diameter, in most cases). A filament can be compared ... Manufactured fibers are produced either as continuous infinite length filaments or cut staple of desired length value.< ...
