Icelandic Sheep
The Icelandic is the Icelandic breed of domestic sheep. It belongs to the Northern European Short-tailed group of sheep, and is larger than most breeds in that group. It is thought that it was introduced to Iceland by Vikings in the late ninth or early tenth century. It is generally short-legged and stocky, slender and light-boned, and usually horned, although polled and polycerate animals can occur; there is a polled strain, the Kleifa. The fleece is double-coated and may be white or a variety of other colors; the face and legs are without wool. The sheep are highly resistant to cold, and are generally left unshorn for the winter. Icelandic ewes are highly prolific, with a lambing percentage of 175–220%. The Þoka (Thoka) gene is carried by some ewes, which may give birth to large litters of lambs. A unique strain within the population is the Leader sheep, which carries a hereditary ability or predisposition to lead other sheep safely over dangerous ground. History I ...

Lopi (knitting)
Lopi () is knitting wool made from the fleece of Icelandic sheep. The fleece is made up of two layers, each with a different kind of wool. The wet-resistant outer coat contains long, coarse fibres, while the insulating layer beneath consists of soft, short fibres. These are processed together to create lopi roving and yarn. The machine- carded roving is produced in disc-shaped rolls. This is the original unspun lopi first used for knitting c.1920s. More recently, lightly spun lopi yarn in different thicknesses has become available. Most wool produced in Iceland is processed by Ístex, the Icelandic Textile Company. They manufacture 3 types of spun lopi yarn and also unspun lopi. It comes in a variety of natural fleece shades, and in a range of dyed colours. Lopi from local producers is also available, for instance in Þingborg near Selfoss.

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.< ...

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] |
Lamb And Mutton
Lamb, hogget, and mutton, generically sheep meat, are the meat of domestic sheep, ''Ovis aries''. A sheep in its first year is a lamb and its meat is also lamb. The meat from sheep in their second year is hogget. Older sheep meat is mutton. Generally, "hogget" and "sheep meat" are not used by consumers outside Norway, New Zealand, South Africa, Scotland and Australia. Hogget has become more common in England, particularly in the North (Lancashire and Yorkshire) often in association with rare breed and organic farming. In South Asian and Caribbean cuisine, "mutton" often means goat meat.''Oxford English Dictionary'', 3rd edition, June 2003''s.v.'',_definition_1b_At_various_times_and_places,_"mutton"_or_"goat_mutton"_has_occasionally_been_used_to_mean_goat_meat.

Sheep's-milk
Sheep's milk (or ewes' milk) is the milk of domestic sheep. It is commonly used to make cultured dairy products such as cheese. Some of the most popular sheep cheeses include feta (Greece), ricotta (Italy), and Roquefort (France). Sheep breeds Specialized dairy breeds of sheep yield more milk than other breeds. Common dairy breeds include: * East Friesian (Germany) * Sarda (Italy) * Lacaune (France) * British Milk Sheep (UK) * Chios (Greece) * Awassi (Syria) * Assaf (Israel) * Zwartbles (Friesland, Netherlands) In the U.S., the most common dairy breeds are the East Friesian and the Lacaune. Meat or wool breeds do not produce as much milk as dairy breeds, but may produce enough for small amounts of cheese and other products. Milk production period Female sheep (ewes) do not produce milk constantly. Rather, they produce milk during the 80–100 days after lambing. Sheep naturally breed in the fall, which means that a majority of lambs are born in the winter or early spring. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allele
An allele (, ; ; modern formation from Greek ἄλλος ''állos'', "other") is a variation of the same sequence of nucleotides at the same place on a long DNA molecule, as described in leading textbooks on genetics and evolution. ::"The chromosomal or genomic location of a gene or any other genetic element is called a locus (plural: loci) and alternative DNA sequences at a locus are called alleles." The simplest alleles are single nucleotide polymorphisms (SNP). but they can also be insertions and deletions of up to several thousand base pairs. Popular definitions of 'allele' typically refer only to different alleles within genes. For example, the ABO blood grouping is controlled by the ABO gene, which has six common alleles (variants). In population genetics, nearly every living human's phenotype for the ABO gene is some combination of just these six alleles. Most alleles observed result in little or no change in the function of the gene product it codes for. However, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gene
In biology, the word gene (from , ; "...Wilhelm Johannsen coined the word gene to describe the Mendelian units of heredity..." meaning ''generation'' or ''birth'' or ''gender'') can have several different meanings. The Mendelian gene is a basic unit of heredity and the molecular gene is a sequence of nucleotides in DNA that is transcribed to produce a functional RNA. There are two types of molecular genes: protein-coding genes and noncoding genes. During gene expression, the DNA is first copied into RNA. The RNA can be directly functional or be the intermediate template for a protein that performs a function. The transmission of genes to an organism's offspring is the basis of the inheritance of phenotypic traits. These genes make up different DNA sequences called genotypes. Genotypes along with environmental and developmental factors determine what the phenotypes will be. Most biological traits are under the influence of polygenes (many different genes) as well as gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
