East Friesian Sheep
The Fries Melkschaap is a Dutch and German breed of dairy sheep. It originates in the Frisia region, which includes parts of both northern Holland and north-western Germany. It has many names: the German stock is known as the , or in English as the East Friesian, the East Friesland Milch or the German Milksheep, while the Dutch equivalent is known as the Friesian Milk or Friesian Milksheep, or less often as the Friesian or West Friesian. Under suitable management conditions, it is among the highest-yielding of dairy sheep breeds. History The breed originates in the Frisia region of north-western Germany and northern Holland. Characteristics The Friesian sheep breeds are a heathland type sheep, the land environment in much of Frisia. The group includes related dairy breeds taking their names from, and probably largely originating in, West Friesland and Zeeland. Historically, the sheep were kept in small numbers by households for household milk. They do poorly in large, dens ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DAD-IS
DAD-IS is the acronym for the Domestic Animal Diversity Information System, a tool developed and maintained by the Food and Agriculture Organization of the United Nations as a part of its programme for management of animal genetic resources for food and agriculture. It includes a searchable database of information on animal breeds. Overview The FAO began to collect data on animal breeds in 1982. The first version of DAD-IS was launched in 1996 and the software has been updated several times; the fourth version was launched in 2017. DAD-IS includes a searchable database of information about animal breeds, the Global Databank for Animal Genetic Resources. It contains information on breed characteristics, uses, geographic distribution and demographics; more than images; and tools for generating user-defined reports; and has a multilingual interface and content. It also provides contact information for the national and regional coordinators for the programme. Data is collected ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Micron (wool)
A micron (micrometre) is the measurement used to express the diameter of wool fibre. Fine wool fibers have a low micron value. Fibre diameter is the most important characteristic of wool in determining its value. Every fleece comprises a very wide range of fibre diameters—for example a typical Merino fleece will contain fibres of as low as 10 microns in diameter, and there could be fibres with diameters exceeding 25 microns, depending on the age and health (or nutrition) of the sheep. What is usually referred to as wool's "micron" is the mean of the fibre diameters or average diameter. This may be measured in a number of different ways. Small samples can be taken from the side or fleece of a sheep and measured using a portable instrument such as an OFDA2000 (Optical Fibre Diameter Analyser); or a mobile instrument system called a Fleecescan. Both these systems have been studied extensively and if used correctly, they should give reasonably reliable results. Pre wool classing ...

Lacaune (sheep)
The Lacaune (Languedocien: ''La Cauna'') is a breed of domestic sheep originating near Lacaune in southern France. The native region of these sheep is the Tarn and Aveyron departments and surrounding areas. This region is collectively known as the "Roquefort Sector" which references the milk collection area. The Lacaune is the most widely used dairying sheep breed in France, with a population of about 800,000 ewes. Notably, it is the predominant breed used in the production of Roquefort cheese in France. History Sheep first came to that region of France around 4,000 to 6,000 years ago. The land was rough and desolate but the sheep could adapt well to it. In the mid-19th century, farmers began to add genetics from other local breeds to produce a hardy breed of sheep that produced a rich milk and good meat. This was the development of the dual-purpose breed of original Lacaune. The Lacaune has been used as a milking sheep in France for a very long time, but milking wasn't the domi ...

Awassi
The Awassi is a breed of dairy sheep of Near-Eastern fat-tailed type. It is the most widely distributed non-European dairy breed. It is known by many names, among them Arab, Baladi, Deiri, Gezirieh, Ivesi, Shami and Syrian. It is usually white with brown head and legs. History The Awassi is a traditional breed of dairy sheep of Near-Eastern fat-tailed type. Its origins are unknown, but it is thought to originate in the historic region of Mesopotamia – the area between the Euphrates and Tigris rivers, now in modern Iraq and Syria. The breed name is thought to derive from that of Al-ʿAwās, a Bedouin tribe of northern Syria. It is the most widely distributed non-European dairy breed and the most numerous sheep breed of south-west Asia. It is the principal sheep of Iraq and Syria and the only indigenous sheep of Israel, Jordan and Lebanon. It is reportedly present in eighteen countries in Africa, Asia and Europe, with a total population estimated in 2024 at head. The ...

Lactation
Lactation describes the secretion of milk from the mammary glands and the period of time that a mother lactates to feed her young. The process naturally occurs with all sexually mature female mammals, although it may predate mammals. The process of feeding milk in all female creatures is called ''nursing'', and in humans it is also called ''breastfeeding''. Newborn infants often produce some milk from their own breast tissue, known colloquially as witch's milk. In most species, lactation is a sign that the female has been pregnant at some point in her life, although in humans and goats, it can happen without pregnancy. Nearly every species of mammal has teats; except for monotremes, egg-laying mammals, which instead release milk through ducts in the abdomen. In only a handful of species of mammals, certain bat species, is milk production a normal Male lactation, male function. ''Galactopoiesis'' is the maintenance of milk production. This stage requires prolactin. Oxytocin is cr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wool
Wool is the textile fiber 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 some properties similar to animal wool. As an animal fiber, wool consists of protein together with a small percentage of lipids. This makes it chemically quite distinct from cotton and other plant fibers, 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 ...

Staple (textiles)
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, and 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 into 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 le ...

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 develope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
