Ovis
''Ovis'' is a genus of mammals, part of the Caprinae subfamily of the ruminant family (biology), family Bovidae. Its seven highly sociable species are known as sheep or ovines. Domestic sheep are members of the genus, and are thought to be descended from the wild mouflon of central Asia, central and southwest Asia. Terminology Female sheep are called ''ewes'', males are called ''rams'' or less frequently ''bucks'' or ''tups'', neutered males are called ''wethers'', and young sheep are called ''lambs''. The adjective applying to sheep is ''ovine'', and the collective term for sheep is ''flock'' or ''mob''. The term ''herd'' is also occasionally used in this sense, generally for large flocks. Many Glossary of sheep husbandry, specialist terms relating to domestic sheep are used. Characteristics Sheep are fairly small compared to other ungulates; in most species, adults weigh less than .Nowak, R. M. and J. L. Paradiso. 1983. ''Walker's Mammals of the World''.

Mouflon
The mouflon (''Ovis gmelini'') is a wild sheep native to Cyprus, and the Caspian region, including eastern Turkey, Armenia, Azerbaijan, Georgia and Iran. It is also found in parts of Europe. It is thought to be the ancestor of all modern domestic sheep breeds. Taxonomy ''Ovis gmelini'' was the scientific name proposed by Edward Blyth in 1841 for wild sheep in the Middle East. In the 19th and 20th centuries, several wild sheep were described that are considered mouflon subspecies today: * ''Ovis ophion'' by Blyth in 1841 for wild sheep in Cyprus; * ''Ovis laristanica'' by Nikolai Nasonov in 1909 for wild sheep in Lar in southern Iran; * ''Ovis orientalis isphahanica'' by Nasonov in 1910 for wild sheep in the Zagros Mountains. Subspecies Five mouflon subspecies are distinguished by MSW3: * Armenian mouflon (Armenian red sheep), ''O. g. gmelini'' : nominate subspecies; native to northwestern Iran, Armenia, and Azerbaijan. It has been introduced to Texas in the U.S. * Esfahan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caprinae
The subfamily Caprinae, also sometimes referred to as the tribe Caprini, is part of the ruminant family Bovidae, and consists of mostly medium-sized bovids. A member of this subfamily is called a caprine. Prominent members include sheep and goats, with some other members referred to as goat antelopes. Some earlier taxonomies considered Caprinae a separate family called Capridae (with the members being caprids), but now it is usually considered either a subfamily within the Bovidae, or a tribe within the subfamily Antilopinae of the family Bovidae, with caprines being a type of bovid. Characteristics Although most goat-antelopes are gregarious and have fairly stocky builds, they diverge in many other ways – the muskox (''Ovibos moschatus'') is adapted to the extreme cold of the tundra; the mountain goat (''Oreamnos americanus'') of North America is specialised for very rugged terrain; the urial (''Ovis orientalis'') occupies a largely infertile area from Kashmir to Ira ...

Domestic Sheep
Sheep (: sheep) or domestic sheep (''Ovis aries'') are a domesticated, ruminant mammal 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bovidae
The Bovidae comprise the family (biology), biological family of cloven-hoofed, ruminant mammals that includes Bos, cattle, bison, Bubalina, buffalo, antelopes (including Caprinae, goat-antelopes), Ovis, sheep and Capra (genus), goats. A member of this family is called a bovid. With 143 Extant taxon, extant species and 300 known Extinction, extinct species, the family Bovidae consists of 11 (or two) major subfamilies and thirteen major tribes. The family evolved 20 million years ago, in the early Miocene. The bovids show great variation in size and Fur, pelage colouration. Except some Polled livestock, domesticated forms, all male bovids have two or more horn (anatomy), horns, and in many species, females possess horns, too. The size and shape of the horns vary greatly, but the basic structure is always one or more pairs of simple bony protrusions without branches, often having a spiral, twisted or fluted form, each covered in a permanent sheath of keratin. Most bovids bear 30 to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
10th Edition Of Systema Naturae
The 10th edition of ''Systema Naturae'' (Latin; the English title is ''A General System of Nature'') is a book written by Swedish naturalist Carl Linnaeus and published in two volumes in 1758 and 1759, which marks the starting point of zoological nomenclature. In it, Linnaeus introduced binomial nomenclature for animals, something he had already done for plants in his 1753 publication of ''Species Plantarum''. Starting point Before 1758, most biological catalogues had used polynomial names for the taxa included, including earlier editions of ''Systema Naturae''. The first work to consistently apply binomial nomenclature across the animal kingdom was the 10th edition of ''Systema Naturae''. The International Commission on Zoological Nomenclature therefore chose 1 January 1758 as the "starting point" for zoological nomenclature and asserted that the 10th edition of ''Systema Naturae'' was to be treated as if published on that date. Names published before that date are unavailable, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lamb And Mutton
Lamb and mutton, collectively sheep meat (or sheepmeat) is one of the most common meats around the world, taken from the domestic sheep, ''Ovis aries'', and generally divided into lamb, from sheep in their first year, hogget, from sheep in their second, and mutton, from older sheep. Generally, "hogget" and "sheep meat" aren't 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 2003Italian, make similar or even more detailed distinctions among sheep meats by age and sometimes by sex and diet—for example, ''lechazo'' in Spanish refers to meat from milk-fed (unweaned) lambs.

Ungulates
Ungulates ( ) are members of the diverse clade Euungulata ("true ungulates"), which primarily consists of large mammals with hooves. Once part of the clade "Ungulata" along with the clade Paenungulata, "Ungulata" has since been determined to be a polyphyletic and thereby invalid clade based on molecular data. As a result, true ungulates had since been reclassified to the newer clade Euungulata in 2001 within the clade Laurasiatheria while Paenungulata has been reclassified to a distant clade Afrotheria. Living ungulates are divided into two orders: Perissodactyla including equines, rhinoceroses, and tapirs; and Artiodactyla including cattle, antelope, pigs, giraffes, camels, sheep, deer, and hippopotamuses, among others. Cetaceans such as whales, dolphins, and porpoises are also classified as artiodactyls, although they do not have hooves. Most terrestrial ungulates use the hoofed tips of their toes to support their body weight while standing or moving. Two other orders o ...

Lichen
A lichen ( , ) is a hybrid colony (biology), colony of algae or cyanobacteria living symbiotically among hypha, filaments of multiple fungus species, along with yeasts and bacteria embedded in the cortex or "skin", in a mutualism (biology), mutualistic relationship.Introduction to Lichens – An Alliance between Kingdoms . University of California Museum of Paleontology. . Lichens are the lifeform that first brought the term symbiosis (as ''Symbiotismus'') into biological context. Lichens have since been recognized as important actors in nutrient cycling and producers which many higher trophic feeders feed on, such as reindeer, gastropods, nematodes, mites, and springtails. Lichens have properties different from those of their component organisms. They come in man ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stomach
The stomach is a muscular, hollow organ in the upper gastrointestinal tract of Human, humans and many other animals, including several invertebrates. The Ancient Greek name for the stomach is ''gaster'' which is used as ''gastric'' in medical terms related to the stomach. The stomach has a dilated structure and functions as a vital organ in the digestive system. The stomach is involved in the gastric phase, gastric phase of digestion, following the cephalic phase in which the sight and smell of food and the act of chewing are stimuli. In the stomach a chemical breakdown of food takes place by means of secreted digestive enzymes and gastric acid. It also plays a role in regulating gut microbiota, influencing digestion and overall health. The stomach is located between the esophagus and the small intestine. The pyloric sphincter controls the passage of partially digested food (chyme) from the stomach into the duodenum, the first and shortest part of the small intestine, where p ...

Digestion
Digestion is the breakdown of large insoluble food compounds into small water-soluble components so that they can be absorbed into the blood plasma. In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream. Digestion is a form of catabolism that is often divided into two processes based on how food is broken down: mechanical and chemical digestion. The term mechanical digestion refers to the physical breakdown of large pieces of food into smaller pieces which can subsequently be accessed by digestive enzymes. Mechanical digestion takes place in the mouth through Chewing, mastication and in the small intestine through segmentation contractions. In chemical digestion, enzymes break down food into the small compounds that the body can use. In the human digestive system, food enters the mouth and mechanical digestion of the food starts by the action of mastication (chewing), a form of mechanical digestion, and the wetting contact ...
