Raya Cattle
The long-horned Raya cattle are a breed of cattle common in the Tigray Region of Ethiopia. The Raya cattle have red and black coat colours. Bulls and oxen have thick and long horns and a cervicothoracic hump The mountains and hills of the British Isles are categorised into various lists based on different combinations of elevation, prominence, and other criteria such as isolation. These lists are used for peak bagging, whereby hillwalkers attempt ...; cows have medium, thin horns. Raya cattle are closely related to the Afar cattle; this is a result of historical cattle raiding by the Raya people. The Raya cattle are however adapted to draught animals for tillage in the croplands of the highlands.

Cattle Breeds
List of cattle breeds — Over 1000 breeds of cattle are recognized worldwide, some of which adapted to the local climate, others which were bred by humans for specialized uses. Cattle breeds fall into two main types, which are regarded as either two closely related species, or two subspecies of one species. ''Bos indicus'' (or '' Bos taurus indicus'') cattle, commonly called zebu, are adapted to hot climates and originated in the tropical parts of the world such as India, Sub-saharan Africa, China, and Southeast Asia. ''Bos taurus'' (or ''Bos taurus taurus''), typically referred to as "taurine" cattle, are generally adapted to cooler climates and include almost all cattle breeds originating from Europe and northern Asia. In some parts of the world further species of cattle are found (both as wild and domesticated animals), and some of these are related so closely to taurine and indicus cattle that interspecies hybrids have been bred. Examples include the Dwarf Lulu cattle of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cattle Plague
Rinderpest (also cattle plague or steppe murrain) was an infectious viral disease of cattle, domestic buffalo, and many other species of even-toed ungulates, including gaurs, buffaloes, large antelope, deer, giraffes, wildebeests, and warthogs. The disease was characterized by fever, oral erosions, diarrhea, lymphoid necrosis, and high mortality. Death rates during outbreaks were usually extremely high, approaching 100% in immunologically naïve populations. Rinderpest was mainly transmitted by direct contact and by drinking contaminated water, although it could also be transmitted by air. After a global eradication campaign starting in the mid-20th century, the last confirmed case of rinderpest was diagnosed in 2001. On 14 October 2010, the United Nations Food and Agriculture Organization (FAO) announced that field activities in the decades-long, worldwide campaign to eradicate the disease were ending, paving the way for a formal declaration in June 2011 of the global eradica ...

Panzootic
A panzootic (from Greek παν all + ζόιον animal) is an epizootic (an outbreak of an infectious disease of animals) that spreads across a large region (for example a continent), or even worldwide. The equivalent in human populations is called a pandemic. A panzootic can start when three conditions have been met: * the emergence of a disease new to the population. * the agent infects a species and causes serious illness. * the agent spreads easily and sustainably among animals. A disease or condition is not a panzootic merely because it is widespread or kills a large number of animals; it must also be infectious. For example, cancer is responsible for a large number of deaths but is not considered a panzootic because the disease is, generally speaking, not infectious. Unlike an epizootic, a panzootic covers all or nearly all species over a large surface area (ex. rabies, anthrax). Typically an enzootic or an epizootic, or their cause, may act as a potential preparatory facto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interbreeding
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cull
In biology, culling is the process of segregating organisms from a group according to desired or undesired characteristics. In animal breeding, it is the process of removing or segregating animals from a breeding stock based on a specific trait. This is done to exaggerate desirable characteristics, or to remove undesirable characteristics by altering the genetic diversity of the population. For livestock and wildlife, culling often refers to the act of killing removed animals based on their individual characteristics, such as their sex or species membership, or as a means of preventing infectious disease transmission. In fruits and vegetables, culling is the sorting or segregation of fresh harvested produce into marketable lots, with the non-marketable lots being discarded or diverted into food processing or non-food processing activities. This usually happens at collection centres located at, or close to farms. Etymology The word ''cull'' comes from the Latin verb '' col ...

Arado Cattle
The red and black coated Arado cattle are small and hardy. They are the most common cattle variety in the north Ethiopian highlands. The Arado breed is part of the Zenga breed group. It is essentially reared for draught power, particularly tillage. The breed feeds mainly on crop residues; it is adapted to seasonal feed shortages. This breed is often cross-bred through bull and artificial insemination services. Physical characteristics The Arado cattle have red and black coats. Bulls and oxen have thick and short horns and a cervicothoracic hump; cows have medium, thin horns. Oxen weigh 254 kg and cows 201 kg on average. The average height at withers of 120 and 115 cm.

Pastoral
A pastoral lifestyle is that of shepherds herding livestock around open areas of land according to seasons and the changing availability of water and pasture. It lends its name to a genre of literature, art, and music (pastorale) that depicts such life in an idealized manner, typically for urban audiences. A ''pastoral'' is a work of this genre, also known as bucolic, from the Greek , from , meaning a cowherd. Literature Pastoral literature in general Pastoral is a mode of literature in which the author employs various techniques to place the complex life into a simple one. Paul Alpers distinguishes pastoral as a mode rather than a genre, and he bases this distinction on the recurring attitude of power; that is to say that pastoral literature holds a humble perspective toward nature. Thus, pastoral as a mode occurs in many types of literature (poetry, drama, etc.) as well as genres (most notably the pastoral elegy). Terry Gifford, a prominent literary theorist, define ...

Zenga
''Zenga'' is the term for the practice and art of Zen Buddhist painting and calligraphy in the Japanese tea ceremony and also the martial arts. Definition As a noun, Zenga is a style of Chinese and Japanese calligraphy and painting, done in ink. In many instances, both calligraphy and image will be in the same piece. The calligraphy denotes a poem, or saying, that teaches some element of the true path of Zen. The brush painting is characteristically simple, bold and abstract. History Though Zen Buddhism had arrived in Japan at the end of the 12th-century, Zenga (as here described) didn't come into its own until the beginning of the Edo period in 1600. Subject matter In keeping with individual paths to Enlightenment (spiritual), enlightenment, nearly any subject matter can lend (and has lent) itself to Zenga. Everything from a cat, to a bamboo shoot, to a man defecating in a field has been used to illustrate a particular point - although Ensō, enso, sticks and Mount Fuji are th ...

Sanga Cattle
Sanga cattle is the collective name for indigenous cattle of sub-Saharan Africa. They are sometimes identified as a subspecies with the scientific name ''Bos taurus africanus''. Their history of domestication and their origins in relation to taurine cattle, zebu cattle, and native African varieties of the ancestral aurochs are a matter of debate. Origins and Classification Near Eastern Introduction of Domesticated Cattle Into Africa The timeline for their history is the subject of extensive debate. A combination of genetic studies with archaeological research, including cultural history, has clarified the question of the complex origin of African cattle in recent years. Thus African cattle descend firstly from an aurochs domesticated in the Near East. After their introduction to Egypt, about eight thousand years ago, they spread all over the Sahara which was then still green, up to West Africa. The north African pastoralists interbred their domestic cattle with wild African ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pastoralism
Pastoralism is a form of animal husbandry where domesticated animals (known as "livestock") are released onto large vegetated outdoor lands (pastures) for grazing, historically by nomadic people who moved around with their herds. The animal species involved include cattle, camels, goats, yaks, llamas, reindeer, horses and sheep. Pastoralism occurs in many variations throughout the world, generally where environmental characteristics such as aridity, poor soils, cold or hot temperatures, and lack of water make crop-growing difficult or impossible. Operating in more extreme environments with more marginal lands means that pastoral communities are very vulnerable to the effects of global warming. Pastoralism remains a way of life in many geographic areas, including Africa, the Tibetan plateau, the Eurasian steppes, the Andes, Patagonia, the Pampas, Australia and many other places. , between 200 million and 500 million people globally practised pastoralism, and 75% ...
