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] |
Zebu
The zebu (; ''Bos indicus'' or ''Bos taurus indicus''), sometimes known in the plural as indicine cattle or humped cattle, is a species or subspecies of domestic cattle originating in the Indian sub-continent. Zebu are characterised by a fatty hump on their shoulders, a large dewlap, and sometimes drooping ears. They are well adapted to withstanding high temperatures, and are farmed throughout the tropical countries, both as pure zebu and as hybrids with taurine cattle, the other main type of domestic cattle. Zebu are used as draught and riding animals, dairy cattle, and beef cattle, as well as for byproducts such as hides and dung for fuel and manure. Some small breeds such as the miniature zebu are also kept as pets. In 1999, researchers at Texas A&M University successfully cloned a zebu. In some regions, such as parts of India, cattle, especially zebu, have significant religious meaning. Taxonomy and name The scientific name ''Bos indicus'' was introduced by Carl Linnae ...

Red Fulani Cattle
The Red Fulani is an African breed of cattle found from Mali across Niger and northern Nigeria to Chad and Cameroon. Characteristics They are reddish-brown in colour with long lyre-shaped horns, and of the Sanga type, intermediate between Zebu and humpless cattle, with cervico-thoracic humps, though they appear more Zebu than most Sanga cattle. They are able to withstand heat, ticks, insect bites and scarcity of water and feed. Local names of the breed include Brahaza, Djafoun (Cameroon), Fellata (Chad and Ethiopia), Fogha, Gabassaé, Gadéhé, Hanagamba, Kréda (Chad), Mbororo, Rahaza, Red Fulani, Red Longhorn. Uses The breed is used for milk and meat production by nomadic herders in the arid Sahel The Sahel (; ar, ساحل ' , "coast, shore") is a region in North Africa. It is defined as the ecoclimatic and biogeographic realm of transition between the Sahara to the north and the Sudanian savanna to the south. Having a hot semi-arid c ....

Nguni Cattle
The Nguni is a cattle breed indigenous to Southern Africa. A hybrid of different Indian and later European cattle breeds, they were introduced by pastoralist tribes ancestral to modern Nguni people to Southern Africa during their migration from the North of the continent. The cattle breed is medium-sized and adapted to grazing on the highveld. Characteristics Nguni cattle are known for their fertility and resistance to diseases, being the favourite breed amongst the local Bantu-speaking people of southern Africa (South Africa, Eswatini, Namibia, Zimbabwe, Botswana, and Angola). They are characterised by their multicoloured skin, which can present many different patterns, but their noses are always black-tipped. They are a principal form of Sanga cattle, which originated as hybrids of Zebu and humpless cattle in East Africa. DNA analyses have confirmed that they are a combination of '' Bos indicus'' and ''Bos taurus'', that is a combination of different Zebu and European cattle ...

Drakensberger Cattle
The Drakensberger is a South African breed of cattle. It is a dual-purpose breed, reared both for milk and for meat. Its origins go back to the early nineteenth century, to the time of the Great Trek or earlier, when imported European stock from Holland with was cross-bred with black cattle of Sanga type obtained from nomadic pastoralist Khoikhoi peoples. It is one of several successful African composite breeds of Sanga and European stock. In the early days it was selected for adaptation to the sourveld biome of South Africa, and for black colour; it was kept principally along the Drakensberg escarpment, which gave rise to its modern name. It was established as a breed with the formation of the Drakensberger Cattle Breeders' Society in 1947.} History The origins of the Drakensberger go back to the early nineteenth century, to the time of the Great Trek or earlier, when imported European stock from Holland with was cross-bred with black cattle of Sanga type obtained from nom ...

Ankole (cattle)
The Ankole is a breed or group of breeds of African cattle, belonging to the broad Sanga cattle grouping of African breeds. It was probably introduced to Uganda between five and seven hundred years ago by nomadic pastoralists from more northerly parts of the continent. It is distributed in much of eastern and central Africa, particularly in Uganda, the Democratic Republic of the Congo, Rwanda, Burundi and parts of Tanzania. There are at least five distinct regional strains, some of which may be reported as breeds in their own right. These include: * the Bahima, found in Uganda and the Congo, associated with the Bahima and other peoples; * the Bashi in the Congo; * the Kigezi, kept by Bakiga people in the former Kigezi District of south-western Uganda * the Ruzizi, from the Ruzizi Valley between Lake Kivu and Lake Tanganyika * the Watusi, found in Burundi, Congo, Rwanda, Uganda and parts of Tanzania, associated with Watusi or Tutsi The Tutsi (), or Abatutsi (), are an ethn ...

Afrikaner Cattle
The Afrikaner, also known as the Africander, is a breed of taurine-indicine (" Sanga") cattle indigenous to South Africa. Huge herds of Sanga type cattle were herded by the Khoikhoi (Hottentots) when the Dutch established the Cape Colony in 1652. History Afrikaners share coancestry with the Nguni and Drakensberger breeds. They most likely diverged 655–960 years ago. Anecdotal evidence from Portuguese sailors suggest that herds of Afrikaner-like cattle had been kept by the Khoikhoi since at least the 15th Century. The breed almost became extinct in the early 20th century during the Second Boer War, their numbers depleted through destruction and due to an outbreak of Rinderpest that halved the country's total cattle population. After the war, programs were put in place to improve the breed. In 1912, the first Afrikaner studbook was formed in South Africa in order to control the breed's development. However, due to the recently depleted numbers of Afrikaner cattle, a high deg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abigar
Abigar are a breed of cattle found in Eastern Africa. They are classified as Sanga cattle. Although primarily dairy cattle, they are also slaughtered for their beef Beef is the culinary name for meat from cattle (''Bos taurus''). In prehistoric times, humankind hunted aurochs and later domesticated them. Since that time, numerous breeds of cattle have been bred specifically for the quality or quantity .... Cows produce approximately 750 kg of milk per lactation. The origin of Abigar cattle breed is found to be Gambella Regional State, especially the districts occupied by the Nuer people. The observed production & reproduction performance of the breed is promising under the prevailing stressful and challenging environment in the region. The Abigar cattle is said to be hardy animals in response to frequent disease outbreaks, drought and seasonal feed and water shortages and high temperature and heat loads. However, a gradually decreasing trend of Abigar cattle was repor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whole Genome Sequencing
Whole genome sequencing (WGS), also known as full genome sequencing, complete genome sequencing, or entire genome sequencing, is the process of determining the entirety, or nearly the entirety, of the DNA sequence of an organism's genome at a single time. This entails sequencing all of an organism's chromosomal DNA as well as DNA contained in the mitochondrial DNA, mitochondria and, for plants, in the chloroplast. Whole genome sequencing has largely been used as a research tool, but was being introduced to clinics in 2014. In the future of personalized medicine, whole genome sequence data may be an important tool to guide therapeutic intervention. The tool of DNA sequencing, gene sequencing at Single-nucleotide polymorphism, SNP level is also used to pinpoint functional variants from association studies and improve the knowledge available to researchers interested in evolutionary biology, and hence may lay the foundation for predicting disease susceptibility and drug response. ...

SNPs
In genetics, a single-nucleotide polymorphism (SNP ; plural SNPs ) is a germline substitution of a single nucleotide at a specific position in the genome. Although certain definitions require the substitution to be present in a sufficiently large fraction of the population (e.g. 1% or more), many publications do not apply such a frequency threshold. For example, at a specific base position in the human genome, the G nucleotide may appear in most individuals, but in a minority of individuals, the position is occupied by an A. This means that there is a SNP at this specific position, and the two possible nucleotide variations – G or A – are said to be the alleles for this specific position. SNPs pinpoint differences in our susceptibility to a wide range of diseases, for example age-related macular degeneration (a common SNP in the CFH gene is associated with increased risk of the disease) or nonalcoholic fatty liver disease (a SNP in the PNPLA3 gene is associated with incre ...

Bos Primigenius
The aurochs (''Bos primigenius'') ( or ) is an extinct cattle species, considered to be the wild ancestor of modern domestic cattle. With a shoulder height of up to in bulls and in cows, it was one of the largest herbivores in the Holocene; it had massive elongated and broad horns that reached in length. The aurochs was part of the Pleistocene megafauna. It probably evolved in Asia and migrated west and north during warm interglacial periods. The oldest known aurochs fossils found in India and North Africa date to the Middle Pleistocene and in Europe to the Holstein interglacial. As indicated by fossil remains in Northern Europe, it reached Denmark and southern Sweden during the Holocene. The aurochs declined during the late Holocene due to habitat loss and hunting, and became extinct when the last individual died in 1627 in Jaktorów forest in Poland. The aurochs is depicted in Paleolithic cave paintings, Neolithic petroglyphs, Ancient Egyptian reliefs and Bronze ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
