Santa Gertrudis Cattle
The Santa Gertrudis is an American list of cattle breeds, breed of beef cattle. It is a taurine-indicine hybrid breed, descended from both zebu and European cattle. It was bred in the early twentieth century in Texas, and received official recognition in 1940. It has been exported to many countries including Australia, Brazil and South Africa, and has contributed to the development of a number of modern breeds, among them the Barzona and the Droughtmaster. History The Santa Gertrudis was developed on the King Ranch in southern Texas. The name derives from that of the Spanish-owned estate of , where in 1851 the King Ranch was established. The ranch was initially stocked with Texas Longhorn cattle. From about 1880 bulls of the British Hereford (cattle), Hereford and Beef Shorthorn breeds were used to improve them; substantial separate Shorthorn and Hereford herds were kept to supply the bulls. In 1910 a part-zebuine bull, descended from an Ongole bull imported in 1906 directly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 of their meat. Today, beef is the third most widely consumed meat in the world, after pork and poultry. As of 2018, the United States, Brazil, and China were the largest producers of beef. Beef can be prepared in various ways; cuts are often used for steak, which can be cooked to varying degrees of doneness, while trimmings are often ground or minced, as found in most hamburgers. Beef contains protein, iron, and vitamin B12. Along with other kinds of red meat, high consumption is associated with an increased risk of colorectal cancer and coronary heart disease, especially when processed. Beef has a high environmental impact, being a primary driver of deforestation with the highest greenhouse gas emissions of any agricultural product. ...

Afrikander (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] |
Red Brahman
The Brahman is an American breed of zebuine-taurine hybrid beef cattle. It was bred in the United States from 1885 from cattle originating in India, imported at various times from the United Kingdom, from India and from Brazil. These were mainly Gir, Guzerá and Nelore stock, with some Indu-Brasil, Krishna Valley and Ongole. The Brahman has a high tolerance of heat, sunlight and humidity, and good resistance to parasites. It has been exported to many countries, particularly in the tropics; in Australia it is the most numerous breed of cattle. It has been used in the creation of numerous taurine-indicine hybrids, some of which – such as the Brangus and Brahmousin – are established as separate breeds. History Zebuine (Asian humped) cattle were present in the United States from 1849, when a single bull of Indian origin was imported from the United Kingdom to South Carolina. In 1885 a pair of grey bulls was brought directly from India to Texas; one was large, weighing over ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Devon (cattle)
The Devon is a traditional British breed of beef cattle. It originated in, and is named for, the county of Devon in the West Country of England. It is a deep rich red in colour, and so may be known as the Devon Ruby or Red Ruby; it may also be called the North Devon to distinguish it from the South Devon. History The Devon is a traditional breed of the county of Devon in the West Country of England. A herd-book was started by John Tanner Davy in 1850. A breed society, the Devon Cattle Breeders' Society, was formed in 1884, and took over management of the herd-book. By the early twentieth century the Devon was widespread. A census in 1908 found a population of close to 500,000, outnumbered only by the Shorthorn – of which there were about ten times that number. In the United States In Australia Devons were popular for use in bullock teams for hauling cedar and other logs from the forests, which was pit sawn and then transported by bullock drawn wagons and timber j ...

Gelbvieh
Gelbvieh (, German for "yellow cattle") is a cattle breed originating in several Franconian districts of Bavaria, Germany in the mid-eighteenth century. It was originally a triple-purpose breed, used for milk, beef and draught power; the modern Gelbvieh is primarily used for beef production. History In the mid-nineteenth century, several breeds of local German cattle began to be combined into what would eventually be the Gelbvieh. The new breed was officially formed by 1920. Between 1998 and 2018 numbers in Germany fell steadily from approximately 10 000 to about 2 000. Gelbvieh have been introduced to several countries around the world, including Spain, Portugal, Great Britain, Canada, the United States, Australia, and South Africa, primarily through the use of artificial insemination and some live export. The first Gelbvieh genetics reached Canada in 1972 from Germany. Gelbvieh are currently the 6th largest beef breed in Canada with 3500 head registered yearly. The firs ...

Aberdeen Angus
The Aberdeen Angus, sometimes simply Angus, is a Scottish breed of small beef cattle. It derives from cattle native to the counties of Aberdeen, Banff, Kincardine and Angus in north-eastern Scotland. In 2018 the breed accounted for over 17% of the UK beef industry. The Angus is naturally polled and solid black or red, although the udder may be white. The cattle have been exported to many countries of the world; there are large populations in Australia, Canada, New Zealand, South America and the United States, where it has developed into two separate and distinct breeds, the American Angus and Red Angus. In some countries it has been bred to be taller than the native Scottish stock. Its conservation status worldwide is "not at risk"; in the United Kingdom the original Native Aberdeen Angus – cattle not influenced by cross-breeding with imported stock – is listed by the Rare Breeds Survival Trust as "at risk".

Bloat (ruminant)
Ruminal tympany, also known as ruminal bloat, is a disease of ruminant animals, characterized by an excessive volume of gas in the rumen. Ruminal tympany may be primary, known as frothy bloat, or secondary, known as free-gas bloat. In the rumen, food eaten by the ruminant is fermented by microbes. This fermentation process continually produces gas, the majority of which is expelled from the rumen by eructation (burping). Ruminal tympany occurs when this gas becomes trapped in the rumen. In frothy bloat (primary ruminal tympany), the gas produced by fermentation is trapped within the fermenting material in the rumen, causing a build up of foam which cannot be released by burping. In cattle, the disease may be triggered after an animal eats a large amount of easily fermenting plants, such as legumes, alfalfa, red clover, or white clover. Some legumes, such as sainfoin, birdsfoot trefoil and cicer milkvetch are not associated with causing bloat in cattle. In feedlot cattle, a diet ...

Tick-borne Disease
Tick-borne diseases, which afflict humans and other animals, are caused by infectious agents transmitted by tick bites. They are caused by infection with a variety of pathogens, including rickettsia and other types of bacteria, viruses, and protozoa. The economic impact of tick-borne diseases is considered to be substantial in humans, and tick-borne diseases are estimated to affect ~80 % of cattle worldwide. 18 tick-borne pathogens have been identified in the United States according to the Centers for Disease Control and at least 27 are known globally. New tick-borne diseases have been discovered in the 21st century, due in part to the use of molecular assays and next-generation sequencing. The occurrence of ticks and tick-borne illnesses in humans is increasing. Tick populations are spreading into new areas, in part due to climate change. Tick populations are also affected by changes in the populations of their hosts (e.g. deer, cattle, mice, lizards) and those hosts' p ...

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 developed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conservation Status
The conservation status of a group of organisms (for instance, a species) indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status exist and are in use at international, multi-country, national and local levels as well as for consumer use. International systems IUCN Red List of Threatened Species The IUCN Red List of Threatened Species is the best known worldwide conservation status listing and ranking system. Species are classified by the IUCN Red List into nine groups set through criteria such as rate of decline, population size, area of geographic distribution, and degree of population and distribution fragmentation. Also included are species that have gone ext ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
