Navajo-Churro Sheep
The Navajo-Churro, or Churro for short, (also American or Navajo Four-Horned) is a breed of domestic sheep originating with the Spanish Churra sheep obtained by Navajo, Hopi and other Native American nations around the 16th century during the Spanish Conquest. The breed is renowned for its hardiness and adaptability to extremes of climate. Its wool consists of a protective topcoat and soft undercoat. Some rams have four fully developed horns, a trait shared with few other breeds in the world. The Navajo-Churro has also gained popularity for its low-maintenance reputation, resistance to disease, and lean meat. Some say they are very personable. Ewes often birth twins. This breed is raised primarily for wool. History The Churra (renamed Churro by American frontiersmen) was first imported to North America in the 16th century and used to feed Spanish armies and settlers. By the 17th century Churros were popular with the Spanish settlers in the upper Rio Grande Valley. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oklahoma State University
Oklahoma (; Choctaw: ; chr, ᎣᎧᎳᎰᎹ, ''Okalahoma'' ) is a state in the South Central region of the United States, bordered by Texas on the south and west, Kansas on the north, Missouri on the northeast, Arkansas on the east, New Mexico on the west, and Colorado on the northwest. Partially in the western extreme of the Upland South, it is the 20th-most extensive and the 28th-most populous of the 50 United States. Its residents are known as Oklahomans and its capital and largest city is Oklahoma City. The state's name is derived from the Choctaw words , 'people' and , which translates as 'red'. Oklahoma is also known informally by its nickname, " The Sooner State", in reference to the settlers who staked their claims on land before the official opening date of lands in the western Oklahoma Territory or before the Indian Appropriations Act of 1889, which increased European-American settlement in the eastern Indian Territory.

Phenotype
In genetics, the phenotype () is the set of observable characteristics or traits of an organism. The term covers the organism's morphology or physical form and structure, its developmental processes, its biochemical and physiological properties, its behavior, and the products of behavior. An organism's phenotype results from two basic factors: the expression of an organism's genetic code, or its genotype, and the influence of environmental factors. Both factors may interact, further affecting phenotype. When two or more clearly different phenotypes exist in the same population of a species, the species is called polymorphic. A well-documented example of polymorphism is Labrador Retriever coloring; while the coat color depends on many genes, it is clearly seen in the environment as yellow, black, and brown. Richard Dawkins in 1978 and then again in his 1982 book '' The Extended Phenotype'' suggested that one can regard bird nests and other built structures such as ...

Sheep Breeds Originating From Indigenous Americans
Sheep or domestic sheep (''Ovis aries'') are domesticated, ruminant mammals 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 by shearing. In Commonw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Navajo Culture
The Navajo (; British English: Navaho; nv, Diné or ') are a Native Americans in the United States, Native American people of the Southwestern United States. With more than 399,494 enrolled tribal members , the Navajo Nation is the largest federally recognized tribe in the United States; additionally, the Navajo Nation has the largest Indian reservation, reservation in the country. The reservation straddles the Four Corners region and covers more than 27,325 square miles (70,000 square km) of land in Arizona, Utah, and New Mexico. The Navajo Reservation is slightly larger than the state of West Virginia. The Navajo language is spoken throughout the region, and most Navajos also speak English. The states with the largest Navajo populations are Arizona (140,263) and New Mexico (108,306). More than three-fourths of the enrolled Navajo population resides in these two states.

Slow Food
Slow Food is an organization that promotes local food and traditional cooking. It was founded by Carlo Petrini in Italy in 1986 and has since spread worldwide. Promoted as an alternative to fast food, it strives to preserve traditional and regional cuisine and encourages farming of plants, seeds, and livestock characteristic of the local ecosystem. It promotes local small businesses and sustainable foods. It also focuses on food quality, rather than quantity. It was the first established part of the broader slow movement. It speaks out against overproduction and food waste. It sees globalization as a process in which small and local farmers and food producers should be simultaneously protected from and included in the global food system. Organization Slow Food began in Italy with the founding of its forerunner organization, Arcigola, in 1986 to resist the opening of a McDonald's near the Spanish Steps in Rome.Carlo Petrini, William McCuaig (trans.), Alice Waters (foreword). ...

The Livestock Conservancy
The Livestock Conservancy, formerly known as the American Livestock Breeds Conservancy (ALBC) and prior to that, the American Minor Breeds Conservancy, is a nonprofit organization focused on preserving and promoting rare breeds, also known as "heritage breeds" of livestock. Founded in 1977, through the efforts of livestock breed enthusiasts concerned about the disappearance of many of the US's heritage livestock breeds, the Conservancy was the pioneer livestock preservation organization in the United States, and remains a leading organization in that field. It has initiated programs that have saved multiple breeds from extinction, and works closely with similar organizations in other countries, including Rare Breeds Canada. With 3,000 members, a staff of nine and a 19-member board of directors, the organization has an operating budget of almost half a million dollars. The Livestock Conservancy maintains a conservation priority list that divides endangered breeds of horses, asses, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wool
Wool is the textile fibre 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 properties similar to animal wool. As an animal fibre, wool consists of protein together with a small percentage of lipids. This makes it chemically quite distinct from cotton and other plant fibres, 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 lac ...

Man And Navajo-Churro Flock
A man is an adult male human. Prior to adulthood, a male human is referred to as a boy (a male child or adolescent). Like most other male mammals, a man's genome usually inherits an X chromosome from the mother and a Y chromosome from the father. Sex differentiation of the male fetus is governed by the SRY gene on the Y chromosome. During puberty, hormones which stimulate androgen production result in the development of secondary sexual characteristics, thus exhibiting greater differences between the sexes. These include greater muscle mass, the growth of facial hair and a lower body fat composition. Male anatomy is distinguished from female anatomy by the male reproductive system, which includes the penis, testicles, sperm duct, prostate gland and the epididymis, and by secondary sex characteristics, including a narrower pelvis, narrower hips, and smaller breasts without mammary glands. Throughout human history, traditional gender roles have often defined ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scur
A scur is an incompletely developed horn growth. In cattle, scurs are not attached to the skull, whereas horns are attached and have blood vessels and nerves. Scurs may also occur in sheep. Genetic Inheritance The gene for scurs is inherited separately from the polled gene in cattle. Not all polled animals lack the scur gene. Since horned is recessive to polled, no horned cattle carry the polled allele, but they may also carry scurs. In cattle, genetic expression of the scur gene is different from that of the dominant polled gene, in that the scur gene's expression depends on the sex of the animal. The scur gene is dominant in males and recessive in females. See also * Horn (anatomy) * Polled livestock * Livestock dehorning Dehorning is the process of removing the horns of livestock. Cattle, sheep, and goats are sometimes dehorned for economic and safety reasons. Disbudding is a different process with similar results; it cauterizes and thus destroys horn buds be .. ...

Jacob (sheep)
The Jacob is a British breed of domestic sheep. It combines two characteristics unusual in sheep: it is piebald—dark-coloured with areas of white wool—and it is often polycerate or multi- horned. It most commonly has four horns. The origin of the breed is not known; broken-coloured polycerate sheep were present in England by the middle of the seventeenth century, and were widespread a century later. A breed society was formed in 1969, and a flock book was published from 1972. The Jacob was kept for centuries as a "park sheep", to ornament the large estates of landowners. In modern times it is reared mainly for wool, meat and skins. History The origins of the Jacob are not known. It has been bred in the British Isles for several hundred years. Sheep of this kind, little different from the modern breed, were shown in paintings from about 1760 at Tabley House in Cheshire, and – by George Stubbs – at Wentworth Woodhouse in Yorkshire. In the de Tabley family, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polycerate
Polycerates (meaning "many-horned") are animals with more than two horns. Sheep Polycerate sheep breeds include the Hebridean, Icelandic, Jacob, Manx Loaghtan, Boreray and the Navajo-Churro. One example of a polycerate Shetland sheep was a ram kept by US President Thomas Jefferson for several years in the early 19th century in front of the White House. In the spring of 1808 this ram attacked several people who had taken shortcuts across the square, injuring some and actually killing a small boy. Because of selective breeding, polycerate sheep are increasingly rare in the British Isles and Spain, but some breeds can still be found in Asia. One example is the black-faced sheep of Tibet. Goats There have been incidents of polycerate goats (having as many as eight horns), although this is a genetic rarity thought to be inherited. The horns are most typically removed in commercial dairy goat herds, to reduce the injuries to humans and other goats. 4 horns are the norm for the Aust ...

Extinction
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
