Guernsey Cattle
The Guernsey is a breed of dairy cattle from the island of Guernsey in the Channel Islands. It is fawn or red and white in colour, and is hardy and docile. Its milk is rich in flavour, high in fat and protein, and has a golden-yellow tinge due to its high β-carotene content. The Guernsey is one of three Channel Island cattle breeds; the other two are the Alderney, which is now extinct, and the Jersey. History The Guernsey was bred on the Channel Island of Guernsey; it is first documented in the nineteenth century, and its origins are unknown. Cattle were brought to the island in the Middle Ages for draught work. It has been suggested that the Guernsey derives from cattle imported from the French mainland – brindled cattle from Normandy, and wheaten stock similar to the Froment du Léon of Brittany. There may also have been some influence from Dutch cattle in the 18th century. During that century large numbers of cattle were exported from the Channel Islands to Englan ...

Guernsey
Guernsey ( ; Guernésiais: ''Guernési''; ) is the second-largest island in the Channel Islands, located west of the Cotentin Peninsula, Normandy. It is the largest island in the Bailiwick of Guernsey, which includes five other inhabited islands – Alderney, Herm, Jethou, Lihou and Sark – and many small islets and rocks. The bailiwick has a population of 63,950, the vast majority of whom live on Guernsey, and the island has a land area of . Guernsey was part of the Duchy of Normandy until 1204, when the Channel Islands remained loyal to the English crown, splitting from mainland Normandy. In 1290, the Channel Islands were divided administratively and Guernsey became part of the Bailiwick of Guernsey. During the World War II, Second World War, Guernsey was invaded and occupied by Nazi Germany. After five years of occupation, the island was liberated on 9 May 1945, that date being celebrated annually as Liberation Day. Guernsey is administered as part of the Bailiwick of Gu ...

Brittany
Brittany ( ) is a peninsula, historical country and cultural area in the north-west of modern France, covering the western part of what was known as Armorica in Roman Gaul. It became an Kingdom of Brittany, independent kingdom and then a Duchy of Brittany, duchy before being Union of Brittany and France, united with the Kingdom of France in 1532 as a provinces of France, province governed as a separate nation under the crown. Brittany is the traditional homeland of the Breton people and is one of the six Celtic nations, retaining Culture of Brittany, a distinct cultural identity that reflects History of Brittany, its history. Brittany has also been referred to as Little Britain (as opposed to Great Britain, with which it shares an etymology). It is bordered by the English Channel to the north, Normandy to the northeast, eastern Pays de la Loire to the southeast, the Bay of Biscay to the south, and the Celtic Sea and the Atlantic Ocean to the west.

Cattle Breeds Originating In The Channel Islands
Cattle (''Bos taurus'') are large, domesticated, bovid ungulates widely kept as livestock. They are prominent modern members of the subfamily Bovinae and the most widespread species of the genus '' Bos''. Mature female cattle are called cows and mature male cattle are bulls. Young female cattle are called heifers, young male cattle are oxen or bullocks, and castrated male cattle are known as steers. Cattle are commonly raised for meat, for dairy products, and for leather. As draft animals, they pull carts and farm implements. Cattle are considered sacred animals within Hinduism, and it is illegal to kill them in some Indian states. Small breeds such as the miniature Zebu are kept as pets. Taurine cattle are widely distributed across Europe and temperate areas of Asia, the Americas, and Australia. Zebus are found mainly in India and tropical areas of Asia, America, and Australia. Sanga cattle are found primarily in sub-Saharan Africa. These types, sometimes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protein
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residue (biochemistry), residues. Proteins perform a vast array of functions within organisms, including Enzyme catalysis, catalysing metabolic reactions, DNA replication, Cell signaling, responding to stimuli, providing Cytoskeleton, structure to cells and Fibrous protein, organisms, and Intracellular transport, transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the Nucleic acid sequence, nucleotide sequence of their genes, and which usually results in protein folding into a specific Protein structure, 3D structure that determines its activity. A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20–30 residues, are rarely considered to be proteins and are commonly called pep ...

Vitamin A
Vitamin A is a fat-soluble vitamin that is an essential nutrient. The term "vitamin A" encompasses a group of chemically related organic compounds that includes retinol, retinyl esters, and several provitamin (precursor) carotenoids, most notably Β-Carotene, β-carotene (''beta''-carotene). Vitamin A has multiple functions: growth during embryo development, maintaining the immune system, and healthy vision. For aiding vision specifically, it combines with the protein opsin to form rhodopsin, the light-absorbing molecule necessary for both low-light (scotopic vision) and color vision. Vitamin A occurs as two principal forms in foods: A) retinoids, found in Animal source foods, animal-sourced foods, either as retinol or bound to a fatty acid to become a retinyl ester, and B) the carotenoids Α-Carotene, α-carotene (''alpha''-carotene), β-carotene, Γ-Carotene, γ-carotene (''gamma''-carotene), and the xanthophyll beta-cryptoxanthin (all of which contain β-ionone rings) that ...

Provitamin
A provitamin is a substance that may be converted within the body to a vitamin. The term previtamin is a synonym. The term "provitamin" is used when it is desirable to label a substance with little or no vitamin activity, but which can be converted to an active form by normal metabolic processes. Example Some provitamins are: * "Provitamin A" is a name for β-carotene, which has only about 1/6 the biological activity of retinol (vitamin A); the body uses an enzyme to convert β-carotene to retinol. In other contexts, both β-carotene and retinol are simply considered to be different forms ( vitamers) of vitamin A. * "Provitamin B5" is a name for panthenol, which may be converted in the body to vitamin B5 (pantothenic acid). * Menadione is a synthetic provitamin of vitamin K. * Provitamin D2 is ergosterol Ergosterol (ergosta-5,7,22-trien-3β-ol) is a mycosterol found in cell membranes of fungi and protozoa, serving many of the same functions that cholesterol serves in animal ...

Processed Meats
Processed meat is considered to be any meat that has been modified in order to either improve its taste or to extend its shelf life. Methods of meat processing include salting, curing, fermentation, smoking, and the addition of chemical preservatives. Processed meat is frequently made from pork or beef, but also poultry and others. It can contain meat by-products such as blood. Processed meat products include bacon, ham, sausages, salami, corned beef, jerky, hot dogs, lunch meat, canned meat, chicken nuggets, and meat-based sauces. ''Meat processing'' includes all the processes that change fresh meat, with the exception of simple mechanical processes such as cutting, grinding or mixing.Introductio/ref> Meat processing began as soon as people realized that cooking and salting helps to preserve fresh meat. It is not known when this took place; however, the process of salting and Drying (food), sun-drying was recorded in Ancient Egypt, while using ice and snow is credited to earl ...

Beef
Beef is the culinary name for meat from cattle (''Bos taurus''). Beef can be prepared in various ways; Cut of beef, cuts are often used for steak, which can be cooked to varying degrees of doneness, while trimmings are often Ground beef, 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 meat, processed. Beef has a high Environmental impact of meat production, environmental impact, being a primary driver of deforestation with the highest greenhouse gas emissions of any agricultural product. In prehistoric times, humans hunted aurochs and later domesticated them. Since that time, numerous beef cattle, breeds of cattle have been Selective breeding, bred specifically for the quality or quantity of their meat. Today, beef is the third most widely consumed meat in the world, aft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holstein-Friesian
The Holstein Friesian is an international breed or group of breeds of dairy cattle. It originated in Frisia, stretching from the Dutch province of North Holland to the German state of Schleswig-Holstein. It is the dominant breed in industrial dairy farming worldwide, and is found in more than 160 countries. It is known by many names, among them Holstein, Friesian and Black and White. With the growth of the New World, a demand for milk developed in North America and South America, and dairy breeders in those regions at first imported their livestock from the Netherlands. However, after about 8,800 Friesians ( black pied German cows) had been imported, Europe stopped exporting dairy animals due to disease problems. Today, the breed is used for milk in the north of Europe, and for meat in the south of Europe. After 1945, European cattle breeding and dairy products became increasingly confined to certain regions due to the development of national infrastructure. This change led to ...

Cross-breeding
A crossbreed is an organism with purebred parents of two different breeds, varieties, or populations. A domestic animal of unknown ancestry, where the breed status of only one parent or grandparent is known, may also be called a crossbreed though the term "mixed breed" is technically more accurate. Outcrossing is a type of crossbreeding used within a purebred breed to increase the genetic diversity within the breed, particularly when there is a need to avoid inbreeding. In animal breeding, ''crossbreeds'' are crosses within a single species, while '' hybrids'' are crosses between different species. In plant breeding terminology, the term ''crossbreed'' is uncommon, and no universal term is used to distinguish hybridization or crossing within a population from those between populations, or even those between species. Crossbreeding is the process of breeding such an organism. It can be beneficially used to maintain health and viability of organisms. However, irresponsible crossbree ...

Selective Breeding
Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together. Domesticated animals are known as breeds, normally bred by a professional breeder, while domesticated plants are known as varieties, cultigens, cultivars, or breeds. Two purebred animals of different breeds produce a crossbreed, and crossbred plants are called hybrids. Flowers, vegetables and fruit-trees may be bred by amateurs and commercial or non-commercial professionals: major crops are usually the provenance of the professionals. In animal breeding artificial selection is often combined with techniques such as inbreeding, linebreeding, and outcrossing. In plant breeding, similar methods are used. Charles Darwin discussed how selective breeding had been succ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
