Bielefelder Kennhuhn
The Bielefelder Kennhuhn () or Bielefelder is a German breed of domestic chicken. It was developed in the area of Bielefeld in the 1970s by Gerd Roth, who cross-bred birds of Malines and Welsumer stock with American Barred Rocks to create the breed. Like other breeds with Barred Rock parentage, it is auto-sexing – chicks of different sexes can be distinguished by their colour. There is a bantam version, the Bielefelder Zwerg-Kennhuhn. History The concept of an auto-sexing chicken breed goes back to the work of Reginald Punnett in the 1920s and 1930s. The Bielefelder Kennhuhn was developed in the 1970s in the area of Bielefeld, in Ostwestfalen-Lippe in the state of Nordrhein-Westfalen. It was created by Gerd Roth by cross-breeding of birds of Malines and Welsumer stock with American Barred Rock birds. It was first exhibited in 1976 as the Deutsche Kennhuhn; in 1980, when the breed was recognised by the , the name was changed to Bielefelder Kennhuhn. In 2007 its conserv ...

It also provides contact information for the national and regional coordinators for the programme. Data is collected ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reginald Punnett
Reginald Crundall Punnett FRS (; 20 June 1875 – 3 January 1967) was a British geneticist who co-founded, with William Bateson, the ''Journal of Genetics'' in 1910. Punnett is probably best remembered today as the creator of the Punnett square, a tool still used by biologists to predict the probability of possible genotypes of offspring. His ''Mendelism'' (1905) is sometimes said to have been the first textbook on genetics; it was probably the first popular science book to introduce genetics to the public. Life and work Reginald Punnett was born in 1875 in the town of Tonbridge in Kent, England. While recovering from a childhood bout of appendicitis, Punnett became acquainted with Jardine's Naturalist's Library and developed an interest in natural history. Punnett was educated at Clifton College. Attending Gonville and Caius College, Cambridge, Punnett earned a bachelor's degree in zoology in 1898 and a master's degree in 1901. Between these degrees he worked as a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chicken Breeds
There are hundreds of chicken breeds in existence. Domesticated for thousands of years, distinguishable breeds of chicken have been present since the combined factors of geographical isolation and selection for desired characteristics created regional types with distinct physical and behavioral traits passed on to their offspring. The physical traits used to distinguish chicken breeds are size, plumage color, comb type, skin color, number of toes, amount of feathering, egg color, and place of origin. They are also roughly divided by primary use, whether for eggs, meat, or ornamental purposes, and with some considered to be dual-purpose. In the 21st century, chickens are frequently bred according to predetermined breed standards set down by governing organizations. The first of such standards was the British Poultry Standard, which is still in publication today. Other standards include the Standard of Perfection, the Australian Poultry Standard, and the standard of the America ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extensive Management
Extensive farming or extensive agriculture (as opposed to intensive farming) is an agricultural production system that uses small inputs of labour, fertilizers, and capital, relative to the land area being farmed. Systems Extensive farming most commonly means raising sheep and cattle in areas with low agricultural productivity, but includes large-scale growing of wheat, barley, cooking oils and other grain crops in areas like the Murray-Darling Basin in Australia. Here, owing to the extreme age and poverty of the soils, yields per hectare are very low, but the flat terrain and very large farm sizes mean yields per unit of labour are high. Nomadic herding is an extreme example of extensive farming, where herders move their animals to use feed from occasional rainfalls. Geography Extensive farming is found in the mid-latitude sections of most continents, as well as in desert regions where water for cropping is not available. The nature of extensive farming means it requires le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gesellschaft Zur Erhaltung Alter Und Gefährdeter Haustierrassen
The or GEH is a German national association for the conservation of historic and endangered domestic animal breeds. History The GEH was founded on 5 December 1981 in the Rottal, in Lower Bavaria in southern Germany. It has about 2100 members. Since it was founded, no domestic livestock breed has become extinct in Germany. Activities The GEH co-operates with other national and international organisations for the conservation of biodiversity. It publishes an annual Rote Liste or red list of endangered breeds of livestock, which attributes one of four categories of conservation risk to domestic breeds of cattle, dogs, goats, horses, pigs, rabbits and sheep, of chickens, ducks, geese and turkeys, and of bees; listing of domestic pigeon breeds is in preparation. Some breeds from outside Germany are listed separately. The four levels of risk are: * I: ', "extremely endangered" * II: ', "seriously endangered" * III: ', "endangered" * ', "alert" The risk level is calculated usin ...

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 are in use at international, multi-country, national and local levels, as well as for consumer use such as sustainable seafood advisory lists and certification. The two international systems are by the International Union for Conservation of Nature (IUCN) and The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). International systems IUCN Red List of Threatened Species The IUCN Red List of Threatened Species by the International Union for Conservation of Nature is the best known worldwide conse ...

States Of Germany
The Federal Republic of Germany is a federation and consists of sixteen partly sovereign ''states''. Of the sixteen states, thirteen are so-called area-states ('Flächenländer'); in these, below the level of the state government, there is a division into local authorities (counties and county-level cities) that have their own administration. Two states, Berlin and Hamburg, are city-states, in which there is no separation between state government and local administration. The state of Bremen (state), Bremen is a special case: the state consists of the cities of Bremen (city), Bremen, for which the state government also serves as the municipal administration, and Bremerhaven, which has its own local administration separate from the state government. It is therefore a mixture of a city-state and an area-state. Three states, Bavaria, Saxony, and Thuringia, use the appellation ("free state"); this title is merely stylistic and carries no legal or political significance (similar t ...

Bantam (chicken)
A bantam is any small variety of fowl, usually of chicken or domestic duck, duck. Most large chicken breeds and several breeds of duck have a bantam counterpart, which is much smaller than the standard-sized fowl, but otherwise similar in most or all respects. A List of true bantam chicken breeds, true bantam chicken is naturally small and has no large counterpart. Etymology The word ''bantam'' derives from the name of the Banten (town), seaport city of Bantam in western Java, Indonesia. European sailors restocking on live fowl for sea journeys found the small native breeds of chicken in Southeast Asia to be useful, and any such small poultry came to be known as a ''bantam''.

Chicken
The chicken (''Gallus gallus domesticus'') is a domesticated subspecies of the red junglefowl (''Gallus gallus''), originally native to Southeast Asia. It was first domesticated around 8,000 years ago and is now one of the most common and widespread domesticated animals in the world. Chickens are primarily kept for chicken as food, their meat and egg as food, eggs, though they are also kept as pets. As of 2023, the global chicken population exceeds 26.5 billion, with more than 50 billion birds produced annually for consumption. Specialized breeds such as broilers and laying hens have been developed for meat and egg production, respectively. A hen bred for laying can produce over 300 eggs per year. Chickens are social animals with complex vocalizations and behaviors, and cultural references to chickens, feature prominently in folklore, religion, and literature across many societies.
