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 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 conservatio ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extensive Management
Extensive farming or extensive agriculture (as opposed to intensive farming) is an Agriculture production system that uses small inputs of labour, fertilizers, and capital, relative to the land area being farmed. Systems Extensive farming is 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 labor are high. Nomadic herding is an extreme example of extensive farming, where herders move their animals to use feed from occasional sunlight. Geography Extensive farming is found in the mid-latitude sections of most continents, 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.

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.

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] |

Bantam (chicken)
A bantam is any small variety of fowl, usually of chicken or 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 true bantam chicken is naturally small and has no large counterpart. Etymology The word ''bantam'' derives from the name of the 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 junglefowl species, with attributes of wild species such as the grey and the Ceylon junglefowl that are originally from Southeastern Asia. Rooster or cock is a term for an adult male bird, and a younger male may be called a cockerel. A male that has been castrated is a capon. An adult female bird is called a hen and a sexually immature female is called a pullet. Humans now keep chickens primarily as a source of food (consuming both their meat and eggs) and as pets. Traditionally they were also bred for cockfighting, which is still practiced in some places. Chickens are one of the most common and widespread domestic animals, with a total population of 23.7 billion , up from more than 19 billion in 2011. There are more chickens in the world than any other bird. There are numerous cultural references to chickens – in myth, folklore and religion, and in language and literature. Genetic studies have pointed to mult ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Auto-sexing
Auto-sexing breeds of poultry are those in which the sex of newly-hatched chicks can be determined from the colour and markings of the down. Some breeds of chicken, of goose and of domestic pigeon have this characteristic. The idea of such a breed is due to Reginald Punnett, who created the first auto-sexing chicken breed, the Cambar, at the Genetical Institute in Cambridge in 1928. Mechanism Unlike sex-linked hybrids, such as 'red sex-links' or 'black sex-links', the Legbar is an auto-sexing breed. Several other auto-sexing breeds or auto-sexing varieties of breeds exist, such as Plymouth Rock, Bielefelder Kennhuhn, Niederrheiner, and Norwegian Jærhøns. Most breeds that end with -bar, such as Welbar, Rhodebar, Brussbar or Wybar, are auto-sexing as well. The importance that auto-sexing plays in the Legbar breed is also reflected in the fact that, next to a standards for the adult birds, the down colour and patterns are also standardised. Day-old male chicks ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
