Ermellinata Di Rovigo
The Ermellinata di Rovigo is a modern Italian breed of dual-purpose chicken. It originates in the city of Rovigo in the Veneto region of north-eastern Italy, from which it takes its name. It was created between 1959 and 1965, principally from Sussex and Rhode Island Red parentage. History The Ermellinata di Rovigo was created between 1959 and 1965 at the Stazione Sperimentale di Pollicoltura, or experimental chicken breeding centre, of Rovigo, in the Veneto. It was conceived as a dual-purpose breed, and based on Rhode Island Red and Sussex stock. It broadly resembles a Light Sussex, with the difference that it has yellow skin and legs, which are traditionally preferred by Italian consumers of chicken meat. A standard for the breed was published by the now-defunct Associazione Nazionale Allevatori Specie Avicole, or national association of breeders of avian species, in the latter part of the 20th century, and is published for historic interest on the website of the Federa ...

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] |
Padovana Chicken
The Padovana or Padovana dal gran ciuffo () is an ancient Italian list of chicken breeds, breed of small crested and bearded chicken. It originates in, and is named for, the city and surrounding Province of Padua, province of Padua, in the Veneto region of north-eastern Italy. Despite continuing discussion surrounding its true origins, it is recognised in Italy as an indigenous Italian breed. History The early history of the Padovana is unclear, and the subject of continuing discussion, as is its relationship to the Polish (chicken), Polish and the Dutch crested () and Dutch bearded crested () breeds, which are variously considered to have originated in the Netherlands, in Poland, in Russia, or elsewhere. It is often reported that the Padovana was brought from Poland to Italy by the "Marquis" Giovanni Dondi dell'Orologio (1330–88). However the Dondi who was ennobled was the soldier Francesco Dondi, created Marquis by King John III Sobieski in 1676; no journey to or contact ...

New Hampshire (chicken)
The New Hampshire Red or New Hampshire is an American breed of chicken. It was developed in the early twentieth century in the state of New Hampshire by selective breeding of Rhode Island Red stock; no other breed was involved. It is fast-growing, early-maturing, quick-feathering, and yields a meaty carcase. Mature birds are a light or medium red in color; they may fade in sunlight. History The New Hampshire Red was developed over a period of about thirty years in the early twentieth century in the state of New Hampshire, partly by farmers in the state and partly through research conducted at the New Hampshire Agricultural Experiment Station at Durham. Birds of the Rhode Island Red breed were selectively bred for rapid growth and rapid feathering, with an emphasis on meat production; no other breed was involved. Color was not a criterion for selection, and the resulting birds were of a somewhat lighter red than the original Rhode Island stock. The New Hampshire Red was admitt ...

Sex Link
Sex-links are crossbred chickens whose color at hatching is differentiated by sex, thus making chick sexing an easier process. Sex-links come in several varieties. As hybrids of laying or dual-purpose breeds infused with extra vigor via heterosis, sex-links can be extremely good egg-layers which often produce 300 eggs a year or more depending on the quality of care and feed. The color of their eggs vary according to the mix of breeds, and blue-green eggs are possible. Chicks of a single breed that are similarly sex-linked are called autosex chickens, a term developed to differentiate between sex linkage in purebred chickens versus sex linkage in crossbreeds. Sex-link types Many common varieties are known as the black sex-link (also called black stars) and the red sex-link (also called red stars). More specific variety names are common as well. * Black sex-link like "Black rocks" are a cross between unique specially bred hybrid strains of Rhode Island Red rooster (but any non-w ...

Leghorn (chicken)
The Leghorn (, ; it, Livorno, italic=no or Livornese) is a breed of chicken originating in Tuscany, in central Italy. Birds were first exported to North America in 1828 from the Tuscan port city of Livorno, on the western coast of Italy. They were initially called "Italians", but by 1865 the breed was known as "Leghorn", the traditional anglicisation of "Livorno". The breed was introduced to Britain from the United States in 1870. White Leghorns are commonly used as layer chickens in many countries of the world. Other Leghorn varieties are less common. History The origins of the Leghorn are not clear; it appears to derive from light breeds originating in rural Tuscany. The name comes from Leghorn, the traditional anglicisation of Livorno, the Tuscan port from which the first birds were exported to North America. The date of the first exports is variously reported as 1828, "about 1830" and 1852. They were initially known as "Italians"; they were first referred to as "Leghor ...

Cross-breeding
A crossbreed is an organism with purebred parents of two different breeds, varieties, or populations. ''Crossbreeding'', sometimes called "designer crossbreeding", is the process of breeding such an organism, While crossbreeding is used to maintain health and viability of organisms, irresponsible crossbreeding can also produce organisms of inferior quality or dilute a purebred gene pool to the point of extinction of a given breed of organism. 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 ' ...

Biodiversity
Biodiversity or biological diversity is the variety and variability of life on Earth. Biodiversity is a measure of variation at the genetic (''genetic variability''), species (''species diversity''), and ecosystem (''ecosystem diversity'') level. Biodiversity is not distributed evenly on Earth; it is usually greater in the tropics as a result of the warm climate and high primary productivity in the region near the equator. Tropical forest ecosystems cover less than 10% of earth's surface and contain about 90% of the world's species. Marine biodiversity is usually higher along coasts in the Western Pacific, where sea surface temperature is highest, and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity. Biodiversity generally tends to cluster in hotspots, and has been increasing through time, but will be likely to slow in the future as a primary result of deforestation. It encompasses the evolutionary, ecological, and cultural ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robusta Maculata
The Robusta Maculata is a recent dual-purpose breed of chicken originating in the city of Rovigo in the Veneto region of north-eastern Italy. It was created between 1959 and 1965, by cross-breeding Buff Orpingtons with the commercial strain known in Italy as "White America". History The Robusta Maculata was created between 1959 and 1965 at the Stazione Sperimentale di Pollicoltura, or experimental chicken breeding centre, of Rovigo, in the Veneto. It was conceived as a dual-purpose breed, and derived from crossing the Buff Orpington with a commercial strain widely raised in Veneto in the 20th century, known in Italy as "White America". The White America is believed to have been based on mutant white Barnevelders, with contributions from White Leghorn, Rhode Island White and White Rock stock; in early 2012 it was no longer considered a breed. A standard for the Robusta Maculata was published by the now defunct Associazione Nazionale Allevatori Specie Avicole, or national a ...

List Of 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 American B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
