Broody
Broodiness is the action or behavioral tendency to sit on a clutch of eggs to incubate them, often requiring the non-expression of many other behaviors including feeding and drinking.Homedes Ranquini, J. y Haro-García, F. Zoogenética. 1ra. edición, 1958, (La Habana, 1967 Ed. Revolucionaria) Being broody has been defined as "Being in a state of readiness to brood eggs that is characterized by cessation of laying and by marked changes in behavior and physiology". . Broodiness is usually associated with female birds, although males of some bird species become broody and some non-avian animals also show broodiness. In wild birds In wild birds, egg incubation is a normal and essential phase in the process of reproduction, and in many families of birds, e.g. pigeons, the eggs are incubated by both male and female parents. Broodiness in males In all species of phalaropes, the males become broody rather than the female. The females leave the nest after finishing laying to let the ma ...

Prolactin
Prolactin (PRL), also known as lactotropin, is a protein best known for its role in enabling mammals to produce milk. It is influential in over 300 separate processes in various vertebrates, including humans. Prolactin is secreted from the pituitary gland in response to eating, mating, estrogen treatment, ovulation and nursing. It is secreted heavily in pulses in between these events. Prolactin plays an essential role in metabolism, regulation of the immune system and pancreatic development. Discovered in non-human animals around 1930 by Oscar Riddle and confirmed in humans in 1970 by Henry Friesen, prolactin is a peptide hormone, encoded by the ''PRL'' gene. In mammals, prolactin is associated with milk production; in fish it is thought to be related to the control of water and salt balance. Prolactin also acts in a cytokine-like manner and as an important regulator of the immune system. It has important cell cycle-related functions as a growth-, differentiating- and anti ...

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 ...

Geese
A goose (plural, : geese) is a bird of any of several waterfowl species in the family (biology), family Anatidae. This group comprises the genera ''Anser (bird), Anser'' (the grey geese and white geese) and ''Branta'' (the black geese). Some other birds, mostly related to the shelducks, have "goose" as part of their names. More distantly related members of the family Anatidae are swans, most of which are larger than true geese, and ducks, which are smaller. The term "goose" may refer to either a male or female bird, but when paired with "gander", refers specifically to a female one (the latter referring to a male). Young birds before fledging are called goslings. The List of collective nouns, collective noun for a group of geese on the ground is a gaggle; when in flight, they are called a skein, a team, or a wedge; when flying close together, they are called a plump. Etymology The word "goose" is a direct descendant of,''*ghans-''. In Germanic languages, the root gave Old E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turkeys
The turkey is a large bird in the genus ''Meleagris'', native to North America. There are two extant turkey species: the wild turkey (''Meleagris gallopavo'') of eastern and central North America and the ocellated turkey (''Meleagris ocellata'') of the Yucatán Peninsula in Mexico. Males of both turkey species have a distinctive fleshy wattle, called a snood, that hangs from the top of the beak. They are among the largest birds in their ranges. As with many large ground-feeding birds (order Galliformes), the male is bigger and much more colorful than the female. Native to North America, the wild species was bred as domesticated turkey by indigenous peoples. It was this domesticated turkey that later reached Eurasia, during the Columbian exchange. In English, "turkey" probably got its name from the domesticated variety being imported to Britain in ships coming from the Turkish Levant via Spain. The British at the time therefore associated the bird with the country Turkey an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phasianus Colchicus
The common pheasant (''Phasianus colchicus'') is a bird in the pheasant family (Phasianidae). The genus name comes from Latin ''phasianus'', "pheasant". The species name ''colchicus'' is Latin for "of Colchis" (modern day Georgia), a country on the Black Sea where pheasants became known to Europeans. Although ''Phasianus'' was previously thought to be closely related to the genus ''Gallus'', the genus of junglefowl and domesticated chickens, recent studies show that they are in different subfamilies, having diverged over 20 million years ago. It is native to Asia and parts of Europe like the northern foothills of the Caucasus and the Balkans. It has been widely introduced elsewhere as a game bird. In parts of its range, namely in places where none of its relatives occur such as in Europe, where it is naturalised, it is simply known as the "pheasant". Ring-necked pheasant is both the name used for the species as a whole in North America and also the collective name for a number o ...

Quails
Quail is a collective name for several genera of mid-sized birds generally placed in the order Galliformes. The collective noun for a group of quail is a flock, covey, or bevy. Old World quail are placed in the family Phasianidae, and New World quail are placed in the family Odontophoridae. The species of buttonquail are named for their superficial resemblance to quail, and form the family Turnicidae in the order Charadriiformes. The king quail, an Old World quail, often is sold in the pet trade, and within this trade is commonly, though mistakenly, referred to as a "button quail". Many of the common larger species are farm-raised for table food or egg consumption, and are hunted on game farms or in the wild, where they may be released to supplement the wild population, or extend into areas outside their natural range. In 2007, 40 million quail were produced in the U.S. New World *Genus ''Callipepla'' **Scaled quail, (commonly called blue quail) ''Callipepla squamata'' **E ...

Silkie
The Silkie (also known as the Silky or Chinese silk chicken) is a breed of chicken named for its atypically fluffy plumage, which is said to feel like silk and satin. The breed has several other unusual qualities, such as black skin and bones, blue earlobes, and five toes on each foot, whereas most chickens only have four. They are often exhibited in poultry shows, and also appear in various colors. In addition to their distinctive physical characteristics, Silkies are well known for their calm, friendly temperament. It is among the most docile of poultry. Hens are also exceptionally broody, and care for young well. Although they are fair layers themselves, laying only about three eggs a week, they are commonly used to hatch eggs from other breeds and bird species due to their broody nature. History It is unknown exactly where or when these fowl with their singular combination of attributes first appeared, but the most well documented point of origin is ancient China. Other pla ...

Cornish (chicken)
The Indian Game is a British breed of game chicken, now reared either for meat or show. It originated in the early nineteenth century in the counties of Cornwall and Devon in south-west England. It is a heavy, muscular bird with an unusually broad breast; the eggs are brown. In the United States the name was changed in the early twentieth century to Cornish. A white variant, the White Cornish, was developed there at about the same time, and is much used in modern industrial chicken meat production in many parts of the world, either for cross-breeding to produce hybrid broilers, or to produce fast-growing " game hens". History The breed was developed by Sir Walter Gilbert, of Bodmin in Cornwall, in about 1820. It was intended to be a gamecock, but had no aptitude for cockfighting. It is recognised as "Indian Game" in Australia, by the Poultry Club of Great Britain in the United Kingdom, and by the Entente Européenne in Europe. In the United States the name was change ...

Cochin Chicken
The Cochin is a breed of large domestic chicken. It derives from large feather-legged chickens brought from China to Europe and North America in the 1840s and 1850s. It is reared principally for exhibition. It was formerly known as Cochin-China. History Like the Brahma, the Cochin derives from very large feather-legged chickens brought from China to Europe and North America in the 1840s and 1850s. These were at first known as "Shanghai" birds, and later as "Cochin-Chinas". The large size and striking appearance of these birds contributed to a sudden large increase of interest in poultry-breeding in Western countries, sometimes described as "hen fever". The Cochin was included in the first edition of the ''Standard of Excellence in Exhibition Poultry'', prepared by William Bernhardt Tegetmeier for the first Poultry Club of Great Britain in 1865. The colours described are buff, black, cinnamon, grouse, lemon, partridge, silver buff, silver cinnamon, and white. Bantam Cochins ...

Brood Patch
A brood patch is a patch of featherless skin on the underside of birds during the nesting season. Feathers act as inherent insulators, and prevent efficient incubation. Birds have solved this evolutionary dilemma by developing dedicated brood patches. This patch of skin is well supplied with blood vessels at the surface, enabling heat transfer to the eggs when incubating. In most species, the feathers in the region shed automatically, but ducks and geese may pluck and use their feathers to line the nest. Feathers regrow sooner after hatching in precocial birds than for those that have altricial young. Upon settling on a nest, birds will shift in a characteristic side to side manner to ensure full contact of the brood patch with eggs or young. The positions of brood patches can vary. Many have a single brood patch in the middle of the belly, while some shorebirds have one patch on each side of the belly. Gulls and Galliformes may have three brood patches. Pelicans, penguins, boobi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Capon
A capon (from la, cāpō, genitive ''cāpōnis'') is a cockerel (rooster) that has been castrated or neutered, either physically or chemically, to improve the quality of its flesh for food, and, in some countries like Spain, fattened by forced feeding. History The origins of caponised chickens are contested. They were known in ancient China as well as in ancient Greece and ancient Rome. An early record of caponisation is found under the Roman Republic: the Lex Faunia of 162 BC forbade fattening hens to conserve grain rations, so the Romans instead castrated roosters, which resulted in a doubling of size. It was also practiced later throughout medieval times, with gastronomic texts describing capons as preferred poultry since the ordinary fowl of the farmyard was regarded as peasant fare and "popular malice crediting monks with a weakness for capons." France is internationally renowned for maintaining a strong caponisation tradition with widespread and established industr ...
