White Pekin
The Pekin or White Pekin is an American breed of domestic duck, raised primarily for meat. It derives from birds brought to the United States from China in the nineteenth century, and is now bred in many parts of the world. It is often known as the American Pekin to distinguish it from the German Pekin, a distinct and separate breed which derives from the same Chinese stock but has different breeding. Many of these ducks were reared on Long Island, New York, in the late nineteenth and early twentieth centuries, from which the breed derived its name Long Island Duck. History The mallard was domesticated in China some 3000 years ago, and possibly much earlier. Force-feeding of ducks is documented from the tenth century, under the Five Dynasties. The Chinese were sophisticated breeders of ducks; among several breeds they created was one named ''shi-chin-ya-tze'' (十斤鴨子), which roughly translates to "ten-pound duck", from which the American Pekin derives. In 1872, James ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Duck Egg
Humans and other hominids have consumed eggs for millions of years. The most widely consumed eggs are those of fowl, especially chickens. People in Southeast Asia began harvesting chicken eggs for food by 1500 BCE. Eggs of other birds, such as ducks and ostriches, are eaten regularly but much less commonly than those of chickens. People may also eat the eggs of reptiles, amphibians, and fish. Fish eggs consumed as food are known as roe or caviar. Hens and other egg-laying creatures are raised throughout the world, and mass production of chicken eggs is a global industry. In 2009, an estimated 62.1 million metric tons of eggs were produced worldwide from a total laying flock of approximately 6.4 billion hens. There are issues of regional variation in demand and expectation, as well as current debates concerning methods of mass production. In 2012, the European Union banned battery husbandry of chickens.

New York City
New York, often called New York City (NYC), is the most populous city in the United States, located at the southern tip of New York State on one of the world's largest natural harbors. The city comprises five boroughs, each coextensive with a respective county. The city is the geographical and demographic center of both the Northeast megalopolis and the New York metropolitan area, the largest metropolitan area in the United States by both population and urban area. New York is a global center of finance and commerce, culture, technology, entertainment and media, academics, and scientific output, the arts and fashion, and, as home to the headquarters of the United Nations, international diplomacy. With an estimated population in 2024 of 8,478,072 distributed over , the city is the most densely populated major city in the United States. New York City has more than double the population of Los Angeles, the nation's second-most populous city. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poultry Show
A poultry show is a specific subset of a livestock show that involves the exhibition and competition of exhibition poultry, which may include chickens, domestic ducks, domestic geese, domestic guineafowl and domestic turkey. Domestic pigeon are also exhibited but not universally considered poultry. As well as being independent events, they are also sometimes held in conjunction with agricultural shows. Preparation Significant effort is put into exhibiting poultry. Birds are trained for the cages used at shows, and washed and manicured in preparation for an event. History The first poultry show in the United Kingdom was in 1845 in London. The exhibition of poultry was promoted as an alternative to cock fighting in the United Kingdom following the banning of such activities in 1849. The first poultry standard in the world was produced in 1865, the British Poultry Standard. The height of the poultry showing in the United Kingdom was during the late 19th and early 20th centu ...

Incubator (egg)
An incubator is a device simulating avian incubation by keeping egg (biology), eggs warm at a particular temperature range and in the correct humidity with a turning mechanism to hatch them. The common names of the incubator in other terms include ''breeding / hatching machines'' or ''hatchers'', ''setters'', and ''egg breeding / equipment''. History The Egyptians had a method of incubating in 400 BC, using a Egyptian egg oven, cylindrical building or oven that had a fire at the bottom. The eggs that were incubating were placed on an inverted cone that was partially covered in ash. The eggs were placed in a woven basket that sat on top of the ashes. The building also had a roof that allowed smoke to escape, but it kept the rain out. Egyptian egg ovens are typically brick structures in a pyramidal shape, with two internal chambers. file:Method for incubation of poultry eggs Wellcome L0072129.jpg, left, Réaumur's incubator Controlled scientific incubation required the accur ...

Broodiness
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 mal ...

Duck Fat
In cooking and gastronomy, duck or duckling is the meat of several species of bird in the family Anatidae, found in both fresh and salt water. Duck is eaten in many cuisines around the world. It is a high-fat, high-protein meat rich in iron. Duckling nominally comes from a juvenile animal, but may be simply a menu name. One species of freshwater duck, the mallard, has been domesticated; the domesticated duck is a common livestock bird in a variety of cultures. The Pekin duck is another livestock breed of importance, particularly in North America. Magret refers specifically to the breast of a moulard or Muscovy (or Barbary) duck that has been force fed to produce foie gras. Duck meat Duck is particularly predominant in the Chinese cuisine—a popular dish is Peking duck. Duck meat is commonly eaten with scallions, cucumbers and hoisin sauce wrapped in a small spring pancake made of flour and water or a soft, risen bun known as gua bao. In Cantonese cuisine, the r ...

Feed Conversion Ratio
In animal husbandry, feed conversion ratio (FCR) or feed conversion rate is a ratio or rate measuring of the efficiency with which the bodies of livestock convert animal feed into the desired output. For dairy cows, for example, the output is milk, whereas in animals raised for meat (such as beef cows,Dan Shike, University of IllinoiBeef Cattle Feed Efficiency/ref> pigs, chickens, and fish) the output is the flesh, that is, the body mass gained by the animal, represented either in the final mass of the animal or the mass of the dressed output. FCR is the mass of the input divided by the output (thus mass of feed per mass of milk or meat). In some sectors, feed efficiency, which is the output divided by the input (i.e. the inverse of FCR), is used. These concepts are also closely related to efficiency of conversion of ingested foods (ECI). Background Feed conversion ratio (FCR) is the ratio of inputs to outputs; it is the inverse of "feed efficiency" which is the ratio of outpu ...

Keel (bird Anatomy)
A ''keel'' or ''carina'' (: carinae) in bird anatomy is an extension of the sternum (breastbone) which runs axially along the midline of the sternum and extends outward, perpendicular to the plane of the ribs. The keel provides an anchor to which a bird's wing muscles attach, thereby providing adequate leverage for flight. Not all birds have keels; in particular, some flightless birds lack a keel structure. Some flightless birds have a keel, such as the penguin; but in the penguin's case, its wings are too small for its body, so flight would require flapping its wings too fast to be practical. Historically, the presence or absence of a pronounced keel structure was used as a broad classification of birds into two orders: Carinatae (from ''carina'', "keel"), having a pronounced keel; and ratites (from ''ratis'', "raft"referring to the flatness of the sternum), having a subtle keel structure or lacking one entirely. However, this classification has become disused as evolutio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baby Duck
In common terminology, a baby is the very young offspring of adult human beings, while infant (from the Latin word ''infans'', meaning 'baby' or 'child') is a formal or specialised synonym. The terms may also be used to refer to juveniles of other organisms. A newborn is, in colloquial use, a baby who is only hours, days, or weeks old; while in medical contexts, a newborn or neonate (from Latin, ''neonatus'', newborn) is an infant in the first 28 days after birth (the term applies to premature, full term, and postmature infants). Infants born prior to 37 weeks of gestation are called "premature", those born between 39 and 40 weeks are "full term", those born through 41 weeks are "late term", and anything beyond 42 weeks is considered "post term". Before birth, the offspring is called a fetus. The term ''infant'' is typically applied to very young children under one year of age; however, definitions may vary and may include children up to two years of age. When a human child ...

Aylesbury (duck)
The Aylesbury duck is a breed of domesticated duck, bred mainly for its meat and appearance. It is a large duck with pure white plumage, a pink bill, orange legs and feet, an unusually large Keel (bird), keel, and a horizontal stance with its body parallel to the ground. The precise origins of the breed are unclear, but raising white ducks became popular in Aylesbury, Buckinghamshire, England, in the 18th century owing to the demand for white feathers as a filler for quilts. Over the 19th century selective breeding for size, shape and colour led to the Aylesbury duck. Duck rearing became a major industry in Aylesbury in the 19th century. The ducks were bred on farms in the surrounding countryside. Fertilised eggs were brought into the town's "Duck End", where local residents would rear the ducklings in their homes. The opening of a railway to Aylesbury in 1839 enabled cheap and quick transport to the markets of London, and duck rearing became highly profitable. By the 1860s the du ...

Cross-bred
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 ...
