American Pekin Duck
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'', which roughly translates to "ten-pound duck", from which the American Pekin derives. In 1872, James E. Palmer of Sto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Duck Egg
Humans and human ancestors have scavenged and eaten animal eggs for millions of years. Humans in Southeast Asia had domesticated chickens and harvested their eggs for food by 1,500 BCE. The most widely consumed eggs are those of fowl, especially chickens. Eggs of other birds, including ostriches and other ratites, 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. Bird and reptile eggs consist of a protective eggshell, albumen ( egg white), and vitellus ( egg yolk), contained within various thin membranes. Egg yolks and whole eggs store significant amounts of protein and choline, and are widely used in cookery. Due to their protein content, the United States Department of Agriculture formerly categorized eggs as ''Meats'' within the Food Guide Pyramid (now MyPlate). Despite the nutritional value of eggs, there are some potential health issues ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Standard Of Perfection
The ''American Standard of Perfection'' is the official breed standard for the poultry fancy in North America. First published in 1874 by the American Poultry Association, the ''Standard of Perfection'' (commonly referred to as "the ''Standard''") classifies and describes the standard physical appearance, coloring and temperament for all recognized breeds of poultry, including chickens, ducks, turkeys, and geese. The current edition was published in 2015. Use The ''Standard'' is used by American Poultry Association judges at sanctioned poultry shows to judge poultry, and by those who participate in the competitive showing of selectively bred birds that conform to the standard, which led to the term "standard bred" poultry. History The first edition of the book listed 41 breeds, and today's versions have nearly 60. There are 19 classes of poultry recognized by the American Poultry Association. Eleven of these classes are devoted to chickens, of which six are classes of large bree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Entente Européenne D’Aviculture Et De Cuniculture

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 century, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Incubator (egg)
An incubator is a device simulating avian incubation by keeping 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 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. left, Réaumur's incubator Controlled scientific incubation required the accurate and repeatable measurement of temperature, such as the alcohol-based thermometer proposed by t ...

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 ma ...

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 and is a common livestock bird in many cultures. The Pekin duck is another livestock breed of importance, particularly in North America. Magret refers specifically to the breast of a mulard 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, which is made from the Pekin 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 ...

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 outp ...

Keel (bird Anatomy)
A keel or carina (plural 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. Without a keel a bird will not be able to fly. 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 class ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baby Duck
An infant or baby is the very young offspring of human beings. ''Infant'' (from the Latin word ''infans'', meaning 'unable to speak' or 'speechless') is a formal or specialised synonym for the common term ''baby''. The terms may also be used to refer to juveniles of other organisms. A newborn is, in colloquial use, an infant who is only hours, days, or up to one month old. 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. 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 learns to walk, they are called a toddler instead. Other uses In British English, an ''infant school'' is for children aged between four and seven. As a legal term, ''infancy'' is more lik ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, 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 duck rearing in ...
