African Goose
The African goose is a breed of domestic goose derived from the wild swan goose (''Anser cygnoides''). Despite the name African goose, they are not actually from Africa and are descended from the Chinese goose. Origin Its origin has been attributed to many different continents - it arrived in Europe in the late 1700s and North America from ships that traveled around the world in the mid 1800s. Two origin theories persist for the fowl: the first purporting that African is the result of crosses of swan goose and Chinese goose, while the other asserts that it is a direct derivation of the swan goose, and its unique traits are simply the result of selective breeding. Whichever is the case, the African goose has existed as a distinct breed since the middle of the nineteenth century or before, and was admitted to the American Poultry Association's Standard of Perfection in 1874. The African goose has many physical similarities, such as shape and coloration, to the Lion Head Geese in C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Breed
A breed is a specific group of domestic animals having homogeneous appearance (phenotype), homogeneous behavior, and/or other characteristics that distinguish it from other organisms of the same species. In literature, there exist several slightly deviating definitions. Breeds are formed through genetic isolation and either natural adaptation to the environment or selective breeding, or a combination of the two. Despite the centrality of the idea of "breeds" to animal husbandry and agriculture, no single, scientifically accepted definition of the term exists. A breed is therefore not an objective or biologically verifiable classification but is instead a term of art amongst groups of breeders who share a consensus around what qualities make some members of a given species members of a nameable subset. Another point of view is that a breed is consistent enough in type to be logically grouped together and when mated within the group produce the same type. When bred together, ind ...

Domestic Goose
A domestic goose is a goose that humans have domesticated and kept for their meat, eggs, or down feathers. Domestic geese have been derived through selective breeding from the wild greylag goose (''Anser anser domesticus'') and swan goose (''Anser cygnoides domesticus''). Origins In Europe, northern Africa, and western Asia, the original domesticated geese are derived from the greylag goose (''Anser anser''). In eastern Asia, the original domesticated geese are derived from the swan goose (''Anser cygnoides''); these are commonly known as Chinese geese. Both have been widely introduced in more recent times, and modern flocks in both areas (and elsewhere, such as Australia and North America) may consist of either species or hybrids between them. Chinese geese may be readily distinguished from European geese by the large knob at the base of the bill, though hybrids may exhibit every degree of variation between the two species. Charles Darwin remarked in ''The Variation of Animals ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swan Goose
The swan goose (''Anser cygnoides'') is a large goose with a natural breeding range in inland Mongolia, northernmost China, and the Russian Far East. It is migratory and winters mainly in central and eastern China. Vagrant birds are encountered in Japan and Korea (where it used to winter in numbers when it was more common), and more rarely in Kazakhstan, Laos, coastal Siberia, Taiwan, Thailand and Uzbekistan. While uncommon in the wild, this species has been domesticated. Introduced and feral populations of its domestic breeds occur in many places outside its natural range. The wild form is also kept in collections, and escapes are not unusual amongst feral flocks of other ''Anser'' and ''Branta'' geese. Description The swan goose is large and long-necked for its genus, wild birds being long (the longest ''Anser'' goose) and weighing or more (the second-heaviest ''Anser'', after the greylag goose, ''A. anser''). The sexes are similar, although the male is larger, with a prop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chinese Goose
The Chinese goose (''Anser cygnoides domesticus'') is an international breed of domestic goose, known by this name in Europe and in North America. History Unlike the majority of goose breeds, which derive from ''Anser anser'', the Chinese goose belongs to the knob geese, which derive from ''Anser cygnoides'' and are characterised by a prominent basal knob on the upper side of the bill. As the name suggests, it is believed to have originated in China, where there are more than twenty different breeds of knob goose. It was seen in Britain from the early eighteenth century if not before, and was present in the United States in the latter part of that century – George Washington is believed to have kept some on his plantation at Mount Vernon. It was included in the first ''Standard of Perfection'' of the American Poultry Association in 1874. In the twenty-first century it is an endangered breed: it is reported to DAD-IS by seven countries – Australia, Lithuania, Moldova ...

Selective Breeding
Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together. Domesticated animals are known as breeds, normally bred by a professional breeder, while domesticated plants are known as varieties, cultigens, cultivars, or breeds. Two purebred animals of different breeds produce a crossbreed, and crossbred plants are called hybrids. Flowers, vegetables and fruit-trees may be bred by amateurs and commercial or non-commercial professionals: major crops are usually the provenance of the professionals. In animal breeding, techniques such as inbreeding, linebreeding, and outcrossing are utilized. In plant breeding, similar methods are used. Charles Darwin discussed how selective breeding had been successful in producing change over time in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Poultry Association
The American Poultry Association (APA) is the oldest poultry organization in the North America. It was founded in 1873, and incorporated in Indiana in 1932. The first American poultry show was held in 1849, and the APA was later formed in response to the burgeoning need for an overseeing body to set standards for poultry breeds and to administer judging. A year after its foundation, the Association published the first ''American Standard of Perfection'', which to this day is the most widely used and respected handbook on poultry breed standards. The APA continues to publish and expand the ''Standard'', and aims to promote all aspects of poultry fancy by certifying official judges, sponsoring shows, fostering youth participation, and advocating for its members, in both the U.S. and Canada. The Poultry Standard of Perfection Once the APA was formed in 1849, they made it their first order of business to create a standard for American poultry breeds. Six members from the original m ...

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] |
Dewlap
A dewlap is a longitudinal flap of skin or similar flesh that hangs beneath the lower jaw or neck of many vertebrates. More loosely, it can be various similar structures in the neck area, such as those caused by a double chin or the submandibular vocal sac of a frog. More generally, it can be any hanging mass of skin, such as a fold of loose skin on an elderly person's neck, or the wattle of a bird. Dewlaps can be considered as a ''caruncle'', defined as "a small, fleshy excrescence that is a normal part of an animal's anatomy". Etymology The word is first attested in the mid 1300s as ''dewelappe'' ("fold of skin that hangs from the throat of oxen and kine"), from ''lappe'' ("loose piece", from Old English ), but the first element ''*dew(e)-'' is of nebulous origin and meaning; it probably was altered by folk etymology with "dew". Old English had ''fræt-læppa'' in the aforementioned sense (and Middle English ''fresh-lappe''). There also seems to be a cognate to Danish dial ...

Toulouse Goose
The Toulouse is a French breed of large domestic goose, originally from the area of Toulouse in south-western France. Two types are recognised: a heavy industrial type with dewlaps, the french: Oie de Toulouse à bavette, italic=no; and a slightly lighter agricultural type without dewlaps, the french: Oie de Toulouse sans bavette, italic=no. Both types are large, with weights of up to . Birds bred in the United Kingdom and United States exclusively for showing may be still larger, and have a somewhat different conformation. History The history of the Toulouse is a long one, going back at least to 1555. It was reared for meat and for foie gras. Some were brought to the United Kingdom in the 1840s by Edward Smith-Stanley, 13th Earl of Derby, who was at that time president of the Zoological Society of London. There it was bred for considerably greater weight; the British breed standard dates from 1865. Some of these heavier British birds were later exported to North America. ...

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] |
