American Landrace
The American Landrace is an American List of pig breeds, breed of domestic pig. It is white in color, with a long body, fine hair, a long snout and heavy, drooping ears. Like all landrace pigs, it derives from the Danish Landrace (pig), Danish Landrace. History The American Landrace derives from the Danish Landrace pig, Danish Landrace, which in turn derives from cross-breeding in the late nineteenth century between local Danish pigs and Large White (pig), Large White stock imported from Britain. In 1934 twenty-four of these pigs were imported from Denmark by the United States Department of Agriculture for cross-breeding and research purposes, with a condition that they not be used to create a purebred commercial stock. That restriction was lifted in 1949 and a breed association, the American Landrace Association, was established in 1950. The new breed was founded on stock that was either purebred Danish or had a small percentage of Poland China blood. To reduce inbreeding, thi ...

Danish Landrace Pig
The Danish Landrace, da, Hvid Dansk Landrace, italic=no, is a Danish breed of pig. It is of medium to large size, white in colour with a long body, fine hair, a long snout, and heavy drooping ears. There are two distinct varieties, the white (') and the piebald ('). History During the second half of the nineteenth century, Denmark became a major supplier of bacon to the United Kingdom: exports grew from 1000 tons per year in 1850 to in 1900; they grew still further in the twentieth century, reaching in 1932. From about 1865, and particularly between 1879 and 1896, breeding stock of the British Large White or Yorkshire breed was imported and cross-bred with local animals to supply the bacon trade. The cross of a Large White boar with a sow of the traditional Jutland breed was found to be particularly successful. In 1896 the Danish government drew up a national plan for pig production, under which the Large White x Jutland hybrid would become a new breed, the Danish Land ...

Domestic Pig
The pig (''Sus domesticus''), often called swine, hog, or domestic pig when distinguishing from other members of the genus '' Sus'', is an omnivorous, domesticated, even-toed, hoofed mammal. It is variously considered a subspecies of ''Sus scrofa'' (the wild boar or Eurasian boar) or a distinct species. The pig's head-plus-body length ranges from , and adult pigs typically weigh between , with well-fed individuals even exceeding this range. The size and weight of hogs largely depends on their breed. Compared to other artiodactyls, a pig's head is relatively long and pointed. Most even-toed ungulates are herbivorous, but pigs are omnivores, like their wild relative. Pigs grunt and make snorting sounds. When used as livestock, pigs are farmed primarily for the production of meat, called pork. A group of pigs is called a ''passel'', a ''team'', or a ''sounder''. The animal's bones, hide, and bristles are also used in products. Pigs, especially miniature breeds, are kept as pets ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landrace Pigs
The term Landrace pig or Landrace swine refers to any of a group of standardized breeds of domestic pig, and in this context the word ''Landrace'' is typically capitalized. The original breed by this name was the Danish Landrace pig, from which the others were derived through development and crossbreeding. The breed was so-named because the foundation stock of the Danish Landrace were specimens from the local, free-breeding, non-pedigreed stock of swine, i.e. the regional landrace native to Denmark. The modern breeds are not themselves landraces, since they are formal breeds maintained through selective breeding rather than natural selection. The establishment and spread of the Danish breed gave the word ''landrace'' to the English language (it had already existed in Danish, German, Dutch and some other Germanic languages). Based on the ''Random House Dictionary''. Sources from the mid-20th century often mean the Danish Landrace swine in particular when referring to "Landrace" ...

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 ' ...

Large White (pig)
The Large White is a British breed of domestic pig. It derives from the old Yorkshire breed from the county of Yorkshire, in northern England. History First recognised in 1868, the breed is the progenitor of the American Yorkshire in North America. Characteristics The Large White is a big, white pig, with erect ears and a slightly dished face. Use The Large White is one of the most numerous of all pig breeds, widely used in crossbreeding for intensive pig farming Intensive pig farming, also known as pig factory farming, is the primary method of pig production, in which grower pigs are housed indoors in group-housing or straw-lined sheds, whilst pregnant sows are housed in gestation crates or pens and g ... around the world.

Breed Association
Breed clubs are associations or clubs with activities centered on a single, specific breed of a particular species of domesticated animal. The purpose of the association will vary with the species of animal and the goals and needs of the members of the association. Breed associations or clubs may vary in their goals, activities and nomenclature from country to country, even for the same breed. Most domesticated animals, whether they are agricultural animals such as cattle, llamas, poultry, sheep and pigs, or companion animals such as pigeons, horses, cats and dogs, have breed clubs associated with the breed. Purpose In general, breed clubs and associations create a written definition of the breed (called a breed standard) for the breed with which the organization is associated. Breed clubs also maintain important records, and provide members with information. Many breed associations also have a social component, organising various activities such as shows. In addition, they may r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poland China
The Poland China is an American breed of domestic pig. It was first bred in Warren County in Ohio, in the American Midwest. Its origins lie in a small number of pigs of Chinese type bought in 1816, which were cross-bred with a variety of breeds of European origin including the Berkshire. It was bred as a lard pig, and is among the largest of all pig breeds. It is the oldest American breed of swine. History The origins of the Poland China lie in the purchase in Philadelphia in 1816 by John Wallace, a trustee of the Shaker Society of Union Village in Warren County, Ohio, of four pigs of the breed or type known as Big China; it is possible that they were in fact of the now-extinct Bedford breed. Three sows and a boar were brought to the village of Union, where Shaker farmers cross-bred them with local pigs of the types known as Russia or Byfield, both large pale-skinned pigs. Further crossing with other breeds of European origin including the British Berkshire and the Irish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inbreeding
Inbreeding is the production of offspring from the mating or breeding of individuals or organisms that are closely related genetically. By analogy, the term is used in human reproduction, but more commonly refers to the genetic disorders and other consequences that may arise from expression of deleterious or recessive traits resulting from incestuous sexual relationships and consanguinity. Animals avoid incest only rarely. Inbreeding results in homozygosity, which can increase the chances of offspring being affected by recessive traits. In extreme cases, this usually leads to at least temporarily decreased biological fitness of a population (called inbreeding depression), which is its ability to survive and reproduce. An individual who inherits such deleterious traits is colloquially referred to as ''inbred''. The avoidance of expression of such deleterious recessive alleles caused by inbreeding, via inbreeding avoidance mechanisms, is the main selective reason for outcrossin ...
