A landrace is a local variety of a domesticated animal or plant species which has developed largely by natural processes, by adaptation to the natural and cultural environment in which it lives.
Our more specific description of a dog breed is: Breeds are products of breed clubs, not of nature. They are not a species. They do not represent the genetic diversity of the landrace population from which they were adopted. Breeds are sexually isolated descendants of a very small and select sample of individuals adopted from regionally located landrace populations. One definition of a landrace applied to both plants and animals is which has developed over a long period of time and as a result has adapted to the local natural environment in which it lives.. However, in other cases, formalizing a landrace may result in the genetic resource of a landrace being lost through crossbreeding. Landraces are distinct from ancestral wild species of modern stock, and from separate species or subspecies derived from the same ancestor as modern domestic stock. A landrace native to, or produced for a long time (e.g. 100 years or longer) within the agricultural system in which it is found is referred to as an autochthonous landrace, while an introduced one is termed an allochthonous landrace. However, in other cases, formalizing a landrace may result in the genetic resource of a landrace being lost through crossbreeding. Landraces are distinct from ancestral wild species of modern stock, and from separate species or subspecies derived from the same ancestor as modern domestic stock. Breeds of Livestock-American Landrace Swine. The various strains of Landrace swine are the descendants of the famous Danish Landrace hogs that were developed in Denmark. The development of the breed began in about 1895. It resulted from crossing the Large White hog from England with the native s The American Landrace is a medium to large breed of domestic pig, white in colour, with long bodies, fine hair, long snouts, and heavy, drooping ears. They are bred for pork production. The American Landrace derives from the Danish Landrace of 1895 Danish origin. The American Landrace is a long, lean, white pig with sixteen or seventeen ribs. The head is long and narrow and the ears large and heavy and hang forwards close to the snout. The back is only slightly arched or is nearly flat. The side is even and well-fleshed and the ham is plump but not over-fat. Landrace dogs have more variety in their appearance than do standardized dog breeds. An example of a dog landrace with a related standardized breed with a similar name is the collie. The Scotch Collie is a landrace, while the Rough Collie and the Border Collie are standardized breeds. However, in other cases, formalizing a landrace may result in the genetic resource of a landrace being lost through crossbreeding. Landraces are distinct from ancestral wild species of modern stock, and from separate species or subspecies derived from the same ancestor as modern domestic stock. A landrace is a domesticated, regional ecotype; a locally adapted, traditional variety of a domesticated species of animal or plant that has developed over time, through adaptation to its natural and cultural environment of agriculture and pastoralism, and due to isolation from other populations of the species. However, in other cases, formalizing a landrace may result in the genetic resource of a landrace being lost through crossbreeding. Landraces are distinct from ancestral wild species of modern stock, and from separate species or subspecies derived from the same ancestor as modern domestic stock. Landrace. A landrace is a local variety of a domesticated animal or plant species which has developed largely by natural processes, by adaptation to the natural and cultural environment in which it lives. When an animal landrace is codified as a pedigree breed without significant selective breeding to alter it, though often to lock in its defining traits, it is often referred to as a natural breed or traditional breed by breeder and fancier organisations.
