Dutch Landrace Goat
The Dutch Landrace is a traditional Dutch list of goat breeds, breed of domestic goat. It has been known in the Netherlands since the seventeenth century, and was formerly numerous there. It came close to extinction in the 1950s, but was saved by cross-breeding with unrelated goats, and by 2020 numbered over 2000 head. History The Dutch Landrace has been known in the Netherlands since the seventeenth century, and was common until the early twentieth century, when Swiss Saanen (goat), Saanen and Toggenburg (goat), Toggenburg goats were imported in large numbers and cross-bred with local stock. By 1958 only one pair of the goats remained, and attempts to find others were unsuccessful. Because the descendants of these two goats were heavily inbred, the decision was taken to cross-breed them with a number of unrelated goats. Numbers grew, and by 2020 there were some 2000 nannies and 200 billies. A breed association, the Landelijke Fokkersclub Nederlandse Landgeiten, was formed in ...

Cross-bred
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 ' ...

Goat Breeds
The goat or domestic goat (''Capra hircus'') is a domesticated species of goat-antelope typically kept as livestock. It was domesticated from the wild goat (''C. aegagrus'') of Southwest Asia and Eastern Europe. The goat is a member of the animal family Bovidae and the tribe Caprini, meaning it is closely related to the sheep. There are over 300 distinct breeds of goat.Hirst, K. Kris"The History of the Domestication of Goats".''About.com''. Accessed August 18, 2008. It is one of the oldest domesticated species of animal, according to archaeological evidence that its earliest domestication occurred in Iran at 10,000 calibrated calendar years ago. Goats have been used for milk, meat, fur, and skins across much of the world. Milk from goats is often turned into goat cheese. Female goats are referred to as ''does'' or ''nannies'', intact males are called ''bucks'' or ''billies'', and juvenile goats of both sexes are called ''kids''. Castrated males are called ''wethers''. While ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scimitar
A scimitar ( or ) is a single-edged sword with a convex curved blade associated with Middle Eastern, South Asian, or North African cultures. A European term, ''scimitar'' does not refer to one specific sword type, but an assortment of different Eastern curved swords inspired by types introduced to the Middle East by Central Asian ghilmans. These swords include the Persian shamshir (the origin of the word scimitar), the Arab saif, the Indian talwar, the North African nimcha, and the Turkish kilij. All such swords are originally derived from earlier curved swords developed in Turkic Central Asia (Turkestan). Etymology The English term ''scimitar'' is attested from the mid-16th century and derives from either the Middle French ''cimeterre'' (15th century) or from the Italian ''scimitarra''. The ultimate source of these terms is corruptions of the Persian ''shamshir.'' ''Scimitar'' became used to describe all curved oriental blades, in contrast to the straight and double edged ...

Lyre
The lyre () is a stringed musical instrument that is classified by Hornbostel–Sachs as a member of the lute-family of instruments. In organology, a lyre is considered a yoke lute, since it is a lute in which the strings are attached to a yoke that lies in the same plane as the sound table, and consists of two arms and a crossbar. The lyre has its origins in ancient history. Lyres were used in several ancient cultures surrounding the Mediterranean Sea. The earliest known examples of the lyre have been recovered at archeological sites that date to c. 2700 BCE in Mesopotamia. The oldest lyres from the Fertile Crescent are known as the eastern lyres and are distinguished from other ancient lyres by their flat base. They have been found at archaeological sites in Egypt, Syria, Anatolia, and the Levant. The round lyre or the Western lyre also originated in Syria and Anatolia, but was not as widely used and eventually died out in the east c. 1750 BCE. The round lyre, called so fo ...

Swiss Markings
{{Unreferenced, date=June 2019, bot=noref (GreenC bot) Goats expressing the Swiss Marked pattern have a black (eumelanin pigment) body and belly and tan (phaeomelanin pigment) legs, ears, and facial stripes. The allele which codes for this pattern is located at the agouti locus of the goat genome. There are multiple modifier genes which control how much tan pigment is actually expressed and so the tan areas can range from pure white to deep red. There may also be present dilution genes which turn the black areas in the pattern to either chocolate or medium brown. Image:Toggenburger.jpg, A Toggenburg goat with Swiss Markings.

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] |
Inbred
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 ...

Toggenburg (goat)
The Toggenburger or Toggenburg is a Swiss breed of dairy goat. Its name derives from that of the Toggenburg region of the Canton of St. Gallen, where it is thought to have originated. It is among the most productive breeds of dairy goat and is distributed world-wide, in about fifty countries in all five inhabited continents. History The Toggenburger is the traditional goat breed of the Toggenburg and Werdenberg regions of the Canton of St. Gallen in eastern Switzerland. The herd-book was started in 1890. At first, the goats were often dark-coated, sometimes with white markings; there may have been some cross-breeding with Appenzell and Chamois-coloured stock in neighbouring areas. The typical mouse-grey colour with white facial markings was fixed by selective breeding in the twentieth century. In 2006 there were 850 goats in the Toggenburg and the Werdenberg regions, out of a total of in Switzerland; this is much lower than in the 1950s, when there were more than . T ...

Saanen (goat)
The Saanen is a Swiss breed of domestic goat. It takes its name from the Saanental in the Bernese Oberland, in the southern part of the Canton of Bern, in western Switzerland. It is a highly productive dairy goat and is distributed in more than eighty countries worldwide. History The Saanen originates in the historic region of Saanen (french: ) and in the neighbouring Simmental, both in the Bernese Oberland, in the southern part of the Canton of Bern, in western Switzerland. It is reported from more than eighty countries. The total world population is reported to be over 900,000 head. Of these, some 14,000 are in Switzerland. It has since the nineteenth century been exported to many countries of the world, and has given rise to many local sub-breeds, often through cross-breeding with local goats. Among these local variants are the Banat White in Romania, the British Saanen, the French Saanen, the Israeli Saanen, the Russian White, the in Germany, and the Yugoslav Saanen. A ...
