It is an international effort to breed a type of cattle that resembles the extinct aurochs, the wild ancestor of domestic cattle to a large extent. The project largely uses hardy cattle breeds with optic resemblance to the extinct aurochs. By crossbreeding and selective breeding it tries to establish similarity to the aurochs. The longterm goal is to release these Tauros cattle into rewilding areas. == Background == Megaherbivores are considered important tools of nature conservation in maintaining the biodiversity of open or park-like landscapes without human interference. Therefore, it is planned to reintroduce large game in several reserves to recreate the natural dynamics of the European ecosystems. The aurochs was one of the most important European ungulates, but was hunted to extinction over most of Europe in the Middle Ages. Despite attempts at conservation, the last known pure-bred auroch died in Jaktorów Forest, Poland in 1627. Thus, so-called rewilding has to work with its domesticated descendants, of which several breeds are hardy and robust enough to fill this gap. In many grazing projects, especially in Germany, Heck cattle is used, together with Galloways and Highland cattle. Heck cattle originated in the 1920s as an attempt by Lutz and Heinz Heck to breed an aurochs look-alike from several cattle breeds. Heck cattle turned out to be a hardy breed, but is found to be considerably different from the aurochs in several aspects. TaurOs Project formed to achieve a breed of cattle which is closer to the aurochs than previous breeding back attempts. This is based on the idea that original features of the aurochs are still present in some, less-derived cattle breeds and can be re-united by crossbreeding and selective breeding to the largest possible degree. Stichting Taurus has been running grazing projects with hardy cattle and horses for years and bought numerous cattle breeds found to be authentic for the project from southern Europe. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「TaurOs Project」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
