Sanga cattle is the collective name for indigenous cattle of sub-Saharan Africa. They are sometimes identified as a subspecies with the scientific name ''Bos taurus africanus''.〔(Relationships between production and product traits in subpopulations of Bonsmara and Nguni cattle ) P.E. Strydom1, R.T. Naudé, M.F. Smith, A. Kotzé, M.M. Scholtz and J.B. van Wyk, South African Journal of Animal Science 2001, 31(3)〕 These cattle originated in East Africa, probably the western shores of Lake Victoria, and have spread west and south. Sanga are an intermediate type, probably formed by hybridizing the indigenous humpless cattle with Zebu cattle.〔 〕 However, archaeological evidence indicates this cattle type was domesticated independently in Africa, and bloodlines of taurine and zebu cattle were introduced only within the last few hundreds years.〔Caroline Grigson: ''(An African origin for African cattle? — some archaeological evidence.'' African Archaeological Review 1991, Volume 9, Issue 1, pp 119-144 )〕 Although the timeline for their history is the subject of extensive debate, some authors date the first Sanga cattle to 1600 BC, while alternative evidence shows bones found in East Africa dating to 7000 years ago.〔References Payne, 1964 and Schoeman, 1989 in (Relationships between production and product traits in subpopulations of Bonsmara and Nguni cattle ) P.E. Strydom1, R.T. Naudé, M.F. Smith, A. Kotzé, M.M. Scholtz and J.B. van Wyk, South African Journal of Animal Science 2001, 31(3)〕 They are distinguished by having small cervicothoracic humps instead of the high thoracic humps which characterize the Zebu. ==Breeds of Sanga cattle== * Abigar * Afrikaner * Ankole-Watusi * Bonsmara (a breed developed in the 1940s in South Africa) * Nguni * Red Fulani * Tuli * Tswana 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「sanga cattle」の詳細全文を読む スポンサード リンク
