Poor milkers; long and sometimes loose horns that are shorter than those of Barotse; hump varies both in size and shape; coat colour is beige to brown in plain or patchy pattern.
Found in northern Angola and south-west DR Congo with nomadic pastoralists.
The Porto-Amboim, named after a coastal Angolan town of similar name, is considered to be a strain of the Barotse cattle in neighbouring Zambia, which descended from the Sanga cattle introduced into southern Africa when the Khoikhoi (Hottentots) first crossed the Zambezi river about 700 AD with their Sanga cattle. The Porto-Amboim must have developed with the expansion of the Barotse breed after the rinderpest epidemic (Felius, 1995). No breed improvement program exists.
