Autor: Trail, J.C.M.

The limited genetic potential of indigenous cattle has often been quoted as a major constraint to beef and milk production in Africa south of the Sahara. Thus, considerable efforts have been and are being made to increase output through breeding programmes in many countries of the continent. Thes...
