| Sumario: | Africa is richly endowed with large numbers of indigenous livestock breeds. However, there is a
perception that a major constraint to livestock production is the limited genetic potential of these
breeds. This paper uses the Nguni from South Africa as an example, and demonstrates the role of
research in addressing such misconceptions. Initial studies on the Nguni in the early 1980s
indicated that the Nguni has the shortest calving interval of all beef breeds and its efficiency
exceeded that of most breeds. This resulted in a revived interest in the Nguni from the seed stock
industry, and the Nguni is currently numerically the sixth largest beef breed in the country. The
seed stock industry requires breeds to be competitive, hence a need for selection. This is in
contrast to keeping animals in their natural state, which implies a breed should remain the same
and be frozen in time. |
