Summary

The paper reviews information on the White Fulani cattle under the headings: origin, classification, distribution, population statistics, ecological settings, utility, husbandry practices, physical characteristics, special genetic characteristics, adaptive attributes and performance characteristics. It was concluded that the breed is economically important for several local communities in many West and Central African countries. The population of the breed is substantial. However, introgression from exotic cattle breeds as well as interbreeding with local breeds represent the major threat to the breed. The review identified a lack of programmes to develop the breed as being inimical to its long-term existence.

Resume

L'article repasse l'information sur la race White Fulani du point de vue: origine, classement, distribution, statistique de population, contexte écologique, utilité, pratiques de conduites, caractéristiques physiques, caractéristiques génétiques spéciales, adaptabilité, et performances. On conclu que la race est importante du point de vue économique pour diverses communautés rurales dans la plupart des régions orientales et centrale de l'Afrique. Le nombre total de cette race est important; cependant, l'introduction de races exotiques, ainsi que le croisement avec des races locales représente le risque le plus important pour cette race. Cet article souligne également le fait que le manque de programmes de développement à long terme représente un risque important pour la conservation de cette race.
