The Red Fulani cattle, which are called the Jafun in Nigeria and Cameroon, and Fellata in Chad, as well as other names such as the M'Bororo, Red Bororo, or Bodaadi, another subspecies is the "Sokoto Gudali" and the "Adamawa Gudali" or simply "Gudali", which means "horned and short legged" in the Hausa language. The widely accepted theory for the origin of present-day zebu cattle in West Africa is that they came from the westward spread of the early zebu populations in East Africa through the Sudan. Other breeds of zebu are found mainly in the drier regions. Their body conformation resembles the zebu cattle of eastern Africa. The zebu did not appear in West Africa until about 1800. The increasing aridity of the climate and the deterioration of the environment in the Sahel appear to have favoured the introduction and spread of the zebu, as they are superior to longhorn and shorthorn cattle in withstanding drought conditions.
