The zebu cattle "breeds" of eastern and southern Africa are broadly classified into "large" and "small" types. Boran, Karamajong and Sudanese Zebu are examples of the former, while those of the latter include Angoni, Nkedi and Nandi. The habitat of the large zebu is drier than that of the small t...
