Zebu n. : A bovine mammal (Ros Indicus) extensively domesticated in India, China, the East Indies, and East Africa. It usually has short horns, large pendulous ears, slender legs, a large dewlap, and a large, prominent hump over the shoulders; but these characters vary in different domestic breeds, which range in size from that of the common ox to that of a large mastiff.
