Zebus (Bos taurus indicus) are the sacred cattle of India. Zebus have a characteristic hump over the shoulder and a large dewlap. They may be colored pale fawn, bay, gray or black. They interbreed with other kinds of cattle. Sometimes known as 'humped cattle', they are better-adapted to tropical environments than other domestic cattle. They have more sweat glands than European cattle (Bos taurus). They handle hot, humid climates well and have pest resistances not seen in European cattle.

There are 30 or more breeds, each of which originated in a province of India. Four main strains have been introduced into the United States.
