Zebu are very common in much of Asia, including China, Pakistan, India, Nepal, Bangladesh and almost all countries in Southeast Asia. In Asia, taurine cattle are only found in the northern regions such as Japan, Korea, and Mongolia, possibly domesticated separately from the other taurine cattle originating from Europe and Africa). Other species of cattle domesticated in parts of Asia include yak, gaur, banteng, and water buffalo.
