The Australian Milking Zebu (AMZ) is a composite breed of dairy cattle, developed by the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Australia during the mid-1950s. To develop the breed, the CSIRO bred Sahiwal and Red Sindhi cattle from Pakistan with Jersey cattle. Some Illawarra, Guernsey and Friesian genetics were also included.[1] The development of the breed was governed by strict selection for heat tolerance, milk production and cattle tick (Boophilus microplus) resistance to result in the modern AMZ breed.

The zebu (/หziหb(j)uห, หzeษชbuห/; Bos indicus), also known as indicine cattle and humped cattle, is a species or subspecies of domestic cattle originating in South Asia.[4] Zebu, like many Sanga cattle breeds, differ from taurine cattle in the fatty hump on their shoulders, their large dewlap, and their sometimes-drooping ears. They are well adapted to high temperatures and are raised throughout the tropics.
