Welcome to Genetics Australia NZ

Australia’s leading dairy breeding organisation Genetics Australia is giving New Zealand dairy farmers continued access to a large range of leading Australian dairy sires as well as a select group of genetics sourced from the northern hemisphere. 

Genetics Australia has been working for over 60 years to develop a grazing dairy cow that produces well from pasture but can also respond when challenged with additional feed and they have incorporated the best genetics from around the world in their breeding program following the Australian Breeding Values systems (ABVs). 

The end result is an infusion of the best international sires combined with leading Australian cow families to produce bulls which breed efficient, fertile, profitable milk producers, predominately from a grazing diet which combine to create a positive contribution to the national dairy herd in New Zealand. 

Genetics Australia NZ looks forward to assisting you to achieve your goals of ‘breeding better herds’.
