Beefmaker cattle were developed by the Wright family beginning in 1972 on the NSW properties Wallamumbi and Jeogla. The breeding is based on a specially designed genetic program which involves infusing Simmental blood with specially-selected base Herefords.
The Beefmaker program was designed to produce an animal with faster growth rates, heavier carcass weights, an improved ratio of lean carcass meat to fat, maximum fertility, improved lactation, and greater stress tolerance compared to the two contributing base breeds.
After eight generations the Beefmaker has been stabilized at 75 percent Hereford and 25 percent Simmental content. It has established a national reputation for high conversion efficiency levels, high carcass yields, and low-maintenance costs.
