text: Contrary to the Northern rangelands where NAPCO operates is the Southern rangeland industry. Angus and Hereford cow breeds are the customary species of cattle utilised in these rangelands. However, since the 1980s European breeds such as the Charolis and Limousine were introduced The introduction of these European breeds comes from their high growth rates and ability to sustain a heavy weight despite their age as the cows grow older. Like the Northern rangeland industry, the South has also introduced crossbreeding to develop composite breeds. Hereford cattle species are typically the traditional species the industry relies upon, due to the breed's climate suitability, heat tolerance and strong tick resistance. The Hereford species is well suited to both grain finishing and grasses as its primary form of sustenance, and for that reason is also able to produce high quality and dense carcasses. In the 1990s the Wagyu breed was introduced in the Southern rangelands and grew in popularity the next few years due to the marbling of their meat and pattern of maturation which is comparatively later to that of the other species that was being used in the Southern rangeland. Although the number of Wagyu cattle is low in comparison to other breeds in South Australia, crossbreeding programs between Wagyu bulls and Angus cows have been used to accelerate the dissemination of Wagyu genes.
