The Simbrah breed emerged in the 1960's when breeders crossed Simmental and Brahman cattle. Although the breed originated in the Gulf Coast, an area known for its hot and humid climates, rigid selective breeding schemes have ensured that the breed has adapted to colder regions of the United States.
Simbrah cattle have inherited desirable traits from each of the foundation breeds. The influence of Brahman bloodlines sees Simbrah cattle enjoy heat tolerance, insect resistance, great foraging abilities, longevity and calving ease. Simmental bloodlines ensure early maturity, amply milk supply, fast growth, high fertility, and carcase quality. Simbrah cattle are often used in cross-breeding programs when superior maternal traits are needed to enhance a herd. Simbrah are also known for their ability to reach quality carcasses by 12 to 15months.
Simbrah are medium-sized cattle, whose coat colour varies between a number of colours. However red or black with white markings is commonplace.
The Australian Simmental Breeders Association Simbrah Register holds the herd book for Australian Simbrahs. The register has three categories: High Simbrah (75% Simmental, 25% Brahman), Medium Simbrah (50% Simmental, 50% Brahman) and Low Simbrah (25% Simmental, 50% Brahman). This flexibility has huge advantage in the market, as breeders can easily adapt herds to different environmental, management and market conditions.
