Which combination makes up SimAngus HT (Heat Tolerance)?

• A. Simmental, Hereford, Brahman
• B. Simmental, Angus, Brahman
• C. Angus, Brahman, Charolais
• D. Simmental, Angus, Hereford

Answer: (B)

Heat tolerance in cattle comes from Bos indicus genetics, and SimAngus HT is made by blending that heat-adaptive component with strong performance traits. The combination of Simmental and Angus provides growth, carcass quality, and maternal ability, while Brahman brings the heat-tolerance adaptation that lets cattle perform well in hot environments. By including Brahman with Simmental and Angus, you get a three-breed cross that targets both productivity and tolerance to heat. Replacing Brahman with Hereford or Charolais would remove the heat-tolerance source, and leaving out Simmental would reduce growth and carcass traits, so the full trio best achieves the intended goal.
