An experiment combining Simmental with Brahman that began in the pastures of a few dedicated cattlemen in the late 1960s has evolved logically into the breed called Simbrah. The Brahman or Zebu, the most numerous cattle type on earth, contributes heat and insect tolerance, hardiness and excellent foraging ability, as well as maternal calving ease and longevity.
The Simmental complements these excellent traits with early sexual maturity, fertility, milking ability, rapid growth and good beef characteristics. The very docile disposition of most Simmental is also a plus for this composite. These two cattle breeds have been used in cooperation to produce Simbrah, superior in many ways to the parent breeds.
They are popular in warm climates as they possess both the heat resistance of the Brahman as well as the Simmental frame.
