Origin of Breed

The SimAngus Breed was created in the late 20th century in response for a demand for a crossbred animal combining the superior qualities of the Simmental with Angus or Red Angus. This cross has proven a very popular as a means of producing cattle with high performance and high market acceptance levels. The SimAngus breed combines the best traits of both parent breeds. Superior weight gain, muscling, meat yield and maternal traits of the Simmental with the meat quality, polled and solid coat color attributes of the Angus and Red Angus. Popularity of these breed mixes has created a strong demand for both bulls and females with varying combinations of Simmental and Angus/Red Angus. A registered SimAngus animal comprises between 1/8 to 7/8 Simmental and 1/8 to 7/8 Angus or Red Angus. Breeders of SimAngus can choose the percentage breed mix to suit their own herds and the markets they supply.

Physical Description

SimAngus are either solid black or red in color and are polled. They are moderate to large framed. Mature bulls weigh around 2,200 to 2,800 lb. while mature Simmental cows weigh from 1,100 to 1,500 lb.

Defining Characteristics

The SimAngus breed features females that are very maternal with high calving ease. These females exhibit excellent fertility and milking ability. Their calves are very growth and finish with an ideal fattening pattern. They are known for their excellent carcass quality, high meat yield and meat quality. With their longevity, they produce many calves during their lifespan. They are very docile and are easy to work with on any operations. SimAngus are able to finish well in the pasture or on the feedlot. Selected females representing the very highest value genetics both in their Simmental pedigrees and their Angus or Red Angus lineage have the potential to be the most valuable genetic packages available to the seedstock and beef industry. These cattle are truly seedstock and have the potential to be valuable A.I. stud bulls, donor cows or foundation females.

According to the USDA’s Meat Animal Research Center Report 22, SimAngus progeny ranked first in calving ease, weaning weight, percent choice, carcass weight, pounds post gain, feed efficiency by weight gain, percent puberty, maternal calving ease, and feed efficiency by marbling over all other continental breeds. In the same report, they also ranked first in calving ease, weaning weight, carcass weight, post wean gain, pounds of real product, shear force, feed efficiency by marbling and maternal weaning weight over all British breeds. The American Simmental is genetically engineered toward efficient, economical production of tender, lean, palatable beef -- the product in demand by consumers today.

Development in America

SimAngus cattle have become very popular all over the United States on many farms, ranches, feedlots and other operations. The American Simmental Association designed the SimAngus breed. The Association was founded in 1971 with the start of its first herd book. SimAngus is a federally trademarked title held by the American Simmental Association.
