Long term success in the beef business depends largely on the continued support of beef consumers.  The world demand for quality beef is high, and the American Simmental Association (ASA) is committed to providing consumers with safe, affordable, and tasty beef.

ASA's Carcass Merit Program, Feed Conversion data and Calving Ease research establishes Simmental as a beef industry leader combining growth and carcass value with outstanding cow traits. ASA's research is backed by the most extensively documented and databased genetics in the industry

In addition to high value purebred cattle, Simmental genetics' flexibility allows operations to capture genetics from unique British and Continental sources in order to produce specialized animals for cattle exhibitors and other niche markets in the beef industry.
