We did (and continue to do) substantial research on cattle breeds. Black Angus is predominate in the commodity-driven prime beef Missouri production. While this breed was originally a British/Scottish breed, it's "Americanization" has produced a large-frame cattle with various traits that mostly have to do with fattening quickly on a corn-based diet after they are weaned. This commodity approach with its feedlot base is unfortunately responsible for most of the bad press that beef has gotten in the last quarter-century.
