The Sustainable Southwest Beef Project is comparing conventional beef breed cattle to crossbred cattle of a conventional beef breed (Angus & Brangus) x heritage breed (Raramuri Criollo) to determine if a hardy, desert-adapted cow could be grazed on the rugged and arid rangelands often found in the Southwest, and, if bred to a conventional beef breed bull, still produce a calf that fits current American market expectations. This age progression video follows the first year of the study's calves through their maturation.
