Fast-growth genotype steers placed on a high energy ration a month after weaning were
compared to a slow-growth genotype on a growing ration for 155 days, followed by a finishing ration
for 62 days. The fast-growth genotype produced heavier, higher quality carcasses in less time than
the slow-growth genotype, with similar energy conversion. Using contemporary prices. the fast-growth
genotype cattle broke even, and the slow-growth genotype lost $124 per head.
