Abstract

A two-year experiment evaluated the effects of sorting long yearling steers by initial feedlot BW and supplementing 200 mg/steer of Optaflexx daily the last 28 days of the feeding period on ADG, F/G, carcass characteristics and profitability. Feedlot ADG, F/G, and profitability were not effected by sorting. However, sorted cattle exhibited increased fat thickness, increased ribeye area, and increased percentage of carcasses with a yield grade of four or higher. Supplementing Optaflexx the last 28 days of the feeding period had no effect on feedlot performance, carcass characteristics, or profitability.
