A patented proprietary product, OmniGen- AF, was evaluated to extend beef steak shelf- life at 8, 22 and 29 days of aging. Th e three treatment groups included a control group with no supplementation, OmniGen- AF supplementation for28 d aft er receiving, and supplementation for 210 d during finishing. Th e inclusion of OmniGen- AF had no effect on tenderness or visual discoloration under retail display conditions and minimal effects on fatty acid composition. Although color stability seemed to be unaffected by the supplementation, feeding OmniGen- AF throughout the entire feeding period tended to decrease oxidation. Supplementing cattle with a greater concentration of OmniGen- AF or increasing the antioxidant components in the feed supplement could be explored to further maximize beef shelf- life following long periods of aging.
