DIETARY SUPPLEMENTATION OF VITAMIN-E TO FEEDLOT CATTLE AFFECTS BEEF RETAIL DISPLAY PROPERTIES

Beef products from carcasses (n = 20) of cattle fed supplemental vitamin E and beef products from commodity carcasses (n = 20), used as controls, were compared to determine effects of increased vitamin E tissue levels on display appearance of fresh beef held in supermarket and simulated retail conditions. Meat from cattle fed supplemental vitamin E contained higher levels of alpha-tocopherol (P < 0.05) and, over time, exhibited less lipid oxidation, brighter lean color and lower discoloration. Monitoring supermarkets for discounted retail meats showed increased levels of alpha-tocopherol in beef extended caselife and decreased the incidence of discounted beef products.
