Abstract

Cattle fed a de-oiled dry distillers grains plus solubles (DDGS) diet (50% DM basis) were compared to cattle fed a corn- based control diet to determine effects on discoloration, oxidation, color, and tenderness of beef aged for 2, 8, 14 and 21 days. Dietary treatment had no effect on tenderness. From the fourth day of retail display, beef from animals fed de-oiled DDGS had greater lipid oxidation and greater percentages of discoloration. Th e de-oiled DDGS treatment also showed greater discoloration aft er 21 days of aging. While feeding de-oiled DDGS did not impact lipid oxidation at 2, 8 and 14 days of aging, at 21 days of aging, meat from cattle fed de-oiled DDGS had greater oxidation in comparison to a corn- based diet.
