The incorporation of ethanol industry co-products, such as dried distillers grains plus solubles, to feedlot diets in the United States may be inadvertently exposing cattle to high amounts of dietary sulfur. High sulfur diets have repeatedly been reported to decrease growth and carcass performance, health, and copper status; however, little to no information is available concerning the implications that high sulfur diets have on the antioxidant capacity or meat quality of cattle. Thus, the subsequent research trials were designed to: 1) examine the impacts of high dietary S on diet digestibility and macro and micro mineral absorption and retention, 2) determine the effect of supplementing a rumen-protected vitamin C during the entire finishing period of steers on growth performance, trace mineral status, antioxidant capacity, carcass characteristics, and meat quality, 3) determine the optimal dose of supplemental vitamin C within a high sulfur diet on growth performance, blood metabolites, carcass characteristics, and meat quality, and 4) identify the influence of timing of vitamin C supplementation during the finishing period on growth performance, plasma vitamin C and glutathione concentrations, and carcass characteristics. Within our first research objective, the consumption of a high sulfur diet for at least 28 days decreased copper, manganese, and zinc retention in steers. These trace minerals are components of antioxidant enzymes, suggesting a lesser availability of these minerals may decrease antioxidant capacity of the animal. Within our second research objective, supplementing vitamin C (10 g per steer per day) to calf-fed steers consuming a high sulfur (0.55%) diet for 149 days prevented a decline in circulating ascorbate throughout the finishing period and increased marbling scores from high Select to low Choice compared to the high sulfur, non-vitamin C supplemented steers. The inclusion of vitamin C to the high sulfur diet prevented the ratio of oxidized-to-reduced
