Abstract

Effect of a dietary antioxidant in dietswith or without wet distillers grains plus solubles (WDGS) was evaluated for performance and carcass characteristics. The 2 x 2 factorial design consisted of 1) an antioxidant at 0 or 150 ppm (Agrado Plus) and 2) WDGS at 0 or 30%, which replaced dry-rolled corn. Feeding the antioxidant did not affect performance (P > 0.31) or carcass characteristics (P > 0.25). Feeding WDGS increased (P < 0.01) final body weight (BW), dry matter intake (DMI), and average daily gain (ADG) while decreasing the feed to gain (F:G) ratio (P < 0.01). Carcass characteristics were affected (P < 0.01) by feeding WDGS, which increased HCW and fatness.
