Effects of Lipoic Acid Supplementation on Finishing Steer Growth Performance, Carcass Merit, Beef Tenderness, and Beef Retail Display Properties

Effects of Lipoic Acid Supplementation on Finishing Steer Growth Performance, Carcass Merit, Beef Tenderness, and Beef Retail Display Properties

Angus cross steers (n = 84; BW =325 ± 3 kg) were used to evaluate the effects of lipoic acid (LA) supplementation on growth performance, carcass merit, beef tenderness, and beef retail display properties. Treatments were control (no LA), 8mg of LA/kg of BW per d (LA8), and 16mg of LA/kg of BW per d...

Zusammenfassung:Angus cross steers (n = 84; BW =325 ± 3 kg) were used to evaluate the effects of lipoic acid (LA) supplementation on growth performance, carcass merit, beef tenderness, and beef retail display properties. Treatments were control (no LA), 8mg of LA/kg of BW per d (LA8), and 16mg of LA/kg of BW per d (LA16). Lipoic acid was incorporated into an extruded corn flour pellet and top-dressed onto a finishing diet for 125 d. Steers were subsequently delivered to a commercial abattoir for harvest. Carcass data and left-side longissimus sections (6th to 12th rib) were collected from each carcass at 24h post-mortem. Steaks from each longissimus section were analyzed for Warner-Bratzler shear force (WBSF) and color. Final BW of control steers was greater (P
