Lipid was supplied to feedlot cattle diets in the form of corn oil for 90 d in efforts to alter muscle fatty acid composition. Forty-one heifers (Angus, Brangus, and Hereford) were fed one of two diets: 1) control, or 2) 4.7% corn oil. Research has proven the cis-9, trans-11 conjugated linoleic acid (CLA) isomer to be an effective anticarcinogen. Anabolic growth implants are widely used in beef production but have been shown to have varying effects upon carcass characteristics and muscle quality. Breed type had a greater effect upon carcass characteristics than lipid supplementation. Fatty acid concentrations of beef muscle were altered with lipid supplementation. Anabolic implants improved carcass weights while not adversely effecting overall meat and muscle quality. Meat tenderness was greater affected by muscle type than anabolic implanting.
