Abstract

Beef fatty acid profiles and superoxide dismutase activity were determined for cattle receiving OmniGen- AF supplementation (a patented nutritional supplement) at receiving (first 28 d at the feedlot) or throughout finishing (all 210 d of finishing) vs. a control group (non- supplemented). Th e most meaningful change in fatty acid composition from inclusion of OmniGen- AF was total poly- unsaturated fatty acid (PUFA) content where beef from the finishing group had more PUFA content in relation to the receiving group and was not different from the control group. Despite this increase in PUFA, cattle supplemented through finishing tended to have less lipid oxidation than the other two treatments yet this difference could not be explained by the superoxide dismutase activity.
