Increasing NEXT ENHANCE (NEXT) essential oils in finishing diets containing Rumensin® and Tylan® were evaluated on performance and carcass characteristics. Treatments consisted of 0, 75, 150, 225, or 300 mg per steer daily of NEXT. Increasing NEXT linearly decreased DMI and F:G, but ADG was not different among treatments. Feed conversion (F:G) was improved by 4.0% and 3.8% when feeding NEXT at 225 and 300, respectively, compared to steers fed 0 NEXT. Therefore, results suggest that feeding NEXT at rates of 225 and 300 improves feed conversions in feedlot finishing diets containing Rumensin and Tylan.
