A finishing trial was conducted to evaluate the effects of corn oil on animal performance, carcass characteristics, and methane production in finishing cattle. Corn oil was supplemented at 3% of the diet (dry matterbasis) and led to a decrease in intake, a numerical improvement in average daily gain, and improved feed efficiency compared to the control cattle. Dry matter intake while in the methane barn was not decreased between treatments, although it was numerically similar to what was observed outside of the methane barn. Corn oil did not affect any carcass parameters. Methane production (g/d) was reduced with the inclusion of corn oil compared to the control. Methane (g/lb of gain) was also reduced with the inclusion of corn oil compared to the control. A numerical reduction of methane (g/lb of intake) was observed when corn oil was included in the diet. Corn oil appears to be a viable option for both improving performance as well as decreasing methane production in beef cattle finishing diets.
