Value of High-Oil Corn Grain for Finishing Steers

Rolled high-oil corn in comparison with rolled isogenetic control corn was fed to finishing steers as 33%, 66% and 100% of the corn grain in their diet in a 134-day feeding trial. During the first 75 days of the trial, steers fed highoil corn had numerically lower rates of gain and tended to have poorer feed conversions compared with the control corn. At the end of the trial, there were not statistically significant differences in performance or carcass measurements of the steers fed the different amounts of high-oil or control corns. The results of this study indicated that the steers did not respond to the higher energy content of high-oil corn.
