Data from a western Kansas feedlot were analyzed to estimate the quantitative impacts of price and performance variables on profits per head from finishing cattle. Sale prices, feeder prices, and corn prices had the most impact on profit variability over time. Differences in sale prices, feeder prices, and feed conversions were important in explaining the difference in steer and heifer profits over time. Results suggest that breakeven prices should be calculated for a range of fed cattle, feeder, and corn prices, and that these three variables need to be stochastic in representative farm modeling efforts.
