This study determines the relative effects of price, cattle quality, and feeding performance factors on profit per head for fed cattle marketed via a grid structure. Two different data sets of cattle that were marketed in two different grid pricing systems are used in the analysis with comparisons of results made between grids. Grid base price and feeder cattle price are the most important determinants of profit over time in both grids. However, considering only nonprice variables, the cumulative quality of cattle in a pen is also an important profit determinant.
