Most cattle in this region are produced through the
3 phases of cow–calf, stocker, and finishing where cattle
are maintained on ranches through the first 2 phases and
then transported to feedyards for finishing. To obtain the
impacts of a representative production system of this type,
simulated values were obtained for 9 cow–calf ranches, 3
stocker ranches, and 3 feedyards simulated across the region.
Mean values for the 3 types of operations are listed
in Table 5 with all results expressed per unit of CW. This
CW includes that of cull cows and bulls from cow–calf
operations and finished steers and heifers.
