cows on each program each year. The kinds and amounts of feed fed varied from year to year, but basically the cows received corn silage, a protein supplement or a ration mixture, and a mineral mixture. However, in calculation cost of supplemental feeds and minerals for each program, the kinds of feed and amounts used was those comsumed by the cows in the 1971-72 season (Table 15).

Amount of Beef Produced The annual production of beef from calves, on each program (per acre and per cow) was calculated from the average calf crop weaned and the average weight of calves when they were removed from the pastures (Table 16). No credit was given for change in cow weights, but a figure was included in beef pro- duction for normal culling of cows. The percentage of cows nor- mally sold as culled cows in a commercial herd each year was estimated to be 12%. This figure was used to estimate the amount of beef sold from a culled cow on each program. The production of beef from a calf varied from 306 pounds per acre on Program 2 to 370 pounds on Program 3. Production of beef per acre from a culled cow was 93 pounds on Program 2 and 105 pounds in Program 3. The gross weight of a calf and a culled cow was reduced by 4% to adjust for normal shrinkage in marketing. The adjusted sales weight of beef produced from a calf was 294 pounds on Program 2 and 355 pounds on Program 3. Gross and adjusted production of beef from a calf and culled cow were not adjusted for supplemental feeds fed during the winter period, since costs of such feeds were included in the total costs calculated for each program.
