Large Biological Type Medium Small Economic Scenario Standard cost/price relationships 500 300 - 25 Doubled Feedlot Feed Cost 105 100 -190 a. Graph profit versus economic scenario for the different biological types b. How should breeding objectives for these operations change as long- term economic scenarios change? c. Do genotype by economics interactions exist? If yes, describe them. d. If you are currently producing large feeder calves and you anticipated feed cost going even higher than doubled cost, what should be your breeding objective 3. Do the data in problems 1 and 2 suggest an intermediate optimum? Explain.
