Keep production assumptions separate from market assumptions
Agriculture calculations often combine physical production with cost and market assumptions. A yield estimate may be useful without predicting the market price. A feed or water estimate may organize daily needs without replacing animal specific guidance. Run a current case and a conservative case so you can see which assumption creates the largest change in the operating result.
- Yield, price, feed rate, capacity and operating cost are different inputs and should be tested independently.
- Use current field, livestock, equipment and product information when available.
- For regulated products or animal health decisions, follow labels and professional guidance.
