How to Calculate a Simple Feed Mix Using Pearson's Square

Step 1: Choose a grain from the column on the left side of this screen. Enter the grain name in the box for the grain's name and the and grain percent in the box for the grain's percent. For roasted soybeans the entry will be Roasted Soybean as the grain's name and 37 as the grain's percent.

Step 2: Enter the target protein. A common number here may be 16.

Step 3: Choose a protein concentrate or another grain from the column on the left side of this screen, or choose something not listed. Enter the concentrate name in the box the and concentrate percent in the box for the concentrates's percent. For soybeans the entry will be soybean as the concentrate's name and 37 as the concentrates's percent.

Step 4: Press the calculate button.

Using the results: For the above example a ratio of 3 parts corn to 1 part soybean is calculated. Using this calculation, for every 30 pounds of corn 10 pounds of soybean should be added. To make a 400 pound batch, 300 pounds corn is mixed with 100 pounds soybean.
