In the Pearson Square Method, where is the total crude protein value placed?

• A. In the center of the square
• B. On the left side
• C. On the bottom
• D. In the top corner

Answer: (A)

The target crude protein percentage for the final mix goes in the center of the Pearson Square. You place the protein percentages of the two ingredients on the left side (top and bottom), then subtract diagonally to find how many parts of each ingredient to use, which are written on the right. Putting the desired protein value in the center is what guides the whole balancing so the final blend hits the target.
