Step 1 Draw Pearson’s Sqaure
Step 2 Label feeds and crude proteins percentages on the left corners and feeds on right corners. Make them Match
Step 3 Subtract the smaller number from the larger along the diagonal lines.
Step 4 Divide the parts of feeds by the total parts to find % of each feed in ration.  Parts of Feed  Total Parts
Step 5 Use total pounds needed to determine pounds of each feed needed. Amount of feed
Step 6 Check to make sure protein needs are met.
