Pearson’s Square is a simple, quick way to calculate the amounts of feed necessary to meet a nutrient requirement of livestock and other animals. This method is most effective when only two feeds are being used. For example, when two grains are mixed for part of a total mixed ration (TMR) or as a supplement to pasture feeding, Pearson’s Square can be used to determine what quantity of each grain would be needed to achieve a specific nutrient level in the mixture.
