How is the Pearson Square method used in formulating a ration?

The Pearson square or box method of balancing rations is a simple procedure that has been used for many years. It is of greatest value when only two ingredients are to be mixed. In taking a close look at the square, several numbers are in and around the square.Click to see full answer. In respect to this, how does Pearson square method calculate feed formulation? To use Pearson’s Square: Subtract the nutrient requirement (middle of square) from the nutrient concentration (on left of square) in the feed across the diagonal (top left – middle = bottom right; bottom left – middle = top right). Repeat this for both feeds.Subsequently, question is, what is the limitation of using the Pearson Square method? Use of a specific feedstuff may not allow formulation of the ration at 14% CP. You may be able to formulate to 14.2% CP using this feedstuff at a cheaper price than at using another feedstuff to formulate to 14% CP. Exceeding requirements but at a lower ration price (least cost). Likewise, people ask, what is the Pearson Square calculation and how does it work? The ‘Pearson Square’ is a tool that can be used to calculate the portion of two feeds needed to meet protein or energy requirements of an animal. For this tool to work, one of the feeds used must be higher in ME or CP than the desired level and the other feed must be below the desired level.What is ration formulation?RATION FORMULATION. Successful rationing involves achieving the best possible balance between a number of key nutritional, practical and financial factors. The most important priorities in rationing are: To deliver an adequate supply of the nutrients required to meet the cows’ needs.
