Formulate chicken diets using Pearson square

The Pearson square, also known as the balancing equation, is a tool used to formulate balanced chicken diets using two ingredients. Here is a step-by-step guide on how to use the Pearson square to formulate a chicken diet:

  1. Determine the nutrient levels of the two ingredients you want to use in the diet. You’ll need to know the crude protein, crude fat, and crude fiber content of each ingredient.
  2. Calculate the nutrient levels of the diet as a whole. To do this, you’ll need to determine the proportion of each ingredient in the diet. For example, if you want to use 50% ingredient A and 50% ingredient B, the nutrient levels of the diet will be the average of the nutrient levels of the two ingredients.
  3. Calculate the nutrient imbalance. Using the nutrient levels of the diet and the desired nutrient levels for your chickens, calculate the nutrient imbalance by subtracting the desired nutrient levels from the actual nutrient levels.
  4. Adjust the proportion of the ingredients. To correct the nutrient imbalance, you’ll need to adjust the proportion of the two ingredients in the diet. To do this, use the Pearson square to solve for the unknown proportion of one of the ingredients.
  5. Recalculate the nutrient levels of the diet. Once you’ve adjusted the proportion of the ingredients, recalculate the nutrient levels of the diet to ensure that it meets the desired nutrient levels for your chickens.
  6. Repeat the process as needed. If the nutrient levels of the diet are still not balanced, you may need to repeat the process of adjusting the proportion of the ingredients and recalculating the nutrient levels until the desired balance is achieved.

Using the Pearson square to formulate a chicken diet can help ensure that your chickens are receiving the proper nutrients for optimal growth and health.
