This method, a straightforward tool used in animal nutrition, helps formulate rations to meet specific nutrient requirements. It employs a simple visual square to balance two ingredients to achieve a desired nutrient concentration. For instance, if a target protein percentage is needed for cattle feed, and two feed sources with varying protein levels are available, this tool helps calculate the proportions required of each. It visually represents the differences between the nutrient content of the ingredients and the target value, guiding the user to determine the correct ratio.
This nutritional balancing technique provides a practical, accessible method for feed formulation, particularly in situations where access to complex software or calculators is limited. Its simplicity makes it a valuable tool for small-scale farmers and livestock producers. Developed by Henry Pearson in the early 20th century, this method has remained a relevant and cost-effective solution for basic ration formulation, contributing significantly to efficient livestock feeding practices worldwide.
