The formulation method is a link between nutrient input and nutrient waste. The commercial industry uses linear programming with databases in which the nutrients are adjusted with a margin of safety. Stochastic programming, a new method of formulating rations, is being explored as an alternative to linear programming with a margin of safety for feed formulation. Results have shown that stochastic programming more accurately meets requested nutrient probabilities. The result is a reduction in nutrient waste.
