Stochastic Feed Formulation
The purpose of commercial feed formulation is to balance nutrients in diets to meet the nutritional requirements of animals at least cost. Almost all commercial feed formulation software use Linear Programming for feed formulation. In real life nutrient composition is highly variable. This variation is associated with variety of factors which include variation of nutrient content of ingredients coming from different batches and sources and variation attributed to the laboratory procedure and human error. For example if a same sample of soybean is analyzed multiple times for protein content, it is very likely that every time a slightly different value will be obtained. Same sample analyses in different laboratories or by different persons usually results in highly variable values. In Linear Programming method a mean value of these analytical values is used for formulation. Statistically, these mean values are associated with only 50% confidence of meeting the requirements in prepared formula.
