Least Cost Recipe
A standard practice in the livestock feed industry is to formulate diets on a “least cost formulation”. In short the formulator for the feed manufacturer establishes a set of minimum nutrient standards for the diet (or recipe) and they may even set minimum and/or maximum allowable amounts of various feed ingredient restrictions. The various ingredients are priced to establish a value and then a computer program least cost formulates the diet. This means the lowest cost that meets the minimum specifications of the diet using the available ingredients. This may be fine for feedlot cattle and hogs on a finishing diet but many companies utilize the same strategy for your family pet foods. This is especially true of grocery store and big box store offerings which are merely focused on price. Do you want your family pet subject to ever changing formulas and the “cheapest” diet a manufacturer can produce?
