Excerpt from the report Summary: To determine the value of dehydrated alfalfa meal (dehy) in poultry feeds, intrinsic value curves were developed using the parametric linear programming technique. The points on the curves corresponded to points of substitution—points at which a nutritional factor in dehy substituted for a nutritional factor from some other source. Configuration of the curves was dependent on the quality of dehy, the specifications of the ration being formulated, competitive ingredients, and ingredient prices. Changes in any of these factors usually resulted in significant alterations in curve configurations. At each solution point (point of substitution) on the curve, a complete ration formula was obtained, shadow prices were established for ingredients not entering the solutions, and opportunity costs were specified for ration requirements.
