As a consequence, consumptions of uncooked supplies for complete French compound feed manufacturing change drastically, through the use of rapeseed meals, over soybean meals (−425 000 t for CP-2) and sunflower meals, high-quality amino acids supplier and including extra grains, with maize replacing wheat. Raw material consumptions at regional scales are calculated from regional incorporation charges and regional feed tonnages. The incorporation charges of every uncooked material in feed are outlined by linear programming (simplex algorithm). It focuses on adoption charges in numerous regions based on penetration. The financial price, measured in euros (€) or in euros per tons of feed (€/t), is calculated within the model as a combination of incorporation rates and raw material prices. This mannequin evaluates the relative competitiveness of raw materials.
