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