Abstract
Modern pig farming requires effective interdisciplinary decision-making tools to ensure profitability. A decision tool for pig growers based on a mixed integer linear programming (MILP) model to optimize the transportation strategy selecting the most profitable slaughterhouse is introduced. A sensitivity analysis is performed considering different pig growth and the payment grids serving to select the most suitable slaughterhouse.The base case scenario outperformed the official statistics on profits reported to the sector by 12.49 ct €/kg liveweight. Our findings also confirm the utility of selecting the most suitable slaughterhouse with potential enhancement of the economic outcome. Results confirm the current trend in slaughter heavier pigs of about 120 kg leading to a larger fattening period. Practical outcomes indicates that low growth pigs generated losses (-0.42 ct €/kg) while medium growth pigs (4.24 ct €/kg)
outperformed higher growth pigs (1.29 ct €/kg), suggesting that medium growth pigs are more efficient. The resulting model can be run quickly providing useful insights to decision makers managinf pig fattening farms.
