Resumen
Feed production and utilization are significant contributors to agricultural economic performance. Upon the market entry of new feedstuffs, livestock farmers are challenged to determine their price worthiness. In addition, transparent price formation is hampered under the conditions of new and often imperfect markets, thereby negatively impacting trade and impeding the development of sustainable markets. Therefore, this study proposes a decision support system that enables the effective valuation of novel feeds, such as white lupin (Lupinus albus L.). The proposed system is based on a linear optimization model that, by parameterizing the pricing assumption of novel feeds, determines their substitution value relative to conventional feeds. Notably, the substitution value of white lupin as a feed was found to vary significantly by animal species, production process, performance level, and cultivation year. However, with substitution values up to ?557 t-1, the value of white lupin was frequently far higher than the rarely available market prices (?270 t-1, as of 12/2021), suggesting that white lupin is a novel feed that is grossly undervalued due to imperfect market conditions. Overall, the proposed system can be used for objective pricing in these cases.
