We employed multi-objective optimization to find the optimal mixture ratio of feed ingredients that minimizes the environmental and monetary costs of animal feed production while meeting the feed quality requirements. We employed the weighted sum method to deal with the multi-objective Nominal values and maximum allowed variation are reported in Table of the Supplemental Information. A maximum 𝜌𝜌 value was applied to restrict the ratio of each optimization class in our study, thereby ensuring the diversity of ingredients in the feed.
