Considering different environmental footprints in feed optimization is crucial for comprehensively evaluating the environmental impact of the produced feed. Our analysis revealed that the choice of environmental indicator, e.g., the impact of land stress on biodiversity or climate change, results in the selection of different feed ingredients from distinct countries of origin (Fig. ). Specifically, the impacts of land stress on biodiversity are decisive for origin selection, particularly for barley and wheat for pig feed (Fig. ), and for soybean for broiler feed (Fig. ). While barley from Great Britain was primarily chosen for optimizing pig feed when considering land stress, barley from Ukraine was also selected as a viable option when considering climate change. The climate change impacts for barley are similar for both countries; however, the impacts of land stress on biodiversity are roughly seven times greater for barley from Ukraine than for that from Great Britain (Figs. ). For broiler feed, soybean was selected more often from Canada when optimizing for land stress impacts due to the roughly two times greater impacts of land stress on biodiversity for Ukrainian soybean.
