Reducing dependency on imported protein sources for organic fattening pigs. Environmental life cycle assessment of feeding strategies based on green protein

Summary

An LCA cradle to farm gate approach was used to estimate the environmental impacts of five feeding strategies for organic fattening pigs. These included: S0 – Standard feed ratios with soybean cake and grass clover silage; S1 – Standard feed ratios with soybean cake and fresh grass clover; S2 – Green protein-based feed rations and grass clover silage; S3 – Green protein-based feed rations and fresh grass clover; and S4 – Low Green protein-based feed rations and fresh grass clover. Results were reported per kg live weight at farm gate for climate change (CC) including soil C changes; land occupation (LO); and biodiversity loss (BD).
