Abstract: Several studies in swine feed composition have demonstrated that protein levels may be modified without significant changes in meat quality in terms of carcass, lean and back fat yield. However, this variation may change certain technical indicators, such as daily weight gain. The aim of this study was to calculate the carbon footprint of the finishing stage in swine production considering four scenarios of feed composition (P18, P16, P15 and P13). The life cycle assessment methodology was applied with a life cycle inventory based on reports in the literature. The feed composition used in P18 (no soybean hulls or maize starch) had the best environmental performance for global warming per kilogram of feed. However, when evaluating the life cycle of finishing swine, P16 (containing soybean hulls, maize starch and synthetic amino acids) exhibited better environmental results; the feed used in this scenario had better technical indicators (in terms of daily weight gain), thereby reducing the feed amount for finishing swine. Using the feed composition for swine P16, the impact may be reduced by an average of 12 % compared with P13 (a high level of soybean hulls, maize starch and synthetic amino acids).
