Environmental improvement of pig production: construction and assessment of eight models of pig farms for the future
Résumé
In a context where husbandries are questioned on their environmental impacts, optimized systems for the future should be devised to pro-vide the milestones. Eight pig systems were constructed by experts by considering the use of best available techniques (BAT), the mod-ernization of buildings and the improvement of technical performances. The kilogram of pig produced from each optimized system was assessed at farm gate using Life Cycle Assessment (LCA) and the results were compared to an average current pig system in conventional production. The results indicate a reduction of impacts which could reach respectively 39, 43, 26, 26 and 45% for climate change, acidifi-cation, eutrophication, land occupation and energy use. The implementation of BATs is limited by their cost. Husbandries should improve their technical performances more than those of the 10% best current husbandries to maintain the current cost of production.
