Augmenter l’autonomie protéique des élevages de porcs bretons : co-conception et évaluation de systèmes de culture intégrant des fourrages sources de protéines

Abstract : In order to increase the protein self-sufficiency of the conventional Breton pork farms and lower their dependency to soybean oilcakes the project FOURPROPORC is studying the consequences of the incorporation of fodders sources of protein in the pigs’ meals. Several species and presentations are tested : wrapped hay silage, silage or dehydrated alfalfa, wrapped hay silage of purple clover or of multispecies crop. Besides the zootechnics trials, this study aims to evaluate the consequences of the incorporation of these fodders on the durability of cropping systems adapted to their production. To achieve this, a typology of the Breton pork farms has first been realised. From the latter, new cropping systems have been co-created to fulfill the constraints of 12 scenarios of feeding, and have been evaluated ex ante thanks to a multicriteria evaluation on their economic, social and environmental dimensions, with the evaluation tool MASC. The results show that most of the new cropping systems have an equal or higher durability than the control ones. This first evaluation, simulated in the context of the experimentation platform, opens to other evaluations in other pedoclimatic contexts, for a better representativity. Once they are realised, they will enable, along with the zootechnic trials, to confort the choice of taking these new feeding systems on.
