. En-premier-lieu, les lois générales des effets de la défaunation ont été établies à partir de l'analyse statistique d'une base de données de la littérature (méta-analyse) Dans un second temps, l'étude de quatre rations à base de fourrage (Digitaria decumbens) contenant 50

P. Uf, La production de viande a été déterminée par mesures de gain de croît moyen quotidien (GMQ) d' agneaux faunés et défaunés, en fonction des huit profils alimentaires (8 rapports PDIN /UF) Des mesures de flux duodénaux d'azote sur des béliers adultes fistulés, faunés et défaunés, nous ont permis d'estimer la protéosynthèse, Dans une seconde étude, quatre autres rations composées de fourrage avec complément La cellulolyse microbienne a été estimé par les mesures de dégradabilité in sacco des fibres (NDF), de digestibilité ruminale des fibres (NDF) ainsi que par la mesure des activités enzymatiques glycolytiques du rumen, sur ces mêmes béliers
