The PFT‟s were legume, spiny and aromatic for shrubs and sclerophyllous, deciduous and coniferous for trees. PFT‟s varied in crude protein (CP: 4.16- 15.87% DM) and in digestibility (IVOMD: 34.48-63.36%, p<0.001). Legume showed the highest CP and the IVOMD, coniferous showed the lowest CP content and aromatic showed the lowest value of IVOMD. In terms of the capacity of these PFT‟s to suppress the protein needs of livestock animals considering goats of 45 Kg body weight in dry periods (summer and autumn), the coniferous group alone can‟t cover the needs for maintenance. In the case of late pregnancy, only legume and deciduous and spiny can cover it.engGoatsLate pregnancyMaintenanceNorth of PortugalProtein needsconference paper
