In the region of Sayago (Zamora, NW Spain), traditional management practices based upon systematic grazing Agrostietalia order communities are declining. As a result, some areas are being overgrazed, whereas others are underused. This work tries to prove that systematic grazing management (5-6 times during the herbage growth period) acts as a regulating factor of forage resources and allows good quality forage to be obtained [crude protein (CP) equal to 150-200 g per kg DM; crude fibre (CF) equal to 210-260 g per kg DM; organic matter digestibility (OMd) equal to 64-61 per cent] without large production losses (22 per cent of DM). Moreover, herbage growth rates (41-105 kg per ha per day) of other pasture communities allow reserving areas to be harvested or grazed when feed availability falls
