PY - 1999/// TI - Evolution of the parameters (CP, TDOM) in natural communities in the Sayago Region (NW Spain) of feeding interest of the autochthonous bovine breed 'Sayaguesa' T2 - Dynamics and sustainability of Mediterranean pastoral systems PB - Zaragoza : CIHEAM VL - 39 T3 - Cahiers Options Méditerranéennes SP - 63-66 A2 - Etienne M. AB - The greatest part of the 'Sayaguesa' bovine breed specimens live within the Sayago Region (Zamora - Spain) and their feeding is based on the use of plant forage from meadows and mowing of the area. The evolution of crude protein (CP) and total digestible organic matter (TDOM) indicate that it is possible to modify the guidelines of usage of these surfaces with the aim of better use of their nutritive potentials.
