Extract

Unlike most of Spain, Galicia's temperate, humid climate supports year-round grass growth, with a moderate summer drought. Local lamb markets demand lean, light carcases (10-12kg) produced from lambs grazing whilst still with the ewe. Grazing systems studies with the native Gallego breed, Flores (1992) established optimum grazing heights as 8.0 cm for individual lamb liveweight gain (LWG) and 5.5 cm for LWG/hectare but no data were recorded on the carcase yield. The objective of this trial was to test whether optimum individual LWG and carcase yield is obtained under these systems.
