Methane emissions (CH4) from ruminants depend on the dry matter intake (DMI) and quality of the diet. The aim of this study was to obtain local emission factors of CH4 from grazing steers in two seasons of contrasting pasture quality and during the finishing period. Average CH4 (g/d) produced during summer grazing was 39% higher than the finishing period (P
