Effect of concentrate level and slaughter body weight on growth performances, carcass traits and meat quality of Barbarine lambs fed oat hay based diet

► Two concentrate levels (CL, 300 g and 600 g) were used for fattening Barbarine lambs. ► Two slaughter weights (SW) were prefixed (34 and 42 kg). ► High concentrate level increased carcass yields, compactness and adiposity. ► Later slaughtering increased carcass yield and fatness without modifying compactness. ► CL and SW influenced meat color and fatty acid composition.
