Four compound feeds, with 0, 5, 10 and 15% partially pitted olive cake (90.9% dry matter, DM) replacing the same proportion of barley were given ad libitum to growing pigs, using chromium oxide as digestibility marker. Energy digestibility (dE) of diets showed a linear decrease (P=0.04) with olive pulp percentage (dE= 77.94 (± 0.77) – 0.2087 (± 0.083) x olive cake). By estimating dE and digestible energy content (DE) of barley from its chemical composition (80.30% and 3518 kcal/kg DM), the dE of olive cake resulted 59.43%, and its DE content 3195 kcal/kg DM. This value is much higher to that estimated from its chemical composition (2495 kcal/kg DM), and it is not far from that of barley, as it is shown by the scarce differences (P>0.10) between diets in DE content. The DE content of partially pitted olive cake when included up to 15% in diets for growing pigs was 9% lower to that of barley, and its inclusion within this range scarcely dilute energy concentration of diet
