Barley and maize were combined with lupin seeds or maize gluten meal so that the 4 blends present different rumen degradation rates for their carbohydrate and/or nitrogen constituents. The measured values (dm) of DM degradability in sacco of these concentrates were higher before and lower after 8 h of incubation compared with the calculated values of degradability (dc) obtained by the additive method according to their composition. The differences (dm - dc) were the highest for the less degradable feeds
