Two hundred and ten (210) laying hens of Black Harco breed at 37 weeks in lay were fed experimental layer diets, in which fermented palm kernel meal (PKM) and copra meal (CM) were used independently to substitute for soybean meal (SBM) on protein content basis at 0%, 25%, 50% and 75%, to give seven treatments in a completely randomized design feeding trial that lasted 12 weeks. Performance characteristics and some haematological indices were evaluated in this study. Fermentation for seven days increased the crude protein of PKM (from 20.04% to 23.42%) and that of CM (from 19.63% to 23.11%). The crude fibre of the fermented PKM and CM decreased (from 15.47% to 12.44 % and 16.00% to 11.63% respectively). The feed intake (FI) was significantly highest (P
