The fractions and rape seed oil were mixed in different proportions in order to obtain 25 model rapeseed meals differing in crude fibre 8.8, 10.3, 11.8, 13.2 and 14.7% DM and in crude fat 4.3, 6.3, 8.2, 10.2 and 12.1% DM (two-factorial design). The digestibility of nutrients and apparent metabolisable energy (AME N ) of RM, fractionated material and model RMs was evaluated in two balance experiments conducted on 154 broiler chicken aged 4 weeks. After removal of bran and hulls, the protein content as well as AME N value of the remaining fraction increased by 16 and 10%, respectively, in comparison with RM. Crude fibre content negatively and crude fat content positively affected AME N value of model RMs (P≤0.01) according to the equation: AME N (MJ/kg DM) = 10.78 - 0.30 (% crude fibre) + 0.20 (% crude fat).
