Low glucosinolate rapeseed meal (RM) was separated on sieves of 150, 270 and 450 µm diameter into 3 fractions defined as flour, bran and hulls. The fractions and rapeseed 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 ME (AMEN) of RM, fractionated material and model RMs was evaluated in two balance experiments conducted on 154 broiler chicken, 4 weeks old. After removal of bran and hulls, the protein content and AMEN 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 AMEN value of model RMs (P=0.01) according to the equation: AMEN (MJ/kg DM)=10.78-0.30 (% crude fibre)+0.20 (% crude fat).
