The aim of the experiment was to investigate the effects of a feed enzyme (pentosanase) and a dietary fat in diets with a high crude fibre content on growth and metabolism in pigs. The basal diet contained 50 % whole maize plants. The four treatments were as follows: C-control (without supplement), E-enzyme (200 ppm pentosanase), F-extracted fat (50 g/kg), EF-enzyme (200 ppm pentosanase), and extracted fat (50 g/kg). Feed intake, feed conversion ratio, and daily weight gain were not significantly influenced by either enzyme or fat addition. There was a tendency of lower total feed intake, FCR, and higher daily weight gain as an effect of pentosanase. Dietary fat as well as feed enzyme addition positively influenced the digestibility of energy and the degradability of NDF and ADF. The inclusion of both supplements to the diet did not have any additive effect on the digestibility of energy and the degradability of NDF and ADF. It seems that dietary fat supplementation inhibits the positive effect of pentosanase
