There were four treatments arranged factorially, with two sources of fibre (WB or MC) and two concentrations of ES (0 or 0.15g/kg) that contained 800U/kg of endo-1,4-[beta]-cellulase, 1800U/kg of endo-1,3(4)-[beta]-d-glucanase and 2600U/kg of endo-1,4-[beta]-xylanase. The digestibility of the neutral detergent fibre was higher (P Author Affiliation: Universidade Tecnica de Lisboa, Instituto Superior de Agronomia, Tapada da Ajuda, 1349-017 Lisboa, Portugal Article History: Received 28 November 2006; Revised 5 December 2007; Accepted 7 December 2007
