Abstract: Four experiments were conducted to assess the effects of processing conditions on nutritional value of expeller-extracted canola meal (ECM) and the replacement value of expeller and cold-pressed canola meals in broiler chicken diets. The first two experiments evaluated and characterized the effect of processing conditions such as conditioning temperature (90, 95 or 100 °C) and screw torque (high or low) during oil extraction process on apparent metabolizable energy (AME), apparent and standardised ileal digestibility of amino acids of ECM for broiler chickens. The values obtained in these two experiments were used to formulate diets with high inclusion of ECM to investigate the effect of a microbial multi-carbohydrase obtained by fermentation from 'Aspergillus aculeatus' (Ronozyme® VP), and a microbial mono-component protease (Ronozyme® ProAct), in diets on productive traits, nutrient digestibility and partitioning of energy in broiler chickens. The fourth experiment was designed to determine if reduced feed intake of birds fed CM-based diets, per se accounts for growth depression and if this retarded growth rate can be attenuated by increasing dietary digestible amino acid levels of the diet.
