Pelleting is the most prevalent heat treatment in the production of poultry feed. Metabolisable energy values of mash and steam pelleted complete maize-type broiler finisher diet was investigated in an experiment with 24 individually followed Ross hybrid male chickens. Altogether four balance periods were compared. Heat treatment significantly (P < 0.001) increased classical metabolisable energy and nitrogen-corrected metabolisable energy values by 3.00 % and 2.99 %, respectively.
