The effect of dietary particle size and enzyme supplementation on N and P excretion were investigated in a 3x2x2 factorial arrangement, with 3 particle sizes (400, 700, or 850 micro m), two levels of a carbohydrase cocktail (0 or 444 added units (U) beta -glucanase plus 1385 added U xylanase kg-1 diet), and 2 levels of phytase (0 or 374 added U phytase kg-1 diet), for a total of 12 dietary treatments.
