PC, nutrient sufficient diet; NC-1, 120 kcal/kg, reduce energy diet; NC-2, 3%, digestible amino acid reduced diet; 1X, 0.025% superzyme-CS addition; 2X, 0.05% superzyme-CS addition.
Overall, p-value for all treatment effect; Energy, p-value for enzyme effect on reduced energy diets; AA, p-value for enzyme effect on reduced amino acid diets.
PC, positive control; NC, negative control.
