1
Phytic acid was analyzed for the positive control diet and the two basal diets. All the remaining diets were made from either of the two basal (negative control) diets.
2
Dietary electrolyte balance calculated as. Calculated from analyzed dietary sodium, potassium, and chloride concentrations (DEB, mEq/kg of diet = Na+ + K+ - Cl−, mEq/kg of diet); calculated values.
