a Requirements are listed as percentages or as units or mg/kg of diet.

b These are typical ME concentrations for corn-soya diets. Different ME values may be appropriate if other ingredients predominate.

c These concentrations of vitamin D are satisfactory when the dietary concentrations of calcium and available phosphorus conform with those in this table.
