aNDF Neutral detergent fibre (assayed with thermal-stable amylase and expressed inclusive of residual ash), ADFI Average daily feed intake, CATTD Coefficient of apparent total tract digestibility, DE Digestible energy, DMI Dry matter intake, NE Net energy
^aCalculated digestible energy, MJ/kg = (analysed dietary gross energy value, MJ/kg) × gross energy digestibility coefficient
^bCalculated using analysed dietary DE values
^cCalculated using calculated dietary NE values
^dCalculated as: lactation efficiency = total litter weight gain from d 0 to 26 of lactation (kg) × 1000/sow lactation energy intake (MJ/DE)
