¹DM Dry matter; ²uCP Utilisable crude protein; ³RNB Ruminal nitrogen balance; ⁴aNDFom = Neutral detergent fibre after treatment with amylase and cinefaction;
⁵degradable XS + XZ = degradable starch + sugar; ⁶NEL Net energy for lactation, Phase 1⁷ = Date of drying off to two weeks ante partum, Phase 2⁸ = Two weeks ante partum until partus
