1 SEM = standar error of mean. 2 aNDFom = NDF assayed with a heat-stable amylase and expressed exclusive of residual ash, 3 ADFom = ADF expressed exclusive of residual ash. 4 NSC = non-structural carbohydrate = (100 − (CP + Ether extract + Ash + aNDFom)). 5 NEL = net energy lactation. A,B,C: p ≤ 0.01, a,b,c: p ≤ 0.05.
