Popis: In four change-over experiments, dairy cows were fed wilted grass silages (G1, G2, G3, G4 and G5) ad lib. In early lactation, silage was supplemented with 7 kg of concentrates and in late lactation with 1 kg. The silages were harvested at different growth stages, resulting in different cell wall contents (G1 44.6%, G2 54.7%, G3 54.8%, G4 64.1% and G5 with 67.3% neutral detergent fibre (NDF)). With an increase in cell wall content, crude protein (CP) content decreased (21.3% CP for G1 to 11.2% CP for G5), and organic matter (OM) digestibility decreased (P
