Sammanfattning
Dry matter (DM) yields, concentrations of metabolisable energy (ME), and crude protein (CP) of forages are all important on a dairy farm. This study examined DM yield and concentrations of ME and CP of forage mixtures of early or late maturing cultivars. Three mixtures were used in a randomised block design at Rådde, Länghem, Sweden, for three years. The field trial results were used to calculate silage production costs and diet costs at 38 kg ECM day–1. Mixtures of late maturing cultivars of timothy, red clover and white clover harvested three times resulted in similar yields of DM, ME and CP and concentrations of ME and CP as a forage mixture of earlier maturing cultivars of timothy, meadow fescue, perennial ryegrass, red clover and white clover harvested four times. When comparing number of cuts, four cuts resulted in higher concentrations of ME (+0.35 MJ (kg DM)–1) and CP (+20 g (kg DM)–1) and larger CP yields (+150 kg ha–1) compared to three cuts (P
