1 Diet C: concentrate (oats, soybean meal) and late harvested grass haylage (35:65 energy ratio), Diet G: early and late harvested grass haylage (80:20) (+small amount soybean meal), Diet L: lucerne haylage and late harvested grass haylage (80:20). 2 The estimated energy values, in mega joule, of the forages were calculated from the in vitro digestible organic matter values [22]. 3 Hemicellulose and cellulose concentrations in the feeds were calculated by weight difference: NDF-ADF and ADF-ADL, respectively. 4 Non-structural carbohydrate and non-starch polysaccharide concentrations in the feeds were calculated NSC = 100 − (NDF + protein + fat + ash) and NSP = NSC − (starch + sugars), respectively [5]. 5 Free glucose, free fructose, sucrose, fructans and maltodextrins. a,b,c Mean values within a row with unlike superscript letters were significantly different (p < 0.05).
