"The samples of grass and grass silages were evaluated for organic matter (OM) degradability using two cannulated steers. The rumen incubation times were 0, 6, 12, 24, 48, 72 and 96 h. The disappearance rates of OM were used for calculation of immediately soluble fraction (a value), potentially degradable fraction (b value), fractional degradation rate of b (c value) and the effective degradability (ED value). The objective of the present study was to develop the prediction equations for these degradation characteristics from the chemical composition of observed forages. For grass forages the best predictors of parameter b (P<0.01) were crude fibre (CF) and acid-detergent lignin (ADL) and parameters a, c and ED were described (P<0.0001) by neutral-detergent fibre (NDF) content.
