Estimating fractional rate of NDF degradation from in vivo digestibility
Fractional rate of degradation (kd) of potential degradable NDF (dNDF) was estimated based on in situ degradation profiles. In situ values were compared to values for kd which were calculated based on in vivo NDF digestibility and dNDF concentration for 61 forage samples including both young and very mature grasses and legumes. The calculation only failed for three samples, and in situ estimates correlated reasonably well to calculated values. Calculated kd for dNDF has a large potential for use in practice as a low resource method.
