Ruminal Dry Matter, Neutral Detergent Fibre and Acid Detergent Fiber Degradation Kinetics of Dominant Pasture Forages in Kurdestan Province of Iran

Neutral detergent fiber (NDF) is a major chemical component of forages and its degradability (dNDF) is an essential parameter in predicting their energetic value. Moreover, dNDF has been used in models to estimate the physical fill of fibrous feeds in the rumen and, therefore, the intake capacity of animals. As the available information on the nutritive value of pastoral forages is limited a study was undertaken to measure chemical composition and cell wall degradation kinetics of eight pasture forages in the rumen
