Crude fiber in forages in the form of Neutral Detergent Fiber (NDF) and Acid Detergent Fiber (ADF) is a constituent of plant cell walls. Non-Protein Nitrogen (NPN) are non-protein compounds that contain nitrogen such as amides, amines, amino acids. NPN is used by rumen microbes for the process of microbial protein synthesis. The aim of this study was to study the in situ digestibility of elepha…
