The results illustrate the dynamics of endogenous N compounds in the different parts of the gastro-intestinal tract of sheep. Secretion and reabsorption are influenced by dietary factors such as fibre content. The major part of the secreted nitrogen compounds is reabsorbed in the small or large intestine. Thus, the amount of secreted N much exceeds the metabolic faecal nitrogen
