Digestion and metabolism in the gastrointestinal tract

  • Chapter
NorFor - The Nordic feed evaluation system

Part of the book series: EAAP – European Federation of Animal Science ((EAAP,volume 30))

Abstract

In NorFor the digestion and metabolism are simulated in three compartments: (1) the rumen, (2) the small intestine and (3) the large intestine. This chapter describes the modelling of the digestion processes in the three compartments and the microbial OM synthesis in the rumen and large intestine. Most of the equations in this chapter could have been presented in a simpler form, but we present them here in the format they are implemented in the computer program since we believe this makes it easier to follow their biological rationale.
