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

Abstract

This chapter focuses on the evaluation of different aspects within the NorFor system. This includes sensitivity analyses with respect to feed characteristics and model tests of total tract digestion, milk production, the energy system for growing cattle, RLI, feed intake and chewing index.
