Animal input characteristics,such as BW, is also needed when calculating ruminal variables, such as passage rates of feed fractions out of the rumen and efficiency of microbial protein synthesis. Moreover, the physical activity of the animal (simply classified according to whether it is loose or tied up) will affect the IC and energy requirements.

backdrop

Feed calculations in NorFor,alculated from information based on chemical fractions, and their degradation and digestion characteristics. Nevertheless, efficientuse of a feed evaluation system in practice requires commercial feed analyses that are reliable and can be performed at a low cost. Therefore, several feed characteristics are predicted using either . methods or NIRS.

Prediction of milk yield, weight gain and utilisation of N, P and K,t and production level. Keep track on excreted N, P and K are of interest when estimating plant fertilising value and also evaluating the impact of excreted N and P on eutrophication of the environment.

System evaluation,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.
