In this communication we descuss mathematical models that can be used to describe ammoniaN concentration profiles in the rumen of animals postfeeding. The unimodal pattern of ammoniaN profile following a single meal is modelled and analysed. Animals fed twice daily show bimodal patterns
where each component is separated due to the time interval between feeding times. Thus the selected model can be fitted to each peak separately. Various modelling options are explained and illustrated. There are three categories of models discussed: (1) summarising models to generate data for treatment comparisons, (2) kineticsbased models that furnish parameter estimates and meaningful functions thereof which can be used for treatment comparisons and (3) empirical models to generate quantitative information for further analysis. More complete information was obtained while analysing ammoniaN
profiles using kineticsbased models such as the critical exponential and summarising models such as the single Gaussian.
