In Nutrient Dynamics, knowledge of digestion and metabolism of nutrients in farm and companion animals will be extended and quantified. Students will read and discuss scientific papers on five various topics, such as microbial metabolism, growth in ruminants and nutrient based feed evaluation systems. Quantitative understanding of these topics will be obtained by application of extant mathematical models and developing new models. These models are mechanistic, i.e., based on understanding of the underlying processes involved. The behavior of the whole system under study is analyzed in terms of its components and their interactions with one another. The simulation results will be presented in short reports and will be discussed.

Learning outcomes:

After this course, the students are able to:
- provide a critical assessment of problems and possibilities into the partitioning of nutrients in farm and companion animals, in particular with respect to its quantitative aspects;
- recognize and evaluate developments in feed evaluation studies;
- raise scientific questions, evaluate adequacy of methodology and interpret results from scientific papers on animal nutrition;
- develop and apply mechanistic models of digestion and metabolism in farm and companion animals;
- prepare and present research findings from scientific literature and own simulation results orally and in written abstracts.


- to read scientific papers and to discuss the development and data interpretation of experiments on selected topics in tutorials;
- to utilise extant mechanistic models of digestion and metabolism in farm and companion animals and interpret simulation results;
- to develop mechanistic models based on hypotheses and data from literature;
- to report and discuss simulation results.


- written exam (50%);
- participation to discussion (20%);
- reporting simulation results and subsequent discussion (30%).
For every part of the examination, a minimal grade of 5.0 is required.


- study guide;
- simulation language manual;
- lecture materials, including scientific papers on selected topics.
