Various research methods are used in biology, animal production and life sciences research (the focus areas at WUR). For example, computer models can be used to make calculations and forecasts. Laboratory experiments are suitable for modelling processes or investigating sub-processes in the human or animal body.
These methods are undergoing rapid developments and are leading to increasingly better results, but there are occasions when animal experiments are still needed. In some cases, an animal experiment may even be a legal requirement. Animal experiments are also used for educational purposes.
