Swiss Guidance for severity assessment

This document provides information for the Swiss cantonal authorities responsible for animal experiments, their advisory committees and all persons concerned with animal experiments. 

It is intended to serve as a guideline for careful assessment of the severity of animal experiments and the genetic constraints on the animals, in order to allow correct classification of animal experiments in severity categories. It is also intended to promote efforts to implement the 3R principles in the longer term. 

The guidance can be downloaded as a pdf file here.
