At the Swedish University of Agricultural Sciences there are two professors of Ethology – Harry Blokhuis and Lena Lidfors . At SLU ethology is primarily 'applied' which means that studies are mainly focused at animals kept by man (agricultural animals, companion animals, horses and zoo animals). However, there are also basic questions addressed in our research. In our research we are always aware of the biological function of behaviour in the natural environment where it developed.
