Torun Wallgren


I am a PhD student at the Department of Animal Environment and Health, Divison of Environment, Care and Herd Health in Skara. I work with research, especially about pigs' behavior.


My doctoral project is called "Effect of the housing environment and management on the incidence of tail biting in pigs".

The project is part of the EU project FareWellDock, which has the overall aim to stimulate a non docking policy within the EU. The Swedish part of the project is primarily concernig how straw can be used as enrichment and prevent tail biting.

In my research, I primarily investigate the connection between straw use and the occurrence of tail biting / tail damage, with a focus on straw management in commercial herds.


I am a agronomist in animal science, and also hold a BSc and MSc in Animal Science from SLU.
