Although a relatively young science, farm animal ethology has a considerable contribution to make to the development of housing systems. Two areas are highlighted in this review. First, the evaluation of existing housing systems is exemplified by studies of the effects of close confinement on sows. From such studies it has been concluded that close confinement can cause distress in sows. Secondly, the development of new housing systems is exemplified by studies on how pen design can control aggression.
