Animal welfare is a major concern in modern production systems, and recently, a framework for their inclusion in breeding objectives was proposed (Olesen et al. 2000). Despite evidence that animal behaviour is genetically controlled and can be modified by selection (Malmkvist and Hansen 2001) the possibility of improving animal welfare by selection is not generally considered an option. For example, Nimon and Broom (1999) concluded that no positive effects of selection in mink could be expected on temperament and adaptation.
