Effects of finishing boars in mixed and single sex groups and split marketing on pig welfare

Introduction In Ireland, pigs were traditionally slaughtered at low weights and hence at a young age, which facilitated the rearing of boars. However, slaughter weights are increasing and this is associated with an increased risk of boar taint [1] and welfare problems [2]. Hence, changes in management and housing practices to facilitate rearing of heavy boars need to be investigated. The aims of this study were to investigate the welfare of pigs of both sexes in single or mixed sex groups and to evaluate effects of split marketing on pig welfare.
