Patterns of stereotyped behaviour were observed in pregnant sows maintained in different housing systems in commercial farms. The stereotypies were compared between stalled and tethered Large White sows (124 and 68, respectively) and between stalled and group-housed Large White/Landrace crosses (81 and 71, respectively) on 2 farms in each case. The patterns of stereotype were observed for 1 h after food distribution. The proportion of sows developing stereotypies did not differ between stall-housed and tethered females (89.5 and 94.1%), but was lower in group-housed compared with stall-housed sows (66.2 vs. 92.6%). The stereotypies presented by tethered sows were predominantly licking and rubbing, whereas in stalls or group-housed, they were most frequently biting and vacuum oral activities.
