Human visual observations of the pig's behavioural locomotion were performed offline on videos using 2-min instantaneous scan-sampling in four 30-min sessions on 6 selected days. Preliminary observations allowed for the selection of two morning sessions (session 1:09:30– 10:00 h and session 2:11:00–11:30 h)and two afternoon sessions (session 3:16:00–16:30 h and session 4:17:30– 18:00 h),to compare automated with manually labelled behavioural locomotion.
