This experiment describes the effects of two designs of individual cage-stalls on the behavioural and physiological responses of pregnant pigs. There was a total of 32 experimental pigs housed in two designs of cage-stalls, vertical or horizontal bars, and two control treatments, tether-stalls (vertical bars) and group housing. Video recordings taken of individually housed pigs (over 3 consecutive days) for 60 min day-1 (commencing 10 min after the start of feeding) after 14 and 49 days in treatments were used to determine the time pigs spent in three areas of the stalls (0-31, 32-63 and more than 63 cm from the front of the stall), number of movements between these areas, the duration that ..
