The farm was visited in March, August, and November during 2001 to observe the behavior of gestation females. Three trained observers walked quietly along the rows of stalled females and observed three postural behaviors (standing, not standing, and sitting) and three stereotypies (drinker play, vacuum chewing, and bar biting) at 15-min intervals for 6 h by time sampling (Martin and Bateson, 1993) starting from the end of the morning feed distribution between 0730 and 0800. Relative frequencies of the postural behaviors and the stereotypies for 6 h were expressed as a percentage of a total of 25 time observations.
