Eighteen Holstein cows were evaluated in this research. The following frequencies were evaluated at 10-min intervals: stall occupancy, corridor occupancy, feeding, moving and being milked. The free-stalls were covered with rubber mattresses. Thermal variables such as dry bulb temperature, humid bulb temperature, black globe temperature and air velocity were recorded hourly. The data collections were made for 13 days in May, during autumn. Dynamics of social hierarchy was observed for 18 animals. The animals preferred to occupy the stalls located in quadrant 1, between the north and east axis, where there was less movement of people, tractors and vehicles. The cows occupied the free-stalls during the early morning and feeding occupancy was higher during the morning. Higher temperatures in the afternoon caused the longer occupation of the corridors by the cows during this period. Some dairy cows housed in a free-stall barn expressed dominant and/or hierarchical behaviors.  adairy cows  aOccupation rate  aRubber mattress1 aCAMPOS, A. T.1 aYANAGI JUNIOR, T.1 aPIRES, M. de F.
