Rumination, play and aggressive behavior as well as the bulls' access to shower were affected by heat stress. The effect of fan and sprinkler cooling on the second and third quarter of the year was tested between a group of six (6) Murrah buffalo bulls subjected to fan and sprinkler cooling and a group of six (6) Murrah buffalo bulls without fan and sprinkler cooling in a 6-month period. Duration in minutes of the behaviors were measured on the second day of the second week of the month. The average THI, which includes the average ambient temperature and average relative humidity for each month of observation that were used as a reference in this study were the same data that Bahia et al. (2019) recorded in their study. There were effects of months for all the behaviors. Dramatic changes were seen during the month of May when the highest degree of extreme severe heat stress was recorded. Bulls' duration of aggressive behavior was recorded longest during the month of May where THI level was also at a highest point. Play behavior (33.40±3.56 vs 15.06±2.89) was significantly higher in the experimental group than in the control group. Fan and sprinkler cooling had a positive effect on rumination time and play behavior of the bulls as it reduced the physiologic and metabolic effects brought about by heat stress. Duration of access to shower of the bulls follow a pattern similar to the recorded average relative humidity but opposing to the recorded THI level.
