Although Bali (native breed of Indonesia) cattle has already adapted to tropical conditions, but this breed was reported to be in heat stressed under the high ambient temperature. This study was conducted to evaluate the effect water sprinkler on the physiological responses of Bali cattle during the hot season. Two groups of 6 young Bali males were used in this study. The animals were kept individually in an animal house and fed with rice straw and native grasses supplemented with rice bran and urea multinutrients molasses block. The first group (control group) was kept without water sprinkler and the second group (treatment group) was treated with an individual water sprinkler located about 1 m above the animal. The water sprinklers were applied for 6 consecutive days, three times a day (8.00, 12.00 and 16.00 hr.) each lasting for 30 minutes. The physiological responses (body temperature, respiration rate and pulse rate) and ambient temperature were measured at 05.00, 09.00, 13.00, 17.00, 21.00 and 01.00 hr. Daily water intake was recorded. Mean ambient temperature at 05.00, 09.00, 13.00, 17.00, 21.00 and 01.00 hr. were 20.50º, 32.17º, 37.33º, 30.00º, 21.67º, and 20.33ºC, respectively. Treatment group showed a significant (P
