The appraisal of thermo-adaptability among two calf breeds in the controlled environment was the objective of this study. The first group was Tharparkar and second one was crossbred (Hariana; 25 and 50% and Exotic; 50 and 75%) calves. The investigative period consists of 7 days acclimatization period, and 21 days of thermal exposure at control (25°C), moderate (31°C) and severe (37°C) heat stress (6 hrs. per day). There had 9-10 days recovery period across each exposure. During the investigation period, the blood was collected on 1st, 6th, 11th, 16th, 21st day. The DMI of both breeds decreased in 31°Cand 37°C of heat exposure and increase in water intake was relatively more in Crossbred than Tharparkar calves. Also, non-significant variation (P.0.05) in relative expression of IL-1β and IL10 among Crossbred and Tharparkar calves was recorded.
