Abbreviations: T_db = dry-bulb temperature, RH = relative humidity, T_dp = dew-point temperature, T_bg = black globe temperature, THI = temperature-humidity index, BGHI = black globe-humidity index, DMI = dry matter intake, MY = milk yield; ¹ Calculated from Lawrence [43]: T_dp = T_db − [((100 − RH)/5)((T_db + 273.15)/300)²] − 0.00135(RH − 84)² + 0.35; ² Calculated from Schüller et al. [44]: THI = (1.8T_db + 32) − [(0.55 − 0.0055RH)(1.8T_db − 26)]; ³ Calculated from Buffington et al. [45]: BGHI = T_bg + 0.36T_dp + 41.5.
