The purpose of the study is to observe the status of morning temperature and humidity of the dairy cows' living environment. The collected data were temperature and humidity measured with dry and wet bulb thermometers. These primary data were processed using THI equation which was specific for dairy cow and classified into six classes based on THI index: (1) comfort; (2) mild discomfort; (3) discomfort; (4) alert; (5) danger; and also (6) emergency.
