The effect of environment and work conditions on oxygen consumption, methane and carbon dioxide emission from he-buffalo have been studied under a controlled environment using animal treadmill. The environment temperature of the he buffalo was varied in two temperatures (17 and 37°C) inside environment controlled chamber. In each temperature he-buffalo was made to exercise with two speeds (1.5 and 2.5 km/h), two treadmill inclinations (0 and 5° with the horizontal) and three draughts (no load, 10 and 12% of bodyweight) for three effective hours. The oxygen consumption of the he-buffalo was observed to be increasing with the increase in temperature, speed, inclination of treadmill and duration of exercise. The typical minimum percent increase in oxygen consumption during the study was found to be 11.09% at 17°C temperature and 45% humidity, 0° inclination of treadmill, speed of 1.5 km/h and no load condition whereas the maximum percent increase was recorded as 639.86% at 37°C temperature and 45% humidity, 5° inclination of treadmill, speed of 2.5 km/h and 12% draught. The methane concentration in exiled of he-buffalo also showed an increasing trend with the increase in temperature, speed, inclination, draught and duration of exercise. The typical minimum increase in percentage of methane concentration was found to be 9.66% at 17°C temperature and 45% humidity, 1.5 km/h speed, and 5° inclination of treadmill, no load condition. The maximum percent increase of methane concentration was 67.51% in and 17°C temperature and 45% humidity, 2.5 km/h speed, 5° inclination of treadmill, 12% draught. Carbon dioxide concentration in the exiled gas decreased with the increase in temperature, speed, draught and duration of exercise. The maximum percent change in carbon dioxide concentration was found to be 5.48% at 17°C temperature and 45% humidity, 2.5 km/h speed, 5° inclination of treadmill, 12% draught and minimum percent change in carbon dioxide concentration was found to be 0.77%, at 17°C temperature and 45% humidity, 1.5 km/h speed, 5° inclination of treadmill, no load condition.
