ABSTRACT Oxygen consumption, respiratory frequency, and the of expiratory interclavicular air sac gases were continuously monitored in six female domestic fowl trained to exercise on a treadmill for 10 min periods at normal or elevated temperatures. At temperatures (20 ± 2 °C) cost locomotion rose from 0·46 ml O2 kg-1 m-1 0−3 km h-1 0·77 maximum speed 4·3 h-1. 32 2°C, increased by as much 20% compared Hyperventilation occurred all speeds both End-tidal parallel manner with speed, latter remaining consistently 6−7 Torr less than former rest during exercise.
