The oxygen consumption ( V o 2 ) of three castrated male red deer was measured while they walked on a treadmill at 7° and 14° slopes and on the level at speeds varying from 44·3 to 172·9 m.min ‐1 . The energy cost of horizontal locomotion in excess of standing was 2·6 J kg ‐1 .m ‐1 . The cost of maintenance of posture when walking was the same as that of standing. The energy cost of walking up gradients was 21·5 J kg ‐1 .vertical m ‐1 . These results are discussed in relation to values reported for other species.
