A note on the energy cost of walking in cattle

SUMMARY Measurements were made of the heat production of cattle while standing at rest or walking on a treadmill at different speeds, both on the level and at a gradient of 6°. The energy cost of horizontal locomotion was about 2 J/kg per m at speeds of 40 to 85 m/min, irrespective of body weight or plane of nutrition. The energy cost of vertical locomotion was about 26 J/kg per vertical m.
