Donkeys have been a source of draught power in many parts of the world from time immemorial. Three donkeys of different body weights were tested at six draught levels (16–34% of body weight) for 3 hours duration under sustained working to assess their draught capacity by measurement of physiological parameters and physical responses. A fatigue scorecard was developed to make optimum use of the donkey. This fatigue scorecard was analysed using dimensional analysis approach to develop a fatigue number as a function of draught, duration of work, speed and mass of donkey to assess the draughtability and fatigue of donkey under sustained working.
