The present investigation was carried out to study the effects of draft load on biochemical parameters glucose, cholesterol, urea and lactate in donkeys. Six male donkeys 4 to 5 years of age were subjected to loading exercise (i.e. 10 per cent draft load for 1st to 5th days and 20 per cent draft load from 6th to 10th day). A highly significant (P<0.01) increase in serum lactate and urea and highly significant decrease in glucose level at 10 per cent and 20 per cent draft load was noted. Cholesterol showed non-significant (P<0.05) effect at 10 per cent and 20 per cent draft load.
