Biochemical Changes During Draft Loading in Donkeys

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 1^st to 5^th days and 20 per cent draft load from 6^th to 10^th 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.
