Effect of strain (Khaki Campbell, Indigenous) and age (224 and 280 days) of ducks on the physical egg quality and presence of off-flavour in eggs was studied. The average of egg weight, yolk index and percent yolk weight for the two ages under study were significantly (P0.05) higher in Indigenous duck eggs whereas the same average value for albumen index, Haugh Unit score and percent albumen were higher in Khaki Campbell eggs. However, shape index, yolk colour score, shell thickness and percent shell weight of eggs were comparable for the two strains. Age of ducks had an insignificant influence on shape index, albumen height, shell thickness and yolk index as evident from the least difference between average values of two strains under study. But, the average values of the two strains under study were significantly affected by age for A.I., H.U. score, % albumen weight, % shell weight and % yolk weight. Presence of off-flavour was more pronounced in Khaki Campbell eggs than that of indigenous eggs.
