Abstract
The present study was conducted to evaluate the different production and reproduction performances of khaki Campbell ducks reared under intensive and extensive systems of rearing. Signicantly (P≤0.05) higher body weight was observed in ducks reared under intensive system of rearing. Signicant differences (P≤0.05) were also found in age of laying and egg production but the difference in egg weight was non signicant between the two groups. The mortality was found to be 5% under intensive rearing system and 9% in extensive rearing system. No signicant differences were observed in average egg length and width between the two groups. This study revealed that the overall performance of khaki Campbell ducks are better under intensive system of rearing than extensive system of management but economically extensive system of duck rearing is more benecial than intensive system in Assam.
