Abstract
The present investigation was undertaken for comparative study of blood biochemical constituents of Pati and Chara-Chemballi ducks in their laying period (42 weeks age). Twelve each of the ducks were procured from Barpeta district and SIRD of Assam and blood samples were collected from the wing veins from each bird under aseptic condition. The results showed that the serum glucose, ALT and ALP level was found to be significantly higher in Chara-Chemballi duck than Pati duck except serum calcium level which was significantly higher in Pati duck. The total protein of blood serum did not differ significantly in both the genetic groups of ducks.The variation between the two genetic groups might be due to difference in breeds, hormonal and other nutritional aspects. It is concluded that significant differences in blood biochemical profile among the two genetically different ducks could be considered as a references values and this may serve as a guide to assess the state of health in the monitored birds as well as it might be helping the physiologist, pathologist and poultry scientists for preparation of effective production strategy.
