abstract
The present study was undertaken to estimate the total protein and lipid in the Harderian gland of Pati ducks (Anas platyrhynchos domesticus) of Assam during the postnatal development. Total 45 (forty five) numbers of apparently healthy Pati ducks (Anas platyrhynchos domesticus) were utilized for present study. The quantity of total protein of the Harderian gland reflected a descending trend in advancement of the age of the birds. The quantity of the total lipids in the Harderian gland of Pati duck increased from 0 week age to 42 weeks age. The total lipid and total protein content of the Harderian gland of Pati duck were inversely proportional to each other.
