Epithelial Diversification of Thyroid Gland in Kuttanad Duck (Anas platyrhynchos domesticus) - A Postnatal Study
The study was conducted on 104 female Kuttanad ducks from day-old to 24 weeks of age and the birds were selected randomly from a single hatch for the study. The thyroid glands were collected from eight birds in each group at fortnightly intervals. After recording the gross features, the material was fixed using different fixatives and then processed for histological studies. The paired thyroid ...
متن کاملInterrenal-Chromaffin Tissue Ratio in the Adrenal Gland of Kuttanad Ducks (Anas Platyrhynchos Domesticus) During Post Hatch Development
The interrenalchromaffin tissue ratio (IC ratio) in the adrenal gland of Kuttanad ducks was studied during post hatch development in 78 female birds of 13 age groups from day-old to 24 weeks of age at fortnightly intervals. The measurement was read out from the pictures by the use of “ImageJ software”. The proportion of interrenal tissue in the whole gland was least at sixth week of age (1.15:1...
متن کاملCaecal Development in Kuttanad Duck (Anas Platyrhynchos Domesticus)
Caecum, the largest part of duck’s intestine has an important role in liquid absorption, cellulose digestion and defensive mechanism. Age related changes in the histomorphology of the caeca in Kuttanad ducks were studied in 72 birds from day-old to adult at fortnight intervals. After recording the biometry and gross features, the material was fixed in neutral buffered formalin and standard proc...
متن کاملHistochemical and Ultrastructural Studies on the thyroid gland of Pati Ducks (Anas platyrhynchos domesticus) of Assam
A total of 36 ducks were utilised in this study ranging in age from 2 weeks upto 40 weeks of age. For histochemical parameters, the thyroid glands were separated out of the thoracic cavity and the required representative tissue samples were preserved in deep freeze maintained at -80oC. For scanning electron microscopy the tissue samples were processed by SAIF, NEHU, Shillong. The colloid showed...
متن کاملDevelopmental ossification sequences of the appendicular and axial skeleton in Kuttanad duck embryos (Anas platyrhynchos domesticus)
The processes of ossification sequences are poorly investigated for birds in general, even for domestic and experimental species and when it comes to the waterfowl it is almost negligible. Such sequences constitute a rich source of data on character evolution, and may even provide phylogenetic information. A pre-hatch developmental study on ossification sequences of axial and appendicular skele...
