Caecal 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 کاملEpithelial 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 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...
متن کاملMalignant Melanoma in a Female Mallard Duck (Anas platyrhynchos)
Melanomas are malignant neoplasms originating from melanocytes. They reported in birds. In this case, macroscopic and microscopic (the histopathologic and IHC) findings supported a final diagnosis of cutaneous malignant melanoma in a mallard duck (Anas platyrhynchos). A female mallard duck (Anas platyrhynchos) was observed with a mass on the ventral portion of the neck. Th...
متن کاملCOMPARATIVE MICROANATOMICAL FEATURES OF THE RENAL CORTEX IN EMU (Dromaius novaehollandiae) AND DUCK (Anas platyrhynchos)
The present study was conducted on each of the three adult birds of Emu and Duck procured from the farms located in and around Gannavaram. The renal parenchyma of Emu and Duck was divided into large cortical lobules and smaller medullary lobules/cones. The renal cortex of both the birds showed a labyrinth of tubules and renal corpuscles. Small loopless cortical (reptilian type) nephrons and lar...
