Abstract
The objective of the present work was to provide information on the histology and morphometry of the upper beak of developmental ages of Muscovy Ducks (Cairina moschata) by using forty-ninehealthy post-hatch Muscovy ducks of both sexes ranging from 1-60 days-old. The upper beak was a wide spoon-shaped in all examined birds. Its length measured 19.32 mm at one day old and increased to reach 65.52 mm at 60 days old. The upper beak rostrally formed a smooth circumscribed plate like a finger nail, therefore called the nail of the upper beak, the nail of the upper beak projected rostroventrally beyond the nail of the lower beak.Scanning by electron microscopy revealed that the free tip of the upper beak contained two transversely curved rows of smalldome shaped dermal papillae at one-day-oldstage. Later, 12-14 transversely curved rows of small papillae were observed behind the dermal papillae at 15 days old, which increased to 18-20 in numbers at 60 days old.In all examined age groups, the lateral edges of the upper beak have lamellae; the ventral parts of the rostrally situated lamellae directed caudally, but the caudally situated lamellae directed vertically. The dermis of the upper beak was formed of dense connective tissue containing numerous lamellated sensory corpuscles on both sides of the lateral edges of the upper beak
