Development of stomach of Muscovy duck (Cairina moschata)

The present study was implemented to provide comprehensive information on the developmental sequence of the proventriculus and ventriculus of Muscovy ducks by gross examination, macro-micrometric analysis and by using light microscope, scanning electron microscope (SEM) and transmission electron microscope (TEM). Samples from 55 healthy post-hatching Muscovy ducks of both sexes ranging from 1-60 days old.The difference between the examined age stages may be related to the feeding strategy (behavior) and the functional adaptations from the young to the older ages
