title: [The germinal population at embryonic stage and young age in the female hybrid duck born of male Pekin x female Barbary crossing. Comparison with ducks of the parent species].
abstract: As hatching the number of left ovary germinal cells of the female hybrid (Anas platyrhynchos x Cairina moschata) is weaker than that of the Peking and Barbary females because the small size of the genital crest limites the number of colonising germinal cells. As well after 16 days of incubation the multiplication of the oogonies stops in a way that we can not explain. The later growth of the ovarian follicle is, however, very fast, and the first laying is earlier than with the female parents.
