Cairina moschata
The mulard (or moulard) is a hybrid between two different genera of domestic duck: the domestic Muscovy duck ("Cairina moschata domestica") and the domestic duck ("Anas platyrhynchos domesticus"). American Pekins are most commonly used to breed mulards due to the breed's high meat production. Like many interspecific F1 hybrids, mulards are sterile, giving them the nickname "mule ducks". While it is possible to produce mulards naturally, artificial insemination is used more often with greater success.
