The males ducks, reared for around twelve weeks, reach a live weight of between 4.2 kg and 4.9 kg, depending on their lineage.
In general, they are cut up for sale as fillets, thighs, manchon de canard, etc.
The females ducks, which are reared for around ten weeks, reach a weight of 2.4 kg to 2.7 kg, depending on their lineage.
The largest among them are sold cut, while the smaller ones are sold whole, ready to roast.
The result of cross-breeding a male Muscovy duck with a common female (generally a Pekin), these ducks are used to produce foie gras and magrets. For foie gras production, the males are more covetable than the females because:
- they are bigger than the females (a weight difference 300 to 600 grams per duck at the age of 12 weeks);
- their livers are of better quality than those of the females (which are often “veiny” and therefore unsuitable).
The Pekin is a domestic duck descended from the mallard.
These ducks grow quickly and produce good egg yields. The females are also crossed with male Muscovies to produce Mulards.
