Ducks: Mulard

Ducks: Mulard

General and economic characteristics

Mulards, sterile hybrids that derive from the interspecific cross between Barberia duck (Chairina moschata) and common duck (Anas platyrhynchos), are highly appreciated by gourmets as roast ducks and are also used for the production of fatty liver. This valuable product can also be obtained from the male Barbera and the Goose. Barbary males and common duck females are mainly used because of their better aptitude for spawning. From the reciprocal crossing, mulards are also obtained but with different results:
- male and female mulards of the same size (3.5-4.0 kg before ingestion) are obtained with the male Barberia x female common duck cross; animals of both sexes can be swallowed;
- with the male common duck x female Barbary crossbreed, females are much smaller than the males (2 kg compared to the 3.5 of the males always before being swallowed). Only males are swallowed.
The duration of the incubation period varies from 32 to 30 days depending on whether the duck is Barbera or common.

Duck liver

To obtain the mulards it is essential to favor the coupling between the two species because their behavior seems to be a limiting factor.
To remedy them, they raise females and males together to get them used to each other.
Despite the handicap of low productivity for ducklings, the production of mulard liver is increasing compared to that of the goose.
Among the advantages presented by the breeding and lingoing of the mulard compared to Alloca we mention:
- easy breeding thanks to rusticity and resistance to diseases;
- good resistance to lynching;
- shorter time of use for linging and performing the ingesting only twice a day;
- possibility of swallowing throughout the year;
- lower production cost;
- better quality and fineness of the liver.
Lindustria prefers doca livers because they are more voluminous (average weight 0.7 kg compared to 0.35 kg of mulard liver) and cheaper.
