Abstract
Crossbreeding effect on sexual dimorphism of body weight in intergeneric hybrids obtained between Muscovy and Pekin duck
Highlights
The very large body weight sexual dimorphism in favour of males in the Muscovy duck is well known [9, 10!. It seemed to be small in Pekin duck as in the progeny of the mating of Muscovy drake with Pekin duck female which gives the mule duck, and to be as in Muscovy in the reciprocal cross which gives the hinny duck (12)
That is consistent with the finding that Pekin duck have maximum growth rate earlier than Muscovy ducks
The body weight sexual dimorphism seems to depend on the Muscovy duck dam and not on the Pekin one
Summary
The very large body weight sexual dimorphism in favour of males in the Muscovy duck is well known [9, 10!. It seemed to be small in Pekin duck as in the progeny of the mating of Muscovy drake with Pekin duck female which gives the mule duck, and to be as in Muscovy in the reciprocal cross which gives the hinny duck (12). Gomot and Bonin [5] studied the male hybrid between Pekin drake and Muscovy female duck. They concluded that it presents on the whole a predominance of the maternal characteristics
