Inter-specific and intra-specific hybridization in ducks for meat production

Date

2-1979

Abstract

The fertility, hatchability and meat production performance of two hundred and sixty six (266) ducklings from the inter se and cross matings of Mallard (Anas boschas), Pekin (A. platyrynchos) and Muscovy (Cairina moschata) and from inter se and cross matings of the American, Australian, Chinese and Pekino varieties of Pekin ducks were observed up to 14 weeks of age.

The percentage fertility and hatchability of the eggs from the inter se and cross matings of the three duck species differed. In general, the fertility of the eggs from the crosses was poorer than those from the inter se mated ones. Percentage hatchability did not show consistent differences between the inter se and the cross matings. On the other hand, the percentage fertility and hatchability of the eggs from the inter se and cross matings of the different varieties of Pekin ducks did not show any significant differences.

The average body weight and cumulative feed efficiency of the inter se and cross matings of the three duck species and the different varieties of Pekin showed significant differences. In general,the F1 hybrids from the inter-specific crossing were more heterotic for growth and for feed efficiency than those from the intra specific crossing.

Significant difference were also observed in the dressing percentages and ready-to-cook cut-up yields of the different mating types of ducks for both inter-specific and intra-specific hybridization. However, there seems to be no consistent differences between the F1 hybrids and their parental types.

The percentage mortality of ducklings did not differ significantly between inter se and hybrid ducklings involving the three duck species, or between inter se and hybrid ducklings involving the different varieties of Pekin ducks.
