Studies on the Hybridization between Domestic Drake and Domestic Goose

Abstract

An attempt was made to produce a hybrid between Domestic Drake (Anas platyrhynchos var. domestica) and Domestic Chinese Goose (Anser cygnoid var. orientalis) since, to the best of author's knowledge, it has never been produced before.
Two methods were employed for fertilization.
1. A tame drake was placed on the back of a female goose to help copulation (Figs. 3 & 4).
2. The semen obtained from the drake was diluted with Ringer's solution and was put into the oviduct of the goose by using an injector with a rubber tube at its end.
The 38 hybrid eggs were placed in the incubator and the following results were obtained.
Eggs apparently infertile…24
Eggs fertilized but the embryos died within two days…12
Embryo died after one week's development…1
Chick died soon after hatching…1
Total number…38
The chick died soon after hatching was a male and had a deformed bill (Figs. 5 & 6), but apart from this it apparently did not have any abnormal anatomical features. The incubation period of this hybrid was over 28 days which is in between those for the two parental species.
