Domestic and foreign geese are rich in species resources. Different geese species have their own different characteristics and uses. Developing economic hybrids of geese and making full use of heterosis to produce commercial geese is one of the important measures to increase the economic benefits of geese. To carry out the economical hybridization of geese, we must pay attention to the following issues:
Pay attention to the choice of male and female parents
The female parent used for crossbreeding requires that the number of populations be large to save on the introduction cost and facilitate the popularization and promotion of hybrid technology. Second, the reproductive performance is better, and the number of eggs produced is higher to reduce the production cost of hybrid generation goose seedlings; Individuals should be relatively small in order to save feed and reduce the production cost of breeding geese. The male parents used for crossbreeding should select individuals or strains with large individuals, fast growth rates, high feed utilization rates, and good meat quality. In addition, the parent and female parent used for cross-breeding should be located farther away from each other, and the source difference should be large, so that the heterosis of the hybrid offspring will be obvious and the complementation of hybridization will be stronger.
Emphasizing on the implicit relationship between feathers of hybrid offspring
The sale of goose feathers is one of the important income increase methods in goose and goose product processing. Due to the high market price of white goose feathers, the male and female parent feather color selection should be emphasized in the crossbreeding, so that the hybrid product goose can be produced in white. Uniform feathers.
Recommend several suitable cross parents
Parents: Sichuan white goose, Huoyan goose, Northeast goose, Taihu goose. The first three are goose species with large egg production in small and medium-sized goose breeds in China. Although the egg production of Taihu Goose is not the highest, its individuality is small and the cost of feeding is low. The effect of mating as a female parent is significant.
Paternal: Rhine geese and white geese. Using Rhine geese as a male parent, crossbreeding with our country's small and medium sized goose breeds can significantly improve the insufficiency of individual geese species and slow growth in China. The West Anhui White Goose has good down quality and is a medium-sized goose species. It can be used as a male parent to crossbreed with local small and medium-sized goose species in China to produce both wool and meat-type commodity goose.
