Problems that Must Be Paid Attention to in Economic Hybridization of Goose
Pay attention to the choice of male and female parents
The female parent used for crossbreeding has a large number of populations to save the cost of introduction and facilitate the popularization and promotion of hybrid technology. Second, the reproductive performance is good, and the number of eggs produced is large to reduce the production cost of hybrid generation goose seedlings; To be relatively small in order to save feed and reduce the production costs 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 the origin and the source difference is large, so that the heterosis of the hybrid offspring will be obvious, and the hybrid complementation 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 products processing. Because the white goose feather market price is high, the male and female parent feather color selection should be emphasized in the cross combination to enable the production of the hybrid commodity goose White feathers are uniform.
Recommend several suitable cross parents
The mother of Sichuan white goose, Huoyan goose, goslings, Taihu goose. The first three are the goose species with the most egg production in China's medium and small geese. Although the egg production rate 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.
The father of the Rhine Goose and West White Goose. 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.
The advantages of food additives are these followed:
1. Improve the appearance of food.
2. Keep and enhance the nutrition value of food.
3. Increase the variety and conveniences of food.
4. Miantain freshness and prolong shelf life.
5. Provide leavening or control acidity and alkalinity.
Breeding Goose Hybrids
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.
