To carry out the economical hybridization of geese must pay attention to the following two issues:
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 breeding performance is good, and the number of eggs produced is large, so as to reduce the production cost of hybrid generation goose seedlings; 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 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
Mother: 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.
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.

Mini Camera Introduce
1. Wired camera
The advantages are that the technology is mature, the industrial Network Camera technology is directly transplanted, the signal interference is not feared, and it is stable and reliable;
The disadvantage is that the installation is complex and requires wiring. It can only be accessed through a computer. The scope of use is limited and it is not suitable for home use.
2. Wireless camera
The advantages are that there is no need for wiring, the installation and increase of cameras are relatively convenient, and the cost of Internet access is low;
The disadvantage is that it will be interfered by the signal, which may affect the definition and transmission speed of the picture.
Extended data
Now the technology of solar energy monitoring is mature, and solar energy can be used to solve the problem of power supply. Outdoor monitoring can also choose more advanced solar energy monitoring. Remote monitoring without power and network is no longer an imagination.
1. Simple installation: install by yourself without inviting construction personnel;
2. Adjustable angle: 360 degree rotation, no dead angle monitoring;
3. No electricity connection: solar power generation and built-in lithium battery power supply;
4. No wiring: no wall chiseling or decoration damage.
matters needing attention
The configuration of the solar power supply system requires the customer to provide the total power consumption of each load equipment,
It is necessary to know the local lighting conditions and the duration of continuous operation of the equipment
