(1) Grouping and grouping Grouping means rearranging the group; grouping means raising the male and female geese separately after grouping. When the egg-laying rate of the goose group drops below 5, it indicates that the breeding geese will enter a long rest period. Breeding geese are generally eliminated after 3 to 4 years, but every year during the break of production, the female geese that are disabled, sick, or with low egg production must be eliminated, and the male geese with poor egg production must be eliminated in proportion. At the same time, in order to enable the male and female geese to smoothly reach the best body condition after the rest period, ensure a higher fertilization rate, and ensure the convenience of live plucking and subsequent management, the male and female geese should be placed in the group after the breeding geese are formed. Raised in groups.

(2) Forced moulting is generally done by stopping artificial light, stopping feed for 2 to 3 days, providing only a small amount of green feed, and ensuring adequate drinking water. ; On the 4th day, start feeding green roughage consisting of green material plus bran residue, etc., and try to pull out the main and secondary wing feathers around the 10th day. If the test is not difficult, the feather roots are dry, and they can be pulled out one by one. Otherwise, it should be pulled out after 3 to 5 days, and finally the main tail feathers should be pulled out. Under the conditions of large-scale breeding, forced moulting of geese is usually combined with live down plucking. That is, after the whole group and grouping are completed, forced moulting is used for about a week, and then the live down plucking operation is started. . After plucking the feathers, the geese should be kept in the sports ground and fed with food and water. The geese should not be allowed to go into the water to prevent bacterial infection and inflammation of the pores. For a period of time after feather plucking, due to its poor adaptability, it should be protected from stress such as rain and scorching sun exposure. Generally, live down plucking can be performed again after 7 weeks. This can improve economic benefits and make the goose flocks neatly produced, which is convenient for management.
The geese after plucking their feathers must be kept in captivity and are prohibited from being exposed to water, rain, and sunlight
(3) Breeding geese entering the rest period should be mainly grazed, and the geese during the laying period should be kept in captivity. The purpose of changing the diet to a rearing period diet is to consume the fat in the mother geese, improve the geese's ability to tolerate rough feeding, and reduce feeding costs. The geese that are raised in large-scale housing must adopt maintenance period feeding and management methods.
