Problems solved by technology

As a big country of goose production and consumption, in the existing technology, the sex identification of goslings in Chinese goose production has always been through the traditional anus identification, which not only causes stress and damage to goslings, is not conducive to disease prevention and control, but also increases costs.

Embodiment 1

[0018] A method for cultivating self-separated male and female geese, comprising the following steps:

[0019] (1) Screening of light brown male geese: screen the offspring of the random mating population of the white feather goose variety, and pass sensory identification to screen light brown 1-day-old male and female chicks and yellow 1-day-old male and female chicks, and mark the wing number, The light brown 1-day-old male and female chicks wear red Chinese-style wing marks, and the yellow 1-day-old male and female chicks wear green Chinese-style wing marks. When rearing in groups, the feeding conditions are exactly the same, and the brooding period is reared in three-dimensional cages. During the rearing period, the ground is raised flat, the mother goose is reared in a single cage, and artificial insemination is used for breeding; each family uses a set of semen collection and insemination equipment, which is used separately and strictly sterilized; in each growth period, ...

Abstract

The invention aims to solve the current problem of feather color auto-sexing of new meat goose breeding lines or complete set lines in the goose industry and provide a breeding method for auto-sexingmale and female gooses. The breeding method comprises the steps of screening of maple male gooses, propagation expanding of mutant groups, breeding of pure male and female parent lines and establishment of complete set lines. By adopting the method, stress and injury to young gooses are greatly decreased, prevention and control of infectious diseases of gooses are facilitated, and lots of cost forthe link of manually turning anus to distinguish male and female young gooses is saved.

Description

technical field [0001] The invention belongs to the technical field of poultry breeding, and in particular relates to a breeding method for self-separating male and female geese. Background technique [0002] With the continuous development and expansion of the goose breeding industry in my country, the problem of gender identification of newborn goslings has become prominent. Technicians always try their best to conduct detailed research on the anus and feather characteristics of goslings. At present, regardless of the parental generation or the commercial generation, it is necessary to identify the sexes of the newly hatched goslings, and treat them separately according to their respective production purposes, so as to reduce feeding costs and improve economic benefits. There are very few methods for identifying male and female goslings. Generally speaking, they can be divided into two categories. One is based on the difference in the structure of the reproductive organs o...
