Method for refinement and breed conservation of stock lion-head geese

Abstract

The invention provides a method for refinement and breed conservation of stock lion-head geese. The method mainly comprises the steps that breed geese with the same or similar appearance of the stock lion-head geese are selected to build a selective breeding basic group; an atretic selective breeding core group is selected and remained; after feeding and management of four to six months to a single-column small water body goose house and selective breeding of four to five generations, reserved breed geese with outstanding appearance features such as obvious sarcomas, wax-like leg skin, large abdominal girths and pure feathers are finally selected as a first generation; on the basis, refinement and rejuvenation are carried out; and finally, a stock parent generation group of line-head geese with excellent production performance can be selected for breeding. The selective breeding mainly aims to protect stock resources of the lion-head geese, prevent variety degeneration caused by chaotic hybridization, achieve further stabilization of economic traits of the unique stock lion-head geese in China, enhance genetic performance of the geese and achieve industrialization of the stock lion-head geese.

Description

Technical field [0001] The invention relates to a technology for purification and breeding of lion head goose, in particular to a method for purification and breeding of original lion head goose. Background technique [0002] Since the reform and opening up, Raoping's lion-head geese has increased year by year. In 2013, the county's stock of geese was 58,850 (including 11,260 male geese), among which 40,100 original geese (including 7,400 male geese) were in Fubin, Zhangxi, Lianrao, Gaotang, Huanggang, and Qiandong; There are 1.684 million meat geese in the county, of which 763,000 are the original meat lionhead geese in the above six towns. The specialization of goose raising has taken shape. According to the survey, there are 486 specialized households raising more than 100 original breed geese, 225 households raising more than 200 geese, and 4 households raising more than 1,000 geese. There are 8 specialized goose farming villages, among them, the "Qianrenjia" natural villag...

AI Technical Summary

Problems solved by technology

[0003] At present, the main problems of lion head goose breeds are: ①The original species rate is not high

④ Slow progress in strain selection

Although the breeding of the original lion head goose of the heavy multi-egg series was approved by the national, provincial and municipal science and technology authorities as early as 1998, it was forced to stop in 2002 due to lack of special research funds, aging and replacement of professional technical forces.

On the other hand, the correct method of perennial artificial breeding by holding big goose competitions is basically lost
