Method for Purification and Conservation of Original Lion Head Goose

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 technique for purifying and breeding Lion's Head Goose, in particular to a method for purifying and preserving the original species of Lion's Head Goose. Background technique [0002] Since the reform and opening up, the breeding volume of Raoping Lion's Head Goose has increased year by year. In 2013, the number of breeding geese in the county was 58,850 (including 11,260 male geese), including 40,100 original breeding geese in the six towns of Fubin, Zhangxi, Lianrao, Gaotang, Huanggang, and Qiandong (including 7,400 male geese); The number of meat geese in the county is 1.684 million, of which 763,000 are the original breed of meat lion geese in the above-mentioned six towns. Specialization in raising geese has been formed. According to the survey, there are 486 professional households in the county that raise more than 100 original breeding geese, 225 households that raise more than 200 geese, and 4 households that raise ...

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
