Embodiment Construction

[0015] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0016] refer to figure 1 , a breeding method for self-sexing of the precocious and superior type yellow shank chickens described in the present invention. Generation selection process of breeding materials: according to the characteristics of feather speed inheritance and quantitative trait heritability, family selection method combined with individual selection The method, comprehensive index selection and evaluation combined with individual phenotypes, assisted by the application of feather speed molecular breeding technology, determined the core group, and formed a family for the selection and breeding of specialized strains.

[0017] Pure line: The pure line inc...

Abstract

The invention provides an auto-sexing breeding method of early-maturing excellent type yellow-shank partridge chickens. The method comprises the steps that a Qingyuan partridge chicken rapid-feathering line which grows fast in early stage, a Qingyuan partridge chicken slow-feathering line which has prominent reproductive performance and a Guangxi partridge chicken rapid-feathering line are adopted, the grandparent generation selects cocks and hens of the Qingyuan partridge chicken rapid-feathering line, the paternal line selects cocks of the Qingyuan partridge chicken slow-feathering line, and the maternal line selects hens of the Guangxi partridge chicken rapid-feathering line; the parent generation selects cocks of the Qingyuan partridge chicken slow-feathering line, and the female parent selects yellow-shank slow-feathering hens produced by hybridizing the cocks of the Qingyuan partridge chicken slow-feathering line with the hens of the Guangxi partridge chicken rapid-feathering line; for slow-type early-maturing excellent yellow-shank partridge chickens, the cocks are slow-feathering cocks, the hens are rapid-feathering hens, and autosexing is achieved according to the feathering speed. Compared with traditional Qingyuan partridge chickens, commercial generation autosexing according to the feathering speed is achieved, the market age of the hens is 10 days ahead of schedule, the egg laying performance of the parental generation can be improved by 15% or above, the feed conversion rate is decreased by 0.2, and the breeding profit is increased.

Description

technical field [0001] The invention relates to the technical field of poultry genetics and breeding, and to the technical field of supporting slow-speed super-high-quality hemp-feathered broiler chickens, in particular to a breeding method for self-sexing of early-maturing and super-high-quality yellow-shank hemp chickens. Background technique [0002] Domestic and foreign broiler matching lines are mainly composed of fast large white-feather broiler chickens and high-quality yellow-feather broiler chickens. The pursuit of high-quality, delicious and safe poultry products has become the mainstream of consumption, and the breeding of different types of high-quality chickens has become an important pillar of a strong national seed industry. Qingyuan Ma Chicken is the first high-quality famous chicken in Guangdong Province, and its long-term sales volume ranks first in the high-quality chicken market in Guangdong, Hong Kong and Macao. [0003] Before breeding, Qingyuan chicke...
