Problems solved by technology

In the mid-alpine region of northwestern Guangxi in Guangxi, the average altitude is 800 meters, the temperature difference between day and night is large, and the rainfall is humid. There are better local chicken breeds in these areas, such as the iron-footed jute feather chicken in Nandan County, but this iron-footed chicken The low egg-laying performance of jute feather chickens restricts the development of large-scale breeding. It is necessary to select varieties. After group breeding of varieties, the feather color tends to be consistent. The annual egg production of breeders reaches 105, and the growth rate of broilers is 120. The age reaches 1.5 kg; due to lack of mating line selection, the feather color has changed, the difference has widened, and the body size is also inconsistent. The phenomenon of low egg production, slow growth and uneven body weight has not been fundamentally improved

Embodiment 1

[0029] A method for cultivating new strains of iron-footed jute feather chickens, comprising the following steps:

[0030] a. From iron-footed jute feather chickens at least 6 months old, select cocks with a body weight of more than 2.25 kg and hens with a body weight of more than 1.75 kg as male lines, and then randomly divide the male lines into A-line male lines and B-line male lines; A rooster with a weight of 1.5 kg and a hen with a weight of 1.25 kg and an annual egg production of more than 105 are used as the female line, and then the female line is randomly divided into a C-line female line and a D-line female line; iron-legged jute feather chickens at least 6 months old are crossed and Propagation, the isolated recessive white feather chicken is used as the male line of the H line;

[0031] b. Using the family breeding method, individual cage breeding, 1 cock and 20 hens form a family; A-line male, B-line male and H-line male respectively build 5 families, C-line fema...

Embodiment 2

[0051] The difference between the breeding method of the iron-footed jute feather chicken new strain of the present embodiment and embodiment 1 is the following steps:

[0052] a. From iron-footed jute feather chickens at least 6 months old, select cocks with a body weight of more than 2.25 kg and hens with a body weight of more than 1.75 kg as male lines, and then randomly divide the male lines into A-line male lines and B-line male lines; A rooster with a body weight of 1.75 kg and a hen with a body weight of 1.4 kg and an annual egg production of more than 105 are used as female lines, and then the female lines are randomly divided into C-line female lines and D-line female lines; Propagation, the isolated recessive white feather chicken is used as the male line of the H line;

[0053] c. Egg production performance selection adopts the early egg production performance identification selection method, select high-yield families and high-yield hens at the age of 32 weeks from...

Abstract

The invention discloses a method for breeding a new strain of chickens with iron feet and yellow speckle feathers and relates to the technical field of poultry breeding. The method comprises the following steps of selecting cocks with relatively large weight from the chickens with iron feet and yellow speckle feathers as paternal lines which are divided into a line A and a line B; selecting hens with relatively small weight and high egg yield as maternal lines which are divided into a line C and a line D; separating recessive white feather chickens as a paternal line which is a line H; adopting a family line breeding method to breed in a monomer cage, and adopting an independent elimination method to perform multi-character indicator selective breeding; adopting a prophase egg laying performance identification selection method and selecting a high-yield family line and a high-yield hen to breed a next generation; measuring combining ability, and respectively performing positive and negative mating measurements; matching four lines to breed a parental generation, and hybridizing the parental generation to breed the new strain of the four-hybridization chickens with the iron feet and the yellow speckle feathers. Compared with the prior art, the method for breeding the new strain of the chickens with the iron feet and the yellow speckle feathers has the advantages that the egg yield is up to 135 per year and is improved by 28.57 percent; the weight of a 110-day-old meat chicken is up to 1.5kg, and the meat chicken is taken out of a fence to be sold in the market 10 days early.

Description

technical field [0001] The invention relates to the technical field of poultry breeding, in particular to a method for cultivating new strains of iron-legged jute feather chickens. Background technique [0002] my country's local chicken breeds are rich in resources, and its meat is tender, delicious, and nutritious, and is deeply favored by consumers. In the mid-alpine region of northwestern Guangxi in Guangxi, the average altitude is 800 meters, the temperature difference between day and night is large, and the rainfall is humid. There are better local chicken breeds in these areas, such as the iron-footed jute feather chicken in Nandan County, but this iron-footed chicken The low egg-laying performance of jute feather chickens restricts the development of large-scale breeding. It is necessary to select varieties. After group breeding of varieties, the feather color tends to be consistent. The annual egg production of breeders reaches 105, and the growth rate of broilers i...
