Embodiment 1

[0037] The rapid balanced breeding method of the yellow feather blue shank powder shell layer of this embodiment, the specific operation steps are as follows:

[0038] (1) Rapid cultivation of new strains of laying hens:

[0039] Ⅰ: Breeding of pink-shell layer hen strains with 50% high-yield extra-egg lineage:

[0040] 1) Using the Ⅱ rooster as the female parent of the high-yielding laying hen Roman pink shell as the female parent and the local breed of the green shank dwarf jute feather pink shell laying hen as the male parent to produce F1 generation chickens;

[0041] 2) Using the F1 generation chickens obtained in step 1) to self-cross to generate F2 generation segregated chicken flocks.

[0042] 3) using the F2 generation of isolated chicken flocks obtained in step 2), using the green shank molecular marker to diagnose the target traits of the 1-day-old chicks of the F2 generation, and screening male and female hen individuals homozygous for the green shank egg site;

Abstract

The invention discloses a fast balance breeding method for native hen varieties, and belongs to the technical field of poultry breeding. According to the method, a hen strain with 50-percent high-egg-laying consanguinity is subjected to hybridizing matching with the hen strain with 75-percent high-egg-laying consanguinity to obtain a high-quality hen strain with 62.5-percent high-egg-laying consanguinity, the genetic negative correlation properties between the egg quality and the high-egg-laying properties can be well balanced through the high-egg-laying consanguinity contents of the matching strain, the egg laying properties are improved, meanwhile, the inherent egg quality of the native hens are maintained to the maximum degree, and the optimum high yield and high quality are realized. The progenitor male parent or female parent pure strains adopting high-yield hen variety matching combination by external consanguinity are imported, the genotype homogeneity can be favorably accelerated, the matching power of the matching strain is improved, meanwhile, a molecular marker auxiliary selection technology is adopted, the early stage selection is carried out, the generation interval is shortened, and the breeding process is accelerated.

Description

technical field [0001] The invention belongs to the technical field of poultry seed production, and in particular relates to a rapid and balanced breeding method for soil breed laying hens. Background technique [0002] With the improvement of people's living standards, the concept of consumption has changed from the quantity type to the quality type in the past, and people have higher and higher requirements for the quality of eggs. varieties (supporting lines). Local chicken breeds in my country are widely distributed, with a large number and good egg quality, but their growth rate is slow, their egg production is low, their feed conversion rate is low, and their feeding costs are high, so they are not suitable for industrialized development; The conversion rate is high, but the ratio of egg yolk to egg white is small, the egg is heavy, and the flavor is poor, which does not meet the consumption habits of our country. Therefore, improving the production efficiency of loca...
