Embodiment 1
[0036] In this embodiment, Hetian black chicken and Babcock B380 are used as materials to cultivate a commercial male and female dual-purpose high-quality white-feathered chicken mating line with five-toed traits.
[0037] A method for cultivating high-quality chickens with both meat and eggs, comprising the following steps:
[0038] Step 1: Breeding White Feather Quick Feather Sire with Five-toed Trait
[0039] (1) Selection of Babcock B380 hens
[0040] Select fast-feather white-tailed B380 hens as breeding materials.
[0041] (2) Choice of Hetian black chicken
[0042] Select black-feather, fast-feather, and single-comb roosters with five-toed traits.
[0043] (3) hybridization
[0044] The cock in the step (2) is crossed with the hen in the step (1), and the hybrid offspring with the five-toed trait and the whole body white feather trait are selected as the F0 generation.
[0045] (4) Cross propagation and molecular marker-assisted selection
[0046] The F0 generation ...

Abstract
The invention discloses a method for breeding high-quality white-feathered chickens with both meat and eggs, comprising: step 1, white-feather fast-feather male line selection: use white-tailed fast-feather Babcock B380 as the female parent, and black chickens with five-toed or rose-crown traits Feather fast feather Hetian black chicken is used as the male parent to cross, and the white feather fast feather male line is bred; Step 2, the black feather slow feather female line is selected: the black tail slow feather Babcock B380 with the recessive white locus as the wild type homozygote is The female parent, the black feather slow feather and Tianhei chicken are used as the male parent to cross, and the black feather slow feather female line is bred; step 3, the white feather fast feather male line selected in step 1 and the black feather slow feather female line selected in step 2 are crossed to produce meat Commercial seedlings of high-quality white feather chickens with both eggs and eggs. The present invention utilizes the epistasis effect of the dominant white gene locus on black feathers, and the bred commercial products are white feathers, and the feather marrow does not contain pigment, which is more suitable for slaughtering and marketing; at the same time, the breeding method speeds up the breeding process, and can effectively avoid specialized laying hens and chickens. Uncertainty or cyclical risks in the broiler chicken consumption market.
Description
technical field [0001] The invention relates to the technical field of poultry breeding methods, in particular to a method for breeding high-quality white-feathered chickens with both meat and egg functions. Background technique [0002] Babcock B380 is a medium-sized high-yield laying hen bred by Isa company in France, without nesting ability. The commodity generation Babcock B380 is 50% white-tailed red feathers and 50% black-tailed red feathers; 50% is fast-feather individuals and 50% is slow-feather individuals. Blue brown, Jinghong, Hailan gray, Bai Laihang, Roman, etc.) do not have. Babcock B380 black-tailed individuals are often directly used for crossbreeding with fast large colored cocks to produce colored feather broilers. The broilers produced in the above manner contain pigments in the feathers, and after slaughtering, there will be pigment residues in the skin pores, which will affect the appearance of the carcass, which is very unfavorable for slaughtering an...
