Method for cultivating dwarf-type black leg pockmarked plume chicken strains

Abstract

The present invention relates to an excellent-quality chicken maternal strain, in particular to a method for the strain breeding of the dark-shank spotty plumage chicken with dwarf gene, which belongs to the technical field of the dark-shank spotty plumage chicken with dwarf gene. The breeding procedures of the present invention are (1) selecting a cock of Chongren chicken and a hen having the dark-shank partridge in the grandparent hen group of the dwarf yellow-feather chicken as the breeding materials and selecting a normal-shaped cock having the dark-shank partridge character in the F1 generation after the hybridization of the cock and the hen; (2) Selecting the dark-shank partridge normal-shaped cock to be mated with the hen of the dark-shank partridge dwarf yellow-feather chicken and selecting the dark-shank partridge dwarf cock and the dark-shank partridge dwarf hen in the F2 generation; (3) cross-breeding and locking the selected dark-shank partridge dwarf cock and the dark-shank partridge dwarf hen so as to get the present invention after the breeding from generation to generation. Since the body of the maternal-strain chicken is short cultivated through the present invention, the chicken has the outstanding advantages of precocious puberty, high-yield of eggs and less feed consumption and cultivated space saving, which greatly reduces the production cost of the commodity generation chicken and improves the comprehensive benefit of the cultivation.

Description

technical field [0001] The invention relates to the technical fields of animal husbandry and poultry genetic breeding. In particular, it relates to the technical field of a breeding method for a high-quality chicken female strain and a dwarf green shank hemp feather chicken. Background technique [0002] At present, the high-quality chicken market in my country is developing rapidly, especially the high-quality chicken with green shins and hemp feathers is favored by consumers, and the market prospect is extremely broad. At present, in the crossbreeding of high-quality chickens with blue-shined hemp feathers in China, due to the lack of high-yield and low-consumption blue-shined hemp-feathered female parent strains, local chicken breeds with blue-shined hemp feathers are generally used as the first male parent after crossing with recessive white feathers. , to produce F 1 The hen is used as the second female parent, and another rooster with green shanks and hemp feathers i...
