Embodiment 1

[0016] Breeding method for new strains of recessive white and colored feather iron-footed chickens, such as figure 1 As shown, the steps include:

[0017] a. Taking Gushi chicken as the male parent and AA chicken CD as the female parent, crossbreed to produce F1 generation, and select hens with jute feathers and black / blue shank characteristics and cocks with jute feather characteristics in the F1 generation;

[0018] b. The male and female individuals selected by the F1 generation are cross-crossed and multiplied, and grouped according to the feather color, and the beneficial traits such as fast growth and high egg production performance are purified and fixed according to the family and individual selection methods. After more than 4 generations After the breeding of 4 groups of broiler chickens, the new lines of jute feather, white feather, black feather and reed flower were bred. During the breeding process, we should also pay attention to the characteristics of sexual ma...

Abstract

The invention relates to a method for cultivating a new strain of recessive white and colored feather tiejiaoma broilers, and belongs to the technical field of poultry breeding, which comprises the following steps of: a, hybridizing to generate a F1 generation by taking parental CD of a broiler chicken from another country as a female parent and a tiejiaoma broiler with characteristics of black / green shins, jute feathers and white skins as a male parent, selecting and remaining F1-generation hens with the characteristics of the jute feathers and the black / green shins and F1-generation cocks with the characteristics of the jute feathers; and b, crossing male and female individuals selected and retained in the F1 generation athwart and propagating, grouping respectively according feather colors I, purifying and fixing beneficial characters according to a family and individual selection method, breeding by more than four beneficial characters for generations to cultivate new strains of four groups of broilers with jute feathers, recessive white feathers, black feathers and striped feathers. In the method, the high-productivity bloodlines of the broiler chickens from other countries is guided into the varieties of the tiejiaoma broilers successfully, the growth speed and egg-laying performance of the tiejiaoma broilers in China are improved substantially, and the genetic progress with large economic characters can be obtained within a short time.

Description

Technical field [0001] The present invention belongs to the field of poultry breeding technology, which involves a set of cultivation methods for the new department of hidden white and non -ferrous iron -footed hemp chickens. Background technique [0002] In recent years, at home and abroad, high -quality meat chickens have paid more and more attention and have conducted a lot of research.However, there is a different understanding of the issue of "what is high -quality meat chicken".In foreign countries, high -quality meat chickens are basically only for the so -called quality.For feathers, it mainly considers whether it affects the appearance of the carcass after slaughtering, so it prefers white feathers; for the tibia, the main considering whether the tibia can support the rapidly growing body.As for which kind of feathers and tibial chickens are better, they don't seem to be interested. [0003] Chinese and overseas Chinese consumers pay more attention to nutrition and taste...
