Embodiment 1

[0031] A kind of breeding method mainly used as the special male parent strain of yellow-feathered broiler chickens, the steps are as follows:

[0032] Step 1. Use Hong Kong jute pure line rooster as the male parent, and broiler chicken AA parent CD as the female parent, crossbreed to produce F1 generation, F1 generation contains 50% of AA parent generation CD lineage, F1 generation will appear For a small amount of jute feather-colored individuals and more white-feather individuals, select and retain the F1 generation jute-colored individuals, and carry out feeding and management according to the breeder breeding management method;

[0033] Step 2, male and female individuals of F1 generation jute feather color are cross-fixed and multiplied. In this process, in addition to producing jute feather individuals, recessive white feathers, reed flowers, gray feathers, and black feather individuals will be separated, and the above-mentioned Individuals of various coat colors are gr...

Embodiment 2

[0037] A kind of breeding method mainly used as the special male parent strain of yellow-feathered broiler chickens, the steps are as follows:

[0038] Step 1. Use Liangfenghua parent rooster as the male parent, and use the Kebao ancestor D line as the female parent to produce the F1 generation. The F1 generation contains 50% of the Kebao D lineage, and a small amount of jute feather color will appear in the F1 generation Individuals with more white feathers and individuals with more white feathers, select individuals with jute feather color in the F1 generation, and carry out feeding and management according to the feeding and management methods of breeders;

[0039] Step 2, male and female hens of F1 generation jute feather color are crossed. In this process, in addition to producing jute feather individuals, recessive white feathers, reed flowers, gray feathers, and black feather individuals will be separated, and jute feather individuals and hidden individuals will be separat...

Abstract

The invention belongs to the technical field of poultry breeding. The invention provides a method for breeding a high-quality broiler strain with higher production performance, recessive white feathers and colored feathers. The method comprises the following steps: 1. taking the foreign broiler chicken as female parents and yellow-feathered broilers with the characteristics of jute feathers and yellow shins as male parents to hybridize to generate F1 generation, selecting and reserving the individuals with jute feathers in the F1 generation, and feeding and managing the individuals in the ways of feeding and managing the breeding chicken; 2. carrying out athwart crossing and propagating on the obtained male and female individuals with jute feathers in the step 1, grouping the generated individuals respectively according to the feather colors, carrying out test crossing on the groups of individuals with other feather colors except the group of individuals with white feathers, and then purifying and fixing the beneficial characters of the groups according to the family and individual selection methods; and 3. forming the new strain with the foreign broiler chicken bloodline through systematic breeding of four or more generations of chicken. The method has the beneficial effects of substantially improving the early growth speed of the yellow-feathered broilers in China and more obviously reducing the feed-gain ratio.
