Embodiment 1

[0031] Embodiment 1 Yellow Feather Broiler AH Population Uniformity Breeding Method

[0032] The AH population of yellow-feathered broilers is parented from high-quality broiler line A and Huiyang bearded chickens, and the distant cross F 2 Design build. In this embodiment, a total of 582 genotyped individuals were used, among which F 0 Generation 20, F 1 Generation 51, F 2 Generation 511 only. f 2 The offspring came from 8 half-sib families, all of which had body weight records at 91 days of age. Genotyping was done in Canada using chicken 60K SNP arrays. The quality control uses the following criteria: delete the markers with Call rate less than 95%, Gentrain score less than 0.6 and MAF less than 0.01. After quality control, 46672 SNP markers were retained. This method is implemented according to the following procedure:

[0033] (1) The body weight file data of 10 yellow-feathered broilers were sorted out, and the sorting format is shown in Table 1.

Embodiment 2

[0051] Embodiment 2 simulation broiler data uniformity breeding method

[0052] In order to illustrate the effect of the long-term selection of the method of the present invention, simulated broiler data is used as an example.

[0053] The simulation data is generated by QMSim software (http: / / www.aps.uoguelph.ca / ~msargol / qmsim / ), through simulating historical population (historical population) for 1000 generations, from 400 chickens (200 roosters + 200 hens chickens) gradually expanded to 3000 chickens (1500 roosters + 1500 hens). The current population has 10 generations, and the population size of each generation is 30,000 chickens. In each generation, 1650 breeder chickens (150 roosters + 1500 hens) were selected, and the male and female were mated randomly at a ratio of 1:10. Only one hen can hatch and produce 20 healthy chicks. The data used in the analysis were the data of 10 generations of the current group.

[0054] Assume that the target body weight heritability i...

Abstract

The invention discloses a high-uniformity breeding and seed reserving method of yellow-feather chicken and relates to the technical field of poultry breeding. The method includes measuring weight of achicken flock, estimating individual breeding value of the chicken flock, building individual selection index of uniformity, selecting individual chickens reserving as seeds, and the like. Accordingto the method, the breeding value is estimated based on the weight of yellow-feather chicken, the individual selection index model is established, and the individual selection index is calculated fordetermining the individual chicken reserving as seeds. Weight increase can be regulated according to weight regulation parameter, so as to be adaptable to change in market requirement. The high-uniformity breeding and seed reserving method of yellow-feather chicken meets requirements on uniformity breeding and seed reserving of yellow-feather chicken, and can improve the uniformity of the chickenflock on the basis of controlling increase of growth speed.

Description

technical field [0001] The invention relates to the technical field of poultry breeding, in particular to a method for selecting and retaining yellow-feathered broilers with high uniformity. Background technique [0002] In the breeding of white-feathered broilers, growth speed is one of the core breeding goals. Yellow-feathered broilers are different from white-feathered broilers. Yellow-feathered broilers do not pursue a rapid increase in growth speed; on the contrary, excessive growth speed will seriously affect the economy of yellow-feathered broilers Value, there are two reasons: First, if the yellow-feathered broiler chickens are listed according to the conventional market age, the growth rate will be too fast, which will lead to excessive body weight of the chickens, which does not meet the current consumer market requirements for the market weight of yellow-feather broiler chickens. The economic value of broiler chickens is greatly reduced; secondly, if the weight is...
