Problems solved by technology

Due to the interference of environmental factors, traditional phenotypic selection has the problem of inaccurate selection
Moreover, the traditional breeding methods all need to measure the phenotypic value of the individual, the breeding process is long, and the breeding cost is high

Embodiment 1

[0044] Example 1. Verification of the correlation between the SNP marker rs317682933 and the body weight and feed intake of Lueyang black-bone chicken

[0045] 1. Test animals

[0046] Lueyang black-bone chickens are randomly selected from three generations of Lueyang black-bone egg breeding core group bred by Lueyang Longjia Agricultural Science and Technology Development Co., Ltd. All Lueyang black-bone chickens are hatched in the same batch and raised in the same chicken house. 40pcs / m 2Cage brooding; brooding temperature is 33-35°C in the first week, then lowered by 2-3°C every week, and removed from the temperature in the fourth week; the light time is 22h in the first week, and then reduced by 1-1.5h every week, using Huaqin 911A egg chicks were fed with compound feed. In 60 days, they were transferred to the laying hen house and raised in individual single cages.

Embodiment 2

[0081] Embodiment 2, the comparison of the breeding effect of traditional phenotype selection and marker-assisted selection

[0082] 1. Test animals

[0083] 500 hens and 200 roosters were randomly selected from the second generation of egg-line breeding core group raised by Lueyang Longjia Agricultural Science and Technology Development Co., Ltd. to form a traditional phenotype selection breeding group, and another 500 hens and 200 roosters were selected SNP marker-assisted selection breeding population.

[0084] 2. Test plan

[0085] Traditional phenotype selection is based on 12-week-old body weight, and individual phenotype selection is adopted. The top 5% of cocks are sorted by 12-week-old body weight, and the top 5% of hens are reserved for 25%. The marker-assisted breeding method not only considers the body weight at 12 weeks, but also considers the genotype of the rs317682933 locus, and the proportion of reserved seeds is the same as that of the traditional breeding ...

Abstract

The invention discloses an SNP marker related to growth traits of black-bone chickens and an application thereof. The invention firstly provides an application of a substance for detecting polymorphisms or genotypes of an SNP marker rs317682933 in identification or auxiliary identification of chicken body weight. The SNP marker rs317682933 is the 73209189th nucleotide of 4th chromosome located ingalGalGal6-edition chicken genome, and the alleles of the marker are C and T. The invention further provides a method for identifying or assisting in identifying chicken body weight. The invention discovers that; when the genotype of the SNP marker rs317682933 in the chicken genome is CC, the body weight is larger than that of chickens whose genotype is CT, and the correlation between the marker and the body weight is gradually enhanced along with the increase of the age of the chickens. Therefore, the application of the SNP marker rs317682933 in the growth performance breeding of the Lueyangblack-bone chickens can improve the selection accuracy, increase the selection reaction and shorten the breeding process.

Description

technical field [0001] The invention relates to the field of molecular marker assisted breeding, in particular to a SNP marker related to the growth traits of black-bone chicken and its application. Background technique [0002] Lueyang black-bone chicken is a unique poultry breed in Shaanxi Province, and it is also a larger black-bone chicken among the existing black-bone chickens in China. The variety has tender meat, delicious taste, rich nutrition and health care functions. Poultry products are deeply loved by consumers, and the development of the black-bone chicken industry has a good market prospect. However, because Lueyang black-bone chicken has not been systematically selected, this variety also has the disadvantages of slow growth, high feed-to-meat ratio, and poor uniformity. The average body weight of Lueyang black-bone chickens at 12 weeks old is 1.38±0.19 kg, and the average weight of hens is 1.04±0.13 kg; the feed-to-meat ratio of roosters at 12 weeks is 7.0...
