Breeding pig offspring hair color prediction method based on haplotype MC1R*31 gene

Abstract

The invention discloses a breeding pig offspring hair color prediction method based on a haplotype MC1R*31 gene. The breeding pig offspring hair color prediction method comprises the following steps of detecting at least one of a 661bp site, a 721bp site and a 781bp site of the haplotype MC1R*31 gene of a male parent and / or female parent breeding pig, and accurately predicting offspring hair color of a specialized line and a new variety (commercial line) based on a plurality of sites of the MC1R*31 gene. thereby ensuring the black hair color of the bred offspring breeding pigs. Compared with a traditional breeding technology, the method has the advantages that the breeding period can be rapidly shortened, the breeding cost of the breeding pigs can be reduced, and the consistency and economic value of the hair colors of the offspring breeding pigs or commercial pigs can be improved.

Description

[0001] This invention is a divisional application filed by the applicant based on another invention patent that he previously applied for. The application number of this invention patent application is: 201911066191.0, the application date is: November 4, 2019, and the invention name is: a Breeding method of pure black hair color pig breed. technical field [0002] The invention relates to a method for predicting the coat color of offspring of breeding pigs, more specifically, the invention mainly relates to a method for predicting the coat color of offspring of breeding pigs based on the haplotype MC1R*31 gene. Background technique [0003] In the past few decades, the genetic improvement of pigs has mainly focused on improving the carcass performance such as growth rate and lean meat percentage, ignoring the improvement of pork quality, which has led to a sharp decline in meat quality while the carcass performance of pigs has been greatly improved. Taste worse. With the d...

Problems solved by technology

[0007] One of the objectives of the present invention is to address the above-mentioned deficiencies and provide a method for predicting the offspring coat color of breeding pigs based on the haplotype MC1R*31 gene, in order to solve the problem that the breeding method of similar breeding pigs in the prior art cannot accurately predict the separation of offspring coat color. Lead to low efficiency and affect technical issues such as the selection of specialized strains and the breeding process of new varieties (matching lines)
