A molecular marker and screening method and application related to reproductive traits of sows

Abstract

The invention relates to a molecular marker related to reproductive traits of sows, a screening method and application thereof, and relates to the technical field of pig genetics. The molecular marker is a SNP molecular marker, which is located at the 96673697bp position of pig chromosome 1 or the 58587289bp position of pig No. 10 chromosome. The pig reference genome is Sscrofa11.1; the 96673697bp position of pig chromosome 1 is the mutation site of C>T mutation, and pig No. 10 Chromosome 58587289bp is the mutation site of C>T mutation. The reproductive traits of sows with different genotypes of this molecular marker have very significant differences. Selecting sows based on this molecular marker can retain sows with high total number of litters and total number of live piglets, which is conducive to improving the reproductive traits of sows and increasing the number of sows. Sow farrowing performance.

Description

A molecular marker and screening method and application related to reproductive traits of sows technical field The present invention relates to the technical field of pig genetics, particularly relate to a kind of molecular marker relevant to sow reproductive traits. Note and screening methods and applications. Background technique my country has a long history of raising pigs, and the end product of raising pigs is mainly pork, which is the most common meat system in daily life. The output ranks first in meat products. In actual breeding work, total litter size and litter size are the most important factors in assessing sow production. It is also one of the important reproductive and economic traits of sows, which directly affects the economic benefits of pig farms. affect mother The factors of pig reproductive performance include breed, age, environment, feeding management, hormone level, nutrition and genetics, of which genetics is the main factor. Factors, la...

[0003] The reproductive traits of pigs are controlled by multiple genes. The traditional QTL mapping method is suitable for the study of rare genes and the population can be controlled. The purpose and results are highly predictable. Loci where parents differ in segregating populations with no detection of multiple alleles and low mapping resolution
