Pig sperm malformation rate related molecular genetic marker and application thereof

Abstract

The invention provides a pig sperm malformation rate related molecular genetic marker. The molecular genetic marker site is H3GA0014627, wherein the H3GA0014627 marker site is the 123567821th bp position of the No.4 chromosome of boar, the 123567821th bp position is a mutation site with C being greater than T, and the pig reference genome is Sscrofa11.1. The molecular genetic marker is used for marking boars of different genotypes. The sperm malformation rate has significant difference, T allele significantly reduces the sperm malformation rate, can assist the breeding of boars by detecting the genotype of the H3GA0014627 molecular genetic marker site, selects homozygous boars with the low sperm malformation rate, and reduces the sperm malformation rate, thereby effectively improves the utilization efficiency of the boars.

Description

technical field

[0001] The disclosure belongs to the field of molecular genetic biotechnology, and in particular relates to a molecular genetic marker related to the malformation rate of pig sperm and its application. Background technique

[0002] Artificial insemination (AI) has been applied in my country since 1954. After decades of technical improvement and integration and national support, artificial insemination technology is becoming more and more mature in my country, and its application in large and medium-sized farms is also basically popular. The advantage of artificial insemination is that it not only improves the utilization rate of good boars, but also timely detects and records the quality of boar semen. At the same time, the health status and reproductive potential of boars can be monitored through the evaluation of semen quality, so as to optimize the individual genetic potential and maximize the reproductive capacity.

[0003] In the process of artificial i...
