Molecular genetic marker related to rate of teratosperm of pigs and application

Abstract

The invention provides a molecular genetic marker related to the rate of teratosperm of pigs. A molecular genetic marker site is ALGA0108896, the marker site of ALGA0108896 is located at the 24920078bp G>T mutation site in the pig NO.3 chromosome, and a pig reference genome is Sscrofa11.1. According to the molecular genetic marker related to the rate of teratosperm of the pigs, the rates of teratosperm of boars of different genotypes have significant differences, the T allele significantly reduces the rate of teratosperm, the genotype of the ALGA0108896 molecular genetic marker site can be detected to assist the breeding of the boars, homozygous boars with a low rate of teratosperm are selected and reserved, the rate of teratosperm is reduced, and the boar utilization efficiency is effectively improved.

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...
