Abstract

The invention provides an SNP molecular marker located on a pig chromosome 14 and related to the dead fetus number and the healthy birth rate of a sow and application of the SNP molecular marker. The locus of the SNP molecular marker corresponds to T-exceeding-C mutation at the 109497913bp position on the 14 chromosome of the version 11.1 of an international pig reference genome. The molecular marker is obtained through whole genome correlation analysis, and the characters of the dead fetus number and the healthy birth rate of the sow can be remarkably influenced. The invention further provides a primer pair for detecting the molecular marker. An efficient and accurate molecular marker assisted breeding technology can be established through the molecular marker and the primer pair and applied to character genetic improvement of the dead fetus number and the healthy birth rate of the sow, and therefore the dead fetus number of the sow is decreased, the healthy birth rate is increased, and then the reproductive performance of the reproductive sow is improved.

Description

technical field

[0001] The invention relates to a SNP molecular marker which is located on the No. 14 chromosome of pigs and is related to the number of stillbirths and the healthy litter rate of sows and its application. Background technique

[0002] The reproductive performance of sows directly affects the economic benefits of breeding enterprises, and the number of stillbirths and healthy litter rate, as important economic traits of sows, is an important indicator to measure the reproductive performance of sows. As we all know, the number of stillbirths is negatively correlated with the healthy birth rate, the lower the number of stillbirths, the higher the healthy birth rate. Therefore, reducing the number of stillborn sows and improving the healthy litter rate of sows has always been the main goal of breeders. However, the number of stillbirths and the rate of healthy babies are traits of low heritability and are easily affected by environmental factors. Therefore, the...
