Embodiment 1

[0039] In this example, refer to figure 1 , screened for molecular markers associated with piglet mortality by the following methods.

[0040] 1. Pig data collection

[0041] (1) Collection of phenotypic data

[0042] The pigs used in the present invention to record phenotypic data are 6073 healthy sows from Guangxi Yangxiang Co., Ltd., and the breeds include: Dabai, Landrace and Duroc. The pedigree information used in this study included the pedigree information of these 6,073 sows, involving 35,313 individuals. Data included total litter size, total deaths, stillbirths, and mummies. Among them, the total number of deaths is equal to the number of stillbirths plus the number of mummies. The mortality trait studied in the present invention is the percentage of total deaths to total litter size.

[0043] (2) Genetic data collection

[0044] Pig ear tissue was used for DNA extraction, and all samples were stored in a -20°C freezer until then. DNA was extracted using the k...

Abstract

The present invention proposes a SNP marker related to piglet mortality, the SNP marker is selected from the 404th nucleotide of the nucleotide sequence shown in SEQ ID NO: 1, which is a base C or T. The use of this molecular marker can accurately predict the difference in mortality traits between pigs of different genotypes, and can accurately and efficiently select excellent pig breeds with good reproductive performance of sows. It is simple, fast, highly sensitive and specific. advantage. In pig breeding work, this molecular marker can be used as a reliable marker of mortality traits, which is convenient for early selection, thereby shortening the generation interval, improving the selection intensity, and improving the efficiency and accuracy of selection.

Description

technical field [0001] The present invention relates to SNP markers and their applications. Specifically, the present invention relates to the porcine GATB gene as a molecular marker related to piglet mortality and its application. More specifically, the present invention relates to SNP markers associated with piglet mortality and uses thereof. Background technique [0002] With the improvement of the living standard of Chinese residents, people's demand for meat food is gradually increasing. Driven by the growing demand for meat, my country's aquaculture industry has grown rapidly. The white paper "Food Security in China" released on October 14, 2019 shows that the per capita possession of pigs, cattle and mutton in China in 2018 was 46.8 kilograms, an increase of 16.6 kilograms or 55% over 1996. Among all kinds of meat products provided by my country's aquaculture industry, pork is the largest meat consumer product, accounting for about 63% of the meat consumed. Accord...
