SNP molecular marker related to intramuscular fat content characters of pigs and application of SNP molecular marker

Abstract

The invention belongs to the technical field of preparation of molecular markers of livestock and in particular relates to location of an SNP molecular marker related to the intramuscular fat content of pigs and application of the SNP molecular marker. The SNP molecular marker is obtained from whole genome correlation analysis, and the nucleotide sequence of the SNP molecular marker is as shown in the sequence table SEQ ID NO:1 and figure 2. The marker can be used in the correlation detection of the intramuscular fat content characters of the pigs.

Description

technical field [0001] The invention belongs to the technical field of livestock molecular marker preparation, and specifically relates to a SNP molecular marker related to pig intramuscular fat content traits and its application. Background technique [0002] In pig breeding work, breeders have always regarded increasing lean meat percentage and reducing backfat thickness as the main breeding goals. Although this breeding method has achieved remarkable results, its genetic selection eventually leads to a decrease in intramuscular fat content, which in turn leads to a decline in pork quality. With the continuous improvement of consumers' requirements for meat quality, genetic research to improve pork quality has become a research hotspot in animal husbandry. [0003] Muscle fat is divided into intermuscular fat and intramuscular fat (IMF). Intermuscular fat is located around muscle tissue and is composed of fat cells. Intramuscular fat includes lipids inside muscle cells ...
