Abstract

The invention discloses a combination of SNP markers for the traceability identification of beef cattle individuals and meat products and its application. The SNP marker combination of the present invention contains 32 highly polymorphic sites distributed on 29 autosomes. The minimum allele frequencies of the combined loci were all greater than 0.35. Experiments have proved that this combination can be successfully applied to the individual identification and meat traceability of beef cattle other than yak breeds on the market, which is conducive to the realization of the whole chain traceability of breeding-slaughter-sales, and truly guarantees the safety of food.

Description

technical field

[0001] The invention belongs to the field of individual identification and traceability detection, and in particular relates to a combination of SNP markers for traceability identification of beef cattle individuals and meat products and its application. Background technique

[0002] Food traceability technology is considered to be the most reliable means to ensure food safety and protect the legitimate rights and interests of consumers. At present, the traditional electronic ear tag technology (radio frequency identification system) has problems such as easy loss, easy tampering of traceability information, and difficulty in traceability from meat products to livestock breeding. The gene traceability technology represented by SSR (Simple sequence repeat) and SNP (Single nucleotide polymorphism) has the advantages of uniqueness, inalterability, and hard-to-lose, and is gradually becoming a powerful supplement to the electronic ear tag traceability system.
