Application of Microsatellite Markers in Pig Individual Identified and Pork Traceability

Abstract:

DNA traceability technology is based on DNA sequence different between individuals for individual identification and trace-back technology. Genetic diversity of 24 microsatellite markers were examined in the test groups(11 species, 192 individuals). 11 microsatellite markers were screened for pork traceability by heterozygosity and polymorphism information content. The further slaughterhouse traceability experiment was carried out and the results show that 11 microsatellite markers could distinguish 100 individuals. 10 collected tissue samples showed the same genotypes and belonged to No. 43 individual. This study has shown that microsatellite markers could be used for individual identification and pork traceability.
