Genetic traceability refers specifically to methods associated with the identification of animals and their products through DNA characterization of individuals, breeds or species.For the purposes of breed traceability it is necessary to define the breeds group to analyze, and the most appropriate molecular marker set. Marker selection depends on gene frequencies distribution, genetic distance among breeds and presence of private alleles. In this study, we assessed six SNPs located in DGAT1, TG, LEP, GH, FABP4 and GnRHRgenes,as potential genetic markers to be included into a traceability panel for the identification of breed origin associated with the bovine beef trade. The genetic characterization of four of the mayor Chinese cattle populations, and the principal breeds raised in Argentina and/or in the whole world (five Bostaurus and two B. indicus) suggests that thesestudied SNP markers can be successfully used as a part of an effective traceability system for the identification of cattle breed origin in the context of the Chinese meat imports, and in particular in the Argentinean-Chinese beef trade.
