Technical Abstract: DNA marker technology represents a promising means for determining the genetic identity and parentage of an animal. DNA-based identification (ID) technologies differ from physical labeling methods (such as branding, tagging, and electronic implants) because DNA remains an integral and identifiable component of animal products long after they are separated from the carcass. DNA may be readily extracted and analyzed from samples of fresh, frozen, or cooked animal products. Thus, DNA-based ID technologies provide a "gold-standard" for auditing the fidelity of physical labels. Rapid traceability is critical for controlling animal disease, monitoring imports/exports, and is a requirement of some trading partners. This presentation will highlight the changes taking place in bovine SNP marker technology and provide three recent examples where SNP markers were used to solve practical problems of animal identification, parentage testing, and traceback.
