Súhrn: Traceability systems help guarantee that products bought from stores exactly correspond to the description on the label. Traceability maps the journey of the food, from the store, throughout processing, right back to the original livestock. DNA can be used as a natural barcode, as it carries unique genetic information and can be used to identify individual animals. Genetic variability of markers was analysed with the aim of confirmation of the available set of 13 microsa­tellites. With the addition of five polymorphic markers, the probability of finding two animals sharing the same profile was, on average, four in ten million for the entire dataset. In Slovakia in 2015, 65?126 red deers were recorded. Using only the five extra polymorphic markers, it was possible to obtain a reliable individual genetic traceability system.
