The objective of this thesis was to develop a method for DNA based traceability in pork and to realise this method in the production system of the “Interessengemeinschaft für Zertifizierung” (IGZ) GbR. 14 microsatellite markers have been selected and genotyped in the given population. Characteristics of quality were determined for each marker. The theoretical feasibility of the traceability system was reviewed by a simulation procedure, which was developed in three steps: At first, the genotype of the sample was solely compared with the genotypes of all sows of the production system. By additional comparison with the genotypes of the potential fathers in the second scenario a larger number of sows could be excluded. The third scenario included additional information in order to reduce the number of markers and the expenses. Simulation of three scenarios showed that DNA based traceability is realisable in the production system of the IGZ GbR. Nevertheless, the number of micro satellite markers should be increased in order to guarantee a distinct identification. The DNA based traceability was established in the production system of the IGZ GbR in several steps. During the realisation three trial runs were conducted. The assignability of the DNA-based traceability method to a system containing a larger number of parents was analysed, the alternative use of SNPs as genetic markers was investigated and it was examined, if there could be an influence of the genotype on the litter size.
