The food crises of the last years have resulted in the development of vertical integrated quality assurance systems in the North European and Central European countries. These quality assurance systems require the whole value added chain, from feed to food retailing industry, complying with prescribed guidelines for the preservation of feed and food safety. Within the scope of the work a comparison of the vertical integrated quality assurance systems for pig fattening from Germany (QS), Denmark (DQG), the Netherlands (IKB), Great Britain (AFS) and Austria (AMA-Gütesiegel) was drawn with the help of the content analysis. With the help of selected criteria the system guidelines were examined from that point of view to be able to finally formulate recommendations to improve the Austrian quality assurance system for pig fattening. The results show that the levels of the various quality assurance systems have similarities, especially regarding the formulation of objectives and the testing system. Differences in the inclusion of the added value steps can be identified, because not every system includes all steps of the value chain. The Austrian quality assurance system for pig fattening has deficiencies and loopholes in several categories. The guidelines must be further developed concerning the demand for a crisis management system, animal husbandry and the involvement of veterinarians in greater detail. Moreover, the transport guidelines of goods along the value added chain hardly given and in the agricultural production guidelines in the feeding area no HACCP-system is required. Contrary to expectations, the Austrian quality assurance system of pig fattening can be improved in any areas. As a guideline serves, for example, the German QS-system for pig fattening, because it shows much more detailed directives.
