Evaluation criteria for including feed materials in Annex II C and dietary supplements in Annex II D of the EC-Regulation 2092/91ASundrumauthorSPadelauthorOrganic livestock farming is intended to contribute to the equilibrium of agricultural production systems; establish and maintaining an interdependence between soils, plants and animals; is land-related ruling out landless productions, and should support the development of a sustainable agriculture. The criteria for the evaluation of non-organic and organic feed inputs should be consistent with these principles of organic livestock production. This report provides an overview of issues to be considered with regard to the inclusion of criteria for non-organic and external feed materials in the further development of the EC-Regulation 2092/91 on organic food. The various implications of a criteria based approach are discussed in relation to the main objectives and principles in organic production. A system approach is recommended to provide a tool for balancing the divergent and ambivalent issues in relation to the inclusion of non-organic and external feed material on the different levels relevant in organic production.
