The EC directive regarding minimum standards for the protection of pigs (2001/93/EG) states that: "Pigs must have permanent access to a suffi cient quantity of material to enable proper investigation and manipulation activities, such as straw, hay, wood, sawdust, mushroom compost, peat or a mixture of such, which does not compromise the health of the animals". Implementation of this directive into practise requires farmers and policy makers to decide whether materials such as a chain, a plastic ball, a piece of hardwood or artifi cial plastic tails meet the objective of allowing proper investigation and manipulation activities. In order to support the decision-making process we conducted a literature review (number of references > 40), elicited expert opinion (n>50) and started to systematically log and analyse the relationships between materials, material properties and welfare indicators. The preliminary results confi rm that providing a metal chain is certainly not suffi cient (86% agreement) while the provision of loose, unchopped straw generates considerable credits (`straw` received 75% agreement). More importantly, however, the evidence is building up that it is possible to formalise the `translation` from available scientifi c results into an index or other support-tool, which policy makers and farmers can use to make the required practical decisions. Critical evaluation from the international scientifi c community is recognised as a critical success-factor for the proposed methodology and its implementation to support decision-making concerning environmental enrichment for pigs and other animal welfare problems.
