This research is step 2 of the Dutch Dalfsen Declaration. The welfare check (on-farm risk analysis) has been developed with which pig farmers can determine the risks for bite behavior on their farm. In a network with motivated pig farmers, experience has been gained with the welfare check, writing a Plan of Action to address risks and keeping pigs with long tails. The network shows that with the welfare check pig farmers have a tool to analyze causes of tail bite problems. On 1/3 of the farms in the network it was possible to deliver some pens with 90% intact tails. However, larger investments are needed in a number of companies to eliminate the risks of bite behaviour. For these and some other reasons set out in the report, it is not recommended that all pigfarms stop docking without a doubt. The report describes the results with conclusions and recommendations including recommendations for the roll-out in practice.
