Except for two relative new members, all states have implemented Directive 2008/120/EC in their legislation. A limited number of countries formulated stricter or additional demands to the EU legislation. Floor area, floor design and group housing of sows are the main themes with additional demands. Governments of more than half the member states fund research on
pig welfare issues. The main themes are floor design, group housing, environmental enrichment, castration and farrowing pens. The authors cautiously conclude that group housing of sows is not challenged but implemented, that surgical castration may be an issue in future legislation, and that members states are interested but hesitant to change the rules on farrowing systems and tail docking of piglets.
