4. The working group carried out an extensive consultation exercise, obtained oral and written evidence from experts in outdoor pig production and carefully examined scientific data. Visits were made to a number of outdoor pig farms, both large and small; a seminar was held with invited experts from industry and research bodies; and oral and written evidence was taken from animal protection societies.
5. Those who gave evidence and information are listed at Appendix B and we would like to thank all who participated. In particular, the Council is indebted to Mr Tony Walker of ADAS who attended the working group meetings and visits and provided expert advice; and Dr Jane Guise of Cambac JMA Research who also attended many of our meetings.
