Christophe BOSTVIRONNOIS President of French Branch of WPSA Dear Colleagues, On behalf of the French Branch of WPSA, the Organizing Committee, the Scientific Committee, and the Working Group no.9 “Poultry Welfare and Management” of the European Branch of the WPSA, I would like to extend to all of you a very warm welcome to the X European Symposium on Poultry Welfare in Ploufragan, Brittany, France. I would like this scientific symposium to achieve 3 responsibilities: Support, Benchmark and Simplicity. Support First. During this meeting, you will have the opportunity to discuss, to share and to debate the latest scientific findings, the researches and the areas of development in the field of poultry welfare. Your role is crucial to support the poultry industry to keep birds welfare at a higher level and in line with the requirement of the consumer demand AND within an acceptable level to maintain the production. Benchmark then. Of course, competitiveness of the production, costs of production is in the agenda of the poultry production globally. The interesting point is that Welfare topics used to be very European driven in the mid 90’ and early 2000’. Now the topic is well spread in the different continents and regions. It makes our responsibility, in Europe, even more important. The world is looking to us and what we are discovering, deciding is considered as a global benchmark by the international community. Make it Simple. Welfare is far more complicated that to have broilers outdoors on a green grass. It covers topics as production methods, behaviors, health, nutrition, genetics and of course interactions between all of them. It makes the topic complex to handle. This is passionate but at the same time, we have to have in mind that we need to put our decisions, conclusions into reality in an actionable way. To do this, we need to be pragmatic and simple. How can we transfer these very complex topics into something easy to handle and to transform? Once again, we are very pleased to welcome a very high number of participants coming from many countries and continents. Definitely this is the healthy signal of a growing production, researches and education. Our responsibility is bigger than us. This is to feed the world in a safe, abundant, affordable and sustainable way. Introduction Valentina FERRANTE – Chairwoman of the Working Group n° 9 The WPSA European Federation Working Group 9 (WG9) on Poultry Welfare and Management, together with the WPSA French branch, organised this Xth European Symposium on Poultry Welfare held in Ploufragan, Brittany, France June 19-22th 2017. A memory stick (and a book on request) provide the main record of its proceedings. Agreement to form WG9 was taken during the WPSA European Poultry Conference in London in 1972. Its inaugural meeting held in Dortmund, Germany during 1973 was attended by 7 members, including me, from 6 countries (Lindgren, N.O. (1973). WPSJ 30 (2): 143- 145). Membership and geographical coverage have greatly increased during recent years so that WG9 currently has 33 members from 21 countries. The first event organised by WG9 was a symposium on bird welfare during the 1976 WPSA European Poultry Conference in Malta. The first European Symposium on Poultry Welfare organised by WG9 was held in Koge, Denmark in 1981. Quadrennial symposia have followed at different venues, the last one was the 9th Symposium in Uppsala, Sweeden. Apart from scientists, the participants to WG9 Symposia generally come from policy making authorities, funding bodies, the industry and welfare organizations. Hence, these symposia provide excellent opportunities to receive and discuss reports on the latest poultry behaviour, welfare and management research and practice, and for important informal exchanges of information as well as local professional poultry tours. Past symposia have been characterised by high quality scientific invited and submitted papers and posters. I am pleased to thank the scientific committee for the excellent program and several members of WG9 for their hard work in rigorous review of the presented abstracts to ensure that this Xth Symposium in Ploufragan was no exception. The number and standard of contributions was very high once more, making this event truly worthwhile!
