Faced with growing societal expectations in terms of animal welfare, it seems necessary to improve the living and slaughter conditions of farm animals. This improvement calls for an increased involvement and mobilization of all actors, farmers and professionals in daily contact with animals, veterinarians, veterinary public health inspection services, the food industry, scientists and animal protection associations. It requires the production of increasingly precise scientific knowledge and the transfer of this knowledge, the improvement of the dialogue between these actors as well as a better training of professionals and better information of civil society.
