Coren is a second-tier cooperative, which means it is a ‘cooperative of cooperatives’. The producers of the different activities (poultry farming, pig rearing, cattle raising, rabbit breeding or egg laying) associate in cooperatives which integrate in Coren’s cooperative structure. That is why Coren is a second-tier cooperative. Such structure allows for farmers to directly involve in management. Hence, they are the most interested parties in achieving the highest quality in every phase of the production process as well as in a socially responsible management, which are the keys for success of the ‘Coren model’.
