<b> </b>The Food and Agriculture Organization’s previsions show that by 2050 the world’s population will reach 9.6 billion people, and the request for a high value protein source will increase as well. Poultry can guarantee high value protein for humans, even in the poorest regions of the world. Hence, efficient poultry production is needed, matching with sustainable development. The residual meal from cardoon seed oil (used for biodiesel and biodegradable bioplastic production) is suitable for animal feeding due to its protein content. The aim of this preliminary study was to test for a possible use of cardoon meal as a protein source in a poultry diet during the finishing period. Forty-five Kabir chickens were divided into three groups and fed three diets in which soybean meal (control) was partially (16%) or completely replaced with cardoon meal as a protein source (treated groups). In vivo performances, animal welfare, dressing out and meat color were evaluated. No statistical differences in feed efficiency, dressing out, nor in meat quality were found among groups. Moreover, birds that were fed cardoon meal showed lower perivisceral fat. Therefore, cardoon meal could be considered as an alternative for soybean meal in the finishing period in poultry feeding.
