The aim of this trial was to test the effect of differrent housing systems, organic and intensive, on productive characteristics of a rabbit local population of Tuscany characterized by slow growing. 84 rabbits of a local population were housed in colony cages under organic system (Group A) according to an official organism of certification which states the exclusive use of local strains; 72 rabbits of the same population (Group B) and 72 Hybrids (Group C) were housed in colony cages under conventional system. The rabbits were fed ad libitum with an organic diet. At the weight of 2400g but at different ages (local population:102 days; hybrids: 90 days) 30 animals of each group were slaugheterd. The local population showed the best productiva performances: Groups A and B had the lower mortality (Group A 12% and Group B 10% vs Group C 28%), the higher slugther live weight (Group B 2539g vs Group A 2433g vs Group C 2306g) and the higher weight gain (Group A 27g and Group B 28g vs Group C 25g). Group A and B carcasses had the higher dressing percentage (Group A 61% and Group B 61% vs Group C 58%) due to the lower full gastrointestinal tract (Group A 20% and Group B 19% vs Group C 22%) and the higher commercial carcass percentage (Group A 59% and Group B 59% vs Group C 57%). These results promote meat production obtained by slow growing rabbit population fed with organic diet, characterised cy low energy content and without any pharmacological supplementation

Abstract
The aim of this trial was to test the effect of differrent housing systems, organic and intensive, on productive characteristics of a rabbit local population of Tuscany characterized by slow growing. 84 rabbits of a local population were housed in colony cages under organic system (Group A) according to an official organism of certification which states the exclusive use of local strains; 72 rabbits of the same population (Group B) and 72 Hybrids (Group C) were housed in colony cages under conventional system. The rabbits were fed ad libitum with an organic diet. At the weight of 2400g but at different ages (local population:102 days; hybrids: 90 days) 30 animals of each group were slaugheterd. The local population showed the best productiva performances: Groups A and B had the lower mortality (Group A 12% and Group B 10% vs Group C 28%), the higher slugther live weight (Group B 2539g vs Group A 2433g vs Group C 2306g) and the higher weight gain (Group A 27g and Group B 28g vs Group C 25g). Group A and B carcasses had the higher dressing percentage (Group A 61% and Group B 61% vs Group C 58%) due to the lower full gastrointestinal tract (Group A 20% and Group B 19% vs Group C 22%) and the higher commercial carcass percentage (Group A 59% and Group B 59% vs Group C 57%).
