The aim of this work was to study the effect of different housing systems (wire-net cage vs pen; 0.15 m2 per rabbit) and gender (male vs female) on the growth performance and carcass traits of fattening rabbits. A total of 110 Hyplus rabbits (PS 19 × PS 39) of both sexes (1:1) were weaned at 36 days of age (on average 908±11 g). The rabbits were provided with a standard fattening diet.
