Live performance, carcass traits and hind leg bone characteristics of crossbred rabbits of both sexes (Sx) of two sire breeds (SB): Vienna Blue – (VB) and Burgundy Fawn – (BF) born with different parity orders (P: 1, 2, ≥3), reared organically and slaughtered in the spring and summer, when they reached 2.8 kg, were evaluated. The slaughter age of VB crossbreds increased between P1 and P2 (P<0.05). During the summer, the rabbits exhibited a higher slaughter age (P<0.01), reference carcass yield (P<0.01), and hind leg meat-to-bone ratio (P<0.05). The P2 crossbreeds exhibited the lowest incidence of scapular fat (P<0.05). The weights of the full gastrointestinal tract and skin were 2.4% higher and 1.5% lower in females, respectively (P<0.01), and head proportion was higher in males (P<0.05). Females exhibited a longer femur and thicker tibia than did the males (P<0.05). The results confirmed the slow growth rate of the crossbreds evaluated, which may represent an interesting genetic resource for organic production of rabbits.
