From weaning until slaughter (27 to 75 d of age), 384 rabbits were kept into 72 individual cages (72 rabbits), 48 bicellular cages (2 rabbits/cage; 96 rabbits) and 24 colony cages (9 rabbits/cage; 216 rabbits). Rabbits in individual cages showed higher final weight (P=0.10), growth rate (P=0.07) and feed intake (P<0.01) compared to rabbits kept into bicellular and colony cages, but similar conversion index. Dressing percentage and carcass quality were similar apart from muscle to bone ratio of hind leg (P<0.05), higher in rabbits reared in individual cages compared to colony. On biceps femoris muscle, the b* index increased (P<0.001) from rabbits of individual to those of bicellular and colony cages. We can conclude that the rabbits in individual cages showed growth performance somewhat higher compared to those kept in bicellular and colony cages while slaughter results and meat quality did not differ substantially among the three housing systems.

Abstract

From weaning until slaughter (27 to 75 d of age), 384 rabbits were kept into 72 individual cages (72 rabbits), 48 bicellular cages (2 rabbits/cage; 96 rabbits) and 24 colony cages (9 rabbits/cage; 216 rabbits). Rabbits in individual cages showed higher final weight (P=0.10), growth rate (P=0.07) and feed intake (P<0.01) compared to rabbits kept into bicellular and colony cages, but similar conversion index. Dressing percentage and carcass quality were similar apart from muscle to bone ratio of hind leg (P<0.05), higher in rabbits reared in individual cages compared to colony. On biceps femoris muscle, the b* index increased (P<0.001) from rabbits of individual to those of bicellular and colony cages. We can conclude that the rabbits in individual cages showed growth performance somewhat higher compared to those kept in bicellular and colony cages while slaughter results and meat quality did not differ substantially among the three housing systems.
