Seventy fives of New Zealand White (NZW) rabbits weaned at 4-weeks of age and weigh (545±3.4g) were used in the present study to investigate the effect of stocking density on their growth performance, carcass traits and some blood parameters. Rabbits were randomly assigned to three stocking densities: 12, 20 and 28 rabbits/m2 (Represented 3, 5 and 7 rabbits/cage of 2500 cm2; respectively). Rabbits housed at 12 rabbits/m had the lowest feed conversion ratio (P=0.053), the highest average daily feed intake (P=0.001), final live body weight (P=0.003) and average daily weight gain (P=0.001). At 13-week of age, concentration of hemoglobin (g dL-1), packed cell volume (%), the mean corpuscular volume (fl) and lymphocytes % were 1 significantly (P=0.001) high for rabbits stocked at 12 rabbits/m2 . Rabbits kept at 28 rabbits/m revealed the highest platelet count and white blood cell count as compared to other groups. The mean corpuscular hemoglobin (pg cell-1), Mean corpuscular hemoglobin concentration (g dL-1) and red blood cell count were not affected by stocking density. The stocking density had a significant effect on hot carcass weight, dressing out percentage, liver weight and kidney in addition to head percentage. While the other traits were not affected by the stocking density. Rabbits stocked at 12 rabbits/m2 had the highest hot carcass weight (1418 g), dressing out percentage (66.47%), liver weight (70.65 g) and the lowest kidney and head percentages (0.51 and 6.38%, respectively). It could be concluded that increasing stocking density up to (20 rabbits/m2 ) induce stressful condition in term of increasing WBCs and platelet counts and some disturbance in performance and carcass traits of NZW rabbits.
