The experiment was conducted to study the effects of dietary copper levels on the production performance and serum indices of weanling to 2-month-old growing meat rabbits. One hundred New Zealand weanling rabbits were randomly divided into 5 groups with 20 replicates each and 1 rabbit in each replicate. Rabbits in the control group were fed basal diet and those in test groups were fed basal diet supplemented with 20, 40, 80 and 160 mg/kg copper (CuSO4·5H2O), respectively. The trial lasted for 28 days, including preset period for 7 days and test period for 21 days. The results showed that, the copper levels in diet had significant effect on the average daily gain (P=0.002 4), but no significant effect on the feed/gain ratio and average daily intake (P>0.05); the copper levels in diet had no significant effect on the activities of cuprozincsuperoxide dismutase and ceruloplasmin in serum (P>0.05); the dietary copper levels could significantly increase the contents of total protein and globulin in serum（P=0.040 3, P=0.043 6）, while the albumin, albumin/globulin ratio, urea nitrogen and total cholesterol in serum were not significantly affected (P>0.05 ); the dietary copper levels had significant effect on insulin (P=0.005 9) and the growth hormone (P=0.024 8), while no significant effect on the insulinlike growth factor-Ⅰ(P>0.05). In conclusion, the appropriate supplementation of copper in diet of weanling to 2-month-old New Zealand rabbits was 40-80 mg/kg (the actual content of copper in diet was 50～90 mg/kg)
