| Abstract: | Rex rabbits were selected to analyze the changes of serum malondialdehyde（MDA）,total superoxide dismutase（T-SOD） and total antioxidant capacity（T-AOC） by using colorimetric method during heat stress with different intensity（25℃,30 ℃,35 ℃ and 40 ℃）and different time（0.5,1.5,2,2.5,4 and 6 hour）.The results showed as follows： Compared with the control group（25 ℃）,the MDA contents in serum decreased slightly（P0.05） after heat stress with 30 ℃ and it was significantly lower at 35 ℃ and 40 ℃（P0.01）.The SOD activity in serum of Rex Rabbit was in rising trend and T-AOC was in declining trend.The SOD activity and T-AOC-size in every heat stress group had very significant differences comparing with the control group.During heat stress with different time,the MDA contents in serum raised and reached the peak with 4 hour（P0.01）and then decreased.There were no differences between heat stress with 6 hour and 0.5 hour.The SOD activity and T-AOC-size in serum of Rex rabbit were in fluctuation.Compared with heat stress 0.5 hour,the SOD activity and T-AOC-size in every heat stress group were very significantly increased（P0.01）.The T-AOC-size in serum of Rex rabbit was significantly increased after heat stress with 1 hour（P0.05）and very significantly decreased after heat stress with 1.5 hour,2 hour（P0.01）.There were not differences between other groups for T-AOC-contents in serum of Rex Rabbit. |
