Abstract: Blood samples of three kinds of cattle under the same feed management conditions in both winter and summer were randomly blooded.The antioxidation indexes of three kinds of cattle including T-SOD,Cu/Zn-SOD,GSH-Px,T-AOC and MDA were detected by using visible spectrophotometer,and serum trace elements including Se,Cu,Zn and Mn were determined by using atomic absorption and fluorescence spectrophotometry.The results showed that the T-SOD,Cu/Zn-SOD,T-AOC,Cu,Zn,Mn and Se of New Zealand imported Jersey cattle and Holstein were significantly higher than local Holstein in winter（P〈0.05）,except for GSH-Px.There were no significant difference in the T-SOD,Cu/Zn-SOD,GSH-Px,Mn and Se of New Zealand imported Jersey cattle,Holstein and local Holstein in summer（P〉0.05）.The T-AOC of New Zealand imported Jersey cattle was significantly higher than local Holstein（P〈0.05）.It is concluded that New Zealand Jersey cattle imported in summer has higher adaptability.
