Superoxide dismutase (SOD) is an cytoplasmatic enzyme with antioxidant activity. Relationship among plasma concentrations of microelement as Zn and Cu and the erythrocyte SOD activity was investigated in man, bovine, rat and camels. The results of these researches showed different correlations among parameters taken in account. The aim of this work was to investigate the relationship between plasma Zn and Cu levels and erythrocyte SOD activity in buffaloes. A total of 204 blood samples were collected bimonthly from 34 female buffaloes raised in 4 different farms located in the Frosinone province (Italy) during a year period. The levels of parameters were similar than bovine (14,46 ± 3,29 μmol/l; 10,78 ± 7,46 μmol/l; 1433,7 ± 95,6 U/g Hb for Zn, Cu and SOD activity respectively) and have showed a similar trend during the productive periods with a minimum during the dry period. A negative correlation (r:-0,47; P<0,001) was found between Zn plasmatic levels and erythrocyte SOD activity. The result suggest that SOD activity could be different than bovine and to be caused by a genetic enzyme constitution.

Abstract
Superoxide dismutase (SOD) is an cytoplasmatic enzyme with antioxidant activity. Relationship among plasma concentrations of microelement as Zn and Cu and the erythrocyte SOD activity was investigated in man, bovine, rat and camels. The results of these researches showed different correlations among parameters taken in account. The aim of this work was to investigate the relationship between plasma Zn and Cu levels and erythrocyte SOD activity in buffaloes. A total of 204 blood samples were collected bimonthly from 34 female buffaloes raised in 4 different farms located in the Frosinone province (Italy) during a year period. The levels of parameters were similar than bovine (14,46 ± 3,29 μmol/l; 10,78 ± 7,46 μmol/l; 1433,7 ± 95,6 U/g Hb for Zn, Cu and SOD activity respectively) and have showed a similar trend during the productive periods with a minimum during the dry period. A negative correlation (r:-0,47; P<0,001) was found between Zn plasmatic levels and erythrocyte SOD activity. The result suggest that SOD activity could be different than bovine and to be caused by a genetic enzyme constitution.
