The experiment was performed on 24 ewes divided into 4 groups. Experimental sheep were injected parenterally either with a sodium selenite and Emulsigen mixture or sodium selenite or Emulsigen. The injection of sodium selenite and Emusigen mixture, and Emulsigen alone substantially increased serum copper and magnesium concentrations. Moreover, a marked decrease in creatine kinase activity was found in all experimental groups as compared to that in the controls. No significant alterations in iron, zinc, calcium, and phosphorus concentrations and the enzyme's activities were noted.
