Sažetak

This research was conducted to determine the correlation between selenium, copper, zinc, manganese, and triiodothyronine (T3), thyroxine (T4), free triiodothyronine (fT3) and free thyroxine (fT4). Blood samples were collected from 56 clinically healthy, non-pregnant ewes in 3 different times over 45 days. Serum T4, T3, fT4 and fT3 were measured by the RIA method and selenium, copper, zinc and manganese by atomic absorption spectrophotometer. Comparing the values of the trace elements and thyroid hormones from 3 samplings showed that there was no significant difference in any of the above mentioned parameters. There were significant positive correlations between fT3 and zinc (P<0.05, r = 0.41), fT3 and manganese (P<0.05, r = 0.49) and copper and T3 (P<0.01, r = 0.27). There was a significant negative correlation between manganese and T3 (P<0.01, r = -0.30). There were no significant correlations between other biochemical parameters.
