In a preliminary study the reduced urine excretion of cortisol (F) and 6β-hydroxycortisol (6βOH-F) in cattle treated per os with low doses of dexamethasone (DEX) was proved. To assess the potential of these parameters as indirect markers of illegal use of corticosteroids, the concentration of F and of 6βOH-F were evaluated (by RIA and by ELISA, respectively) in urine samples collected from 40 beef cattle at the slaughterhouse. Four animals were considered to be suspected for corticosteroid treatments as F concentration in urine was below the cut-off value of 1 ng/mL.

Abstract
In a preliminary study the reduced urine excretion of cortisol (F) and 6β-hydroxycortisol (6βOH-F) in cattle treated per os with low doses of dexamethasone (DEX) was proved. To assess the potential of these parameters as indirect markers of illegal use of corticosteroids, the concentration of F and of 6βOH-F were evaluated (by RIA and by ELISA, respectively) in urine samples collected from 40 beef cattle at the slaughterhouse. Four animals were considered to be suspected for corticosteroid treatments as F concentration in urine was below the cut-off value of 1 ng/mL.
