The experimental
treatments did not alter hepatic enzymes activity including AST and ALT (P > 0.05). The
results showed that serum testosterone concentration was increased in groups 3 and 4
(P < 0.05). In addition, the serum concentration of T4 (tetraiodothyronie) was higher in
groups 3 and 4 (P < 0.05). However, the T3 (triiodothyronine) concentration was not
influenced by experimental treatments (P > 0.05).
