Popis: | 1. 1. Plasma testosterone and luteinizing hormone (LH) concentrations in immobilized or yarded rusa stags (Cervus rusa timorensis) were investigated over a two-year period. 2. 2. Testosterone concentrations showed a minor elevation in autumn (May) and reached maximal levels in late winter-early spring (August) coinciding with the rut. 3. 3. Luteinizing hormone in plasma was only detectable from January to May. 4. 4. Maximal responsiveness of the pituitary-gonadal axis to LH-RH stimulation was recorded in August. 5. 5. The combination of Fentaz® (fentanylcitrate and azaperone) and Rompun® (xylazine hydrochloride) for immobilizing deer influences hypothalamic function. |
