The Effect of Fentazine-induced Sedation in Farmed Elk (Cervus canadensis)

사육 엘크의 Fentazine 진정효과

This study was performed to assess clinical signs, sedative effect and clinicschemical profile of a mixture of fentanyl-azapemne-xylazine(Fentazine$^{(R)}$) in formed elk Twelve male elk(Cervus canadensis) were immobilized with Fentazine, and blood samples were taken of femoral venous blood. Samples were analyzed in the conditions of 10- and 30-minute after administration of the drug. Heart rates, respiratory rates, and body temperatures were in normal ranges during Fentazine anesthesia. After iqiection of Fentazine, most of elk were recumbency and did not respond to needle prick In young adult(3.5.4.5 years old) elk a high dose(>3.0 ml/head) of Fentazine does not result in more sedation, but it does prolong the duration of sedative effect. Fentazine induced sufficient analgesia far velvet antler removal and hoof trimming in elk Salivation, urination, intermittent apnea and mild bloat were observed in elk Globulin, alanine aminotransferase, aspartate aminotransferase, blood urea nitrogen, calcium, magnesium and phosphorus values were in normal ranges for at least 30 minutes after Fentazine administration. Total protein, albumins cortisol and prothrombin values were slightly increased during sedation(p<0.05). It was concluded that Fentazine is effective analgesic drug being useful for velvet antler removal and hoof trimming.
