Eugenio Gaudio, Liesel L Laubscher, Leith C R Meyer, Louwrens C Hoffman, Jacobus P Raath, Silke Pfitzer,

Chemical immobilisation is essential for veterinarians to perform medical procedures in wild African ungulates. Potent opioids combined with neuroleptic drugs are most often used for this purpose. The present study aimed at comparing the quality of immobilisation and effects on physiological variables between a high (high etorphine-azaperone [HE]: 0.09 mg ... Read more >>
