Capture and Anaesthesia of the Mongolian Wild Ass (\u3ci\u3eE. hemionus\u3c/i\u3e)
Science-based conservation efforts in general and wide-ranging equid conservation specifically, often require capture and subsequent handling of the subject animal. Safe and animal-welfare appropriate wild equid capture and anesthesia is a complex operation necessitating a multitude of skills that require appropriate veterinary training. In order to develop management plans for the Mongolian wild ass (Equus hemionus), which range over vast areas the use of radiotelemetry, is an essential tool. Radio-telemetry allows the researchers to better understand the habitat requirements and to delineate the areas of potential wildlife-human conflicts. To date we have successfully captured 16 wild ass in the Gobi regions of Mongolia. The agent of choice for wild ass capture and anesthesia is the potent opiate ethorphine in combination with specific opiate antagonists that allow for the complete reversal of the anesthetic effects. The recommended dosage for healthy, adult wild ass procedures anesthesia is a combination of 4.4 mg ethorphine, 10 mg buthorphanol and 10 mg detomidine. Anesthesia was reversed with the opioid antagonist-agonist diprenorphine or a combination of 200 mg naltrexone and the alpha2-antagonist 20 mg atipamezole. All wild asses were standing and alert approximately two minutes following administration of the antagonists
The Danger of Having All Your Eggs in One Basket—Winter Crash of the Re-Introduced Przewalski's Horses in the Mongolian Gobi
Large mammals re-introduced into harsh and unpredictable environments are vulnerable to stochastic effects, particularly in times of global climate change. The Mongolian Gobi is home to several rare large ungulates such as re-introduced Przewalski's horses (Equus ferus przewalskii) and Asiatic wild asses (Equus hemionus), but also to a millennium-old semi-nomadic livestock herding culture

3.0 mg ethorphine, 10 mg of the alpha2-agonist detomidine and 10 mg of the opioid agonist-antagonist
butorphanol. In Przewalski’s horses ethorphine is reversed with the opioid antagonist naltrexone (200
mg). In khulan procedures anaesthesia was induced with a combination of 4.4 mg Ethorphine, 10 mg
Detomidine and 10 mg Buthorphanol. Anaesthesia was reversed with the opioid antagonist-agonist di-
prenorphine or a combination of 200 mg naltrexone and the alpha2-antagonist 20 mg atipamezole. All
