Ryan van Deventer : 31 August 2022 Can anybody recommend a combo for a feral horse? Henry Labuschagne: I use medetomidine 2mg and Azaperone 10mg per 100kg in 1st dart. Once showing effect give 2nd dart with M99 @ 1mg per 100kg. If you give all in one dart they show effect from etorphine first and go bananas . Good luck. Ryan van Deventer: Just some feedback on the horse darting. Went on Henry's recommendation: 8mg medetomidine and 40 mg Azaperone. Waited 15 minutes and followed up with 4mg Etorphine and 100mg Ketamine. Went down well. Easy to manage and geld. Loaded and reversed with 25mg Naltrexone IM and 12mg Atipamezole IV. Up and standing calm within 3 minutes. 👍 Ben Potgieter: 9 September 2022 Anybody castrated donkeys and be so kind as to supply a anaesthetic dosage? Luis Amaral, [09 Sep 2022 at 15:27:29]: Yes, semi-wild donkeys had to dart with 2 mg etorphine 4mg medetomidine and 20 mg azaperone. Some tremors observed but worked ok. Midazolam should help with tremors but it was quick done and reversed. Tamed donkey 0.5 Domosedan and 1 ml butorphanol iv. Some books advocate etorphine, detomidine and butorphanol combination. Asiatic wild ass in Mongolia they used successfully 4 etorphine, 10 detomidine and 10 butorphanol. Without butorphanol they run km. Przewalski wild horses: 2.5 to 3 etorphine 10 detomidine and 10 butorphanol induction 5-10 minutes.
