Douw Grobler : The Hilti worked well! The HH and BT mixtures worked very well and Louis Greeff's fine tuning worked its wonders!! I cannot get over it that it works so well. On an animal like this, we used 1.25 mg opioid mix (half M99 and half Thianil) plus 6 mg medetomidine plus 16 mg Stresnil (azaperone) I did 3 animals today and none had any issues with respiration, circulation or muscle rigidity.
