The purpose of the study was to assess the isoflurane sparing effect of butorphanol and buprenorphine during low flow isoflurane anaesthesia in cattle. The study was conducted in 30 cattle divided into three equal groups. Acepromazine premedication at the dose rate of 0.04 mg/kg i.v. was employed in the animals of all the groups. Butorphanol 0.02 mg/kg i.v. was administered five minutes prior to acepromazine in group II and buprenorphine 0.006 mg/kg i.v. fifteen minutes prior to acepromazine in group III.. In all the groups, guaifenesin 50 mg/kg and ketamine 4 mg/kg were administered intravenously to induce anaesthesia, which was maintained with isoflurane employing rebreathing circle. The end–tidal isoflurane concentration was significantly lower in the groups that received butorphanol or buprenorphine compared to the control group indicating that inclusion of opioids in the anaesthetic protocol had a significant isoflurane sparing effect.
