Objective: To study the effects of oromucosal detomidine gel administered sublingually to calves prior to disbudding, and to compare its efficacy with intravenously administered detomidine.
Study design: Randomised, prospective clinical study.
Animals: Twenty dairy calves aged 12.4 ± 4.4 days (mean ± SD), weight 50.5 ± 9.0 kg.
Methods: Detomidine at 80 μg kg-1 was administered to ten calves sublingually (GEL) and at 30 μg kg-1 to ten control calves intravenously (IV). Meloxicam (0.5 mg kg-1) and  local anaesthetic (lidocaine 3 mg kg-1) were administered before heat cauterization of horn buds. Heart rate (HR), body temperature and clinical sedation were monitored over  240 minutes. Blood was collected during the same period for drug concentration  analysis. Pharmacokinetic variables were calculated from the plasma detomidine  concentration-time data using non-compartmental methods.
 Results: The maximum plasma detomidine concentration after GEL was 2.1 ± 1.2 ng  mL-1 (mean ± SD) and the time of maximum concentration was 66.0 ± 36.9 minutes. The bioavailability of detomidine was approximately 34% with GEL. Similar sedation  scores were reached in both groups after administration of detomidine, but maximal sedation was reached earlier in the IV group (10 minutes) than in the GEL group (40 minutes). HR was lower after IV than GEL from 5 to 10 minutes after administration. All animals were adequately sedated, and we were able to administer local anaesthetic without resistance to all of the calves before disbudding.
Conclusions and clinical relevance: Oromucosally administered detomidine is an  effective sedative agent for calves prior to disbudding.
