TE (%) in 11 horses at the withers or nostrils. TE (%) in 11 horses at the withers or nostrils treated with saline, acepromazine or acepromazine + buprenorphine TE % = 100 × ([TT ‒ T0]/[Tc ‒ T0]). TT is the thermal threshold temperature, T0 is the skin temperature and Tc is the thermal cut-out temperature. 0: baseline measurement; Ti: time point of injection (15 min); *: significant (p < 0.05) difference in thermal threshold compared to baseline A: TE (%) at the nostril B: TE (%) at the withers.
