Summary Three combinations of injectable anaesthetic agents were compared in nine adult mules. The combinations were xylazine/ketamine (X/K), xylazine/butorphanol/ketamine (X/B/K), and xylazine/tiletamine‐zolazepam (X/T). Measured variables were heart rate, respiratory rate, systolic blood pressure, arterial blood pH, PCO 2 and PO 2 , recumbency time and number of attempts to stand. Quality of induction and recovery, muscle relaxation and response to stimulus were evaluated subjectively. Recumbency time was significantly (P<0.05) longer with X/B/K and X/T than with X/K. Mules required significantly more attempts to stand under the influence of X/T than X/K or X/B/K. No statistically significant (P<0.05) differences in heart rate, respiratory rate, blood pressure or arterial pH, PCO 2 and PO 2 were detected between groups.
