Anaesthetic dosage regimen is different in birds when compared to animals because of its flying behavior and due to change in its anatomy and physiology. A total of 12 broiler birds were selected and divided into two groups. Group I (6) birds were given xylazine-ketamine combination (xylazine @ 3mg/kg b.wt., I/M + 5 minute later ketamine @ 20 mg/kg b.wt., I/M) and for group II (6) dexmedetomidine-ketamine combination (dexmedetomidine @ 5µg/ kg b.wt., I/M + 5 minute later ketamine @ 20 mg/kg b.wt., I/M) were administered. The physiological parameters viz., heart rate, respiratory rate and rectal temperature were observed within the normal range in both the groups. Anaesthetic parameters viz., onset of anaesthesia, duration of anaesthesia and recovery periods was quicker (pā¤0.05) in group II than group I respectively. Other anaesthetic parameters viz., sternal and lateral recumbency, closure of eyes, beak touching the ground and locomotion in recovered birds were earlier (pā¤0.05) in group II than group I respectively. The complication of anaesthesia like gasping was seen in group I only. Whereas,defecation was observed in both the groups. Other complications like limb stretched backwards, rigidity of legs, paws curled and loosened neck were observed in group II only.
