The objective was to assess the analgesic effects of 2 doses of meloxicam on the degree of postoperative orthopedic pain in pigeons. Twenty-one domestic pigeons were used. In each bird, a standardized osteotomy of 1 femur was performed and the fracture was immobilized with an intramedullary pin. Birds were randomly allocated to receive saline solution (0.9% NaCl) (control) or meloxicam (0.5 mg/kg [low dose] or 2 mg/kg [high dose]). The first treatment was administered intramuscularly after surgery was completed. Subsequent treatments were administered by mouth every 12 hours for 9 days. Degree of postoperative pain was assessed for the first 4 days after surgery by use of 3 methods: an electronic perch for assessment of weight-bearing load differential of the pelvic limbs, 4 pain scales, and analysis of video-recorded partial ethograms for bird activity and posture. No significant differences were observed between the control group and the low-dose meloxicam group in any tested variable. The high-dose meloxicam group had a greater degree of weight bearing on the affected limb from the second to the fourth postoperative day as well as lower pain scores for at least the first 2 postoperative days, compared with the other groups. Return to presurgical behavior was achieved faster in pigeons that received high-dose meloxicam than in the other groups. No adverse effects were observed. Administration of meloxicam at 0.5 mg/kg appeared ineffective in minimizing postoperative orthopedic pain in pigeons, but the 2 mg/kg dose provided quantifiable analgesia that appeared safe in this species in experimental conditions.
