Effects of Meloxicam on Hematologic and Plasma Biochemical Analyte Values and Results of Histologic Examination of Kidney Biopsy Specimens of African Grey Parrots (Psittacus erithacus)

J Avian Med Surg. 2015 Mar;29(1):1-8. doi: 10.1647/2013-056.


In this study we evaluated the effects of meloxicam administered at 0.5 mg/kg IM q12h for 14 days on hematologic and plasma biochemical values and on kidney tissue in 11 healthy African grey parrots (Psittacus erithacus). Before treatment with meloxicam, blood samples were collected and renal biopsy samples were obtained from the cranial portion of the left kidney from each of the birds. On day 14 of treatment, a second blood sample and biopsy from the middle portion of the left kidney were obtained from each bird. All birds remained clinically normal throughout the study period. No significant differences were found between hematologic and plasma biochemical values before and after 14 days of treatment with meloxicam, except for a slight increase in median beta globulin and corresponding total globulin concentrations, and a slight decrease in median phosphorus concentration. Renal lesions were absent in 9 of 10 representative posttreatment biopsy samples. On the basis of these results, meloxicam administered at the dosage used in this study protocol does not appear to cause renal disease in African grey parrots.
