Meloxicam, a commonly used NSAID, has wide variation in pharmacokinetics between different avian species. The present study hypothesized that meloxicam dosage regimens were similar within, but differ between, groups of avian species with similar feeding habits, habitats, or migratory behaviors. Utilizing the international Zoological Information Management System (ZIMS), drug usage extracts were compiled for meloxicam across eleven major orders of birds. The orders were selected based on their prevalence in zoological collections, wildlife rehabilitation centers, the pet trade, and production environments. Each species with a record available in drug usage extracts was classified into broad categories of main habitat, diet, and migratory status. Significant patterns associated with habitat, diet, or migratory status were not identified statistically. An inverse relationship was identified statistically between the practitioner mg/kg dose and body weight in kg in birds that weigh approximately 20 kg or greater. This study includes practitioner-reported summary data of current doses used in the veterinary field to treat many different avian species. Adverse effects of meloxicam were recorded in <5% of individuals evaluated at the species level in this study.
