Large file listing illnesses, including nutritional and infectious conditions, with a review of the cause, treatment and prevention.

The most common preventable disease that we see at our practice is hypovitaminosis A, or vitamin A deficiency, with or without accompanying secondary infections. Pet birds that eat only seeds (especially sunflower seeds and peanuts) are most prone to this problem because an all-seed diet is low in vitamin A.

The most common clinical signs of PDD include depression, weight loss (with or without decreased appetite), constant or intermittent regurgitation, and/or passage of undigested seeds in the feces indicating a malabsorptive or maldigestive disorder. Central nervous system signs associated with PDD, which may occur in addition to, or independent of, gastrointestinal signs, may include ataxia, abnormal head movements, seizures and proprioceptive or motor deficits.
