One of the most common signs of zinc toxicity is feather picking. Other symptoms include loss of appetite, increased or decreased water consumption, and central nervous system disorders. We can run a blood test to determine if your bird has elevated zinc levels. We have also noticed elevated amylase levels in many birds that have high levels of zinc. Amylase is a pancreatic enzyme.
Zinc targets the pancreas and appears to cause damage resulting in elevated amylase levels.
Amylase is included in our routine blood screens. Other causes of elevated amylase levels are dietary problems, infection, neoplasia, and degenerative conditions. Treatment for zinc toxicity involves removal of the offending source and chelation with either injectable or oral therapy depending on the severity of the signs. Most birds recover well when treated promptly. They require a very specific diet, strict temperature control, special ultraviolet-B lighting and proper humidity.
