Abstract

Hypervitaminosis D was diagnosed in a giant anteater (Myromecophaga tridactyla) and a large hairy armadillo (Chaetophractus villosus) being fed a commercial insectivore diet. Clinical findings included weight loss, reduced appetite, vomiting, and suspected abdominal discomfort. Hypercalcemia (3.68 and 2.04 mmol/L total and ionized calcium, respectively) was detected in the anteater, and plasma 25(OH)D levels were measured and found to be 808.7 and 379.4 nmol/L for the anteater and armadillo, respectively. Dietary change resulted in a reduction of 25(OH)D levels in both animals and resolution of hypercalcemia in the giant anteater. Dietary analysis of the commercial insectivore food revealed levels of vitamin D3 higher than the data-sheet values. This case report demonstrates that hypervitaminosis D in Xenarthra can be associated with significant clinical signs.
