title: A case of nutritional secondary hyperparathyroidism in a Siberian tiger cub.
abstract: A three-month-old female Siberian tiger cub with hindlimb ataxia was referred to the veterinary teaching hospital of Konkuk University. The patient was fed only beef without supplementation of calcium and vitamins after weaning. The tiger was presented with ataxia and back pain on digital palpation. In addition, abnormal gait, reluctance to move, and depressed withdrawal reflex were noted at the neurological examination. The overall osteodystrophic change of the lumbosacral vertebrae was observed on the lateral and ventrodorsal view of radiographic examination. And also PTH level was increased in hormonal assay when compared to that of cat reference range. Based on the results of examinations, nutritional secondary hyperparathyroidism was diagnosed. Clinical signs of this patient were improved after administration of vitamin D and calcium. This case demonstrates that nutritional hyperparathyroidism could be occurred in wild animals raised on a meat diet containing imbalanced calcium and phosphate.
