Husbandry-related conditions are very common in reptiles. This case-based teaching module explores a condition frequently encountered by reptile veterinary health professionals. This teaching module is approved for 1 hour of continuing credit for veterinarians and veterinary technicians by the American Association of Veterinary State Boards (AAVSB) Registry of Approved Continuing Education (RACE).
Husbandry-related conditions are very common in reptiles, and nutritional secondary hyperparathyroidism is frequently recognized in clinical practice. The discussion portion of this Case Challenge reviews pathogenesis, history, examination findings, and diagnostic test results with radiography, and clinical pathology. Key points of case management are explored, including correction of husbandry and dietary factors, management of hypocalcemia, as well as stabilization and supportive care. Prognosis and prevention are also discussed.
The most widespread mineral in the body, calcium is required for normal metabolism and bone mineralization.
Calcium homeostasis is under the control of calcitonin, which is produced by the ultimobranchial gland, vitamin D, and parathyroid hormone. In laying hens, most dietary calcium is used for egg production. Rising estrogen levels promote increased intake of calcium supplements like cuttlefish bone and calcium-rich foods, however the quantity of calcium ingested daily is insufficient for the massive deposition of calcium required for eggshell calcification.
In 1998, an expert committee met to discuss the nutritional needs of companion birds. The purpose of the meeting was to discuss and develop nutrient profiles for companion birds, focusing on profiles for formulated feed.
The expert panel developed maintenance guidelines for two broad groups of birds: psittacines and passerines (regardless of size or genus). These conservative, generalized guidelines are extrapolated from the National Research Council requirements for poultry and…
