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.
Dr. Susan Orosz presented this live, interactive webinar event on the clinical perspectives of avian nutrition. How can veterinary health professionals best address the nutritional needs of the companion bird in the exam room?
This 1-hour, R.A.C.E.-approved webinar recording is designed to impart a basic understanding of avian nutrition for the veterinary health professional as well as students in these fields. Viewing of this recorded is strongly recommended before viewing the recording of the live webinar event Clinical Avian Nutrition for Veterinary Health Professionals by Susan Orosz, PhD, DVM, DABVP (Avian Practice), DECZM.
Calcium is the most abundant mineral in the body, and the majority of total body calcium is found within bones and teeth. Most mammals make only one or two sets of teeth in a lifetime, however rabbit teeth continually grow throughout their lifetime. This continual tooth eruption plays an important role in the rabbit’s long-term calcium needs.
There are a number of potential nutritional problems that can promote renal disease. Excess dietary protein, excess dietary calcium, hypovitaminosis A, or hypervitaminosis D may lead to nephritis or other degenerative renal changes…
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.
Created with a focus on the bird, LafeberVet’s Nutrition Glossary is an extensive list of vocabulary terms. Listed terms range from nutrients like vitamins and minerals, nutritional strategies ranging from frugivore to fungivore, and related anatomy or physiologic terms like crop and coprodeum, and even nutrition-related diseases like goiter and gout.
Little is known about the nutritional requirements of companion bird species. Dietary recommendations for pet birds are extrapolated from domestic poultry nutritional requirements; however these parameters are generally calculated to minimize cost while maximizing meat and egg production.
The types of foodstuffs consumed in the wild are often used to classify the nutritional requirements for groups of animals. Usually birds within the Order Psittaciformes are considered to consume plant-based foodstuffs and are classified as florivores. Subdivisions within this category include granivores (budgies and cockatiels), frugivores (many of the macaws), and nectarivores (lorikeets and lories). Yet these artificial lines are sometimes too simplistic, as many psittacine birds cross over a category to consume a larger variety of foodstuffs…
