An 8-month old female veiled chameleon presents for a 3-day duration of anorexia and lethargy. Use history, physical examination findings, laboratory results and survey radiographs to solve this case challenge.
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.
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.
Part of LafeberVet’s Rabbit Basics Teaching Module, the Rabbit Anatomy Basics slideshow is a 22-minute recording designed to impart a basic understanding of rabbit anatomy for the veterinary technician and veterinary nurse. This slideshow may also be of use as a basic learning aid for veterinary medical students and as a basic refresher for the clinician.
The following chart shows the calcium content in 1 cup of selected foods. Select treats for adult rabbits and rodents that are high in fiber, low in calcium, and low in carbohydrates and sugars.
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.
Urolithiasis is characterized by single or multiple calculi throughout the urinary tract or by the presence of sandy material within the bladder and urethra. Uroliths are fortunately more of a historical disease in the ferret, while calculi are still an important problem in rabbits and rodents.
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.
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…
Although hematology and biochemistry are an important part of the clinical picture in the avian patient, this bloodwork remains just ‘part of the picture’. All too often, when a clinician is unfamiliar with a species, the reaction is often to rely on laboratory results to hang a diagnosis upon. Although we have all been guilty of this, such an approach is inappropriate. For each sick bird, the following diagnostic tools should be applied: complete history, visual examination of the bird and its environment, physical examination, clinical pathology sample collection (blood, feces, swabs, aspirates, etc.), and radiography.
White blood cells are similar to mammalian lines, except that mammalian neutrophils are replaced with heterophils and mammalian platelets are replaced with thromobocytes. There are significant variations in normal differentials among avian species, in particular the total white cell count and…
Rabbits are prey species. Their survival depends on the ability to be alert and respond quickly, and they possess acute senses of smell and hearing. Approach rabbits in a calm, quiet manner. Stressed or critically ill rabbits may not tolerate prolonged handling. Evaluation and treatment may need to proceed slowly in stages.
Abnormal urine in the rabbit typically appears white and chalky or pigmented. These changes can be related to the unique metabolism of calcium in the rabbit. Rabbits absorb nearly all calcium ingested; therefore blood levels vary substantially with the calcium content of the diet…
Common reproductive conditions of the reptile include prolapse of the cloaca, oviduct or copulatory organ, yolk coelomitis, dystocia or egg binding, as well as follicular stasis. This review article on twelve key facts explores clinically relevant anatomy and physiology and appropriate husbandry as well as key points of urgent care and general principles of case management.
The sugar glider is a small, nocturnal marsupial native to New Guinea and Australia. Sugar gliders are omnivores that eat arthropods and plant products, such as eucalyptus phloem sap, manna, honeydew, nectar, and pollen in the wild. Although there is little medical information available on sugar gliders in captivity, nutritional secondary hyperparathyroidism or metabolic bone disease is recognized as a common problem in this species.
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.
Small mammals, such as rabbits and rodents, are stoic by nature and have evolved to mask their illness to avoid predation. This behavior can create a false sense of security in owners and a clinical challenge for veterinarians. In some cases, an animal that appears clinically normal may in fact have a terminal illness. Use hematology and biochemistry analysis to characterize the true physiological status of these species and aid in disease diagnosis.
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…
