Depending on their age and size, snakes may be fed multiple times in one week or every 2 to 4 weeks. If nutritional support is truly needed, then assisted feeding is indicated in the hospitalized snake. Tube feeding is commonly performed in critically ill snakes after fluid therapy and supplemental heat is provided.
Unfortunately the sedentary lifestyle of the companion bird makes obesity one of the most common forms of malnutrition seen in clinical practice. Pet birds are fed too much food or they are fed diets rich in sources of fat, such as sunflower seeds .
Turtles and tortoises display a variety of dietary strategies ranging from the complete herbivory seen in many tortoises to the strict carnivory displayed in aquatic species like the snapping turtle. There are also many chelonians, such as the Eastern box turtle, that may be considered opportunistic omnivores. This review article, critiqued by reptile nutritionist, Susan Donoghue, discusses clinical concerns related to feeding the hospitalized turtle or tortoise. Topics covered range from recognizing true anorexia to food items to avoid. Practical technical concerns related to nutritional support such as tube feeding and daily caloric requirements are also discussed.
Fasting may be expected in lizards during certain times of the year. Many gravid females eat less or go off feed entirely due to the large number of eggs filling the coelom. Some species also fast for weeks or months as an adaptation to excess heat or cold, drought, or lack of food. This dormancy in reptiles is called…
Exotic animal veterinarians are well aware of the differences between energy expenditure in small and large species. Larger animals use more energy overall, however when energy expenditure is divided by body weight (kcal/kg/day), large animals use relatively less energy than small animals
In humans and small animals, the combination of feeding reduced calorie foods, providing regular exercise and using behavior modification to change eating patterns bring about the best chance of achieving and maintaining weight loss (Toll 2010). A key nutritional factor for weight loss and the prevention of weight gain is to feed calorie-restricted diets.
