Development and Application of a New Insect-Based Complete Diet for Insectivorous Mammals

Commercial complete diet options for insectivores are very limited and most are an extruded diet. The extrusion process requires a high level of carbohydrates, which is not appropriate for animals that consume insects. Insects do not contain high levels of carbohydrates, they are mainly fat and protein. Chitin is an important component of insects, found in the exoskeleton, it acts...

Practical Investigation of Cricket Dust Supplements Commonly Used to Enhance Diets Provided to Insectivore Species under Human Care

Amphibians and reptiles commonly managed under human care are commonly fed farmed feeder crickets (Acheta domesticus) that are deficient in calcium. Calcium deficiency can lead to the development of nutritional metabolic bone disease in animals consuming the crickets; therefore, feeder crickets are commonly supplemented with calcium by either dusting the crickets’ exoskeleton or by providing crickets with a calcium enriched...

Evaluation of zoological hoofstock supplements

Traditionally, U.S. zoos have fed two types of forage to exotic hoofstock species, primarily a legume (usually alfalfa, Medicago sativa) or grass hay(s). In addition to the forage, a grain supplement is added primarily as a carrier for vitamins and minerals, but also for supplemental energy. This has been the diet of choice for most ruminant and non-ruminant species with...

Determination of Vitamin E status and supplementation for the Nyala (Tragelaphus angasi)

High incidence of white muscle disease in captive nyala has lead to speculation that they have high vitamin E requirements. Maintenance of nyala is often achieved through high vitamin E supplementation. Injectable vitamin E has been administered monthly (750 IU/injection) at Denver Zoological Gardens for years as an effective method of preventing vitamin E deficiency related deaths, yet, was evaluated...
