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...

Gastritis in the Short-Beaked Echidna (Tachyglossus aculeatus): Parallels with Ruminal Acidosis in Herbivores and Implications for the Understanding of Echidna Digestive Physiology

Short-beaked echidnas (Tachyglossus aculeatus) are endemic to Australia and south-eastern New Guinea (Indonesia and Papua New Guinea). In mainland Australia they feed primarily on termites. Echidnas have a single chambered stomach which is entirely lined with squamous (non-glandular) cells, and is histologically analogous to the rumen. The short-beaked echidna stomach has historically been understood to function as a grinding or...

Short-Beaked Echidnas (Tachyglossus aculeatus): An Insectivorous Herbivore

Short-beaked echidnas are considered myrmecophages, carnivores that specialize in eating termites and ants. Dogs and cats have been used as the carnivore models to develop their artificial diets. Echidnas appear to do well on artificial diets, often living 50+ years in captivity. A recent review of necropsies of echidnas at Taronga Zoo revealed pathology in captive echidnas that may have...

Investigation of a new diet formula for captive short-beaked echidnas (Tachyglossus aculeatus)

Short beaked echidnas (Tachyglossus aculeatus) are myrmecophages, ant and termite specialists, and replicating their diet in captivity is problematic. Captive diets often incorporate raw meat, eggs and cat food mixed together with water and vitamin and mineral supplements. These diets have presented a number of health problems, such as cystitis, gut impaction, obesity and diarrhea. This study aimed to assess...
