Gut-Loading Diet Evaluation for Crickets (Acheta domesticus), Mealworms (Tenebrio molitor), and Superworms (Zophobas morio) for the Purposes of Optimizing Institutional Protocols

For captive insectivorous birds, reptiles, and amphibians, gut-loading has become an essential part of a balanced diet when feeding commercial feeder insects. The captive bred crickets, mealworms, and superworms being fed have inadequate Ca and vitamin A to meet the nutritional needs of these animals. The trials conducted for this study were to determine which gut-loading diet would be the...

Carotenoid Gut-Loading of Crickets and Mealworms

The lack of diversity of invertebrate prey items available to feed captive animals limits available nutrients, requiring manipulation of the diet fed to these prey items prior to offering to other animals. Of late, much of the gut-loading research and recommendations focused on correcting the Ca:P imbalance inherent to the insects available through commercial production. More recently, attention has shifted...

Evaluation of nutrient composition of common invertebrate feeders fed different supplemental diets

While the complete nutrient composition of invertebrates commonly fed to insectivorous animals has been studied, research evaluating the differences among supplemental diets marketed to improve their overall nutrient composition is limited. Previous studies have focused on calcium intake in crickets, and to a lesser extent in mealworms, but diets for superworms have not been evaluated. This study evaluated the proximate...

Calcium gut loading of mealworms (Tenebrio molitor) and the benefit of gel water over apple slices for maximum calcium gut loading

The importance of gut loading insects with calcium is a critical component of an insectivorous animal’s diet. The insect used in this study for calcium supplementation was the regular mealworm (Tenebrio molitor). The standard operating procedure for most gut loading protocols includes feeding high-water produce items (i.e., apples, leafy green vegetables, etc.) in conjunction with a high calcium insect supplement....

A zoo-wide evaluation into the current feeder insect supplementation program at the Brookfield Zoo

Commercially raised insects are an important food source for captive animals. For those animals that are purely insectivorous, the nutrient concentrations of the food source are vitally important for the health and welfare of the animal, particularly the Ca to P ratio. In the summer of 2002, a zoo-wide evaluation of the current methods of insect supplementation was conducted at...

Effects of a high calcium diet on gut loading in varying ages of crickets (Acheta domestica) and mealworms (Tenebrio molitor)

Insects are a poor source of calcium. Consequently, it is a common practice for zoos to supplement them in order to provide a nutritionally balanced diet to many species. Current methods of supplementation include dusting and gut-loading. The experiment was conducted in order to determine the effect of a high calcium diet on gut loading in varying ages of crickets...
