An exploratory analysis of the suitability of diets fed to a flightless insectivore, the North Island brown kiwi (Apteryx mantelli), in New Zealand
Abstract The ingredients and the macro- and micro-nutrient contents of diets that are fed to captive kiwi at seven New Zealand holding facilities were subject to analysis. The nutrient compositions were compared across facilities and with an estimate of the nutrient composition of the diets of wild kiwi based on the intake of various dietary […]
Estimate of chitin in raw whole insects
Abstract 10.1002/zoo.20123.abs Insects contain significant amounts of fiber as measured by crude fiber, acid detergent fiber (ADF) or neutral detergent fiber (NDF). It has always been assumed that the fiber in insects represents chitin based on the structural similarity between cellulose and chitin and the fact that the ADF fraction from insects contains nitrogen. In […]
Complete nutrient composition of commercially raised invertebrates used as food for insectivores
Abstract 10.1002/zoo.10031.abs A variety of invertebrates are commonly fed to insectivorous animals by both zoos and hobbyists, but information as to the nutrient composition of most commercially raised species is limited. Adult house crickets, house cricket nymphs (Acheta domesticus), superworms (Zophobas morio larvae), giant mealworm larvae, mealworm larvae and adult mealworms (Tenebrio molitor), waxworm larvae […]
Complete Nutrient Content of Four Species of Feeder Insects
A variety of insects are commonly fed to captive insectivores but detailed nutritional analyses are only available for the most commonly fed species. Soldier fly larvae, Turkestan cockroach nymphs, tebo worms, and adult house flies were analyzed for moisture, protein, fat, ash, acid detergent fiber, neutral detergent fiber, minerals, amino acids, fatty acids, vitamins, and […]
Complete nutrient content of four species of commercially available feeder insects fed enhanced diets during growth
Commercially raised feeder insects used to feed captive insectivores are a good source of many nutrients but are deficient in several key nutrients. Current methods used to supplement insects include dusting and gut-loading. Here, we report on the nutrient composition of four species of commercially raised feeder insects fed a special diet to enhance their […]
