Insects do not replace cells once they mature. In order for prey insects to adjust their nutritional content, it is most effective to keep them on a diet that enriches them for at least several days, preferably until they have molted at least once. To increase calcium content, quality food such as ground gamebird laying pellets can be augmented with calcium carbonate, found in powdered oyster shell or powdered eggshells. On the advice of an excellent herp vet, I found that many lizards will self-feed on small chips of eggshell left in their cages. Collared and Leopard lizards do this, and it may be worth considering for other species as well. The main thing is to have prey insects feed for an extended period on adequately nutritional food so they have time to incorporate nutrients into their tissues. I believe this is preferable to simple gut-loading.


Have a nice weekend God Bless Our Troops!
