Insect-enhanced diets of Periplaneta americana (L.), in separate combinations with Zea mays L. and starter mash/finisher, were fed to 4-week-old birds, Gallus gallus domesticus L., over a period of 13 weeks to identify alternative and relatively cheaper sources of protein for poultry birds. Within the first 3 weeks of feeding, the body weight of the birds was not significantly (P . 0.05) different from each other, whereas a significant (P ¼ 0.009) trend arose at week 8. This preliminary study shows that insect-enhanced meals could be used as an alternative feed within the formative stage of development of G. domesticus.
