Therefore, this review aimed to provide a comprehensive understanding and recent reports on the role of insect meal in poultry feed aimed at improving health condition and gut status in poultry production. The gut microbiota living in an animal’s gastrointestinal tract can be modulated through the feeding of prebiotic or probiotic compounds which have effects on the animal’s humoral immunity, hence improving the nutrient utilization and thus improving growth performance and the overall health condition of the animal.

A well-developed gastrointestinal tract will have a proper balanced proportion between the beneficial and harmful microbes therefore, this balance will promote nutrient utilization and stimulate the development of immune system. The structure and functionality of digestive system and gastrointestinal microbiota composition play a crucial role in the development of the gastrointestinal tract and gut morphology.
