Abstract
Insects could be a potential replacement of protein-rich ingredients in poultry diets. Among these insects, black soldier fly (BSF), Hermetia illucens, has a high content of protein and fat, which reinforces the potential of using it in poultry feed formulation and makes it one of the most promising insect species for commercial production. Protein content as well as amino acid profile in H. illucens larvae is comparable to those in many protein-rich feedstuffs such as fish meal and soybean meal. BSF can convert organic wastes into a precious source of nutrients, such as proteins, lipids, and chitin, which contribute to reducing the environmental burden and pollution potential arising from organic waste accumulation. This review emphasizes the significance of this insect as a “green” technology in the extremely variable recycling of organic waste and generates a sustainable protein source as well as the importance of its use as a substitute of protein-rich feedstuff in poultry feed manufacturing.
Highlights
Poultry is by far the largest livestock group
Increasing maggot meal concentration up to 100% fish meal replacement impaired the feed conversion ratio (FCR) without significant differences. These results indicate that the inclusion of the insect larvae meal at low concentration appears to be more suitable in poultry diets
During two-phase feeding systems (28–35 days and 0–35 days) compared to a soybean-based control diet [113]. This may have been due to the higher nutrient content of larvae meal diet compared to soybean meal, essential amino acids (29.5 vs. 18.3%, respectively), and due to the higher digestibility values of crude protein and amino acids in maggot compared to soybean meal [113]
