The use of insects as a sustainable protein-rich feed ingredient in
pig and poultry diets is technically feasible. Insects can turn lowgrade
biowaste into proteins.
• The amino acid profile of yellow mealworm, common housefly,
and black soldier fly is close to the profile of soybean meal with
methionine or methionine + cystine, which are generally the most
limiting essential amino acids for growing pigs and broilers. Arginine
can also become a limiting essential amino acid for broilers
fed housefly pupae and mealworm.
• Additional research is recommended on digestibility of (processed)
insects, inclusion levels in poultry and pig diets, functional
properties, safety when using biowaste as a rearing substrate,
extraction of nutrients, shelf life, and use of left-over substrates
and residue products of insects.
• To compete with conventional protein sources and become an
interesting link in the animal feed chain to fulfil the globally increasing
demand for protein, cost price of insect production and
processing should be further reduced.
