Yes – across various animal groups. In piglets, Hermetia illucens-based products improved protein digestibility and gut health, leading to higher weight gains and more stable gut microbiota. Turkeys fed with Hermetia-based diets showed better feed conversion ratios and greater resistance to oxidative stress, suggesting improved liver function. In aquaculture, Hermetia-based feeds effectively replaced fishmeal – in studies on rainbow trout and tilapia, they boosted growth performance and resistance to infection. In companion animals, insect protein is used in diets for dogs with food allergies, and research shows it is well tolerated and does not cause digestive issues – even in sensitive animals.
