Insect Meal as a Source of Protein in Animal Diet

The increasing, worldwide demand for fishmeal due to the development and expansion of the poultry industry raises the market price of fishmeal. Insects can be a perfect alternative as a source of protein in poultry diets due to the high percentage of protein (55-70%) they contain, along with a high-quality profile of amino acids. In addition, insects greatly improve chicken meat quality and decrease the cost of production. However, the use of insects as a source of protein in animal diets is still prohibited due to different feed safety and quality laws. Insect protein is only allowed in fish or shellfish feed in Europe; however, the purified fat extracted from larvae is allowed to be used in animal diets. In conclusion, insects have proven to be a sustainable source of protein, are of an attractive quantity and quality, and have acceptable nutritive properties. The use of insects as a potential protein-rich feed ingredient in diets is practical and creates new perspectives in mono-gastric animal feeding.
