Evaluation of Worms as a Source of Protein in Poultry

Continuous improvement of the genetic potential through breeding studies in poultry has led to an increase in the nutrient density of the feed rations given to these animals. In poultry farming, approximately 70% to 75% of the operating costs constitute feeding costs, of which about 15% are animal proteins. The protein requirement of poultry is provided by feed stuff rations and usually by soy bean meal or fish meal. Limited production opportunities and price increases have led to the need to use alternative feed additives that can be substituted for these products. Research conducted to date suggests that worms, rich in essential amino acids and a high digestible protein source can be used as substitutes. As a source of alternative protein, worms are consumed by their poultry in their natural habitat, while intensive and extensive studies are needed to be used as a sustainable feed additive. In this review, research on the usability of worms as an alternative protein source in poultry diets has been compiled and evaluated.
