Chemical composition and nutrient digestibility of insect meal for broiler

Abstract

Abstract To determine the chemical composition and digestibility of insect meal for poultry made from the larvae of Tenebrio molitor (TL) and nymphs of Gryllus assimilis (GAN) a total excreta collection test was carried out, substituting 20% of the reference diet with each type of meal. The meals presented 6074 and 5975 kcal/Kg of gross energy, with 49.34% and 52.66% protein for TL and GAN respectively. The most nutrient digestibility was less than 65%, except for energy and ether-extract digestibility in the meal from Tenebrio molitor larvae, which were over 70%. The meals under analysis can be used as a source of nutrients in poultry diets.
