Black soldier fly (Hermetia illucens) has long been known to be an important insect for its significant capability of organic matter bioconversion. It can provide not only a high level of nutritional supplementation, but also has the potential reduction of feed cost. The purpose of this study was to determine its nutrient composition as animal feeds in general, where samples of local BSF larvae that grew on local palm oil wastes were chosen as substrate with 17.4% crude protein content for approximately 3 weeks at 30 ? 2 ?C and 65 ? 5% relative humidity of natural condition. BSFL were killed by hot air oven drying and grinding where the mean percentage of the nutrient values of BSFL obtained were: crude protein 36%, crude fibre 15%, crude ash 18%, crude fat 28%, and dry matter 90%. From the feed safety aspect, heavy metals were determined with safe mean concentrations of Hg (0.03), Cd (0.6), As (0.2), Cr (3.5), and Pb (2.0) in ppm (2-5% RSD), respectively. There were no significant differences (p > 0.05) observed after eight-month storage at room temperature for protein, but (35%) reduction in fat and (20%) in fibre contents, screening of aflatoxin contaminations also showed to be below permissible level. Thus, the nutritive values of BSFL obtained in this study has shown a promising result and is comparable to other waste streams as substrate produced for animal feeds.
