One way to address food safety and feed production is through the rearing of insects that exhibit a small ecological footprint, high growth and reproduction rates, high levels of protein, fat and minerals. Forty growing guinea pigs were fed to evaluate the effects of isonitrogenated and isoenergetic diets in which different proportions of soybean meal (0%, 16%, 32% and 50%) were replaced with Hermetia illucens meal, evaluating feed consumption/day (g/day), total feed intake (g), final body weight (g), total weight gain (g) and feed conversion index. The trial was conducted in a repeated measures Analysis of Variance with Greennhouse-Geisser correction. Crude Protein in Hermetia illucens larva meal was 42.16 ± 3.67% (dry matter), replacing soybean meal did not show statistically significant difference between daily weight gain and body weight. The 32% replacement presented a higher daily...

BACKGROUND AND OBJECTIVES: In the meat industry, inefficient management of organic waste exists, therefore the study aims to evaluate different bovine and poultry organic residues as food substrates during larval development of the black soldier fly, such as a sustainable alternative to obtain high protein meal. METHODS: The research evaluates the use of organic waste from cattle and poultry slaughterhouses, as food substrate for black soldier fly larvae, including raw beef blood T1, raw beef viscera T2, cooked beef blood T3, cooked beef viscera T4, raw chicken viscera T6 and cooked chicken viscera T7; further, as a control measure balanced feed (7 treatments and 5 replicates). Larvae were fed for 5 days and processed to make meal by drying and grinding; evaluating mortality, weight, size, proximal chemical composition, and apparent digestibility to determine the most viable substrate, a...
