Effects of oilseed meals on black soldier fly larvae: growth, nutritional composition, gut microorganisms, and chemical property

Summary: | Oilseed meals are limited in feed due to antinutritional factors. Black soldier fly larvae (BSFL; Hermetia illucens) represent a promising and sustainable protein source for converting diverse substrates. This study evaluated BSFL reared on flaxseed meal (FM), tiger nut meal (TNM), and Zanthoxylum bungeanum seed meal (ZBSM), assessing growth, nutrition, gut microbiota, and antioxidant capacity. Results showed that 20 % oilseed meal supplementation (FM20, TNM20, ZBSM20) significantly enhanced larval growth and biomass yield versus control (CK). Nutritionally, the above three groups increased the crude protein and crude fat by 9.24 %–14.35 % and 18.6–21.95 % compared with CK. Fatty acid analysis showed a 50 % elevation in C12:0 in FM20 and TNM20 groups, while ZBSM20 showed a 14 % increase in unsaturated fatty acids compared to CK. Gut microbiota analysis indicated a substantial enrichment of Firmicutes—reaching 80.24 %, 60.58 %, and 99.26 % in FM20, TNM20, and ZBSM20, respectively—far exceeding the CK group (44.32 %). This finding clearly demonstrates that substrate composition plays a pivotal role in shaping gut microbiota structure. Furthermore, peptide hydrolysates derived from oilseed meal-reared BSFL displayed superior antioxidant capacity over CK, suggesting that oilseed meals enhance the bioactive properties of BSFL-derived products. Our results demonstrate that BSFL can efficiently convert oil crop processing waste into nutrient-dense insect protein, offering a sustainable solution for animal feed industries. |
