摘要

Hermetia illucens larvae, commonly known as black soldier fly maggots, have the potential to produce fatty acids and vitamin D. This study examines the effects of fatty acids and vitamin D on maggot growth performance, fatty acid and vitamin D deposition, and transfer efficiency. The larvae were raised on a basal substrate added with 6% chicken fat (T0), 6% palm oil (T1), 6% flaxseed oil (T2), and 6% flaxseed oil combined with 10,000 IU/kg of vitamin D (T3). A completely randomized design (CRD) was used, consisting of four treatments with four replicates each, with 100 maggots per replicate. The study measured growth performance, fatty acid profile, and the transfer efficiency of lauric acid (C12:0), linolenic acid (C18:3), and vitamin D. The results showed that fatty acid and vitamin D addition did not significantly affect larval biomass. However, the fatty acid source in the substrate significantly influenced the fatty acid profile, particularly mono-unsaturated fatty acids (MUFA) and poly-unsaturated fatty acids (PUFA) (p < 0.05). The transfer efficiency of C12:0 ranged from 5.06 to 6.48% of the nitrogen-free extract (NFE) in the substrate, with the highest effect observed in the chicken fat and flaxseed oil treatments. Additionally, the transfer efficiency of C18:3 significantly increased, ranging from 17.8 to 29.6% of the fatty acids (p < 0.05). Flaxseed oil or flaxseed oil combined with vitamin D had the greatest effect. The transfer efficiency of vitamin D was 3.12% higher than in treatments without vitamin D addition (p < 0.01). In conclusion, variations in fatty acids within the substrate influenced both the fatty acid profile and transfer efficiency, particularly for unsaturated fatty acids such as linoleic acid. Furthermore, adding vitamin D improved the transfer efficiency of fatty acids without impacting growth parameters and the fatty acid profile.
