Amino Acid Content in Black Soldier Fly (Hermetia illucens) Oil in the Larval, Prepupal and Pupal Phases as a Feed Additive in Broiler

/in /by

The global livestock sector is facing mounting pressure to adopt sustainable and efficient feed alternatives that can meet the growing demand for animal protein. Among the emerging options, Hermetia illucens (Black Soldier Fly, BSF) oil presents a promising candidate due to its bioactive compound richness and capacity to upcycle organic waste into nutrient-dense biomass. This study investigates the essential and non-essential amino acid composition of BSF oil extracted from larvae (8 days), prepupae (14 days), and pupae (28 days) stages and evaluates its potential as a feed additive in broiler production. High-Performance Liquid Chromatography (HPLC) revealed significant variations across developmental phases, with larval oil exhibiting the highest lysine (4,467.56 mg/100g) and glutamic acid (7,564.45 mg/100g), while pupal oil was enriched in leucine (5,670.76 mg/100g) and tryptophan (4,356.79 mg/100g). The dynamic amino acid profile supports the inclusion of BSF oil as a stage-specific supplement in poultry feed, offering both nutritional and economic advantages. Findings from this study contribute to the growing body of knowledge on insect-based feed ingredients and provide critical insight for formulating phase-targeted broiler diets with optimized functional performance. However, essential amino acids such as leucine, lysine, and tryptophan remained stable or even increased. Among all stages, larval oil exhibited the richest amino acid composition, suggesting its suitability for use in high-performance starter feeds for broilers.

The Addition of Lauric Acid from DPKFA (Distilled Palm Kernel Fatty Acid) as A Feed Additive on The Physiological Responses of Broiler

The aim of the research is to examine the effect of adding additive products to feed on the physiological responses of broilers during 1 (one) rearing period including rectal temperature, shank temperature, comb temperature, respiratory frequency and heart rate frequency. The research was conducted from September 21 to October 26, 2024 in Mr. Soleh’s Farm. Kidal Village, Tumpang District, Malang Regency, East Java. The material used in this study was non-sexing DOC (Day Old Chick) strain Lohmann from PT Japfa Comfeed Tbk. A total of 300 broilers with a body weight diversity coefficient of less than 10% were reared for 35 days. This study used 6 treatment groups, each consisting of 5 replicates including T0 (Basal feed as control treatment), T1 (Basal feed + zinc bacitracin 0.1% as positive control treatment), T2 (Basal feed + 0.05% feed additive product), T3 (Basal feed + 0.10% feed additive product), T4 (Basal feed + 0.15% feed additive product) and T5 (Basal feed + 0.20% feed additive product). The data obtained were analyzed using analysis of variance (ANOVA) and continued with Duncan’s Multiple Range Test (DMRT) if there was a significant effect. The results showed that the addition of DPKFA-based feed additive products with high lauric acid content in the feed did not significantly affect the physiological response of broilers (P>0.05). The provision of additives with the highest concentration helps to optimize the physiological response of broilers so that this product can be recommended as a substitute for the role of AGP to support the performance of broiler production and health.
