ANALYSIS AND EVALUATION OF NUTRITIONAL CONTENT IN BLACK SOLDIER FLY PUPA (Hermetia illucens) FOR SUPPLEMENTARY APPLICATION IN ANIMAL FEED

Abstract

This study aimed to analyze and evaluate the nutritional composition of black soldier fly larvae (Hermetia illucens) at different developmental stages and to determine optimal rearing conditions for biomass and nutrient accumulation. The results showed that substrate pH significantly affected larval survival and biomass. Survival rates from larva to prepupa were highest at pH 6.0 - 8.0 (98.44 - 99.44%) and markedly lower at pH 2.0, 4.0, 10.0. Larval biomass was also higher under neutral to slightly alkaline conditions. Proximate analysis indicated that larval moisture content reached 77.95% and ash content was 8.86%. Crude protein content at 4, 14 and 28 days of age was 44.7%, 45.0% and 48.6%, respectively, while lipid content was 17.4%, 15.4% and 21.5%. These results demonstrate that black soldier fly larvae and prepupae are nutrient-rich resources with high potential as alternative protein and lipid sources for animal feed, partially replacing conventional feed ingredients.
