Nutritional composition,effect of four organic Side-Streams on black soldier fly larvae feeding

Black soldier fly (BSF) larvae, Hermetia illucens L. (Diptera: Stratiomyidae), can effectively convert the organic wastes into a nutrient-rich biomass and appropriate for animal feed, the composition of larve largely dependent on the composition and structure of the side stream which are used. The polyphage diet and the quality of the larvae's macronutrients (mainly lipids and proteins) make them suitable candidates for different applications such as organic side-streams management and using as protein sources in animal feed. In the present study, BSF larvae were reared on feed substrates composed of Mix of fruit and date pulp, Mix of fruit and olive pulp, mix of waste fruit and bread and waste fruit which is a readily available and cheap source of agriculture,s by product in Iran. The dry matter, crude fat, crude protein and ash of the BSF larvae fed each feed waste organic were quantified by chemical analyses. Larval weight, survival and feed conversion were also recorded. The results showed that the mixed of date and fruit pulp and the mixed of olive and fruit pulp are suitable diets for BSF rearing. Our findings may provide important supporting information to support the use of BSF larval meal as potential new source of nutrient- rich and supportable animal feed ingredients to substitute expensive and limited protein sources such as fishmeal and soya beanmeal.
