The Potency of Black Soldier Larvae (Hermetia illucens L.) as a Source of Protein for Livestock Feed

Abstract

Black Soldier fly larvae is an insect capable to convert organic waste into body biomass. The purpose of this research was to determine the productivity, mass balance of the consumption process, and content of protein and fat of prepupa which has a potency as a livestock feed. This research used 6-day-old larvae, they were fed with cassava skin that has been smoothed with a variety of feeding doses: 12.5; 25; 50; 100; and 200 (mg / larvae / day) with ratio of feed and water 2: 1. The results showed that the feeding of 200 mg / larva / day produced the best larval growth with biomass productivity of 1.54 mg / day, residue yielded of 67.1 mg / day. The organic waste was convertion into larvae biomass. In this study, approximately consumption process scale is feed successfully converted to biomass 2.77%, metabolism 6.98%, and 90.24% residue. Protein content is 25.7%. It can be concluded that the larvae are able to convert organic waste into high protein biomass and potentially being used as a livestock feed. This research acts a model to predict mass balance of substrates for feed. The benefit of this research is the science approach used in this study that can be used as a reference by researchers and the community to determine the biomass production of an organism.

Effect of Feeding Rate on Growth Performance and Waste Reduction Efficiency of Black Soldier Fly Larvae (Diptera: Stratiomyidae)

“…It was believed that yard waste does not have enough nutrients to support the growth of BSF larvae. This led to an increase in feeding duration to compensate for nutrient deficiency ( Supriyatna et al . 2018 ).…”

bioconversion of faecal and kitchen waste using black soldier fly larvae (Hermetia illucens):

“…The present study findings from faecal matter varied with Bank et al 2018) values of 200mg/larva/day feeding rate using 1110.4mg DM of BSFL on cassava peels resulted in 30.8 mg (2.77%) larval biomass increase, leaving 1002.08mg (90.24%) of residue and larvae converted 77.52mg (6.98%) to metabolism in 20 days. The lower larval biomass reported by Supriyatna et al (2018) could be ascribed to casava peels used which contained higher amount of lignin-cellulose causing poor substrate digestibility which could have affected the feeding of larvae leading to lower total larval biomass and a lot of residue.…”

“…Mass balance indicates the flow of energy from the feeding substrates into larval biomass, the residue and metabolic processes (Supriyatna et al, 2018). This helps the researcher to know the mass flow (what enters and leaves the treatment system).…”

“…The approach divides the total feed consumed by larvae into the undigested material mass (residue), the mass of the diet feed used for homeostasis and the larval biomass harvested (Manurung et al, 2018). For instance, feeding of 200mg/larva/day using 1110.4mg DM resulted in 30.8 mg (2.77%) larval biomass increase with protein content of 25.7%, leaving 1002.08mg (90.24%) of the residue and 77.52mg (6.98%) of metabolism biomass in 20 days (Supriyatna et al, 2018). Yang and Liu (2014) study recorded 9.58-9.64% larval biomass and 74.45-83.71% residue using 3250 eggs of Chrysomya megacephala in the treatment of 1 kilogram of pig manure.…”

The Influence of Non-Optimal Rearing Conditions and Substrates on the Performance of the Black Soldier Fly (Hermetia illucens)

“…One of the most successful insect species reared at an industrial scale is Hermetia illucens L. due to its versatility in feeding on different substrates. Over the last decade, several studies have been conducted regarding the characteristics of BSFL [ 4 ], production conditions [ 5 , 6 ], substrates used [ 7 , 8 ], feeding regimes [ 9 , 10 ], processing [ 11 , 12 ], and final products [ 13 , 14 , 15 ].…”
