Metabolic performance and feed efficiency of black soldier fly larvae

Frontiers in Bioengineering and Biotechnology, Год журнала: 2024, Номер 12

Опубликована: Апрель 30, 2024

The black soldier fly (BSF), Hermetia illucens , is used in entomoremediation processes because its larvae can use a variety of organic residues with high efficiency. However, feed efficiencies are variable and characterized by uncertainties. Recently developed growth metabolic performance models have predicted across different studies that BSF 53%–58% the components they assimilated, terms carbon equivalents, for throughout their lifetime when reared on chicken feed. This termed average net remainder has been lost as CO 2 . mass balances made under similar conditions show weight gained corresponds to only 14%–48% substrates removed, indicating substrate conversion Both indicators even greater variability if more considered. Feed assimilation rates, costs growth, maintenance, larval lifespan shown affect how efficiently convert into growth. differences between further indicate often not optimally overall yield such determined alone but result interactions larvae, substrates, microbes, physical environment. purpose this study illustrate quantification help improve our understanding role processes.

Metabolic Performance of Mealworms and Black Soldier Fly Larvae Reared on Food and Agricultural Waste and By-Products

Mealworms and black soldier fly (BSF) larvae are two of the most reared insects at an industrial scale. Both may feed on by-products from agricultural food industries. Feed efficiency is one important aspects such processes varies between species substrates depends metabolic performance larvae. Compared to each other, both hold advantageous capabilities affecting their efficiency, likely depending substrate. We mealworms BSF a diverse selection industries, quantified major rates across life spans, compared performances. The type had stronger effects growth than Generally, were in terms highest maximal specific rate (0.50–0.77 day−1) assimilation (0.81–1.16 shortest development period (23–25 days) but disadvantageous maintenance cost (0.07–0.21 day−1). In mealworms, 0.02–0.11 day−1, 0.16–0.37 was least 65–93 days, while only 0.02–0.05 day−1. contrast larvae, weight dependent lowest largest individuals. combined outcome these resulted average carbon net NGE*avg 0.16–0.40 0.33–0.56 span.

Chitin: a comparison between its main sources

Frontiers in Materials, Год журнала: 2025, Номер 12

Опубликована: Март 4, 2025

Chitin is the second most abundant polysaccharide on Earth, after cellulose, and it mainly obtained from shells of crustaceans. While chitin currently derived shrimp shells, there a growing interest in commercializing sourced insects. This review compares various sources, including crustaceans, insects, fungi, mollusks, based several factors: purity, molecular weight, crystallinity, cost, sustainability. Although crustaceans yield higher amounts exhibit better insects present significant advantages terms sustainability, ease extraction, lower impurity levels. emerging as sustainable alternative due to its simpler extraction processes reduced environmental impact. work highlights increasing potential reliable source for production.

Abstract Chitosan (CS), which is extracted from insects, especially black soldier fly (BSF) ( Hermetia illucens ), currently considered a latent source. The present work chitin and CS using chemical method the two life stages of BSF, including dead cocoon. initial materials were deproteinized with 5% NaOH, demineralized 4% HCl, decolorized 1% KMNO 4 to obtain chitin. obtained was deacetylated 70% NaOH gain CS. yield (%) 9.72 - 37.03%, BSF cocoons having highest yield. isolated then transformed into by soaking it in at 80°C for 8 h. Notably, produced met commercial standards, low mineral protein content (< 1%). physicochemical functional properties evaluated through deacetylation degree (DDA), viscosity, solubility, molecular weight (MW), FTIR spectrum, SEM images. spectrum found that chitins effectively converted CS, while micrograph implied honeycomb-like surface structure characteristic derived BSF.

Substituting the fishmeal with solid-state-fermented Black soldier fly (Hermetia illucens) larvae meal in GIFT tilapia (Oreochromis niloticus) fry diet: Effects for growth performance, carcass composition and liver histology

Abstract Replacing fishmeal (FM) with an optimal aquafeed alternative remains a significant challenge. Recent research suggests that insect meal is potential candidate ingredient for substitute fishmeal. Simultaneously, the Black soldier fly larvae (BM) intensively researched promising results. However, controversial results and inability to complete FM substitution prompt further investigation into new techniques. Solid-state fermentation (SSF) has been identified as cost-effective technique enhance efficiency of aqua feed ingredients. Therefore, nine-week experiment was conducted using fermented black (FB) replace based on protein content 0% (0FB), 35% (35FB), 70% (70FB), 100% (100FB) in diet GIFT tilapia ( Oreochromis niloticus ) fry (0.18±0.01 g/fish) applying SSF. Additionally, entirely replaced by unfermented (UB), including (100UB). Results weight gain (WG), daily (DWG), relative (RWG), specific growth rate (SGR) FB-fed fish were statistically higher (P<0.05) than those UB-fed fish. there decreasing trend performance when FB proportion increased. ratio (FCR) (PER) all lower control. Further, 100UB exhibited reduced values WG, DWG, PER, underscoring positive effect carcass composition analysis showed SSF did not adversely affect crude protein, ash, fiber contents. lipid decreased increasing levels FB. Histopathological alterations liver tissues fed FBSFM-included diets highlight importance screening rearing surfaces ensure safety. Overall, BM viable option substituting O. without affecting utilization.

Hermetia illucens or black soldier fly (BSF) is one of the edible insects with potential to replace animal protein in feed. This study aimed compare effect microwave oven drying and vacuum on its biochemical, antioxidant physicochemical properties BSFP produce shelf-stable BSF larvae were fed fruit waste until prepupal stage subsequently prepupae harvested for process using microwave-oven (MD-BSFP) vacuum-oven (VD-BSFP). Based experimental result, crude VD-BSFP (31.00%) was higher than MD-BSFP (16.90%) which significantly different at p < 0.05. Furthermore, proportion EAA total amino acids (E/T) attained (24.64%) that (7.86%). In addition, (12.0 ± 3.0%) had free radical scavenging activity (5.7 0.2%) conclusion, VD more preferable MD as a procedure powder lower moisture content, content properties.
