“…An examination of the erroneously classified observations revealed that their lauric acid content was largely higher (∼2.8 times) than the above-mentioned threshold. Such elevated concentration of lauric acid is difficult to explain, given that the intramuscular fat of broilers fed diets based mainly on cereals and soybean meal, as the offered in the studies of de Souza et al [ 42 ] and Kim et al [ 39 ], typically exhibits minimal lauric acid content [ 37 , 43 ]. This is attributable to the scant presence of lauric acid in such type of diets, as supported by several studies [ 25 , 35 , 37 , 43 , 44 ].…”

“…The summed AA contents, including proxies for Trp , allowed enumerating specific protein (SP) concentrations (g/kg DM). Accordingly, profiles of individual AA (g/100 g protein) for BSFL were calculated by accounting for a general literature-based proxy for Trp of 1.8 g/100 g protein in BSFL [ 25 , 36 , 37 , 38 , 76 ]. Similarly, a common constant of 1.2 g Trp /100 g protein was applied to all diets (e.g., [ 36 , 79 ]) to provide merely informative specific protein concentrations of different diets.…”

“…However, variation in nutritional profiles of BSFL may have important consequences on their feeding values [ 3 , 22 ]. Indeed, responses in layer and broiler performance varied when fed formulations containing two different brands of partly defatted BSFL meals and their separately incorporated lipid fractions [ 23 , 24 , 25 ]. Yet, the extent to which these effects may be attributed to different diets used for BSFL fattening or genetic differences between BSF strains remained unclear.…”

Further advancing black soldier fly (BSF) farming for waste valorisation and more sustainable global protein supplies critically depends on targeted exploitation of genotype-phenotype associations in this insect, comparable to conventional livestock. This study used a fully crossed factorial design of rearing larvae of four genetically distinct BSF strains (FST: 0.11–0.35) on three nutritionally different diets (poultry feed, food waste, poultry manure) to investigate genotype-by-environment interactions. Phenotypic responses included larval growth dynamics over time, weight at harvest, mortality, biomass production with respective contents of ash, fat, and protein, including amino acid profiles, as well as bioconversion and nitrogen efficiency, reduction of dry matter and relevant fibre fractions, and dry matter loss (emissions). Virtually all larval performance and body composition traits were substantially influenced by diet but also characterised by ample BSF genetic variation and, most importantly, by pronounced interaction effects between the two. Across evaluated phenotypes, variable diet-dependent rankings and the lack of generally superior BSF strains indicate the involvement of trade-offs between traits, as their relationships may even change signs. Conflicting resource allocation in light of overall BSF fitness suggests anticipated breeding programs will require complex and differential selection strategies to account for pinpointed trait maximisation versus multi-purpose resilience.

“…2 in abdominal fat content also showed significant quadratic effects of BSFLM indicating that its effects were non-linear on the variable after a certain level in diet (7.5%). BSFLM is rich in saturated fatty acid (lauric acid) content and its feeding obviously leads to increased carcass lauric acid content (Heuel et al 2022).…”

“…Live BSF larvae, when scattered on the litter, increased levels of welfare and behaviour, and improved leg health in broiler chicken (Ipema et al 2020). Organic broilers fed diet containing BSF larva, but with 20% less lysine content, grew equally well as that of control (Heuel et al 2022). The BSF larva also might favourably influence immunity and survivability against Salmonella gallinarum (Lee et al 2018).…”

Four samples of Black soldier fly (Hermetia illucens) larva meal (BSFLM), procured from 3 different sources, were analysed for nutrient profile. One of those, a partially-defatted BSFLM, was evaluated in male broiler chicken diet at 0, 2.5 and 5.0% (expt. 1), and at 0, 5.0, 7.5 and 10.0% levels (expt. 2). Each of the experimental diets was fed to 12 replicates of 6 chickens each in expt. 1 (n=216) and 15 replicates of 25 chickens each in expt. 2 (n=1500). The nutrient profile varied greatly amongst the BSFLM samples (crude protein: 49.8 to 59.6%, crude fat: 12.0 to 38.4%, lysine: 2.4-4.7%, methionine: 2.3-4.6%, lauric acid: 15.2-62.4%). Body weight gain (BWG) and feed intake (FI) of broilers increased linearly in the groups fed BSFLM upto 5.0% during 0-3 weeks of age (expt. 1) and was similar during the remaining period, whereas the feed conversion ratio (FCR) linearly increased during 3 to 5 weeks. At higher levels of BSFLM (≥7.5% in diet) (expt. 2), significantly depressed BWG and FI, and increased FCR were observed. Dressing yield, breast weight and abdominal fat content linearly increased with BSFLM level in diet (expt. 2), while other organ weights, serum biochemical profile and PHA-P response were unaffected (expt. 1). It is concluded that the nutrient profile of BSFLM varied with the source and it could be used upto 5% in the diet of broiler chickens with beneficial effects on growth during the early life.
