Abstract: Background The possibility of partially replacing soybean meal (SBM) with Hermetia illucens (HI) defatted larvae meal in broiler nutrition has frequently been suggested. For sustainability reasons, however, the larvae fat produced during defatting should also be used and could be particularly beneficial regarding gut health due to its fatty acid composition. To evaluate the suitability of HI larvae as protein and fat source, a 2 × 3 factorial arrangement with two types of protein, i.e. SBM (S) … Show more

“…This assumption is supported by our observation that the ileal digestibility of crude fat was very high (approximately 90% in all groups) and the fact that TG-bound MCFA are hydrolysed and absorbed more rapidly than TG-bound long-chain fatty acids due to easier emulsification and less dependence on pancreatic lipase activity [ 27 , 28 ]. In agreement with this, an increased ileal fat digestibility has been observed in a recent study with broilers by dietary substitution of soybean oil by HI fat [ 20 ]. Nevertheless, reports exist demonstrating that short-term administration of specific MCFA, such as caprylic acid (C8:0) and 1-monoglyceride of capric acid (C10:0), via the feed or the drinking water reduces cecal colonization of pathogenic bacteria, such as Campylobacter jejuni , after artificial infection [ 22 , 23 , 57 ].…”

“…In contrast to insect meal, the feed potential of insect fat is far less explored. Despite that several studies have demonstrated that TM or HI fat has no negative impact on performance, gut morphology, selected blood parameters and product quality in broilers, laying hens and turkeys [13][14][15][16][17][18][19][20][21], knowledge about the suitability of insect fat as a fat source in broiler diets is still limited. In particular, in-depth analysis of the effects of insect fat on the gut microbiome and intermediary metabolism is lacking.…”

“…At the fifth instar of development, larvae are collected and ready for use as feed for animals ( Dortmans et al, 2017 ). If processed, the larvae are dried and ground into a high-quality, sustainable meal to replace conventional protein sources for food and animal feed, most commonly soybean meal and fish meal ( Giannetto et al, 2020 ; Hartinger et al, 2022 ). Another application is to extract fat from larvae and apply this subproduct as soy oil replacement for animal supplements ( Kim et al, 2022 ), personal care products such as shampoo, detergent, and soap ( Franco et al, 2022 ), and biodiesel production ( Surendra et al, 2016 ; Lee, Yun & Goo, 2021 ).…”
