“…Nevertheless, BSF larvae can be enriched in PUFA n3 through the substrate . Authors reported that C12:0 is a good inhibitor of bacterial strains and could be of great interest in the reduction of the use of antibiotics in animal feeding . In this context, BSF larvae reared on organic wastes showed very interesting results, with up to 574 g kg −1 TFA of lauric acid.…”

“…The enhanced antioxidant response might be related to the content of chitin and its derivatives found in the insect exoskeleton (Li et al, ; Ogunji et al, ; Taufek et al, ). Additionally, the medium‐chain FA lauric acid of the BSF larvae has been shown to have an antibacterial activity in pigs (Spranghers et al, ). The expression of heat‐shock protein‐70 and superoxide dismutase was, however, not affected by using the insect ingredients in the current trial.…”

Insect-based diets high in lauric acid reduce liver lipids in freshwater Atlantic salmon

We evaluated the effect of a diet containing insect meal and insect oil on nutrient utilization, tissue fatty acid profile and lipid metabolism of freshwater Atlantic salmon (Salmo salar). Insect meal and insect oil from black soldier fly larvae (Hermetia illucens, L.; BSF), naturally high in lauric acid (12:0), were used to produce five experimental diets for an eight-week feeding trial. 85% of the dietary protein was replaced by insect meal and/or all the vegetable oil was replaced by one of two types of insect oil.A typical industrial diet, with protein from fishmeal and soy protein concentrate (50:50) and lipids from fish oil and vegetable oil (33:66), was fed to a control group.The dietary BSF larvae did not modify feed intake or whole body lipid content.Despite the high content of saturated fatty acids in the insect-based diets, the apparent digestibility coefficients of all fatty acids were high. There was a decrease in liver triacylglycerols of salmon fed the insect-based diets compared to the fish fed the control diet. This is likely due to the rapid oxidation and low deposition of the medium-chain fatty acid lauric acid.

“…The interest of using insects in animal feed is increasing [35,36], and inclusion of BSFL have been investigated in diets for pigs [9], chicken [12] and sh [11,37], but to this date, there is limited information about the effect of high dietary inclusion levels. The present study demonstrated that up to 19.06% fullfat BSFL meal can be included as an alternative protein and energy source in pelleted diets for weaned piglets without affecting growth performance.…”

Background: Weaning is associated with growth decline and morphological changes in the gastrointestinal tract of the pig. Insects, such as the Black soldier fly larvae (BSFL), are suggested as a sustainable novel protein source in diets for pigs. They contain chitin, medium chained fatty acids, and anti-microbial peptides, which could improve the gastrointestinal function and health in the post-weaning pig. The objective of this study was therefore to investigate the effect of increasing inclusion of full-fat BSFL in diets for post-weaning pigs on growth performance parameters, digestibility, gut morphology, and the microbial community in the colon. Eighty crossbred weanling pigs were weaned at approximately 32 days of age, with an average weaning weight of 10.6 ± 0.8 kg. For four weeks, the pigs were fed one of four dietary treatments: a control diet or one of three diets containing an increasing amount of full-fat BSFL meal: 4.76% (BSFL5), 9.52% (BSFL10), and 19.06% (BSFL20). Results: Increased level of full-fat BSFL in the diet did not affect growth performance or fecal consistency. A reduction in apparent total tract digestibility (ATTD) of crude protein (P = 0.035) was found for increased inclusion of BSFL, whereas the ATTD of crude fat increased (P<0.001). Jejunal, ileal, or colonic morphometry was not affected by the BSFL inclusion. Some changes in the colon microbiota were observed, but no differences in the short-chain fatty acid concentrations were detected between the dietary treatments. At the phylum level, dietary treatment affected the relative abundance of Bacteroidota, Firmicutes, Campilobacteria, and Thermoplasmatota, but there was no clear pattern relationship with the BSFL inclusion level. At the genus level, the inclusion of BSFL in the diet reduced the relative abundance of Lactobacillus (P = 0.015) compared to the control. Conclusions: Collectively, the results indicate that up to 19.06% of full-fat BSFL meal could be included in a balanced diet for PW pigs without affecting growth performance, gut function, or health.
