Abstract

This study aimed to evaluate the in vitro antimicrobial activities of two types of insect fats extracted from black soldier fly larvae (HI, Hermetia illucens L.) and yellow mealworm larvae (TM, Tenebrio molitor L.) and their effects as dietary replacement of soybean oil (S) on cecal fermentation pattern, and fecal and cecal microbiota in rabbits. A total of 120 weaned rabbits were randomly allotted to three dietary treatments (40 rabbits/group) —a control diet (C diet) containing 1.5% of S and two experimental diets (HI diet (HID) and TM diet (TMD)), where S was totally substituted by HI or TM fats during the whole trial that lasted 41 days. Regarding the in vitro antimicrobial activities, HI and TM fats did not show any effects on Salmonella growth. Yersinia enterocolitica showed significantly lower growth when challenged with HI fats than the controls. The insect fat supplementation in rabbit diets increased the contents of the cecal volatile fatty acids when compared to the control group. A metataxonomic approach was adopted to investigate the shift in the microbial composition as a function of the dietary insect fat supplementation. The microbiota did not show a clear separation as a function of the inclusion, even if a specific microbial signature was observed. Indeed, HI and TM fat supplementation enriched the presence of Akkermansia that was found to be correlated with NH3-N concentration. An increase in Ruminococcus, which can improve the immune response of the host, was also observed. This study confirms the potential of HI and TM fats as antibacterial feed ingredients with a positive influence on the rabbit cecal microbiota, thus supporting the possibility of including HI and TM fats in rabbit diets.

  • Lauric acid and glycerol monolaurate can modulate intestinal health by regulating the levels of IL-6 and TNF-α.

    “They can modulate intestinal health by regulating the level of IL-6 and TNF-α (Dabbou et al., 2020)”

    From Insect Derived Lauric Acid as Promising Alternative Strategy to Antibiotics in the Antimicrobial Resistance Scenario (2021) · cites this paper as Dabbou et al., 2020

    The Introduction (page unavailable) says lauric acid can modulate intestinal health and reports that black soldier fly fat reduced gastrointestinal inflammation by modulating IL-6 and TNF-α in turkeys. It does not attribute that cytokine effect specifically to lauric acid or glycerol monolaurate; the latter is not discussed as an agent with that effect. (LLM, conf=0.87)

  • Hermetia illucens oil in growing rabbits significantly lowered growth of Yersinia enterocolitica and positively influenced the cecal microbiota.

    “| HI oil | Growing rabbits | Significantly lower growth of Yersinia enterocolitica, positive influence on the cecal microbiota | Dabbou et al., 2020 |”

    From Insect Derived Lauric Acid as Promising Alternative Strategy to Antibiotics in the Antimicrobial Resistance Scenario (2021) · cites this paper as Dabbou et al., 2020

    The Results (§3.1; page not provided) report significantly lower Yersinia enterocolitica growth in broth challenged with Hermetia illucens fat, not in growing rabbits. The Discussion (§4) suggests a positive effect of dietary insect fats on rabbits’ cecal microbiota, but presents that interpretation cautiously. (LLM, conf=0.90)

    Experimental — accuracy not yet measured
  • The presence of insect-derived lauric acid in animal feed could prevent the use of conventional antibiotics in meat production, limiting the diffusion of microbes harboring antimicrobial resistance genes.

    “The presence of insect-derived LA in animal feed could prevent the use of conventional antibiotics in meat production, limiting the diffusion of microbes harboring AMR genes (Dabbou et al., 2020).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
