Microwave-dried black soldier fly larvae enhance growth, intestinal health, and humoral immunity in broiler chickens: A functional feed approach.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background and Aim: The global demand for sustainable animal protein sources has led to the exploration of insects as alternative feed ingredients. Among these, black soldier fly (BSF) larvae ( Materials and Methods: A total of 160 unsexed Lohmann broiler chickens were randomly allocated to five dietary treatments (T0-T4), with MDBSFM supplementation levels of 0%, 0.25%, 0.50%, 0.75%, and 1.00%, respectively. Each treatment consisted of four replicates, each with eight birds. Growth performance metrics, organ weights, intestinal histomorphology, immunoglobulin levels (IgA and IgY), and IGF-1 mRNA expression were measured. Fatty acid composition of MDBSFM was analyzed by gas chromatography. Results: MDBSFM supplementation significantly improved body weight gain, final body weight, and feed conversion ratio (p < 0.05), with optimal outcomes observed at 0.75% inclusion. Villus height in the ileum was markedly increased in the 0.50% and 0.75% groups (p < 0.01), suggesting enhanced nutrient absorption. IgA and IgY concentrations were significantly elevated in response to MDBSFM (p < 0.05), particularly in the T3 and T4 groups. Although IGF-1 mRNA expression did not differ significantly (p = 0.58), the highest fold change (1.54) was noted in the 1.00% group. Conclusion: Microwave-dried BSF larvae meal represents a promising functional feed additive capable of improving growth, intestinal health, and humoral immune responses in broilers without adverse effects. The high lauric acid content and bioactive compounds in MDBSFM may contribute to these beneficial effects. While IGF-1 upregulation trends warrant further molecular investigation, MDBSFM offers a viable alternative to antibiotic growth promoters in poultry diets. Future research should focus on microbiota profiling and large-scale commercial validation.
