Effects of black soldier fly (Hermetia illucens) maggots oil on breeding hens, chicks' quality, and representative epigenetic gene expression.
Article in Poultry science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Dietary oils are energy sources for the growth and reproduction of poultry. Soybean oil (SO) is widely used but competes with the human food supply. In this study, black soldier fly maggot oil (BSFMO) was used as a sustainable alternative to SO for improving breeder hen productivity, chick quality, and immunity. A total of 360 39-week-old Black Yao Chicken 2A breeding hens with an average body weight of 2567 ± 66 g and an egg-laying rate of 70% were randomly allocated to three dietary treatments (n = 120 per group): 2% SO, 2% SO-BSFMO blend (SMO), and 2% BSFMO. After a 5-week feeding trial, 200 eggs per group were incubated, and 120 hatched chicks per group were randomly chosen and reared for 6 weeks. Compared with the SO group, BSFMO significantly increased laying rate, egg weight, egg size, yolk weight, yolk color, and feed conversion efficiency (P < 0.05). The concentrations of follicle‑stimulating hormone, estradiol, triglyceride, and high‑density lipoprotein cholesterol in plasma were increased, while low‑density lipoprotein cholesterol was decreased (P < 0.05). BSFMO also enhanced plasma immunoglobulin A, G, M; interleukin‑2; total antioxidant capacity; superoxide dismutase; and glutathione peroxidase and decreased malondialdehyde (P < 0.05). Chicks from the BSFMO group showed higher quality, growth performance, immune status, hepatic mRNA expression of insulin‑like growth factors (IGF1, IGF2), and epigenetic regulatory genes (DNMT1, DNMT3A) (P < 0.05). In conclusion, maternal feeding with BSFMO improved the productivity and immunity of breeder hens, chick quality, and representative epigenetic gene mRNA expressions of offspring. As an alternative lipid source to soybean oil in animal nutrition, BSFMO can be used in poultry farming for safe and sustainable poultry production and can reduce food competition.
