Frontiers corrects broiler study on Fructus sophorae extract
Bottom line
A Frontiers in Veterinary Science correction has updated a 2026 broiler nutrition paper examining Fructus sophorae extract supplementation, after the journal said Figure 6 mistakenly included a visible software watermark and Table 6 carried an incorrect unit label for liver antioxidant activity. Frontiers said the underlying raw data and the paper’s scientific conclusions were unchanged, and the original article has been updated accordingly. The underlying study, from researchers at Shandong Agricultural University and industry collaborators, evaluated 100, 150, and 200 mg/kg of the extract in broiler diets and reported improvements in antioxidant markers, nutrient utilization measures, intestinal morphology, and some microbiota-associated findings, while also noting no notable effect on overall growth performance under the study conditions.

Why it matters: For veterinary professionals and poultry nutrition teams, this is a reminder that even relatively minor post-publication fixes, like figure presentation errors or mislabeled units, can matter when papers are being used to assess feed additive claims, compare antioxidant endpoints, or guide formulation decisions. It also sharpens the interpretation of this specific paper: despite the article title’s reference to production performance, the body of the study says growth performance was not notably changed, while antioxidant and gut-health-related measures appeared more favorable in supplemented groups. That distinction matters when veterinarians are weighing phytobiotic ingredients as antibiotic-alternative tools in commercial broiler systems. (frontiersin.org)
What to watch: Watch for whether the authors or other groups publish follow-up trials that clarify dose response, mechanism, and whether these findings translate into consistent field-level performance gains in commercial broiler production. (public-pages-files-2025.frontiersin.org)

Frontiers in Veterinary Science has issued a correction to a recent paper on Fructus sophorae extract supplementation in broiler chickens, updating one figure and one table but leaving the study’s underlying data and conclusions intact. According to the correction notice, Figure 6 in the original publication inadvertently retained a translucent software watermark during final graphic assembly, and Table 6 incorrectly labeled the unit for liver antioxidant activity. The journal said both issues have now been corrected in the updated article. (frontiersin.org)
The corrected paper builds on a broader wave of poultry nutrition research focused on phytobiotics and other non-antibiotic feed additives. As pressure has grown to reduce routine antibiotic growth promoter use, researchers have increasingly studied plant-derived compounds for possible effects on gut health, oxidative stress, and production efficiency. Frontiers’ own article framing and outside review literature both place Fructus sophorae extract within that larger search for “green” or plant-based alternatives that might support broiler resilience and intestinal health. (frontiersin.org)
In the original study, the authors tested basal diets supplemented with 0, 100, 150, or 200 mg/kg of Fructus sophorae extract. They reported improved apparent metabolism of organic matter and crude ash, lower serum alkaline phosphatase, reduced malondialdehyde in serum and liver, and higher superoxide dismutase and serum glutathione peroxidase activity in supplemented groups. The paper also described favorable changes in intestinal morphology and some shifts in cecal microbiota biomarkers. But one nuance stands out: in the discussion, the authors wrote that supplementation at 100 to 200 mg/kg had “no notable influence on broiler growth performance,” suggesting the headline framing around production performance may overstate what was actually observed under the study’s conditions.

The correction itself appears technical rather than interpretive. Frontiers said the watermark was a graphics-preparation oversight, not evidence of AI-generated data analysis, and said the table problem was limited to a mislabeled unit rather than incorrect numerical values. That’s important because it narrows the scope of the correction: readers should understand this as a presentation and labeling fix, not a retraction, data revision, or reversal of the paper’s main claims. (frontiersin.org)
The paper also deserves a careful read because of its author affiliations and disclosures. The study lists researchers from Shandong Agricultural University alongside employees of Shandong Dezhou Shenniu Pharmaceutical Co., Ltd., and Qingdao Huanshan Biotechnology Co., Ltd. The article states those affiliations in its conflict-of-interest section, while also noting public funding from the Shandong Province Key R&D Program. That doesn’t invalidate the work, but it does reinforce the need for independent replication before veterinarians or nutrition teams treat the findings as practice-ready proof. (public-pages-files-2025.frontiersin.org)
Why it matters: For poultry veterinarians, nutritionists, and technical service teams, the bigger takeaway is less about the watermark itself and more about evidence quality. Phytobiotic additives remain a high-interest category because oxidative stress, intestinal integrity, and microbiota balance are central to flock health, especially in antibiotic-reduced systems. Still, this paper illustrates how easily “improved performance” language can travel faster than the underlying detail. If growth performance was not notably changed, the more defensible interpretation is that the extract may have influenced selected biological markers, not yet proven commercial outcomes. (public-pages-files-2025.frontiersin.org)
That distinction matters in the field. Veterinary professionals advising integrators or feed programs need to know whether an additive improves feed conversion, weight gain, livability, or carcass outcomes at scale, not just whether it shifts antioxidant enzymes or microbiota profiles in a controlled trial. Biomarker improvements can be meaningful, especially under stress or disease challenge, but they don’t automatically translate into measurable economic return. The study itself points to that gap by calling for more work on mechanism and, implicitly, on practical applicability. (public-pages-files-2025.frontiersin.org)
What to watch: The next important signal will be whether follow-up studies, ideally independent and conducted under commercial or challenge conditions, confirm the antioxidant and gut-health findings, define the corrected liver antioxidant units clearly in downstream citations, and show whether Fructus sophorae extract can deliver repeatable production benefits beyond laboratory endpoints.
