Frontiers corrects nano zinc broiler review to add funding source
Bottom line
Frontiers in Veterinary Science has published a correction to a September 17, 2026 review on nano zinc supplementation in broiler nutrition, stating that funding from the State Scientific Institution NIIMMP, grant RSF No. 22-16-00041-P, was mistakenly left out of the original article. The correction, published October 13, 2026, says the original version has now been updated. The underlying review examined evidence that nano zinc may support broiler growth, intestinal health, immune function, and oxidative stress management, while also highlighting gaps in the literature. (frontiersin.org)
Why it matters: For veterinary professionals and poultry nutrition teams, this is a transparency update rather than a change to the science itself. Still, funding disclosures matter in fast-moving areas like nanomineral feed additives, where claims around bioavailability, gut health, and sustainability can influence research priorities and commercial interest. Broader literature continues to suggest potential performance and gut-health benefits from nano zinc in broilers, but recent reviews and primary studies also stress dose sensitivity, uneven study quality, and the need for more standardized, field-relevant data. (frontiersin.org)
What to watch: Watch for whether future broiler nano zinc studies include clearer disclosure, standardized dosing comparisons, and more commercial-scale validation. (pubmed.ncbi.nlm.nih.gov)
A new correction in Frontiers in Veterinary Science does not alter the conclusions of a recent review on nano zinc in broiler diets, but it does fix an important omission: the original paper failed to disclose funding from the State Scientific Institution NIIMMP under RSF grant No. 22-16-00041-P. The correction was published October 13, 2026, and the journal says the original article has been updated. (frontiersin.org)
The corrected article is a review published September 17, 2026 in the journal’s Animal Nutrition and Metabolism section. According to PubMed and the journal listing, the paper set out to summarize current evidence on nano zinc’s biological functions and applications in broiler nutrition, discuss proposed mechanisms of action, critically assess the literature, and identify priorities for future research. (pubmed.ncbi.nlm.nih.gov)
That context matters because nano zinc has drawn sustained interest as poultry producers and nutrition researchers look for ways to improve mineral bioavailability, gut integrity, immune performance, and feed efficiency while potentially lowering inclusion rates versus conventional zinc sources. A 2024 meta-analysis found that zinc nanoparticles were associated with improvements in growth performance and related outcomes compared with conventional supplementation in broilers, while a 2026 Frontiers Microbiology study reported better growth performance, jejunal morphology, and some microbiota changes at a 25 mg/kg Nano-ZnO inclusion level, with less benefit at higher doses. (pubmed.ncbi.nlm.nih.gov)
The correction itself is narrow. Frontiers states that the omitted item was the funder, State Scientific Institution NIIMMP, grant RSF No. 22-16-00041-P, and that the article has been updated accordingly. There is no indication in the notice that the paper’s scientific content, interpretation, or conclusions were changed. In other words, this is a disclosure fix, not a data correction or retraction. (frontiersin.org)
Industry and academic commentary around nano zinc remains broadly interested but cautious. Review literature has repeatedly described nano zinc as more bioavailable than conventional inorganic sources and potentially useful for intestinal health, antioxidant status, and immune response, but those same reviews emphasize that results vary by formulation, dose, bird age, and study design. The 2026 broiler microbiota paper, for example, reported favorable effects at one inclusion level and specifically noted that higher concentrations did not deliver the same benefit, reinforcing that “nano” does not automatically mean “better” across doses.

Why it matters: For veterinarians, poultry technical teams, and feed decision-makers, the main takeaway is about research governance as much as nutrition science. Funding disclosures help readers judge possible sources of influence, especially in areas where new feed technologies may move quickly from experimental work into product development and marketing. The correction does not undermine the review’s topic, but it is a reminder to read nano zinc claims alongside the broader evidence base, which still points to promise tempered by variability, formulation effects, and unanswered questions about optimal dosing, safety margins, and real-world economics. (frontiersin.org)
There is also a practical veterinary angle. Zinc remains essential in broiler nutrition, and newer delivery systems may eventually help reduce waste or improve intestinal and immune outcomes, but the available literature is still a mix of reviews, controlled studies, and meta-analyses rather than a settled commercial standard. For professionals advising integrators or feed programs, that means watching not just efficacy claims, but also reproducibility, formulation-specific effects, and whether benefits hold up under commercial production conditions. (pubmed.ncbi.nlm.nih.gov)
What to watch: Next, look for follow-up work that compares nano zinc against conventional and organic zinc sources under commercial conditions, clarifies safety and dose-response thresholds, and maintains stronger transparency on funding and competing interests. (pubmed.ncbi.nlm.nih.gov)
