Study links sea buckthorn polysaccharide to pigeon biomarkers

Bottom line

A new study in Animals reports that adding sea buckthorn polysaccharide to the diet of tumbler pigeons improved several blood-based markers tied to oxidative stress, inflammation, and metabolism, with the clearest overall effects seen at 200 mg/kg of feed. In the 60-day trial, researchers at Xinjiang Agricultural University assigned 84 male tumbler pigeons to diets containing 0, 100, 200, or 400 mg/kg of effective sea buckthorn polysaccharide. Compared with controls, supplemented birds showed higher antioxidant capacity, shifts in inflammatory cytokines, and lower serum lactate, total cholesterol, and triglycerides at some doses. Serum metabolomics also suggested changes in purine, bile acid, and aromatic amino acid pathways. The paper was published August 24, 2026. (mdpi.com)

Why it matters: For veterinary professionals working with pigeons, aviary birds, or other athletic avian species, the findings add to a growing nutrition literature around plant-derived functional ingredients that may help support physiologic resilience under training or flight demands. But this was a relatively small, single-site study in male tumbler pigeons, and the authors did not show direct improvements in flight performance, clinical outcomes, or long-term safety. That means sea buckthorn polysaccharide is best viewed as an early nutritional signal, not a practice-ready recommendation. Similar sea buckthorn and polysaccharide studies in broilers, ducks, laying hens, and fish have reported antioxidant and anti-inflammatory effects, which gives the pigeon data some biological plausibility.

What to watch: The next step is whether follow-up trials test performance endpoints, dose economics, and safety in broader pigeon populations before breeders or veterinarians can make confident use recommendations. (mdpi.com)

A newly published Animals study suggests sea buckthorn polysaccharide could become another candidate functional feed additive for performance pigeons, after researchers found improved antioxidant markers, altered inflammatory cytokines, and distinct serum metabolomic changes in tumbler pigeons fed the supplement for 60 days. Among the tested doses, 200 mg/kg produced the most pronounced overall response, according to the authors. The paper was published August 24, 2026. (mdpi.com)

The work fits into a broader push to use plant-derived compounds to support health and performance in poultry and other production birds without relying on drug-style interventions. Sea buckthorn is rich in bioactive compounds including polysaccharides, flavonoids, vitamin C, and tocopherols, and prior reviews describe sea buckthorn polysaccharides as having antioxidant, immunomodulatory, and anti-inflammatory activity across in vitro and in vivo models. In avian nutrition, related sea buckthorn studies in broilers, ducks, and laying hens have pointed in the same general direction, including effects on inflammatory markers, lipid metabolism, and antioxidant status.

In the pigeon trial itself, investigators enrolled 84 healthy male tumbler pigeons, about 12 months old, and assigned them to four diet groups: control, 100 mg/kg, 200 mg/kg, or 400 mg/kg effective sea buckthorn polysaccharide. The commercial ingredient used in the diets contained 30% polysaccharide, so inclusion rates were adjusted to reach the target effective dose. According to the study summary and abstract, supplementation increased serum antioxidant capacity and modulated cytokine profiles, while the 200 mg/kg and 400 mg/kg groups also showed lower serum lactate, total cholesterol, and triglycerides than controls. Blood gas, electrolyte, and acid-base variables were largely unchanged. (mdpi.com)

The metabolomics component is part of what makes the paper more than a routine feed-additive report. The authors identified coordinated changes in metabolites linked to purine metabolism, bile acid metabolism, and aromatic amino acid pathways, which they interpret as evidence that the supplement may be affecting systemic metabolic homeostasis rather than only a few isolated serum markers. At the same time, the paper also notes an important limitation: none of the enriched KEGG pathways remained statistically significant after Benjamini-Hochberg correction, so the metabolomic findings should be treated as exploratory rather than definitive.

There does not appear to be a separate institutional press release or broad industry reaction yet, which is not unusual for a niche nutrition paper in pigeons. Still, the findings line up with adjacent poultry research. In broilers, sea-buckthorn flavonoid supplementation has been reported to reduce pro-inflammatory cytokines and improve intestinal health under LPS challenge, while a 2025 review on sea buckthorn polysaccharides summarized evidence for antioxidant, anti-inflammatory, antibacterial, antiviral, and prebiotic bioactivities. Fermented sea buckthorn products have also been reported to improve antioxidant capacity and intestinal health measures in laying hens. (pubmed.ncbi.nlm.nih.gov)

Why it matters: For veterinarians and nutrition professionals, this study is most useful as a marker of where performance-bird nutrition research is heading. It suggests sea buckthorn polysaccharide may have potential as a supportive dietary ingredient for birds exposed to repeated exercise or physiologic stress, especially if the goal is to influence oxidative balance and inflammatory tone. But the evidence is not yet strong enough to justify broad clinical adoption. The study was limited to one breed, one sex, one institution, and surrogate biomarkers rather than hard endpoints such as race performance, recovery time, morbidity, reproduction, or mortality. It also did not address formulation consistency, cost-effectiveness, or regulatory positioning in markets outside China. (mdpi.com)

For companion and specialty avian practice, that means pet parents and breeders may start asking about sea buckthorn-based supplements before the evidence base is mature. Veterinary teams will likely need to frame this carefully: the ingredient is promising, the biologic rationale is plausible, but there is not yet enough evidence to recommend routine use for healthy birds, to predict benefits across species, or to rule out longer-term tradeoffs. The practical question is no longer whether phytogenic additives can move lab markers, but whether those changes translate into meaningful health or performance outcomes in real-world flocks and lofts.

What to watch: Watch for controlled follow-up studies that test flight or competition performance, recovery after exertion, repeatability in females and other pigeon lines, and whether the apparent sweet spot at 200 mg/kg holds up when researchers measure outcomes that matter in practice.
