Chicory extract study points to gut and immune benefits in broilers
Bottom line
A new paper in Animals reports that chicory aqueous extract may help broiler chickens maintain antioxidant status, immune function, and intestinal health, while also performing better than florfenicol on several physiological measures in the study design. In the trial, chicks were assigned to a control group, a florfenicol group, or low-, medium-, and high-dose chicory extract groups delivered in drinking water. According to the study abstract and an indexed summary of the full paper, florfenicol exposure was associated with poorer feed conversion, lower average daily gain, reduced immune indices, and weaker jejunal morphology, while chicory extract improved several of those markers, with the medium dose, reported as 2.5 g/L, showing the strongest overall effect.

Why it matters: For veterinary professionals working in poultry production, the study adds to a growing body of evidence around phytogenic additives as partial alternatives to routine antibiotic use. Earlier poultry research has linked chicory and other plant-derived additives to improvements in gut morphology, immune markers, and antioxidant capacity, while separate broiler and laying hen studies have reported that florfenicol can disrupt intestinal homeostasis and increase oxidative or hepatic stress under some exposure conditions. That doesn’t make chicory a replacement for therapeutic antibiotics in disease treatment, but it does strengthen interest in non-antibiotic tools that may support gut health and resilience in commercial flocks.

What to watch: The next step is whether follow-up studies validate these findings under commercial field conditions, define mechanism and dosing more clearly, and test whether chicory extract can reduce antibiotic use without compromising disease control. (dyjz.cbpt.cnki.net)
A newly published Animals study is putting chicory aqueous extract on the radar as a potential poultry health support tool. The paper, titled The Effects of Chicory Aqueous Extract on Antioxidant Capacity, Immune Response, and Intestinal Function in Broilers, compared chicory extract in drinking water with florfenicol exposure in young broilers and found that the plant extract improved multiple performance, immune, and gut-health measures, while the florfenicol group showed deterioration in several of the same markers.

The backdrop is familiar to poultry veterinarians: pressure to reduce routine antibiotic use without losing control of enteric health, performance, and early-life stress. The study authors frame florfenicol as widely used in broiler production, but also note concern that antibiotic exposure can trigger physiological changes in birds. That concern is supported by prior literature. Recent broiler and laying hen studies have linked florfenicol exposure with dysbiosis, impaired intestinal homeostasis, oxidative stress, hepatocyte apoptosis, renal injury, and greater susceptibility to systemic infection under some conditions.

In the new study, chicks were divided into five groups: a blank control, a florfenicol group, and low-, medium-, and high-dose chicory aqueous extract groups. The indexed summary says the trial ran for six days and evaluated serum markers, immune organs, liver and kidney indices, and intestinal tissue. Compared with controls, the florfenicol group had significantly higher feed conversion ratio, liver and kidney indices, AST, ALT, uric acid, urea nitrogen, creatinine, hepatic TNF-α, and malondialdehyde, while average daily gain, average daily feed intake, bursa index, IgG, IgM, jejunal villus height, villus-to-crypt ratio, and lipase activity fell. By contrast, chicory extract increased average daily gain and selected immune and digestive measures, and the medium-dose group, reported as 2.5 g/L, produced the most consistent benefits across performance, IgA and IgG, thymus index, jejunal villus-to-crypt ratio, and digestive enzyme activity.

That finding fits with the broader chicory literature in poultry, though formulations and study designs vary. Previous broiler work has associated chicory supplementation with improved gut histomorphometry, better growth performance, favorable shifts in immune-related parameters, and stronger antioxidant status. A 2022 Scientific Reports paper on aqueous extracts from Cichorium intybus roots similarly found benefits for growth, liver function, lipid profile, and antioxidant activity in broilers, while other studies have suggested chicory root powder can improve gut microflora and intestinal morphology enough to be discussed as an alternative to antibiotic growth promoters.

Direct outside commentary on this specific paper wasn’t readily available at the time of writing, which isn’t unusual for a just-posted nutrition study. Still, recent reviews and book chapters on poultry nutrition describe chicory as a promising phytogenic ingredient because of its inulin-type fructans, polyphenols, and potential prebiotic effects on the microbiota-gut-immune axis. Those reviews stop short of presenting chicory as a one-to-one antibiotic substitute, but they do place it in the larger movement toward phytogenics, probiotics, and other non-antibiotic feed or water additives in broiler systems.

Why it matters: For veterinarians and poultry health teams, this paper is less about replacing florfenicol in treatment protocols and more about expanding the evidence base for preventive nutrition and flock resilience. If chicory aqueous extract can reliably support intestinal morphology, digestive enzyme activity, and humoral immune markers in early-life broilers, it may become part of broader antibiotic-reduction programs, especially where producers are looking to lower routine exposure while preserving performance. But the study also appears short in duration and focused on physiological endpoints rather than field-level disease outcomes, so it should be interpreted as hypothesis-building rather than practice-changing on its own. (dyjz.cbpt.cnki.net)
There are also practical questions still unanswered for the field: how the extract is standardized, whether the active effect comes from inulin, polyphenols, or another fraction, how stable the product is in drinking water, and whether results hold across breeds, diets, stressors, and commercial housing conditions. Regulatory and market uptake will likely depend on those details, plus cost, supply consistency, and reproducibility across independent trials. (mdpi.com)
What to watch: Expect interest in larger commercial validation studies, dose-confirmation work around the reported 2.5 g/L sweet spot, and mechanistic research on whether chicory’s main value is antioxidant protection, immune modulation, microbiome effects, or some combination of the three.
