Optimal gut health is essential for achieving growth and efficient feed utilization in poultry. Under coccidial challenge, a synergisticMulti-herb technology for optimal gut health during coccidial challenge
polyherbal solution helps reinforce intestinal integrity, reduce lesion development, and preserve bird performance.
Maintaining gut health is a major priority in modern poultry production, especially as birds face multiple stressors that compromise intestinal integrity.
The consequences include poor feed conversion, lower body weight gain, and a greater risk of secondary bacterial infections.
While hygiene, litter management, and vaccination help reduce exposure, producers increasingly seek natural alternatives that strengthen intestinal resilience and improve bird performance without relying solely on synthetic anticoccidials.
Plant-based feed additives such as:
are increasingly used to help maintain microbiome balance and support immune defense.
Rather than only eliminating parasites directly, these solutions aim to strengthen the bird’s
natural defenses and improve overall intestinal functionality.
A polyherbal formulation containing saponins, tannins, and flavonoids that helps modulate immune responses, reduce oxidative stress, and preserve intestinal barrier integrity.
An in vitro trial conducted at Poulpharm (Belgium) evaluated the effect of the polyherbal mixture (PHM; NuxaSan 500®) on the viability of:
Four treatments were compared:
Results showed that PHM reduced E. tenella sporozoites by:
For E. maxima, PHM completely eliminated sporozoites within just 24 hours—showing stronger results than salinomycin.
“The polyherbal product completely eliminated E. maxima sporozoites within 24 hours.”
A controlled feeding trial was conducted at the University of Georgia (USA) using
288 day-old Cobb 500 male broiler chicks.
Birds were divided into three groups:
Birds in the challenged groups were orally inoculated with:
PHM was included at 500 mg/kg in the diet.
Eimeria challenge reduced body weight and worsened feed conversion ratio (FCR) in the challenged control group.
Birds receiving PHM showed significantly better growth:
Feed conversion ratio also improved:
PHM supplementation helped birds maintain productive performance while protecting gut structure and reducing lesion severity during Eimeria challenge.
Additional positive effects included:
These findings indicate stronger intestinal integrity and better resilience under protozoal stress.
As poultry production moves toward more sustainable and natural health solutions,
phytogenic additives are becoming increasingly important.
The results from both in vitro and in vivo trials demonstrate that
NuxaSan 500® helps preserve gut integrity, reduce inflammation, support recovery during infection, and maintain overall zootechnical performance.
Most importantly, these benefits were achieved without relying on conventional synthetic anticoccidials.
Multi-herb technology offers a powerful natural strategy to support poultry gut health, improve resilience under coccidial pressure, and protect long-term ortantly, theproductivity.
