In poultry production, immunity doesn’t start with vaccines, it begins in the gut. As more producers shift toward antibiotic-free systems, supporting natural immunity is critical. And one of the most effective ways to do that is by improving gut health.

When the gut functions optimally, it not only digests feed efficiently—it trains immune cells, prevents pathogen overgrowth, and builds long-term resilience. This is why modern poultry nutrition strategies are increasingly focused on gut-immune synergy.

Why Gut Health Matters for Poultry Immunity

Over 70% of a bird’s immune system is located in the gastrointestinal tract (GIT). If the gut lining is compromised, or the microbiota is imbalanced, the bird becomes more vulnerable to:

• Bacterial infections like E. coli and Clostridium

• Viral outbreaks with poor vaccine response

• Digestive inflammation leading to poor nutrient absorption

• Systemic stress, increasing mortality and culls

Maintaining gut health means fewer health problems, better growth, and stronger immune performance.

Common Gut Challenges in Poultry Production

• Antibiotic reduction and the rise of resistant pathogens

• Feed changes that disrupt microbial balance

• Mycotoxins and feed hygiene issues

• Early chick stress from transport or poor brooding

• Coccidiosis and enteritis outbreaks

Each of these factors impacts gut structure and microbial balance thereby weakening immune responses.

Postbiotics and XPM in Gut Health Management

One proven strategy is the use of postbiotics, like XPM (Extra Pure Metabolites)—an organic, highly concentrated blend of bioactive metabolites produced through microbial fermentation.

How XPM Supports Gut and Immune Function:

• Balances gut microbiota by suppressing harmful bacteria and promoting beneficial species

• Strengthens intestinal lining, reducing leaky gut and inflammation

• Boosts immune cell signaling, supporting both innate and adaptive responses

• Improves feed digestibility, reducing stress on the digestive system

• Enhances vaccine efficacy by improving immune readiness

  Application in Different Production Systems

  For Broilers:

  • Support early chick gut development

  • Prevent dysbacteriosis and necrotic enteritis

  • Improve feed conversion and weight gain

  For Layers:

  • Maintain gut stability during laying cycles

  • Improve shell quality through better nutrient absorption

  • Reduce disease risks during peak production

  For Breeders:

  • Enhance immunity in both hens and progeny

  • Improve reproductive health and hatchability

   Feed Immunity from the Inside Out

  Better immunity in poultry starts with a healthier gut. By supporting the gut environment and microbial balance, producers can reduce disease outbreaks, cut back on antibiotics, and boost flock resilience—naturally.
