Intestinal health is the single most important driver of performance in modern poultry production. The gut is not only where nutrients are absorbed — it is also the largest immune organ in the bird and the first line of defence against pathogens. When the intestinal barrier is compromised, feed conversion suffers, litter quality deteriorates, and the risk of secondary infection climbs. Protecting gut integrity is therefore central to raising healthy, uniform and profitable flocks.

At VPhS we approach gut health as a system rather than a single intervention. Balanced nutrition, a stable microbiota, effective coccidiosis control and disciplined biosecurity all work together — weakness in one area quickly undermines the others.

Why the intestinal barrier matters

The intestinal lining is only a single cell thick, yet it must simultaneously absorb nutrients and exclude harmful bacteria and toxins. Stressors such as feed changes, mycotoxins, heat and coccidial challenge can loosen the tight junctions between these cells, allowing pathogens to translocate and trigger inflammation. Inflammation is metabolically expensive: energy that should support growth is diverted to the immune response, and feed efficiency falls.

Building a resilient microbiota

A diverse, stable population of beneficial bacteria competes with pathogens for space and nutrients, produces short-chain fatty acids that nourish the gut wall, and helps train the immune system. Supporting that microbiota — through targeted feed additives, gut microbiota regulators and consistent feed quality — is one of the most reliable ways to reduce reliance on antibiotics.

• Maintain consistent feed formulation and particle size to avoid digestive upsets
• Use gut microbiota regulators to promote beneficial bacteria and suppress pathogens
• Control coccidiosis with a well-planned anticoccidial or vaccination programme
• Manage water quality and hygiene as carefully as feed
• Minimise stress at brooding, feed transitions and vaccination

A bird can only express its genetic potential when its gut is healthy. Everything else in the house is built on that foundation.

Conclusion

Strong gut health is not achieved by a single product but by an integrated programme that combines nutrition, microbiota management, parasite control and biosecurity. By treating the intestine as the central hub of flock performance, producers can improve uniformity, lower medication costs and deliver consistently better results.
