Digestive Health in Poultry: A Key Pillar for Profitable and Sustainable Production

In the context of modern poultry farming, where productive efficiency and animal welfare are gaining increasing prominence, digestive health is positioned as one of the fundamental pillars to guarantee profitability, sustainability, and resilience against health and environmental challenges.

A functional gastrointestinal tract (GIT) is much more than a simple nutrient absorption organ: it acts as the nerve center of multiple physiological processes essential for intestinal health in birds.

Its proper functioning directly affects growth, feed conversion, immunocompetence, and disease resistance. Therefore, implementing strategies aimed at preserving and optimizing digestive health is a priority in poultry management, nutrition, and health programs, especially to prevent enteritis.

The Central Role of Intestinal Microbiota in Digestive Function

One of the most determining elements in the digestive balance of birds is the intestinal microbiota: a dynamic microbial ecosystem that decisively influences digestion, immunity, and defense against pathogens.

Composition and Function

The avian microbiota consists of a wide diversity of bacteria, fungi, viruses, and protozoa that interact with each other and with the host. Beneficial species —such as Lactobacillus spp., Bifidobacterium spp., or Saccharomyces spp.— are crucial for maintaining intestinal health in birds and preventing intestinal diseases. They ferment non-digestible substrates, leading to the production of short-chain fatty acids (SCFAs), which regulate intestinal pH, improve nutrient absorption, and strengthen epithelial integrity.

Additionally, a balanced microbiota acts as a barrier against pathogenic microorganisms through competitive exclusion mechanisms, production of antimicrobial substances, and modulation of the mucosal immune system.

Imbalance Factors

The microbiota composition is subject to variations induced by multiple factors: animal age, diet type, water quality, antimicrobial use, environmental conditions, or heat stress exposure. The latter, in particular, can induce dysbiosis and increase intestinal permeability, compromising barrier function and favoring intestinal diseases.

Tools for Modulation

Today, the nutritional approach offers multiple alternatives to restore or preserve microbial balance without resorting to antibiotics:

• Prebiotics: Non-digestible fermentable fiber that acts as a specific substrate for the growth of beneficial bacteria. Notable examples are FOS, MOS, and β-glucans.
• Probiotics: Live microorganisms that, when administered in adequate amounts, confer a beneficial effect on the host. The selection of strains resistant to the gastrointestinal tract with proven efficacy is crucial.
• Postbiotics: Metabolites derived from microbial activity (such as SCFAs, antimicrobial peptides, enzymes, etc.) that exert positive effects even in the absence of viable microorganisms, providing stability and functionality that can improve intestinal health in birds and reduce health-related problems.
• Phytobiotics: Bioactive compounds of plant origin, such as essential oils or standardized extracts, that have antimicrobial, anti-inflammatory, and intestinal microbiota modulating properties that contribute to intestinal health in birds and improve digestion and nutrient absorption.

Intestinal Mucosa Integrity: The Internal Defensive Wall

Beyond the microbiota, digestive health is based on the structural integrity of the intestinal mucosa, which acts as a physical, immunological, and biochemical barrier that prevents the entry of pathogens and toxins into the organism.

Architecture and Functionality

The intestinal mucosa is composed of epithelial cells joined by tight junction complexes, whose function is to regulate the selective passage of molecules. These junctions are reinforced by a mucus layer and local immune elements, forming a dynamic barrier that protects the organism against external aggressions.

Common Pathogens

Factors such as enteric infections, mycotoxins, cellular oxidation, or poorly formulated diets can deteriorate this barrier, causing intestinal hyperpermeability (“leaky gut”), chronic inflammation, and reduced digestive efficiency.

Nutrients and Additives for Maintenance

• Functional amino acids like glutamine and arginine favor proliferation and repair of the intestinal epithelium, improving digestion and nutrient absorption.
• Short-chain fatty acids like butyrate exert trophic effects on enterocytes, improving intestinal morphology and function.
• Natural antioxidants (vitamins C and E, selenium, polyphenols) protect against oxidative stress, reducing cellular damage.
• Functional additives like organic acids or essential oils promote a more stable intestinal environment, controlling inflammation and stimulating epithelial regeneration.

Digestive Immunity and Control of Infectious Agents

The digestive system also plays a front-line immunological role, acting as an interface between the external environment and the bird’s immune system. Infectious diseases —bacterial, viral, or parasitic— represent a continuous threat, especially under high-density or low-biosecurity conditions.

Preventive Approach

Biosecurity: This is the foundation of any prevention program. It requires rigorous control of access to facilities, cleaning and disinfection, vector control, and adapted vaccination plans.

Vaccination: Specific vaccines allow reducing the incidence and severity of common enteric diseases such as coccidiosis, clostridiosis, or salmonellosis.

Nutritional Management: Alternative additives with immunomodulatory and antimicrobial effects are increasingly used as support tools:

• Organic acids: Inhibit pathogenic bacteria growth by reducing intestinal pH.
• Phytobiotics: Have activity against a wide range of pathogens and favor immune balance.
• Bacteriophages: Specific viruses that attack pathogenic bacteria, offering a selective alternative.
• Antimicrobial peptides: Act on bacterial membranes without generating residues or resistance.

Rational Use of Antibiotics: Their use should be limited to justified cases and under veterinary prescription, as part of a responsible use approach against the growing risk of antimicrobial resistance in the context of intestinal health in birds.

Diet Optimization for Healthy Digestion

Feed formulation should not only meet the nutritional requirements of birds but also actively support digestive function. A poorly designed diet can generate unwanted fermentations, dysbiosis, and inflammatory processes.

Keys to a Functional Diet

Raw material quality: Ingredients with high digestibility reduce the presence of undigested substrates that could be fermented by undesirable bacteria.

Particle size: Influences intestinal transit time and the efficiency of enzymatic digestion, especially in the proventriculus and gizzard.

Use of exogenous enzymes: The incorporation of phytases, proteases, and carbohydrases allows improving nutrient availability, reducing fermentable residues and improving intestinal health to optimize digestion and absorption in the intestinal tract of birds.

Mycotoxin control: These fungal toxins have a deleterious effect on the intestinal mucosa and immunity. The use of mycotoxin binders is key in regions with high risk of raw material contamination.
