Probiotics and prebiotics play a crucial role in improving gut health and performance in poultry by enhancing digestion, boosting immunity, and promoting beneficial gut microbiota. Here’s how they work:

Probiotics

Probiotics are live beneficial microorganisms (such as Lactobacillus, Bifidobacterium, and Bacillus species) that, when administered in adequate amounts, provide health benefits by:

1. Balancing Gut Microflora – Competing with harmful bacteria (e.g., Salmonella, E. coli) for space and nutrients, thereby reducing disease risks.

2. Enhancing Digestion & Nutrient Absorption – Producing digestive enzymes that improve feed utilization and conversion efficiency.

3. Boosting Immune Response – Stimulating gut-associated lymphoid tissue (GALT) to improve immune function.

4. Reducing the Need for Antibiotics – Serving as natural alternatives to antibiotic growth promoters (AGPs).

Prebiotics

Prebiotics are non-digestible feed ingredients (such as fructooligosaccharides, mannan-oligosaccharides, and inulin) that selectively feed beneficial gut bacteria. Their benefits include:

1. Promoting Growth of Beneficial Bacteria – Encouraging the proliferation of probiotics, leading to better gut balance.

2. Enhancing Gut Integrity – Strengthening intestinal barriers, reducing leaky gut syndrome.

3. Improving Performance & Feed Efficiency – Increasing energy and nutrient utilization, leading to better weight gain and egg production.

Probiotics and prebiotics contribute to gut health and performance in poultry by introducing beneficial bacteria into the intestinal tract, promoting a balanced microbiome, enhancing nutrient absorption, and supporting the immune system, ultimately leading to improved growth, feed efficiency, and overall bird health by outcompeting harmful pathogens and creating a favorable environment for digestion; probiotics provide the live beneficial bacteria, while prebiotics act as a food source for these bacteria to flourish within the gut.

The gut microbiota has been designated as a hidden metabolic ‘organ’ because of its enormous impact on host metabolism, physiology, nutrition, and immune function. The connection between the intestinal microbiota and their respective host animals is dynamic and, in general, mutually beneficial. This complicated interaction is seen as a determinant of health and disease; thus, intestinal dysbiosis is linked with several metabolic diseases. Therefore, tractable strategies targeting the regulation of intestinal microbiota can control several diseases that are closely related to inflammatory and metabolic disorders. As a result, animal health and performance are improved. One of these strategies is related to dietary supplementation with prebiotics, probiotics, and phytogenic substances. These supplements exert their effects indirectly through manipulation of gut microbiota quality and improvement in intestinal epithelial barrier. Several phytogenic substances, such as berberine, resveratrol, curcumin, carvacrol, thymol, isoflavones and hydrolyzed fibers, have been identified as potential supplements that may also act as welcome means to reduce the usage of antibiotics in feedstock, including poultry farming, through manipulation of the gut microbiome. In addition, these compounds may improve the integrity of tight junctions by controlling tight junction-related proteins and inflammatory signaling pathways in the host animals. In this review, we discuss the role of probiotics, prebiotics, and phytogenic substances in optimizing gut function in poultry
