Alterion is a cutting-edge probiotic developed by Adisseo for poultry. Using a unique Bacillus subtilis strain, it enhances gut health and boosts animal performance. Alterion works by rebalancing the gut microbiota, positively impacting both performance and microbial balance.

Its spore-forming nature ensures effective activation in the small intestine, delivering consistent results in poultry production. Beneficial during stressful periods, it helps birds maintain performance even under challenging conditions.

Available in two variants—Alterion NE (concentrated) and Alterion (diluted)—it caters to different needs. Alterion promotes intestinal health, improves feed efficiency, and supports poultry well-being.

Key benefits

Resilient Microbiota

Alterion boosts microbial activity by increasing polysaccharide-degrading and butyrate-producing bacteria.

Strengthened Gut Barrier

Alterion strengthens the gut barrier by increasing the expression of tight junction proteins, enhancing intestinal integrity.

Controlled Inflammatory Response

Alterion controls inflammation by inhibiting IκB degradation, preventing NF-κB translocation and regulating IL-8 and iNOS.

Enhancing gut resilience

Alterion is made of Bacillus subtilis spores attached to calcium carbonate particles. Its action begins with the germination and growth of beneficial microorganisms in the bird's gut, producing metabolites vital for gut health and digestion.

Alterion acts on 3 lines of resilience:

Microbial ecology,
Gut morphology and integrity
Inflammatory response.

These actions create a robust, balanced gut environment, improving the bird’s well-being, performance, and productivity in a sustainable way.
