Bacillus Subtilis for an improved microbiota

Managing gut health is key to allow poultry to express their full genetic potential .Any compromise to gut health has a negative effect on both overall health and bird performance .

Gut health can be described as the symbiotic relationship between the host and its microbiota . The interactions between the microbiota , mucosal barrier ,immune system and redox balance have recently been proposed for healthy, predisease states. If there is an imbalance in these interactions, inflammation will occur-Leading to' leaky gut' (increase of the permeability of the intestinal barrier) and other gutrelated disoreders. Probiotics are used in poultry nutrition to improve gut health through their influence on microbiota, gut morphology, inflammatory responses and overall performance.

Probiotics for gut health

Probiotics are live bacteria, which when administered in adequate amounts, confer a beneficial physiological effect on the host.

The most common microorganisms used as probiotics in animal nutrition include: Basilli, lactobacilli, Bifidobacteria, Enterococci and yeasts.

The microbiota

Development and maintenance of robust gut function depend on the composition of the gut microbiota.

These bacteria degrade oligosaccharides and produce short chain fatty acids (SCFAS), butyrate in particular. Butyrate is a very important microbial metabolite, as it represents the main source of energy for enterocytes, cells of the gut wall, and is also now well described as a very potentanti inflammatory compound.

Positive effects on the gut mucosa

The gut mucosa plays an essential role for optimal health and performance  of poultry. This barrier or better named frontier, is the location of many interactions between the animal, the host, and the'outside world. Absorption of nutrients, stimulation of the innate immune system,  but also preventing bacteria and toxins entering the bloodstream underline the functioning of this dynamic frontier.
