Prebiotics are carbohydrates non-digestible and non-absorbable in the upper gastrointestinal (GI) tract. They stimulate the growth of beneficial microflora in the gut , such as Bifidobacterium and Lactobacillus and consequently increase the production of lactic and acetic acids. This results in a decrease of the development of pathogen enterobacteria.
In addition, the β-glucans and mannanoligosaccharides present on the prebiotics adhere to the bacteria with fimbriae type I such as Salmonella spp. and Escherichia coli, making them agglutinate and become excreted. The increase of the beneficial / pathogenic bacteria relation improves the zootechnical parameters, including feed conversion.
