Increasing the intake of prebiotics may boost the number of good bacteria in the gut and has the potential to promote digestibility of nutrients, support the immune system, improve mineral absorption and affect energy, and amino acid balance of the pig. However, the term "prebiotic"  rarely appears on product labels, so it may be difficult to determine whether they are present in a product. Instead, producers should look for the actual names of the prebiotics, such as galacto-oligosaccharides, fructo-oligosaccharides, oligofructose, chicory fiber or inulin in the products of interest.
