Fiber as a prebiotic for poultry: a review

Abstract

The review was elaborated to know the effect of the fiber used as a prebiotic in broilers and hens for production. A review of the generalities of fiber and the benefits it provides on immunity, digestive development, nutrient digestibility and productive performance was carried out. It was found that fiber as an additive can be included at levels of less than 3% to improve the immune response of broiler, increase the development of intestinal villi and the amount of cytokines that regulate chemotaxis, limiting the permeability of toxic substances into the bloodstream. Furthermore, it regulates the inflammatory response of the intestine. Fiber stimulates the intestinal microbiota, preventing the adherence and development of pathogenic bacteria, as well as the production of antimicrobial peptides. In addition, fiber can regulate intestinal motility, the general microbiota, the accumulation of lipids in the liver, lower cholesterol, liver function, reduce pollutant emissions and the absorption of nutrients. Therefore, it is concluded that fiber as a prebiotic can be an alternative in broiler to improve the productive performance of birds as an alternative to synthetic additives.
