With the reduced availability of antibiotics, poultry producers are looking for feed additives to stimulate the immune system of their birds. Some beta-glucans have been shown to improve gut health in poultry subjected to a bacterial challenge, to increase the flow of new immunocytes into the various lymphoid organs, to increase macrophage function, to increase antibody titers after a vaccination and to function as an anti-inflammatory immunomodulator. As a result, beta-glucans may provide a tool for producers trying to reduce or eliminate the use of antibiotics in poultry diets.
