Development of probiotic formulations with immune enhancing activities for chickens

Principal Investigator: Shayan Sharif, University of Guelph
Status: Completed


To further evaluate a previously-developed probiotic with regard to safety, route of administration, and animal health effects under commercial conditions.


Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host through improvements to the intestinal microbial balance. Bacteria with probiotic activity may play a role as alternatives to antibiotic growth promoters and in strategies to control intestinal colonization with microbes that cause food-borne illness in humans, such as Salmonella and Campylobacter. Probiotic bacteria can also influence the development of the immune system. However, a very limited number of probiotic products are currently available with proven immune enhancing capabilities in chickens. Dr. Sharif’s team has developed a formulation containing several lactobacilli with the ability to enhance immune responses and reduce Salmonella burden in chickens. The proposed studies are designed to further evaluate this probiotic formulation.
