Animal disease management in poultry industry is very important. Among the livestock’s diseases, campylobacter jejuni is a leading bacterial cause of food-borne illness in humans. Contaminated chicken meat is considered the most important source of infection with Campylobacter, affecting about 1.3 million people every year. The major aim of this research project is to develop a cost-effective oral delivery platform for anti-bacterial plant extracts and antigens combined with animal feeds to control the bacterial infections in poultry and improve food safety in the chicken industry by the reduction or prevention of C. jejuni colonization and carriage in poultry.
