The application of probiotics in poultry nutrition is now a key approach to strengthening health and increasing resistance to various diseases. In addition to helping maintain the balance of the gut microbiota, probiotics can also influence the immune system, both innate and adaptive, thus enhancing the body's ability to fight pathogens and supporting successful vaccination [136]. However, immune activation is energetically demanding, and excessive or chronic immune stimulation may divert nutrients away from growth and production, potentially impairing feed efficiency and overall performance. Therefore, the goal of probiotic supplementation is to achieve balanced immunomodulation rather than maximal immune activation. A comprehensive understanding of how probiotics modulate immunity is an essential foundation for developing sustainable poultry nutrition strategies.
