This review explores the effect of nutritional strategies on improving immunity in poultry with special emphasis on additives and diet formulations. Poultry immunity is sensitive to dietary components; nutrients such as antioxidants, essential fatty acids, probiotics, prebiotics, and phytochemicals are critical for modulating immune responses. Incorporating phytogenic feed additives and nutraceuticals into diets has quickly been perceived as a safe, natural strategy to boost poultry immunity. Finally, the emerging concept of precision nutrition, in which diets are designed specifically to the needs of the individual bird, provides a rationale for feeding specific nutrients to optimize immune function. Novel feed processing technologies, such as extrusion, fermentation, and encapsulation, also help improve the bioavailability of immune-enhancing nutrients. The review also pointed out that alternative protein sources like insects and algae fit into this category, making poultry health feasible for outstanding sustainability. The bioinformatics approach package will integrate various omics technologies and personalized nutrition science to specify further immune-enhancing dietary strategies. The extensive review highlights the role of nutrition in enhancing poultry immunity and insights into novel interventions in enhancing poultry health.
