The Role of Phytogenic Feed Additives in Modulating Poultry Nutritional Physiology and Genomics

In this chapter, the effects of phytogenic feed additives (PFAs) on performance, intestinal health, microbiota, oxidative stress, antioxidant defense system, gene expression, and protein production poultry were examined. PFAs consist plant-derived components such as essential oils, flavonoids, saponins, phenolic compounds, alkaloids. They have gained increasing popularity in recent years alternative growth-promoting products to antibiotics used for animal nutrition. Studies indicated that positively affect overall health productivity poultry. Indeed, it has been observed use nutrition enhances modifies microbiota morphology, modulates expression synthesis. Thus, farming is an important transitioning a more sustainable natural system. However, further research needed understand efficacy safety PFAs, interactions between different components, their synergistic effects. Furthermore, determining appropriate levels application methods crucial guide producers reach wider audience farming. conclusion, supporting within framework legal regulations standards sustainability industry consumers.
