摘要As the global population continues to expand,the demand for broiler chicken production to supply safe and high-quality meat is increasing.To meet this ever-growing demand,broiler chickens with enhanced growth performance are being developed,but they often face challenges related to oxidative stress,which can adversely affect gut health.Phytobiotics,which are plant-derived feed additives known for their antimicrobial,antioxidant,immune-modulating,and growth-promoting properties,have emerged as promising natural alternatives to synthetic antibiotics.This review consolidates recent advancements in the use of phytobiotics-derived products from leaves,roots,seeds,flowers,and their extracts in broiler diets reared under standard experimental conditions,without the introduction of stressors.The focus is on elucidating the key mechanisms through which phytobiotics improve gut health,includ-ing their effects on gut morphology,integrity,microflora composition,antioxidant capacity,and immune function.The review highlights the potential of phytobiotics to revolutionize broiler nutrition by acting as natural enhancers of gut health.Research findings reveal that phytobiotics significantly improve intestinal health,and boost growth per-formance,offering a sustainable approach to managing to gut dysfunction.These findings indicate a potential shift in how gut-health related challenges in broilers can be addressed,moving towards natural phytobiotic therapy.How-ever,several challenges persist.Optimizing the dosage of phytobiotics,ensuring consistent performance,and over-coming the limitations related to their extraction and application are key areas requiring further investigation.The review emphasizes the importance of continued research to refine phytobiotic formulations,explore synergistic effects,and incorporate advanced technologies such as Al-driven methods and precision nutrition to tailor feeding strategies more effectively.Additionally,the development of innovative delivery systems,such as nanoencapsula-tion,is suggested as a way to enhance the effectiveness and reliability of phytobiotics.By highlighting the potential of phytobiotics to revolutionize broiler nutrition,this review supports the poultry industry's shift towards antibiotic-free and sustainable dietary solutions,offering new perspectives on the future of broiler chicken production.
