Abstract: Poultry production plays a vital role in mitigating global nutritional deficiencies within the animal protein supply system.However,its sustainable development is persistently challenged by pathogenic diseases caused by bacteria,viruses,and other pathogens,which not only increase the overall cost of disease prevention and control but also elevate flock mortality rates and impair production performance.In this context,plant polyphenols are emerging as a key focus in the development of novel feed additives.These natural compounds,widely present in plant secondary metabolites,encompass over 8 000 structurally diverse types,including major subclasses such as flavonoids,phenolic acids,and lignans.Their unique phenolic hydroxyl groups confer exceptional antioxidant,anti-inflammatory,and broad-spectrum antimicrobial properties.Nevertheless,the strong polarity of polyphenols results in low permeability across the small intestinal brush border membrane,and their structural degradation in the gastrointestinal environment results in bioavailability typically below 10%.To address this challenge,cutting-edge research is exploring nanoencapsulation technologies (e.g.,chitosan nanoparticles) and molecular structural modifications (e.g.,acylated/methylated derivatives) to enhance hydrophobicity and metabolic stability,thereby overcoming absorption barriers.To gain a more comprehensive understanding of the potential of polyphenols in poultry farming,the author summarizes their sources,structural classification;biological functions such as antioxidant,anti-inflammatory,and antimicrobial effects;and their applications in poultry production.
