The world's supplies of protein are significantly influenced by the poultry sector, and each year, the number of poultry produced globally grows larger. However, the poultry business is dealing with a variety of problems, such as bacterial infection, coccidiosis, oxidative stress, food pad dermatitis (FPD), and environmental pollution, which affect food safety, poultry production efficiency, animal welfare, and the environment. In addition, limitations on the use of antibiotic growth promoters (AGP) have made a number of these adverse consequences worse. Since high doses of tannins can reduce feed intake and negatively impact nutrient digestibility and absorption, they have historically been viewed as antinutritional factors. However, recent research has shown that some tannins, when used in the right way, can improve the intestinal microbial ecosystem, enhance gut health, and consequently increase productive performance. Tannins, on the other hand, have been found to possess antibacterial, antioxidant, anti-parasitic, immunomodulatory, and anti-inflammatory characteristics; as a result, they have attracted attention as prospective bioactive substances to aid in easing the difficulties of AGP removal in the chicken sector. In order to diminish the need for AGP and otherwise increase poultry production efficiency, tannin supplementation, either alone or in combination with the other measures, may be a successful strategy.
