The poultry industry’s shift toward antibiotic-free production has increased interest in functional bioactives that support gut health and performance. Cashew Nut Testa (CNT) tannin, a condensed tannin rich in catechins and procyanidins, demonstrates multiple gut-modulating effects when applied within an optimal inclusion range. Mechanistic studies indicate that CNT tannins inhibit Clostridium perfringens and coccidial development, strengthen intestinal barrier integrity, and modulate mucosal immunity while supporting a balanced gut microbiome. These actions translate into improved feed efficiency, reduced intestinal lesions, lower oocyst shedding, and enhanced meat quality parameters. Proper standardization and dose control are essential, as tannin efficacy is strongly dose-dependent. CNT tannin represents a sustainable, science-based tool for modern poultry nutrition.
