This study aimed to investigate the internal connections between starch digestion properties and microbial changes in the gastrointestinal tract of broiler chickens. A total of 240 male AA+ broilers (21-day-old) were allocated to 4 treatments of regular and waxy corn with and without virginiamycin (...
