Cecal microbial community of broiler chickens fed experimental diets. A-C Dietary effects of bambermycin and sophorolipid on species diverstiy indexes (Chao1, Shannon, and inversed simpson); D Principal component Analysis ordination plots of microbial communities in the CON, SPL5, SPL10, and SPL15 groups based on the Jensen-Shannon distance metric. Treatment groups: CON, control group fed with basal diet; SPL5, group fed with 5 mg/kg of SPL supplemented diet; SPL10, group fed with 10 mg/kg of sophorolipid-supplemented diet; SPL15, group fed with 15 mg/kg of sophorolipid-supplemented diet
