Field-scale study of feed additives on broiler gut microbiota and resistome
This study evaluates the effects of non-antibiotic feed additives, including prebiotics, probiotics, and organic acids, on broiler chicken performance, gut microbiota composition, and antimicrobial resistance genes under commercial field conditions. Ileal and cecal samples collected at different time points were analyzed using shotgun metagenomic sequencing to characterize microbial communities and resistome profiles. The project aims to provide insights into sustainable nutritional strategies for improving poultry production and reducing antimicrobial resistance.
