Antibiotic Residues in Muscle Tissues of Lueyang Black-Bone Chickens Under Free-Range Mountainous Conditions and Their Association with Gut Microbiota.

ABSTRACT: The absorption, transport, and distribution of antibiotics in animals are influenced by the composition and function of the intestinal microbial community. However, most existing studies have focused on intensive farming systems involving the artificial addition of antibiotics. For free-range local chicken breeds in mountainous areas without antibiotic additives, systematic research on the presence of antibiotic residues in their muscle tissues and their association with the gut microbiota is lacking. Therefore, in this study, mountainous free-range Lueyang black-bone chickens were selected as the research subjects, employing non-targeted metabolomics and microbiomics to analyze the distribution of antibiotics in intestinal tissues (duodenum and caecum) and muscle tissues (breast and leg m
