Introduction The production environment of extensively raised village chickens necessitates their adaptability to low-resource systems. gut microbiome plays a critical role in supporting this by influencing health and productivity. This study aimed investigate the diversity functional capacities faecal from Limpopo KwaZulu-Natal provinces South Africa. Methods Using combination 16S rRNA gene sequencing shotgun metagenomic technologies, we analysed 98 72 datasets. Taxonomic profiles annotations were derived, focusing on microbial diversity, antibiotic resistance genes (ARGs), potential zoonotic pathogens. Results analysis showed that predominant phyla both Firmicutes, Bacteroidota, Proteobacteria, Actinobacteria. At genus level, Escherichia Shigella prevalent, with coli dysenteriae identified as major contributors microbiome. ARGs identified, MarA , PmrF AcrE detected KwaZulu-Natal, cpxA mdtG, TolA Limpopo. These primarily mediate efflux alteration. Discussion detection bacteria such S treptococcus spp. highlights risks humans through food chain, emphasizing importance improved household hygiene practices. underscores chicken adaptability, linking efficiency settings. Targeted interventions further research are crucial for mitigating enhancing sustainability farming.
