Rural smallholder farmers in these regions usually adopt the free\u2010range (backyard) production system, which exposes the poultry to diverse environments and a broad spectrum of microorganisms that influence their diet and gut microbiota. In this cross\u2010sectional purposive study, we evaluated the microbial community profiles of indigenous backyard poultry and their antimicrobial resistance genes (ARGs) using both cecal samples, which provide a more accurate representation of the core gut microbiota, and fecal samples, which allow for noninvasive monitoring and pathogen screening. We analyzed 32 pooled fecal and cecal samples using shotgun metagenomics, followed by functional and antimicrobial resistance (AMR) analyses to identify genes and metabolic pathways associated with poultry gut health and production. We report the presence of many commensal microorganisms in indigenous backyard poultry, with the most abundant being Bacteroidetes, Firmicutes, and Proteobacteria. The most dominant genera in the feces were\n                    <jats:italic>Bacteroides<\/jats:italic>\n                    ,\n                    <jats:italic>Methanobrevibacter<\/jats:italic>\n                    , and\n                    <jats:italic>Phocaeicola<\/jats:italic>\n                    , while\n                    <jats:italic>Bacteroides<\/jats:italic>\n                    ,\n                    <jats:italic>Methanobrevibacter<\/jats:italic>\n                    , and\n                    <jats:italic>Chlamydia<\/jats:italic>\n                    dominated in the ceca. No marked differences in microbial diversity were observed between the fecal and cecal samples. KEGG and COG database analyses revealed significantly enriched pathways associated with metabolism, cellular processes, and information storage and processing. Genes that confer resistance to tetracycline were the most abundant, raising concerns about the risks associated with inappropriate and excessive use of this antibiotic in poultry treatment. These findings deepen our understanding of the poultry gut microbiome, particularly regarding indigenous backyard poultry. Furthermore, the information about ARGs is a valuable indicator of antimicrobial use by rural smallholder farmers who have adopted the free\u2010range production system in Kenya and other developing countries. These insights are crucial for farmers and the national livestock sector to monitor AMR in poultry, thereby enabling improved poultry management practices and informed policy decisions.\n                  <\/jats:p>","DOI":"10.1155\/ijm\/7306065","type":"journal-article","created":{"date-parts":[[2026,1,25]],"date-time":"2026-01-25T15:15:03Z","timestamp":1769354103000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Metagenomic Profiling of Fecal and Cecal Microbiota and Their Antimicrobial Resistance Genes in Indigenous Backyard Poultry"],"prefix":"10.1155","volume":"2026","author":[{"given":"Philip M.","family":"Panyako","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8292-7085","authenticated-orcid":false,"given":"Stephen","family":"Ogada","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephen N.","family":"Kuria","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John","family":"Musina","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jacqueline K.","family":"Lichoti","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0780-0399","authenticated-orcid":false,"given":"Sheila C.","family":"Ommeh","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,1,25]]},"reference":[{"key":"e_1_2_11_1_2","volume-title":"Rome","author":"Food and Agriculture Organization of the United Nations","year":"2022"},{"key":"e_1_2_11_2_2","unstructured":"NyagaP.
