Fat deposition in meat pigeons is closely related to their intestinal flora. However, few studies have examined the relationship between gut microbiota structure and fat synthesis in pigeons. This study focused on 28-day-old roast squabs of European meat pigeons and Yuzhong pigeons, which exhibit significant differences in fat synthesis and weight. We analyzed the molecular mechanisms by which the intestinal microbiota of different meat pigeons influences fat deposition. Additionally, we evaluated the effects of intestinal digesta from these pigeons on pigeon milk digestion and absorption using a monogastric animal simulation digestive system. Results indicated that the intestinal microflora structures of European meat pigeons and Yuzhong pigeons were significantly different. In European meat pigeons, <jats:italic>Romboutsia<\/jats:italic> promoted fat absorption and utilization by influencing lipid metabolism. In contrast, <jats:italic>Lactobacillus<\/jats:italic> and <jats:italic>Turicibacter<\/jats:italic> in Yuzhong meat pigeons facilitated fat decomposition in roast squab by affecting bile acid transformation and \u03b2-oxidation. Furthermore, gut microbiota can influence the enzymatic activity of acetylCoA carboxylase through biotin synthesis, thereby affecting fat synthesis and the overall transport and deposition of fat in the body. This study reveals, for the first time, the influence of meat pigeons\u2019 gut microbiota on fat digestion and absorption, laying the foundation for developing specialized probiotic products for meat pigeons.<\/jats:p>","DOI":"10.7717\/peerj.20008","type":"journal-article","created":{"date-parts":[[2025,9,9]],"date-time":"2025-09-09T08:42:45Z","timestamp":1757407365000},"page":"e20008","source":"Crossref","is-referenced-by-count":1,"title":["Comparative study of gut microbiota on fat deposition in European meat pigeons and Yuzhong pigeons"],"prefix":"10.7717","volume":"13","author":[{"given":"Zhen","family":"Zhang","sequence":"first","affiliation":[{"name":"Henan Province Engineering Technology Research Center of Livestock and Poultry Biotechnology Industrialization, Henan University of Animal Husbandry and Economy, Zhengzhou, China"},{"name":"College of Animal Science and Technology, Henan University of Animal Husbandry and Economy,  Zhengzhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinghui","family":"Song","sequence":"additional","affiliation":[{"name":"Henan Province Engineering Technology Research Center of Livestock and Poultry Biotechnology Industrialization, Henan University of Animal Husbandry and Economy, Zhengzhou, China"},{"name":"College of Animal Science and Technology, Henan University of Animal Husbandry and Economy,  Zhengzhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dingding","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Animal Science and Technology, Henan University of Animal Husbandry and Economy,  Zhengzhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Na","family":"Luo","sequence":"additional","affiliation":[{"name":"College of Animal Science and Technology, Henan University of Animal Husbandry and Economy,  Zhengzhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liheng","family":"Zhang","sequence":"additional","affiliation":[{"name":"Henan Province Engineering Technology Research Center of Livestock and Poultry Biotechnology Industrialization, Henan University of Animal Husbandry and Economy, Zhengzhou, China"},{"name":"College of Animal Science and Technology, Henan University of Animal Husbandry and Economy,  Zhengzhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Runzhi","family":"Wang","sequence":"additional","affiliation":[{"name":"Nanjing Institute of Animal Husbandry and Poultry Science, Nanjing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhanbing","family":"Han","sequence":"additional","affiliation":[{"name":"College of Animal Science and Technology, Henan University of Animal Husbandry and Economy,  Zhengzhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guirong","family":"Sun","sequence":"additional","affiliation":[{"name":"College of Animal Science and Technology, Henan Agricultural University, Zhengzhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pengkun","family":"Yang","sequence":"additional","affiliation":[{"name":"Henan Province Engineering Technology Research Center of Livestock and Poultry Biotechnology Industrialization, Henan University of Animal Husbandry and Economy, Zhengzhou, China"},{"name":"College of Animal Science and Technology, Henan University of Animal Husbandry and Economy,  Zhengzhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"4443","published-online":{"date-parts":[[2025,9,9]]},"reference":[{"key":"10.7717\/peerj.20008\/ref-1","doi-asserted-by":"publisher","first-page":"37","DOI":"10.1186\/s40104-023-00853-0","article-title":"State of the art in research on the gut-liver and gut-brain axis in poultry","volume":"14","author":"Beldowska","year":"2023","journal-title":"Journal of Animal Science and Biotechnology"},{"key":"10.7717\/peerj.20008\/ref-2","doi-asserted-by":"publisher","first-page":"493","DOI":"10.3390\/molecules24030493","article-title":"The cholesterol-modulating effect of methanol extract of Pigeon Pea (Cajanus cajan (L.)
