Twelve dogs were used in a crossover design, involving three periods of 6 weeks and three diets: a low-fiber diet (CTR), a cereal-fiber and beet-pulp-supplemented diet (BRA), and a fruit-fiber-supplemented diet (FRU). Each period included a digestibility trial and fecal and blood sampling in the last week. Short-chain fatty acids (SCFAs) and microbiota taxonomy (16S rRNA Illumina-MiSeq) and functionality (Shotgun-NovaSeq 6000) were determined in the feces. General biochemistry, complete blood cells, and lymphocyte subsets were also analyzed. The fiber-supplemented diets showed lower digestibility without significant changes in the fecal consistency. The BRA diet showed higher total SCFA concentrations (p = 0.056), with increases in alpha diversity and particular beneficial genera, such as Lachnospira, Bifidobacterium, and Faecalibacterium. The BRA microbiota was also associated with an overabundance of genes related to carbohydrate and amino acid metabolism. The FRU diet had a distinct impact on the microbiota composition and functionality, leading to higher levels of CD8 lymphocytes. These findings emphasize the importance of selecting the right fiber source when formulating dog diets, as it can have a differential impact on gut microbiota and animal health.<\/jats:p>","DOI":"10.3390\/ani14020196","type":"journal-article","created":{"date-parts":[[2024,1,8]],"date-time":"2024-01-08T03:49:04Z","timestamp":1704685744000},"page":"196","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["The Impact of Fiber Source on Digestive Function, Fecal Microbiota, and Immune Response in Adult Dogs"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6749-6245","authenticated-orcid":false,"given":"Miquel","family":"Montserrat-Malagarriga","sequence":"first","affiliation":[{"name":"Animal Nutrition and Welfare Service, Department of Animal and Food Science, Universitat Aut\u00f2noma de Barcelona, Cerdanyola del Vall\u00e8s, 08193 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7762-192X","authenticated-orcid":false,"given":"Lorena","family":"Castillejos","sequence":"additional","affiliation":[{"name":"Animal Nutrition and Welfare Service, Department of Animal and Food Science, Universitat Aut\u00f2noma de Barcelona, Cerdanyola del Vall\u00e8s, 08193 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5375-6624","authenticated-orcid":false,"given":"Anna","family":"Salas-Mani","sequence":"additional","affiliation":[{"name":"Affinity Pet Care, Hospitalet de Llobregat, 08902 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Celina","family":"Torre","sequence":"additional","affiliation":[{"name":"Affinity Pet Care, Hospitalet de Llobregat, 08902 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5266-0906","authenticated-orcid":false,"given":"Susana M.","family":"Mart\u00edn-Or\u00fae","sequence":"additional","affiliation":[{"name":"Animal Nutrition and Welfare Service, Department of Animal and Food Science, Universitat Aut\u00f2noma de Barcelona, Cerdanyola del Vall\u00e8s, 08193 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,1,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"449","DOI":"10.1146\/annurev-immunol-093019-112348","article-title":"Control of Immunity by the Microbiota","volume":"39","author":"Ansaldo","year":"2021","journal-title":"Annu.
