Special Issue Information

Dear Colleagues,

The gut microbiota is crucial in animal health and performance, interacting closely with dietary components. Recent research has highlighted how one’s diet shapes the gut microbiota, affecting immune function, nutrient absorption, and overall health. However, the complex interactions between diet and the gut microbiota remain poorly understood, especially across animal species and production systems.

This Special Issue focuses on the relationship between diet and the gut microbiota in animals (e.g., pigs, ruminants, poultry, or pets), examining how these interactions influence health, growth, and disease resistance. The scope of this Special Issue includes, but is not limited to, the following topics: (1) dietary modulation of the gut microbiota; (2) the role of the gut microbiota in nutrient metabolism; (3) the gut microbiota and immune function; (4) comparative studies across species; and (5) technological innovations in microbiota analysis.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Microorganisms is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Glucose oxidase (GOD) is a natural enzyme with antioxidant and antimicrobial properties but its effects on sows remain insufficient. This study investigated the effects of dietary GOD supplementation during gestation on inflammatory response, antioxidant capacity, immune function, and gut microbiota of farrowing sows. Twenty-four primiparous sows were randomly assigned to two groups and fed a basal diet or a basal diet supplemented with GOD (300 mg/kg diet) from gestation day 30 to farrowing. GOD supplementation significantly increased triglyceride, superoxide dismutase, and immunoglobulin M levels (p < 0.05), and significantly decreased alanine aminotransferase and interleukin-6 levels in serum (p < 0.05); significantly reduced placental interleukin-1β, malondialdehyde and tumor necrosis factor-α concentrations and NF-κB gene expression (p < 0.05), and elevated glutathione peroxidase activity and relative mRNA expressions of Nrf2, HO-1, GPX1 and SOD2 (p < 0.05). Moreover, GOD supplementation altered the fecal microbial community structure (p < 0.05), significantly reducing Clostridium, dgaA-11_gut_group, Bacteroides, and Prevotellaceae_NK3B31_group abundance (p < 0.05), while enriching Lachnospira, unclassified_f_Erysipelotrichiaceae, and Anaerostipes (p < 0.05). Collectively, 300 mg/kg glucose oxidase supplementation during mid-to-late gestation improved the health status of farrowing sows by improving nutrient utilization, immune function and antioxidant capacity, and altering fecal microbial structure and relative abundances.
