PMID 41865910 — *[Paraphrased derived summary — non-Open-Access source.]* A 2026 Journal of Equine Veterinary Science study examined how adding a commercial fiber-based feed formulated for both hydration and nutrition affects the equine hindgut microbiome. The authors note that horse health is increasingly linked to the gastrointestinal tract and its microbial community structure, which diet helps shape, and that many such feeds are commercially marketed; the excerpt is cut off before the results are detailed.\n4.
