Read guideWater Intake & Horse Digestion: Why Hydration Matters
How much should a horse drink? Learn how water supports digestion, why dry forage, weather and exercise change requirements, and how hydration affects colic risk.
Read guideGo deeper into the science.
The EquiNectar Science Hub brings together the research behind digestion, hindgut microbial communities, fermentation, fecal pH, metabolomics, short-chain fatty acids and gastrointestinal health. Concern pages link directly to the studies most relevant to them.
Explore individual study records, methods, results, interpretation and links to the original scientific publications.
Explore the scienceDigestive support where it matters.
EquiNectar provides naturally occurring digestive enzyme activities that help break down components of feed and forage before they reach the hindgut. Explore how it can form part of good everyday digestive management.
