Did you know Volatile fatty acids (VFAs) from quality fibre can supply up to 70% of the daily energy needs of a mature horse? Here's why it's such a good energy source...
🌿Horses evolved grazing pasture for 16-18 hours a day and their digestive system is engineered to process that fibre, converting it into energy through fermentation.
🌿When fibre reaches the hindgut, billions of beneficial microbes ferment it and produce volatile fatty acids (VFAs), which are absorbed and used as energy.
🌿The VFAs produced from fibre fermentation (acetate, propionate and butyrate) each play important roles in the horse’s body, providing slow-release energy, supporting glucose production and even helping maintain healthy hindgut cells.
🌿Fibre fermentation doesn't just produce VFA's, it also produces important nutrients like B group vitamins (including biotin) and vitamin K.
🌿The more quality fibre they eat, the stronger their gut microbiome gets, which means more fermentation, more VFA production, and more usable nutrients from every bite.

QUALITY MATTERS!
🏆Quality fibre sources are highly digestible and more efficiently fermented by microbes to produce a greater amount of nutrients. These include quality pasture and hay, lupin hulls, beet pulp and soy hulls.
👎Poor quality sources are high in indigestible fibre or lignin, which microbes can't break down and extract nutrients from. Examples include overly mature or stalky hays or pastures.
⚡Other energy sources matter too:
Starches, sugars and fats also play important roles in fuelling different metabolic pathways. Depending on your horse’s workload, condition, life stage and energy demands, these energy sources can help support performance, rapid energy availability, weight gain and athletic output, but should always be added to suit your individual horse's needs.
If you're looking for additional quality fibre, try adding Lupin Fibre Cubes or Lupin Fibre Boost to your horse's diet.
