Fast releasing energy, such as starchy cereal, produces an instant hit of sparkle.  However, slow release energy, the kind that comes from oil and fibre, does the exact opposite. 

Oils and fats are broken down into fatty acids and the horse’s body finds these more difficult to break down than sugary starch. Digesting and metabolising oil takes more time so this is why it is called ‘slow-release’. The fatty acids that are produced provide more energy than sugar. Oil is also referred to as a calmer and safer energy source; it is easily digested and absorbed so helps support a morelevel-headed horse. Oil can produce an improvement in stamina and also has metabolic advantages.

Fibre is a complex material to break down as a horse’s large and small colon is filled with a bacteria population that processes the fibre.   These micro-organisms break down the fibre and also produce ‘volatile fatty acids’ (VFAs). These fatty acids are then absorbed into the blood stream to be used as energy. 

Slow release energy is less likely to produce excitable behaviour or ‘fizziness’ in horses. It can improve their temperament and promote positive, level headed and calm behaviour.  It is useful for keeping up stamina levels so may be used for eventers and horses whose work requires endurance and stamina.  It can also help to improve the condition of a horse.
