The horse has evolved a requirement for minimum amount
of dietary fibre, which provides a food source for micro-organisms, primarily
in their hind gut (caecum and colon). As such, they are able to digest very
little starch at any one time – their small intestine struggles to deal with
more than 3-4g of starch per kilogram of body weight per meal (Potter et al.,
1992) and problems can occur at levels of ~2g. If we consider that oats are
~43% starch, this equates to just over 2kg of oats per meal for a 500kg horse.
In fact, current recommendations are as low as 1g of starch per kg of
bodyweight per meal (Vervuert, 2009), so around 1kg of oats per meal for the
same horse.
(Yea-Sacc is a yeast culture based on a proprietary
strain of Saccharomyces cerevisiae, a yeast strain specifically selected for
its influence on animal performance. With a low inclusion rate and a large body
of research clarifying its mode of action and performance responses, Yea-Sacc
is ideal for beef, dairy, calf and equine feeds.)
