Some horses and ponies can become over excitable and unpredictable when fed feeds containing a high level of cereals. Cereals contain starch which is digested relatively quickly by the horse producing what is known as “quick release energy”. It is this type of energy than can cause some horses or ponies to become fizzy. To reduce the risk of behavioural problems it is advisable to reduce the amount of cereal starch in the diet. Both SPILLERS® Horse and Pony Cubes and Cool Mix have controlled levels of cereal starch and good levels of fibre to help reduce the risk of over-excitability. We'll help you keep things calm and controlled.
