Horses have complex digestive systems that require food intake 8-16 hours each day. With the modern day requirements of the horse to be fit for competition and housed conveniently, it is rare that horse owners can fulfil the horses demand for ad lib forage. This is why it is important to feed general health supplements which contain broad spectrum vitamins and minerals. Horses that are stabled overnight are often without food for long periods of time and therefore, feeding vitamin and mineral supplements ensures that they are not losing out on valuable nutrients from the lack of forage. Online for Equine stock a wide range of supplements to keep your horse healthy from brands such as Dodson & Horrell, Feel Good 30 and Maxavita. It should be noted that we always recommend ad lib forage for stabled horses and feeding a supplement does not replace the horses metabolic requirement for hay/haylage or grass.
