Rolled Barley

Barley provides more digestible energy and total available nutrients than oats, but it doesn't quite reach the levels of maize. It is less likely to trigger "hot" behaviour. It's considered a good feed for putting condition on a horse, but it's certainly not the perfect feed. It has a poor phosphorous/calcium ratio (maize and oats aren't great either, but barley is the worst of the three). It also lacks vitamins A and D. All cereals require a balancer as the extra phosphorus reduces the ability to absorb calcium.
