A daily ration should contain a mixture of roughage, that is hay, chaff, fibre plus and or pasture and grains or concentrates.
Your minimum roughage intake should be approximately 1% of your horse’s bodyweight.
A horse spelling or only doing light work really only needs a diet of good quality roughage and minimal grain. The more work they do, the more you need to increase the grain content of their diet to cater for their increased energy requirement.
