Forage is a horse's main source of nutrition. Generally horse's have access to one, maybe two different types of hay. But unless you are also adding some type of supplemental feed, such as a grain or vitamins and minerals, feeding just hay will not meet the nutritional requirements of a mature horse at maintenance. The nutritional needs of a horse will go up if they are in work or growing which is why balanced nutrition is important.
Just feeding any ol' grain isn't the answer either though. Many cheaper grains are lightly fortified and high in starch and sugars. This generally means that for a horse's nutritional requirements to be met, one must feed a higher quantity of grain. Unfortunately, many do not feed concentrates at the recommended feeding rates. If a feed is underfed, the horse will have lower performance and energy levels, reduced recovery times, a harder time maintaining condition and slower growth rates.
If your horse is getting the recommended amount of feed, and is gaining too much weight, a ration balancer is a great option. These are going to be lower calorie, but are fortified with what is needed for the horse to have a balanced diet. But on the other side of the spectrum, if a horse is not holding weight, the type of grain being fed may not have enough calories or nutrition.
Even easy keepers or ones that look like they are maintain condition without grain can benefit from at least a vitamin and mineral supplement. While some horse's may not seem to have many issues while at rest, as soon as demands are placed on them by either training, exercise, or breeding, issues tend to develop. Some signs of this are lower energy levels, dull coats, or even crumbly hooves.
I always recommend talking to someone that is experienced in nutrition, such as a feed consultant. Not all vets get extensive education in the subject, and feed companies generally will recommend their own products. They are great resources that I utilize, but I recommend specialists whenever there are other concerns such as allergies. Having someone knowledgable that can help you evaluate your feeding regime is invaluable. You pay so much on feed, why not make sure your horse is getting everything it needs?
