Where will my horse get his energy from?

In some instances – yes.  For example if your horse is in light to moderate work or is on spell then yes, generally he can get his energy/nutritional requirements from his fibre along with a Fibregenix balancer supplement to help balance and maximise his nutrient intake. This is because the digestion of fibre produces volatile fatty acids which can be utilized as an energy source and you can also feed additional oil for a cool energy source if required.

However, all horses and ponies are individuals and some may have greater nutritional requirements than others due to for example a compromised digestive system or having ulcers, so your horse should be assessed on an individual basis, but ultimately a completely fibre diet is preferable and more often than not achievable.  Add in the essential nutrients that Fibregenix will provide and you have the ultimate diet for lower energy requirements.
