There are five basic components which must be provided in the right combinations in any animal diet. These are energy, protein, minerals, vitamins and water. The basis for ration formulation should be feed analysis. Feed testing is inexpensive and will allow you to develop a feeding program to meet requirements, while staying away from any unpleasant surprises. Energy Rations for on-line mares are based on medium quality forages primarily as a method of keeping total protein levels in the ration at a maintenance level required for gestating mares.
Forages are high in protein and energy and low in fibre during early growth stages.
As they mature fibre levels increase, resulting in a decrease in protein and energy. Feeding mature low-protein forages requires supplementation with oats or barley grain as an energy source to keep the mares in good body condition.

The general recommendation is to feed one pound of grain per 100 pounds of body weight. Mares are in good body condition if their ribs cannot be seen, but can be felt with light pressure.
