The answer comes in proper supplementation, using products formulated for the type of rations you are feeding. While no single feedstuff is complete by itself, most feedstuffs can be supplemented to reach all the recommended levels needed to insure healthy growth. It will also supply all the other vitamins and minerals required to keep your adult horse functioning properly. If you are feeding grain hay, grass hay or on pasture, then Select II is the right product for your horse. This formula will give the extra Calcium and Phosphorus to guarantee adequate levels for your horse's metabolism.
Broodmares present a special situation.
During the last trimester of pregnancy, a mare needs even more Calcium, Phosphorus, Copper and Zinc. Mare and Foal is a special formulation of just those minerals that were determined most critical in O.S.U.'s research. Mare and Foal is not a complete supplement by itself. Select I or Select II is the complete vitamin-mineral supplement, and should always be fed with Mare and Foal . No other supplement provides as high a level of the required vitamins and minerals as Select and Mare and Foal Compliment.
