We might consider that it’s sufficient to supply the 9 VITAMINS that are always missing in the daily feed but the true situation is much more complex.
First, because in terms of vitamins, it’s always a question of synergy and antagonism ; it’s useless to supply only one vitamin if you do not supply the others as well. What is essential is not the quantity of each vitamin but the balance between these active micronutrients. If the supply of one of them is wrong, the complete balance is affected.
That’s the reason why we recommend daily supplies of all 14 vitamins to supplement the horse's traditional feed.
Then, for the supply of these 14 vitamins, 2 important parameters must be taken in account :
• Their bioavailability:
only limited amounts of most of the vitamins contained in feed ingredients are released during digestion. Many of them are strongly bound to protein molecules as co-enzymes. The biovailability of each vitamin has been taken into account in
table 4
• the type of horse and the intensity of the training
Considering these two parameters it has been possible to definethe ideal vitamin supplementation for different types of horses (table 5 ).
