With free access to salt licks & water, a horse in low intensity work can take care of it's own fluid balance. In the SP lick, instead of just salt, a number of trace elements have been added that every horse needs, including Biotin for healthy hooves. During the summer, when horses are grazing and the grass isn't as nutritious as it might be, the SP Field Lick can help your horse get the extra vitamins and minerals it needs to maintain optimal condition. This lick will not disintegrate in the rain. It has a hole through the centre and can be mounted on a holder or strung with rope.
