Cornucrescine Daily Hoof Supplement - This is ideal for building and maintain strong, healthy hooves. The Cornucrescine Daily Hoof Supplement uses a superior recipe delivering 20mg biotin for a 500kg horse. Biotin is a vitamin that cannot be produced by the horse. By adding this supplement, this aids a faster hoof growth rate and improves hoof cracks and crumbling of the hoof wall. Provided as a convenient, pelleted formula, a 6kg tub will last for 30 days for an average 500kg horse.
