All Mares from St. Clair Farms are designated by a brand on their left shoulder that follows their lineage. For example, when mare #12 has a foal, that foal will bear the same number 12 on its left shoulder. The sire brand is marked on the horse’s right butt, with the last two digits of the year it was foaled on the left. The St. Clair Farms brand is located on the left hip.
