ボールドルーラー
To bring new blood into their breeding program, the Phippses sometimes negotiated a foal-sharing agreement with other mare owners: Instead of charging a stud fee for Bold Ruler, they would arrange for multiple matings with Bold Ruler, either with two mares in one year or one mare over a two-year period. Assuming two foals were produced, the Phipps family would keep one and the mare's owner would keep the other, with a coin toss determining who received first pick.
