'She's very much the matriarch' - You'resothrilling a true blue hen for Coolmore

Despite the fact the bloodstock business is dominated by stallion success stories, the achievements of certain females of the species still stand out as being absolutely exceptional.

The brilliant blue hen Hasili started her own dynasty for Juddmonte, with her five Group/Grade 1-winning offspring, namely Banks Hill, Heat Haze, Intercontinental, Cacique and Champs Elysees, joined by Dansili, who reached the frame in six top-level contests before becoming an important sire.

Urban Sea, herself the dam of no less than four Group/Grade 1 winners, arguably rates the most influential mare of the modern era having bred the breeding-shaping Galileo, sire of an incredible 92 elite scorers himself, and his Derby-winning half-brother Sea The Stars.
