The book provides a complete analysis of European bloodstock sales in 2025 for all foals, yearlings and older horses in Britain, Ireland, France, Germany and Italy. It also includes foals and yearlings either foaled in Europe or by European-based sires at the major auctions in North America and Japan.

Furthermore, the Bloodstock Sales Review features comprehensive overviews of the trading year for Tattersalls, Goffs, Tattersalls Ireland and Arqana, as well as tables of the leading sires of 2025 by yearling average, lists of the year’s most expensive yearlings and foals, and a roll of top historical auction prices.

To mark the publication of the book, we compiled a top ten of the most profitable British and Irish-based yearling sires last year.

We have worked out each sires’ profitability index by dividing their 2025 yearling average by their covering fee of 2023, when the offspring in question were conceived.

In ninth place...

2025 yearling ave: 68,192gns/€86,638

2023 covering fee: €17,500

Profitability index: 4.95

Sioux Nation has really endeared himself to the industry by being a reliable source of precocious and pacey performers with a touch of class – including Poule d’Essai des Pouliches first-past-the–post Shes Perfect and Rockfel winner Zanthos last year. 

Coolmore’s son of Scat Daddy is immensely popular with end-users and traders alike, and that helped his fifth crop of yearlings sell for nearly five times the covering fee, even though that had been given a significant increase after he showed promise with his first juveniles.
