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.

Coulsty has proved himself a firm friend of breeders on a budget, supplying a decent number of fast, early winners while standing at Rathasker Stud at chicken-feed fees.

The son of Kodiac provided his supporters with plenty of good results at the yearling sales last year from a low cost base. Some 37 of his lots changed hands for an average of €32,922 (25,913gns), led by Rathasker's own half-sister to Derby favourite Pierre Bonnard who made €200,000 from Amo Racing.
