The book provides a complete analysis of European bloodstock sales in 2024 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 2024 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 2024 yearling average by their covering fee of 2022, when the offspring in question were conceived.

Nathaniel

2024 yearling ave: 61,318gns/€74,042

2022 covering fee: £15,000

Profitability index: 4.29

Barely a year goes by without Nathaniel coming up with a Group 1 star. In 2024 it was Irish Oaks heroine You Got To Me who joined the Newsells Park Stud stalwart’s roll of honour, which already contains Channel, Desert Crown, Enable, God Given, Lady Bowthorpe, Mutamakina, Poptronic and Quickthorn.

For all that, Nathaniel hasn’t always been the most commercially popular sire. It appears he has the market’s firm respect now, though, with 25 lots by him bred off a fee of £15,000 sold last year for an average of 61,318gns (€74,042), making a profitability index of 4.29. Blandford Bloodstock bought the most expensive one, a Newsells Park-consigned colt out of the Listed-winning Siyouni mare Sequilla, for300,000gns.
