“The harsh reality for breeders is that the costs necessitate good sales returns.”

“There are dangers in following fashion blindly. The most popular, and thereby often the more expensive, stallions also tend to cover the largest books of mares.”

“Good results can be achieved by careful selection and there are definitely various crosses and nicking patterns that can be beneficial, and thereby shorten the odds significantly for a successful outcome.”
Following the death of his wife, Sarah, Martin dispersed the ‘Hinderclay’ flock of Norfolk Horn Sheep in 2013.
However, he is still breeding Glansevin Welsh Ponies and Glansevin Dexterand Hereford Cattle.

Stallion Nominations

Martin Percival offers a ‘niche’ individual and impartial service as a Stallion Nomination Consultant, offering the best professional advice on stallion selection. Benefit from his wealth of knowledge and expertise, acquired over more than thirty five years, to help you to make the right choices. 

His excellent working relationship with stallion studs and the number of nominations booked ensures that he secures the best deals on your behalf.

Pedigree Advice

For those who require more depth of research than Martin can offer informally, he has developed a unique in-depth pedigree research analysis system, with access to Weatherbys’ database.

Matings recommended by Martin in this way have resulted in ten individual Group/Grade winners, including Simply Perfect, winner of the Gr1 UAE Hydra Properties Falmouth Stakes in 2007.


Martin is available to advise existing clients on purchases privately and at auction.

Recent purchases include the young mare Maid For Winning (USA), bought at Tattersalls December Sales in 2011 when her first foal was a yearling. Maid For Winning, who is herself a half sister to Gr1 winner and sire Stroll, is now the dam of three winners with her first three foals, two of whom are Group placed, namely Hors De Combat and Stroll Patrol. Her fourth foal is a yearling filly by Rock Of Gibraltar who has a place in Book 1 of Tattersalls October Yearling Sales. She also has a colt foal by Harbour Watch and is in foal to Charm Spirit. 


The New Approach mare Thiqa (IRE) was bought as a filly out of training at Tattersalls July Sales in 2014. Since then, one of her half sisters, Sun Bittern (USA), has produced the Gr3 winner Signs Of Blessing. Sun Bittern has a filly foal by Invincible Spirit and was covered by Kingman in 2015. Another half sister, Arch Of Colours, is in foal to Charm Spirit and Thiqa is in foal to Zoffany.

Martin Percival has had a lifelong passion for breeding animals. He is particularly interested in ancestry and pedigrees and regards the breeding of Thoroughbred Racehorses as the ultimate challenge.

He has been directly involved in the Bloodstock industry since 1972, when he spent two years gaining practical experience of all aspects of stud work at Bourchiers Hall Stud, which was located about 35 miles south east of Newmarket. Following that he spent some time working in the Pedigree Department of The British Bloodstock Agency, before joining Pacemaker Publications in London in 1980. In 1985 he returned to The British Bloodstock Agency, to join the team of their Stallion Department, which at that time was directly responsible for the management of about forty stallions based in England, Ireland and France. In 2007 Martin left the BBA and established Martin Percival trading as Boyce Bloodstock Limited.
