When Bloodstock Breeding was first published in 1957, it was hailed as a standard reference work by an authority on the subject. This completely revised and up-dated edition is an acknowledgement that it should remain so, since it takes account of all the significant changes brought about in the last 25 years, which have seen more progressive alterations made to the running of racing than in any other similar period.

Changing patterns in an international trade and economies have had a profound effect on breeding thoroughbreds to race. Yet while the international aspect continues to expand, there is still room for the breeder with one or a few mares to make a telling impact. Bloodstock Breeding is intended to serve and inform all those whose aim is to breed a winning racehorse.

The book is presented in two parts: the theory as it affects all bloodstock breeders, and the practice as it has been borne out in the Derby, which remains the pinnacle of British racing.

The first section deals with the mechanics of breeding, and discusses all matters from basic principles to flights of fancy involving astrology. The second section traces the history of the Derby this century through its winners, with notes on the influence they and their relatives have had. In this section can be found reference to the careers of most well-known horses of this century, including those who have made an important contribution to breeding overseas, from the United States and Canada to Australia and New Zealand.

Sir Charles Leicester spent a life-time in contact with breeding stock in Ireland and elsewhere. His intention was to provide in Bloodstock Breeding information and ideas which would be of importance and practical usefulness not only to thoroughbred breeders, owners and trainers, and students of heredity, but to anyone with a serious interest in the racehorse. This revised edition adheres to his intention.
