Federico Tesio (1869-1954) is the most successful breeder of Thoroughbreds in the history of racing. The horses he bred at his Dormello Stud on the banks of Lake Maggiore in northern Italy continue to have a genetic impact on Thoroughbreds around the world.This new, faithful translation of Tesio's 1947 work Puro-Sangue - Animale da Esperimento (The Pure Blood - An Animal of Experimentation) captures every idea and nuance of the original Italian text. In it, the reader will find this great breeder's own views on genetics and the Thoroughbred as a hybrid, what he looks for in the first 64 ancestors of a horse's pedigree, why heavily-raced horses rarely produce successful offspring, and more. He also shares his ?Law of Changeable Maximums? and ?Law of Similar but not Identical.'Federico Tesio has been the envy of racehorse breeders for generations. Now Tesio: In His Own Words can help unlock the secrets to his success.Tesio, Federico is the author of 'Tesio In His Own Words' with ISBN 9780929346762 and ISBN 0929346769.
