"... serious students of the breed and serious breeders of the horse should read this book." A. C. "Woody" Asbury, D.V.M.
Moscow Ballet, with a heart score well above average, is featured in the X-Factor. Harris Farms was used extensively in the research of this book and the book features many of our homebreds. This new publication is available on the above link.
Ever wonder why some stallions seem to be better broodmare sires than sires of sons? The genetic makeup of the horse that dictates the many characteristics of a successful athlete should, by conventional logic, be equally transmitted to both genders of offspring, right? That logic is headed out the window with the publication of an intriguing book, The X-Factor by Marianna Haun. As spokesperson for the group of geneticists and cardiologists, Ms Haun proposes, with some very solid reasoning, that the size of a horse's heart correlates well with its racing performance, and that the inheritance of heart size is linked to the X chromosome. This linkage suggest that the genes related to heart size are passed from stallions to their daughters and then to the next generation. A.C. "Woody" Asbury, D.V.M.
