Our goal in writing this book was twofold: fi rst, to provide
the most up-to-date and comprehensive book available
on diseases of the individual dairy cow and, second,
to honor Dr. William Rebhun. It was a privilege to have
both worked with and learned from Bill, and we shall be
forever indebted to him for knowledge gained. Dr. Francis
Fox eruditely describes Bill in his dedication, and those
who knew Bill, either student, colleague, or client, will
warm to Dr. Fox’s description of Bill’s humor, pragmatism,
and, above all, professionalism. It is in the spirit of
his commitment to the art, as well as to the science, of
bovine medicine that this book is dedicated.
