Multi-site swine production volumes represent a sine qua non of 20th century animal husbandry achievement. Differentiating the techniqes applied to cattle or any other ungulates. Whilst at Cornell, I had the good fortune to hear Dr. Harris speak, and this book reflects both the intellect and the ability to convey information that one appreciates when attending a lecture. For me, the academic study of this topic is fulfilling on a number of levels, from the dry but necessary scientific research and publication, to the earthy warmth one feels in the pen, I share the attachment of Dr. Harris to this subject, and post-doc, intend to make it my life's work. Bravo Dr. Harris!
