THE ART AND SCIENCE OF LIVESTOCK EVALUATION is designed for students studying livestock selection. The main objective of the book is to provide instruction and evaluation on swine, cattle, horses and sheep, with separate chapters supplying current information on the various species of livestock. Information is also included that instructs students on how to compete in and judge competition. The aim is to help students develop the necessary skills to evaluate positive and negative traits such as structural fitness, body fat, muscling, and all the other many qualities used to appraise animals. Chapters are also included that deal with selecting livestock using performance data, and how to evaluate animals based upon live observations and recorded data. The text is also loaded with detailed images and illustrations that provide students with sharp visual examples of normal and abnormal animal traits.

Ray V. Herren, University of Georgia, Athens (Emeritus)

Dr. Ray V. Herren has been actively involved in agriculture for most of his life. He grew up on a diversified farm, where he played a major role in the production of livestock. He obtained a Bachelor of Science degree in agricultural education from Auburn University, a master's degree in agribusiness education from Alabama A & M, and a doctorate in vocational education (with an emphasis in agricultural education) from Virginia Polytechnic Institute and State University. Dr. Herren has taught at Gaylesville High School in Alabama, Virginia Tech, Oregon State University, and the University of Georgia in Athens (UGA), where he retired as head of the Department of Agriculture Leadership, Education, and Communication. In addition to serving as National President in the Future Farmers of America (FFA) alumni organization, he has served on numerous committees from the local to international level, including a national task force to develop FFA programs for middle school and the national committee for career development events. His prolific scholarly activity includes 26 journal articles, 51 invited or refereed presentations, and 12 books and manuals. He has also earned several awards for his commitment to service, including induction into the Georgia Agricultural Teacher Hall of Fame and UGA's prestigious College of Education Outstanding Teaching Award.
