Preface
Preface
When I first came to L.A. Pierce College, almost 30 years ago, the introduction to livestock production course,
as it was called back then, was being taught by Professor Lindsay Boggess. Its major emphasis was introducing animal,
dairy, and equine science students, general agriculture students, and those pursuing careers in veterinary medicine
to the basic terminology and management procedures associated with the various production animal agriculture enterprises
in the United States. Most students taking the course were production oriented at that time and most came from
families either directly or indirectly connected to animal agriculture.
In the early 1970s, the field of animal husbandry taught the art of raising livestock in a healthy, humane,
and profitable manner. Today, it is animal science and not husbandry that is the main focus of introductory
courses in livestock raising. A tremendous advancement in the use of chemistry, physiology, genetics, molecular
biology, and nutrition, along with animal welfare, has changed the emphasis and interests in production agriculture.
Although the art of animal production is still extremely important and is absolutely necessary for profitable and
humane livestock enterprises, this text will concentrate primarily on the science. We suggest that students take
additional laboratory hands-on courses to learn the art. It takes thousands of hours working with livestock and
a trained master to really learn the art of animal husbandry.
In 1976, when I began teaching in the animal science department at Pierce College, we were using Blakely and
Bade's The Science of Animal Husbandry. For more than two decades, it proved to be an excellent text to
introduce students to this field. I was very fortunate in being asked to help rewrite and edit the sixth edition,
published in 1994. Its use throughout the world at many colleges, universities, and high schools indicates its
popularity.
This first edition of Introduction to Animal Science uses much the same format, photographs, and material
that we included in our last edition of Blakely and Bade's text but adds additional emphasis on more modern husbandry,
science, and welfare concerns of the twenty-first century. I would like to acknowledge and thank Drs. James Blakely
and David H. Bade for their contributions to this text. We have included in this text some additional species that
seem to have caught the interest of many new agricultural entrepreneurs around the United States.
Fourteen chapters covering introductory animal reproduction, genetics, nutrition, breeds, animal health, and
general management of the various common livestock species are included. Some of the chapters are quite large and
are not meant to be covered in one classroom setting but are simply divided into units based on animal species.
At the end of each chapter an evaluation section will assist students in preparing for exams and quizzes. A glossary
is found at the end of the text to enable students to comprehend new terms throughout their reading.
Acknowledgements
I am greatly indebted to Drs. James Blakely and David Bade for their contribution to this text. Their original
work, The Science of Animal Husbandry, formed the basic outline of this text. My longstanding collaborative
relationship with the agriculture faculty at California Polytechnic State University, San Luis Obispo, California
State Polytechnic University, Pomona, the University of California-Davis, and Oregon State University-Corvallis
provided me with a clear understanding of the educational needs of undergraduate agriculture and veterinary students.
It was this understanding that enabled me to recreate this first edition of Introduction to Animal Science.
In particular, I want to acknowledge my former professors, the late Professor Harmon Toone, Dr. Herman Rickard,
Dr. Joe Sabol, Professor Lindsay Boggess, Professor John Barlow, Professor Bernyl Sanden, Dr. Lloyd Swanson, Dr.
Nancy East, Dr. Peter Cheeke, Dr. Dale Weber, and Dr. David Church.
Industry organizations and representatives such as the National Pork Producers Council, Rex Sprietsma of Westfalia-Surge,
Inc., Tom Majeau and Dr. Craig Barnett of Bayer Agriculture Division, Coe Ann Crawford of VetLife, and Lori Wagner
of Sport Horses of Color provided me with invaluable information and photographs that were used in this book.
Several of my colleagues provided meaningful criticism and added information from their areas of expertise.
In particular I want to thank Professors Ronald Wechsler, Liz White, Rebecca Yates, Patrick O'Brien, Jana Smith,
Russ Schrotenboer, and Bill Lander of L.A. Pierce College, Les Ferreira and Joe Sabol of California Polytechnic
State University, San Luis Obispo, and Temple Grandin of Colorado State University, Fort Collins, for their encouragement
and educational insight. I extend a special thank you to reviewers: John Mendes, Modesto Junior College; Mum Nippo,
University of Rhode Island; and Brian J. Rude, Mississippi State University.
I thank my students, 63 of whom are now practicing veterinary medicine. These graduates help me stay in tune
with the fast-moving trends of the new millennium. It is their energy and enthusiasm that drive me and guide me
each semester.
I owe a tremendous appreciation to several individuals at Prentice-Hall who guided me through the development
and editing stages of this text. I would like to especially thank Charles Stewart, Kate Linsner, and Debbie Yarnell
for directing me through the various processes required in preparing this manuscript. Finally, I am particularly
grateful to Lori Dalberg, my production editor, for catching all of my errors prior to publication. She has a tremendous
amount of patience and talent.

Summary
Written for students of general animal science, pre-veterinary, veterinary technology and equine science programs,
Shapiro provides the following benefits to his users:
Balanced coverage of animal science and animal husbandry � discusses the "art" of raising specific
species while covering all of the necessary science. Shapiro addresses animal rights and animal well-being issues,
bringing awareness of the ethics of agriculture to students.
Broad coverage of species � includes information on dairy cattle, goats, beef cattle, sheep, swine, poultry,
horses and rabbits, as well as unusual species, such as the llama and the ostrich, that have recently gained popularity
within agricultural sectors.
Visual coverage � includes breed photos, veterinary photos and working college farm laboratory photos. This
book's art program enhances the learning experience of students with no prior farm experience, as well as those
with farm backgrounds.
A free CD ROM with each new copy of this edition features a self-test for every chapter, in a format that is
engaging and fun and designed to ensure retention of the course material.
