Fully updated new edition of a classic quick reference to common surgical procedures in farm animals
Noordsy’s Food Animal Surgery, Sixth Edition is a classic quick reference to surgical procedures in livestock and companion farm animals. With a practical outline format, this book makes it easy to locate essential information on common surgical techniques, presenting 39 chapters across 6 sections for ease of navigation. The book is a helpful memory refresher for procedures or species encountered less frequently, enabling readers to build confidence in learning new surgical techniques.
Chapters review presurgical preparation, perioperative care and restraint, and surgical procedures of the major body systems, and the Sixth Edition has been updated throughout to remove outdated procedures and equipment, making way for new techniques and a focus on evidence-based best practices. Most illustrations have been updated to more accurately depict anatomy, providing surgeons with a clearer understanding of how to perform the procedures, and numerous clinically relevant photographs and illustrations have been added to better convey concepts and techniques.
A companion website allows readers to view and download figures from the text and contains study questions from the end of each chapter along with the answers to those questions.
Noordsy’s Food Animal Surgery includes information on:
- Surgical restraint, local, epidural, general, and postoperative anesthesia/analgesia, surgery of the head and neck, and surgical treatment of cattle with ocular disease
- Umbilical hernias and infections, laparotomy, rumenotomy, fistulation, cannulation, pericardiotomy in cattle, abomasal surgery, surgical treatment of intestinal disease, and rectal prolapse repair
- Surgical treatment of the male and female urogenital systems including conditions associated with urolithiasis and mammary surgery
- Ligament and tendon surgery, foot and claw surgery, joint surgery, and common fractures and dislocations
Noordsy’s Food Animal Surgery is an essential resource for veterinary students and large animal practitioners who care for farm animals.

Lozier’s dedication
To my wife for her love and patience as I continue to take on new challenges, to my parents and siblings who fostered curiosity and instilled in me a thirst for knowledge, and to the Farm Animal team at Ohio State for their constant support.
Niehaus’ dedication
To my parents, Richard and Felicia who instilled in me the values of hard work and perseverance; to my sister, Angela, who has always been a source of encouragement and support; and to my wife, Laurie, and my children, Hannah and Zach, whose unwavering love and patience have been my foundation. Laurie, your support has been especially invaluable, even when this work took time away from us. I also extend my deepest gratitude to the doctors and staff who comprise my work team. Your support and willingness to step in and take on additional responsibilities while I dedicated time to this project have been instrumental. This book is dedicated to all of you.

Preface
The increased attention to welfare of farm animals, the growing number of farm animals kept as pets, the enhancement of food safety, as well as the economic production of food producing animals are critical concerns in today’s agricultural landscape and are cause to rethink surgical procedures on these animals. This book, Food Animal Surgery, emerges from a growing need to provide comprehensive, accessible, and practical information on the surgical procedures that can significantly improve the health and productivity of food animals.
Food Animal Surgery covers a wide range of surgical techniques and procedures essential for the effective management of food animals. While the bovid is the focus of most of the text, key differences and procedures in small ruminants and swine are also described. Divided into six sections, the book begins with general procedures, including restraint for surgical procedures, anesthesia, and pain management. The subsequent sections delve into specific areas such as surgery of the head and neck, abdominal and gastrointestinal surgery, reproductive surgery, and musculoskeletal surgery. From routine surgeries like dehorning and castration to complex procedures like stabilizing long bone fractures and draining the pericardial sac, this book offers detailed guidance on both soft tissue and orthopedic procedures.
Our aim is to create a reference that is both thorough and user‐friendly. Students will find this book to be an invaluable resource for understanding the basic surgical procedures performed in farm animals. Practitioners will appreciate the clear, step‐by‐step instructions complete with updated illustrations that enhance comprehension of the anatomical considerations and the surgical techniques themselves. We also include basic scientific and evidence‐based information to provide context while directing readers to other excellent texts for more in‐depth exploration of specific procedures.
The need for such a text is underscored by the limitations of many existing publications in the field, which often focus heavily on the science behind procedures rather than the techniques themselves. Food Animal Surgery addresses this gap by serving as an easy‐to‐follow manual, allowing practitioners to perform procedures efficiently and effectively.
As research in this field continues to escalate, driven by concerns for animal welfare and food safety, the importance of proper surgical techniques becomes ever more apparent. This book advocates for the use of appropriate anesthesia and analgesia, reflecting a modern approach to farm animal surgery that prioritizes humane treatment and optimal outcomes.
Built upon the strong foundations laid by John Noordsy and Kent Ames, this edition benefits from the contributions of respected leaders in farm animal surgery. The book showcases procedural styles from institutions such as Ohio State, Kansas State, and Michigan State, reflecting a blend of traditional and innovative approaches. This diversity enriches the content, providing readers with multiple perspectives and techniques for procedures.
When considering surgery or alteration of food‐producing animals, ethical concerns must be addressed. We do not support correcting known inherited defects in animals intended for breeding, as this may perpetuate genetic issues. Additionally, many production animals are also used for show or exhibition. Performing surgery to correct cosmetic defects or enhance performance for competitive advantage is unethical. Surgical procedures should be performed to improve animal well‐being and quality of life, in line with our commitment to responsible animal stewardship.
Food Animal Surgery is designed for students, educators, and practitioners in the field of veterinary medicine, particularly those specializing in food animals. It is intended to be easy to understand and followed by non‐surgeons. By reading this book, readers will gain the knowledge and skills necessary to perform surgical techniques with confidence, ensuring better outcomes for animals and contributing to a safer and more sustainable food supply.
We hope this text serves as a valuable tool in your practice and education, enhancing your ability to provide the best possible care for food animals.
Acknowledgments
The authors acknowledge Drs. John Noordsy and Kent Ames, whose extensive experience in farm animal surgery laid the foundation.
